Summary of the invention
Technical problem to be solved by this invention is to provide to above-mentioned prior art present situation under a kind of state of after lock core turns to first opening angle, extracting master key, inserts emergency key again and can drive lock core is rotated further certain angle on the basis of first opening angle cylinder lock.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of cylinder lock, and include the lock shell, be installed in cylindrical lock core in the lock shell, have a keyhole in the lock core, be interval with vertically in the lock core and ranked first the pellet shot from a slingshot hole more; It is characterized in that: be interval with vertically in the described lock shell and ranked second pellet shot from a slingshot hole and ranked third the pellet shot from a slingshot hole more more, the axis in the second pellet shot from a slingshot hole and the 3rd pellet shot from a slingshot hole mutually at an angle; Movable sleeve is provided with a lining on the said lock core, and this lining is between lock core and lock shell, and the row and the first pellet shot from a slingshot hole more than said lining upper edge axially spaced-apart is provided be the pellet shot from a slingshot through hole one to one; Corresponding one by one connection of the said first pellet shot from a slingshot hole, pellet shot from a slingshot through hole and the second pellet shot from a slingshot hole forms complete main marble hole, and main pellet shot from a slingshot assembly is housed in each main marble hole, and main pellet shot from a slingshot assembly can be inserted into the master key promotion of keyhole and remove the locking between lining and the lock shell; It circumferentially has the first arc stopper slot said lining perisporium upper edge, and is fixed with the lining limited post on the said lock shell, and the end of this lining limited post gets in the first arc stopper slot lining is carried out rotary spacing after stretching out lock-shell lining; Under the state after lock core rotates an angle; Corresponding one by one connection of the said first pellet shot from a slingshot hole, pellet shot from a slingshot through hole and the 3rd pellet shot from a slingshot hole forms complete emergent pellet shot from a slingshot hole; In each emergent cylinder lock the Emergency bomb sub-component is housed, the Emergency bomb sub-component can be inserted into the emergency key promotion of keyhole and remove the locking between lock core and the lining.
As improvement; It circumferentially also has the second arc stopper slot above-mentioned lining perisporium upper edge; This second arc stopper slot and the first arc stopper slot are axially spaced apart from each other, are fixed with a lock core limited post on the said lock core, and the end of this lock core limited post gets into the second arc stopper slot so that lock core is carried out rotary spacing after passing the lock core periphery wall; Before the relative lining of lock core rotated, an inside wall of this lock core limited post and this second arc stopper slot was conflicted.
The slide guide retaining of this second arc stopper slot and lock core limited post is joined effect; Have and to lock the effect that shell continues the restriction of leading rotation maximum angle relatively to lock core; Mainly also rise when lock core is locked the shell revolution relatively, detect lock core and whether turn round the effect that puts in place, when lock core returns back to lock core limited post and the conflict of the second arc stopper slot, one side inside wall; Emergency key can not continue to drive lock core and lock the shell revolution relatively, just learns that lock core is turned back to normal opening (and first opening angle state) this moment; Do not join effect if there is the slide guide retaining of the second arc stopper slot and lock core limited post certainly; We also roughly can know when emergency key turns to vertical or level; Lock core just is turned back to normal opening (and first opening angle state); At this moment can extract emergency key, otherwise lock core emergency key when other position can not be pulled out.
The axis in above-mentioned second pellet shot from a slingshot hole and the 3rd pellet shot from a slingshot hole is mutually the angle of 90 degree; The radian of the said first arc stopper slot is 90 degree.The unlatching of general cylinder lock is good with key turns 90 degree.
Having the main pellet shot from a slingshot assembly in the main marble hole in above-mentioned each main marble hole at least is three billiards structures; Having an Emergency bomb sub-component in the emergent pellet shot from a slingshot hole at least in said each emergent pellet shot from a slingshot hole is three billiards structures.Three billiards structures can increase the close quantity of marble lock key.
