Password switch device and lock cylinder device for lockset

Abstract

The invention relates to a mechanical lock, and proposes a combination switch device for a lock, which includes a combination block and a drilled card. The drilled card is a rectangular sheet with a plurality of card holes. The combination block includes a rectangular base, a sliding Block and lock pin, there is a slider grid in the base, the slider is placed in the slider grid, the bottom of the slider has a card slot, and the front end has a movable lock pin, and the rear of the base corresponds to the position of the card slot. There are card sockets, There is a lock pin opening corresponding to the position of the lock pin. There are several marble pairs distributed in the base and the slider. Insert the drilled card into the card slot. If all the card holes match the pin pin pairs, the slider can drive the lock pin into the rectangular base. Inside; the lock cylinder device adopting this password switch device includes a lock cylinder and a code block, the front end of the lock core is provided with a driving rod groove, and a rectangular code block groove and a spring groove are opened in the lock cylinder, and the spring is placed in the spring groove Inside, the cipher block is placed in the cipher block slot, and the lock cylinder is horizontally provided with a lock pin bayonet and a lock pin slot corresponding to the lock pin of the cipher block. The invention has the substantive characteristics that the key is convenient to carry and the lock is easy to change.

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 is usually necessary to replace the whole or replace 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 re...

AI Technical Summary

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
