Description
Technical field
The utility model is that especially a kind of at least one end that is used in the beam barrel portion of a female axle is provided with a jog about a kind of pivot structure of tool compensation torsion, the pivot structure of a kind of tool compensation torsion that this jog and cam cooperatively interact.
Background technique
In daily life, be able to folding, can between two articles, install a pivot structure usually in order to make collapsible object.Please refer to Fig. 1, a kind of known pivot structure, it comprises, a female 1a and a public 4a.Female axle 1a comprises an axial region 11a and a linking department 12a, and this public affairs axle 4a comprises an axostylus axostyle 41a and a linking department 42a.But be incorporated into to the axostylus axostyle 41a turn of public axle 4a the axial region 11a of female axle 1a, the linking department 42a of public axle 4a is incorporated into one first object, and the linking department 12a of female axle 1a is incorporated into one second object.Therefore, the axle center that first object can axostylus axostyle 41a is that the center rotates, make between first object and second object and be able to folding, thereby to form above-mentioned collapsible object.
On practice utilization aspect; can relatively produce positioning relation in order to make between public axle 4a and the female axle 1a; usually at least necessarily position mechanism can be set between axostylus axostyle 41a is with respect to the rotating distance of axial region 11a rotation; it can comprise one group of cam 2a; one group of relative dish-shaped shell fragment 3a and is locked in axostylus axostyle 41a one nut 6a; and described cam 2a comprises one first cam 21a and one second cam 22a; having male and fomale(M﹠F) between the first cam 21a and the second cam 22a cooperatively interacts; the first cam 21a engages with the sidewall of axial region 11a by a wear plate 5a; wear plate 5a provides a large amount of frictional force; and allow the first cam 21a follow female axle 1a rotation; and along with relatively rotating between the first cam 21a and the second cam 22a, and make that producing a location between female 1a and public axle 4a concerns.Along with relatively rotating between the first cam 21a and the second cam 22a, the second cam 22a oppresses this and organizes dish-shaped shell fragment 3a, produces a rebounding force and make this organize dish-shaped shell fragment 3a in addition, and generation one torsion between feasible female axle 1a and the public axle 4a.
Yet, this mother's axle 1a and public axle 4a are via relatively rotating repeatedly, can make the frictional force between this wear plate 5a and this first cam 21a and this axial region 11a day by day to reduce, and when causing this mother's axle 1a to rotate, this wear plate 5a can't make this first cam 21a and this second cam 22a rotate, and makes that can't produce a location between mother axle 1a and public axle 4a concerns and a torsion.
In addition, this mother's axle 1a only organizes dish-shaped shell fragment 3a by this with the torsion of public axle 4a and produces, therefore cause the torsion between female axle 1a and the public axle 4a too small, when this pivot structure is applied to as notebook computer, when its screen loam cake is opened, can glide because of too small torsion, thereby cause user's inconvenience, general known settling mode is to use extra fixed structure, produces extra torsion.
Therefore, the real defectiveness of above-mentioned known pivot structure and should being corrected.
