a security lock

Abstract

The invention provides a safety lock. The safety lock comprises a lock tongue, a lock cylinder and a key. The lock cylinder comprises a lock cylinder body, a lock cylinder cap and a connecting assembly. A lock channel is formed in the lock cylinder body, and an electronic control assembly and a mechanical control assembly which are both used for controlling the connecting assembly to move are arranged in the lock cylinder body. The key comprises a key rod and a holding part fixedly connected to one end of the key rod. A power source and a control chip connected with the power source are arranged in the holding part. Key teeth and a first contact chip connected with the control chip are arranged on the key rod. The key is inserted into the lock channel during unlocking, the first contact chip is in communication connection with the electronic control assembly, and the key teeth abut against the mechanical control assembly. By arranging the control chip and the contact chip on the key and arranging the electronic control assembly on the lock cylinder, key teeth of an electronic key and the key teeth of the key need to be in correspondence for unlocking the lock when the lock is in use, technological unlocking and violent unlocking are effectively prevented, and the safety is relatively high.

Description

technical field [0001] The invention relates to a lock, in particular to a safety lock. Background technique [0002] Lockset is a common anti-theft tool. Traditional locksets are usually mechanical anti-theft locks, which can be unlocked as long as the key is used to rotate the lock cylinder, which cannot meet people's anti-theft requirements in terms of anti-technical opening and violent opening. [0003] With the development of electronic technology, electronic anti-theft locks have emerged as the times require. Electronic anti-theft locks refer to locks that electronically identify, process relevant information, and control mechanical actuators to open and close, and have certain anti-destructive capabilities. Since the electronic key quantity of the electronic anti-theft lock can be a million times that of the mechanical lock, the electronically controlled locking point can be flexibly set, so that the locking point is not controlled by the rotation of the lock cylinder...

AI Technical Summary

Problems solved by technology

[0004] The electronic anti-theft locks currently on the market usually realize the locking or unlocking action through the electromechanical locking mechanism. Once the power is cut off, it will cause serious consequences that both inside and outside the lock cannot be unlocked.

For this reason, the electronic anti-theft lock needs to use a mechanical lock cylinder as a backup opening mechanism, which will leave a back door for technical opening and violent opening, and the security is relatively low
