[0002] Electromagnetic mechanical interlocking is a safety protection device commonly used in power systems and automation control. It uses electromagnetic effects and mechanical linkage to ensure that equipment operates in the correct sequence under specific conditions, preventing unsafe situations caused by misoperation or failure. Electromagnetic mechanical interlocking is commonly used in circuit breakers, switchgear, elevator controls, crane systems, and other electromechanical equipment that require safety control.

[0003] During the use of the existing electromagnetic mechanical interlock, because the control element is usually placed next to the lock, if a strong magnet is used, the electromagnetic mechanical interlock may be adsorbed and opened, which is relatively unsafe when no one is around.

[0004] Therefore, in view of the fact that the existing electromagnetic mechanical interlock may be opened by a strong magnet because the control element is placed next to the lock, a highly protective electromagnetic mechanical interlock device can be designed to achieve a double-layer protection function.

The outer shell No. 1 bending column, the outer shell No. 2 bending column, the outer shell No. 3 bending column, and the outer shell No. 4 bending column are locked in the outer shell No. 1 and the outer shell No. 2. When the outer layer No. 1 shell hasp and the outer layer No. 1 shell lock buckle are aligned, the outer layer No. 1 shell hasp is pressed into the outer layer No. 1 shell lock buckle through the outer layer No. 1 shell shaft, and then the outer layer No. 1 shell lock buckle is locked. At this time, the closing is completed. When it needs to be opened, the reverse operation is performed. When the four keyed bullets slide to the uppermost and lowermost positions in the inner layer No. 1 shell and the inner layer No. 2 shell, the four keyed bullets are popped out and fixed by elastic springs, so as to achieve the function of second-level protection and the option of not using.

[0017] 3. When using the first level of protection, first insert the battery slot into the powered object, and then when the button is activated, power is supplied to the button through the battery slot, the button supplies power to the relay, and the relay supplies power to the coil. The coil is energized to generate magnetic force that attracts the magnetic block, and the lock head and the keyed housing are pushed toward the magnetic block to complete the opening operation. When closing, press the button, the coil loses power, and the rebound spring pushes the lock head, keyed housing and lock sleeve to close, achieving the effect of electromagnetic control of the switch.
