Combination lock cylinder

Abstract

The invention discloses a coded lock cylinder. A code of a coded lock is set on strip-shaped code bars, the defects of an existing code-disc coded lock are overcome, the whole coded lock cylinder canbe designed to be slender-strip-shaped, and moreover, the code bars are arranged in an inner body of the lock cylinder in parallel, and play an external anti-detection role simultaneously; secondly, through the interference of anti-detection convex bars or limit ratchets which are added to the code bars of the coded lock cylinder on related shifting sheets or insertion sheets, the position of thecode cannot be detected through human sense any more, and therefore, the coded lock cylinder can be designed to form a coded lock of luggage and a common soft lock; and meanwhile, the coded lock cylinder can further be updated to be a replaceable lock cylinder for a security door, so that the application range of the coded lock cylinder is further expanded.

Description

technical field [0001] The invention relates to a mechanical combination lock cylinder, in particular to a strip-shaped combination lock cylinder whose appearance geometry is similar to that of an ordinary mechanical lock cylinder. Background technique [0002] The common elongated mechanical lock cylinder currently on the market has a lower anti-technical opening function. The setting of its password of existing mechanical combination lock is realized mostly by the combination disk of disk or ring class, and the structure that this kind of password is arranged on the disk is made into strip-shaped combination lock, and this combination disk should It is vertically connected one by one, but the anti-technical opening effect of products made of this structure is low, such as most mechanical safes and most luggage combination locks on the market. The inventor has also applied for some patents for combination locks, such as the patent for invention with the patent number 20101...

AI Technical Summary

Problems solved by technology

The inventor has also applied for some combination lock patents, such as the patent for invention with the patent number 2010102310818. The overall layout of the combination lock is horizontal, and it is difficult to design a combination lock in the shape of a longitudinal slender strip

[0003] Therefore, if the mechanical combination lock cannot be made into a slender strip, the application range of the mechanical combination lock is limited to a certain extent, especially it is not easy to make a replaceable lock cylinder like an ordinary door lock.
