CN2794893Y - Foamed inflation-free tire with concave groove at two sides - Google Patents

Abstract

The utility model relates to a foamed inflation-free tire with concave grooves at both sides. One circular ring-shaped inflation-free tire is composed of an outer tire body (1), a spongy body (2), a clamping convex (3), a clamping edge (4) and grooves (5), 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 clamping convex (3) is arranged at the lowermost part of the outer tire body (1), and the lowermost part of the outer tire body (1) is namely an inner ring of the tire; the grooves (5) are arranged on both sides of the middle part of the outer tire body. 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 inflation and the air leaks when the tire is pricked in the prior art.

Description

The fluted foaming non-inflatable tyre in a kind of both sides

Affiliated technical field

The utility model belongs to a kind of novel tire, especially relates to the non-inflatable tyre of foaming in a kind of tire.

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, rides to people and bring inconvenience.

Summary of the invention

In order to overcome some deficiency of existing tire, provide a kind of and be spongy and lightweight novel inflation-free tire, thereby solve drawbacks such as tire inner tube is afraid of to prick, the flat tire that loses heart in inside tires.

The scheme that its technical matters that solves the utility model adopts is: one, with outer carcass (1) and cavernous body (2) difference processed, 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 cavernous body (2), make tire have elasticity and cushion effect preferably, on the other hand in the outer setting of cavernous body (2) do not foam outside carcass (1), with this wearing layer that contacts with ground as tire and play increase tire wear and intensity; Its three, the both sides of carcass have been designed groove (5) and have not only been alleviated quality but also have certain buffer action outside; Its four, be provided with card protruding (4) in the inboard of tire, increase and the end friction drag of spoke steel strand in steel ring with this, slide to reduce.

The beneficial effects of the utility model are: because with rubber or polyurethane foam, 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.
