摘要： A waterproofing structure including a first casing, a waterproof pad, a second casing, and two pinch strips. Two first guide grooves and two second guide grooves are defined at either side of both casings. Each pinch strip is fitted and fastened to one first guide groove and one second guide groove to assemble and hold together the first and second casings, and so compressing the waterproofing pad between the two casings. Uniform pressure is applied to the waterproof pad at all points. The entire engagement section does not need screws, thus saving screwing time, and improving assembly efficiency. A mobile phone is also disclosed, the mobile phone has a complete sealing and waterproofing, and an assembly efficiency is improved.

摘要： A waterproof presskey structure includes a shell, a button or presskey, and an elastic element. The elastic element and the shell can be assembled together with gum, the presskey is movably assembled to the shell and matches with the elastic element. The elastic element comprises a tubular structure having an elastic wall. The elastic wall is arched, and the elastic wall projects out towards within the tubular structure. For the arched elastic wall stretches under pressure from the button or presskey, an assembly of the elastic element and other parts is not affected, the elastic element cannot be separated from the shell due to the gum failing, and water resistance between the presskey and the shell is increased.

摘要： A mobile phone proofed against water, dust, and physical shocks (tri-proofed) has a structure comprising a first casing, a second casing, and a third casing. The first casing is provided with protrusions, and the third casing is provided with convex blocks. The second casing is provided with a first groove for a protrusion, and is provided with a second groove for a convex block. The protrusions and the convex blocks are both interference fits in the grooves. Moreover, the second casing also includes cosmetic surfaces. The first casing and the third casing have outer surfaces and each cosmetic surface protrudes out of the outer surfaces. The cosmetic surfaces are in first contact when the mobile phone is dropped. Waterproofing, dustproofing, and shockproofing are simultaneously achieved with the single second casing structure.
