Embodiment

Technological means and the effect thereof taked for further setting forth the utility model are described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.

See also Fig. 2, the utility model provides a kind of keyboard, comprise: deckle board (not shown), be installed on spring support (not shown) on deckle board, be installed on scissor (not shown) on deckle board, be installed on the keycap 2 on deckle board and be installed on first, second and the

3rd balance strip

4,6,8 on keycap 2, described keycap 2 by first, second and the

3rd balance strip

4,6,8 and scissor be installed on deckle board, wherein, deckle board, spring support and scissor all can be selected existing structure, and therefore not to repeat here.

Described keycap 2 comprises panel 22 and is connected in the side plate 24 of panel 22, and described first, second and the

3rd balance strip

4,6,8 are installed on described panel 22, and arrange near described side plate 24, so that counter plate evenly supports, and then strengthen pressing touch.

Described the first balance strip 4 comprises the first noumenon 42, be vertically connected at first arm 44 at the first noumenon 42 two ends and be vertically connected at free-ended the first extension 46 of the first arm 44; Described the second balance strip 6 comprises the second body 62, be vertically connected at second arm 64 at the second body 62 two ends and be vertically connected at free-ended the second extension 66 of the second arm 64; Described the 3rd balance strip 8 comprises the 3rd body 82, be vertically connected at the 3rd arm 84 at the 3rd body 82 two ends and be vertically connected at free-ended the 3rd extension 86 of the 3rd arm 84.

Described first, second has different length from the

3rd body

42,62,82.In the present embodiment, the length of described the first noumenon 42 is greater than the length of the second body 62; The length of described the second body 62 is greater than the length of the 3rd body 82.

22 pairs of described panels should first, second and the

3rd body

42,62,82 be provided with several first, second and the 3rd pivot connected slot 224,226,228, described first, second and the

3rd body

42,62,82 be articulated in respectively this first, second and the 3rd pivot connected slot 224,226,228 in.wherein, described first, second and the 3rd pivot connected slot 224,226,228 number can adjust accordingly according to first, second and the

3rd body

42,62,82 length, described first, the second and the

3rd extension

46, 66, 86 are connected on deckle board, and then keycap 2 is installed on deckle board, when keycap 2 is subject to pressure towards the spring support direction, keycap 2 moves towards spring support, the extruding spring support, spring support applies reaction force to keycap 2, when the active force towards spring support that keycap 2 is applied is cancelled, the reaction force that spring support applies keycap 2 makes keycap 2 move away from spring support, in this process, described first, the second and the

3rd balance strip

4, 6, 8 first, the second and the 3rd pivot connected

slot

224, 226, 228 rotations, make this keycap 2 uniform stresseds, strengthened the operating handle of button, and because three balance strips are simultaneously stressed, compare with existing wall scroll balance strip structure, the stressed less of balance strip of the present utility model, not fragile, extended the useful life of button.
