[0040] like Figures 1 to 6 As shown, a dustproof device for a metal control box includes a control box 1 and multiple dustproof devices 2, and the multiple dustproof devices 2 are arranged outside the control box 1:

[0041] The outer surface of the control box 1 is provided with a plurality of heat dissipation slots 10, and a heat dissipation mesh plate 101 is provided in the heat dissipation slots 10; wherein, the dustproof device 2 is provided on the outer side of the heat dissipation slots 10;

[0042] A lifting partition 102 is provided on the side of the heat dissipation mesh plate 101 close to the dustproof device 2, and a lifting slot 103 is provided on the top of the heat dissipation tank 10 to cooperate with the lifting partition 102;

[0043] Two lifting clips 104 are fixedly mounted on the top of the lifting partition 102. The other ends of the lifting clips 104 are each mounted with a paddle 105. A lifting slot 2 106 is formed on the upper end of a side surface of the control box 1 on which the heat dissipation slot 10 is formed, and the lifting slot 2 106 is connected to the lifting slot 1 103. The paddle 105 is bonded to the lifting slot 1 103.

[0044] The lifting clip 104 is made of a soft material, such as rubber;

[0045] Among them, the paddle 105 is fixed to the lifting groove 103 by bonding, specifically, tape or Velcro can be used, so during the height adjustment process of the lifting partition 102, the paddle 105 can be easily separated from the lifting groove 103 to adjust the height of the lifting partition 102.

[0046] like Figures 7 to 12 As shown, the dustproof device 2 is provided in multiple pieces, the dustproof device 2 is provided outside the control box 1, and the dustproof device 2 is provided outside the heat dissipation slot 10;

[0047] The dustproof device 2 includes a rectangular mounting frame 21 and a dustproof screen 22 disposed within the rectangular mounting frame 21. The rectangular mounting frame 21 is disposed outside the heat sink 10 and is fixed to the control box 1 by bolting and / or welding.

[0048] The inner surface of the rectangular mounting frame 21 is covered with an elastic sealing layer 23, and the front and rear ends of the dust screen 22 are in contact with the elastic sealing layer 23, thereby ensuring the sealing between the dust screen 22 and the left and right ends of the rectangular mounting frame 21;

[0049] During the dust cleaning process on the surface of the dustproof screen 22, the lifting partition 102 can be placed between the heat dissipation screen 101 and the dustproof screen 22 to prevent dust from entering the heat dissipation screen 101; after cleaning, the lifting partition 102 can be raised to a certain height and away from the heat dissipation screen 101;

[0050] An elastic sealing band 24 is connected to both the upper and lower ends of the side surface of the dust screen 22 close to the control box 1, and the other end of the elastic sealing band 24 is fixedly mounted on the rectangular mounting frame 21. Specifically, the other end of the elastic sealing band 24 located at the upper end of the side surface of the dust screen 22 close to the control box 1 is fixedly mounted on the upper end of the interior of the rectangular mounting frame 21; the other end of the elastic sealing band 24 located at the lower end of the side surface of the dust screen 22 close to the control box 1 is fixedly mounted on the lower end of the interior of the rectangular mounting frame 21.

[0051] The elastic sealing band 24 is an elastic band, which can be compressed or stretched during the rotation of the dust screen 22, thereby ensuring the sealing between the dust screen 22 and the upper and lower ends of the rectangular mounting frame 21 during the rotation of the dust screen 22;

[0052] The front and rear ends of the dust screen 22 are fixedly connected to a rotating column 1 221. The other end of the rotating column 1 221 passes through the elastic sealing layer 23 and the rectangular mounting frame 1 21 in sequence. The rotating column 1 221 passes through the elastic sealing layer 23 and the rectangular mounting frame 1 21 and is integrally provided with a rotating column 222 at one end. The other end of the rotating column 222 is fixedly mounted with a rotating disk 223.

[0053] The rotating disk 223 is provided with anti-slip grooves on the outside to facilitate rotation;

[0054] The front and rear sides of the rectangular mounting frame 1 21 are provided with grooves 211, an adjustment plate 212 is fixedly installed in the groove 211, and a rotation hole 213 is provided on the front side of the adjustment plate 212 to match the rotation column 222;

[0055] Since the diameter of the second rotating column 222 is larger than that of the first rotating column 221, dust is prevented from entering the rectangular mounting frame 1 21 through the gap between the second rotating column 222 and the adjustment plate 212;

[0056] One side of the adjustment plate 212 is in close contact with the control box 1. A threaded hole 214 is formed on the other side of the adjustment plate 212. A locking bolt 215 is threadedly connected to the threaded hole 214. One end of the locking bolt 215 passes through the threaded hole 214 and is in close contact with the second rotating column 222.

[0057] During this process, the rotation angle of the dust screen 22 can be adjusted by rotating the rotating disk 223. After the adjustment is completed, the locking bolt 215 is used to lock and fix it.

[0058] A cleaning scraper 25 is provided at one end of the rectangular mounting frame 21 away from the heat dissipation slot 10 .

[0059] A handle 251 is provided on the other side of the cleaning scraper 25 ; the cleaning scraper 25 is used to clean the surface of the dustproof screen 22 .

[0060] The utility model provides a dustproof device for a metal control box, in which a dustproof device 2 is arranged outside a heat dissipation mesh plate 101, and a dustproof mesh plate 22 is arranged in the dustproof device 2. The inclination angle of the dustproof mesh plate 22 can be adjusted, thereby preventing external dust from directly adhering to the heat dissipation mesh plate 101, thereby ensuring that the metal control box has a dustproof effect; a cleaning scraper 25 is provided to clean the surface of the dustproof mesh plate 22.

[0061] In the present invention, an elastic sealing layer 23 and an elastic sealing belt 24 are provided to ensure sealing between the periphery of the dustproof screen 22 and the rectangular mounting frame 1 21 when the angle of the dustproof screen 22 is adjusted by rotation.
