Abstract

The utility model discloses an improved structure of a roller wheel, which comprises a rolling ball, wherein after the rolling ball is arranged in a wheel shell and is covered by a wheel shell cover, the rolling ball is limited in the wheel shell without discharge. The upper part of the wheel shell is convexly provided with at least three top wheel chambers, and each top wheel chamber is provided with one top wheel respectively. When the rolling ball is arranged in the top wheel chamber, the rolling ball forms an interval with the wheel shell without mutual contact under the push of the three top wheels. Thus, the nondirectional rolling mode of a ball wheel is utilized, and because of the nondirectional rolling of a rolling ball wheel, the turning flexibility of the roller wheel is enhanced; the rolling ball wheel can be applied to apparatuses such as sliding plates, roller skates or wheelchairs, and the steering capacity of and the sliding efficiency of the apparatuses can be effectively improved.

Description

Spin wheel structure-improved

Technical field:

The utility model relates to a kind of roller based on spin, is particularly to a kind of roll mode with the scalar property, improves the spin wheel structure-improved of roller flexibility ratio.

Background technology:

Common roller as shown in Figure 1, be that roller 11 with a tool axis hole is a rolling member, be hubbed at 13 one-tenth one rollers that rotate around fixed rotating shaft of wheel seat through wearing a rotating shaft 12, because the rotation direction that this roller structure tool is fixing, therefore the service direction that need pay special attention to be installed main body on using should be identical with the rotation direction of roller, arbitrarily moving then seems is not suitable for if quilt installing main body needs, as the common slide plate and the roller of tandem wheel, all be to roll in the same direction, therefore and be unfavorable for doing the turning action that differs from this rotating direction, many nondirectional actions, this roller structure just form the resistance in its action, and then the whole speed of sliding of influence.

The utility model content:

Technical problem to be solved in the utility model is: at the deficiencies in the prior art, provide a kind of nothing axle and direction-free spin wheel, to improve the flexibility ratio that turns to of roller, further reduce the spin wheel structure-improved of the consume of power.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of spin wheel structure-improved, comprise a spin, spin is inserted in the hub, hub peripheral hardware one is taken turns cap, spin is confined in the hub, and described hub top convexes with wheel chamber, at least three tops, and each wheel chamber, top is inserted one respectively and can freely be rotated and make spin and hub to keep a spacing and non-touching top wheel in the top wheel is indoor.

The section of wheel chamber, described top is equilateral polygon or is circle.

Compared with prior art, the utility model has the advantages that: take turns direction-free rolling because of spin, improve the turning flexibility ratio of roller by this; And moving direction and ball wheel rotating direction is identical and do not have the consume that reduces power, utilizes this spin wheel can be practiced in equipment such as slide plate, tandem wheel or wheelchairs, can effectively improve the turning efficiency and the slip efficient of above equipment.

The specific embodiment:

At first, please refer to Fig. 2 and shown in Figure 3, this spin is taken turns 2 structures, comprises that a spin 21, a hub 22 and take turns cap 23, and this spin 21 makes and unlikelyly in spin 21 these hubs 22 of limitation deviates from after inserting hub 22 and covering wheel cap 23, wherein:

This spin 21 is a sphere body, is made of the hard abrasion resistant material of matter, can be made into solid or hollow on demand.

This hub 22 encloses the shelly body that is slightly larger than spin 21 for the footpath, these hub 22 top isogonism five equilibriums convex with wheel chamber 221, at least three tops, in it, insert a top wheel 222 respectively, the section of this wheel chamber 221, top can be equilateral polygon or reaches circular, this pushes up wheel 222 undersized can take turns free activity in chamber 221 in this top in pushing up wheel chamber 221, protrude suitable distances to hub 22 inside during these top wheel 222 location, when modern spin 21 is inserted, under the ejection of three top wheels 222, make spin 21 with hub 22 maintenance one spacings and do not contact mutually; Take turns cap 23 with one at last and cover, spin 21 is limited in the hub 22 from these hub 22 open ends, this hub 22 tools one perforate 231, enclose less than the footpath of spin 21 in these perforate 231 apertures, makes spin 21 can be local expose and unlikelyly deviate from by perforate 231.

According to behind the above-mentioned component composition, spin 21 does not only have a part by top wheel 222 supported at three points for 22 li at hub, so can direction-freely roll, improves the turning flexibility ratio of slide plate by this; Add that spin 21 contact points are few, and moving direction and ball wheel rotating direction is identical and do not have the consume that reduces power, further improves the speed of slide plate slides.

Utilize this spin wheel can be practiced in equipment such as slide plate, tandem wheel or wheelchairs, extremely shown in Figure 6 as Fig. 4, through cooperating screw rod 3 integrated structures such as grade, use at least one spin wheel is installed in slide plate 4, tandem wheel 5 the place aheads, or wheelchair 6 chair underfooting sides, can effectively improve the turning efficiency and the slip efficient of above equipment.