For ease of assembling pellet shot from a slingshot assembly; Above-mentioned lock shell is made up of cover in the lock and lock overcoat; The periphery wall that puts in the lock and run through cover in the lock is located in described second pellet shot from a slingshot hole and the 3rd pellet shot from a slingshot hole, and described lock is locked outward, and to be enclosed within cover in the lock outer and with the outer end opening sealing in the second pellet shot from a slingshot hole and the 3rd pellet shot from a slingshot hole.The routine techniques that it adopts for the lock shell.
For making aforementioned cylinder lock have the emergency opening function; Above-mentioned cylinder lock also comprises main plectrum and emergent plectrum; Wherein, Said main plectrum also can rotate with lock core with the inner of lock core is fixing, and said emergent plectrum axial limiting has the promotion post of evagination in the inner and lock core deflection relatively of lock core on the said main plectrum end face; Have on the said emergent plectrum and supply said promotion post to insert and the arc guide groove of slippage, the number of degrees of the radian of this arc guide groove and the axis in the second pellet shot from a slingshot hole and the 3rd pellet shot from a slingshot hole number of degrees at an angle to each other are identical.
Under the state that inserts master key; Master key drives lock core, lining and main plectrum and locks shell deflection certain angle relatively, after lock core and lining turn to an angle (this angle can be claimed first opening angle), because the lining limited post is to the gear of the first arc stopper slot; Stop lining further to rotate; And lock core is to link to each other through pellet shot from a slingshot with lining, so lock core can not further rotate, the main plectrum that links to each other with lock core can not further rotate; Under this state, the promotion post on the main plectrum and the inside wall of arc guide groove are just conflicted; At this moment extract master key and insert emergency key, emergency key is removed the locking between lock core and the lining, rotates emergency key; Continue to drive the relative lining deflection of lock core; The main plectrum that links to each other with lock core also is rotated further certain angle on the basis of first opening angle, main plectrum drives emergent plectrum deflection certain angle, the electronic lock in the emergent plectrum touching strongbox; Mechanically open electronic lock, therefore have emergency function.
Have the circular mounting hole on the above-mentioned emergent plectrum; Accordingly; First installation portion that has protrusion on the inner face of said lock core; The cross section of this first installation portion is the circle that matches with described circular mounting hole, and said emergent plectrum is movably set on this first installation portion through the circular mounting hole; Have an irregularly-shaped hole on the described main plectrum; Accordingly; On the end face of said first installation portion, also have the shape of protrusion and second installation portion that irregularly-shaped hole matches; Have screwed hole on the end face of this second installation portion, described main plectrum is set on this second installation portion through irregularly-shaped hole, and externally with the screw axial limiting that is connected with said screwed hole.It is the concrete mounting structure between a kind of main plectrum and emergent plectrum and the lock core, and this mounting structure has convenient installation.
Compared with prior art, the advantage of this billiards lock structure is: under the state that inserts master key, master key promotes main pellet shot from a slingshot assembly; Remove the locking between lining and the lock shell; And lock core is to link to each other through pellet shot from a slingshot with lining, so master key drives lock core and lining is locked shell deflection certain angle relatively, after lock core and lining turn to an angle (this angle can be claimed first opening angle); Because the lining limited post is to the gear of the first arc stopper slot; Stop lining further to rotate, lock core also just can not further rotate, and that is to say that master key can only drive lock core at the first opening angle intrinsic deflection; After lock core is opened to first opening angle, to extract master key and insert emergency key, emergency key is removed the locking between lock core and the lining; Because the effect of lining and lining limited post and corresponding pellet shot from a slingshot; Lining can not be locked shell relatively and rotate, if rotate emergency key, continues to drive the relative lining deflection of lock core; Be that lock core is rotated further on the basis of first opening angle, finally arrive second opening angle; Therefore this cylinder lock can have two opening angles, uses as emergent lockset simultaneously on the basis that makes this cylinder lock may be used on using as common lockset on the strongbox.

