The utility model discloses a reach above-mentioned purpose through following technological means:

a mute keyboard key comprises a base, an upper cover, a key, a spring, a movable reed and a static reed, wherein the upper cover is buckled and connected with the base, a containing cavity is formed between the upper cover and the base, the key, the spring, the movable reed and the static reed are all arranged in the containing cavity, a second positioning column extends downwards from the key and is correspondingly arranged in a guide hole of a first positioning column on the base, and the second positioning column is embedded in the guide hole and can move up and down along the guide hole; the spring is arranged between the key and the base, one end of the spring is sleeved with the second positioning column, and the other end of the spring is sleeved with the first positioning column;

a mute gasket is sleeved outside the second positioning column between the spring and the key, two extending parts are symmetrically arranged on two sides of the static gasket, and the two extending parts are respectively penetrated in the corresponding movable holes on the key and can move up and down in the movable holes; the key is provided with two sliding rails which are oppositely arranged by taking the first positioning column as a central axis, the two sliding rails are in sliding fit with a sliding groove arranged on the base, and the lower ends of the sliding rails are propped against a silencing pad on the base; the apex angle arris of the free end of extension upwards forms arc bellying to one side, the arc bellying with the caping inner wall counterbalance of upper cover just moves contact with the top of slide rail.

As a further aspect of the present invention, one side of the mute gasket is provided with a cylindrical protrusion, which is embedded in the through hole on the key sidewall.

Compared with the prior art, the beneficial effects of the utility model are that:

due to the adoption of the structural design, the mute gasket is sleeved outside the second positioning column of the key, the arc-shaped convex part of the extending part of the mute gasket is contacted with the top end of the sliding rail when the key of the mute keyboard is in a working state, and the arc-shaped convex part of the extending part of the mute gasket is contacted with the inner wall of the cover top of the upper cover when the key is in a static state, so that the key is prevented from directly touching the upper cover and the base when the working state and the static state are switched, and the mute is realized.

The reference numbers in the figures are respectively: (1) the device comprises a base, an upper cover (2), a key (3), a spring (4), a movable spring sheet (5), a static spring sheet (6), a second positioning column (7), a first positioning column (8), a guide hole (9), a silent gasket (10), an extending part (11), a movable hole (12), a sliding rail (13), a sliding groove (14), a silencing pad (15), an arc-shaped protruding part (16), a cylindrical protrusion (17) and a through hole (18).

Detailed Description

The invention will be described in further detail with reference to the accompanying drawings:

referring to fig. 1 and 2, the mute keyboard key of the present invention includes a base 1, an upper cover 2, a key 3, a spring 4, a movable reed 5 and a stationary reed 6, wherein the upper cover 2 is connected with the base 1 in a buckling manner, the upper cover 2 and the base 1 form an accommodating cavity, the key 3, the spring 3, the movable reed 4 and the stationary reed 5 are all installed in the accommodating cavity, and a cross key portion of the key passes through the top of the upper cover; the static spring and the movable spring are arranged on the base, the static spring is positioned beside the movable spring, and welding pins of the static spring and the movable spring extend out of the base; the key 3 extends downwards to form a second positioning column 7 which is correspondingly arranged in a guide hole 9 of a first positioning column 8 on the base 1, and the second positioning column 7 is embedded in the guide hole 9 and can move up and down along the guide hole 9; the spring 4 is arranged between the key 3 and the base 1, one end of the spring 4 is sleeved with the second positioning column 7, and the other end of the spring 4 is sleeved with the first positioning column 8;

a mute gasket 10 is sleeved outside the second positioning column 7 between the spring 4 and the key 5, two extending parts 11 are symmetrically arranged on two sides of the static gasket 10, and the two extending parts 11 are respectively penetrated in the corresponding movable holes 12 on the key 3 and can move up and down in the movable holes 12; the key 3 is provided with two sliding rails 13 which are oppositely arranged by taking the first positioning column 8 as a central axis, the two sliding rails 13 are in sliding fit with a sliding groove 14 arranged on the base, and the lower ends of the sliding rails 13 are propped against a silencing pad 15 on the base; the vertex angle arris of the free end of the extension part 11 forms an arc-shaped bulge part 16 obliquely upwards, and the arc-shaped bulge part 16 is propped against the inner wall of the cover top of the upper cover 2 and is in movable contact with the top end of the slide rail.
