Abstract

The utility model relates to a keyboard, particularly relates to a keyboard which can drain water on self body, which has a main structure that an upper cover is provided with a groove, the front edge of the groove is provided with a plurality of drain holes and is downwards connected with drain pipe columns, and a bottom seat is provided with a plurality of sleeves which correspond to the drain pipe columns and the inner side of each of the sleeves forms a through hole. Therefore, water on the keyboard can be drained quickly to avoid short circuit of a circuit and prevent the circuit from being damaged.

Description

Waterproff keyboard

The utility model relates to a kind of keyboard, especially refers to discharge the keyboard of liquid on the keyboard (water).

At present, general traditional keyboard waterproof extreme difference, if there is liquid to flow into keyboard accidentally, touch circuit unit, then can cause short circuit, the damage of circuit, cause keyboard normally to use, as: national patent gazette Announcement Number the 194192nd, 254445, No. 279523 etc. the patent case has all disclosed keyboard structure; Another kind of known waterproff keyboard, as: national patent gazette is numbered those disclosed herein No. 236428, it mainly ties up to the loam cake bottom surface and covers down and is provided with most individual corresponding column pipes and perforation, and borrow column pipe moisture content to be imported in the liquid-collecting box of lower cover bottom surface setting, available to prevent that flow of liquid from going into circuit unit, this kind design structure is comparatively complicated, column pipe and perforation need be laid on the whole card, cause the inconvenience in the manufacturing, moreover, be when liquid is collected in keyboard, if stir keyboard because of carelessness, the liquid that then is stored in keyboard will upwards reflux, and causes severe impairment.

In view of this, the purpose of this utility model is a kind of waterproff keyboard, and it is a gradient of utilizing keyboard itself to have, can make the liquid that flows on it flow to the osculum of groove leading edge forward, and passes through directly downward the discharge in the keyboard outside of open-work of sleeve.

The purpose of this utility model is achieved in that a kind of waterproff keyboard comprises by loam cake, button, rubber body, circuit unit, base and touches pressure cap and form, it is characterized in that: be provided with groove last covering, this groove leading edge is offered a plurality of osculums, this osculum connects to the loam cake bottom, and also be connected with column pipe downwards, base is provided with a plurality of and the corresponding sleeve of column pipe, and this sleeve inner is formed with open-work, and column pipe stretches in the open-work of corresponding sleeve again.

Because adopt such scheme: the water on the keyboard can be discharged rapidly, avoid occurring short circuit, the damage of circuit, and structure is also simple.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments stereographic map.

Fig. 2 the utility model exemplary embodiments exploded view.

Fig. 3 the utility model exemplary embodiments cut-open view.

Among the figure: 10 loam cakes, 11 touch pressure cap, 16 grooves, 17 osculums, 18 column pipes, 19 sleeves, 20 open-works by strong, 12 rubber bodies, 13 circuit units, 14 bases, 15.

As Figure 1-3, present embodiment comprises that loam cake 10, button 11, rubber body 12, circuit unit 13 and base 14 etc. install locking in regular turn and form, wherein rubber body 12 is arranged between button 11 and the circuit unit 13, and shake-up pressure cap 15 tops of rubber body 12 contact with button 11.

When button 11 is depressed, button 11 is promptly depressed the shake-up pressure cap 15 of rubber body 12, make shake-up pressure cap 15 press circuit unit (film circuit board) 13 and make circuit turn-on, to form electric contact, loosen button 11, then utilize the elasticity of touching pressure cap 15, button 11 is replied original position, above-mentioned keyboard structure is a known techniques.

Loam cake 10 is provided with suitable groove 16, and offer a plurality of osculums 17 in groove 16 leading edges, because osculum 17 is to be positioned at groove 16 leading edge minimum point places, therefore, in the time of in liquid flows into groove 16, liquid can successfully enter osculum 17, this osculum 17 is to connect to loam cake 10 bottoms, and connect the column pipe 18 of a hollow form downwards, on the base 14 of keyboard, be provided with a plurality of column pipes 18 in addition and set the hollow form sleeve 19 of answering mutually, these sleeve 19 inner open-works 20 that form, column pipe 18 is to stretch in the open-work 20 of corresponding sleeve 19, borrows above-mentioned member to form a waterproff keyboard.

When liquid flows into keyboard, liquid can flow into groove 16 inside on the loam cake 10 and the gradient of utilizing keyboard itself to have, can make the liquid of inflow flow to the osculum 17 of groove 16 leading edges forward, and then the open-work 20 that sees through sleeve 19 is directly discharged in the keyboard outside downwards.

The waterproff keyboard of present embodiment can be discharged the liquid that flows into keyboard rapidly, can prevent effectively that liquid from flowing into circuit unit 13, with short circuit, the damage of avoiding causing circuit, moreover, the structure of osculum 17, column pipe 18 and sleeve 19, open-work 20 is very simple and only need be arranged on groove 16 leading edges, manufactures easily, has the effect that reduces cost and can directly liquid be discharged externally, need not carry out the operation of pouring liquid, also the danger of no liquid backflow.

Claims

1, a kind of waterproff keyboard comprises by loam cake, button, rubber body, circuit unit, base and touches pressure cap and form, it is characterized in that: be provided with groove last covering, this groove leading edge is offered a plurality of osculums, this osculum connects to the loam cake bottom, and also be connected with column pipe downwards, base is provided with a plurality of and the corresponding sleeve of column pipe, and this sleeve inner is formed with open-work, and column pipe stretches in the open-work of corresponding sleeve again.
