  • Patent number: 9866659
    Abstract: 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.
