Conventional computor-keyboard pushbotton is " work " character form structure or " X " shape structure at present, the button that is no matter " work " character form structure or " X " shape structure includes key cap cover, key cap base, key cap cover inner side is provided with contact block, through hole is set in key cap base, contact block can pass through hole, make contact block can touch the printed circuit on keyboard, thereby realize input.The button of this class " work " character form structure or " X " shape structure, no matter key cap cover is under pressed state or nature, all have gap with key cap base, use for a long time, dust can enter in these gaps, accumulate over a long period, these dusts can enter on printed circuit board, pollute printed circuit board, can cause button malfunction, affect user and use, reduce the useful life of keyboard.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, provides a kind of simple in structure, can place the keyboard between dust enter key cap and key cap base, to guarantee the useful life of keyboard.
For achieving the above object, the technical solution used in the present invention is: a kind of dustproof computor-keyboard pushbotton, comprise the key cap cover with contact block and the key cap base with through hole that supports described key cap cover, described contact block can pass described through hole, it is characterized in that: described key cap cover periphery of its sidewall and described key cap base under pressed state not fits tightly, described key cap cover can be coated described key cap base under pressed state, is also provided with the return unit that key cap cover and contact block are resetted between described key cap cover and described key cap base.
In a preferred embodiment of the present invention, further comprise that described key cap base periphery is provided with a circle groove, described key cap cover madial wall be provided with a circle can snap in skid off the boss of described groove.
In a preferred embodiment of the present invention, further comprise that described return unit is back-moving spring, is all connected with described back-moving spring in described contact block both sides between described key cap cover and described key cap base.
In a preferred embodiment of the present invention, further comprise that described groove and boss are respectively mutual recessed circle and the convexity mating, the longitudinal length of described groove and boss is all less than or equal to the deformation quantity in described back-moving spring maximum compression situation.
In a preferred embodiment of the present invention, further comprise that the length that described contact block stretches out described through hole is less than or equal to the deformation quantity in described back-moving spring maximum compression situation.
In a preferred embodiment of the present invention, further comprise that described boss is one-body molded on described key cap cover madial wall by having flexible rubber.
The invention solves the defect existing in background technology, dustproof computor-keyboard pushbotton of the present invention is by fitting tightly key cap cover periphery of its sidewall and key cap base under pressed state not, make key cap cover can be coated key cap base under pressed state, guarantee between key cap cover and key cap base to be sealing state, stop dust to enter, realize dust reduction capability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
In figure: 10, key cap cover, 11, contact block, 12, boss, 20, key cap base, 21, through hole, 22, groove, 30, back-moving spring.
Embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, the invention provides a kind of dustproof computor-keyboard pushbotton, comprise that inner side is provided with the key cap base with through hole 21 20 of key cap cover 10 and the support key cap cover 10 of contact block 11, contact block 11 can pass through hole 21, make contact block 11 can touch the printed circuit on keyboard, thereby realize input, key cap cover 10 in the present invention periphery of its sidewall and key cap base 20 under pressed state not fits tightly, key cap cover 10 can be coated key cap base 20 under pressed state, and between key cap cover 10 and key cap base 20, be also provided with the return unit that key cap cover 10 and contact block 11 are resetted.
Concrete, at key cap base 20 peripheries, one circle groove 22 is set, key cap cover 10 madial walls arrange a circle can snap in skid off the boss 12 of groove 22, during use, when key cap cover 10 is not pressed, boss 12 on key cap cover 10 madial walls is stuck in the groove 22 of key cap base 20 peripheries, makes to form an annular seal space between key cap cover 10 and key cap base 20, has stoped entering of dust; When key cap cover 10 pressurizeds depress, boss 12 on key cap cover 10 madial walls skids off groove 22, boss 12 skids off after groove 22, arrive on key cap base 20 bottom margins, and key cap base 20 bottom margins are resisted against on boss 12, the coated key cap base 20 of boss 12, dust also cannot enter key cap 10 and key cap base 20 between, realize dustproof effect; When key cap cover 10, to have depressed input released, and return unit rises key cap cover 10 and contact block 11, and boss 12 snaps in groove 22 under the effect of return unit, therefore, button is from being input to reseting procedure, and the space between key cap cover 10 and key cap base 20 is sealing state, and dust cannot enter, realized dustproof function, meanwhile, so sealing state, also can reach the effect of waterproof, fail safe is improved, and has guaranteed to have the useful life of the keyboard of this button.
In the present invention, return unit is back-moving spring 30, between key cap cover 10 and key cap base 20, in contact block 11 both sides, is all connected with this back-moving spring 30, by back-moving spring 30, can prevent the situation of card key.
Further; groove 22 is respectively mutual recessed circle and the convexity mating with boss 12; groove 22 is all less than or equal to the deformation quantity in back-moving spring 30 maximum compression situations with the longitudinal length of boss 12; groove 22 can be along the edge setting of key cap base 20 bottoms; so, when key cap cover 10 depress and the process that resets in, all can not be separated from key cap base; remain fit-state, guarantee dust can enter key cap 10 and key cap base 20 between.
Further, the length that contact block 11 stretches out through hole 21 is less than or equal to the deformation quantity in back-moving spring 30 maximum compression situations, to guarantee that contact block 11 is when resetting, contact block 11 can with keyboard on printed circuit board depart from, complete input.
Boss 12 in the present invention is one-body molded on key cap cover 10 madial walls by having flexible rubber, makes boss 12 have elasticity, be more conducive to boss 12 snap in swimmingly skid off groove 22.
In sum, dustproof computor-keyboard pushbotton of the present invention is by fitting tightly key cap cover periphery of its sidewall and key cap base under pressed state not, make key cap cover can be coated key cap base under pressed state, guarantee between key cap cover and key cap base to be sealing state, stop dust to enter, realize dust reduction capability.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine technical scope according to claim scope.
