It can be understood that when the second lock block is pushed by the electromagnetic push rod, the second lock block drives the second protrusion to move when it rotates, and the second protrusion can produce a pushing action on the first protrusion on the first lock block, so that the first lock block rotates when pushed. At this time, the opening direction of the card interface of the first lock block can be changed from the locking area to the unlocking area, and the lock rod can be disengaged from the card interface to achieve unlocking; conversely, when the electromagnetic push rod is reset, the electromagnetic push rod no longer pushes the second lock block, the second lock block is reset, and the second protrusion no longer pushes the first protrusion.

[0040] Reference Figures 1 to 3, an embodiment of the utility model provides an electromagnetic lock with a compact structure, including a mounting plate 100, which is provided with an unlocking area and a locking area;

[0041] The first locking block 200 is rotatably mounted on the mounting plate 100. The first locking block 200 has a card interface 210. The opening direction of the card interface 210 can be switched between the unlocking area and the locking area. A first protrusion 220 is provided on one side of the first locking block 200. The first protrusion 220 is close to the locking area. The second locking block 300 is rotatably mounted on the mounting plate 100. The second locking block 300 is provided on the same side as the locking area. The second locking block 300 is close to the first protrusion 220. A second protrusion 310 is provided on one side, and the first protrusion 220 is movably connected to the second protrusion 310; an electromagnetic device 400 is fixed to the mounting plate 100, and the electromagnetic device 400 is provided at one end away from the second protrusion 310. The electromagnetic device 400 is provided with a movable electromagnetic ejection rod 410, and the end of the electromagnetic ejection rod 410 is connected to the second locking block 300; a locking rod 500 is provided on the outside of the mounting plate 100, and the locking rod 500 is movably plugged into the card interface 210;

[0042] The electromagnetic push-up can push the second locking block 300 to rotate, and when the second locking block 300 rotates, it can drive the first locking block 200 to rotate to achieve the switching of the opening direction of the card interface 210.

[0043] The working principle of the electromagnetic lock of the present application is as follows: the electromagnetic push rod 410 can push the second lock block 300 to rotate, and when the second lock block 300 rotates, it can drive the first lock block 200 to rotate, thereby switching the opening direction of the card interface 210, thereby completing the unlocking and locking actions. When the second locking block 300 is in the state of being unlocked, the second protrusion 310 no longer pushes the first protrusion 220, and the first locking block 200 can be reset. The direction of the card interface 210 can be turned from the unlocking area to the locking area. At this time, if the locking bar 500 is in the card interface 210, the locking is completed.

[0044] According to some embodiments of the present application, the first locking block 200 is a cam disc structure, and the first protrusion 220 and the first locking block 200 are manufactured as a homogeneous whole, thereby ensuring the stability and reliability of the structure.

[0045] According to some embodiments of the present application, a first limiting shaft 110 and a second limiting shaft 120 are provided on the mounting plate 100 . Specifically, the first locking block 200 is rotatably connected to the first limiting shaft 110 , and the second locking block 300 is rotatably connected to the second limiting shaft 120 .

[0046] According to some embodiments of the present application, to enhance the reliability of locking and unlocking, the present application further includes a first spring 130 and a second spring 140. Specifically, one end of the first spring 130 is fixedly connected to the mounting plate 100, and the other end is connected to the first locking block 200. The second spring 140, on the other hand, is fixedly connected to the mounting plate 100, and the other end is connected to the second locking block 300. When the opening of the card interface 210 faces the locking zone, the first spring 130 is in a stretched state, providing the locking force during locking. When the opening of the card interface 210 faces the unlocking zone, the second spring 140 is in a stretched state, providing the reset force during unlocking. It is understood that the primary function of the first spring 130 is to utilize its elastic reset function to cooperate with the second locking block 300 to rotate the first locking block 200 when the electromagnetic lock needs to be unlocked, ensuring that the opening of the card interface 210 accurately switches from the locking zone to the unlocking zone, ensuring smooth unlocking. The second spring 140, on the other hand, is used to reset the second locking block 300.

[0047] According to some embodiments of the present application, to constrain the swing travel of the second locking block 300, a first limiting post 150 and a second limiting post 160 are provided on the mounting plate 100, located on the same side as the electromagnetic device 400. The gap between the first limiting post 150 and the second limiting post 160 forms a limiting active area, and the end of the second locking block 300 proximal to the electromagnetic device 400 extends into the limiting active area, ensuring that the opening orientation of the card interface 210 can accurately switch from the locking area to the unlocking area, ensuring smooth unlocking.

Furthermore, an ejection plate 411 is mounted on the end of the electromagnetic ejection rod 410, and the ejection plate 411 abuts against the abutment block 320 to improve the stability and reliability of the transmission.

[0049] According to some embodiments of the present application, as shown in the figure, the electromagnetic lock of the present application further includes a lock box 700. Specifically, the lock box 700 is composed of a mounting plate 100, a front sealing plate, a left sealing plate, and a right sealing plate. The mounting plate 100 is an L-shaped structure. A movable opening 170 is provided on the mounting plate 100 for the locking rod 500 to enter and exit. The movable opening 170 is located within the unlocking area of ​​the mounting plate 100. The locking rod 500 can be inserted into the card interface 210 of the first lock block 200 in the lock box 700 through the movable opening 170.

[0050] This application also provides a window utilizing the aforementioned electromagnetic lock. Specifically, the window sash is hinged to the window frame, a mounting plate 100 is fixed to the window frame, the window sash is provided with a fixing bracket 600, and a locking rod 500 is fixed to the fixing bracket 600.
