Description
The utility model relates to a kind of keyboard of computing machine.
In the prior art, as " keyboard " (China Patent No. 93245333.3) of Granted publication on September 7th, 1994, it discloses a kind of rectangle key post button (see figure 1).The both sides at place, angle are provided with pin type sliver 114, totally eight around its rectangle key post 11; Establish flexible reed grab 112 in addition in two plane of symmetry places; The bottom is a rectangle key styletable face 115; Its keycap guide bracket 2 is provided with rectangle key post guide groove 21, and its structure is complicated, and materials are more, and key styletable face 115 encloses top cover 41 to closing for evil idea that rectangle and caoutchouc elasticity touch body 4, contacts not ideal.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of simple in structure, and materials are economized, the keyboard of function admirable.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of keyboard comprises keycap, keycap guide bracket and silica gel spring support, and its design feature is the inboard cylindric key post that extends of keycap, and the key post outside is arranged with the location sliver of terminal band grab, and sliver bottom and key post are provided with the slit.The keycap guide bracket is provided with guide groove that matches with key post location sliver and the ladder that makes the grab location.
The utility model has following advantage compared to existing technology:
1. changing rectangle key post and guide groove is cylindric key post and guide groove, and materials are more economized.
2. changing four jiaos of both sides of rectangle, eight pin types sliver is symmetrically arranged two convex slivers, adds that the sliver end carries flexible grab, and location, the fixed sturcture of keycap lump together, and make structure simpler, processes, assembles more convenient.And the contact area that makes sliver, guide groove reduces to littler, and it is more flexible to slide.
3. changing key column length square end surface is the annular end face, makes it that to be that the silica gel spring support of annular supports fashionable with end face, and it is more even to be stressed, and contacts better.
Accompanying drawing 1 is the disclosed three-dimensional structure diagram of documents (93245333.3).
Fig. 2 is the utility model one embodiment three-dimensional structure diagram.
Fig. 3 is that A among Fig. 2 is to view.
Fig. 4 is the utility model one embodiment cross-sectional schematic.
Be described in further detail as follows below in conjunction with accompanying drawing embodiment:
Keycap 1 is a cambered surface rectangle lid, establish cylindric key post 11 in it, the key post outside is symmetrical arranged two convex slivers 12 (being generally the 2-4 bar), it is the grab 13 (being that the hook portion angle is 105 ° greater than 90 ° of present embodiments) of constant slope that the sliver tip designs becomes the upper and lower end face, and both sides, sliver bottom and key post are provided with wide about 0.5 millimeter slit 14, and seam is about half into the key column length.Key post end is provided with the chamfering of being convenient to assemble.
Keycap guide bracket 2 is up-small and down-big ladder barrel shape, and top is provided with two guide grooves 21 that match with key post convex sliver, and the bottom size directly is the ladder 22 of grab location through variation place.Silica gel spring support 3 inside are provided with a projection 32, and projection is connected circuit during pressurized, produces a pulse wave and reaches computer.31 is the annular end face of silica gel spring support among the figure.
It is spill that the utility model also can be made the location sliver, and the keycap guide groove is a convex.It cooperates the cross section is rectangle or circular arc.
