Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of solid tires, and more particularly to a solid bicycle tire. Background Technology
[0002] Solid bicycle tires, also known as tubeless tires, are tire structures without an inner tube, made of rubber or other materials molded as a single piece.
[0003] Many existing shared bicycles use solid tires; this design reduces the frequency of leaks and repairs, but it also means that a large number of solid tires need to be disposed of when the bicycles are scrapped. The reuse value of used solid tires is relatively low, and the processing is complex and costly; however, if they are not properly disposed of and are simply discarded, they will pollute the environment. Utility Model Content
[0004] The purpose of this utility model is to provide a solid bicycle tire to solve the aforementioned technical problems.
[0005] Utility model solution:
[0006] This utility model provides a solid bicycle tire, including a solid inner tube and an outer tire; the solid inner tube is made from a waste solid tire, and its cross-sectional shape is processed into a circle and placed inside the outer tire; the outer tire is used to be installed on the wheel hub.
[0007] Furthermore, the solid inner tube is formed by cutting the outer circumference of a waste solid tire using a round bar mill.
[0008] Furthermore, the solid inner tube has a rough outer surface formed by cutting.
[0009] Furthermore, the inner wall of the solid inner tube has deformation grooves to increase deformation during use.
[0010] Furthermore, when the outer tire is installed on the wheel hub, the solid inner tube is in contact with the outer tire.
[0011] Furthermore, the outer tire includes an integrally formed mounting portion and a fitting portion; the mounting portion is used to mount onto the wheel hub; the fitting portion is fitted onto the solid inner tube.
[0012] Furthermore, the inner wall of the solid inner tube and the mounting portions on both sides form a buffer cavity.
[0013] Beneficial effects:
[0014] This utility model provides a solid bicycle tire, wherein a new combined tire structure is formed by reprocessing a discarded shared bicycle solid tire and directly installing it inside the outer tire. This not only realizes the reuse of waste materials, but also simplifies the processing process and reduces costs. In addition, the solid inner tube is a regular circle, which facilitates the processing of the outer circumference of the discarded solid tire. Furthermore, the solid inner tube only needs to be directly fitted inside the outer tire, and during installation, only the outer tire needs to be installed on the rim, making installation relatively convenient.

[0026] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0027] This embodiment provides a solid bicycle tire; please refer to... Figure 1-3 As shown, it includes a solid inner tube 10 and an outer tire 20; the solid inner tube 10 is made from a waste solid tire, and its cross-sectional shape is processed into a circle and placed inside the outer tire 20; the outer tire 20 is used to be installed on the wheel hub 30.
[0028] Specifically, the solid inner tube 10 is a regular circle, which makes it easy to process the outer circumference of the waste solid tire. At the same time, the solid inner tube 10 only needs to be directly fitted inside the outer tire 20, and during installation, the outer tire 20 only needs to be installed on the rim 30, which is relatively convenient.
[0029] In this embodiment, the solid inner tube 10 is formed by cutting the outer periphery of a waste solid tire using a round bar machine.
[0030] Specifically, before cutting with a round bar mill, the waste solid tires can be cut into pieces. It is best to glue multiple solid tires together end to end. Then, a solid tire segment, similar to a long rope, is placed into the limiting wheel of the round bar mill for cutting. Therefore, the solid inner tube 10 formed after processing and gluing has at least one adhesive surface. It should be noted that since solid tires are not as hard as wooden sticks but have a certain degree of elasticity, limiting tubes need to be installed at the inlet and outlet of the round bar mill near the cutter to limit the solid tire during cutting, thereby reducing its shaking and ensuring the cutting effect of the outer periphery.
[0031] In this embodiment, the solid inner tube 10 has a rough outer surface formed by cutting.
[0032] Specifically, the roughness of the outer surface formed by this cutting is quite obvious, and it can play a good role in friction limiting when fitted inside the outer tire 20.
[0033] In this embodiment, the inner ring wall of the solid inner tube 10 has a deformation groove 11, which is used to increase the deformation during use.
[0034] Specifically, the two walls of the deformation groove 11 can undergo large elastic deformation when subjected to deformation force, thus narrowing or expanding relatively, thereby increasing the degree of deformation that the solid inner tube 10 can adapt to. In addition, the deformation groove 11 can be a strip groove. At the same time, since the solid inner tube 10 mainly undergoes radial or circumferential elastic deformation within its own circumferential space, the deformation groove 11 can be extended along the axial direction or in a direction close to the axial direction.
[0035] In this embodiment, when the outer tire 20 is installed on the wheel hub 30, the solid inner tube 10 is in contact with the outer tire 20.
[0036] Specifically, when the two mounting portions 21 of the outer tire 20 are subjected to force and narrow to a near-mounted state or are directly mounted on the rim 30, the fitting portion 22 of the outer tire 20 can fit and wrap around the solid inner tire 10.
[0037] In this embodiment, the outer tire 20 includes an integrally formed mounting part 21 and a fitting part 22; the mounting part 21 is used to mount the wheel hub 30; the fitting part 22 is fitted onto the solid inner tube 10.
[0038] Specifically, the structure and principle of the mounting part 21 and the wheel hub 30 are subject to existing technology and will not be elaborated here.
[0039] In this embodiment, the inner ring wall of the solid inner tube 10 and the two sides of the mounting portion 21 form a buffer cavity 40.
[0040] Specifically, after the outer tire 20 is installed on the rim 30, the buffer cavity 40 is located between the inner wall of the solid inner tube 10, the two side mounting parts 21 and the outer peripheral wall of the rim 30, which can play a good role in buffering and shock absorption when riding.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
