[0036] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0037] Reference Figures 1 to 5 An embodiment of the electromagnet of the present invention is presented:

[0038] An electromagnet 1 includes an electromagnet base 11, a brake plate 12, an electrical connection plate 16, a spring adjustment member 17, and an electromagnet body 13.

[0039] Two electromagnet locking holes 111 are arranged opposite each other on the electromagnet base 11. Spring-loaded connecting blocks 121 are provided on both sides of the brake pad 12.

An electromagnet baffle 116 is provided on the side of the electromagnet body 13 near the housing through-hole 221 on the lock housing 2. The electromagnet baffle 116 blocks the brake pad 12, preventing unauthorized unlocking using a wire tool.

[0047] An adjustment groove 117 is provided on the electromagnet base 11. Two adjustment groove connection holes 118 are arranged opposite each other on the inner side of the adjustment groove 117. The two ends of the spring adjustment member 17 are rotatably connected within the adjustment groove connection holes 118. The spring adjustment member 17 is located on one side of the brake pad 12, and its lifting height can be adjusted. When the lifting height is at its lowest, it is in a normally open state. Multiple adjustment member positioning protrusions are provided on the side of the spring adjustment member 17. Multiple connection hole positioning slots that fit the adjustment member positioning protrusions are provided within the adjustment groove connection holes 118. Through the cooperation of the adjustment member positioning protrusions and the connection hole positioning slots, the state of the spring adjustment member 17 can be positioned.

[0048] The electromagnet body 13 is fixed to the other side of the electromagnet base 11. The electromagnet body 13 contains a pusher return spring 14 and a pusher 115. The pusher 15 has a pusher connecting groove at its bottom, and the pusher return spring 14 is located within the pusher connecting groove. The pusher return spring 14 drives the pusher 115 to move, thereby resetting the brake pad 12. The brake pad 12 then limits the movement of the pusher 15. When the electromagnet body 13 is working, it can attract the brake pad 12, causing the brake pad 12 to move towards the electromagnet body 13.

[0049] The electromagnet 1 has a first base connecting groove 112 and a second base connecting groove 113 on opposite sides of its base. The first base connecting groove 112 contains two first electrical connecting grooves 114, and the second base connecting groove 113 contains two second electrical connecting grooves 115. An electrical connecting piece 16 can be positioned within either the first base connecting groove 112 or the second base connecting groove 113, depending on whether the door opens to the left or right. One end of the electrical connecting piece 16 is connected to the electromagnet body 113, and the other end is connected to an external circuit entering through the housing through-hole 221.

[0050] The rear end of the rotatable limiting rod 9 can cooperate with the brake pad 12, thereby locking the rotatable limiting rod 9 through the brake pad 12. When locking, the lock seat on the other side will press the first lock tongue 3 into the lock housing 2, thereby compressing the first return spring 31 through the first lock tongue 3. Subsequently, after the electromagnet 1 drives the brake pad 12 to move, the rotatable limiting rod 9 will release the limitation on the lock tongue connecting seat 8, thereby driving the second lock tongue 4 to move backward through the first return spring 31 to achieve unlocking.

[0051] The lower housing 21 of the lock is equipped with an unlock button 7 and an inner lock cylinder 5. The unlock button 7 has an unlock button pressing head 71 at its bottom, which drives the brake plate 12 to move, thus unlocking the lock. The inner lock cylinder 5 has an inner lock cylinder positioning connector 51 on its inner side, and an unlock button 7 has an unlock button positioning groove 72. Rotating the inner lock cylinder 5 allows the inner lock cylinder positioning connector 51 and the unlock button positioning groove 72 to engage, thus locking the unlock button 7 and preventing unlocking via the unlock button 7. The upper housing 22 of the lock is equipped with an outer lock cylinder 6, whose inner side is connected to the inner lock cylinder 5 via a strip-shaped connecting piece. The outer lock cylinder 6 drives the inner lock cylinder 5 to rotate, thereby unlocking or locking the unlock button 7 via the inner lock cylinder 5.
