Abstract

The utility model discloses an anti-theft lock and relates to a lock core of anti-theft lock used for anti-theft doors, safety cabinets or vehicles. The utility model solves the problems that the prior lock core of anti-theft lock adopts cylindrical ball assemblies, can be unlocked in a few seconds by poking the balls with a steel wire clasp due to the fact that the ball assemblies are independent with each other, can be damaged and has bad anti-theft performance. The technical proposal of the utility model is that: two rows of wave-shaped T-shaped sheets are axially arranged in the lock core along the radial direction of the lock core, the T-shaped sheets are arranged in the lock core through a spring; both sides of the T-shaped sheets are provided with lock stopping blocks, one sides of the lock stopping blocks are arranged in a case groove of a lock core case, the other sides are dynamically connected with the T-shaped sheets; one end of a ball is arranged in the lock core through a spring, the other end is fixed with a magnet; the utility model adopts a group of T-shaped sheets to replace the ball assemblies in the lock core, the technical unlocking is to impose rotation force on the lock core, but the lock stopping blocks are locked in the case groove of the lock core and fails to rotate due to the interaction of the lock core and the lock core case, so the technical unlocking is not possible.

Description

A kind of theftproof lock

Technical field

The utility model relates to a kind of theftproof lock, relates to a kind of anti-theft lock core that is used on security door, safety cabinet, the vehicle specifically.

Background technology

The lock core of theftproof locks such as traditional cross, a word, abnormal shape is to adopt column type pellet shot from a slingshot group, all be independently between each pellet shot from a slingshot group, the principle that the lock technology of this kind structure is opened is to utilize the gap in pellet shot from a slingshot hole, applies a power of rotating to lock core, stirs each pellet shot from a slingshot with steel wire hook, make each dissection of pellet shot from a slingshot, several seconds just can open, and therefore, being locked in of this kind structure is easy under the situation that does not have key just can open with steel wire hook, and destructible, its theftproof performance is very poor.

Summary of the invention

The purpose of this utility model provides a kind of key that do not have, the theftproof lock that can't open with other instruments.

The technical solution of the utility model is: the utility model comprises lock body and lock core two parts, and along the T matrix that two row's undulates radially are housed of lock core, the T matrix is packed into by spring in the lock core in lock core; Only lock dog is housed in the both sides of T matrix,, moves with the T matrix on one side and connect one side end being contained in the outer grooving on the lock core sleeve of lock dog; Pellet shot from a slingshot one end is packed into by spring in the lock core, is fixed with a magnetic patch iron on the other end.

Said T matrix has 4 groups in the technical solutions of the utility model, is cross arrangement and packs in the lock core, and the last plane of each T matrix is an arc, has the V-type groove on the vertical edge.

Be provided with spring stop piece between said spring and the lock core sleeve in the technical solutions of the utility model.

The said lock dog that ends is contained in the outer grooving of lock core sleeve on axially in the technical solutions of the utility model, have on it with lock core sleeve on the corresponding magnetic patch of magnet.

Said pellet shot from a slingshot is contained in the radial hole of T matrix front end lock core in the technical solutions of the utility model.

Because being one group of T matrix of employing, the utility model replaces the pellet shot from a slingshot group in the known lock core, its technical opening is to apply commentaries on classics power to lock core, because the interaction of lock core and lock core sleeve ends lock dog and is stuck in the lock core sleeve groove and can't moves, it is impossible that the stock trick art is opened; In addition, lock core of the present utility model can rotate arbitrarily angled; According to the structure that need change the utility model lock core sleeve, lock core of the present utility model can be installed on the lock body on security door, safety cabinet or the vehicle etc.

The specific embodiment

Shown in Fig. 1,2,3,4, in lock core 1, the T matrix 3 that two row's undulate shapes radially are housed along lock core 1, T matrix 3 is provided with 4 groups, per two T matrix 3 are cross arrangement and pack in the lock core 1, the last plane of each T matrix 3 is an arc, after arranging, 4 groups of T matrix 3 make its upper surface undulate shape, as shown in Figure 1, all have V-type groove 15 on the vertical edge of each T matrix 3, as shown in Figure 2, packing into by spring 12 in the lock core 1 in the vertical edge bottom of T matrix 3, is provided with spring stop piece 10 between spring 12 and the lock core sleeve 4; Only lock dog 11 is housed between T matrix 3 both sides and lock core sleeve 4, only the shape of lock dog 11 as shown in Figure 3, article one, the limit is the conical surface, be fixed with magnet 13 on the opposite side on conical surface limit, ending lock dog 11 is contained in the outer grooving 8 of lock core sleeve 4 on axially, magnet 13 on it is corresponding with the magnet 2 on the lock core sleeve 8, ends the conical surface limit of lock dog 11 and 15 moving connections of vertical edge V-type groove of T matrix 3; The hole that radially is provided with installation pellet shot from a slingshot 7 along lock core 1, this hole is located at the front end of T matrix 3, on the center line of T matrix 3, parallel with the vertical edge of T matrix 3, an end of pellet shot from a slingshot 7 is thick, and an end is thin, a thick end is contained in the hole on the lock core 1 by spring 9, be clipped in two and end between the lock dog 11, be separated by by spring stop piece 10 between spring 9 and the lock core sleeve 4, be fixed with a magnet 6 on the thin end of pellet shot from a slingshot 7; Front end at lock core 1 is equipped with brace 5, and brace 5 inserts in the lock body of theftproof locks such as security door, safety cabinet, vehicle; Front end at lock core 1 is fixed with jump ring 14, and jump ring 14 is installed in the groove of lock core 1 front end; Key of the present utility model adopts double wave tooth 17, as shown in Figure 4, promptly with lock core 1 on the T matrix 3 of two row's undulate shapes match, be fixed with a magnetic patch 16 on the front end of key, this magnetic patch is corresponding with the magnetic patch 6 on the pellet shot from a slingshot 7, when key inserts lockhole, T matrix 3 overcomes the elastic force of spring 12, corresponding to the depth of each wave tooth on the key, make it to coincide mutually, the V-type groove 17 of each T matrix 3 all in a straight line, simultaneously, the magnetic patch of key front end 16 repels corresponding magnet 6, pellet shot from a slingshot 7 butt ends are moved down, T matrix 3 both sides end the repulsion that lock dog 11 is subjected to the magnet 2 on the lock core sleeve 4, break away from outer grooving 8 and enter V-type groove 15 on the T matrix 3, key can be finished and unblank.
