[0009] Figure 2 It is a partial structural schematic diagram of the utility model;

[0010] Among them, the switch device 100; the box body 1, the water retaining convex ring 11, the water-isolating convex edge 12, the inclined edge 13, the cover edge 14, the conical surface 15, the leakage hole 151; the mounting plate 2; the inner box door 3, the operation port 31; the outer waterproof door 4; the sealing ring 5. DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] like Figure 1 and 2 As shown, a double-layer protection distribution box includes a box body 1 and a box door. An opening is formed in the front of the box body 1, and a mounting plate 2 is provided at the rear of the box body 1. The mounting plate 2 is used to install the switch device 100. The box door is hinged on the right front side of the box body 1. These structures are the same as the prior art.

[0013] The improvement of this product is that the box door includes an inner box door 3 and an outer waterproof door 4, and the inner box door 3 and the outer waterproof door 4 are both hinged to the right side of the box body 1. The inner wall of the box body 1 forms a water-blocking convex ring 11 near the opening, thereby blocking the rainwater flowing into the box body 1. The inner box door 3 is inserted into the water-blocking convex ring 11, that is, the outer edge of the inner box door 3 is close to the inner wall of the water-blocking convex ring 11, and the front of the box body 1 is located at the outer periphery of the opening to form a water-blocking convex edge 12, and an inclined edge 13 inclined inwardly is formed between the water-blocking convex edge 12 and the water-blocking convex ring 11. The outer periphery of the outer waterproof door 4 forms a cover edge 14, which is set on the outer periphery of the water-blocking convex edge 12, and the inner wall of the cover edge 14 is provided with a sealing ring 5, and the inner box door 3 is provided with an operation port 31 for convenient operation at the position facing the switch device 100. The outer waterproof door 4 is equipped with a lock, and the inner box door 3 is provided with a handle for easy use. The lock and the handle are both existing parts.

[0014] In addition, a conical surface 15 is formed on the inner bottom surface of the box body 1 , and the conical surface 15 is concave from the periphery to the middle to form a cone, and a water leakage hole 151 is provided in the middle of the conical surface 15 .

[0015] Moreover, an elastic pressing block is provided on the surface of the inner box door 3 close to the switch device 100. The elastic pressing block is a rectangular foam block and is glued to the inner box door 3 by glue. The elastic pressing block presses the switch device 100.

[0016] When in use, the rainwater box 1 will first be blocked by the outer waterproof door 4 and the water-proof convex edge 12. The water-proof convex edge 12 and the sealing ring 5 are pressed tightly to further play a water-proof role, and the sealing ring 5 has a good sealing effect; afterwards, even if rainwater seeps in, the rainwater on the upper part of the box 1 flows from the inclined edge 13 to the water-proof convex ring, and flows downward, and the rainwater flows downward and flows outward from the inclined edge 13 at the bottom of the box 1; even if the rainwater enters the box 1, it will still gather on the conical surface 15, and then be discharged from the leakage hole 151 to the outside of the box 1. The inner box door 3 and the outer waterproof door 4 realize double protection, which is not only waterproof, but also has good anti-collision effect, and the elastic pressure block can also play the role of anti-collision buffer.

[0017] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
