a combination lock

Abstract

The invention discloses a coded lock. The coded lock comprises a shell, a lock shell capable of rotating relative to the shell penetrates through the shell, a lock cylinder assembly capable of rotating relative to the lock shell is arranged in one end of the lock shell, and the other end of the lock shell is fixedly connected with a lock piece; a character wheel mandrel capable of moving leftwards and rightwards along with rotation of the lock shell is further arranged in the shell, the character wheel spindle is sleeved with a plurality of character wheel cores capable of moving along the character wheel mandrel or moving relative to the character wheel mandrel, each character wheel core is sleeved with a character wheel capable of driving the corresponding character wheel core to rotate together or moving relative to the corresponding character wheel core, and the outer surface of each character wheel is provided with a plurality of code characters. A moving plate capable of moving leftwards and rightwards along with rotation of the lock cylinder assembly is arranged in the shell, the moving plate is provided with a plurality of top cores capable of moving vertically along with horizontal movement of the moving plate, the top cores correspond to the character wheel cores in a one-to-one mode and are embedded with the character wheel cores. The coded lock has the technical advantages that codes can be retrieved conveniently through structural improvement, and the safety of the coded lock can be improved.

Description

technical field [0001] The invention relates to a mechanical combination lock. Background technique [0002] At present, the combination locks in use mainly include mechanical and electronic types. Whether it is an electronic or mechanical combination lock, it is troublesome to retrieve the password after forgetting the password. If the lock is opened violently, the combination lock is often unusable, improving costs. And the mechanical combination lock on the market at present is easy to be messed with password when opening state, and combination lock can be used normally but password is reset, and original password does not work, and the user will not be able to open lock. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a combination lock, no matter the password is forgotten or the password is messed up when it is opened, the original password can be retrieved, and...
