In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a prevent structure of cluster key double combination button, includes shell, disjunctor double button combination, feels cushion and PCBA board, the ring channel has been seted up at the top of shell, disjunctor double button combination sets up on the shell, the cushion of feeling sets up in PCBA board, be provided with electronic key on the PCBA board.

Preferably, the connected double-key combination comprises two peripheral supports and two keys, and the peripheral supports are fixedly connected with the shell.

Preferably, the hand feeling cushion is fixed on the electronic key in a sticking way.

Preferably, four hand feeling soft pads and four electronic keys are arranged.

Preferably, the top of the key penetrates to the outside of the annular groove.

Preferably, the positions close to four corners of the bottom of the peripheral support are fixedly connected with height positioning support columns.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the conjoined double-key combination of the utility model is parallel to the key handle of the PCBA through the hand feeling soft cushion, and the soft cushion is deformed under stress when being pressed, so that the stroke of the key is increased, and the hand feeling of pressing is increased;

2. the two swing arms are symmetrical in the left and right centers, and meanwhile, the material reduction and the sharpening of the two sides of the contact part of the swing arms and the keys are one half of the width of the arms, so that the connected double-key combination is more natural and free from obstruction when being pressed up and down, and the pressing hand feeling is improved;

3. the utility model designs several height positioning support columns on the peripheral bracket, the yellow surface of the support column is pasted on the PCBA board after assembling to fix the height of the key, and simultaneously the height of the interlocking prevention fulcrum on the conjoined double-key is 0.05 lower than that of the support column of the peripheral bracket, namely the interlocking prevention fulcrum has a gap of 0.05 from the PCBA after assembling, and the interlocking prevention fulcrum can be integrally moved down by 0.05 when the key is pressed, thereby increasing the hand feeling of pressing;

4. the displacement of the function of the PCBA key of the utility model is 0.15, when the conjoined double-key combination moves down by 0.05, the linkage fulcrum is prevented from propping against the PCBA, the key is prevented from moving down integrally, at the moment, the lower two electronic keys can not function, when the key is pressed again, the corresponding electronic keys are pressed down continuously according to the stressed end, the other end is not moved down, thus preventing the two electronic keys on the PCBA from being pressed simultaneously to form a string key;

5. the utility model discloses the interlock fulcrum top design of preventing of disjunctor double key combination is the convex fulcrum of R0.5, can make littleer effort press the button, and the button that increases from top to bottom is felt this structure of preventing cluster key double combination button.

6. The utility model has simple structure, lower cost, more convenient production and simple assembly; the combined key adopts a hard glue material and far exceeds the hand feeling of a soft glue material.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a prevent structure of cluster key double-unit key, which comprises an outer shell 1, disjunctor double-unit key combination 2, feel cushion 3 and PCBA board 4, disjunctor double-unit key combination 2 includes peripheral support 5 and button 6, the outside to the ring channel is run through at the top of button 6, button 6 is provided with two, fixed connection between peripheral support 5 and the shell 1, the ring channel has been seted up at the top of shell 1, disjunctor double-unit key combination 2 sets up on shell 1, it sets up in PCBA board 4 to feel cushion 3, be provided with electronic key on PCBA board 4, it fixes on electronic key to feel cushion 3 paste, it all is provided with four with electronic key to feel cushion 3, the equal fixedly connected with high positioning support column by the four corners position of leaning on of peripheral support 5 bottom.

When the double-key combination is installed, the connected double-key combination 2 is connected with the shell 1, and then the double-key combination 2 is connected with the PCBA board 4.

In summary, the following steps: firstly, the conjoined double-key combination 2 of the utility model is level with the key handle of the PCBA through the hand feeling soft cushion 3, and the soft cushion is deformed under stress when being pressed, so that the stroke of the key is increased, and the hand feeling of pressing is increased; secondly, the two swing arms of the conjoined double-key combination 2 of the utility model are symmetrical in the left and right centers, and meanwhile, the material reduction and the sharpening of the two sides of the contact part of the swing arms and the keys and the width of the swing arms are half of the arm width, so that the conjoined double-key combination 2 is more natural and free from obstruction when being pressed up and down, and the pressing hand feeling is improved; then, the peripheral bracket 5 of the utility model is provided with a plurality of height positioning support columns, the yellow surface of the support column is pasted on the PCBA board 4 after being assembled to fix the height of the key, and simultaneously, the height of the anti-linkage fulcrum on the conjoined double-key is 0.05 lower than that of the support column of the peripheral bracket 4, namely, the distance between the anti-linkage fulcrum and the PCBA after being assembled has a gap of 0.05, the whole body moves down by 0.05 when the key is pressed, and the hand feeling of pressing is increased; still, the utility model discloses a displacement of PCBA button effect is 0.15, prevents the interlock fulcrum to withstand PCBA after disjunctor double key combination 2 moves down 0.05 as a whole, prevents that the button from moving down as a whole, and two electronic keys below this moment still can not play a role, then continue to move down according to atress one end when pressing again and press corresponding electronic key, and the other end then no longer moves down, so prevented to press two electronic keys on PCBA simultaneously and formed the cluster key, finally, the utility model discloses the top of the interlock fulcrum of preventing of disjunctor double key combination 2 designs into R0.5 convex fulcrum, can make less effort press the button, increases the upper and lower button and feels this structure of preventing cluster key double combination button, simple structure, and the cost is lower, and it is more convenient to produce, assembles simply; the combined key adopts hard glue material and far exceeds the hand feeling of soft glue material.