Shown in Fig. 1～26, be a preferred embodiment of the present invention.
A kind of cylinder lock; Include lock shell 1, be installed in cylindrical lock core 2 in the lock shell 1, lock shell 1 is made up of cover 11 in the lock and lock overcoat 12, has a keyhole 21 in the lock core; Be interval with vertically in the lock core 2 and ranked first pellet shot from a slingshot hole 22 more, this first pellet shot from a slingshot hole 22 is communicated with keyhole 21.
Cover 11 perisporium upper edge axially spaced-aparts are provided with and ranked second pellet shot from a slingshot hole 3 more in the lock; Also be interval with vertically on cover 11 perisporiums in the lock and ranked third pellet shot from a slingshot hole 4 more; The periphery wall of cover 11 in the lock is run through in the second pellet shot from a slingshot hole 3 and the 3rd pellet shot from a slingshot hole 4; It is outer and with the outer end opening sealing in the second pellet shot from a slingshot hole 3 and the 3rd pellet shot from a slingshot hole 4 that lock overcoat 12 tightly is enclosed within cover in the lock 11, and the axis in the second pellet shot from a slingshot hole 3 and the 3rd pellet shot from a slingshot hole 4 is mutually one 90 angle of spending.
Lock core 2 periphery movable sleeves are provided with a lining 5; This lining 5 overlaps between 11 in lock core 2 and lock; The row and the first pellet shot from a slingshot hole 22 more than lining 5 upper edge axially spaced-aparts are provided be pellet shot from a slingshot through hole 51 one to one; Form first interface between cover 11 internal perisporiums in lining 5 outer peripheral faces and the lock, form second interface between lining 5 internal perisporiums and lock core 2 outer peripheral faces.
Corresponding one by one connection of the first pellet shot from a slingshot hole 22, pellet shot from a slingshot through hole 51 and the second pellet shot from a slingshot hole 2 forms complete main marble hole; Main pellet shot from a slingshot assembly is housed in each main marble hole, and this main pellet shot from a slingshot assembly can be inserted into the master key 7a promotion of keyhole 21 and remove lining 5 and lock the locking between the shell 1; Every group of master's pellet shot from a slingshot assembly includes spring 13, reaches two or three pellets shot from a slingshot 14 that length is different; Having the main pellet shot from a slingshot assembly in the main marble hole in each main marble hole at least is three billiards structures; When inserting keyhole 21 pushers, master key 5 moves sub 14; At this moment as rotation master key 7a make that first interface between the cover 11 flushes in interface and lining 5 and the lock between two pellets shot from a slingshot, and the pellet shot from a slingshot 14 that is positioned at lock core 2 is positioned at the first pellet shot from a slingshot hole 22 and pellet shot from a slingshot through hole 51 simultaneously; Just can drive lock core 2 and lining 5 lock shell 1 rotation relatively simultaneously, the operating principle of main pellet shot from a slingshot assembly is identical with existing cylinder lock.
It circumferentially has the first arc stopper slot 52 lining 5 perisporium upper edges; The radian of the first arc stopper slot 52 is 90 degree; And be inserted with lining limited post 6 on the cover 11 in the lock; Cover 11 is fixing in lining limited post 6 and the lock, gets into behind cover 11 inwalls in the end of this lining limited post 6 is stretched out and locked in the first arc stopper slot 52 so that lining 5 is carried out rotary spacing, promptly after cover 11 in the lining 5 relative locks turns to an angle (present embodiment is 90 degree); The inwall touching of lining limited post 6 and the first arc stopper slot, 52 1 sides is rotated further so lining 5 can not be locked interior cover 11 more relatively.
