Abstract

The utility model relates to a waterproof and dustproof keyboard which comprises a key cap layer, a cover plate layer, a tray layer, a guide rod at the lower part of the key cap, a leading-out wire extending out of the tray layer, and a circuit board. The keyboard is characterized in that the key cap layer is connected with the cover plate layer in a sealing manner, and the key cap layer is also connected with the tray layer in a sealing manner. Because the keyboard adopts a fully closed structure, the keyboard has good waterproof performance and dustproof performance, and can be normally used under the severe circumstances, such as, in the rain and in the desert, and the service life is prolonged. The waterproof and dustproof keyboard of the utility model adopts rubber material to replace original spring and plastic, etc., and thereby the keyboard has the advantages that the keyboard is noise-free and has comfortable hand feeling and good shock resistance when in use. The problems of poor waterproof and dustproof performances, short service life, large noise and poor shock resistance of prior keyboard during the use can be solved for people.

Description

The water proof and dust proof keyboard

Technical field

The utility model relates to computer peripherals, particularly relates to a kind of water proof and dust proof keyboard.

Background technology

Computer keyboard is the recording device of computer, the frequency ratio of using is higher, there is following deficiency in common computer keyboard: the one, and water resistance is poor, being unsuitable for the abominable place of environment such as (warship, ship) waterborne, field, military affairs uses, the 2nd, anti-dust performance is poor, reduced the useful life of keyboard, the 3rd, noise is bigger, the vibrationproof poor performance.

The utility model content

For overcoming above-mentioned deficiency, the utility model discloses a kind of water proof and dust proof keyboard, can adapt to various environments for use, and be prolonged useful life.

A kind of water proof and dust proof keyboard comprises the guide rod of key cap layer, cover layer, pallet layer, keycap bottom, from lead-out wire and circuit board that pallet layer passes, it is characterized in that: between key cap layer and the cover layer, be tightly connected between key cap layer and the pallet layer.

Described guide rod is fixedlyed connected with keycap.

One elastic ring is arranged at described guide rod bottom, and described elastic ring is fixed on the circuit board.

The present invention is by being tightly connected the key cap layer of keyboard outside and cover layer and pallet layer, and lead-out wire and pallet layer are tightly connected, and make keyboard become full-closed structure, and this keyboard just can be applicable to various environment like this, has the function of water proof and dust proof.

Guide rod adopts with keycap fixedlys connected, and when knocking keyboard, both upper and lower motions simultaneously owing to there is not the slit between the two, produce noise so knock Shi Buhui.

Under the guide rod elastic ring is set, when the guide rod bottom was pressed on the circuit board, because the elastic force that elastic ring produces makes the vibrationproof performance of keyboard fine, and guide rod was depressed Shi Buhui generation noise.

The utlity model has the advantage of following several aspects: the one, excellent waterproofness, this keyboard structure is totally-enclosed design, keyboard is not made of salt, and places for a long time in the water, and do not influence keyboard and use, and can water flushing keyboard.The 2nd, the good dust-proof performance, this keyboard structure is totally-enclosed design, dust can not enter keyboard, is suitable for using in adverse circumstances such as desert.The 3rd, noiselessness, the keycap of this keyboard, key body adopt elastomeric material to make, and have replaced original spring, plastics etc., noiselessness when therefore operating, the 4th, good hand touch, the vibrationproof performance is strong, the keycap of this keyboard itself has certain elasticity, and operating handle is good, and the vibrationproof performance is strong.Five are to use conveniently, and the life-span is long.

Fig. 1 the utility model front view.

Fig. 2 the utility model A-A cutaway view.

Each label lists as follows among the figure:

The 1-keycap, 2-cover layer, 3-circuit board, 4-lead-out wire, 5-guide rod, 6-key cap layer, 7-pallet layer, 8-supporting layer, 9-elastic ring.

Fig. 1 is the utility model front view, and Fig. 2 is the utility model A-A cutaway view.A kind of water proof and dust proof keyboard, the guide rod 5 and the circuit board 3 that comprise key cap layer 6, cover layer 2, pallet layer 7, keycap 1 bottom, it is characterized in that: between key cap layer 6 and the cover layer 2, be tightly connected between key cap layer 6 and the pallet layer 7, be tightly connected between lead-out wire 4 and the pallet layer 7, make whole keyboard become full-closed structure, this keyboard just can be applicable to various environment like this, has the function of water proof and dust proof.

Guide rod 5 is fixedlyed connected with keycap 1, and when knocking keyboard, both upper and lower motions simultaneously owing to there is not the slit between the two, produce noise so knock Shi Buhui.When keyboard was not in user mode, the supporting layer 8 between pallet layer 7 and key cap layer 6 supported keycap 1 and guide rod 5, can not touch circuit board 3.One elastic ring 9 can be arranged at guide rod 5 bottoms, and elastic ring 9 is fixed on the circuit board 3.When the guide rod bottom was pressed on the circuit board, because the elastic force that elastic ring produces makes the vibrationproof performance of keyboard fine, and guide rod was depressed Shi Buhui generation noise.

Claims
