Abstract

The utility model relates to a pivot apparatus which provides a pivot apparatus arranged between an upper cover and a bottom seat of an article with a cover, such as mobile telephones, notebook computers, etc. The utility model comprises a bottom board which is fixed on the bottom seat, a rotating seat, a roll ball and an annular sheet, wherein a pivot shaft penetrates and is fixed in the bottom board, and the pivot shaft is provided with two opposite through holes. The rotating seat is provided with a C-type annular shaft sleeve and a fixed part, the fixed part is mutually fixed with the upper cover, and the shaft sleeve is clamped outside the pivot shaft and is provided with a through hole. The annular sheet is clamped outside the shaft sleeve and is provided with a through hole, the roll ball is clamped between the annular sheet and the shaft sleeve, and the roll ball is embedded with the through holes of the shaft sleeve and the annular sheet. When the upper cover is rotated, the roll ball is clamped by the rotating seat and the annular sheet rotate to rotate following the rotating seat and the annular sheet together, the roll ball is embedded with each through hole of the pivot shaft so as to achieve a positioning function, and thus, the upper cover can rotate correspondingly to the bottom seat by the pivot device.

Description

Pivot device

Technical field

The utility model is a kind of pivot device, is meant a kind of being installed between the loam cake and base that covers article, makes the loam cake can be with respect to the pivot device of base rotation.

Background technology

General mobile phone, translating machine and mobile computer, have loam cake and base two parts mostly, be provided with pivot device so that loam cake is closure or openness with respect to base between loam cake and base, yet science and technology is day by day flourishing now, mobile phone and mobile computer have increased many additional functions, for example have mobile phone of camera function or the like, loam cake only can can't effectively be brought into play all additional functions with respect to the base closure or openness, so the pivot device of commonly using truly has the necessity of improvement.

The utility model content

Because the aforesaid deficiency of commonly using the pivot device function, the utility model is a kind of revolving pivot device of design, and loam cake can be rotated with respect to base, to allow the additional function that covers article be given full play to, increases simultaneously to have and covers the convenience that article use.

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

One base plate forms a perforation on it, the perforation periphery forms two outward extending relatively protuberances;

One pivot, it is hollow columnar, and it wears in the perforation of being fixed in base plate, forms two relative perforation on the pivot side wall surface;

One rotating seat, it comprises a C type ring-type axle sleeve, and axle sleeve two ends stretch out and form fixed part, form a perforation on the wall of axle sleeve with respect to two terminal opposite sides, wall root edge with respect to perforation on the axle sleeve forms outward extending protuberance, and axle sleeve is clamped in the pivot outside;

One ball;

One ring plate, it is clamped in the axle sleeve outside, ring plate two ends are resisted against the axle sleeve and the fixed part joint of rotating seat, the side wall surface of ring plate forms a perforation, ball is between ring plate and axle sleeve, and the perforation tabling of the perforation of ball and axle sleeve and ring plate, the diameter of the perforation of axle sleeve are greater than the diameter of ball, and the diameter of the diameter of the perforation of ring plate and the perforation of pivot is less than the diameter of ball.

Base plate is fixed in to be had on the base that covers object, the fixed part of rotating seat be fixed in have cover object on cover, rotation is during loam cake, rotating seat and ring plate clamping ball together rotate, ball rotates to the perforation tabling with pivot, to reach positioning function.

Advantage of the present utility model is, is arranged between the base and loam cake that covers article by the utility model, makes loam cake to rotate with respect to base, to increase the convenience on using, makes that simultaneously the function of article is given a full play of.

Embodiment

See also Figure 1 and Figure 2, the utility model comprises a base plate 10, a pivot 20, a rotating seat 30, a ball 40, reaches a C type ring plate 50.

Form a non-circular perforation 11 on the aforesaid base plate 10, the 11 both sides inwalls of boring a hole form relative plane 111, and 11 peripheries of boring a hole form two outward extending relatively protuberances 12.

Aforesaid pivot 20 is hollow columnar, the bottom of its outside wall surface forms two relative planes 21, pivot 20 mat planes 21 are arranged in the non-circular perforation 11 of base plate 10, and pivot 20 is fixed on the base plate 10, form two relative perforation 22 on pivot 20 side wall surfaces, pivot 20 tops form ring flange 23.

Aforesaid rotating seat 30 comprises a C type ring-type axle sleeve 31,31 liang of ends of axle sleeve stretch out and form fixed part 32, form a perforation 311 on the wall of axle sleeve 31 with respect to two terminal opposite sides, wall root edge with respect to perforation 311 on the axle sleeve 31 forms outward extending protuberance 312, axle sleeve 31 is clamped in pivot 20 outsides, and the ring flange 23 of pivot 20 is resisted against axle sleeve 31 apical margins.

Aforesaid ring plate 50 is clamped in axle sleeve 31 outsides, 50 liang of ends of ring plate are resisted against the axle sleeve 31 and fixed part 32 joints of rotating seat 30, the side wall surface of ring plate 50 forms a perforation 51, ball 40 is between ring plate 50 and axle sleeve 31, and ball 40 and the perforation 311 of axle sleeve 31 and perforation 51 tablings of ring plate 50, the diameter of the perforation 311 of axle sleeve 31 is greater than the diameter of ball 40, and the diameter of the perforation 22 of the diameter of the perforation of ring plate 50 and pivot 20 is less than the diameter of ball 40.
