[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model.

[0021] Next, with reference to the accompanying drawings, a waterproof and dustproof S-shaped shutter for an outdoor electrical box according to an embodiment of the present invention will be described. As Figure 1 - Figure 7 shown, the waterproof and dustproof S-shaped shutter for an outdoor electrical box includes a frame 1 and shutter blades 2. The frame 1 is fixed to the outdoor electrical box, and the shutter blades 2 are arranged and installed inside the frame 1. The shutter blades 2 are in an "S" shape. The waterproof and dustproof S-shaped shutter for an outdoor electrical box further includes: a dustproof device provided on the shutter blades 2, which can prevent dust from the outside from entering the outdoor electrical box; an adjusting device provided on the frame 1, which can adjust the angle of the shutter blades 2.

[0022] As Figure 3 、 Figure 6 and Figure 7 shown, the waterproof and dustproof S-shaped shutter for an outdoor electrical box according to an embodiment of the present invention includes a dustproof device. The dustproof device includes a movable plate 4, a dustproof net 5, and a permanent magnet 6. The movable plate 4 is slidably installed at one end of the shutter blade 2. Springs are provided at both ends of the movable plate 4 to connect the shutter blade 2. One end of the dustproof net 5 is connected to the middle of the movable plate 4, and the other end is connected to the shutter blade 2. A slot is provided on the shutter blade 2 for placing the dustproof net 5. The permanent magnet 6 is provided at the other end of the shutter blade 2, and the permanent magnet 6 can attract the movable plate 4.

[0023] In a specific embodiment: during use, the movable plates 4 are arranged obliquely inside the frame 1, thereby preventing rainwater from entering and causing damage to the electrical box.

[0024] As Figure 3 、 Figure 4 and Figure 5 shown, the waterproof and dustproof S-shaped shutter for an outdoor electrical box according to an embodiment of the present invention includes an adjusting assembly. The adjusting assembly is composed of a slider 3. The slider 3 is provided inside the frame 1. A convex block is provided above the slider 3, and a corresponding chute is provided on the frame 1. A convex column is provided in the middle of the shutter blade 2, and the shutter blade 2 is installed on the frame 1 through the convex column. Another convex column is provided on both sides of the shutter blade 2, and the shutter blade 2 is slidably connected to the slider 3 through the convex column. A corresponding arc-shaped chute is provided on the frame 1, and a corresponding straight groove is provided on the slider 3.

[0025] In a specific embodiment: during adjustment, the angle of the shutter blade 2 is adjusted by sliding the slider 3.

[0026] When the shutter blades 2 are inclined and the upper and lower shutter blades 2 are in contact with each other, the permanent magnet 6 of the upper shutter blade 2 attracts the movable plate 4 of the lower shutter blade 2, thereby sealing the S-shaped shutter and preventing water and dust from entering.

[0027] When the shutter blades 2 are inclined and there is a certain gap between the upper and lower shutter blades 2, the permanent magnet 6 of the upper shutter blade 2 attracts the movable plate 4 of the lower shutter blade 2, causing the movable plate 4 to slide out the dustproof net 5, thereby ensuring ventilation and heat dissipation while preventing dust from the outside from entering the electrical box.

[0028] When the window leaf 2 is tilted to leave a large range of gaps between the upper and lower window leaves 2, the permanent magnet 6 on the upper window leaf 2 cannot attract the movable plate 4 on the lower window leaf 2, so that the S-shaped shutter can dissipate heat through ventilation to the greatest extent.

[0029] Working principle: During use, the movable plates 4 are arranged obliquely in the frame 1 to prevent rainwater from entering the electric box. During adjustment, the angle of the window leaf 2 is adjusted by sliding the slider 3. When the window leaf 2 is tilted and the upper and lower window leaves 2 come into contact with each other, the permanent magnet 6 on the upper window leaf 2 attracts the movable plate 4 on the lower window leaf 2, so that the S-shaped shutter is sealed to prevent water and dust. When the window leaf 2 is tilted to leave a certain gap between the upper and lower window leaves 2, the permanent magnet 6 on the upper window leaf 2 attracts the movable plate 4 on the lower window leaf 2, causing the movable plate 4 to slide out the dust-proof net 5, so that the S-shaped shutter can prevent external dust from entering the electric box while ensuring ventilation and heat dissipation. When the window leaf 2 is tilted to leave a large range of gaps between the upper and lower window leaves 2, the permanent magnet 6 on the upper window leaf 2 cannot attract the movable plate 4 on the lower window leaf 2, so that the S-shaped shutter can dissipate heat through ventilation to the greatest extent.
