Description

A kind of baby carriage tires

[technical field]

The utility model relates to perambulator, especially a kind of baby carriage tires.

[background technology]

The material that the tire of current perambulator, waggon, toy car generally adopts has EVA foaming, PU, rubber etc.Wherein, EVA foaming tire is due to low cost, and structure is simple, and quality is light, be widely used, but the wear-resisting and non-skid property of EVA foaming tire is relatively poor without the need to inflation.Wearing no resistance of tire, mean tire used quick abrasion, the life-span is short; For general perambulator, the non-skid property difference then means safe decline of its tire, and being constantly worn along with tire, non-skid property can decline further, thus threatens use and the safety performance thereof of car load.

For this reason, mainly contain for the wear-resisting of EVA foaming tire and the poor improvement opportunity method of non-skid property:

1, in EVA expanded material, increase the additive of wear-resisting on-slip;

2, the density of EVA foaming tire is increased;

3, corresponding rubber peel is designed to wrap up EVA foaming tire;

4, rubber peel bonded or be coated to EVA foaming tire surface.

For said method, first, the additive that adds wear-resisting on-slip in EVA expanded material can the overall performance improving tire, but at the occasion still Shortcomings of some high request; The second, the density increasing EVA foaming tire can make cost increase, and brings difficulty to manufacture; Although three, the corresponding rubber peel of design can increase substantially the performance of tire separately, cost is too expensive, is unfavorable for enterprise development; Four, directly to fit rubber peel at the outside face of EVA foaming tire, its assembly difficulty is high, quality disunity, and effect is bad, after use is of a specified duration or frequently turn to, easily comes off.

Namely the utility model is researched and proposed for the deficiencies in the prior art.

[utility model content]

The technical problems to be solved in the utility model is to provide a kind of baby carriage tires, the tire body be made up of EVA expanded material is provided with annular groove, the wear-resisting ring be made up of rubber-plastics material with antiwear characteristic is adopted then to be embedded in annular groove, structure is simple, low cost of manufacture to adopt the pushchair of this structure to have, and wear-resisting and that non-skid property is excellent feature.

For solving the problems of the technologies described above, a kind of baby carriage tires of the utility model, comprise the tire body be made up of EVA expanded material and the wear-resisting ring be made up of the rubber-plastics material with antiwear characteristic, be circumferentially provided with annular groove outside described tire body, described wear-resisting ring is embedded on annular groove.

Described wear-resisting ring is made up of rubber or TPR or PU material.

Described wear-resisting ring is formed in one and is circular ring structure.

Described wear-resisting ring is elastic circular ring structure.

Be convex globoidal bottom described annular groove, described wear-resisting ring medial surface is cancave cambered surface.

Or described annular groove is rectangular recess, V-type groove or U-type groove.

The thickness of described wear-resisting ring is A, and the degree of depth of described annular groove is B, meets: A >=B.

The width of described wear-resisting ring is E, and the width of described tire body is F, meets: 1/2F >=E >=1/3F.

Compared with prior art, a kind of baby carriage tires of the utility model, tool has the following advantages:

1, tire body still adopts EVA expanded material, has low cost of manufacture, and quality is light, without the need to the feature of inflation; And wear-resisting ring adopts the rubber-plastics material with antiwear characteristic, and be embedded in the annular groove on tire body, increased substantially the wear-resisting of tire and non-skid property, and then improved the safety performance of perambulator, meanwhile, ease of assembly, reduces manufacturing cost.

2. wear-resisting ring is formed in one and unremitting elastic circular ring structure, by itself flexible tensional fixation in the annular groove of tire body, has simple structure, manufactures, assembles simple feature.

[detailed description of the invention]

Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.

As depicted in figs. 1 and 2, a kind of baby carriage tires of the utility model, comprise the tire body 1 be made up of EVA expanded material, and the wear-resisting ring 2 that the rubber-plastics material having antiwear characteristic by rubber, TPR or PU etc. is made, circumferentially be provided with annular groove 3 outside described tire body 1, described wear-resisting ring 2 is embedded on annular groove 3.Because tire body 1 adopts EVA expanded material to make, tire is made still to have the feature that quality is light and cost is low, and wear-resisting ring 2 is embedded on annular groove 3, improve the wear-resisting of tire and non-skid property, ensure to adopt the perambulator of this tire, waggon and toy car to have use safety, durable feature.

Described wear-resisting ring 2 is formed in one and in circular ring structure, wear-resisting ring 2 can be connected by interference fit and annular groove 3.

Described wear-resisting ring 2 is elastic circular ring structure, and wear-resisting ring 2 can be embedded in annular groove 3 securely by the elasticity tension of self.In order to make wear-resisting ring 2 firmly be connected with annular groove 3, can also between wear-resisting ring 2 medial surface to annular groove 3 bottom surface, apply corresponding adhesive agent and be fixedly connected with.

In order to ensure that wear-resisting ring 2 is connected reliably with annular groove 3 further, be convex globoidal bottom described annular groove 3, described wear-resisting ring 2 medial surface is cancave cambered surface, and namely the cancave cambered surface of wear-resisting ring 2 and the convex globoidal of annular groove 3 fit tightly.

In addition, according to design needs, described annular groove 3 can also be rectangular recess, V-type groove or U-type groove etc., and the inner shape of described wear-resisting ring 2 is then corresponding to match with rectangular recess, V-type groove or U-type groove etc.

The thickness of wear-resisting ring 2 described in the utility model is A, and the degree of depth of described annular groove 3 is B, meets: A >=B.According to the operating needs of varying environment, A, B can adopt different numerical value, when this wheel is common use, as shown in Figure 3 and Figure 5, can adopt A=B; When this wheel need regular for turning to flexibly time, as shown in Figure 4 and Figure 6, then adopt A > B.

The width of described wear-resisting ring 2 is E, and the width of described tire body 1 is F, and in order to reach both wear-resisting and non-skid property requirements, save manufacturing cost again, the utility model is preferred: 1/2F >=E >=1/3F.

And in particular cases, be then not limited to above-mentioned relation according to the shape of actual tire body 1; Namely when wear-resisting ring 2 is mounted in annular groove 3 completely, and during A=B, the width E of wear-resisting ring 2 is then slightly wider.

In sum, the utility model has simply, low cost of manufacture, and wear-resisting and that non-skid property is excellent feature.
