A kind of anti-theft mechanical lock

Abstract

The invention provides an anti-theft mechanical lock. The anti-theft mechanical lock comprises a lock tongue, a lock core and a key. The lock core comprises a core body, a core cap and a connection assembly. The core body is provided with a lock channel, a mechanical control assembly and a lock groove. The core cap is provided with a clamping groove. The key is provided with a key rod. The key rod is provided with a tooth pattern. During unlocking, the key is inserted into the lock channel in a penetrating manner, and the tooth pattern ejects and makes contact with the mechanical control assembly so that the mechanical control assembly can relieve limitation to the connection assembly. The connection assembly comprises a chip, a top piece and a first spring. After unlocking is completed, the top piece penetrates the lock groove and the clamping groove, and when locking is carried out, the end face of the end, facing the core cap, of the chip is flush with the end face of the core body. By arranging the connection assembly, the top piece on the connection assembly is used for transmitting connection or disconnecting the core body from the core cap, the anti-theft mechanical lock is hard to violently unlock, and safety is relatively high.

Description

technical field [0001] The invention relates to a lock, in particular to an anti-theft mechanical lock. Background technique [0002] Mechanical lock is a common anti-theft tool. The traditional mechanical lock mainly includes a hollow lock cylinder sleeve, a lock cylinder rotor installed in the lock cylinder sleeve, and accommodating parts respectively installed in the lock cylinder sleeve and the lock cylinder rotor. The pins of the lock cylinder in the groove are pushed away from the blocking position by the matching key when unlocking, and then the key is turned to drive the rotor of the lock core to stir the dead bolt to realize unlocking. [0003] As the traditional mechanical lock is directly driven by the lock cylinder rotor, as long as the lock cylinder rotor is turned, the lock can be unlocked, and the lock cylinder rotor can easily use the master key to move the lock cylinder pins so that all the lock cylinder pins are pushed away in an instant.

Problems solved by technology

[0003] As the traditional mechanical lock is directly driven by the lock cylinder rotor, as long as the lock cylinder rotor is turned, the lock can be unlocked, and the lock cylinder rotor can easily use the master key to move the lock cylinder pins so that all the lock cylinder pins are pushed away in an instant. Unlocking is achieved by blocking the position, or using a special tool such as a screwdriver to twist off the pin of the lock cylinder, and forcibly turning the rotor of the lock cylinder to unlock the lock, which is relatively low in safety
