Abstract

The utility model relates to a balance rod structure of keyboard keys. At least one pair of a seat slot and a baffle with a proper spacing is arranged on the surface of a bottom board for a slide rod of a balance rod to slide in a nested and forked manner, the seat slot is provide with a skewed-opening groove, caliber of the skewed-opening groove close to the central side is larger than that of the other side, the baffle is arranged on the same side of the skewed-opening groove in a seated manner so that deflection angle generated by the slide rod in reciprocating motion cannot affect motion smoothness, thereby achieving the effect of stably positioning both side walls.

Description

The balancing pole structure of keyboard

Technical field

The utility model relates to a kind of keyboard, and particularly a kind of balancing pole structure of keyboard mainly is to be provided with in order to keep the smooth start that balancing pole moves up and down stably, by the technical field of sliding between slide bar embedding fork base slotted eye and catch.

Background technology

As Fig. 8～shown in Figure 9; the balancing pole effort formation of general known button; be at least one pair of spacing jaw 611 to be set supply the plant of the slide bar of balancing pole also to slide up and down within it on base plate 61 plate faces; yet spacing jaw 611 as Fig. 8; this slide bar is when start up and down; only be subjected to the spacing of top and inboard; be easy to generate beat vibration and can not stablize; though and the spacing jaw 611 of Fig. 9 has in many ways spacing; but the deflection angle that produced by this slide bar influences; its aperture must enlarge or sidewall will approach; very can not effectively stablize slip; and also be subjected under the effect of deflection angle, can wear or be arranged with a notch 612 in these spacing jaw 611 the place aheads usually, avoid when start, being blocked.

Summary of the invention

The utility model is used base slotted eye and catch that at least one pair of suitable spacing is set on the base plate plate face and is just slided for the embedding fork of slide bar, this base slotted eye system is provided with the angle groove of the bore of close center side greater than the bore of opposite side, and this stop piece base is located at the same side of this angle groove, the deflection angle that is produced when this slide bar reciprocating motion can not influence the fluency of action, more can have the two side to stablize spacing effectiveness; Thin film switch is located at signal switch on the base plate; Elastomer is erected on the thin film switch, makes button can touch logical thin film switch when pushing, and then pushes up during relieving and is back to initial position; Arm support is set up between base plate and button, the height and position when being used for limiting button and moving up and down; Balancing pole is arranged on the medial surface of button, and the two ends slide bar just is arranged between base slotted eye and catch, and embedding pitches spacing slip in the angle groove, makes moving up and down that this button can held stationary when pushing; The medial surface of button is provided with jaw, is used for the clamping balancing pole.

The same side that catch is located at the angle groove toward central offset one segment distance and the seat setting of staggering, and still keep suitable spacing with the base slotted eye, just for the also fork of embedding therein slip of slide bar, to have the staggered stabilization that prolongs positioning section in two side, impel button when pushing, balancing pole more can keep it to move up and down and the start smoothness stably.

Jaw on the outer both sides of the button medial surface arm sheet that respectively stretches out, just edge is butted on the slide bar inboard of balancing pole bending place, impel this slide bar between base slotted eye and catch during reciprocating motion, can slow down the vibration of its beat that produces and can not influence the fluency of action, the effectiveness of stablizing this slide bar and being difficult for skew more can be arranged, when pressing keys, balancing pole more can keep it to move up and down and the start smoothness stably; In addition, this arm sheet upper corners edge can install lead angle, makes balancing pole be easy to put.

The medial surface of button is provided with projection with respect to the appropriate location of slide bar, impel this balancing pole to be easy to outside the assembling, and can be when pushing this button, the last ora terminalis of just effective this slide bar of conflicting, can not influence the fluency of action to slow down its beat that is produced vibration, the effectiveness of stablizing this slide bar and being difficult for skew more can be arranged.

Be provided with groove at the medial surface of button above with respect to base slotted eye and catch, impel when pushing this button, just effectively get out of the way the upper end of this base slotted eye and catch and avoid influencing the fluency of action, more can be widely used on the more slim keyboard.

Both sides, front and back at elongated button medial surface respectively are provided with jaw, be used for clamping two balancing poles, just the left and right sides with respect to base plate is provided with and corresponding base slotted eye of slide bar and catch, impel when pushing this elongated button, this two balancing pole also can keep it to move up and down and the start smoothness stably, and aforesaid various embodiment of mat and arm support is arranged on elastomeric both sides, more can reach and push smooth and easy and constitutionally stable result of use.
