Description

Technical Field

[0001] The utility model relates to a bicycle tire with a sealing air nozzle structure, which is applied to the field of bicycle wheel rims. Background Art

[0002] Disc wheel (Disc Wheel or Disc Rotor) in the field of bicycles refers to a specially designed wheel rim, which has a flat, disc-shaped appearance, different from the traditional curved spoke wheel rim. The design of the disc wheel is intended to provide some specific performance advantages, but also has some limitations. Existing bicycle tires usually adopt a vacuum tire structure, that is, the traditional inner tube structure is cancelled. The advantage of this arrangement is that the surface of the vacuum tire is a layer of rubber. After inflation, the surface tension increases, a certain pressure is formed on the inner surface, and the self-sealing ability of the rupture is improved. However, the vacuum tire structure has a higher sealing requirement than the ordinary inner tube structure, and the traditional disc wheel structure has only one tire groove surface. When the air nozzle is installed and limited, the lack of a multi-layer structure for the installation of the air nozzle may result in poor structural stability, resulting in poor air sealing during the installation of the air nozzle, resulting in deflation. Therefore, in response to the above problems, the utility model designs a bicycle tire with a sealed air nozzle structure. Utility Model Content

[0016] As a further improvement, the carcass layer is a rubber sealing layer, and the thickness of the rubber sealing layer is 2 to 3 mm.

[0017] The beneficial effects of the utility model are:

[0018] (1) An inner abutting wall which is recessed toward the axis of the disc wheel body and is disposed on the inner side of the tire groove bottom wall of the disc wheel body, during the installation of the vacuum air nozzle, when the vacuum air nozzle passes through the second mounting hole and the first mounting hole in sequence, the abutting platform abuts against the tire groove bottom wall, the open groove abuts against the bottom of the inner abutting wall, and the nut is threadedly engaged with the external thread so that the nut abuts against the limiting kit, thereby fixing the vacuum air nozzle. Firstly, the arrangement of the inner abutting wall has little effect on the increase in cost and the weight of the material. Secondly, during the installation process, the tire groove bottom wall is used as The first abutment surface and the abutment platform are fixed, and the inner abutment wall serves as the second abutment surface to abut against the opening groove of the limiting kit, and then the nut is used to install and tighten the air nozzle body, thereby limiting the shaking of the vacuum air nozzle, enhancing the stability of the air nozzle installation structure, preventing gas leakage between the vacuum air nozzle and the first installation hole, and strengthening the sealing between the vacuum air nozzle and the disc wheel. In addition, the structure can effectively hide the vacuum air nozzle inside the disc wheel body to prevent the vacuum air nozzle from being exposed during riding, thereby affecting the wind-breaking ability of the wheel rim and thus affecting the driving speed of the bicycle.

[0019] (2) The distance from the inner abutment wall to the bottom wall of the tire groove is approximately 1 / 3 to 1 / 2 of the length of the vacuum air nozzle. Within this range, the consumables of the inner abutment wall can be reduced as much as possible, the manufacturing cost of the disc wheel and the weight of the rim can be reduced, and the installation stability of the vacuum air nozzle can be increased.

[0020] (3) A pair of tire lip clamping walls are symmetrically arranged on the inner side wall of the tire groove, and a tire lip corresponding to the tire lip clamping wall is arranged on the outer side wall of the vacuum tire. The tire lip is clamped and fixed to the tire lip clamping wall, which can effectively limit the left and right directions of the vacuum tire and prevent air leakage caused by displacement of the vacuum tire. A tire lip seat is symmetrically arranged on the bottom wall of the tire groove, and a tire lip accommodating groove is formed between the tire lip seat and the inner side wall of the tire groove. The tire lip is arranged in the tire lip accommodating groove to fix the vacuum tire, which can increase the air tightness of the vacuum tire and prevent air leakage during riding.

Bead seats 114 are symmetrically arranged on the bottom wall of the tire groove 11, and a bead accommodating groove 115 is formed between the bead seat 114 and the inner side wall of the tire groove 11. The bead 31 is arranged in the bead accommodating groove 115 to fix the vacuum tire 30. The vacuum tire 30 is composed of an outer tire layer, a cord layer, and a carcass layer from the outside to the inside, and the carcass layer is a rubber sealing layer. The thickness of the rubber sealing layer is 2 to 3 mm. In this embodiment, the thickness of the rubber sealing layer is 2 mm. The rubber sealing layer can not only increase the strength of the vacuum tire 30, but also slow down the speed of air leakage when the vacuum tire 30 is punctured.

[0034] Reference Figure 3 As shown, the disc wheel body 10 is provided with an inner abutting wall 12 which is recessed toward the axis of the disc wheel body 10 and is located on the inner side of the bottom wall of the tire groove 11, and a first mounting hole 121 is provided on the inner abutting wall 12, and a second mounting hole 111 corresponding to the first mounting hole 121 is provided on the bottom wall of the tire groove 11, and a supporting portion 112 corresponding to the abutting platform 211 is provided at the second mounting hole 111, and the supporting portion 112 can effectively limit the movement of the abutting platform 211 to prevent gas leakage at the second mounting hole 111;
