Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1-4, a novel moisture-proof low-voltage distribution box comprises a box body formed by splicing an upper side plate 2, a lower side plate 3 and a back plate 1, wherein a fixing part 5 is arranged on the back plate 1, and a plurality of waterproof glan heads 6 are arranged on the upper surface of the upper side plate 2.
A dehumidifier 14, a temperature and humidity sensor 12 and a temperature and humidity control host 13 are arranged in the distribution box, the temperature and humidity sensor 12 is connected with the temperature and humidity control host 13, and the temperature and humidity control host 13 is connected with an electric control part of the dehumidifier 14; be equipped with the sealed pad 9 of foaming on the inner wall of the door plant 8 of block terminal, still be equipped with stainless steel fixing bolt 11 on the door plant 8, stainless steel fixing bolt 11 and door plant 8 between be equipped with and be annular silica gel sealed pad 10.
The corresponding position of the box body is provided with a pi-shaped silica gel pressing strip 7 matched with the foaming sealing gasket 9, the cross section of the pi-shaped silica gel pressing strip 7 is pi-shaped, and the middle part of the pi-shaped silica gel pressing strip is provided with a notch.
The tip of going up side panel 2, lower side panel 3 and backplate 1 be equipped with a plurality of double-screw bolts 4, a plurality of double-screw bolts 4 constitute the joint groove with the protruding portion of going up side panel 2, lower side panel 3 and backplate 1 tip, pi type silica gel layering 7 joint in the joint inslot.
After the high-strength cold-rolled steel sheet metal is molded, the back plate 1, the upper side plate 2, the lower side plate 3, the studs 4 and the fixing pieces 5 are welded together in sequence, and the sheet metal production is completed through surface plastic spraying treatment.
