Specific implementation mode
Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings：It is a kind of referring to Fig. 1 to Fig. 2
Electronic safety lock, general doorframe 1 coordinate with door-plate 2, and lock core and lock tongue are installed respectively on doorframe 1 and door-plate 2.This electronic security(ELSEC)
Lock also needs mating lock tongue, and lock tongue is mounted on the side wall of door-plate 2, is selected in the present embodiment and is suitable for the spreader that latch hook is caught on
Shape lock tongue 3.Doorframe lock chamber is set on doorframe 1, includes in doorframe lock chamber：Electromagnet 4, rack 5, gear shaft 6, latch hook 7, it is horizontal insert
Pin 8 and perpendicular bolt 9.Latch hook 7 is fixed on by the hinge joint in the middle part of it in doorframe lock chamber, and the front end of latch hook 7 is triggered upwards, end
End is acted on by resilient support on doorframe lock chamber.Resilient support selects the first spring 10 in the present embodiment, when latch hook 7 is first
When being flicked downwards under 10 force effect of spring, triggering can be flipped up, and to catch on horizontal cylindrical bolt 3, and latch hook 7 overcomes elasticity
When power is compressed upwards, trigger to downwardly turn over being detached from horizontal cylindrical bolt 3.
The flip-flop movement of the latch hook 7 is realized jointly by the first spring 10 and electromagnet 4, is provided in doorframe lock intracavitary perpendicular
Directly flexible electromagnet 4, the push rod of electromagnet 4 are equipped with the second spring 11 for providing retentivity, and electromagnet 4 is powered, push rod gram
The retentivity for taking second spring 11 is shunk, and electromagnet 4 powers off, and push rod stretches out in the case where keeping force effect and in stroke terminal holding position
It sets.Limiting plate 13 is set on the push rod of electromagnet 4, and limiting plate 3 jacks up the end of latch hook 7 perpendicular to push rod when limiting plate 13 rises
It holds and it is made to compress the first spring 10.
The rack 5 of vertical direction is fixed on the push rod of electromagnet 4, rack 5 is pushed vertically by push rod.5 side of rack is set
It is equipped with gear shaft 6, a spur gear 25, rack 5 and 25 engaged transmission of spur gear are set on gear shaft 6.The both ends of gear shaft 6 are logical
It crosses bearing part to be fixed on pillar 14, pillar perpendicular 14 is directly supported in doorframe lock intracavitary.
One sleeve 15 perpendicular to gear shaft axis is set on one end end face of gear shaft 6, unification root is matched in sleeve 15
Connecting rod 16.The outer of the upper end setting limit of connecting rod 16 skids off sleeve 15 when avoiding with movement, and the lower end of connecting rod 16 is equipped with hinged
First 17, spring is set between articulated joint 17 and sleeve 15, and the spring in the present embodiment herein is third spring 18.Articulated joint 17 is lived
Dynamic horizontal bolt 8, horizontal bolt 8 and the coaxial package of being connected on a horizontal guide rod 19, and guide rod 19 by guide sleeve 20 with unification
Vertical guide post 21.When gear shaft 6 rotates, connecting rod 16 hauls guide rod 19 while vertical lifting on guide post 21, also can
Pull the horizontal bolt 8 on guide rod 19 flexible along guide rod 19.Changed according to the vertical range between gear shaft 6 and guide rod 19, the
Three springs, 18 deformation degree and vertical range are proportional, and horizontal bolt 8, third spring 18 can be retracted when being compressed to third spring 18
Horizontal bolt 8 can be released when flicking.The operating position of horizontal bolt 8 is set, when the rotation of gear shaft 6 makes third spring 18 push
Horizontal bolt 8 to the end of guide rod 19, guide rod 19 simultaneously slides into 21 lowest positions of guide post, and horizontal bolt 8 stretches out doorframe lock chamber；Gear
Axis 6 turns round, and guide rod 19 slides into the middle part of guide post 21, and horizontal bolt 8 then bounces back certain size.The front end of horizontal bolt 8 is equipped with jag,
The width of jag is more than the diameter of horizontal latch body.The side wall of doorframe lock chamber is equipped with the T-slot for coordinating horizontal bolt front end, because
This also is provided with corresponding T-slot on the corresponding door-plate side wall of doorframe.Horizontal bolt 8 enters from the heavy caliber of T-slot bottom, with
While horizontal bolt 8 moves up and bounce back, horizontal bolt 8 will be caught in T-slot top it is small-bore in play the role of locking.
The other end of gear shaft 6 is equipped with eccentric wheel 22, erects bolt 9 and is fixed vertically by conduit 23, conduit 23 is fixed on door
Frame locks intracavitary, and the through-hole that bolt 9 is erected in cooperation is equipped on the bottom plate of doorframe lock chamber.The 4th spring 24 of suit on perpendicular bolt 9, the 4th
Spring 24 acts between perpendicular bolt 9 and the bottom plate of doorframe lock chamber.And the upper end for erecting bolt 9 passes through one piece of driver plate 12 and bias
22 tangent cooperations are taken turns, when eccentric wheel 22 jacks up driver plate 12, perpendicular bolt 9 is then pulled up the 4th spring 24, erects 9 retraction door of bolt
Frame locks chamber；When eccentric wheel 22 falls driver plate 12, perpendicular bolt 9 stretches out doorframe lock chamber under the stretching of the 4th spring 24.
The working condition of above structure：Electromagnet 4 is powered on down, and push rod overcomes elastic force to bounce back, on limiting plate 13
It rises.Rack 5 rises and is rotated forward with movable gear shaft 6, and guide rod 19 is snapped down to 21 lower end of guide post, and horizontal bolt 8 is slided while moving down
It moves to the end of guide rod 19.Eccentric wheel 22 jacks up driver plate 12, erects 9 retraction doorframe lock chamber of bolt.
Electromagnet 4 powers off, and push rod stretches out under elastic force retentivity, and limiting plate 13 declines.Rack 5 extends downwardly band moving teeth
Wheel shaft 6 rotates backward, and 21 middle part of guide post, back shrinkage while horizontal bolt 8 moves up are slided on guide rod 19.Eccentric wheel 22 falls biography
Movable plate 12 erects bolt 9 and stretches out doorframe lock chamber.
But what can be paid attention to further includes the range of electromagnet 4, the biography of rack 5 and spur gear 25 in this structure
Dynamic length of action, the rotational angle of eccentric wheel 22 and connecting rod 16, it is same with perpendicular bolt 9 that these data constitute latch hook, horizontal bolt 8
Step degree.The range of electromagnet 4 is determined according to the size of lock chamber in general this programme, and rack 5 and spur gear 25 are nibbled
Close length be subject to spur gear 25 rotate 180 degree, specifically with 25 a diameter of reference of spur gear.And the pass of connecting rod 16 and eccentric wheel 22
System is subject in specific installation process and debugs, it is ensured that electromagnet 4 powers off under retentivity state, and horizontal bolt 8, perpendicular bolt 9 are located at lock
Only state.Conversely, under electromagnet 4 is powered, three locking modes are in retracted mode.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
