an anti-theft lock

Abstract

The invention relates to an anti-theft lock. A coded lock and a door lock are arranged on a fixed plate. Only when the coded lock is correct, are rectangular gaps in disks just over against rectangular bulges of connecting blocks, and at the moment, the connecting blocks can slide freely on sliding rails, a turntable can rotate with handles as long as the handles of the door lock are rotated, and convex blocks on the handles are matched with the connecting blocks, and are propped against the connecting blocks to slide on the sliding rails. Since the rectangular gaps on the disks are just over against the rectangular bulges of the connecting blocks, the connecting blocks can slide freely, without hindering the rotation of the turntable. The turntable rotates normally, so that a door is opened normally. Otherwise, the connecting blocks cannot slide, resulting in stopping the continuous rotation of the convex blocks and hindering the rotation of the turntable, so that the door is not opened.

Description

technical field [0001] The invention relates to an anti-theft lock, which is mainly used in the field of life. Background technique [0002] Existing locks, especially household door locks, are more and more secure. Since the unlocking methods of existing key locks are relatively simple, illegal unlockers only need to use tools such as steel bars to toggle the shift block on this side, and then they The purpose of illegal unlocking can be achieved, and its anti-theft performance is relatively limited. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides an anti-theft lock, which makes combination locks, door locks and key locks organically integrated, thereby improving the security of the lock. [0004] The technical scheme adopted in the present invention is: [0005] An anti-theft lock, comprising a combination lock, a door lock and a fixed plate, the combination lock and the door lock are installed...
