Problems solved by technology

[0003] Ordinary mechanical locks are cheap to manufacture and are the most widely used, but their security is poor, the key is easy to be copied, the key is thick and heavy, and it is inconvenient to carry it around when going out
In addition, when a mechanical lock (such as a door lock) needs to be replaced, it is usually necessary to replace the whole or replace the lock cylinder, which is troublesome.
[0004] Password mechanical lock does not need to wear a key, but you must remember the password. Nowadays, people have too many passwords to remember, which is easy to confuse
[0005] The security of the electronic lock is higher than that of the mechanical lock, but it needs to design a special decoding circuit. The manufacture of the lock is more complicated and the cost is also high. Due to the use of large-scale integrated circuits, it is prone to failure

Abstract

The invention relates to a mechanical lock, and provides a password switching device for a lockset. The password switching device for the lockset comprises a password block and a bore card, wherein the bore card is a rectangular thin plate with multiple card holes; the password block comprises a rectangular base, a sliding block and a lock pin; a sliding block grid is arranged in the base; the sliding block is arranged in the sliding block grid; a card groove is formed in the bottom part of the sliding block; the movable lock pin is arranged at the front end of the sliding block; a card inserting port is formed in the position, corresponding to the card groove, on the back part of the base; a lock pin port is formed in the position, corresponding to the lock pin, on the back part of the base; multiple tumbler pairs are distributed in the base and the sliding block; the bore card is inserted into the card groove; and if the all card holes are matched with the tumbler pairs, the slidingblock can drive the lock pin to retract into the rectangular base. A lock cylinder device adopting the password switching device comprises a lock cylinder and a password block, wherein a drive rod groove is formed in the front end part of the lock cylinder; a rectangular password block groove and a spring groove are formed in the lock cylinder; a spring is arranged in the spring groove; the password block is arranged in the password block groove; and the lock cylinder is horizontally provided with a lock pin bayonet and a lock pin clamping groove corresponding to the lock pin of the password block. The password switching device for the lockset, and the lock cylinder device provided by the invention have the substantive characteristics of convenience in carrying keys and easiness in changing a lock.

Description

technical field [0001] The invention relates to a mechanical lock, in particular to a purely mechanical password switch device and a lock cylinder device for various locks. Background technique [0002] Locks are widely used in daily life. Existing locks are roughly divided into two categories: mechanical locks and electronic locks, and mechanical locks are divided into ordinary mechanical locks and password mechanical locks. [0003] Ordinary mechanical locks are cheap to manufacture and are the most widely used, but their security is poor, the key is easy to be copied, the key is thick and heavy, and it is very inconvenient to wear it when going out. In addition, when a mechanical lock (such as a door lock) needs to be replaced, it usually needs to be replaced as a whole or the lock cylinder, which is cumbersome. [0004] The password mechanical lock does not need to wear a key, but the password must be remembered. Nowadays, people have too many passwords to remember, wh...
