Abstract

The utility model discloses a cap of a key, which comprises a cover body and a rectangular splicing column positioned below the cover body. The utility model is characterized in that both sides of the rectangular splicing column are provided with long and thin guide strips which are extended longitudinally at four corners of the rectangular splicing column; both sides of the rectangular splicing column are symmetrically provided with elastic clamping hooks, and both sides of each clamping hook are provided with gaps. Compared with a cap of a traditional computer key, the utility model has the advantages of small upper and lower moving friction, smooth knocking, small swinging amplitude, low noise, etc., and is not easy to appear key clamping phenomenon.

Description

A kind of button keycap

Technical field

The utility model relates to the button keycap on a kind of computer keyboard.

Background technology

Existing various keyboard is mostly by keycap, the keycap guide groove, the key panel, caoutchouc elasticity touches body and the contact wiring board is formed, the rectangle inserting column that keycap extends by its below is installed in the rectangle keycap guide groove, down on time, the convex shake-up body that caoutchouc elasticity touches body contacts soft silver point circuit board, upper contact passes thermal insulation board circular hole contact contact turning circuit down, these keyboards all have general defective, that be exactly in use keycap very easily rock, the frictional force that keycap is subjected in the process of moving up and down is bigger, make and to knock smooth and easy inadequately comfortablely, be easy to generate noise and card key phenomenon.

The utility model content

At the deficiencies in the prior art, the purpose of this utility model be to provide a kind of knock smooth and easy comfortable, rock little, noise is low, card key rate low button keycap.

For achieving the above object, the utility model button keycap comprises lid and is positioned at the rectangle inserting column of lid below, the both sides at four jiaos of places of inserting column are provided with the elongated sliver of longitudinal extension, are provided with elastic fastening hook to the inserting column bilateral symmetry, and the grab both sides are provided with the space.

Further, the cross section of described sliver is the semi-circular projection shape.

Further, the cheicers place of described grab is provided with the noise reduction inclined-plane.

Further, each crest line place of described top surface all leads fillet.

Further, be provided with the card structure that is used for clamping button balancing pole below the described lid.

Further, described grab is a pair of, along the close respectively lid two side of balancing pole direction.

Further, be provided with guide cylinder below the described lid.

Inserting column of the present utility model four Jiao Chu both sides are provided with the elongated sliver of longitudinal extension, can be slidingly matched with the smooth inner wall of guide groove, owing to be line face contact movement, therefore contact-making surface is few, reduced the mobile frictional force of guiding up and down, make knock more smooth and easy and shaking amplitude little, noise is low, the power that hooks together of grab and keycap guide groove can be effectively controlled in the space of grab both sides, keycap can or not knocked energetically because of vibrations to come off, during the keycap bounce-back, the inclined-plane at card structure cheicers place is done oblique point with the bending inwall of keycap guide groove and is contacted, be difficult for rocking and producing noise, and below long lid, balancing pole card structure be set, then guaranteed to knock any place of key cap surface and card key phenomenon all can not occur interfering.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1 to Figure 3, lid 1 roughly is square cap-like structure, it is slightly inwardly recessed that it knocks face, each crest line place, surface all leads fillet, the smooth smoothness of lines, and has certain gradient, meet ergonomics, the inserting column 2 that extend lid 1 below is rectangle, and is hollow-core construction, inside is provided with ribs, the both sides at four jiaos of places of inserting column 2 are provided with the elongated sliver 3 of longitudinal extension, and the cross section of sliver 3 is semicircle shape, and inserting column 2 both sides also are provided with elastic fastening hook 4 symmetrically, grab 4 both sides are provided with space 5, and the cheicers place of grab 4 is provided with noise reduction inclined-plane 6.

Keycap majority on the computer keyboard be the square, all the other some strips as: ENTER, SHIFT, space bar are commonly called the multiple key, and traditional multiple key all is provided with balancing pole, to avoid occurring tilt phenomenon when knocking the non-middle position of keycap.

As Fig. 4, Fig. 5, enter key shown in Figure 6, in order to guarantee the stationarity of keycap in the process of pressing down, lid 11 belows are except being provided with inserting column 12, also be provided with the card structure 13 and the guide cylinder 14 that are used for clamping button balancing pole, grab is a pair of, the position is corresponding with balancing pole, and along the balancing pole direction respectively near the two side of lid 11.

SHIFT key as shown in Figure 7, inserting column 22 is positioned at the middle position of lid 21, and card structure 23 roughly is positioned at the Liang Jiaochu of lid 21.

Space bar as shown in Figure 8, inserting column 32 is positioned at the middle position of lid 31, and its both sides are provided with 34, two pairs of two guide cylinder card structure 35 and are arranged on the sidewall, and respectively near the two ends of lid 31.

The utility model is not limited to above-mentioned preferred forms; anyly go under enlightenment of the present invention, all can draw other various forms of products; though but on its shape or structure, do any variation, the keycap that vertical sliver and elastic fastening hook are set on every inserting column all drops within the protection range of the present utility model.
