Description

Compound cylinder lock

Technical field

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

Background technology

Chinese patent on April 5th, 2000 disclosed a kind of side column inner pressed antitheft sylinder, the patent No. is 99233344.X, this kind cylinder lock utilizes cooperating of clamping block and pellet shot from a slingshot, and the mobile control lock core by clamping block rotates relative to lock body, and its advantage is that anti-technical opening performance is good; But owing to lock by clamping block between the lock core of this cylinder lock and the lock body, and the distance that clamping block moves depends on the V-type groove depth of pellet shot from a slingshot, because billiards diameter is fixed, the V-type groove depth just can not be dark excessively, therefore locking is also just unreliable between lock core and the lock body, causes this cylinder lock theftproof performance undesirable.

Summary of the invention

In order to overcome the above-mentioned disadvantage that existing cylinder lock exists, the utility model provide a kind of simple and reasonable, open flexibly, mutual opening rate is low, anti-technical opening and the good cylinder lock of theftproof performance.The technical scheme that its technical problem that solves the utility model adopts, comprise lock body, lock core, the V-type pellet shot from a slingshot, marble pressuring spring, clamping block and key, lock core is provided with one group of pellet shot from a slingshot hole that V-type pellet shot from a slingshot and marble pressuring spring are installed, lock core is provided with lock slots vertical with the pellet shot from a slingshot hole and that communicate with lock body, clamping block is arranged in the lock slots, the step of clamping block both sides is provided with locking spring and locking mounting, the locking mounting is fixed on the lock core, the wedge angle of clamping block matches with V-type groove on the V-type pellet shot from a slingshot, at least be provided with one group of pellet shot from a slingshot through hole on described lock body and the lock core, be provided with down pellet shot from a slingshot on the pellet shot from a slingshot through hole successively, last pellet shot from a slingshot, marble spring, the pellet shot from a slingshot through hole is by the pellet shot from a slingshot capping of sealing up a door, and the V-type pellet shot from a slingshot is corresponding with key tooth flower with following pellet shot from a slingshot.

After adopting said structure, upper and lower pellet shot from a slingshot is under the promotion of marble spring, following pellet shot from a slingshot enters in the keyhole, last pellet shot from a slingshot is between lock body and the lock core and locks lock core, and clamping block overcomes the elastic force of locking spring under the compressing of V-type pellet shot from a slingshot, clamping block moves on in the lock slots of lock body in the lock slots of lock core, lock core is stuck, make the existing locking of going up pellet shot from a slingshot of the utility model that the double locking of clamping block be arranged again, theftproof performance is significantly improved; Have simple and reasonable, open flexibly, advantage such as mutual opening rate is low, antitheft and anti-technical opening performance is good.

The specific embodiment

Fig. 1 is to shown in Figure 6, specific embodiments for the compound cylinder lock of the utility model, it comprises lock body 1, lock core 2, V-type pellet shot from a slingshot 7, marble pressuring spring 9, clamping block 3 and key 9, lock core 2 is provided with one group of pellet shot from a slingshot hole that V-type pellet shot from a slingshot 7 and marble pressuring spring 9 are installed, lock core 2 is provided with lock slots 4 vertical with the pellet shot from a slingshot hole and that communicate with lock body 1, clamping block 3 is arranged in the lock slots 4, the step of clamping block 5 both sides is provided with locking spring 16 and locking mounting 17, locking mounting 17 is fixed on the lock core 2, the wedge angle 5 of clamping block 3 matches with V-type groove 8 on the V-type pellet shot from a slingshot 7, lock core 2 is provided with jump ring 15, guarantee that lock core 2 cooperates with lock body 1, described lock body 1 and lock core 2 are provided with one group of pellet shot from a slingshot through hole, be provided with down pellet shot from a slingshot 11 on the pellet shot from a slingshot through hole successively, last pellet shot from a slingshot 12, marble spring 13, the pellet shot from a slingshot through hole is by pellet shot from a slingshot 14 cappings of sealing up a door, and V-type pellet shot from a slingshot 7 is corresponding with key tooth flower with following pellet shot from a slingshot 11.

The course of work of the present utility model is as follows, when key 6 inserts keyhole, when cylinder lock is in unlocking condition, as shown in Figure 1 to Figure 3, key 6 overcomes and holds up V-type pellet shot from a slingshot 7 and pellet shot from a slingshot 12 up and down behind the elastic force of marble pressuring spring 9 and
