Description

Inflation-free tyre Technical Field The utility model relates to the technical field of tires, in particular to a inflation-free tire. Background The tyre is a ring-shaped elastic rubber product which is assembled on various vehicles or machines and rolls in a grounding way, is usually arranged on a metal rim, can support a vehicle body and buffer external impact, realizes contact with a road surface and ensures the running performance of the vehicle, is usually used under complex and severe conditions, and has high bearing performance, traction performance and buffer performance due to various deformation, load, force and high and low temperature effects during running, and in the prior art, the bicycle is required to be used in actual use, and the bicycle tyre is required to be inflated frequently in actual use, and the tyre body is wear-resistant and poor in puncture-preventing performance, so that the service life of the bicycle tyre is influenced. Disclosure of utility model The utility model aims to overcome the technical defects, and provides a inflation-free tire, which solves the technical problems that the bicycle tire in the prior art needs to be inflated, has poor puncture-proof and explosion-proof effects in the actual use process, and influences the service life of the bicycle tire. In order to achieve the technical purpose, the utility model adopts the following technical scheme: In a first aspect, the present utility model provides a inflation-free tire comprising: The tire comprises an outer tire body, wherein the outer tire body is provided with a tire lip end; the tire bead seat is provided with a protruding end, the protruding end is close to the tire bead seat, the tire bead seat is also provided with a recessed end, the outer tire body is assembled with the tire bead seat, a filling cavity is formed, a polyurethane foaming adhesive layer is arranged in the filling cavity, and a protective layer is arranged on the outer wall of the outer tire body. In some embodiments, the bead end includes a first bead and a second bead for extending into the recessed end. In some embodiments, the raised ends comprise a first and a second raised, the first and second raised being disposed on either side of the bead seat and being configured to position the first and second beads with a recessed end disposed therebetween. In some embodiments, the recessed end includes a first recessed channel having a first bead disposed therein, a second recessed channel having a second bead disposed therein, and a third recessed channel. In some embodiments, the protective layer comprises a reinforcing layer, a shock absorbing layer and a tread wear layer, wherein the reinforcing layer, the shock absorbing layer and the tread wear layer are sequentially arranged on the outer tire body from bottom to top, and the reinforcing layer is a steel wire harness belt material layer. In some embodiments, the shock-absorbing layer comprises a neoprene layer and a styrene-butadiene rubber layer, a shock-absorbing ball is arranged on the neoprene layer, and a buffer groove matched with the styrene-butadiene rubber layer is formed in one surface of the styrene-butadiene rubber layer, which faces the shock-absorbing ball. In some embodiments, the tread wear layer is a polypropylene mesh belt filler layer, the outer surface of which is provided with wear patterns.
