Description
Technical field
The present invention relates to field of lockset, particularly relate to the assembly of a kind of theft proof padlock and key.
Background technology
In daily life, lockset is the important tool for protecting people's property safety.Padlock is one relatively conventional in lockset, is widely used in the places such as drawer, door, bicycle, and therefore, the theftproof performance of padlock is particularly valued by people.In the padlock of prior art, key only has only to reach, with lock core sub-component of being hit by a bullet, the purpose that just can reach to unblank that matches, so, by unlocking tools such as Unlocking gun, steel disc, screwdrivers, straight cutting enters keyhole and is easy for stirring and even destroys the pellet in lock core, the most just by force lock can be opened, cause its theftproof performance poor.
Summary of the invention
The technical problem to be solved is: provide the assembly of the preferable theft proof padlock of a kind of anti-theft effect and key.
The technical solution adopted in the present invention is: a kind of theft proof padlock and the assembly of key, including key and padlock, described key includes the shank of the key and key body, the tow sides of described key body are equipped with string pellet shrinkage pool along its length, and double-edged string pellet shrinkage pool is symmetrical arranged along the face residing for key body；
Described padlock includes lock body, lock core, lock ring, dead bolt and opens locking device, described lock ring is U-shaped, and in described lock body, it is provided with the first hole stretched into for lock ring one end, and it is provided with the first stage clip in described first hole, described first stage clip one end offsets bottom the first hole, and the end face that the described first stage clip other end and lock ring stretch into first one end, hole offsets；And described first stage clip stretches into and is additionally provided with annular groove on the outer wall of first one end, hole, the hole wall in described first hole is provided with for stretching into annular groove and then the alignment pin of location lock ring；The second hole slided for dead bolt it is provided with in described lock body, described dead bolt is arranged in the second hole, and it being additionally provided with the second stage clip in described second hole, described second stage clip one end offsets bottom the second hole, and the described second stage clip other end offsets away from lock ring one end end face with dead bolt；It is additionally provided with the 3rd hole stretched into for the lock ring other end on described lock body, and described lock ring stretches into and is additionally provided with the locking hole stretching into and then locking lock ring for dead bolt on the outer wall of the 3rd one end, hole；The degree of depth in described 3rd hole is less than the height of annular groove；
The 4th hole installed for lock core it is additionally provided with on described lock body, described lock core is arranged in the 4th hole, and described lock core includes plug body, lock core afterbody and lock core head, described plug body includes the first lock core body set gradually, first connector, second lock core body, second connector and the 3rd lock core body, described lock core head, first lock core body, first connector, second lock core body, second connector, the first keyhole of same shape it is provided with the most vertically on 3rd lock core body and lock core afterbody, described first lock core body, it is equipped with, on second lock core body and the 3rd lock core body, the pellet assembly matched with the pellet shrinkage pool on key body；The elastic connecting device for rotating reset it is equipped with on described first connector and the second connector, described elastic connecting device includes extension spring, the upper alignment pin that extension spring one end is fixed on the preceding paragraph lock core and the extension spring other end is fixed on the lower alignment pin of next section of lock core, and is additionally provided with the arcuate groove of extension spring for the extension spring and extended state housing normal condition on described first connector and the second connector；The equal separated time of the first keyhole width that equal separated time is the first lock core body of the first keyhole width on described first connector and the second lock core body is rotated in the clockwise direction 90 °, the equal separated time rotate in an anti-clockwise direction 90 ° of the first keyhole width that equal separated time is the first lock core body of the first keyhole width of described second connector and the 3rd lock core body；
Described open locking device include with lock core afterbody coaxial line for rotate extruding the second stage clip open lock, described lock body is provided with for opening the 5th hole that lock is installed, described 5th hole connects with the 4th hole, the described lock that opens is arranged in the 5th hole, open lock described in and away from being provided with gap between second stage clip one end and lock core afterbody, and described in open to be additionally provided with on lock to insert for key body and then drive and open the second keyhole that lock rotates.
Above structure prior art is used to compare, the invention have the advantages that and first lock core is arranged to syllogic, need to be rotated by a key insertion part to be inserted into the last form that just can be inserted into lock core afterbody of part rotation, and key can't open padlock after being inserted into lock core afterbody, also need to key continue into open lock in just can open padlock, i.e. in key lock core to be inserted into, also to drive and open lock rotation, finally can be only achieved the purpose unblanked, so one, for the padlock of prior art, the more safety of the padlock of the application, the most only by by Unlocking gun, steel disc, the unlocking tools such as screwdriver, stir and even destroy the pellet in lock core, although can be inserted into smoothly in lock core afterbody, but the cooperation opening lock cannot be driven, it is unable to reach the purpose unblanked；And because the degree of depth in the 3rd hole is less than the height of annular groove, so when alignment pin moves to lower end from the upper end of annular groove, the other end of lock ring can depart from completely from the 3rd hole, it is achieved that the state unblanked.
As preferably, described in open lock in be provided with for matching with the pellet shrinkage pool of key body head and then clamping the clamping element of key body head.One clamping element is set, such key and open and cooperate the most more preferably between lock so that key be inserted into open in lock after can more easily drive and open lock and rotate, reach to open the purpose of padlock.
As preferably, described in open on lock circumference and be provided with between the 5th hole hole wall for limiting the collar opening lock horizontal jitter.So arrange can prevent key drive open lock rotate time, open lock will not horizontal jitter, effect of so unblanking is preferable.
As preferably, described lock body is provided with the safety head for covering lock core, and is additionally provided with deception lock core on described lock body, and the shape of keyhole on described deception lock core and the first keyhole is identical.So arrange, as long as lock core being covered with safety head, so ordinary people just can only see the keyhole leakage of deception lock core outside, i.e. ordinary people will be considered that this deception lock core is only genuine lock core, then trial will be gone to open deception lock core unblank, thus open not padlock so that the anti-theft effect of padlock is more preferable.
