Abstract

The utility model discloses a kind of polyurethane rubber-covered wheel, polyurethane cover tire including outsourcing and the plastic insert by two half pairing welding, plastic insert includes inner rim, spoke, wheel rim circle, outer rim and two joint flash sides, outer rim is arranged on the neighboring of wheel rim circle, and joint flash side is the outstanding convex featheredge ring extended to from the side arc of outer rim above the outer surface of outer rim；Wherein, inner rim, spoke, wheel rim circle, outer rim are hollow-core construction；Outer rim and joint flash side are embedded in polyurethane cover tire and are integrated into using foam process completely；It the advantage is that：1st, two half are made up of same pair of mould, save die cost, are easy to weld job；By foam process, hollow outer rim is enclosed with polyurethane cover tire, can so mitigate tire overall weight；3rd, two joint flash sides are provided with, the shock deformation in outside and three directions of outer surface in tire can be born, strengthen polyurethane cover tire ability of anti-deformation and elasticity.

Description

A kind of polyurethane rubber-covered wheel

Technical field

It the utility model is related to the wheel used on a kind of perambulator；Specifically a kind of polyurethane rubber-covered wheel.

Background technology

The wheel used in perambulator and the wheel requirement used in automobile are different, because its needs undertakes heavy burden and speed Will slowly, but this tire not represented in perambulator is not required to intensity and elasticity, because perambulator is also required to traveling rugged Road surface, can also collide stone or step.

Other perambulator is that children use, and is ensureing some strength and elasticity, and increase children ride in the case of comfort level, Wheel is more light better.

Utility model content

The utility model is in view of the shortcomings of the prior art, provide a kind of polyurethane rubber-covered in light weight, that the good elasticity of intensity is high Wheel.

In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of polyurethane bag Rubber tire includes the polyurethane cover tire of outsourcing and the plastic insert by two half pairing welding, and the plastic insert includes lubrication groove Circle, spoke, wheel rim circle, outer rim and two joint flash sides, pass through wheel several described between the inner rim and the wheel rim circle Spoke is connected, and the outer rim is arranged on the neighboring of the wheel rim circle, and the joint flash side is to prolong from the side arc of outer rim Reach the outstanding convex featheredge ring above the outer surface of outer rim；Wherein, inner rim, spoke, wheel rim circle, outer rim are hollow knot Structure；Outer rim and joint flash side are embedded in the polyurethane cover tire and are integrated into using foam process completely.

On the outer rim, circumferentially to being evenly equipped with several axially through open tubular columns；Two joint flash sides are mutual not Contact；On joint flash side, several through holes are circumferentially evenly equipped with.

Several spoke reinforcements are provided with each spoke, are extended outwardly to the outside inner surface of wheel rim circle；In foreign steamer In circle, circumference extends inwardly to the inner side inner surface of wheel rim circle to several outer rim reinforcements are evenly equipped with.

The inner surface of the inner rim is evenly equipped with several hollow projections, and the dome of the hollow projection is provided with projection Bar.

The utility model compared with prior art, has the advantages that：1st, two half are made up of same pair of mould, Die cost is saved, is easy to weld job；2nd, by foam process, hollow outer rim is enclosed with polyurethane cover tire, so Tire overall weight can be mitigated；3rd, two joint flash sides are provided with, outside and three directions of outer surface in tire can be born Deformation is hit, strengthens polyurethane cover tire ability of anti-deformation and elasticity, increase children ride comfort level, 4, open tubular column and through hole Polyurethane can be embedded in foaming process so that polyurethane cover tire firmly installs, and adhesive force is stronger.

Brief description of the drawings

Fig. 1 is the integrally-built structural representation of the utility model embodiment.

Fig. 2 is the polyurethane cover tire of the utility model embodiment and the part explosive view of plastic insert.

Fig. 3 is the plastic insert and its profile of the utility model embodiment.

Fig. 4 is the structural representation of the half of the utility model embodiment.

Embodiment

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：As Figure 1-4, mark Note is as follows：It is polyurethane cover tire 1, half 2, plastic insert 3, inner rim 4, spoke 5, wheel rim circle 6, outer rim 7, joint flash side 8, hollow Post 9, through hole 10, spoke reinforcement 11, outer rim reinforcement 12, hollow projection 13, raised item 14.

A kind of polyurethane rubber-covered wheel includes the polyurethane cover tire 1 of outsourcing and the plastic insert by two pairing of half 2 welding 3, two half are the same, it is possible to reduce number of molds, plastic insert include inner rim 4, spoke 5, wheel rim circle 6, outer rim 7 and two Individual joint flash side 8, connected between inner rim and wheel rim circle by three spokes, outer rim is arranged on the neighboring of wheel rim circle, is flown Wing side is the outstanding convex featheredge ring extended to from the side arc of outer rim above the outer surface of outer rim；Wherein, inner rim, wheel Spoke, wheel rim circle, outer rim are hollow-core construction；Outer rim and joint flash side are embedded in polyurethane cover tire and using foaming works completely Skill is integrated into, and the main purpose of this structure is the usage amount for reducing polyurethane, reduces cost；Mitigate overall weight, Because children's is physical limited.

In order to increase the sound construction degree of product, two spoke reinforcements 11 are provided with each spoke, extend outwardly to The outside inner surface of wheel rim circle；In outer rim, circumference extends inwardly to wheel rim circle to nine outer rim reinforcements 12 are evenly equipped with Inner side inner surface, the quantity of outer rim reinforcement needs to change according to tire specification.

In order to increase the attachment dynamics of polyurethane cover tire and plastic insert, and offset external force；On outer rim, along circle The through open tubular column 9 in 18 axial directions circumferentially is evenly equipped with, the quantity of open tubular column needs to change according to tire specification；Two joint flash sides It is not in contact with each other, can also contacts and weld；On joint flash side, multiple through holes 10 are circumferentially evenly equipped with.

Because of the needs of assembling, the inner surface of inner rim is evenly equipped with three hollow projections 13, and the dome of hollow projection is set There is raised item 14.
