Description

Key switch mechanism

[technical field]

The utility model relates to a kind of key switch mechanism, particularly a kind of not key switch mechanism on a line of direction and the switching component direction of motion of pushing.

[background technology]

The general expression key switch is external world's direction of exerting pressure with the direction of motion of internal switch is consistent, does not have angle.Its press-key structure has two main devices to constitute, and the one, button, the 2nd, switching component, thereby by the contact button and promote the unlatching of control internal switch components and parts.There are enough spaces to lay switching component on the direction of exerting pressure with regard to requiring like this,, switching component or littler switching component can't be installed then, tend to cause cost to increase if when the space is big inadequately.

In view of this, in fact be necessary to propose a kind of key switch mechanism, we can overcome direction of exerting pressure and the switching component direction of motion and need consistent shortcoming to utilize this key switch mechanism, have expanded the scope of application and need not change the first device of littler more expensive switch, have saved cost waste.

[summary of the invention]

Therefore, the purpose of this utility model is to provide a kind of key switch mechanism, and this key switch mechanism adopts lever principle to operate, and overcomes direction of exerting pressure and the consistent shortcoming of switching component direction of motion needs.

For reaching above-mentioned purpose, key switch of the present utility model mechanism comprises:

One guide pillar, one end are a press section, and the both sides of this guide pillar center position are respectively equipped with rotating shaft, and this guide pillar other end is provided with an inclined-plane;

One support, the both sides of one end are respectively equipped with overhead kick, and this overhead kick matches with above-mentioned rotating shaft and constitutes a rotating shaft mechanism, and the both sides of the other end are respectively equipped with one first grab, and this frame bottom is provided with some second grabs;

One switching component, the one end is provided with button, and this switching component is stretched in the above-mentioned support by button one end, and this switching component is fixed in the support by above-mentioned first grab;

One carrier base, its surface is provided with some jacks, the fixing above-mentioned support thereby these some jacks combine with above-mentioned second grab.

Say that especially key switch of the present utility model mechanism also comprises: the bottom of press section one end of above-mentioned guide pillar also is provided with a limited post.

Compared to prior art, key switch of the present utility model mechanism adopts lever principle, has overcome direction of exerting pressure and the consistent shortcoming of switching component direction of motion needs, has expanded the scope of application and need not change littler more expensive switch module.

For the purpose of this utility model, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[description of drawings]

Fig. 1 illustrates the exploded view of key switch of the present utility model mechanism.

Fig. 2 illustrates the structure chart of the utility model key switch mechanism.

Fig. 3 illustrates the end view of the utility model key switch mechanism.

End view when Fig. 4 illustrates the utility model key switch mechanism operating state.

[embodiment]

See also Fig. 1, it is the exploded view of the utility model key switch mechanism.The utility model mechanism for testing comprises:

One guide pillar 1, one end are a press section 11, and the both sides of this guide pillar 1 center position are respectively equipped with rotating shaft 12, and this guide pillar 1 other end is provided with an inclined-plane 13, and the bottom of press section 11 1 ends of this guide pillar 1 also is provided with a limited post 14;

One support 2, the both sides of one end are respectively equipped with overhead kick 21, this overhead kick 21 matches with above-mentioned rotating shaft 12 and constitutes a rotating shaft mechanism, inclined-plane 13 ends of above-mentioned guide pillar 1 place this support 2 simultaneously, the both sides of the other end of this support 2 are respectively equipped with one first grab 22, and these support 2 bottoms are provided with some second grabs 23;

One switching component 3, the one end is provided with button 31, and this switching component 3 is stretched in the above-mentioned support 2 and with the inclined-plane 13 of above-mentioned guide pillar 1 by button 31 1 ends and contacts and interact, and this switching component 3 is fixed in the support 2 by above-mentioned first grab 22;

One carrier base 4, its surface are provided with some jacks 41, thereby these some jacks 41 combine with above-mentioned second grab 23 and fix above-mentioned support 2.

Say that especially above-mentioned limited post 14 is used to limit the range of movement of guide pillar 1, when preventing that pressure is excessive, guide pillar 1 has rotated through the range of switch and has made this key switch failure mechanisms.

As shown in Figure 4, direction of arrow F1 is a direction of exerting pressure; Direction of arrow F2 is the direction of motion of switching component 3, and this direction of exerting pressure F1 becomes 90 degree angles with the direction of motion F2 of switching component 3.

As Fig. 3, shown in Figure 4, rotating shaft 12 rotatablely moves in overhead kick 21 after press section 11 being applied the power of a direction of arrow F1, thereby drive other end inclined-plane 13 motions of guide pillar 1, because the button 31 that inclined-plane 13 tilts so at a certain angle with regard to pull switch components and parts 3 moves along arrow F2 direction, thereby open switching component 3, when an end press section 11 of guide pillar 1 moves to certain position, limited post 14 can contact with carrier base 4 and stop press section 11 1 ends to continue to move along arrow F1 direction, prevents the surpassing its range of button 31 of switching component 3 and destroys this key switch mechanism.

The direction of motion F2 angulation of direction of exerting pressure F1 and switching component 3 is not 90 when spending in this key switch mechanism, and the angle of inclination that only needs to adjust the inclined-plane 13 of guide pillar 1 one ends gets final product.
