Description

Key device

The utility model relates to a kind of assembled key device that is easy to, and can be in the process of pushing maintenance level and can not block key.

Keyboard is a kind of input unit that general information electronic installation (as computer) the most generally uses, its button of general keyboard directly is socketed on the keyboard base, the cylinder socket spring that extends by key lid bottom and moving up and down, but the cylinder of key lid must go deep into the base certain depth, otherwise can cause the card key, and this keyboard also has certain thickness.Along with information electronic device towards portable, portable development, the conventional keyboard of aforementioned type has not met this development trend, therefore just there is the keyboard of cross link mechanism to produce, can reduces the thickness of keyboard, when button moves up and down, have the function of maintenance level again.But still there is shortcoming in this design, and wherein as the key device of No. the 80206310th, Taiwan patent application, it has the saddle that separates with the key lid, and therefore assembling needs to increase more step.

And for example No. the 83204123rd, Taiwan patent application and United States Patent (USP) the 5th, 457, No. 297 design, this cross link mechanism is with the pivot combination, wherein two ends are individually fixed in base, key lid, and therefore cross link mechanism will could combine with base, key lid through twice accurate contraposition when assembling, do the complexity that increases assembling like this, expend long man-hour.United States Patent (USP) the 4th for another example, 433, No. 225 key lid had additional the rod member that both sides have chute, and be installed in the cross link mechanism of pivoting, when button is pressed into the stroke of half, the key lid can produce the loosening of horizontal direction, make a mistake United States Patent (USP) the 5th, 278 when making button, though 371 design has different structures, but still can cause the loosening problem of key lid when pushing.

Also have, spring assembly being added in the design of cross link mechanism, as United States Patent (USP) the 5th, 382,762 and 5,466, No. 901, its spring is installed in the end of base against connecting rod, have buffering effect, energy held stationary when making the pressing key lid, just its assembly element and required step thereof are too many, need accurate contraposition in addition, increase complexity and degree of difficulty on making.Other relevant prior aries also have No. the 84218262nd, 84214256 and 85202834, Taiwan patent application etc., and United States Patent (USP) the 4th, 580,022,4,902,862,5,278,372,5,278,374,5,399,822,5,463,195,5,488,210,5,504,283,5,512,719,5,555,971 and 5,562, No. 203 etc.

The purpose of this utility model is to provide a kind of key device, and it is not only simple in structure, is easy to assembling, and can prevents the card key.

The purpose of this utility model is achieved in that promptly provides a kind of key device, is installed on the electronic installation, it is characterized in that it comprises: pedestal, described pedestal have relative fixing district and at least one guidance part; First sliding part has first holding division, at least one chute and at least one slide block on it, wherein said first holding division is fastened in the fixing district of described pedestal; Second sliding part has second holding division, at least one projection and at least one slide block on it, wherein said second holding division is fastened in another relative district that fixes of described pedestal, and described projection is installed in the chute of described first sliding part; The key lid has at least one guide element on it, and at least one sliding area, and wherein said guide element is installed in the guidance part of described pedestal, and described sliding area is in order to take in the slide block of described first sliding part and described second sliding part.

The advantage of the utility model device is that it is the maintenance level in the process of pushing, and does not have any looseningly, installs easily simultaneously, does not need accurate contraposition to finish, and simplifies assembling, saves man-hour.

Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described, wherein:

Fig. 1 is the three-dimensional exploded view of the utility model key device;

Fig. 2 is a stereogram of the present utility model, and wherein the key lid is for being inverted;

Fig. 3 is the constitutional diagram of the utility model key device, wherein the key lid is cut open.

Consult Fig. 1, the utility model key device 99 comprises pedestal 10, first sliding part 20, second sliding part 30 and key lid 40.Wherein, pedestal 10 is a square plate linear element, convex with on it and fix projection 121, this fixes projection 121 and forms two as the

fixing district

12,13 that links the district, fixing 12,13 both sides, district, the central part of pedestal 10 is provided with guidance part 14, and this guidance part 14 is a column bossy body, also is provided with the conduit 141 as guide channel on it.First sliding part 20 is the Qian shape member of bending, the central part of its Qian shape is as the holding division 22 that links, in order to be fastened in the fixing district 12 of aforementioned pedestal 10, and first sliding part 20 can be rotated, the both sides of first sliding part 20 are provided with the rod member 24 with chute 26, and the other end that connects holding division 22 at rod member 24 relatively is provided with slide block 28.

Second sliding part 30 is the Qian shape member of bending too, its central part is as the holding division 32 that links, in order to be fastened in another fixing district 13 of aforementioned pedestal 10 as the binding district, second sliding part 30 can be rotated, and the both sides of second sliding part 30 are the rod member 34 that is provided with projection 36, and borrow this projection 36 to be assemblied in the chute 26 of aforementioned first sliding part 20, the other end that connects holding division 32 at rod member 34 relatively also is provided with slide block 38, in addition, be provided with strong 35 in addition 34 of rod members, the rod member 34 that connects second sliding part, 30 both sides respectively is in order to reinforced structure.

Please consult Fig. 2 simultaneously, key lid 40 has pushes surface 41, finger pushes when using in order to bear, be provided with sliding area 42 in both sides, in order to the

slide block

28,38 of taking in first sliding part 20 and second sliding part 30, the central part that covers 40 both sides at key is provided with the guide pillar 44 as guide element, can be accommodated in the guidance part 14 of aforementioned pedestal 10.When pushing of finger presses key lid 40 surperficial 41 the time, because guide pillar 44 is subjected to guide channel 141 restriction in the horizontal direction of guidance part 14, only can produce displacement in vertical direction, and along with the downward displacement of finger presses, 28,38 sliding area 42 horizontal slips of the slide block of first sliding part 20 and second sliding part 30 along key lid 40,36 of the projections of second sliding part 30 slide in the chute 26 of first sliding part 20, because chute 26 has specific curved-surface structure, therefore, key lid 40 is being remained level in the sliding process of bottom offset.In addition, in the process of assembling, can assemble first sliding part 20 and second sliding part 30 earlier, again key lid 40 be pushed first, second sliding part and is filled to pedestal 10, its mounting direction is same direction, and is very convenient.
