Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1-4, a kind of noiseless keycap, including keycap head 1, the upper surface of keycap head 1 is provided with non-slip mat, anti-skidding
Pad is fill-in pad containing vinyl acetate, and keycap head is fixedly connected with guide post 101 at the top of 1 inner cavity, because guide post 101 bottom with
The distance of 3 bottom of middle plate is more than the movable distance downwards of keycap head 1 so that guide post 101 will not be due to occurring to hit with middle plate 3
Sound is generated, the surface fixing sleeve of guide post 101 is connected to slip guiding sleeve 2, and slip guiding sleeve 2 is polyformaldehyde material connector sleeve, and polyformaldehyde material has resistance to
The excellent performance such as fatigue, creep resistance, wear-resisting, heat-resisting, impact resistance, and friction coefficient is small, self lubricity is good, and surface is smooth to be not easy
It generates friction and makes a sound, contacted with clamping block 401 during slip guiding sleeve 2 slides, the both sides of 2 lower surface of slip guiding sleeve are equal
It is fixedly connected with positive stop hook 201, slip guiding sleeve 2 extends to the inside of middle plate 3, and middle plate 3 includes casing 301, and the bottom end of casing 301 is set
It is equipped with storage block 302, the surface of storage block 302 is provided with set fishplate bar 303, and covers fishplate bar 303 and be square fixed plate, slip guiding sleeve
2 run through casing 301 and extend to the bottom of middle plate 3, and middle plate 3 is internally provided with movable block 4, and movable block 4 is flexible silicon blob of viscose,
Because movable block 4 is flexible silicon blob of viscose, slip guiding sleeve 2 can be moved in clamping block 401 into row buffering, to reduce because of slip guiding sleeve 2
The sound of activity and generation, movable block 4 include clamping block 401, and the inner wall of clamping block 401 is provided with flexible silicon rubber cushion 408, are limited
Hook 201 is located at the inside of flexible silicon rubber cushion 408, and the upper surface of clamping block 401 offers buckling groove 402,402 inner wall bottom of buckling groove
The both sides in portion offer blocked hole 403, and the opening of blocked hole 403 is adapted with the specification of positive stop hook 201, slip guiding sleeve 2
It being clamped by the blocked hole 403 inside positive stop hook 201 and clamping block 401, the bottom of clamping block 401 is fixedly connected with cylinder 404,
By changing the dependency structure of button, the meeting when structure for having sounding is changed to be inherently eliminated the percussion of keyboard
The possibility of sounding, to realize noiseless computer keyboard, to be suitble to need quietly various occasions uses, to improve keyboard
Practicability, the lower surface of clamping block 401 is fixedly connected with fixed block 405, and the lower surface of fixed block 405 is fixedly connected with lantern ring
406, the lower surface of lantern ring 406 is fixedly connected with foundation 407, and the quantity of foundation 407 is eight, and each two foundation 407 is one
Group, four groups of foundation 407 are with the formal distribution of annular array in the lower surface of lantern ring 406.
The electric elements occurred in this article are electrically connected with extraneous main controller and 220V alternating currents, and main controller can be meter
Calculation machine etc. plays the conventionally known equipment of control.
When in use, keycap head 1 is tapped, keycap head 1 moves downward together with slip guiding sleeve 2, will push down on movable block 4
In downward projection of cylinder 404, signal will be formed when 404 bottom of cylinder is pressed onto computer keyboard conductive switch to reality
Existing keyboard entry function, when computer input action is completed, that is, finger leaves keycap head 1, slip guiding sleeve 2 and keycap head 1
Under the elastic force effect of movable block 4, move upwards to restore to the original state, the positive stop hook 201 of slip guiding sleeve 2 can hook blocked hole 403
Opening to stop motion.
In conclusion the noiseless keycap, by the way that slip guiding sleeve 2, positive stop hook 201 and buckling groove 402, the limit of slip guiding sleeve 2 is arranged
Position hook 201 is surrounded by flexible silica gel, positive stop hook 201 and middle plate 3 will not direct collision, disappeared by the buffering of elastic silica gel
Except making a sound, ebonite hits the possibility of sounding with ebonite when percussion to be inherently eliminated keyboard, to be suitble to need to pacify
Quiet various occasions use, to improve the practicability of keyboard.
