[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Combination Figures 1-4An easy-to-maintain electrical control cabinet includes a cabinet body 1 and a mounting plate 2. A positioning mechanism 3 is provided between the cabinet body 1 and the mounting plate 2. The positioning mechanism 3 includes four guide rails 301 and two positioning racks 302. The four guide rails 301 are fixedly installed side by side on both sides of the inner wall of the cabinet body 1. The two positioning racks 302 are fixedly installed side by side on both sides of the inner wall of the cabinet body 1. Two slide blocks 303 are fixedly installed side by side on both sides of the mounting plate 2. Two positioning seats 304 are slidably installed through the mounting plate 2. Limiting seats 305 are fixedly installed on the outside of the positioning seats 304 and fixedly installed on the mounting plate 2. A buffer spring 306 is fixedly installed between the limiting seat 305 and the positioning seat 304.

[0024] Four sliding blocks 303 are respectively snapped onto four guide rails 301. The upper and lower guide rails 301 face opposite directions, allowing the mounting plate 2 to move within the cabinet 1 under the action of the guide rails 301 and the sliding blocks 303. Thanks to the orientation of the upper and lower guide rails 301, the mounting plate 2 cannot detach from the cabinet 1. Two positioning seats 304 face opposite directions. Two support plates are mounted side by side on the mounting plate 2, with the positioning seats 304 located above the support plates. The front end of the positioning seats 304 is fixedly fitted with teeth, and the positioning rack 302 is adapted to the teeth. When the two positioning seats 304 are simultaneously controlled to move towards the center of the mounting plate 2, the positioning seats 304 will disengage the buffer spring 306 from the positioning rack 302, thereby removing the restriction of the positioning rack 302 on the mounting plate 2. At this time, controlling the mounting plate 2 to move within the cabinet 1 can change the position of the mounting plate 2 within the cabinet 1, making the cabinet 1 easier to clean, and at the same time, control the mounting plate 2 to move to a position that is convenient for maintenance. Example 2

[0025] See Figure 5 and Figure 6 The rear of the cabinet 1 is provided with a loading and unloading mechanism 4. The loading and unloading mechanism 4 includes a baffle 401 and four threaded shafts 402. The four threaded shafts 402 are respectively fixedly installed at the four corners of the rear of the cabinet 1. Each of the four corners of the baffle 401 is fixedly installed with a buckle 403. A fastening nut 404 is threaded on the threaded shaft 402. A limit rod 405 is fixedly installed at one end of the fastening nut 404. A baffle 406 is sleeved on the outside of the limit rod 405 and fixedly installed on the cabinet 1.

[0026] A cylinder is fixedly installed at one end of the threaded shaft 402, and the buckle 403 is adapted to the cylinder. By controlling the baffle 401, the buckle 403 is fastened to the threaded shaft 402. Further rotation of the fastening nut 404 clamps the buckle 403, and the connection between the baffle 401 and the cabinet 1 is achieved under the action of the fastening nut 404 and the buckle 403. In use, the rear of the cabinet 1 can be quickly opened by rotating the fastening nut 404 and removing the baffle 401. The length of the baffle 406 is less than the sum of the lengths of the threaded shaft 402 and the fastening nut 404. The buckle 403 is U-shaped and the opening of the buckle 403 faces downward, so that the limiting rod 405 is always located between the baffles 406, thereby preventing the fastening nut 404 from being lost.

[0027] In actual operation, when both positioning seats 304 are controlled to move towards the middle of the mounting plate 2 at the same time, the positioning seats 304 will disengage the buffer spring 306 from the positioning rack 302, and then contact the restriction of the positioning rack 302 on the mounting plate 2. At this time, the mounting plate 2 is controlled to move inside the cabinet 1, which can change the position of the mounting plate 2 inside the cabinet 1, making the cabinet 1 easier to clean, and at the same time control the mounting plate 2 to move to a position that is easy to maintain.

[0028] By controlling the baffle 401 to fasten the buckle 403 onto the threaded shaft 402, and further rotating the fastening nut 404 to clamp the buckle 403, the baffle 401 is connected to the cabinet 1 under the action of the fastening nut 404 and the buckle 403. In use, the rear of the cabinet 1 can be quickly opened by rotating the fastening nut 404 and removing the baffle 401, which greatly improves the maintenance efficiency of the control cabinet.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
