A ball 15 is fixedly connected to the side wall of the rotating door 3. The ball 15 can be made of wear-resistant and elastic rubber to facilitate engagement with a semi-circular plate 20 and reduce wear. A handle 4 is fixedly connected to the side wall of the rotating door 3. The handle 4 can be made of plastic with a non-slip surface for easy operation. A filter screen 16 is fixedly connected inside the rotating door 3. An engagement assembly is provided on the inner wall of the housing 1. The engagement assembly is used to control the opening and closing function of the rotating door 3. The engagement assembly includes a first fixing plate 17. The first fixing plate 17 can be made of aluminum alloy, which is lightweight and high-strength. The bottom of the first fixing plate 17 is fixedly connected to the inner wall of the housing 1. A rotating part is rotatably connected inside the first fixing plate 17. The fixed column 21 can be made of carbon steel to ensure strength and wear resistance. The outer wall of the fixed column 21 is rotatably connected to a semi-circular plate 20. The outer wall of the semi-circular plate 20 is fixedly connected to a second support plate 19.

[0035] Specifically, when using the combined magnetic micro circuit breaker, first need to operate the rotating door 3. When we manually pull the rotating door 3, the rotating door 3 will be subjected to an outward pulling force. Since the rotating door 3 is connected with the shell 1 through the hinge 2, the hinge 2 plays a connecting and rotating role, so that the rotating door 3 can be rotated and opened with the hinge 2 as the axis. In the process of force movement of the rotating door 3, the clamping ball 15 fixedly connected with the side wall will also be subjected to the force. After the clamping ball 15 is subjected to the force transmitted by the rotating door 3, it will tightly clamp the inner wall of the semicircular plate 20. At this time, the semicircular plate 20 will be subjected to force due to the extrusion force of the clamping ball 15. After the semicircular plate 20 is subjected to force, it will drive the second support plate 19 fixedly connected with the outer wall. After the second support plate 19 is subjected to the pulling force of the semicircular plate 20, it will further drive the spring 18 connected with the side wall to contract. One end of the spring 18 is fixedly connected with the side wall of the second support plate 19, and the other end is connected with the side wall of the first fixed plate 17. Through the clamping of the clamping ball 15 and the semicircular plate 20 and the elastic effect of the spring 18, a clasp type opening and closing effect is achieved. This design not only ensures that the rotating door 3 can tightly fit the shell 1 when closed, and plays a good protection role, but also makes it easy to open the rotating door 3 by simple pulling operation when it needs to be opened, convenient and fast, and also has certain stability and reliability, ensuring the convenience and safety of the combined magnetic micro circuit breaker in use.

[0037] Specifically, after the motor 7 starts, the output end of the motor 7 starts to drive the threaded rod 8 to rotate at a constant speed. During the rotation of the threaded rod 8, the rotation is converted into the linear movement of the rotating plate 9 on the outer wall through the interaction of the threads. With the movement of the rotating plate 9, the first connecting plate 11 tightly connected to the outer wall of the rotating plate 9 is also driven to move synchronously. After the first connecting plate 11 is stressed, the second connecting plate 12 fixedly connected to the side wall of the first connecting plate 11 is driven to move, so that the second connecting plate 12 also moves. When the second connecting plate 12 moves, the third connecting plate 13 connected to the second connecting plate 12 is further driven to slide along the inner wall of the hollow plate 6. Subsequently, the third connecting plate 13 drives the fourth connecting plate 14 on the side wall to rotate under the action of force. Since the fourth connecting plate 14 is rotatably connected to the side wall of the louver 5, the rotation of the fourth connecting plate 14 will eventually drive the louver 5 on the side wall to rotate. Through this series of mechanical transmission, the effect of controlling the gap size of the louver 5 is accurately achieved. This design can flexibly adjust the opening and closing degree of the louver 5 according to actual needs, so as to effectively control the air flow, light transmission amount and the like, is widely used in ventilation, heat dissipation, light shielding and other scenes, and improves the functionality and adaptability of the equipment.

[0038] Referring toFigure 5 The inner wall of the shell 1 is provided with a fixing assembly for connecting the function of the circuit breaker 24, which includes a second fixing plate 22. The second fixing plate 22 can be made of high-strength metal material, such as stainless steel plate, which has good rigidity and corrosion resistance, and can be stably connected to the inner wall of the shell 1. The side wall of the second fixing plate 22 is fixedly connected to the inner wall of the shell 1. The second fixing plate 22 is internally threadedly connected with a nut 23. The nut 23 can be made of carbon steel material, which has high strength and good thread engagement performance after proper heat treatment, can ensure the close connection with the second fixing plate 22 and is convenient for installation and disassembly.

The outer wall of the circuit breaker 24 is arranged inside the shell 1. The shell 1 is provided with a plurality of circuit breakers 24.

[0039] Specifically, in the structural design of the combined magnetic micro circuit breaker, the second fixing plate 22 inside the shell 1 plays an important role in driving the circuit breaker 24. The second fixing plate 22 is tightly attached to the inner wall of the shell 1, and by using its own structure and connection method, it gives the circuit breaker 24 a stable support force, so that it can be tightly fixed in the corresponding position inside the shell 1. Then, in order to further enhance the fixing effect and ensure that the circuit breaker 24 remains stable under various working conditions, the second fixing plate 22 is fixed more firmly by the nut 23. The nut 23 is gradually tightened under the thread cooperation with the second fixing plate 22, generating a strong fastening force to firmly fix the second fixing plate 22 inside the shell 1. In this way, through the synergistic effect of the second fixing plate 22 and the nut 23, the effect of fixing the circuit breaker 24 is achieved, effectively preventing the circuit breaker 24 from being displaced or loosened due to external vibration, current impact and other factors, and ensuring the stability of the combined magnetic micro circuit breaker.
