External-lock-and-asynchronously-electromechanical-combined invisible alarm and anti-theft lock

Abstract

The invention discloses an external-lock-and-asynchronously-electromechanical-combined invisible alarm and anti-theft lock. A pressing spring in an external lock hole abuts against an inserting column in a pressing mode, the inserting column abuts against an inclined face groove in a sliding block in a pressing mode, an external spring is arranged behind the sliding block, and a push rod is arranged in front of the sliding block. An invisible key is hidden in or connected in an invisible hole in a hidden mode. A fixed contact is arranged on a lock body, a rotating contact is arranged on the rotating face or the rear face of a rear lock core, a master contact is arranged at the front end of the rear lock core, and a slave contact is arranged at the rear end of the front lock core. According to the lock, the front lock core is separated from the rear lock core completely, and the fixed contact and the rotating contact are connected with an electronic telecontrol device in a power supply circuit of an electromagnet. The power supply circuit of the electromagnet is switched off in the electronic telecontrol device, the master contact and the slave contact are connected to a power supply circuit of an asynchronous alarm system, the front lock core and the rear lock core cannot be rotated without a special key when unlocking is conducted, the purpose that the electromechanical interlocking function, the invisible function, the self-locking function and the asynchronous alarm function are integrated is achieved, and the safety index is high.

Description

Technical field [0001] The invention relates to an external lock asynchronous electromechanical hybrid alarm invisible anti-theft lock in the field of anti-theft locks. Background technique [0002] There are many types of anti-theft locks in use today, but they basically use the rotation of the key to drive the bolt to open the anti-theft lock. There is no interlocking device, an anti-theft lock that combines an electromechanical interlock and an alarm device, which can cause thieves or unlockers. The anti-theft lock is easily opened. The anti-theft locks that thieves and the king of unlocking cannot open are basically not used at present. Summary of the invention [0003] The purpose of the present invention is to provide a high-security anti-theft lock that cannot be opened by thieves and unlockers, which integrates asynchronous alarm, self-locking and electromechanical interlocking into one, and its method. [0004] In order to achieve the above objective, the lock hole of the...
