Embodiment

At first, see also Fig. 1, Fig. 2 and shown in Figure 3, Fig. 1 is a schematic perspective view of the present utility model, and Fig. 2 is an assembly decomposing schematic representation of the present utility model, and Fig. 3 is a sectional view of the present utility model.As shown in the figure, the utility model includes fixedly bolster 60 of an axle 10, big bolster 20, banking stop 30, elastic component group 40, fixed block 50 and.

One end of aforesaid axle 10 extends axially and forms a section and present non-circular fixing rod 12, fixing rod 12 peripheries form screw thread, are arranged with aforementioned big bolster 20, banking stop 30, elastic component 40 on the fixing rod 12 in regular turn and in order to the fixed block 50 of aforementioned components positioning and fixing on fixing rod 12.The other end of axle 10 forms the non-conglobate positioning block 14 of section, by positioning block 14 axle 10 and fixing bolster 60 is interfixed.

The aforesaid big bolster 20 that is arranged on the fixing rod 12, its central authorities form one and pass and the non-conglobate perforation of section 22, one sides are formed with an engagement groove (in not shown in the figures) for fixing rod 12.

And, aforesaid banking stop 30, please consult Fig. 4 more in the lump, banking stop 30 includes a salient point pad 32 and a concave wheel piece 34, salient point pad 32 central authorities form one and pass and section presents circular perforation 322 for fixing rod 12, one side has the engagement portion 324 that can engage with the engagement groove on being positioned at big bolster 20, and the another side is formed with an inboard trip projection 326, an outside trip projection 328 can provide month shape oil groove 329 of lubrication with several.And concave wheel piece 34 central authorities are formed with one and pass and section is non-presents circular central perforation 342 for fixing rod 12, and a side include one can with the inboard trip groove 344 of inboard trip projection 326 tablings, one can with the outside trip groove 346 of outside trip projection 328 tablings and several months type oil groove 348.

Continue, see also Fig. 5～Fig. 7, it is that pivot device of the present utility model is applied to embodiment's schematic representation on the laptop computer.When forcing in computer loam cake 72 so that loam cake 72 is opened, to make big bolster 20 drive salient point pad 32 rotates, and make salient point pad 32 and concave wheel piece 34 produce relative displacement, so when inboard trip projection 326, outside trip projection 328 and inboard trip groove 344, when outside trip groove 346 fastens, can prevent that loam cake 72 from continuing to move towards being directed downwards away from base 74, as shown in Figure 6.

And when forcing in loam cake 72, when desire covers loam cake 72 and base 74, the maximum application of force will be applied to make the inboard trip projection 326 of original trip mutually, outside trip projection 328 to break away from chimeric status with inboard trip groove 344, outside trip groove 346, at this moment, inboard trip projection 326, outside trip projection 328 will produce the poor power of rubbing with corresponding concave wheel piece 34 sides, and closing speed is slowed down, to avoid loam cake 72 strong impaction bases 74, as shown in Figure 7.

The utility model is a kind of pivot device, the salient point pad and one that its utilization has asymmetric trip projection has the concave wheel piece of asymmetric trip groove as banking stop, when loam cake is opened, provide loam cake effective locating function, when avoiding loam cake to open effectively, can be because of the application of force excessive or external force slightly when using, and produce loam cake toward disappearance away from base direction continuous slide; And when loam cake is closed with respect to lower cover, can provide enough cushion effects, the speed when covering to slow down.Design more cleverly has several oil grooves on the banking stop of the present utility model in addition, to provide salient point pad and concave wheel piece suitable lubricating.

Above-described, it only is the utility model one preferred embodiment, be not to be used for limiting the scope that the utility model is implemented, every equalization of doing according to the described shape of the utility model claim, structure, feature and spirit changes and modifies, and all should be included in the claim of the present utility model.
