Abstract

The utility model provides a safe tyre structure which consists of an outer tyre body and an inner tyre ring body. The outer tyre body is provided with a blocking part and a containing part. The containing part is used for containing the inner tyre ring body which is a ring body made from elastic material, therefore, the inner tyre ring body can not be punctured and cause the danger of tyre burst. The manufacturing procedure of mass production is simple and can reduce the cost; furthermore, the safe tyre structure is universal for the ordinary traditional tyre, so as to achieve the efficacies of high safety, good using convenience and low manufacturing cost.

Description

The safety tyre structure

Technical field

The utility model relates to a kind of safety tyre structure, refers to a kind of high security and economic benefit tire that is applied to carrier especially.

Technical background

By at present known tire construction as shown in Figure 6, it is made of outer carcass 20 and interior carcass 30, and carcass 30 is to be located in its outer carcass 20 in it, and carcass 30 is provided with valve portion 31 in it, this valve portion 31 is for pouring into gas to interior carcass 30, and so it has the following point existence:

1, poor stability: when this tire is located on the carrier, as travel on road surface chance sharp object puncture, carcass produces to break promptly to be commonly called as and blows out in then making, and causes the unsettled danger peace factor of travelling, so its poor stability.

2, ease of use is poor: when outside, during the damage of inner tube of a tyre puncture property, must change immediately or keep in repair, and the formality of its replacing and the maintenance inner tube of a tyre is loaded down with trivial details and not easy to operate, so its ease of use is poor.

And for example shown in Figure 7 is another known state reference map of tire construction, and it lies in and is integrally formed with rubber or foamed plastic layer 23 within the outer carcass 20, makes this tire form a band tyre, but it has following problem existence:

1, the manufacturing cost height: it lies in outer carcass inside and is integrally formed with rubber or foamed plastic layer, and forming band tyre, and that it fills up outer carcass inside material requested amount is many, forms the lifting of whole cost, so its manufacturing cost height.

2, ease of use is poor: because its outer carcass inside is integrally formed with rubber or foamed plastic layer, its one piece tyre weight is increased the weight of, when changing of tire or other need remove a tyre maintenances, cause the constant of operation, so its ease of use is poor.

The utility model for improving known tire construction poor stability, ease of use difference and the high problem of manufacturing cost, is to finish safety tyre structure of the present utility model in view of the above problems.

Summary of the invention

Main purpose of the present utility model is to provide a kind of safety tyre structure, it is made of outer carcass and inner tube of a tyre ring body, its outer carcass is provided with fastening part and holding part, its holding part is for inserting inner tube of a tyre ring body, and the section of its inner tube of a tyre ring body is rounded, and its inner tube of a tyre ring body is that rubber-like silica gel or EVA (Ethylene-Vinyl Acetate) foam are made, so inner tube of a tyre ring body can not cause the danger of blowing out because of puncture, but the simple and easy and cost-cutting of its quantity-produced processing procedure, it can be common to general conventional tire in addition, and is safe to reach, the effect of the good and low cost of manufacture of ease of use.

Advantage of the present utility model is as follows: safe: because of the ring body that its inner tube of a tyre system is a tool elasticity, need not worry to produce when being punctured and blow out, and cause the danger of travelling, so it is safe.Convenience height: during its tire sharp object puncture, can be with the row that travels to the safe place again to handle, need not be got rid of immediately, so its ease of use height.Save use cost: during its tire sharp object puncture, the sharp object that only needs to be punctured is pulled out, and need not impose tire patching or changing of tire, so it can effectively save use cost.

For further specifying structure of the present utility model, feature and other purposes, now with as after preferred embodiment attached with graphic detailed description, the illustrated embodiment of this legend is the usefulness for explanation, is not the restriction to the present patent application protection domain.

The specific embodiment

Consult Fig. 1, shown in 2, be the solid combination and the decomposing state scheme drawing of the utility model safety tyre structure, it comprises: an inner tube of a tyre ring body 10, this inner tube of a tyre ring body 10 is the elastic bodys that are high supportive structure, that this elastic system is is solid, fine pore or macropore state, and the section of this inner tube of a tyre ring body 10 is rounded, and this inner tube of a tyre ring body 10 is made for silica gel or EVA foam; One outer carcass 20, this outer carcass 20 is provided with fastening part 21 and holding part 22, and its holding part 22 supplies to insert inner tube of a tyre ring body 10, and its fastening part 21 supplies to combine closely tire framework 40, and its inner tube of a tyre ring body 10 is to be to separate setting (consulting Fig. 4) with outer carcass 20.

As shown in Figure 3, the profile status scheme drawing of the utility model safety tyre structure, its outer carcass 20 is provided with fastening part 21 and holding part 22, its holding part 22 is for inserting inner tube of a tyre ring body 10, and its inner tube of a tyre ring body 10 is made for elastomeric silica gel of tool or EVA foam, it can also form by waste material adhesive tape sintering in addition, its inner tube of a tyre ring body 10 can not cause the danger of blowing out because of puncture, but the simple and easy and cost-cutting of its quantity-produced processing procedure, in addition it can be common to general conventional tire, and is safe to reach, ease of use is good and the effect of low cost of manufacture.

As shown in Figure 4, it is the running condition reference diagram of the utility model safety tyre structure, when outer carcass 20 runs on the road surface and is subjected to sharp object 50 puncture, when sharp object 50 punctures to interior carcass 10, because of carcass in it 10 is solid, fine pore or macropore state elastic body, thus need not worry the danger of blowing out and travelling, and need not to be handled immediately, can wait to travel it to be pulled out to the safe place gets final product again, and has effectively increased safety, the convenience that uses and has saved whole cost.

As shown in Figure 5, it is another embodiment reference diagram of the utility model safety tyre structure, it is with this inside and outside

carcass

10,20, combine with the tire framework 40 of locomotive or bicycle use, also can reach and prevent the effect of blowing out, effectively increased safety, the convenience that uses and saved whole cost, to increase another practicality of the present utility model.
