Description

Pivot device with limit function

Technical field

The utility model is a kind of pivot device with limit function, is meant between a kind of loam cake and base of being located at lid-lifting device, so that loam cake and base can open and close and can be limited the pivot device of loam cake rotation angle relatively.

Background technique

Lid-lifting device such as mobile computer, mobile phones etc. are to 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, be subjected to improper external force effect backspin then make electrical assembly produce to damage for fear of loam cake, the pivot device of prior art has limit function, angle of swing with the restriction loam cake, the pivot device of prior art includes two relative banking stops, two banking stops are sheathed on the pivot and can relatively rotate, by spacing protuberance relative on two banking stops, limiting the counterrotating angle of two banking stops, and then the angle of swing of restriction loam cake, yet, the pivot device of prior art must be provided with two banking stops, increase part and then increased fabricating cost, and, increased the complexity on the assembly program simultaneously owing to two banking stops must be assembled to desired location.

The model utility content

Because the shortcoming of prior art, the utility model is improved the pivot device with limit function, to simplify part and assembly program.

For reaching above-mentioned model utility purpose, the technological means that the utility model adopted is a kind of pivot device with limit function of design, comprising:

One pivot;

One rotation bolster, it is sheathed on the pivot, with respect to the pivot elongation moulding one spacing protuberance is arranged on the rotation bolster;

One shim pack, it is sheathed on pivot;

One shell fragment group, it is sheathed on the pivot;

One fixed block, it is sheathed and be fixed in the pivot end;

One banking stop, it is sheathed and be fixed on the pivot, and banking stop directly concaves along periphery and forms spacing recess, and the spacing recess of banking stop is with respect to the spacing protuberance of rotation bolster.

During use, the base of pivot and lid-lifting device interfixes, and the loam cake of rotation bolster and lid-lifting device interfixes, and the driven rotary bolster rotated with respect to banking stop when then loam cake rotated.

Advantage of the present utility model is that by the spacing protuberance of being located at the rotation bolster and the relative engagement of banking stop, the angle of swing with the restriction loam cake then can reduce part, and can simplify assembly program, so the utility model can be simplified overall process and reduce fabricating cost.

Embodiment

See also Figure 1 and Figure 2, the utility model is located at (not shown) between the loam cake of lid-lifting device and the base, and the utility model includes a pivot 10, a rotation bolster 20, a shim pack 30, a shell fragment group 40, a fixed block 50 and a banking stop 60.

Aforesaid pivot 10 interfixes with the base of lid-lifting device, pivot 10 can wear and be fixed in one fixedly in the bolster 11, pivot 10 can be a section and is the non-circular body of rod, fixedly bolster 11 is fixed in the base of lid-lifting device so that pivot 10 and base are interfixed, the outer wall of pivot 10 bodies is around forming screw section 12, the terminal shaft of pivot 10 bodies has an extension rod 13 to elongation moulding, and the diameter of the extension rod 13 of pivot 10 is less than the diameter of the body of pivot 10.

See also Fig. 2 to shown in Figure 5, aforesaid rotation bolster 20 is sheathed on the body of pivot 10, rotation bolster 20 interfixes with the loam cake of lid-lifting device, so that rotation bolster 20 is with respect to pivot 10 rotations, rotation bolster 20 can interfix with a plate body 22, plate body 22 is fixed in the loam cake of lid-lifting device and interfixes with loam cake will rotate bolster 20, rotation has a spacing protuberance 21 with respect to pivot 10 place's elongation mouldings on the bolster 20, and spacing protuberance 21 can be with respect to extension rod 13 places of pivot 10 or with respect to the body place of pivot 10.

Aforesaid shim pack 30 and shell fragment group 40 are sheathed on the body of pivot 10, and aforesaid fixed block 50 is sheathed and be fixed in the end of the body of pivot 10, and fixed block 50 can be a nut, to screw togather on the screw section 12 of being fixed in pivot 10.

See also Fig. 2 to shown in Figure 5, aforesaid banking stop 60 is sheathed and be fixed on the pivot 10, banking stop 60 centers can be run through and form non-circular hole, use sheathed being fixed on the non-circular pivot 10, its embodiment is that banking stop 60 can be sheathed and be fixed on the extension rod 13 of pivot 10 (please referring to Fig. 2 and shown in Figure 3), or it is sheathed and be fixed on the body of pivot 10 (please referring to Fig. 4 and shown in Figure 5), banking stop 60 positions are with respect to the spacing protuberance 21 of rotation bolster 20, banking stop 60 directly concaves along peripheral region and forms a spacing recess 61, and the spacing recess 61 of banking stop 60 is with respect to the spacing protuberance 21 of rotation bolster 20.
