Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 5, a keycap capable of changing characters and being conveniently recognized includes a housing 1, a cover plate 2 detachably connected to the top of the housing 1, and characters 3 and braille bump characters 4 corresponding to the characters 3 arranged on the upper surface of the cover plate 2;

the both sides at apron 2 all are equipped with draw runner 5, the both sides at 1 top of casing are equipped with the spout 16 that is used for with 5 sliding connection of draw runner, the one end of spout 16 is equipped with the locating piece 6 that is used for with 5 butts of draw runner, the other end of spout 16 is equipped with supplies 5 male openings of draw runner, each draw runner 5 all is equipped with fixture block 7, fixture block 7 is equipped with spring 8, spring 8's one end is connected with fixture block 7, spring 8's the other end is connected with draw runner 5, draw runner 5 is equipped with the through-hole 9 that is used for holding establishing spring 8 and fixture block 7, spout 16 is equipped with the card hole 10 that is used for with 7.

The utility model discloses can realize changing the character 3 on the key cap, conveniently as reserve key cap, change the character 3 on the key cap through changing the apron 2, realize carrying out corresponding single change to invalid or damaged key cap, need not to change whole keyboard, reduce cost; through setting up the braille bump character 4 corresponding with character 3, make things convenient for the blind person to use, strengthen practicality and the nimble degree of use.

Specifically, when the characters 3 need to be replaced, the clamping blocks 7 on the two sides of the cover plate 2 on the shell 1 are pressed into the through holes 9, and then the cover plate 2 slides out of the sliding grooves 16 through the sliding strips 5, so that the cover plate 2 is detached; then, the slide bar 5 of another cover plate 2 to be replaced slides in from the sliding groove 16, and then the clamping block 7 of the slide bar is pressed into the through hole 9, at the moment, the spring 8 is stressed and compressed, so that the slide bar 5 completely slides into the sliding groove 16, and when the cover plate 2 slides to the through hole 9 and is aligned with the clamping hole 10, the clamping block 7 pops out the through hole 9 to be clamped with the clamping hole 10 under the elastic force action of the spring 8, so that the cover plate 2 is fixed. In addition, the positioning block 6 is used for avoiding the slide strip 5 from sliding out due to excessive sliding.

In this embodiment, the surface of the case 1 is provided with an electroplated layer. The arrangement has the advantages that the surface of the shell 1 is protected, scratches can be generated on the surface of the shell 1 conveniently, and the attractiveness is improved.
