Description

Technical Field

[0001] This utility model relates to the field of bicycle tire technology, and in particular to a bicycle tire that is easy to install. Background Technology

[0002] With the development of science and technology and the progress of the times, all kinds of bicycles have entered people's daily lives. Bicycle tires are an important component of bicycles, which not only affect the comfort of riding, but also directly affect the performance and safety of bicycles. Bicycle tires are divided into inner tires and outer tires.

[0003] In the existing bicycle inner tube installation process, the valve is first inserted into the through hole at the rim, and then the inner tube is slowly placed into the pre-installed outer tire along the edge of the rim. However, after the inner tire is pulled by different forces, the last part of the inner tire is often placed into the outer tire in a state that is too tight or too loose, thus affecting the installation effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing bicycle inner tires. During installation, the valve is first inserted into the through hole at the rim, and then the inner tire is slowly placed into the pre-installed outer tire along the edge of the rim. However, after the inner tire is pulled by different forces, the last part of the inner tire is often placed into the outer tire in a state that is too tight or too loose, thus affecting the installation effect. Therefore, this invention proposes a bicycle tire that is easier to install.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bicycle tire that is easy to install, comprising:

[0007] The tire body has a reserved groove on its inner wall, and a fixing piece is glued to the inner side of the reserved groove. An air valve is connected to the side of the fixing piece facing the center of the tire body. The surface of the tire body is coated with scale lines, and a limiting piece is glued to the surface of the tire body. A threaded post is connected to the internal thread of the limiting piece, and a positioning post is fixed at the top of the threaded post.

[0008] Preferably, the limiting piece has an arc-shaped structure and is fitted to the outer wall of the wheel hub.

[0009] Preferably, the positioning post is symmetrical about the central axis of the tire body, and the positioning post and the limiting piece are arranged perpendicularly.

[0010] Preferably, the scale lines are integrated with the tire body through coating to form an integral structure.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting the limiting piece, positioning post, scale line and tire body, people can insert the valve and positioning post into the through hole at the wheel hub to form a three-point positioning mode. Then, by manually comparing the scale line with the markings on the surface of the outer tire, the corresponding force is applied to place and push the inner tire. This ensures that when the last part of the inner tire is placed, it will not be too tight or too loose when it enters the outer tire, thus resulting in excellent installation effect of the inner tire.

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1-3 A convenient bicycle tire includes a tire body 1. The inner wall of the tire body 1 has a reserved groove 6, and a fixing piece 5 is glued to the inner side of the reserved groove 6. An air valve 2 is connected to the side of the fixing piece 5 facing the center of the tire body 1. The connection structure between the air valve 2 and the fixing piece 5 is a conventional technology, so it will not be described in detail. The surface of the tire body 1 is coated with scale lines 8, and a limiting piece 3 is glued to the surface of the tire body 1. The scale lines 8 form an integrated structure with the tire body 1 through the coating. The inner tire is installed and pushed by the operator according to the comparison between the scale lines 8 and the markings on the surface of the outer tire. This ensures that when the last part of the inner tire is installed, it will not be too tight or too loose when it enters the outer tire.

[0020] The limiting piece 3 has an internal threaded connection to a threaded post 7, and a positioning post 4 is fixed to the top of the threaded post 7. The limiting piece 3 has an arc-shaped structure and fits against the outer wall of the wheel hub. The outer wall of the wheel hub has a groove that matches the limiting piece 3, which facilitates the placement of the limiting piece 3. The outer wall of the wheel hub also has a through hole that matches the positioning post 4, which facilitates the placement of the positioning post 4. The positioning post 4 is symmetrical about the central axis of the tire body 1 and is perpendicular to the limiting piece 3. People can insert the valve 2 and the positioning post 4 into the through hole at the wheel hub to form a three-point positioning mode, which facilitates the installation of the inner tire.

[0021] Working principle: In use, the staff first inserts the valve 2 and the positioning pin 4 into the through hole at the wheel hub to form a three-point positioning mode. Then, the staff pushes the tire body 1 along the edge of the wheel hub into the outer tire. At the same time, the staff compares the scale line 8 with the markings on the surface of the outer tire and applies the appropriate force to place and push the inner tire. This ensures that when the last part of the inner tire is placed, it will not be too tight or too loose when it enters the outer tire. Finally, the installation of the inner tire of the bicycle is completed.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