Under the state after lock core 2 rotates an angle; Corresponding one by one connection of the first pellet shot from a slingshot hole 22, pellet shot from a slingshot through hole 51 and the 3rd pellet shot from a slingshot hole 4 forms complete emergent pellet shot from a slingshot hole; In each emergent cylinder lock the Emergency bomb sub-component is housed, this Emergency bomb sub-component can be inserted into emergency key 7 promotions of keyhole and remove the locking between lock core 2 and the lining 5; Every group of Emergency bomb sub-component includes spring 13, reaches two or three pellets shot from a slingshot 14 that length is different; Having an Emergency bomb sub-component in the emergent pellet shot from a slingshot hole at least in each emergent pellet shot from a slingshot hole is three billiards structures; When master key 5 inserts keyholes 21 pushers 14 of moving, the interface between two pellets shot from a slingshot is flushed with second interface between lock core 2 and the lining 5, and the pellet shot from a slingshot 14 that is positioned at the 3rd pellet shot from a slingshot hole 4 is positioned at the 3rd pellet shot from a slingshot hole 4 and pellet shot from a slingshot through hole 51 simultaneously; Again because the gear effect of 6 pairs of linings of lining limited post; At this moment as rotating emergency key 7b, just can drive lock core 2 relative linings 5 rotations, the operating principle of main pellet shot from a slingshot assembly is identical with existing cylinder lock.Main pellet shot from a slingshot assembly and Emergency bomb sub-component common sparing pellet shot from a slingshot.
It circumferentially also has the second arc stopper slot 53 lining 5 perisporium upper edges; This second arc stopper slot 53 and the first arc stopper slot 52 are axially spaced apart from each other; Plug on the lock core 2 and be fixed with a lock core limited post 8; The end of this lock core limited post 8 gets into the second arc stopper slot 53 so that lock core 2 is carried out rotary spacing after passing the lock core periphery wall; Promptly before the relative linings 5 of lock core 2 rotated, this lock core limited post 8 was conflicted with an inside wall of this second arc stopper slot 53, that is to say that cooperating between this lock core limited post 8 and the second arc stopper slot 53 is that lock core 2 is carried out backward rotation is spacing; Be that lock core 2 can only be locked shell 1 relatively and on the basis of first opening angle, continues deflection forward; The radian of the second arc stopper slot 53 can be 90 degree, and in fact lock core 2 is general as long as 30 degree need not to turn to another inside wall conflict position that makes the lock core limited post 8 and the second arc stopper slot 53 on the basis of first opening angle certainly.
Like Figure 19～21,25, shown in 26; Aforementioned cylinder lock also comprises main plectrum 9 and emergent plectrum 10; Wherein, said main plectrum 9 also can rotate with lock core 2 with the inner of lock core 2 is fixing, and emergent plectrum 10 axial limitings are in relative lock core 2 deflections of inner and ability of lock core 2; The promotion post 91 that has evagination on main plectrum 9 end faces; Have on the emergent plectrum 10 and supply said promotion post 91 to insert and the arc guide groove 101 of slippage, the number of degrees of the radian of this arc guide groove 101 and the axis in the second pellet shot from a slingshot hole 3 and the 3rd pellet shot from a slingshot hole 4 number of degrees at an angle to each other are identical, are 90 to spend.
Have an irregularly-shaped hole 92 on the main plectrum 9; Accordingly; On the end face of said first installation portion 24, also have the shape of protrusion and second installation portion 25 that irregularly-shaped hole 92 matches; Have screwed hole on the end face of this second installation portion 25, main plectrum 9 is set on this second installation portion 25 through irregularly-shaped hole 91, and externally with screw 15 axial limitings that are connected with said screwed hole.
