Abstract
The utility model relates to an improved keyboard rubber push-button comprising a push-button body, a positioning sleeve, connecting pieces, and elastic bodies; the connecting piece is sheathed in the positioning sleeve and is embedded into the cross slot of the push-button body by means of the cross rib of the connecting piece to make the side piece of the connecting piece and the inclined convex piece of the connecting piece position on the chute of the positioning sleeve; the push-button body moves in the chute by means of the side piece and the inclined convex piece of the of the connecting piece during push. The inside of the elastic body positioned on the lower side of the convex circle is provided with multiple convex ribs, and a bottom is divided into multiple arc convex surfaces by making use of a groove. The convex surface is provided with a convex point, and the convex point is used for reducing the contact surfaces of the elastic body and a PC plate. A cutting groove can make the elastic body smoothly remove air inside the elastic body under pressing; thus the push-button keeps silent during push.
Description
The utility model relates to a kind of keyboard rubber key of improvement, be meant especially that a kind of assembling is convenient, push steadily, and balance is got rid of the interior air of elastomer to reach balance and noise reduction purpose and can increase the keyboard rubber key of the improvement of elastomeric elastic restoring force in good time.
The keyboard of prior art is assembled inconvenience because of complex structure mostly, and is difficult to keep good balance and sends tangible keystroke sound when pushing.
The purpose of this utility model is to overcome the defective of prior art and keyboard rubber key that a kind of improvement is provided.
For realizing the keyboard rubber key of a kind of improvement that the purpose of this utility model proposes, it includes positioning sleeve, connector, keying body and elastomer; The central authorities of described positioning sleeve are provided with stepped through hole, and two sides in hole are provided with relative chute, and chute is formed by connecting by inside and outside planomural a, b and a skew wall c; Central authorities' one end of described connector is provided with the cross rib, and the other end is provided with dome, and cross rib two sides are provided with lateral plate, and an oblique lug is extended in the lateral plate below; The bottom inside of described keying body is provided with cross recess; Utilize a plurality of short slots to form a plurality of convex surfaces on the described elastomeric bottom, convex surface is provided with salient point, and bottom inside is provided with a plurality of fins; The lateral plate of described connector is inserted along the chute of positioning sleeve, make on the lateral plate of described fitting and the interior planomural a and skew wall c that oblique lug lays respectively at described chute, so that convexedly stretch in the interior location of cross recess that the outer connector cross rib of described positioning sleeve can directly embed described keying body, and make described be positioned cover can be between described keying body and described connector activity, the dome face of described connector just contacts at described elastomeric end face.
Above-mentioned elastomeric inside can be provided with a plurality of fins to increase elastomeric intensity, discharges smoothly when above-mentioned short slot should be able to make the air in the described elastomer be squeezed.
This shows, the utlity model has simple in structure, assembling rapidly, low, the movable steady and noiseless advantage of button of cost.
Below in conjunction with accompanying drawing structure of the present utility model and function thereof are elaborated, wherein:
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is a constitutional diagram of the present utility model.
Fig. 3 is an assembled sectional view of the present utility model.
Fig. 4 is an assembled sectional view of the present utility model.
Structure of the present utility model includes positioning sleeve 1, connector 2, keying body 3 and elastomer 4; The central authorities of positioning sleeve 1 are provided with stepped through hole 11, and two sides in hole 11 are provided with relative chute 12, and chute 12 is formed by connecting by inside and outside planomural a, b and a skew wall c; Central authorities' one end of connector 2 is provided with cross rib 21, and the other end is provided with dome 22, and cross rib 21 2 sides are provided with lateral plate 23, and an oblique lug 24 is extended in lateral plate 23 belows; The bottom inside of keying body 3 is provided with cross recess 31; Utilize a plurality of short slots 41 to form a plurality of convex surfaces 42 on the bottom of elastomer 4, convex surface 42 is provided with salient point 43, and bottom inside is provided with a plurality of fins 44;
During assembling, the lateral plate 23 of connector 2 is inserted along the chute 12 of positioning sleeve 1, make on the lateral plate 23 of connector 2 and the interior planomural a and skew wall c that oblique lug 24 lays respectively at chute 12, so that convexedly stretch in the cross recess 31 interior location that the cross rib 21 of the connector 2 outside the positioning sleeve 1 can directly embed keying body 3, and making positioning sleeve 1 can be between keying body 3 and connector 2 movable, the face of the dome 22 of connector 2 then just contacts at the end face of elastomer 4.Like this, just form the keyboard rubber key of a modular improvement.
The utility model keying body 3 can be done upper and lower displacement along the chute 12 of positioning sleeve 1 by the lateral plate 23 of connector 2 two sides and oblique lug 24 when pushing, make the displacement of keying body 3 steadily sliding along and do not have a possibility of deflection.
It is splendid that rubber key of the present utility model can be pushed 5,000 ten thousand practicality at least.
