Abstract

The invention discloses a lock with an idling core structure, which comprises a front core and a black core which are all in a lock body; the front core is provided with a side marble, which matches with an angle marble and is formed by a locked column and a small marble, and a sliding block, which is corresponding to the locked column; the sliding block and the locked column are respectively provided with a convex lock (a groove) and a groove (a convex block) which can match with each other; a replacing spring of the sliding block is arranged with the sliding block and the end arm of a locked column groove; on the black core, a bolt sliding groove is arranged corresponding to the locked column groove of the front core; a bolt is put into the blot sliding groove; a blot replacing spring is arranged between the end arm in the blot sliding groove and the blot; the elasticity of the blot replacing spring is larger than that of the replacing spring of the sliding block; at least one of the blot and the blocked column groove has an inclined plane and is contacted with the other at the inclined plane. The lock adopted the on-off core of the invention can successfully prevent the lock from opening by violated tools.

Description

technical field [0001] The invention belongs to mechanical locks, and relates to a lock with an idle lock core structure. Background technique [0002] In terms of locks, the tumbler lock has always been the most widely used product. Among the existing tumbler locks, there is a kind of lock that adopts a lock side column structure in which a locking side post is arranged on the lock core, and a side pin composed of small pins cooperates with an angle pin with a notch to control the opening and closing of the lock core. It solves the weakness that the traditional mechanical pin lock does not prevent technical unlocking, and its structure can be found in the ZL200610128732.4 patent document. But this lock still has the problem that it is difficult to resist destructive forceful unlocking. If you use a strong enough lockpicking tool to forcibly twist the lock cylinder, the bolt fixing the lock head can be twisted off. Contents of the invention [0003] The object of the pr...
