[0027] See also Figure 1-8 , the utility model provides a technical solution:

[0028] The front and rear maintenance power control box includes a box body 1, a clamping plate 2 is fixedly connected to the outer side of the box body 1, the outer side of the clamping plate 2 is tightly attached to the bracket 3, a first threaded hole 4 is fixedly connected to the inner side of the bracket 3, a second threaded hole 5 is slidably connected to the inner side of the bracket 3, a pin 6 is fixedly connected to the outer side of the bracket 3, a pin hole 7 is provided on the inner side of the clamping plate 2, a threaded hole 8 is provided on the inner side of the clamping plate 2, a limiting hole 9 is provided on the inner side of the clamping plate 2, and a captive screw 10 is spirally connected to the inner side of the first threaded hole 4.

[0029] The limiting hole 9 is interconnected with the inner side of the first threaded hole 4, and the captive screw 10 slides inside the limiting hole 9, which is convenient for using the captive screw 10 to complete the disassembly, installation and maintenance work of the box body 1 and the bracket 3 from the front of the power control box; the threaded hole 8 is interconnected with the second threaded hole 5, and the captive screw 10 can be spirally connected with the threaded hole 8, and the captive screw 10 slides inside the second threaded hole 5, which is convenient for the captive screw 10 to disassemble, install and maintain it from the back of the power control box; the pin 6 is engaged with the inner side of the pin hole 7, and the pin hole 7 is arranged in the middle position of two adjacent threaded holes 8, so that the two can be positioned and restricted before the power control box and the bracket 3 are connected by the captive screw 10; the number of threaded holes 8 and the limiting holes 9 is the same, and the threaded holes 8 are arranged next to the limiting holes 9, which is convenient for disassembly, installation and maintenance of the power control box on the bracket 3 from different directions.

[0030] Working process: When using the power control box, place the box body 1 in the middle of the bracket 3, and make the clamping plate 2 fixedly connected to the outside of the box body 1 clamped in the clamping groove inside the bracket 3, and at the same time, the pin hole 7 fixedly connected to the outside of the bracket 3 and the pin hole 7 inside the clamping plate 2 clamped with each other, so as to play a certain stable supporting role before the box body 1 and the bracket 3 are connected together by the captive screw 10, and then the captive screw 10 is inserted from the limiting hole 9 opened on the inner side of the clamping plate 2, and the captive screw 10 is allowed to enter the hole on the inner side of the bracket 3 connected with the limiting hole 9, and then the captive screw 10 is blocked by the first threaded hole 4 set on the inner side of the bracket 3, and then the captive screw 10 is rotated so that the captive screw 10 is spirally connected with the first threaded hole 4 on the inner side of the bracket 3, so that the box body 1 can be fixed on the bracket 3 from the front of the power control box, and the captive screw 10 and the first threaded hole are loosened.
