Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

As shown in fig. 1-3, the dustproof keycap of the embodiment includes a flexible dustproof ring 2, a cap body 1, and a connection column 3 for connecting the cap body 1 and the key switch 5, the flexible dustproof ring 2 includes a longitudinal portion 21 and a transverse portion 22 connected to each other, the longitudinal portion 21 and the transverse portion 22 form an L-shaped structure, the longitudinal portion 21 is connected to an inner wall of the bottom of the cap body 1, and the transverse portion 22 abuts against the bottom of the keyboard hole 4.

Specifically, by arranging the soft dust ring 2 between the cap body 1 and the keyboard hole 4, dust or snack residues can be effectively prevented from entering the keyboard hole 4, and the soft dust ring 2 with the structure of the shape like the Chinese character 'L' is prevented from being clamped, so that the cap body 1 and the keyboard hole 4 can be better attached.

In addition, because the soft dust ring 2 is soft, when the cap body 1 needs to be independently taken out of the keyboard hole 4, the soft dust ring 2 does not prevent the cap body 1 from being independently taken out of the keyboard hole 4; after the cap body 1 is taken out, if the cap body 1 is to be installed in the keyboard hole 4, the soft dust ring 2 is only required to be plugged into the keyboard hole 4 by using tools such as tweezers.

As shown in fig. 1-3, in the dustproof keycap of the present embodiment, the soft dustproof ring 2 is made of soft rubber. The soft glue has low production cost and good flexibility, and is suitable for mass production.

As shown in fig. 1-3, in the dustproof key cap of the present embodiment, the lateral portion 22 of the flexible dustproof ring 2 is formed by a plurality of bristles. Specifically, the plurality of bristles are arranged relatively densely, ensuring that as much as possible of dust or snack residues are prevented from entering the keypad holes 4, preventing a click.

As shown in fig. 1-3, in the dustproof keycap of the present embodiment, the cap body 1 includes a cover body 11 with a top surface printed with identification characters, and a transparent top cover 12 covering the outside of the cover body 11; the longitudinal part 21 of the flexible dustproof ring 2 is connected with the inner wall of the bottom of the transparent top cover 12; the connecting column 3 is arranged at the bottom of the cover body 11.

The transparent top cover 12 ensures that the identification characters on the cover 11 can be recognized by the user. Through set up transparent top cap 12 outside lid 11, can prevent effectively that in long-term the use, the sign character on the lid 11 from being worn and torn or is worn away, avoids influencing the normal use of keyboard.

As shown in fig. 1-3, in the dustproof keycap of the embodiment, two sides of the cover 11 are both provided with a clamping groove 13; a trapezoidal clamping block 14 which is used for being clamped with the clamping groove 13 is arranged on the inner wall of the transparent top cover 12; the width of the lower edge of the trapezoid clamping block 14 is smaller than the inner diameter value of the clamping groove 13; the width of the upper edge of the trapezoid clamping block 14 is larger than the inner diameter value of the clamping groove 13.

When installing transparent top cap 12 on lid 11, only need aim at the position of draw-in groove 13 with trapezoidal fixture block 14, slowly push transparent top cap 12, because the width on the lower limit of trapezoidal fixture block 14 is less than the internal diameter value of draw-in groove 13 just the width on the upper limit of trapezoidal fixture block 14 is greater than the internal diameter value of draw-in groove 13, consequently along with the process of slowly pushing transparent top cap 12, trapezoidal fixture block 14 finally can with draw-in groove 13 joint, accomplish the installation. Similarly, when the transparent top cover 12 needs to be detached from the cover 11, the transparent top cover only needs to be pulled out from the cover 11 with force.

As shown in fig. 1-3, in the dustproof keycap of the embodiment, the top of the cap body 1 is an arc concave surface.

Through setting up the front end that the arc concave surface can laminate the hand, the discernment of being convenient for points and fixes a position fast, when knocking the keyboard, can accurately press in the position at the center of key cap, avoids invalid keyboard that strikes.

As shown in fig. 1-3, in the dustproof keycap of the present embodiment, the top of the cap body 1 is provided with a frosted anti-slip pattern (not shown in the figures).

The friction between the fingers and the cap body 1 can be increased, and slipping is prevented.

As shown in fig. 1-3, in the dustproof keycap of the embodiment, a metal ring 15 is further disposed on the inner wall of the cap body 1.

By arranging the metal ring 15, the gravity center of the cap body 1 can be placed at the edge of the cap body 1, and invalid knocking of a keyboard is avoided.

The above is only a preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the protection scope of the present invention.
