[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0021] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a rear cover plate for the maintenance of a switch cabinet, including a cover plate main body 1. A detection hole 11 is provided on the cover plate main body 1. The detection hole 11 is used to facilitate the insertion of a temperature detector into the cabinet body to detect the temperature of the component connection points in the cabinet body. A glass slide rail 12 is fixed on the inner side surface of the cover plate main body 1. The glass slide rail 12 is located on the edge of the detection hole 11. A glass 2 slides in the glass slide rail 12. By providing the glass 2, it is convenient to observe the structure in the cabinet body. A push rod 15 slides at one end of the glass slide rail 12. By moving the push rod 15 in the glass slide rail 12, the glass 2 is pushed to move, so that the detection hole 11 is opened, facilitating the insertion of the temperature detector into the switch cabinet to detect the temperature of the component connection points in the cabinet body. A spring connection block 13 and a return spring 14 are fixed at the other end. When the push rod 15 drives the glass 2 to move, the return spring 14 will be compressed. At this time, the push rod 15 resets, and the glass 2 will reset under the elastic force of the return spring 14, realizing the automatic closing function of the detection hole 11. The push rod 15 and the return spring 14 are respectively located on both sides of the glass 2. The push rod 15 is used to push the glass 2 to move, and the return spring 14 is used to reset the glass 2. One end of the push rod 15 extends into the glass slide rail 12, and the other end extends out of the glass slide rail 12 and is connected to the operating mechanism. To sum up, by controlling the left and right movement of the push rod 15 through the operating mechanism, the glass 2 is pushed to move in the glass slide rail 12, and the detection hole 11 is opened, facilitating the temperature detector to extend into the switch cabinet for temperature detection of the component connection points. The existing rear covers of switch cabinets are all connected to the cabinet body through fasteners, making detection difficult. Therefore, this technical solution improves the inspection efficiency. At the same time, the movement of the push rod 15 will cause the glass 2 to move and compress the return spring 14. After the push rod 15 resets, the elastic force generated by the return spring 14 will be applied to the glass 2, causing the glass 2 to reset, realizing the automatic closing of the detection hole 11.

[0022] As Figure 3 shown, the operating mechanism includes a moving shaft 17. A sliding hole 3 is provided on the cover plate main body 1. The moving shaft 17 moves in the sliding hole 3. Symmetrically arranged connecting rods 16 are connected to the moving shaft 17. The connecting rods 16 are rotatably connected to the inner side of the cover plate main body 1 through a rotating shaft 18. The other end of the connecting rod 16 is connected to the push rod 15. By moving the moving shaft 17 in the sliding hole 3, the moving shaft 17 can drive the connecting rod 16 to rotate around the rotating shaft 18. In this way, the rotation of the connecting rod 16 will drive the push rod 15 to move left and right in the glass slide rail 12.

[0023] The connecting rod 16 is provided with a first elongated hole 161 and a second elongated hole 162. The first elongated hole 161 and the second elongated hole 162 are respectively located on both sides of the rotating shaft 18. One end of the push rod 15 is fixed with a connecting shaft 151. The connecting shaft 151 is arranged in the first elongated hole 161, and the moving shaft 17 is inserted into the second elongated hole 162. By providing the first elongated hole 161 and the second elongated hole 162, when the connecting rod 16 rotates, it can automatically adjust the distance of the push rod 15 in the first elongated hole 161, and at the same time, it can also adjust the position of the moving shaft 17 in the second elongated hole 162, making the movement of the push rod 15 smoother.

[0024] As Figure 2 shown, one end of the moving shaft 17 is fixed with a handle 171. The handle 171 is provided with a limiting groove 172. The front surface of the cover plate main body 1 is fixed with a limiting shaft 19. The limiting shaft 19 is located on one side of the sliding hole 3. The limiting shaft 19 cooperates with the limiting groove 172 to fix the position of the moving shaft 17. At this time, one end of the moving shaft 17 located in the sliding hole 3 makes the swinging amplitude of the connecting rod 16 fixed, further locking the pushing distance of the push rod 15 and maintaining the open state of the detection hole 11, which is convenient for detection.

[0025] There are two push rods 15, and the two push rods 15 are symmetrically distributed up and down in the glass slide rails 12 at the upper and lower ends. By simultaneously pushing the upper and lower ends of the glass 2 through the push rods 15 distributed up and down, the movement of the glass 2 is made smoother.

[0026] As Figure 1 shown, the end of the push rod 15 is fixed with a push block 152. The end face of the push block 152 is attached to the inner wall of the glass slide rail 12 to prevent the push rod 15 from moving around in the glass slide rail 12.

[0027] The cover plate main body 1 is also provided with a plurality of heat dissipation holes 4, and the heat dissipation capacity of the cover plate main body 1 is improved through the heat dissipation holes 4.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
