Abstract
The utility model relates to a straight pivot device which comprises a shaft sleeve and a shaft rod, wherein the shaft sleeve is hollow and is provided with a sheathing and connecting part and an embedding part, a long notch which penetrates both ends of the sheathing and connecting part is molded on the sheathing and connecting part, and the twisting part of the shaft rod penetrates into the shaft sleeve. The free end of the twisting part is clamped in the embedding part, and the outer diameter of the twisting part is slightly larger than the inner diameter of the shaft sleeve; when the twisting part penetrates into the shaft sleeve, the shaft sleeve is slightly deformed so as to tightly press the twisting part by the long notch; the upper cover of a cover lifting device, which corresponds to a bottom seat, is positioned in a stopping mode by the rotary friction of the twisting part and the inner wall of the shaft sleeve. Because the long notch of the shaft sleeve only penetrates through both of the two ends of the sheathing and connecting part, the shaft sleeve can not generate overlarge deformation after the utility model is long used, and thus, the shaft sleeve can keep a definite friction area between the shaft sleeve and the twisting part of the shaft rod so as to prolong the service life of the straight pivot device.
Description
Technical field
The utility model is a kind of yi word pattern pivot device, refers to a kind of being installed on the lid opening device between lid and base, in order to loam cake is opened relatively and closed in the yi word pattern pivot device of base.
Background technology
The yi word pattern pivot device generally is installed between the loam cake and base of lid opening device, so that loam cake is opened relatively and is closed in base, the yi word pattern pivot device of prior art as shown in Figure 4 and Figure 5, it includes an axle sleeve 50 and an axostylus axostyle 60, axle sleeve 50 hollows and an end are provided with opening 51, form the breach 52 that runs through axle sleeve 50 two ends on axle sleeve 50 sidewalls, axle sleeve 50 other ends are provided with fixed part 53, axostylus axostyle 60 1 ends are torsional part 61, the other end is a fixed part 62, torsional part 61 is arranged in the opening 51 of axle sleeve 50, because the external diameter of torsional part 61 is slightly larger than the internal diameter of axle sleeve 50, when torsional part 61 is arranged in the opening 51 of axle sleeve 50, breach 52 by means of axle sleeve 50 is slightly strutted axle sleeve 50, so that the torsional part 61 of axle sleeve 50 packing axostylus axostyles 60, the yi word pattern pivot device is by means of fixed part 53,62 interfix with the base and the loam cake of lid opening device respectively, when loam cake rotates with respect to base, torsional part 61 is in axle sleeve 50 inner rotations, frictional force by means of torsional part 61 and axle sleeve 50 inside makes the loam cake location stagnate the required angle in the user, but because the breach 52 of axle sleeve 50 runs through axle sleeve 50 two ends, when torsional part 61 spin friction in axle sleeve 50 for a long time, can make axle sleeve 50 easily begin distortion by breach 52 places, and the contact site of minimizing axle sleeve 50 inside and torsional part 61, then can reduce the frictional force of torsional part 61 and axle sleeve 50 inside, the long-term use down, can make that the yi word pattern pivot device is difficult to the loam cake location is stuck in the required angle of user, cause the inconvenience in the use.
The utility model content
In view of the shortcoming of aforementioned prior art, the utility model is improved the yi word pattern pivot device, makes the sustainable stagnation locating effect of keeping of yi word pattern pivot device, to prolong the useful life of yi word pattern pivot device.
For reaching above-mentioned utility model purpose, the technological means that the utility model adopted is a kind of yi word pattern pivot device of design, comprising:
One axle sleeve, its hollow and an end form opening, the other end of axle sleeve forms fixed part, an end that has opening on the axle sleeve is provided with socket part and fitting portion, the internal diameter of socket part is big than the internal diameter of fitting portion, between socket part and fitting portion, form the arcuation breach on the axle sleeve, axially run through forming a microscler breach on the socket part of axle sleeve along side wall surface;
One axostylus axostyle, one end are torsional part, and the free-ended external diameter of torsional part matches with the internal diameter of the fitting portion of axle sleeve, and the other end of axostylus axostyle is a fixed part, and the external diameter of torsional part is slightly larger than the internal diameter of the opening of axle sleeve, and torsional part wears the opening that is arranged in axle sleeve.
The base of axle sleeve and lid opening device interfixes, the loam cake of axostylus axostyle and lid opening device interfixes, because the external diameter of torsional part is slightly larger than the internal diameter of socket part of axle sleeve and the free-ended external diameter of torsional part matches with the internal diameter of the fitting portion of axle sleeve, be sticked in the fitting portion of axle sleeve so torsional part and axle sleeve are the free end of tight fit and torsional part, make loam cake be stagnated the location by means of the frictional force of torsional part and sleeve lining.
Advantage of the present utility model is, by means of microscler breach provide the axle sleeve deformation space with the torsional part tight fit of axostylus axostyle, because microscler breach only runs through the socket part of axle sleeve, make that axle sleeve is difficult for being subjected to for a long time under the axostylus axostyle spin friction, be out of shape improperly and produce, so prolonged the useful life of yi word pattern pivot device, really had its practicality in the use.

Embodiment
See also shown in Figure 1ly, the utility model includes an axle sleeve 10 and an axostylus axostyle 20.
See also shown in Figure 2, aforesaid axle sleeve 10 hollows, one end of axle sleeve 10 forms opening 11, the other end of axle sleeve 10 forms fixed part 12, an end that has opening 11 on the axle sleeve 10 is provided with socket part 101 and fitting portion 102, the internal diameter of socket part 101 is big than the internal diameter of fitting portion 102, forms arcuation breach 13 along side wall surface on the axle sleeve 10 between socket part 10 and fitting portion 102, axially runs through on the socket part 101 of axle sleeve 10 to form a microscler breach 14.
One end of aforementioned axostylus axostyle 20 is a torsional part 21, the external diameter of the free end 212 of torsional part 21 matches with the fitting portion 102 of axle sleeve 10, make the free end 212 of torsional part 21 be sticked in the fitting portion 102 of axle sleeve 10, the other end of axostylus axostyle 20 is a fixed part 22, the external diameter of torsional part 21 is slightly larger than the internal diameter of axle sleeve 10, torsional part 21 wears the opening 11 that is arranged in axle sleeve 10, because the external diameter of torsional part 21 is slightly larger than the internal diameter of axle sleeve 10, when torsional part 21 is arranged in the axle sleeve 10, by means of microscler scarce 14 of axle sleeve 10 axle sleeve 10 is slightly strutted, so that the torsional part 21 of axle sleeve 10 packing axostylus axostyles 20, torsional part 21 is plastic annular recess 211.
