[0029] In the above structure, the control mainboard, setting keys and electromagnet are integrated into an electromagnet integrated unit, and the control mainboard is used instead of wires to directly control the electromagnet, which eliminates the wiring startup of the electromagnet and improves the safety of the electromagnet. At the same time, the integrated design can reduce the use of parts and save costs. At the same time, integrating the panel with the power supply device also has the effect of saving costs.

[0030] Specifically, the lock housing body 10 has fixing parts 100 protruding outward on both sides, and the fixing parts 100 are provided with screw holes 101 for screw fixing. The use of two fixing parts can not only achieve a symmetrical and beautiful effect, but also achieve a two-point fixing method to increase stability.

[0031] Specifically, a top cover 120 is provided at the upper end of the limiting frame 12, and convex portions 121 are provided on both sides of the top cover 120. A first groove 102 corresponding to the position of the convex portion 121 is provided on the lock shell body 10. The cooperation of the convex portion and the groove can ensure that the position of the top cover will not be wrong, while reducing the use of connecting parts and further saving costs.

[0032] Specifically, a limiting cover 122 is provided on the top cover 120, and both ends of the limiting cover 122 extend downward to form an extension portion 123, and the extension portion 123 is provided with a second groove 124 used in conjunction with the convex portion 121, and a first through hole 125 is provided on the limiting frame 12, and a second through hole 126 corresponding to the position of the first through hole 125 is provided on the top cover 120, and a third through hole 127 corresponding to the position of the second through hole 126 is provided on the limiting cover 122, and the second groove and the convex portion cooperate to limit the position of the limiting cover.

[0033] Specifically, the locking structure 11 includes a fixed iron core 110, a movable iron core 111, a spring 112 and a reset spring 113. The fixed iron core 110 is arranged in the first through hole 125, and the lower end of the fixed iron core 110 is fixedly arranged on the lock housing body 10. The movable iron core 111 is provided with a flange 114. One end of the movable iron core 111 passes through the second through hole 126 to the first through hole 125, and the other end of the movable iron core 111 passes through the third through hole 127. The spring 112 is arranged on the flange 114. 4 and the limit cover 122, the return spring 113 is sleeved on the movable iron core 111, and the two ends thereof respectively abut against the flange 114 and the top cover 120. By using the locking structure, the movable iron core can be magnetized and moved down to unlock after the electromagnet is energized, and the return spring is pressed by the flange while the movable iron core moves down to deform. When the electromagnet is no longer energized, the movable iron core is no longer magnetized and loses its magnetic force. The return spring drives the movable iron core to bounce up and reset, and the flange abuts against the limit cover to ensure that the movable iron core will not be bounced away by the restoring force generated by the return spring.
