The invention has the beneficial effects that: the input key has good waterproof sealing performance when not in use, can effectively reduce the pressure when in pressing, and prolongs the service life of the key.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a top view of the present invention.
Detailed Description
As shown in figures 1 and 2, the input key comprises a key body 8 embedded in a key slot 11, the key slot 11 is arranged on a keyboard surface 12 of equipment, the key body 8 is partially buckled in the key slot 11 and partially extends out of the upper end surface of the keyboard surface 12 of the equipment, a cavity 1 with an opening on the upper end surface is arranged inside the key body 8, a clamping slot is respectively arranged at the edge of the key body, a pressing plate 4 is movably arranged in the clamping slot, a pressing part is formed by splicing a plurality of pressing plates 4, a clearance cavity 5 is formed between the pressing plates, a sealing part 2 is formed outside the pressing plate 4, the sealing part 2 extends towards the outside of the key body 8, the bottom of the sealing part 2 is in contact sealing with the upper end surface of the keyboard surface, a plurality of sealing parts 2 seal each clearance surface of the key body, an elastic part 7 is arranged in the cavity 1, the elastic part 7 jacks each pressing plate 4, so that one side top of each pressing plate 4 is inclined upward.
In this embodiment, a rectangular notch is formed at the center of each pressing plate 4, the elastic member 7 is positioned and installed in the rectangular notch, the elastic member 7 adopts an elastic air bag ball with resilience capability, a spherical cavity is arranged in the elastic air bag ball, air inlet and outlet holes are formed in the outer wall of the air bag ball, the elastic member is arranged, so that each pressing plate has the function of resilience homing after being pressed down, the purpose of buffering is achieved in the pressing process, the problem of reduction of the service life caused by overlarge pressing force is solved, meanwhile, when the pressing plate is pressed down, the peripheral dust can be blown away by using the gas inside, and the purpose of removing the dust is achieved.
Wherein, the inner wall both sides of draw-in groove are provided with a pivot hole respectively (not shown), and the both sides of pressing the clamp plate 4 are provided with corresponding pivot just facing the pivot hole, and the pivot rotates and sets up in the pivot is downthehole, and the rotation can be realized through the pivot of both sides to the pressing the clamp plate.
