Abstract
The utility model provides a torque force arm structure of multi-angle sleeve, comprising a shaft sleeve which is provided with a hollow part; an elastic sleeve which is a polygonal and polyhedron with two communicated ends, and a plurality of shallow and concave oil grooves are arranged in the elastic sleeve; the elastic sleeve is arranged in the hollow part of the shaft sleeve; an axis which is perforated in the elastic sleeve; the axis is arranged in the shaft sleeve through the elastic sleeve and the axis is perforated in the elastic sleeve; the elastic sleeve can expand outward and the elastic sleeve expanding outward is limited by the shaft sleeve, so that a constrictive force is produced between the shaft sleeve and the elastic sleeve, and a tension is produced to the elastic sleeve by the axis; the elastic sleeve is a polygonal and polyhedron; when a surface between the axis and the elastic sleeve loses the friction, other surfaces still can maintain the torque force and a plurality of shallow and concave oil grooves are arranged in the elastic sleeve to lubricate the axis, so the utility model has the advantages that the loss can be reduced and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of polygonal sleeve toggle structure, relate in particular to a kind of by the mutual friction and produce the toggle structure of torsion mutually of axle center and resilient sleeve, and this resilient sleeve is polygonal polyhedron, so when certain simultaneously loses frictional force in axle center and the resilient sleeve, still have other several can keep torsion, be that resilient sleeve is produced a constrictive force because of this axle sleeve again, make resilient sleeve tight to the axle center, and the torque magnitude when more firmly rotating, and be provided with several scrobicula oil grooves in this resilient sleeve, and abrasion are reduced in the Castor Oil axle center, and then reach a kind of purpose of polygonal sleeve toggle structure.
Background technique
Usually, general toggle structure sees also shown in Figure 1, its be by: an axle center 11 and an axle sleeve 12 directly are coupling and form, these axle sleeve 12 1 sides are provided with one second fixed base 14, and these axle center 11 1 sides are provided with one first fixed base 13, and these 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 sheathed on axle center 11, and then these axle center 11 wearing and tearing are quite high, and promptly lose torsion;
Moreover TaiWan, China patent gazette certificate M273752 number provides a kind of internal cover type section of nothing pivot, it is formed with pivot, pin axial sleeve, packing ring set etc.: this 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; This 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 placed on the hole between each torsion adjusting strip, forms the tapering outside the branch in each torsion adjusting strip; This packing ring set is placed 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;
Yet the internal cover type section of the nothing pivot that this is above-mentioned 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.
Summary of the invention
Main purpose of the present utility model is the defective that overcomes above-mentioned prior art, and a kind of polygonal sleeve toggle structure is provided, and it is torque magnitude and can reduce wear, improve working life firmly.
The purpose of this utility model realizes that by following technical proposals polygonal sleeve toggle structure provided by the utility model comprises:
One axle sleeve is provided with a hollow portion in this axle sleeve;
One resilient sleeve, this resilient sleeve are the polygonal polyhedron that two ends connect, and are provided with several scrobicula oil grooves in this resilient sleeve, and this resilient sleeve is to be contained in the hollow portion of axle sleeve again;
One axle center, this axle center are to be arranged in the resilient sleeve;
By being placed in the axle sleeve by this resilient sleeve and this axle center is to be arranged in the resilient sleeve, this resilient sleeve is expanded outwardly, and the resilient sleeve that expands outwardly is limited by axle sleeve, in order to do and make this axle sleeve and resilient sleeve produce a constrictive force and the axle center produces a tension force to resilient sleeve, so when the rotation of this axle center be and resilient sleeve mutual friction and produce torsion mutually, and because of this resilient sleeve is polygonal polyhedron, so when certain face loses frictional force in axle center and the resilient sleeve, still have other several can keep torsion, be that resilient sleeve is produced a constrictive force because of this axle sleeve again, make resilient sleeve tight to the axle center, and the torque magnitude when more firmly rotating, and be provided with several scrobicula oil grooves in this resilient sleeve, and can make lubricated axle center reduce abrasion, and then reach a kind of purpose of polygonal sleeve toggle structure.
Below just relevant technology contents of the present utility model and detailed description, existing conjunction with figs. and given embodiment describe as follows.

Embodiment
See also shown in Fig. 2,3, the utility model provides a kind of torsion to adjust arm, and it comprises:
One axle sleeve 3 is provided with a hollow portion 32 in this axle sleeve 3, and these axle sleeve 3 one edge are provided with one first fixing part 31, and the internal diameter of this axle sleeve 3 makes the external diameter that is slightly larger than resilient sleeve 4 again;
One resilient sleeve 4, the polygonal polyhedron that this resilient sleeve 4 connects for two ends, and be provided with several scrobicula oil grooves 41 in this resilient sleeve 4, this resilient sleeve 4 makes in the hollow portion 32 that is placed in axle sleeve 3 again, and this resilient sleeve 4 offers a rectangular elasticity breach 42;
One axle center 2, this axle center 2 is level and smooth shape, and these axle center 2 one edge are provided with one second fixing part 21, this axle center 2 is to be arranged in the resilient sleeve 4 again, and the external diameter in this axle center 2 is slightly larger than the internal diameter of resilient sleeve 4;
