Abstract

The utility model provides a torsion adjustment arm, comprising an axle sleeve provided with a groove, a plurality of C-shaped spring plates provided with a convex block and more than one shallow concave. The convex block is arranged in the groove of the axle sleeve. An axle center is punctured into the C-shaped spring plate. Due to the torsion caused by the axle center being punctured into the C-shaped spring plate to rub, and the adjusted number of the C-shaped spring plate, the torsion can be adjusted. When the C-shaped spring plate is arranged on the axle sleeve, the shallow concave of the C-shaped spring plate forms a line of storing oil groove, with the axle center lubricated, abrasion of the axle center reduced and service life prolonged. Due to the convex block of the C-shaped spring plate arranged in the groove of the axle sleeve, the aim that the torsion adjustment arm gets better torsion is reached.

Description

Torsion is adjusted arm

Technical field

The utility model is that a kind of torsion is adjusted arm, refers to especially a kind ofly adjust torsion and can reduce the axle center wearing and tearing, improve a kind of torsion in working life and adjust arm.

Background technique

General toggle structure, see also shown in Figure 1, its be by: an axle center 11 and an axle sleeve 12 directly are coupling and form, and described axle center 11 1 sides are provided with one first fixed base 13, described axle sleeve 12 1 sides are provided with one second fixed base 14, and described axle sleeve 12 internal diameters are slightly larger than axle center 11 external diameters; When axle sleeve 12 internal diameters do not conform to axle center 11 external diameters, promptly can't sheathedly use, so it to be during fabrication, its internal diameter and external diameter need quite accurate, and axle sleeve 12 directly is set in

axle center

11, and 11 wearing and tearing of then described axle center are quite high, and promptly lose torsion;

Moreover, TaiWan, China patent gazette certificate M273752 number, a kind of internal cover type section of nothing pivot, formed with pivot, pin axial sleeve, packing ring set etc.: described pivot, the positioning part is set on pivot, establishes the plurality of fixed hole on it, pivot is provided with a cylindrical body with respect to the place, positioning part; Described pin axial sleeve is provided with plural pieces torsion adjusting strip with span, forms a hole between each torsion adjusting strip, and cylindrical body is mounted on the hole between each torsion adjusting strip, forms the tapering outside the branch at each torsion adjusting strip; Described packing ring set is mounted on the outside place of each torsion adjusting strip, is formed with the taper hole in the aforementioned tapering that cooperatively interacts in packing ring set inside;

But the described above-mentioned internal cover type section of nothing pivot though its tool torsion adjusting strip and when desire is adjusted torsion, needs torsion adjusting strip car is again established, and causes the inconvenience used;

So, how disappearance such as above-mentioned is forgone, and provided a kind of when adjusting torsion, advance to reduce the axle center wearing and tearing, improve working life, be the place of the technical difficulties that this case model utility designer institute desire solves.

Summary of the invention

Main purpose of the present utility model is promptly providing a kind of torsion to adjust arm, reduces the axle center wearing and tearing, improves working life

For achieving the above object, the technical solution adopted in the utility model is:

A kind of torsion is adjusted arm, and it comprises: an axle sleeve, and described axle sleeve is provided with a groove; A plurality of C shape shell fragments, described C shape shell fragment is provided with a projection and an above scrobicula, and described projection is arranged in the groove of axle sleeve; One axle center, described axle center are located in the described C shape shell fragment.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:

Prior art:

1, sleeve diameter and axle center external diameter need quite accurate.

2, the axle center wearing and tearing are higher.

3, the torsion adjustment is difficult for.

The utility model advantage:

1, reducing the axle center weares and teares, improves working life.

2, can adjust torsion.

3, its distribution oil storage.

4, can form oil storage tank.

5, described a plurality of C shape shell fragment can be done increase and decrease and adjust torsion.

Embodiment

For the effect that makes convenient simple and direct understanding further feature content of the present utility model of your auditor and advantage and reached can more manifest, with the utility model conjunction with figs., be described in detail as follows now:

See also Fig. 2, shown in Figure 3, the utility model provides a kind of torsion and adjusts arm, and it comprises:

One axle sleeve 3, described axle sleeve 3 is provided with a groove 31, and described groove 31 can be fixing for the projection 41 of C shape shell fragment 4, and described axle sleeve 3 one sides are provided with one first fixing part 32;

A plurality of C shape shell fragments 4, described C shape shell fragment 4 are provided with a projection 41 and an above scrobicula 42, and as shown in Figure 4, described projection 41 is provided with and is arranged in the groove 31 of axle sleeve 3, and as shown in Figure 5, described C shape shell fragment 4 external diameters are slightly less than axle sleeve 3 internal diameters;

One axle center 2, described axle center 2 is level and smooth shape, described again axle center 2 one sides are provided with one second fixing part 21, and described axle center 2 is located in the described C shape shell fragment 4, and described axle center 2 external diameters are slightly less than C shape shell fragment 4 internal diameters, as shown in Figure 6, but described axle center 2 circumference cars are provided with the shallow line 23 of ring-type, as shown in Figure 8, or the shallow line 22 of spiral, as shown in Figure 9, can assist oil storage and C shape shell fragment 4 internal diameters lubricated;

First fixing part 32 of its axle sleeve 3 of the utility model is can be separately fixed on the screen 51 and keyboard 52 of mobile computer with second fixing part 21 in axle center 2, and as shown in Figure 7;

Rely on described axle center 2 to be located in described C shape shell fragment 4 internal frictions and produce torsion, and rely on the increase and decrease of adjusting described a plurality of C shape shell fragments 4 then can adjust torsion, be arranged in the groove 31 of axle sleeve 3 again by means of the projection 41 of described C shape shell fragment 4, make torsion adjust arm and can reach preferable torsion; When a plurality of C shape shell fragments 4 were arranged in the axle sleeve 3,42 of the scrobiculas of then described a plurality of C shape shell fragments 4 can form a row oil storage tank, wore and tore in order to do lubricating axle center 2 simultaneously and reducing axle center 2, and then improved working life.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.
