Description

Button

Technical field

The utility model relates to a kind of button.

Background technology

CN00257358.X has announced a kind of " button ".It is comparatively laborsaving that its purpose provides a kind of pressing, and difficult the breaking of its lead coupling spring lamination damaged the button of phenomenon.Its technical scheme: this button is made up of in conjunction with the button and the lead coupling spring lamination that constitute a button body and a button outer cover, is that device is between the shell and PC plate of facility such as cell-phone or palmtop computer; The button body of this button is to be made as prominent grain of circular arc or protruded stigma in its downside central authorities, should the prominent grain of circle when desire is pressed this button or the arc awl end of protruded stigma, contact middle position sleekly in a lead coupling spring lamination.Its weak point: button is not dustproof, non-watertight, and button is short useful life.

The utility model content

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provides a kind of by increasing the elastic packing body structure, causes that button can prevent dust, waterproof, improves the button of push button longevity.

The purpose of this utility model can reach by following measure:

This button, the housing that comprises button, ccontaining this button, its special character is: described housing is a cup-shaped cavity, its bottom is provided with shell fragment, the shell fragment top is provided with button, described button is made up of a crosswise framework, its two shoulder is same plane with the housing top end wall respectively, and a coating button head and the elastic sealed body that outwards vertically bends respectively at its two shoulder are interposed in respectively between housing top end wall, button two shoulders and the pressing plate.

The purpose of this utility model can also reach by following measure:

Described shell fragment is made up of an arcuate tab.

Described elastic sealed body holds opening groove, the opening groove two ends of indent moulding from bottom to top to stretch out respectively therein by a plane and the elongated end parallel with end face formed.

The utility model has following advantage compared to existing technology:

1, button can dustproof and waterproof.

2, improve push button longevity.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

See also shown in Figure 1, this button, the housing 1 that comprises button 5, ccontaining this button 5, its housing 1 is a cup-shaped cavity, its bottom is provided with shell fragment 3, shell fragment 3 tops are provided with button 5, described button 5 is made up of a crosswise framework, and its two shoulder 51 is same plane with housing 1 top end wall respectively, and a coating button head 52 and the elastic sealed body 2 that outwards vertically bends respectively at its two shoulder 51 are interposed in respectively between housing 1 top end wall, button two shoulders 51 and the pressing plate 4.Described shell fragment 3 is made up of an arcuate tab.Described elastic sealed body 2 holds opening groove 21, opening groove 21 two ends of indent moulding from bottom to top to stretch out respectively therein by a plane and the elongated end 22 parallel with end face formed.

The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
