Abstract

The present invention relates to a lock with a special structure. In order to overcome the shortcoming that the password operation part of the anti-theft lock in the prior art is located in the open in the long-term locked state and is easily damaged, the present invention provides an anti-theft lock. The main points of the invention are: The combination lock moves in the sleeve on the lock box through the guide rod, and the rotary disc set on the lock sleeve is connected with the operating part through the flat shift fork. The first radial plate on the outer surface of the rotary disc pushes against the At the front end of the combination lock, the second radial plate can be pushed to the control block in the control box under the front part of the sleeve, and a limiter and a limit spring are arranged in the blind hole below the inner end surface of the retaining ring connected to the sleeve. The limiter can ensure that the anti-theft lock can only be opened by the operation part when the combination lock is at the forefront.

Description

technical field [0001] The invention relates to a lock, especially a lock with a special structure. Background technique [0002] Known anti-theft locks have some to be made up of cylinder pin lock or other form of operation parts, can turn around and have the coding disc type combination lock of breach and the control part between combination lock and operation parts. The shortcoming of this anti-theft lock is: because the operating part of combination lock is exposed to the outside, in the long-term locked state, it is vulnerable to accidental damage, and because people, especially children, play with combination lock at will due to curiosity, it will also make combination lock Cause damage, and this all brings inconvenience to the user. Invention content: [0003] The purpose of the present invention is to provide a new type of anti-theft lock, when it is in the locked state, the handwheel operation part of the combination lock is hidden inside the anti-theft lock, onl...
