Mechanical coded lock capable of automatically searching codes

Abstract

The invention relates to a mechanical coded lock capable of automatically searching the codes. The mechanical coded lock comprises a shell, a lock cylinder assembly capable of rotating relative to the shell is arranged on the shell in a penetrating mode, and one end of the lock cylinder assembly is connected with a lock plate; a password wheel assembly is further arranged in the shell, a code searching mechanism is arranged between the lock cylinder assembly and the password wheel assembly, and when a password is forgotten, the lock cylinder assembly drives the code searching mechanism to perform code searching for unlocking; the code searching mechanism comprises a driving piece connected to the lock cylinder assembly, a code searching key and a code matching wheel; and the driving piece pushes the code searching key when moving, the pawl on the code searching key makes contact with the code matching wheel when rotating, the code matching wheel is rotated to a correct code point, and automatic code searching is achieved. The mechanical coded lock has the beneficial effects that a new mechanical structure is adopted, the Archimedes spiral principle is used for achieving automatic code searching, automatic code searching can be conducted and accurate numbers can be displayed under the condition that the character wheels are disorderly dialed, the operation is easy, a user can conveniently search codes after forgetting passwords under any condition, and the practicability is high.

Description

technical field [0001] The invention relates to a combination lock. Background technique [0002] In order to ensure personal privacy and personal property safety, people generally lock suitcases or cabinets at home. Existing locks are generally divided into two types, one is a traditional key lock, which is unlocked by a key and a lock cylinder, and the other is a traditional key lock. The second type is combination lock, which is generally based on the dial combination lock, and there are also digital key combination locks. [0003] Existing dial combination lock, can open lockset when dialing to preset password, open box door or cabinet door. But when using combination locks on some cabinets that are not often opened, it is easy to forget the password or misremember the password usually, and at this moment, it is impossible to unlock smoothly, which causes certain inconvenience to the user. [0004] Existing combination locks usually also have a code-finding structure, ...

AI Technical Summary

Problems solved by technology

However, when using combination locks on some infrequently opened cabinets, it is usually easy to forget the password or misremember the password. At this time, the lock cannot be successfully unlocked, which causes some inconvenience to the user.

[0004] Existing combination locks usually also have a code-finding structure, but the existing code-seeking structure usually performs code-finding when the lock has been unlocked, and cannot perform code-finding when the lock is closed, which also makes the code-finding of the combination lock difficult. There are certain limitations
