Description

The cylinder lock of multiple locking

Technical field

The utility model relates to a kind of lockset, particularly a kind of cylinder lock.

Background technology

Existing cylinder lock often solves by the means that increase the secret key amount in order to reduce mutual opening rate, and difficulty of processing is big, reduction production efficiency though can increase like this, can solve the high problem of cylinder lock mutual opening rate effectively; Yet another problem that cylinder lock exists: anti-technical opening poor performance is not resolved all the time.For this reason, many producers, research unit and individual have carried out repetition test and research, and good solution is not arranged so far.

Summary of the invention

In order to overcome the above-mentioned disadvantage that existing cylinder lock exists, the utility model provides a kind of compact conformation, opens the cylinder lock of the multiple locking flexible, that mutual opening rate is low, anti-technical opening performance is good.The technical scheme that its technical problem that solves the utility model adopts, comprise lock body, lock core, last pellet shot from a slingshot, following pellet shot from a slingshot, marble pressuring spring, key, the pellet shot from a slingshot hole is by the pellet shot from a slingshot sealing of sealing up a door, following pellet shot from a slingshot and key taper fit, described pellet shot from a slingshot down is provided with the V-type groove, lock core and lock body are provided with the lock slots that is complementary, lock slots is vertical with the pellet shot from a slingshot hole and communicate, be provided with clamping block in the lock slots, the wedge angle of clamping block inboard matches with V-type groove on the following pellet shot from a slingshot, the clamping block both sides are provided with locking spring and locking mounting, and the locking mounting is fixed on the lock core.

In order to guarantee the smooth realization of anti-technical opening performance, the fit clearance of described clamping block and lock body greater than about the fit clearance in pellet shot from a slingshot and pellet shot from a slingshot hole; The compressive force of described marble pressuring spring is greater than the compressive force of locking spring.

After adopting said structure, the corresponding pellet shot from a slingshot up and down that holds up of key when key inserts lock core keyhole, make the V-type groove on the pellet shot from a slingshot down be in same plane, and promote to go up pellet shot from a slingshot and enter in the pellet shot from a slingshot hole of lock body and break away from lock core, simultaneously, clamping block is under the promotion of locking spring, its wedge angle inserts the V-type groove, and clamping block enters lock core and breaks away from lock body, at this moment, key can be opened cylinder lock, makes the existing pellet shot from a slingshot locking of cylinder lock that the clamping block locking be arranged again; Have advantages such as compact conformation is reasonable, unlatching is flexible, mutual opening rate is low, anti-technical opening performance is good, theftproof is good.

The specific embodiment

Fig. 1 is to shown in Figure 6, specific embodiments for the cylinder lock of the multiple locking of the utility model, it comprises lock body 1, lock core 2, last pellet shot from a slingshot 8, following pellet shot from a slingshot 9, marble pressuring spring 7, key 11, the pellet shot from a slingshot hole by pellet shot from a slingshot seal up a door 6 the sealing, following pellet shot from a slingshot 9 and key 11 taper fit, lock core 2 is provided with jump ring 14, guarantee that lock core 2 cooperates with lock body 1, described pellet shot from a slingshot 9 down is provided with the V-type groove, lock core 2 and lock body 1 are provided with the lock slots 4 that is complementary, lock slots 4 is vertical with the pellet shot from a slingshot hole and communicate, be provided with clamping block 5 in the lock slots 4, the wedge angle 5 of clamping block 5 inboards matches with V-type groove on the following pellet shot from a slingshot 9, and clamping block 5 both sides are provided with locking spring 12 and locking mounting 13, and locking mounting 13 is fixed on the lock core 2.The fit clearance of described clamping block 5 and lock body 1 is greater than the fit clearance with the pellet shot from a slingshot hole of pellet shot from a slingshot 8,9 up and down, and the compressive force of described marble pressuring spring 7 can reach the purpose of preventing technical opening greater than the compressive force of locking spring 12.

The course of work of the present utility model is as follows, when key 11 inserts keyhole, when cylinder lock is in unlocking condition, as shown in Figure 1 to Figure 3, key 11 overcomes the corresponding pellet shot from a slingshot 8 up and down that holds up behind the elastic force of marble pressuring spring 7,9, V-type groove under making on the pellet shot from a slingshot 9 is in same plane, and promote to go up pellet shot from a slingshot 8 and enter in the pellet shot from a slingshot hole of lock body 1 and break away from lock core 2, the locking of 8 pairs of lock cores 2 of pellet shot from a slingshot in the releasing, meanwhile, clamping block 3 is under the promotion of locking spring 12, its wedge angle 5 inserts the V-type groove, clamping block 3 enters lock core 2 and breaks away from lock body 1, the locking of the 3 pairs of lock bodies 1 of piece that unlock, and this moment, key 11 can be opened cylinder lock.When transfering to key 11 back cylinder locks to be in locking states, as shown in Figs. 4-6, pellet shot from a slingshot 8,9 is under the promotion of marble pressuring spring 7 up and down, following pellet shot from a slingshot 9 enters in the keyhole, and last pellet shot from a slingshot 8 is on the pellet shot from a slingshot hole between lock body 1 and the lock core 2, meanwhile, clamping block 5 is under the compressing of following pellet shot from a slingshot 9, overcome the elastic force of locking spring 12, clamping block 5 moves on in the lock slots 4 of lock body 1 in the lock slots 4 of lock core 2, and lock core 2 is stuck.The utility model is owing to there is the double locking of last pellet shot from a slingshot 8 and clamping block 5, and theftproof and anti-technical opening performance are significantly improved.
