[0002] Snakebite-like tire blowouts are a common and serious problem during tire use. These blowouts typically occur when driving with low tire pressure, causing significant compression and friction between the tire and the rim, damaging the tire inner tube and ultimately leading to a blowout. Traditional inner tubes have limitations in structure and materials, making them ill-suited to effectively resist this type of damage. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The technical problem to be solved by this utility model is that the inner tubes in the prior art are prone to snake-bite-like tire bursts during use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Please see Figures 1-4 The inner tube shown is a snake-bite-resistant tire blowout resistant inner tube, which includes a ring-shaped tire body 1. The ring-shaped tire body 1 includes a rim contact layer 101, an elastic buffer layer 102 and an airtight layer 103. The elastic buffer layer 102 is disposed between the rim contact layer 101 and the airtight layer 103.

[0030] The rim contact layer 101 is made of ultra-hard butyl rubber with a Shore hardness of 70A. This ultra-hard butyl rubber has high hardness and wear resistance, effectively resisting the compression and friction between the rim and the inner tube, reducing damage to the inner tube. The elastic buffer layer 102 is made of ultra-elastic butyl rubber with a Shore hardness of 50A. Ultra-elastic butyl rubber has good elasticity and cushioning properties, effectively absorbing impact forces during tire operation and protecting the inner tube from damage. The airtight layer 103 is made of butyl rubber with a Shore hardness of 60A. Butyl rubber has excellent airtight properties, effectively preventing tire leakage and ensuring normal tire use.

[0031] One side of the wheel rim contact layer 101 is also provided with a pressure-resistant rib 2. The material of the pressure-resistant rib 2 is the same as that of the wheel rim contact layer 101, which is ultra-hard butyl rubber with a Shore hardness of 70A. Inside the pressure-resistant rib 2, there is also a shear-resistant layer 3, which is made of aramid fiber. Aramid fiber has the characteristics of high strength and high modulus, which can effectively improve the shear resistance of the pressure-resistant rib 2 and further enhance the inner tube's resistance to snake-bite blowouts.

[0032] Multiple pressure-resistant ribs 2 are provided and evenly distributed on the rim contact layer 101, and the pressure-resistant ribs 2 are located in the inner ring layer of the rim contact layer 101 for contact with the rim. Multiple evenly distributed pressure-resistant ribs 2 can more evenly distribute the pressure of the rim on the inner tube, reducing inner tube damage caused by excessive local pressure.

[0033] Each pressure-resistant rib 2 has a height of 1.5-2mm, and the distance between two adjacent pressure-resistant ribs 2 is no more than 10mm. This size design ensures that the pressure-resistant ribs 2 have sufficient compressive strength while reasonably distributing pressure and improving the overall performance of the inner tube.

[0034] The shear-resistant layer 3 is embedded in the compression rib 2 at a depth of not less than 0.3 mm to ensure that the shear-resistant layer 3 can effectively perform its shear-resistant function. The shear-resistant layer 3 is made of aramid fiber using either unidirectional or braided weaving methods and is embedded in the compression rib 2. The thickness of the shear-resistant layer 3 is 0.3-0.5 mm. By rationally selecting the weaving method of the aramid fiber and controlling its thickness, the performance of the shear-resistant layer 3 can be further optimized.

[0035] The outer layer of the rim contact layer 101 is also provided with a self-healing coating 104, which is an epoxidized natural rubber-microencapsulated sulfur modified coating. This self-healing coating 104 can achieve self-repair of the inner tube surface through the release of microencapsulated sulfur and the reaction of epoxidized natural rubber when the tire is slightly damaged, thereby improving the service life of the inner tube.

[0036] The annular tire body 1 is also provided with nozzles 4 for convenient inflation and deflation, and two nozzles 4 are symmetrically arranged on the annular tire body 1. The two symmetrically arranged nozzles 4 can make inflation and deflation operations more convenient, and also help maintain the balance of the inner tube.

[0037] The embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
