Password lock

Abstract

The invention discloses a password lock. The password lock is characterized in that a lock pin is designed to move in the radial direction of password wheels to achieve password alignment, and during password alignment, rotating shafts of the password wheels do not bend and deform, so that the service life of the lock is prolonged, and the flexibility of the password wheels during rotation is improved; stop pins and stop grooves are matched to limit rotation of the password wheels and prevent people from acquiring the password through a mechanical alignment method, and the phenomenon of password losing is avoided; besides, the lock further has a password disordering function in the opening state, and password safety is better protected; and the lock is simple in designed structure, reliable in safety performance and relatively high in decoding difficulty.

Description

technical field [0001] The invention belongs to mechanical locks, in particular to a mechanical combination lock. Background technique [0002] In daily life, in order to improve the anti-theft performance of the mechanical lock, a password mechanism is often set in the mechanical lock, and the lock can be opened mechanically only after the password is entered correctly. [0003] The mechanical mechanism adopted by the existing mechanical combination lock code has the serious deficiency that it can be opened by technology. There are two existing means of cracking the secret of mechanical coded locks: the first one is to know by scanning the internal mechanism of the lock; Between the password wheel and the lock pin, a matching password groove and a password pin are set, the password groove rotates together with the password wheel, and the password pin moves together with the lock pin, and when the password groove is facing the password pin, the lock pin can move in place A...

Problems solved by technology

[0005] An object of the present invention is to provide a mechanical combination lock that can prevent the mechanical comparison method from being unlocked and will not cause password loss, so as to solve the problem that the mechanical comparison method is not effective and does not affect the normal use of the lock. problem solving method

[0006] Another object of the present invention is to provide a combination lock, which can rotate the combination input mechanism to control the combination wheel to perform random password behavior after opening, so as to solve the problem of password security
