Abstract
The utility model discloses a whole-closed computer keyboard, which is composed of a key cap layer, a cover plate layer and a pallet layer. The utility model adopts the whole-closed design, and has favorable waterproof and dustproof performance. The whole-closed computer keyboard is suitable for being used in harsh environments, such as on water (ships, boats), fields, military affairs, etc. The whole-closed computer keyboard has the advantages of low noise, good hand feeling, convenient use and long lifetime when operated. The distribution of keyboard caps adopts the distributed standard of world universal key surfaces; an internal circuit board and each item of relevant indexes all adopt national standard.
Description
The utility model relates to a kind of computer keyboard, specifically totally-enclosed computer keyboard.
Computer keyboard is the recording device of computing machine, and the frequency ratio of use is higher.There is following deficiency in common computer keyboard: the one, and water resistance is poor, be unsuitable for the abominable place use of environment such as (warship, ship), field, military affairs on the water, the 2nd, anti-dust performance is poor, has reduced the serviceable life of keyboard, the 3rd, noise is bigger, the vibrationproof poor performance.
For overcoming above-mentioned deficiency, the utility model discloses a kind of totally-enclosed computer keyboard.
The utility model is achieved through the following technical solutions.
A kind of totally-enclosed computer keyboard is made up of strong cap layer, cover layer and pallet layer, and cover layer, pallet layer and key cap layer are tightly connected, and are provided with supporting layer in key cap layer and the pallet layer, and keycap and guide rod fuse, and the bottom of guide rod is an elastic ring.Big keys such as space bar, enter key, tab key, cap lock key, shift key, lining one deck duroplasts in keycap.The top of streamlined keyboard is provided with a groove.
During assembling circuit board is placed between pallet layer and the supporting layer, trip bolt adds the sealing rubber washer, drips seccotine between the slit of extension line, with the totally-enclosed the utility model of promptly making of keyboard.
The utlity model has the advantage of following several respects: 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 rugged surroundings 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, and 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.
