[0039] like Figure 3 to Figure 4 As shown, the shielding device 5 includes a fixed frame 51, which is fixedly connected to the cabinet 1. A rectangular frame 52 is detachably installed on the surface of the fixed frame 51. A dustproof net 53 is fixedly connected to the inner wall of the rectangular frame 52. A pull rod 54 is fixedly connected to the surface of the rectangular frame 52. When the electrical box is running, the controller 3 inside the cabinet 1 controls the passage of current, the controller 3 will generate heat, and air will pass through the ventilation holes 4 on the cabinet 1. Dust in the air will be blocked by the dustproof net 53, so that the hot air in the cabinet 1 can circulate, thereby dissipating heat in the cabinet 1. The dustproof net 53 used for a long time will age and needs to be replaced with a new one. The staff pulls the rectangular frame 52 in the fixed frame 51 through the pull rod 54 to pull the dustproof net 53 out of the fixed frame 51, and then inserts the rectangular frame 52 equipped with the new dustproof net 53 into the fixed frame 51. The surface of the fixed frame 51 is rotatably connected to the fixed block 55. The fixed block 55 is rotated downward, and the surface of the fixed block 55 is fixedly connected to the magnet 56. The surface of the rectangular frame 52 is fixedly connected to the magnetic sheet 57, which is blocked on the rectangular frame 52. The magnet 56 on the fixed block 55 is adsorbed on the magnetic sheet 57 on the rectangular frame 52. The surface of the rectangular frame 52 is fixedly connected to the sealing strip 58, and the sealing strip 58 on the rectangular frame 52 fits with the inner wall of the fixed frame 51.
[0040] In the embodiment of the utility model, when the electrical box is in operation, the controller 3 inside the cabinet 1 controls the passage of current, the controller 3 will generate heat, and air will pass through the ventilation holes 4 on the cabinet 1. Dust in the air will be blocked by the dustproof net 53, so that the hot air in the cabinet 1 can circulate, thereby dissipating heat in the cabinet 1. The dustproof net 53 used for a long time will age and needs to be replaced with a new one. The staff pulls the rectangular frame 52 in the fixed frame 51 through the pull rod 54 to pull the dustproof net 53 out of the fixed frame 51, and then inserts the rectangular frame 52 with the new dustproof net 53 into the fixed frame 51.

When the controller 3 in the cabinet 1 needs to be repaired, the staff opens the cabinet door 2, and after the cabinet door 2 rotates past the position of the latch 62, the latch 62 on the fixing plate 64 clamps the cabinet door 2 to limit the cabinet door 2. A spring 63 is sleeved on the surface of the latch 62, and one end of the spring 63 is fixedly connected to the fixing plate 64, and the other end of the spring 63 is fixedly connected to the limiting block 61.

The rubber sleeve 65 deforms with the expansion and contraction of the spring 63.
[0042] In the embodiment of the utility model, when the controller 3 in the cabinet 1 needs to be inspected, the staff opens the cabinet door 2. When the cabinet door 2 is against the latch 62, the spring 63 will stretch, and the rubber sleeve 65 will deform with the expansion and contraction of the spring 63. After the cabinet door 2 rotates past the position of the latch 62, the latch 62 on the fixing plate 64 will clamp the cabinet door 2 to limit the cabinet door 2.
[0043] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
