Abstract

The utility model relates to an automatic locking protection anti-theft lock and a key, which consists of a lock core, an outer lock core and pin tumbler s, wherein the pin tumbler s in the lock core are arranged crosswise and correspondingly, an automatic locking device is arranged at the position close to a locking hole, the automatic locking device consists of a locking piece, a pin tumbler and a spring, the locking device is fixed on an inner lock core, the spring of the locking device is fixed on the outer lock core, and the asymmetrical misplaced pin tumbler s are arranged between the locking device and the spring. The utility model has the advantages that the structure is simple, the anti-theft performance is strong, the manufacture cost is low, and the operation is convenient.

Description

Automatically lock protection anti-theft unlocking head and key

Technical field

The utility model relates to a kind of tapered end, especially relates to a kind of protection anti-theft unlocking head and key of automatically locking.

Background technology

The tapered end that generally uses all is to adopt row's pellet shot from a slingshot and the above symmetrical pellet shot from a slingshot of two rows now, this structure is because pellet shot from a slingshot is few, arrange in order, thereby be easy to one row's pellet shot from a slingshot to be dialled the sub-hole of resilience and reach the purpose of unblanking with picklock, gap between the pellet shot from a slingshot is bigger, hard thing can directly contact pellet shot from a slingshot, and pellet shot from a slingshot is pushed open to both sides simultaneously, so its anti-theft feature is relatively poor.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, theftproof performance is strong automatically locks protection anti-theft unlocking head and key.

The technical solution of the utility model comprises: by lock core, outer lock core and pellet shot from a slingshot constitute, wherein the pellet shot from a slingshot in the lock core becomes the corresponding arrangement of intersection, lockhole is made as square groove, and be provided with automatic locking apparatus near the lockhole position, described automatic locking apparatus is by the automatic locking stator, automatic locking stator pellet shot from a slingshot and automatically lock flat spring and constitute, the automatic locking stator is fixed on the internal cylinder, automatically locking flat spring is fixed on the outer lock core, automatic locking stator and automatically lock and be provided with asymmetric dislocation pellet shot from a slingshot between the flat spring, the pellet shot from a slingshot of the rarest two the pellet shot from a slingshot correspondences when opening of the pellet shot from a slingshot in the lock core misplaces, hard thing and soft thing can't be opened, and locking plate is square.Be provided with automatic locking stator reset hole on the key, internal cylinder matches is provided with recessed lockhole screening glass reseting groove and fork-shaped tooth on the key.

Compared with prior art, advantage of the present utility model is, and is simple in structure, theftproof performance is strong, and cost of manufacture is low, and is easy to use.

The specific embodiment

Embodiment, shown in Fig. 1-7, constitute by lock core 2, outer lock core 3 and pellet shot from a slingshot 7, the wherein corresponding arrangement of 7 one-tenth intersections of the pellet shot from a slingshot in the lock core 2, lockhole 1 is made as square groove, and be provided with automatic locking apparatus near lockhole 1 position, described automatic locking apparatus is by automatic locking stator 4, automatic locking stator pellet shot from a slingshot 5 and automatically lock flat spring 6 and constitute, automatic locking stator 4 is fixed on the internal cylinder 2, automatically locking flat spring 6 is fixed on the outer lock core 3, automatic locking stator 4 and automatically lock and be provided with automatic locking stator pellet shot from a slingshot 5 between the flat spring 6, and automatic locking stator 4 is square.Key 9 is provided with automatic locking stator reset hole 8, and the key 9 that matches with internal cylinder 2 is provided with recessed lockhole screening glass reseting groove and fork-shaped tooth.

Two groups of pellets shot from a slingshot in this tapered end all are that the symmetry dislocation is arranged, the rarest two ortho position pellets shot from a slingshot are that dislocation is corresponding when opening tapered end, two pellets shot from a slingshot all exceed the keyhole center line, and the end that pellet shot from a slingshot contacts with key all has and the corresponding angle of key, and the angle of pellet shot from a slingshot has exceeded the center line of keyhole.The reset hole place of the end of key and key all has and pellet shot from a slingshot, the corresponding angle of locking plate, and key can freely be plugged in keyhole.The function that the structural arrangement of this pellet shot from a slingshot is inserted hard thing and the extruding of soft thing can't be opened.The locking plate of keyhole end is identical with the external world, when key inserts lockhole, the head of key is because of having and the corresponding angle of locking plate, locking plate can slip off from the direction of trend symmetry, tapered end is in locking states, when key was inserted into assigned address, the locking plate in the tapered end can be got back in the reset hole of key automatically, and key just can freely rotate like this.
