Waterproof box body

Abstract

The invention relates to a waterproof box body which comprises a body and an elastic ring body. The elastic ring body is sheathed on the body, and a concave surface is arranged on the inner side of the elastic ring body, wherein the elastic ring body is in contact with and presses the surface on the outer side of the body by the concave surface on the inner side. The waterproof box body can eliminate a waterproof adhesive through the waterproof structure, thereby achieving the effects of simplifying the process and enhancing the qualification ratio of a product. In addition, an upper cover and a lower cover of the waterproof box body only need a small number of screws for locking and attaching through the waterproof structure, thereby reducing the deformation problem of the structure in the prior art due to the locking and the attaching of the screws; and the precision errors at the junctions of assembly parts also allow the greater difference and avoid affecting the waterproof function.

Description

technical field [0001] The invention relates to a waterproof box body, and in particular to a waterproof box body with high water resistance. Background technique [0002] With the advancement of science and technology, today's technological products are changing with each passing day, and their functions are getting more and more, so there are more and more parts inside the corresponding device; the size is getting smaller and smaller, so the corresponding parts inside the device must also be Smaller and smaller, under this demand, the requirements for the design of the external casing of the device are also higher and higher, and the requirements for waterproofing are also higher and higher. [0003] see figure 1 . figure 1 Shown is a sectional view of a waterproof box body in the prior art. Such as figure 1 As shown, the waterproof box body 5 includes an upper cover 50 and a lower cover 52 , and the upper cover 50 and the lower cover 52 are locked by screws 54 . Due ...

AI Technical Summary

Problems solved by technology

However, due to the limited compression life of the waterproof adhesive, it may not be suitable for upper and lower covers that need to be disassembled frequently.

Secondly, when the combined surface of the upper and lower covers is a vertical surface or a curved surface, because the angle of the vertical surface or curved surface is too large, it is impossible to apply waterproof glue on the vertical surface or curved surface 64, 74

Even if rubber is used, the waterproof function cannot be achieved because the rubber has no lateral locking force, so it cannot be designed for waterproofing
