Abstract
The utility model relates to the field of instruments, and especially relates to a fully-waterproof key combination. A key comprises an annular wall which comprises a projection, and the projection serves as a clamping and fixing part. A key hole comprises an opening, and the periphery of the opening is provided with a hole wall. The hole wall can be embedded into a gap between the annular wall of the key and the key wall, and the projection and the hole wall can be connected together in an embedded manner. The key is clamped in the key hole, and the projection and the lower part of the hole wall are connected together in the embedded manner. The combination irons out the defect that the original silica gel key of a conventional electronic product cannot be resistant to water in use. A provided silica gel key is good in performance of resistance to water, is simple and convenient in operation, and is wider in range of application. The improvement of the opening is that the periphery of the opening is provided with a circle of key grooves which cooperate with the key wall, so as to enable the waterproof effect to be good. A circle of annular wall is added inwards to the key wall, and the edge of the top of the annular wall is flanged outwards to form a circle of flange which clamps the bottom of the hole wall, thereby enabling the silica gel key to be fixed on the opening, and enabling the silica gel key not to loosen in use.

The further technical scheme of the utility model is, described projection is raised points, is distributed in the lower end of annulus wall.
The further technical scheme of the utility model is, described annulus wall is outside also has a circle button wall, between described annulus wall and button wall, has space.
Adopt as above the utility model of technical scheme, with respect to prior art, have following beneficial effect: overcome the original silica gel push-button of existing electronic product in use exist cannot waterproof defect, provide a kind of water resistance good silica gel push-button, easy and simple to handle, purposes is more extensive.
The purpose of this utility model is, compared with original silica gel push-button, to the utility model has the advantage of:
1, perforate is improved, open a circle by keyway in periphery, coordinate with button wall, waterproof effect is good.
2, button wall inwardly increases by a circle annulus wall, and annulus wall top is outwards dug the bottom that a circle flange blocks hole wall, silica gel push-button can be fixed in perforate, and button in use can not be come off.
Accompanying drawing explanation
In order to further illustrate the utility model, below in conjunction with accompanying drawing, further describe:
Fig. 1 is open-celled structure figure of the present utility model;
Fig. 2 is press-key structure figure of the present utility model;
Fig. 3 is assembling section of the present utility model;
Wherein: 1. perforate; 2. hole wall; 3. press keyway; 4. button; 5. button wall; 6. annulus wall; 7. projection; 8. button post.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
In conjunction with Fig. 2 and Fig. 3; A kind of full Waterproof push-button, comprises and presses wall, and pressing wall below has button post 8, it is characterized in that, comprises annulus wall 6, and described annulus wall 6 comprises projection 7 as fixing part.Therefore fix further increasing action power of part.Described button post 8 is positioned at the core of annulus wall 6.
Described protruding 7 is that a circle is dug, and is positioned at the lower end of annulus wall 6.Certainly, dig as preferred structure at this place, still, if described protruding 7 be raised points, is distributed in the lower end of annulus wall 6.Also can realize as above technical scheme; Certainly, projection can also be digging of the non-whole circle of part.Each the having by oneself of above structure can be realized technique effect.
Described annulus wall 6 is outside also has one to enclose button wall 5, between described annulus wall 6 and button wall 5, has space.Between described button post 8 and annulus wall 6, comprise space.Therefore clamping structure is closely knit, and inside does not have space.
In addition, the preferred silica gel material of the material at this place, but be not limited to silica gel material, can also be resilient other materials.
Scheme 2:
The key hole at this place and above-described button cooperating.
A kind of full Waterproof push-button hole, it is arranged on panel, it is characterized in that, comprises perforate 1, described perforate 1 has hole wall 2, described hole wall 2 can embed the space between annulus wall 6 and the button wall 5 of button around, and projection 7 can and hole wall 2 chimeric.
The inner supporting wall in addition of described hole wall 2, it can embed the space comprising between described button post 8 and annulus wall 6.
The cross section of described hole wall 2 is U-shaped.
Scheme 3:
A full Waterproof push-button combination, is characterized in that, button 4 comprises annulus wall 6, and described annulus wall 6 comprises projection 7 as fixing part; Key hole comprises perforate 1, and described perforate 1 has hole wall 2, described hole wall 2 can embed the space between annulus wall 6 and the button wall 5 of button around, and projection 7 can and hole wall 2 chimeric; Described button 4 snaps in key hole, and projection 7 and hole wall 2 belows are chimeric.
As shown in Figure 1-2, there is a perforate 1 on electronic product surface, at hole wall 2 place's opens outward one circles, presses keyway 3; Button wall 5 places of the button 4 of silica gel material are inwardly a circle annulus wall 6, and annulus wall 6 top are outwards dug a circle flange, and button is middle is button post 8.Button post 8 pushes up on the sensitive switch of shell interior circuit board, and button can be realized and drive the function of switch in 4 the top of pushing button.
As shown in Figure 3, button wall 5 is firmly compressed into perforate 1 outside by keyway 3, until the bottom that the flange on annulus wall 6 edges blocks hole wall 2 just.The diameter of silica gel push-button 4 is than perforate 1 slightly larger in diameter, and because silica gel material is soft, elasticity is very good, presses down with strength and can squeeze on hole wall 2, relies on frictional force can form certain fixing; Button wall 5 and annulus wall 6 are all squeezed in very closely by keyway 3 and hole wall 2, make water be difficult to enter the gap of hole wall 2 and button wall 5.
If hydraulic pressure is very large, when water enters the gap of hole wall 2 and button wall 5, water enters by keyway 3 along button wall 5, now, very large hydraulic pressure can push to such an extent that deformation quantity is larger by button wall 5, button wall 5 with by keyway 3, fit tightr, water can only be rested at most by keyway 3, can not cross by keyway 3 and enter in perforate 1.In certain range hydraulic pressure, hydraulic pressure is larger, button wall 5 with by keyway 3, fit tightr, water resistance is better.
The bottom that flange on annulus wall 6 edges blocks hole wall 2, can be fixed on button 4 in perforate 1 on the one hand, and button 4 in use can not be come off; Can again guarantee that on the other hand water can not enter perforate 1 inside.
more than show and described basic principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
