Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-3, a key switch includes a switch base 10 and a panel 20 connected to the switch base 10, wherein a button plate groove 101 is formed in the switch base 10, a button plate 30 is disposed in the button plate groove 101, a switch button linked with the button plate 30 is disposed in the switch base 10, the button plate 30 tends to bounce upward, the button plate 30 is limited in the button plate groove 101 by a limit mechanism, more than 2 guide posts 302 are formed at the lower end of the button plate 30, and a guide hole 103 matched with the guide posts 302 is formed in the button plate groove 101. Specifically, the utility model discloses key switch is through pressing the board 30 on the panel 20, by pressing the switch button in the board 30 drive switch seat 10, the switch of control electric light, wherein the switch button passes press board groove 101 and is connected with pressing the board 30, press board 30 to connect in press board groove 101 through guide pillar 302, when pressing the board 30, press board 30 to move down along guiding hole 103 through a plurality of guide pillars 302, press board 30 wholly can not take place the slope, when loosening and pressing board 30, press board 30 to get back to the initial position through the switch button, stop gear prevents to press board 30 to break away from above pressing board groove 101.

Further, a gap is left between the guide hole 103 and the guide post 302. Specifically, when the guide hole 103 is connected with the guide post 302, there is a gap, otherwise the guide post 302 cannot be inserted into the guide hole 103.

Further, the distance of the gap is 0.5-1.5 mm. Specifically, the clearance distance between the guide hole 103 and the guide post 302 cannot be too small or too large, the guide hole 103 and the guide post 302 are tightly connected due to too small clearance, the movement is not smooth, the pressing plate 30 is not stable when used due to too large clearance, and the use effect is optimal when the clearance is 0.5-1.5 mm.

As shown in fig. 4, the surface of the guide post 302 connected with the guide hole 103 is formed with a support rib 303 protruding outwards. Specifically, the support rib 303 is formed on the surface of the guide post 302, and when the guide post 302 is inserted into the guide hole 103, the support rib 303 abuts against the inner wall of the guide hole 103, so that the connection is tighter.

Further, the support rib 303 extends from the root of the guide post 302 to the top of the guide post 302. Specifically, the guide pillars 302 are arranged in the guide holes 103 and are connected through the support ribs 303, and the support ribs 303 extend the whole guide pillars 302, so that the connection area between the guide pillars 302 and the guide holes 103 is increased.

Further, the cross-sectional shape of the support rib 303 is a semicircle. Specifically, the semicircular supporting rib 303 has higher compressive strength at the top end and longer service life than the supporting ribs 303 with other shapes, such as a square shape, and the triangular top end is too sharp and is easy to wear.

Furthermore, the number of the support ribs 303 on the guide pillars 303 is 4, and the support ribs are uniformly distributed. Specifically, when the pressing plate 30 is pressed, the force bearing point is not necessarily the right middle of the pressing plate 30, and may be the periphery of the pressing plate 30, the guide post 302 is pressed against the inner wall of the guide hole 103 through 4 support ribs 303, and when the pressing plate 30 is pressed, the pressing plate 30 is always kept horizontal and does not incline.

Furthermore, the number of the guide posts 302 on the pressing plate 30 is 4, and the guide posts are uniformly distributed. Specifically, 4 guide posts 302 are uniformly distributed on the pressing plate 30, the 4 guide posts 302 are simultaneously connected in the guide holes 103, and when the pressing plate 30 is pressed down, the pressing plate 30 moves downwards along the four guide holes 103, so that the stability is better.

Further, the interior of the guide post 302 adopts a hollow design. Specifically, the excessive material inside the guide post 302 is removed, so that the whole pressing plate 30 becomes lighter.

As shown in fig. 2 and 4, the limiting mechanism includes hooks 304 formed at the lower end of the pressing plate 30, and clip interfaces 104 formed in the pressing plate groove 101 and matched with the hooks 304, wherein the number of the hooks 304 is 2, and the hooks are respectively arranged at two ends of the pressing plate 30. Specifically, the limiting mechanism is formed by connecting the pressing plate 30 with a hook 304 between the pressing plate groove 101, and the hook 304 of the pressing plate 30 hooks the bottom surface of the clamping interface 104 to prevent the pressing plate 30 from being separated from the upper part of the pressing plate groove 101.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
