Cipher control device of mechanical cipher lock

Abstract

Cipher control device of mechanical cipher lock, including casing, clapboard, guide plate, supporting plate, startup board, cipher key, setting box, setting pole, drive member, startup member, setting member and block key device. The startup board is provided with conversion slice and first preformed hole; the setting box combining with the startup board; the drive member is provided in lower part of the startup board, the startup member is joggled with the drive member, one end of the setting pole is connected with the clapboard, the other end is connected with the setting member. The conversion slice includes still section and movable section. The startup board is also provided with projecting portion, a second groove and insertion hole. rim of the setting box is provided with conversion pin and on the back is provided with U-shape groove. The setting box also includes reset slice, fixed bayonet and movable bayonet. The block key device is arranged between the clapboard and the cipher key, and an arc concave position is provided in the cipher key position. many groups of ciphers can be set simultaneity, the keys are operated repeatable, setting cipher without removing lock, but need input former cipher, the cipher amount is large and security is perfect, capable of changing all kinds of locks, such as car lock and motorcycle lock, etc.

Description

technical field [0001] The invention belongs to the technical field of locks, and in particular relates to a code control device for an intelligent mechanical code lock. Background technique [0002] Combination lock is a kind of convenient and reliable lockset. In the prior art, combination locks are divided into electronic key combination locks and mechanical key combination locks. Electronic key combination locks have a large number of passwords, but are not moisture-proof, acid-proof, and waterproof. Although mechanical key combination locks can be moisture-proof, acid-proof, and waterproof, The amount of codes is far less than that of electronic key combination locks. In the prior art, although the mechanical combination lock cylinder is convenient to cooperate with the existing lockset, there are still many defects in the mechanical combination lock cylinder. In the prior art, mechanical combination locks usually only have one set of passwords, which cannot meet the ...

AI Technical Summary

Problems solved by technology

In the prior art, combination locks are divided into electronic key combination locks and mechanical key combination locks. Electronic key combination locks have a large number of passwords, but are not moisture-proof, acid-proof, and waterproof. Although mechanical key combination locks can be moisture-proof, acid-proof, and waterproof, The number of passwords is far less than that of electronic key combination locks

In the prior art, although the mechanical combination lock cylinder is convenient to cooperate with the existing lockset, there are still many defects in the mechanical combination lock cylinder.

In the prior art, mechanical combination locks can only set one set of passwords, which cannot meet the needs of different users in the same building in modern life to share a door lock and set different passwords.

In addition, in the prior art, when the mechanical password lock is in operation, the keys cannot be operated continuously, so the amount of passwords is greatly reduced.

When changing the password, it is often not necessary to enter the old password, and the lock cylinder needs to be disassembled to reset the password, so there are many discomforts in changing the password

At the same time, there are defects in the installation of mechanical combination locks such as large damage to the door and restrictions on the thickness of the door.
