Description

Technical Field

[0001] The utility model relates to the field of bicycle parts, in particular to a spoke hole plug. Background Art

[0002] Common bicycle sizes now include 12 / 14 / 16 / 18 / 20 / 22 / 24 / 26 / 27.5 / 29 inches / 700C road bikes. 70% of the wheels they use are non-tubeless wheels. Non-tubeless wheels are composed of spokes, rims, and hubs. Non-tubeless wheels now use tire pads to solve the problem of inner tube protection.

[0003] The inside of the rims on non-tubeless wheels are designed with holes, the purpose of which is to facilitate maintenance and installation of spokes. This structure has continued to this day. The disadvantage of having holes on the inside of the rims is that once the inner and outer tubes are installed, if the tire pad is not installed, the inner tube will be inflated and will directly contact the rim holes, causing the inner tube to be damaged and unusable. Therefore, tire pads have been used to solve the inner tube protection problem. If the tire pad is used with non-tubeless rims, the defect is that if the tire pad is too thin or the material is not good, the inner tube will be damaged once it is inflated to 70PSI or above, especially now that lightweight is pursued. Ultra-thin inner tubes have been popular in recent years. Even after the tire pad is installed, once the inner tube exceeds the 70PSI air pressure, it will still cause the inner tube to bulge or be damaged. The inner tube protection cannot be completely solved. If the tire pad is made too thick, the weight will increase a lot, which is not in line with the current lightweight riding style, and the comfort will also be reduced. Utility Model Content

[0004] The purpose of the utility model is to provide a spoke hole plug in order to solve the above problems.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model discloses a spoke hole plug, comprising a protective plug body, wherein the protective plug body comprises a conical support platform and an elliptical support block, the conical support platform is fixedly connected to the elliptical support block, and a fixing hole is opened at the bottom of the conical support platform.

[0007] As a preferred technical solution of the spoke hole plug of the utility model, the conical support platform and the elliptical support block are both made of silicone material.

[0008] As an optimal technical solution for the spoke hole plug of the utility model, the conical support platform is in the shape of a cone that is wide at the top and narrow at the bottom. The diameter of the circle on the top surface of the conical support platform is 9.8 mm, the diameter of the circle on the bottom surface of the conical support platform is 7 mm, and the height of the conical support platform is 12 mm.

[0009] As a preferred technical solution of the spoke hole plug of the utility model, the length of the elliptical support block is 15.8 mm and the width is 9.8 mm.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model is made of silicone material, which is moderately soft and hard, light in weight, and fits well with the inner tube without causing surface damage to the inner tube. The diameter of the top surface circle of the conical support platform is 9.8mm, and the diameter of the bottom circle is 7mm, which is compatible with all the spoke holes of the rims on the market. An elliptical support block is designed on the top of the conical support platform. The elliptical support block can prevent the protective plug body from sinking into the spoke hole of the rim due to high pressure, and can resist high pressure and force. The elliptical support block is easy to take and convenient for future maintenance of the spokes. After the spoke hole plug is used on a non-vacuum wheel set, the inner tube can be directly installed for use, which forms a good protection for the inner tube, and the inner tube can be used repeatedly without bulging or being scratched by the rim mouth. The spoke hole plug can also be used in conjunction with a tire pad, which can not only solve the problem of high pressure resistance, but also make the inner side of the entire rim smooth, forming sufficient protection for the inner tube.

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] In the drawings, the same reference numerals all refer to the same components.

[0019] Example 1

[0020] like Figure 1-3As shown, it includes a protective plug body 1, which includes a conical support platform 2 and an elliptical support block 3. The conical support platform 2 is fixedly connected to the elliptical support block 3, and a fixing hole 4 is opened at the bottom of the conical support platform 2.

[0021] Furthermore, the conical support platform 2 and the elliptical support block 3 are both made of silicone material.

[0022] The conical support platform 2 is in the shape of a cone that is wide at the top and narrow at the bottom. The diameter of the circle on the top surface of the conical support platform 2 is 9.8 mm, the diameter of the circle on the bottom surface of the conical support platform 2 is 7 mm, and the height of the conical support platform 2 is 12 mm.

[0023] The length of the elliptical support block 3 is 15.8 mm and the width is 9.8 mm.

[0024] Specifically, the conical support platform 2 and the elliptical support block 3 are made of silicone material, which is moderately soft and hard, light in weight, and fits well with the inner tube without causing surface damage to the inner tube. The diameter of the top surface circle of the conical support platform is 9.8mm, and the diameter of the bottom circle is 7mm, which is compatible with all the spoke holes of the rims on the market. An elliptical support block is designed on the top of the conical support platform. The elliptical support block can prevent the protective plug body from sinking into the spoke hole of the rim due to high pressure, and can resist high pressure and force. The elliptical support block is easy to take and convenient for future maintenance of the spokes. The spoke holes of non-vacuum wheels are used After plugging, the inner tube can be directly installed for use, which provides better protection for the inner tube and allows the inner tube to be used repeatedly without bulging or being scratched by the rim opening. The spoke hole plugs can also be used in conjunction with tire pads, which not only solves the problem of high pressure resistance, but also makes the inner side of the entire rim smooth, providing sufficient protection for the inner tube. The fixing holes 4 are set to ensure that the conical support platform 2 has flexible contraction performance. After the conical support platform 2 is plugged into the smaller spoke hole of the rim, the conical support platform 2 can contract to adapt to the spoke hole of the rim, making it convenient for the conical support platform 2 to be inserted into the spoke hole of the rim and reducing the overall weight.

[0025] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
