Electromagnetic control lock for cabinet

Abstract

The invention relates to the technical field of cabinet safety, in particular to an electromagnetic control lock for a cabinet. The electromagnetic control lock for the cabinet is used for fixedly locking a left overturning cabinet door and the inner side surface of a front operation port through an upper electromagnetic elastic locking mechanism and a lower electromagnetic elastic locking mechanism, and an internal lock body composed of a main lock body, an internally-arranged solenoid valve, a lock cylinder shaft, a clutch sliding block and a normally closed magnetic control switch is fixedto the inner side surface of a right overturning cabinet door through bolts. Magnetic steel inside the internal lock body controls the normally closed magnetic control switch to open and close, so that the internally-arranged solenoid valve is opened and closed to control the connection state of the clutch sliding block and a lock cylinder cam, a mechanical key is prevented from unlocking under apower-on state, and the security of theft prevention is improved.

Description

technical field [0001] The invention relates to the technical field of cabinet safety, in particular to an electromagnetic control lock for a cabinet. Background technique [0002] Generally, the mortise type electric control anti-theft lock adopts a spare mechanical lock core and an electric control mechanism to realize the opening or locking of the lock tongue, and these two opening or locking methods are independently completed, that is, the spare mechanical key can be used. The lock can be opened and closed independently without the interference of the electric control mechanism, and the same is true for the electric control mechanism; the traditional electric control lock structure in which the mechanical opening and closing tools and the electric control opening and closing tools coexist is not suitable for public places such as The anti-theft door of the computer room and base station of the iron tower company; the reason is that the normal and legal means of opening ...

Problems solved by technology

[0002] Generally, the mortise type electric control anti-theft lock adopts a spare mechanical lock core and an electric control mechanism to realize the opening or locking of the lock tongue, and these two opening or locking methods are independently completed, that is, the spare mechanical key can be used. The lock can be opened and closed independently without the interference of the electric control mechanism, and the same is true for the electric control mechanism; the traditional electric control lock structure in which the mechanical opening and closing tools and the electric control opening and closing tools coexist is not suitable for public places such as The anti-theft door of the computer room and base station of the iron tower company; the reason is that the normal and legal means of opening and closing the anti-theft lock in the communication computer room of the iron tower must be an electronically controlled remote control lock, because the electronically controlled remote opening and closing can simultaneously realize scientific control such as remote monitoring , while the mechanical key switch lock cannot achieve the above purpose, it can only be used as a backup means when the power fails

This creates a contradiction in management, that is, the mechanical spare lock cylinder and the matching mechanical key are uncontrollable (easy to be copied, easy to be hidden, and easy to become a weak link for thieves)
