CN2794896Y - Inflation-free tire with arc convex in inner ring - Google Patents

Abstract

The utility model relates to an inflation-free tire with an arc-shaped clamping convex in an inner ring. One circular ring-shaped inflation-free tire is composed of an outer tire body (1), a spongy body (2), the arc-shaped clamping convex (3), and a clamping edge (4), wherein the outer tire body (1) is wrapped at the outer surface of the spongy body (2); the clamping edge (4) is directly arranged on both sides of the middle lower part of the outer tire body (1); the arc-shaped clamping convex (3) is arranged on the lowermost part of the outer tire body (1), namely the inner ring of the tire. The utility model has the advantages of favorable wear resistance, good elasticity and no inflation; the utility model overcomes the defects that the tire needs to be inflated and the air leaks when the tire is pricked in the prior art.

Description

Ring has the protruding non-inflatable tyre of arc card in a kind of

Affiliated technical field

The utility model belongs to a kind of novel inflation-free tire, the protruding a kind of non-inflatable tyre of ring arc card in especially relating to.

Background technology

Tires such as existing commercially available bicycle, battery-driven car, motor bike are traditional air-inflation tyre basically, promptly inflate the back by the inner tube of a tyre and support cover tire, because inflation is afraid of that then thorn is lost heart or disappointing flat tire, riding to people makes troubles; In addition, in the existing patent for example the patent No. be though that 03263632.6 non-inflatable tyre is also exempted from gas filed novel designs, but what adopt is to reach with the method that is filled in outer tyre cavity after the waste rubber grain bonding to exempt from gas filed purpose, poor flexibility and very difficult that waste rubber grain even filling in tire is full is not so result of use is very desirable.

Summary of the invention

In order to overcome some deficiency of existing tire and existing non-inflatable tyre, but a kind of novel inflation-free tire that high elasticity sponge shape and protected tyre slide that is evenly distributed, has in inside tires is provided, thereby drawbacks such as the inner tube of a tyre that solves tire is afraid of to prick, the flat tire that loses heart.

The scheme that its technical matters that solves the utility model adopts is: one, with outer carcass (1) and cavernous body (2) processed respectively: adopt the foaming puffing technique inside tires to be transformed into a kind of little air chamber of little closed pore on the one hand, form a kind of rubber-like, distribution well-proportioned foam sponge body (2), make tire have elasticity and cushion effect preferably, the outer carcass (1) that does not foam in the outer setting of cavernous body (2) on the other hand is with this wearing layer that contacts with ground as tire and play increase tire wear and intensity; Its three, be provided with a kind ofly by the some one positive one circular-arc arc card protruding (3) of bonded assembly that instead and mutually coincide in the inboard of tire, to increase the end friction drag of spoke steel strand in steel ring, slide to reduce.

The beneficial effects of the utility model are: because with rubber pange, make it to form the springiness formed by the stingy chamber of countless little closed pores and the cavernous body of cushion effect, thereby need not inflate, be not afraid of the bundle tire, can not blow out, it is tired to have exempted labor, the tire patching of inflating, and changes the cost of the inner tube of a tyre because of breaking tire, brings many facilities to the bicyclist; Simultaneously, the arc card is protruding to have prevented the slip of tire in steel ring again owing to be provided with, and makes product have more reliability.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the utility model sectional structure chart.

Fig. 2 is the utility model cross-sectional structure figure.

1. outer carcasses among the figure, 2. cavernous body, 3. protruding, the 4. edge of arc card.

The specific embodiment

In Fig. 1, outer carcass (1) is one the certain thickness wear-resisting outside periderm layer that does not foam to be arranged; The internal package of outer carcass (1) cavernous body (2); The both sides, bottom of carcass (1) are provided with outwardly directed edge (4) outside; (3) be that the arc card is protruding, the bottom that is arranged on outer carcass (1) equably is on the interior ring of tire, block protruding and card protruding between distance at interval suitably.

Claims (2)

1, a kind of interior ring has the protruding non-inflatable tyre of arc card, it by outer carcass (1), cavernous body (2), curve card protruding (3) edges (4), form, it is characterized in that: carcass outside one deck (1) in the outer wrap of cavernous body (2), the both sides, middle and lower part of carcass (1) are provided with edge (4) outside, outside the bottom of carcass (1) be tire in be equipped with arc card protruding (3).

2, a kind of interior ring according to claim 1 has the protruding non-inflatable tyre of arc card, it is characterized in that: arc card protruding (3) is arranged at the inboard of tire and encircles circumference promptly, this arc card is protruding to be made up of the some one anti-one bonded assembly convex structure that just and mutually coincide, and the setting of equalization.