The operating principle and the process of this billiards lock structure are following:
Normal opening process: shown in Fig. 1～6, master key 3 is inserted in the master key hole 4, the teeth groove on the master key 3 is with pellet shot from a slingshot 14 jack-up in the main pellet shot from a slingshot assembly; At this moment as rotation master key 7a first interface in the interface that makes the pellet shot from a slingshot 14 in the main pellet shot from a slingshot assembly and lining 5 and the lock between the cover 11 flushes, and the pellet shot from a slingshot 14 that is positioned at lock core 2 is positioned at the first pellet shot from a slingshot hole 22 and pellet shot from a slingshot through hole 51 simultaneously; Just can drive lock core 2 and lock shell 1 rotation relatively of 5 whiles of lining, main plectrum 9 is also locked shell 1 deflection certain angle with lock core 2 relatively, when lock core 2 deflects into first opening angle; This first opening angle is 90 degree, and master key 7a roughly is in vertical position, because the inside wall of the lining limited post 6 and the first arc stopper slot 52 retaining touches; Stop lining 5 further to rotate; And lock core 2 is to link to each other through pellet shot from a slingshot with lining 5, so lock core 2 can not further rotate, the main plectrum that links to each other with lock core 2 can not further rotate; Emergent relatively plectrum 10 rotations of lock core 2 in this whole process; And the arc guide groove 101 free slippages of the promotion post 91 on main plectrum 9 end faces on emergent plectrum 10 contact with the sidewall of arc guide groove 101 until promoting post 91, so have only main plectrum 9 rotations in the normal opening process; And emergent plectrum 10 is motionless, and an inside wall of the lock core limited post 8 and the second arc stopper slot 53 is conflicted.
Emergency opening process: shown in Fig. 7～12; After lock core 2 and main plectrum 9 turn to first opening angle; Extract master key 7a and insert emergency key 7b, the teeth groove on the emergency key 7b is 14 jack-up of the pellet shot from a slingshot in the Emergency bomb sub-component, and the interface between two pellets shot from a slingshot is flushed with second interface between lock core 2 and the lining 5; And the pellet shot from a slingshot 14 that is positioned at the 3rd pellet shot from a slingshot hole 4 is positioned at the 3rd pellet shot from a slingshot hole 4 and pellet shot from a slingshot through hole 51 simultaneously; Again because at this moment the gear effect of 6 pairs of linings of lining limited post as rotating emergency key 7b, continues rotation forward just can drive lock core 2 relative linings 5; Lock core limited post 8 slippage in the second arc stopper slot 53; The main plectrum 9 that links to each other with lock core also is rotated further certain angle on the basis of first opening angle, the promotion post 91 on main plectrum 9 end faces can drive emergent plectrum 10 and on the basis of first opening angle, be rotated further certain angle with main plectrum 9 and lock core 2, finally arrives second opening angle; General 30 degree of this angle get final product, and at this moment lock core limited post 8 separates a segment distance with the inside wall of the second arc stopper slot 53.
Be reset to the normal condition process: shown in Figure 13～18, backward rotation emergency key 7b drives lock core 2 and 9 revolutions of main plectrum; The inside wall of the lock core limited post 8 on lock core and the second arc stopper slot 53 is conflicted, and promptly turns to the emergency opening state, emergent relatively plectrum 10 rotations of lock core 2 in this whole process; And the arc guide groove 101 free slippages of the promotion post 91 on main plectrum 9 end faces on emergent plectrum 10 contact with the opposite side sidewall of arc guide groove 101 until promoting post 91, extract emergency key 7b; Insert again and backward rotation master key 7a; Lock core 2 and on main plectrum 9 continue backward rotation because the promotion post 91 on main plectrum 9 end faces can drive emergent plectrum 10 with main plectrum 9 and lock core 2 revolutions, keep off until the inside wall of lining limited post 6 and the first camber line stopper slot 52 and to touch; Stop lining 5 further to rotate; Lock core 2 can not rotate again, extracts master key 7a, and main simultaneously plectrum 9 resets with emergent plectrum 10.
When this billiards lock structure is applied on the safe door; The deflection of main plectrum is the slide plate effect of playing latch locking structure on the locking security door; Promptly stop the slide plate slippage, and when emergent plectrum rotates, the electronic lock in the emergent plectrum touching strongbox; Mechanically open electronic lock, therefore have emergency function.
