Abstract

The utility model relates to a preventing shaking pivot implement, which comprises a central supporting bracket, a start and stop shaft assembly and a rotating shaft assembly. The start and stop shaft assembly is arranged through the flank of the central supporting bracket and fixed with the pedestal of a lifting-cover equipment each other. The rotating shaft assembly is arranged through the motherboard of the central supporting bracket and fixed with the upper cover of the lifting-cover equipment each other. The limiting crown of the rotating shaft of the rotating shaft assembly is reclined to the margin of the two sides of the central supporting bracket motherboard, supporting the limit crown by the margin, which makes that the rotating does not shake in relation to the rotating of the central supporting bracket, so, the upper cover dose not shake in relation to the rotating of the pedestal.

Description

Prevent the pivot device that rocks

Technical field

The utility model is a kind of pivot device of rocking of preventing, refers between a kind of loam cake and base of being located at lid-lifting device, with so that the pivot device that loam cake rotates with respect to base.

Background technique

Lid-lifting device such as notebook computer, mobile phone etc., have relative loam cake and base, be provided with pivot device between loam cake and base, so that loam cake is able to respect to the base closure or openness, now owing to use the demand of going up, many lid-lifting devices can make loam cake with respect to the base closure or openness except wanting, also need to make loam cake to be able to rotate with respect to base, the pivot device of prior art has the running shaft and the stationary axle of mutual pivot joint, running shaft and loam cake interfix, stationary axle and base interfix, rotate with respect to stationary axle by running shaft, so that loam cake rotates with respect to base, yet, because the relative surface of revolution between stationary axle and running shaft does not contact, when then stationary axle rotates with respect to running shaft, can make stationary axle produce tilt phenomenon because of weight or user's application of force inequality of screen with respect to running shaft, therefore screen produces and rocks, and the user is caused puzzlement in the use.

Summary of the invention

Because the shortcoming of aforesaid prior art, the utility model is improved the pivot device of prior art, so that screen when rotating with respect to base, does not produce and rocks.

For reaching above-mentioned model utility purpose, the utility model designs a kind of pivot device that prevents that screen from rocking, comprising:

One center bolster, it has a base plate, and first flank towards base plate bottom side elongation moulding in the base plate two ends and second flank respectively, on the adjacent two edges in base plate and two ends towards the bottom side respectively elongation moulding the both sides rib is arranged;

One opening-closing shaft group, it is connected with two flanks of center bolster, the opening-closing shaft group has a pin, and connects bolster, a fixed block, a stationary axle and a spacing bolster, pin is arranged in first flank of center bolster, connecting bolster is sheathed on the pin, fixed block is sheathed and be fixed in the pin end, and stationary axle is arranged in second flank of center bolster, and spacing bolster is sheathed on the stationary axle;

One running shaft group, its base plate with the center bolster is connected, the running shaft group includes fixedly bolster of a rotating shaft and, rotating shaft is arranged in the base plate of center bolster, rotating shaft one end radially elongation moulding has spacing bizet, spacing bizet is posted by the limit rib of the base plate of center bolster relatively, and fixedly bolster is sheathed and be fixed in the rotating shaft end.

During use, the connection bolster of opening-closing shaft group and the base of spacing bolster and lid-lifting device are interfixed, the fixedly bolster of running shaft group and the loam cake of lid-lifting device interfix, when loam cake is the axle center rotation with the running shaft group, loam cake rotates with respect to base, this moment, loam cake drive rotating shaft was rotated with respect to the center bolster, advantage of the present utility model is, because the spacing bizet of rotating shaft is posted by the limit rib of the base plate of center bolster relatively, then rotating shaft be subjected to the center bolster the limit rib support and do not rock with respect to the center bolster, so loam cake can keep stable when rotating with respect to base and do not shake fixed.
