[0020] The utility model will be further described in detail in combination with the drawings and specific embodiments:

[0021] As Figure 1 , 2The dustproof device for a distribution box comprises a distribution box body 1, a wire inlet 2 and a wire outlet 3, a dustproof assembly is arranged on the outer side of the first wire inlet 2 and the first wire outlet 3, the dustproof assembly comprises a placing box 4, a plurality of sliders 5 capable of sliding towards each other are slidably connected in the placing box 4, a dustproof sponge 6 is arranged at the end of the slider 5, a first sliding groove 7 is formed in the middle of the slider 5, a limiting rod 8 is slidably connected in the first sliding groove 7, the limiting rod 8 extends outwards at both ends and penetrates through the second sliding groove 9 formed on the left and right sides of the placing box 4, and a compression spring 10 is arranged between the slider 5 and the placing box 4.

[0022] As shown in Figure 3 , 5 A pull ring 11 is arranged at the end of the limiting rod 8.

[0023] As shown in Figure 3 , 5 One end of the compression spring 10 is connected and fixed with the slider 5, and the other end is connected and fixed with the bottom of the placing box 4.

[0024] As shown in Figure 1 , An end cover 12 is arranged on the upper part of the placing box 4.

[0025] As shown in Figure 1 , 4 An opening 13 for wire inlet and wire outlet is formed on the end cover 12 and the placing box 4 respectively.

[0026] As shown in Figure 1 , The placing box 4 is connected and fixed with the distribution box body 1 through bolts.

[0027] The implementation principle of the dustproof device for a distribution box is as follows:

[0028] When the cable is not inserted into or out of the distribution box body 1, the dustproof sponges 6 on the adjacent and opposite sliders 5 are in close contact with each other under the elastic force of the compression spring 10;

[0029] When the cable needs to be inserted into or out of the distribution box body 1, the corresponding pull ring 11 on the limiting rod 8 on the two sides of the placing box 4 at the wire inlet 2 or the wire outlet 3 is pulled to move to the left and right sides, when the pull ring 11 is pulled to the left and right sides, the limiting rod 8 will move the corresponding slider 5 to the left and right sides, so that the wire inlet 2 or the wire outlet 3 is unobstructed with the opening 13, in order to facilitate the cable to be inserted into or out of the distribution box body 1, the compression spring 10 on the corresponding slider 5 will be squeezed to generate a rebound force when the corresponding slider 5 moves to the left and right sides;

[0030] After the cable is inserted into or out of the distribution box body 1, the pull ring 11 is released, and the corresponding slider 5 is pushed by the elastic force of the compression spring 10 and is folded to the middle of the placing box 4, and when the slider 5 is folded to the middle of the placing box 4, the dustproof sponge 6 is tightly attached to the cable;

[0031] When the dustproof sponge 6 is tightly attached to the cable, the dustproof sponge 6 is deformed due to the characteristics of the dustproof sponge 6 being extruded by the cable, so that the dustproof sponge 6 is tightly attached to the cable and covers the cable, effectively preventing dust or some organisms from entering the distribution box body 1 through the cable inlet 2 and the cable outlet 3, ensuring the stability and reliability of the dustproof assembly as a whole, and providing continuous and effective dustproof protection for the distribution box.

[0032] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection of the utility model is defined by the appended claims and their equivalents.
