Embodiment 1

[0026] like figure 1 As shown, this embodiment provides a box body 3 and a box door that are matched; the box door includes an outer box door 4 and an inner box door 1; the box body 3 consists of an upper box surface, a lower box surface, a first box The side box surface, the second side box surface and the rear box surface are enclosed and formed; the inner box door 1 is hingedly connected to one side of the first side box surface, and the outer box door 4 is connected to the second side box surface. One side of the box surface is hingedly connected; a plane is formed between the outer box door 4 and the upper box surface, the lower box surface, the first side box surface and the second side box surface. The surfaces of the box body 3 and the inner box door 1 are coated with insulating paint.

[0027] Both the outer box door 4 and the inner box door 1 are provided with locks 5 .

[0028] The outer box door 4 is made of transparent material.

[0029] A transparent observati...

Embodiment 2

[0038] This embodiment provides a waterproof and rust-proof distribution box. The difference from Embodiment 1 is that the insulating varnish in this embodiment is made of the raw materials described in Table 1 in parts by weight.

[0039] Wherein, the waterproofing agent is trimethoxysilane.

[0040] The corrosion-resistant agent is a mixture of polyaspartic acid and fly ash, and the weight ratio of polyaspartic acid: fly ash is 0.4:1.

[0041] The flame retardant is antimony trioxide.

[0042] The ultraviolet absorber is UV-329.

[0043] The nano oxide is a mixture of nano calcium oxide, nano silicon dioxide and nano titanium dioxide, and the weight ratio of nano calcium oxide: nano silicon dioxide: nano titanium dioxide is 1:2.5:0.5.

[0044] The corrosion inhibitor is sodium mercaptobenzothiazole.

Embodiment 3

[0046] This embodiment provides a waterproof and rust-proof distribution box. The difference from Embodiment 1 is that the insulating varnish in this embodiment is made of the raw materials described in Table 1 in parts by weight.

[0047] Wherein, the waterproofing agent is triethoxysilane.

[0048] The corrosion-resistant agent is a mixture of polyaspartic acid and fly ash, and the weight ratio of polyaspartic acid: fly ash is 0.5:1.

[0049] The flame retardant is diammonium phosphate.

[0050] The ultraviolet absorber is UV-329.

[0051] The nano oxide is a mixture of nano calcium oxide, nano silicon dioxide and nano titanium dioxide, and the weight ratio of nano calcium oxide: nano silicon dioxide: nano titanium dioxide is 1:2.8:0.6.

[0052] The corrosion inhibitor is sodium mercaptobenzothiazole.

Abstract

The invention provides a waterproof and rust-proof distribution box, belonging to the technical field of distribution boxes, comprising a box body and a box door which are matched; the box door includes an outer box door and an inner box door; The inner box door is hingedly connected with one side of the first side box surface, and the outer box door It is hingedly connected with one side of the second side box surface; a plane is formed between the outer box door and the upper box surface, the lower box surface, the first side box surface and the second side box surface, and the box body Insulating paint is applied to the surface of the inner box and the door. The invention can effectively prevent rainwater from entering the inside of the distribution box along the gap between the box door and the box body. The insulating paint coated on the surface of the distribution box is waterproof and corrosion-resistant. After long-term sunlight and rain erosion, it shows good performance. Comprehensive performance, good protection effect.

Description

technical field [0001] The invention relates to the technical field of distribution boxes, in particular to a waterproof and rust-proof distribution box. Background technique [0002] Distribution box has become one of the necessary circuit safety protection products in household, industrial, commercial and other decoration. On the screen, a low-voltage power distribution device is formed. The integrated integrated distribution box that appears in the field and data mainly includes a cabinet, the main switch, wiring terminals, ammeter, voltmeter and capacitors located in the cabinet. During normal operation, the circuit can be switched on or off by means of manual or automatic switches. In the event of failure or abnormal operation, the circuit can be cut off or alarmed by means of protective appliances. By means of measuring instruments, various parameters in operation can be displayed, and some electrical parameters can also be adjusted to prompt or send signals for dev...
