[0033] The structure provided by the present utility model will be explained and described in detail below with reference to the accompanying drawings of the specification.

[0034] Referring to Figures 1 to 7 as shown, this embodiment specifically discloses a waterproof distribution box applied to a shelter, which includes a box body 1, a box cover 2 and a sealing strip 4. An accommodating cavity 15 with an opening at the front is formed inside the box body 1. A plurality of electrical components 3 are installed in the accommodating cavity 15. The electrical components 3 include relays, ammeters, terminal blocks, capacitors, circuit breakers, switches, etc., which will not be specifically described here. The box cover 2 is hinged to one side of the box body 1 for opening or closing the opening of the accommodating cavity 15;

[0035] Combining Figure 6 and Figure 7As shown, the front of the box body 1, i.e., the upper and lower sides and the left and right sides, are all extended toward the center of the opening to form a first flange 11, the end of the first flange 11 is bent toward the side away from the box body 1 to form a second flange 12, and the end of the second flange 12 is bent toward the side away from the center of the opening to form a third flange 13, and the first flange 11, the second flange 12 and the third flange 13 together form a waterproof groove 14; that is, in this embodiment, four first flanges 11 are formed around the opening of the box body 1, and the four first flanges 11 are sequentially connected end to end. Similarly, the four second flanges 12 are connected end to end in sequence, and can also be formed as one piece; the four third flanges 13 are connected end to end in sequence, and can also be formed as one piece, so as to form a protruding waterproof groove 14 on the front side of the box body 1; the cross-sectional profile of the waterproof groove 14 located at the upper part of the opening is basically U-shaped, and the cross-sectional profile of the waterproof groove 14 located at the lower end of the opening is basically n-shaped, the waterproof groove 14 on the left side is roughly a U-shaped structure rotated 90° counterclockwise, and the waterproof groove 14 on the right side is roughly a U-shaped structure rotated 90° clockwise;

[0036] The box cover 2 includes a cover body 21, and the four sides of the cover body 21 are vertically connected to a first rib 22 extending toward one side of the box body 1, and the end of the first rib 22 is vertically connected to a second rib 23 extending inwards;

[0037] The sealing strip 4 is attached to the periphery of the cover body 21 facing the box body 1, and can be fixed by gluing;

[0038] When the box cover 2 closes the opening of the accommodating cavity 15, the first flange 11 and the second rib 23 fit each other, and the second rib 23 is located in the waterproof groove 14; the end of the third flange 13 abuts against the sealing strip 4; that is, the combination Figure 6 It can be seen that the inward extension width of the second flange 22 is smaller than the inward extension width of the first flange, and the end of the second flange 22 is higher than the end position of the third flange 13 to avoid obstruction when the box cover 2 is closed; the end of the third flange 13 is set in contact with the sealing strip 4 to ensure the sealing effect.

[0039] In this embodiment, a plurality of retaining edges are provided on the box cover 2 to achieve a preliminary waterproof and rainproof effect. At the same time, a plurality of flanges are provided at the opening of the box body 1 to form a waterproof groove structure protruding from the box body 1. When rainwater enters from the gap between the box body 1 and the box cover 2, it can directly flow into the waterproof groove and flow down along both sides of the waterproof groove to avoid entering the interior of the box body 1. A sealing strip 4 is also provided in the box cover 2 to further prevent rainwater from entering the interior of the box body 1, thereby effectively improving the waterproof performance of the distribution box and ensuring the normal use of internal electrical components.

[0040] In some embodiments, the included angle between the second flanging 12 and the third flanging 13 is 90° to 150°, preferably, the included angle between the second flanging 12 and the third flanging 13 is 120° to 130°. Within this angle range, the waterproof groove 14 can have a rain shielding effect with a wider angle, and at the same time, it will not be tilted too much, causing rainwater to seep in along the edge of the third flanging 13 and flow into the box body.

[0041] In some embodiments, the box body 1, the first flanging 11, the second flanging 12 and the third flanging 13 are integrally formed; the cover body 21 and the first baffle 22, the second baffle 23 are integrally formed, so as to improve the overall structural strength of the waterproof distribution box, and the integral forming has better sealing performance to ensure the waterproof effect.

[0042] In some embodiments, a plurality of waterproof connectors 5 are arranged at the bottom of the box body 1; the incoming and outgoing lines of the distribution box can all pass through the waterproof connectors 5 for incoming and outgoing lines, further improving the overall sealing and waterproof performance of the distribution box. At the same time, arranging the incoming and outgoing lines at the bottom can also reduce external interference, etc.
