[0003] In the prior art, when a circuit in the distribution box fails or during daily maintenance, a maintenance board needs to be hung on the box body during the maintenance process to warn other staff not to operate the distribution box. However, the existing maintenance boards are generally simply hung on the distribution box, and are prone to falling off or being accidentally touched by others and falling, causing other staff to operate the circuits or electrical switches in the distribution box (such as power-on operation) without knowing it. In severe cases, serious personal safety accidents are likely to occur, and in mild cases, equipment damage is caused. Even if no accident occurs, after others operate the circuits or switches in the distribution box, it will affect the maintenance personnel's judgment of circuit faults, making it difficult to maintain or repair.

[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 embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 5 , in the embodiment of the present invention, a wiring box that is easy to maintain includes a wiring box 1 with an open end. A rotating door 2 is rotatably installed on one side of the open end of the wiring box 1. A plugging slot 4 is vertically opened on a side plate of the wiring box 1. A maintenance board 5 is inserted into the inner wall of the plugging slot 4. A handle 6 is fixedly installed at the outer end of the maintenance board 5 in the plugged state and located outside the wiring box 1. Locking mechanisms are distributed on the inner cavity of the maintenance board 5 and the wiring box 1; the locking mechanisms are used to limit the position of the maintenance board 5 in the plugged state to prevent the maintenance board 5 from falling off or being taken away by others; the maintenance board 5 is used to block the circuits and switches inside the wiring box 1 when the maintenance personnel are not present, to prevent non-maintenance personnel from turning on the electrical switches inside the wiring box 1.

[0022] In this embodiment: When maintaining or repairing the circuits inside the wiring box 1, first turn off the electrical switches inside the wiring box 1, and then maintenance can be carried out. If during the maintenance or repair process, the maintenance personnel need to go to the toilet or need to fetch maintenance accessories and need to leave temporarily, at this time, insert the maintenance board 5 into the plugging slot 4 and continuously push the maintenance board 5 until one end of the maintenance board 5 contacts the inner wall of the wiring box 1. At this time, use a tool to partially dock with the locking mechanism on the maintenance board 5 and rotate this part of the locking mechanism through the tool until this part of the locking mechanism is docked with the locking mechanism in the inner cavity of the wiring box 1, and the maintenance board 5 can be limited in the current position, which can effectively prevent the maintenance board 5 from falling off or being taken off by non-maintenance personnel, and prevent others from operating the circuits inside the wiring box 1. Even if the operation process will not produce dangerous consequences, it can also avoid the phenomenon of difficult maintenance caused by others' operations (because after others operate the circuits, it will affect the maintenance personnel's judgment of circuit problems).

[0023] Please pay special attention to Figure 3 、 Figure 4 And Figure 5, the locking mechanism includes a fixed frame 7 fixedly installed on the inner wall of the distribution box 1. The fixed frame 7 is in a rectangular structure. An engaging box 8 is fixedly installed outside the fixed frame 7. The engaging box 8 is in a hollow structure, and one end of the engaging box 8 close to the fixed frame 7 is in an open structure. An opening 11 equal in size to the opening of the engaging box 8 is provided at the overlapping position of the fixed frame 7 and the engaging box 8. The locking mechanism further includes a connecting shaft 12 rotatably installed inside the maintenance plate 5, and a receiving groove 9 provided inside the maintenance plate 5. One end of the connecting shaft 12 penetrates into the inner cavity of the receiving groove 9, and a rotating plate 10 is fixedly connected to the outer wall of the connecting shaft 12 inside the inner cavity of the receiving groove 9. The end of the connecting shaft 12 away from the rotating plate 10 is flush with the outer wall of one end of the maintenance plate 5, and a tool groove 13 is provided at the end of the connecting shaft 12 flush with the inner wall of the maintenance plate 5.

[0024] In this embodiment: Use a tool that fits the tool groove 13. Since the tool groove 13 is a special-shaped structure and not a conventional structure, the tool is also specially made and not easily obtained by others. Then, dock the tool with the tool groove 13, and then rotate the tool. The tool transmits the torque to the connecting shaft 12, and the connecting shaft 12 rotates. The rotating connecting shaft 12 drives the rotating plate 10 to rotate. The rotating plate 10 rotates from the vertical state (i.e., the state overlapping with the receiving groove 9) towards the horizontal direction. The rotating plate 10 rotates out of the receiving groove 9 and rotates through the opening 11 into the inner cavity of the engaging box 8, and is hooked to the inner cavity of the engaging box 8. At this time, the maintenance plate 5 cannot be taken out by pulling the handle 6. At the same time, the maintenance plate 5 completely covers the circuit and the electric switch inside the distribution box 1, avoiding non-maintenance personnel from taking away the maintenance plate 5 and also avoiding non-maintenance personnel from operating the circuit and the electric switch inside the distribution box 1;

[0025] After the maintenance personnel come back, use the tool to dock with the tool groove 13 again and rotate the tool in the reverse direction. The tool drives the connecting shaft 12 to rotate in the reverse direction. At this time, the connecting shaft 12 drives the rotating plate 10 to rotate in the reverse direction until the rotating plate 10 is misaligned with the engaging box 8 and the opening 11. At this time, the maintenance plate 5 can be taken out from the insertion slot 4 through the handle 6;

[0026] It should be noted that: The warning words "Under maintenance, do not touch" are written on the outer side of the maintenance plate 5.

[0027] Please refer specifically to Figure 1 and Figure 2 , a shielding plate 3 protruding outward is integrally formed at the non-rotating end of the rotating door 2. The rotating door 2 in the closed state drives the shielding plate 3 to shield the insertion slot 4.

[0028] In this embodiment: When not under maintenance, the rotating door 2 is in the closed state. The rotating door 2 drives the shielding plate 3 to shield the insertion slot 4, avoiding dust or moisture from entering the distribution box 1 through the insertion slot 4 during daily use.

[0029] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
