The names of the parts are as follows in figure：

Casing 101, seal rubber sleeve 102, button 103, key cap of key set 1031, button axle 1032, spring 104, FPC components 105, clamp spring 106, spring eye 107.

Specific implementation mode

The utility model is described further below in conjunction with the accompanying drawings.

As shown in Figure 1A to Fig. 1 D, a kind of key water-proof structure only need to open a circular hole on casing 101, i.e., at switch Key hole, 103 waterproof of button need to only carry out this hole waterproofing design can, at this hole design a softwood matter seal rubber sleeve 102, to ensure that liquid-state silicon gel may be used in service life, seal rubber sleeve 102.

The seal rubber sleeve 102 can be fixed on casing 101 with in-mould injection in button axle 1032 or by close-fitting and dispensing On, when 102 in-mould injection of seal rubber sleeve is in button axle 1032, seal rubber sleeve 102 is interference fitted anti-to realize with key hole Water function, when button 103 presses, seal rubber sleeve 102 has relative motion with the key hole of button axle 1032 and casing 101.

When seal rubber sleeve 102 is fixed on by close-fitting and dispensing on casing 101, button axle 1032 and seal rubber sleeve 102 Interference fit, when button 103 presses, button 103 has relative motion with seal rubber sleeve 102.

Because seal rubber sleeve 102 has interference fit, there are larger resistance, the elastic force of normal condition lower switch that can not allow Button 103 is sprung back.Key hole both sides are equipped with the spring 104 of antirust, to the generation pressure of spring 104 when button 103 pushes, unclamp The pressure is used to offset the resistance that the interference fit of seal rubber sleeve 102 generates when button 103, and elp button 103 is sprung back.

Button axle 1032 is equipped with groove and is packed into clamp spring 106 in groove after button 103, spring 104 are packed into casing, should Clamp spring 106 prevents button 103 from falling off with casing 101.

Each key switch only need to open a through-hole in corresponding position, which passes through flexible glue（It is recommended as liquid-state silicon gel）It is close Seal waterproof；Key cap of key set 1031 is metal material, and complete machine is packed on the outside of casing.

As shown in Fig. 3 A, Fig. 3 B, Fig. 3 C, Fig. 3 D, a round tube hole is opened on casing at switch, which matches with seal rubber sleeve It closes, which opens spring eye（Blind hole）.

As shown in figure 4, the spring is antirust spring, it is mounted in key hole both sides or unilateral side（Volume key can basis when designing It needs to do unilateral side）, pressure is generated to spring when button pressed, the pressure is for offsetting seal rubber sleeve interference fit when unclamping button The resistance of generation, elp button rebound.Improve the feel of Waterproof push-button.

As fig. 5 a and fig. 5b, which is that the clamp spring is caught in button by stainless steel after being packed into button and spring In axial trough, prevent button from falling off with casing.

As shown in Fig. 6 A to Fig. 6 E, which is metal material, is machined with blind hole for being packed into spring, is machined on axis Card slot is used for assembling jump ring, prevents button from falling off with casing.

As shown in Fig. 7 A to Fig. 7 E, which is metal material, is machined with blind hole for being packed into spring, is machined on axis Card slot is used for assembling jump ring, prevents button from falling off with casing.

As shown in Fig. 8 A to Fig. 8 C, which is metal material, is machined with blind hole for being packed into spring, is machined on axis Card slot is used for assembling jump ring, prevents button from falling off with casing.

As shown in Fig. 9 A to Fig. 9 C, which is routine FPC components.

Such as Figure 10, for utilization of the key water-proof structure in mobile phone.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard To belong to the scope of protection of the utility model.
