Abstract

The invention relates to a mechanical anti-theft lock, comprising a lock body, a lock cylinder, a pin, a keyhole, a deadbolt and a door handle rod. The lever is a front and rear two-section structure with a toggle lever, and the front and rear sections are connected as a whole through the transmission connecting sleeve (the lock cylinder slides through the movement of the lever and the transmission connection sleeve is linked, and the rear door handle is linked with the dead bolt). Fundamentally change the structure of the existing door lock cylinder; the key hole is integrated with the lock body, the key can only be inserted and cannot be rotated, and the dead bolt of the door can be opened or closed by twisting the door handle rod. The invention adopts balls to lock the lock cylinder, without external force directly acting on the lock cylinder, it is difficult to correctly identify the position of the marbles, can effectively solve the problems of technical unlocking and violent unlocking, and has good anti-theft performance.

Description

technical field [0001] The invention relates to a mechanical anti-theft lock. Background technique [0002] In the prior art, a lock is a fastener that is placed on an openable and closable object and opened with a key or a password. Various forms of locks can be seen in people's lives, and door locks are the most frequently used ones.

When unlocking, insert the key into the keyhole on the lock cylinder and turn the key to unlock. The combination of marbles and the shape of the key are constantly changing, which still cannot solve the problems of technical unlocking and violent unlocking; so the anti-theft effect is relatively poor. Contents of the invention [0003] The object of the present invention is to overcome...
