an anti-theft lock

Abstract

The invention belongs to the technical field of anti-theft locks, and specifically relates to an anti-theft lock, which includes a lock body and a key; a key slot is provided inside the lock body; a connecting rod is fixedly connected above the right end of the lock cylinder; The side is fixedly connected with a tapered block; the upper surface of each said card plate is fixedly connected with the first block; the inner wall of the right side of the lock cylinder is fixedly connected with the second block; The first slider; the upper surface of the lock body is provided with a lock ring; the key is composed of a handle and a round rod; the third groove is fixedly connected with a rotating shaft by a spring; the right side of the third groove is provided with a The fourth groove; the top and bottom of the fourth groove are provided with extrusion grooves; the present invention is mainly used to solve the problem that the existing anti-theft locks always use the "resistance limit device" of the spring or tension spring forming mechanism to achieve locking Function to prevent damage by external force or use wire to hook the spring to open the lock and prevent the lock cylinder from entering water and rusting to damage the anti-theft lock.

Description

technical field [0001] The invention belongs to the technical field of anti-theft locks, in particular to an anti-theft lock. Background technique [0002] With the development of society, there are many kinds of locks on the market, and the anti-theft means adopted are also various, such as a word key, a cross key and an AB face key, etc., but the existing locks still cannot prevent thieves from using tools to pass through the key.
