Waterproof mobile phone protection case

Abstract

The invention discloses a waterproof mobile phone protection case which comprises a first housing, a second housing and a pair of U-shaped fasteners. A first peripheral portion of the first housing and the second peripheral portion of the second housing adhere to each other, the outer wall surface of the first housing is provided with snapping slots, the inner wall surface of each U-shaped fastener is provided with a snapping block, and the lower edge of each U-shaped fastener is also provided with a hook portion. When the first housing, the second housing and the fasteners are snapped, the snapping blocks are inserted into the snapping slots on the first housing and the hook portions hook the lower edge of the second housing tightly to clamp the seal structure of the adhesive portion for achieving the sealing. Therefore, when the waterproof mobile phone protection case is detached, the U-shaped fasteners are firstly unfastened from the both ends, and then the first housing and the second housing are separated. The detaching force cannot directly act on the first housing and the second housing, so that the first housing and the second housing can avoid being damaged into deformation and can be detached and reused repetitiously. The first housing and the second housing can be made of hard deformation-resistant materials, so that products have better structural strength.

Description

technical field [0001] The invention relates to the field technology of mobile phone accessories for daily necessities, in particular to a newly designed waterproof protective case for mobile phones. Background technique [0002] As we all know, mobile phones are one of the indispensable carry-on items in people's daily life in contemporary society. Traditional mobile phones used for communication have gradually expanded into all-round products integrating text messages, video calls, video playback, office notes, Internet access, and game terminals, such as iPhone series mobile phones. [0003] In the prior art, in order to avoid damage to the mobile phone due to collision, drop or water ingress, a mobile phone protective cover is usually provided outside the mobile phone to protect the mobile phone, especially a high-end mobile phone. At present, although there are mobile phone protective cases with waterproof protection function on the market, it is found that there are s...

Problems solved by technology

At present, although there are mobile phone protective cases with waterproof protection function on the market, it is found that there are still many deficiencies in its own structure and performance during actual use. Now its shortcomings are summarized as follows: On the one hand, the existing mobile phone protection The fastening structure of the upper and lower shells of the sleeve is unreasonable, and its fastening mechanism is directly extended from the peripheral parts of the first shell and the second shell. In this way, not only will the first shell and the second shell It is difficult to form, the structure of the forming mold is complicated, and the production cost is greatly increased; moreover, it becomes difficult to disassemble the first shell and the second shell after assembly, and it is necessary to use brute force to break apart when disassembling, and the fastening mechanism needs to be rigidly deformed. The fastening mechanism is easily damaged, and it is more likely to cause deformation of the first housing and the second housing, which is not suitable for repeated disassembly and assembly; Deformable materials need to be used, which reduces its structural strength and weakens its protective performance

On the other hand, the sealing and waterproof structure of the upper and lower shells of the existing mobile phone protective cover is unreasonable. It realizes sealing by setting movable gaskets in the grooves. Its sealing performance
