[0027] As Figure 1 — Figure 4As shown in the figure, the closing unit 200 includes two closing doors 201 movably arranged inside two sliding openings 102, and buffer pads 202 respectively fixedly connected to one end of the two closing doors 201. Through the buffer pads 202 arranged at the ends of the two closing doors 201, it is convenient to buffer and reduce noise when the closing doors 201 are closed.

[0028] As Figure 3 shown in the figure, the rolling unit 300 includes a fixed shaft 301 fixedly connected between the opposite inner wall surfaces of the arc-shaped rolling groove 105, a roller 302 sleeved on the outer surface of the fixed shaft 301, and a through hole 303 opened at one end of the roller 302. By rotating the roller 302 on the outer surface of the fixed shaft 301 inside the arc-shaped rolling groove 105, it assists the movement of the closing door 201, providing flexibility during opening and closing.

[0029] Among them, the inner width of the sliding opening 102 is adapted to the width of the closing door 201. The outer surface of the roller 302 is on the same horizontal plane as the top and bottom of the closing door 201.

The rotation of the lateral bevel gear 403 drives the two lead screws 404 to rotate synchronously on the opposite inner wall surfaces of the top cabinet 103 through meshing with the two vertical bevel gears 405. The synchronous rotation of the two lead screws 404 drives the two threaded blocks 406 to move synchronously on their outer surfaces, moving away from or approaching each other. The moving away from or approaching each other of the two threaded blocks 406 drives the two connecting sliders 407 to move synchronously inside the sliding through groove 104, moving away from or approaching each other. The moving away from or approaching each other of the two connecting sliders 407 drives the two closing doors 201 to move inside the sliding through opening 102 for opening and closing operations. The upper and lower ends of the closing door 201 are respectively in contact with the two rollers 302. The rollers 302 roll on the outer surface of the fixed shaft 301 inside the arc-shaped rolling groove 105 to assist the closing door 201 in opening and closing operations. This structure can automatically open and close the control box 101, facilitating the operation of the control device inside the control box 101, being beneficial to the control operation of the generator set safety chain, and enabling the control box 101 to have the effect of safety protection, preventing direct opening and causing damage to the control device, and having good practicability.
