Plain-secret dual-coded mechanical lock

Abstract

The invention relates to a plain-secret dual-coded mechanical lock in the technical field of articles of everyday use. The plain-secret dual-coded mechanical lock comprises a cavity, a rotating gear disc, a lock cylinder, a warp plate mechanism and a pressing mechanism, wherein the cavity is formed by an upper base plate mechanism and a lower base plate mechanism, and the rotating gear disc, the lock cylinder, the warp plate mechanism and the pressing mechanism are positioned in the cavity. The lower base plate mechanism comprises three groups of lower positioning mechanisms in central symmetry and uniform distribution, and each group of lower positioning mechanisms comprises a code drive plate positioning cylinder, a warp plate positioning base, a first elastic part positioning convex hole and two retaining plates; in each group of lower positioning mechanism, the two retaining plates are arranged on two sides of the corresponding first elastic part positioning convex hole respectively and disposed between the warp plate positioning bases of two adjacent groups of lower positioning mechanisms; the wrap plate positioning bases, the first elastic part positioning convex holes and the retaining plates of the three groups of lower positioning mechanisms form a triangular structure, and the code drive plate positioning cylinders are disposed outside the triangular structure. An original single-layer code lock structure is abandoned, a second-layer code is introduced, and innovation of the coded lock principle and improvement of safety performance of the coded lock are achieved by means of introducing a logic sequence during code inputting through the second-layer code.

Description

technical field [0001] The invention relates to a lock in the technical field of daily necessities, in particular to a light and dark double-coded mechanical lock. Background technique [0002] Combination locks are suitable for most of the fields that require application locks in daily life, work and study because of their simplicity and compactness. The principle of the current dial-type combination locks is similar: the combination lock restricts the release of the lock cylinder through the combination dial, that is, unlocking. The password dial is divided into ten equal parts, corresponding to the passwords 0 to 9. There is a groove on the inner circle of the password dial, which corresponds to a number on the dial, that is, the password. When all the passwords are dialed to the predetermined position, all the grooves are arranged in a line, at this time, the lock cylinder can be released through the channel formed by the grooves to achieve the purpose of unlocking.

Problems solved by technology

However, this technology does not change the single-layer coding. People who understand the unlocking method of the lock and steal the password can still open the combination lock. Based on the security and operability of the combination lock, it is necessary to use The sequence is introduced into the code, which fundamentally innovates the unlocking mechanism of the combination lock
