Housing with portable snap-on three-proof structure

Abstract

The invention relates to a shell with a portable snap-on three-proof structure, which includes an upper shell and a lower shell. The upper shell and the lower shell are connected and combined through the snap-on three-proof structure; the snap-on three-proof structure includes The buckle cavity, the buckle platform and the buckle pressure plate arranged on the inner wall of the lower shell; the buckle cavity is composed of the upper retaining wall and the side wall, and the bottom of the buckle cavity is open; the top of the buckle platform is provided with a matching with the lower edge of the side wall Steps, the upper part of the buckle platform is embedded in the opening of the buckle cavity, the top of the buckle platform forms a middle retaining wall to block the opening of the buckle cavity, and the lower part of the buckle platform is provided with a small chamber with a bottom opening; It is arranged on the bottom surface of the lower shell. There is a hook-shaped buckle on the fastening pressure plate. The bayonet of the hook-shaped buckle faces outward. There is a buckle edge on the bottom of the small chamber. After the hook-shaped buckle is completely pressed into the small chamber , the bayonet of the hook-shaped buckle is correspondingly embedded in the side of the buckle. The invention has ingenious structure, reasonable design, small size, good three-proof effect, high reliability and low cost.

Description

technical field [0001] The invention relates to a casing with a three-proof structure, in particular to a casing with a portable buckle three-proof structure. Background technique [0002] With the improvement of people's living standards, there are higher requirements for material and civilized life outside of amateur life. Therefore, in recent years, outdoor adventure sports, underwater sports, desert car and motorcycle races and other outdoor sports have become more and more popular among consumers. However, these outdoor sports will inevitably encounter harsh environments such as rain, sand, dust, and wetlands. Three-proof (dustproof, waterproof, shockproof) requirements are put forward for the products carried by athletes. Correspondingly, there are more and more demands for three-proof products to meet these outdoor sports. With its professional waterproof, dustproof and excellent anti-drop and anti-rolling performance, the three-proof products can be used in extremel...

Problems solved by technology

[0003] However, the applicant found through research that the traditional three-proof structure design of products currently on the market has the following shortcomings: the three-proof design of existing products mostly uses O-RING rubber rings, dispensing, and U-shaped structures for plastic mating surfaces. Design with plastic shell snap fit and compression

This design can not help but increase the cost of mold manufacturing, affect production efficiency, and is not convenient for automated mass production. Moreover, the O-RING rubber ring used in it is easy to age in the acid-base environment of humid gas and loses waterproof and moisture-proof effects, resulting in product Cannot be used normally, affecting the user's sports enjoyment
