Invisible external-locking mechanical-electronic hybrid alarming anti-theft lock

Abstract

The invention discloses an invisible external-locking mechanical-electronic hybrid alarming anti-theft lock. A push rod of the lock is arranged in front of a sliding block in an ejecting mode and an inserting column is pressed on an inclined groove in an ejecting mode. An ejector rod in an unlocking guide hole is arranged on an interlocking plate in an annular groove in an ejecting mode, an interlocking pin on the interlocking plate is inserted into an interlocking hole in one locking column, and an interlocking spring pressed behind the interlocking plate in an ejecting mode is installed in an interlocking bearing hole. An invisible key is invisibly connected into and hidden in an invisible hole, a fixed contact and a rotary contact are connected with an electronic remote control device in a power supply circuit of an electromagnet, and a main contact and an auxiliary contact are connected in an asynchronous alarming system. The interlocking pin locks the corresponding lock column, the inserting column locks a front lock cylinder, the front lock cylinder and a rear lock cylinder are completely disconnected, the front lock cylinder and the rear lock cylinder cannot be rotated or connected if an interlocking key and a specially key are not used for unlocking, therefore, asynchronous alarming, mechanical interlocking and self-locking, mechanical-electronic interlocking are combined into a whole, the lock can only be unlocked when the two keys are used in cooperation, and the safety index is high.

Description

technical field [0001] The invention relates to an invisible anti-theft lock with an external lock electromechanical hybrid alarm in the field of anti-theft locks. Background technique [0002] There are many kinds of anti-theft locks in use today, but basically the key is rotated to drive the lock tongue to open the anti-theft lock. There is no anti-theft lock combined with an electromechanical interlock device and an alarm device, which makes it easy for thieves or unlocking kings to open the anti-theft lock. The anti-theft lock was opened. The anti-theft locks that thieves and unlocking kings cannot open are basically not used at present. Contents of the invention [0003] The purpose of the present invention is to provide a high-security anti-theft lock that combines asynchronous alarm, interlock that can only be opened with the cooperation of two keys, self-lock and electromechanical interlock that cannot be opened by thieves and unlock kings. Manufacture and its me...
