The mounting seat 41 and the fixing block 42 are respectively fixedly installed on the outer wall of the distribution box 1 and the inspection cabinet door 3. The mounting seat 41 is provided with a plurality of fixing rods 72. There are two of them, and a positioning rod 43 is fixedly provided inside the mounting seat 41, and the outer wall of the positioning rod 43 is rotatably connected to a guide plate 44, a guide groove 45 is provided inside the guide plate 44, a threaded rod 47 is provided inside the guide groove 45, and one end of the threaded rod 47 is fixedly connected to a diamond cap 46, a notch 49 is provided inside the fixing block 42, one end of the threaded rod 47 is connected to the inside of the notch 49, a pin 48 is provided inside the guide plate 44, and one end of the pin 48 is clamped on the fixing block 42.

[0026] By squeezing and connecting the inspection cabinet door 3 with the sealing ring piece 73 in the distribution box 1 using the sealing gasket 71 on the four fixing rods 72, the inspection cabinet door 3 and the distribution box 1 are relatively sealed when closed. By rotating the guide plate 44 on the outer wall of the positioning rod 43 in the mounting seat 41 to be parallel to the fixed block 42 on the inspection cabinet door 3, and then rotating the threaded rod 47 on the diamond cap 46 to connect it with the slot 49, when the diamond cap 46 is rotated to be perpendicular to the guide groove 45, the guide plate 44 is then positioned on the fixed block 42 using the pin 48, so that the inspection cabinet door 3 is relatively tightly closed while improving its sealing effect.

[0027] Preferably, the heat dissipation assembly 5 includes a filter plate 51, a mounting plate 53 and a motor 52. The filter plate 51 is fixedly clamped inside the distribution box 1. There are two mounting plates 53 and the mounting plates 53 are fixedly set on the inner wall of the filter plate 51. The motor 52 is set inside the mounting plate 53 and the output end of the motor 52 is connected to a screw rod 54. The outer wall of the screw rod 54 is threadedly connected to a positioning plate 55 and the other end of the positioning plate 55 is slidably connected to the outer wall of the slide rod 56. The two ends of the slide rod 56 are fixedly connected to the two mounting plates 53. A small motor 57 is fixedly set inside the positioning plate 55 and the output end of the small motor 57 is fixedly connected to a cooling fan 58.

[0028] By driving the motor 52 in the mounting plate 53, the positioning plate 55 on the screw rod 54 is driven to move, and at the same time, the other end of the positioning plate 55 slides on the slide rod 56, and at the same time, the small motor 57 is driven to drive the cooling fan 58 to rotate to speed up the heat removal speed inside the distribution box 1, so as to release the internal heat and effectively dissipate the heat.

When the inspection cabinet door 3 is closed, the guide plate 44 on the outer wall of the positioning rod 43 in the rotating mounting seat 41 is parallel to the fixing block 42 on the inspection cabinet door 3, and then the threaded rod 47 on the diamond cap 46 is rotated to connect with the notch 49. When the diamond cap 46 is rotated to be perpendicular to the guide groove 45, it stops rotating, and then the inspection cabinet door 3 is closed. The latch 48 positions the guide plate 44 on the fixed block 42, which makes it easier to close the inspection cabinet door 3 relatively tightly while improving its sealing effect.
