Abstract
The utility model relates to a pin tumbler lock sealed at two sides. The lock holes in the lock core are divided into two parts. Wherein, an inner lock hole has smaller width and is located at inner side corresponding to the tooth-shaped part of a key. In addition, an outer lock hole with bigger width is located at outer side corresponding to the part of a key without teeth. At middle and cross direction of the outer lock hole, a lock core latch hole is provided with width bigger than the inner lock hole. On the lock body and at a point corresponding to the lock core latch hole, a hole for inserting the lock core latch is provided. In the lock core latch hole, a lock core latch is provided. The two sides of the top of the latch are beveled. In the hole for inserting the lock core latch, an ejecting and pushing block and a spring are provided.

Description
Technical field
The utility model relates to a kind of cylinder lock, can prevent that especially experienced robber from utilizing master key or crotch steel wire to unblank, and is the splendid two side sealed pin tumbler lock of theftproof performance.
Background technology
At present, the lock core hole of known cylinder lock all exposes, and experienced robber can insert master key or the crotch steel wire is unblanked, and lacks the sense of security.
Summary of the invention
In order to overcome the deficiency that existing cylinder lock can be opened with master key or crotch steel wire.The utility model provides a kind of two side sealed pin tumbler lock, it is when latched position, the lock core door bolt is with the whole shutoff of interior lockhole, when inserting the unlocking tool of master key or crotch steel wire and so on, then must earlier the lock core door bolt be removed a segment distance just has living space and can insert, the other end that this moment, lock core was fastened with a bolt or latch just injects the interior segment distance of lock core door bolt patchhole of lock body, and lock core can't be rotated by the shutoff locking, and is also of no avail even if whole pellets shot from a slingshot up and down of cylinder lock all reach opening.This lock must have one by shutoff no matter be in its lockhole of which kind of state and lock core between the two, so do not use hole key in the special band of this patent, any unlocking tool that don't work all can't be opened this lock.
The technical scheme that its technical problem that solves the utility model adopts is: the lockhole in the lock core is divided into two parts, be positioned at the less lockhole of inner and the corresponding width dimensions of shaped as key bit part and be positioned at the outer end, and also be provided with the lock core bolt hole of width greater than interior lockhole in the lateral attitude of exterior lockhole centre with the key stage casing does not have the bigger exterior lockhole of the corresponding width dimensions of profile of tooth part; Be provided with lock core door bolt patchhole with the lock body of lock core bolt hole opposite position.Be provided with the lock core door bolt in lock core bolt hole, the both sides, top of door bolt are provided with the inclined-plane; In lock core door bolt patchhole, be provided with push block and spring.When this lock is in initial latched position, the lock core door bolt all inserts in the lock core, the less interior lockhole of the inner size of lock core all is blocked, when inserting the unlocking tool of master key or crotch steel wire and so on, then must earlier the lock core door bolt be removed a segment distance just has living space and can insert, this moment, the other end of lock core door bolt just injected lock core door bolt in the lock body segment distance that inserts in the hole, and the lock core locking can't be rotated, and did not also have and helped and thing even if whole pellets shot from a slingshot up and down of cylinder lock all reach opening.Open this lock and must use hole key in the band, it is narrower that this key leading portion contains parts of tooth, and be provided with the inclined-plane in the top side; This key stage casing does not have profile of tooth part broad, and the centre is provided with and can bores a hole for the key stage casing that the lock core door bolt passes, and is provided with the inclined-plane in the inner of stage casing perforation.During unlatching will with in hole key when inserting the exterior lockhole of lock core outer end, the inclined-plane, the outside on lock core door bolt top is removed under key top rake face pushing tow, make key can be inserted into the end always, this moment, the lock core door bolt was just in time aimed in the perforation of key stage casing, under matching situation, removed shaped as key bit the locking of pellet shot from a slingshot up and down again, lock core can freely be rotated, reach and open this lock.
The beneficial effects of the utility model are: thoroughly stopped to utilize the unlocking tool of master key or crotch steel wire and so on to open this lock, theftproof performance is good, and simple and reliable for structure.
