Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bicycle parts, in particular to a spoke cap with high toughness and anti-deformation. Background Art
[0002] Spoke wheels are often used in bicycles. Spoke wheels mainly include a hub, a rim, and spokes connecting the hub and the rim. The spoke wheels can absorb shocks and achieve lightness through deformation of the rim and spokes, and can adjust themselves when encountering obstacles.
[0003] The spoke wheels currently on the market all have mounting holes directly on the rim, and then the spokes are sealed and installed through spoke caps. There are always some gaps at the joints between the spokes and the spoke caps, which cause water vapor to enter and damage the spokes and the spoke caps. In addition, the existing spoke caps are not strong enough and are easily deformed or directly damaged by the external environment, resulting in a short service life. Utility Model Content
[0004] The main purpose of the utility model is to provide a high-toughness anti-deformation spoke cap through a sealant and an air bag. When the spoke pierces the air bag, the sealant flows to the inside of the cap body, and then when connected with the spoke, a better seal can be performed. By arranging a reinforcing block and a hardened ring, the overall strength of the spoke cap is greatly enhanced, making it less likely to deform.
[0005] In order to solve the above technical problems, the utility model discloses a high-toughness and anti-deformation spoke cap, comprising: a cap body, a top of the cap body is provided with a limiting rib extending to both sides, the cap body is provided with a downwardly opening mounting groove, the top of the mounting groove is provided with an air bag, and the air bag is provided with a sealant; the cap body is provided with a reinforcing block which gradually decreases from upward to downward to the present, two groups of limiting grooves are provided on the upper side of the reinforcing block, a hardened ring is provided in the limiting groove, the hardened ring protrudes from the reinforcing block, and an anti-rust layer is provided on the outer side of the reinforcing block, the hardened ring and the limiting rib are provided with a rust-proof layer; a sealing gasket is arranged at the bottom of the cap body.
[0006] According to an embodiment of the utility model, the airbag is bonded to the top of the installation groove.
[0007] According to an embodiment of the utility model, the cap body, the limiting retaining edge and the reinforcing block are integrally formed.
[0008] According to one embodiment of the utility model, the thickness of the anti-rust layer is 2-3 μm.
[0009] Compared with the prior art, the present application can obtain the following technical effects:
[0010] 1) Through the sealant and the airbag, when the spoke pierces the airbag, the sealant flows to the inside of the cap body, and then when it is connected with the spoke, it can be better sealed. By setting the reinforcement block and the hardened ring, the overall strength of the spoke cap is greatly enhanced, making it not easy to deform.
[0011] Of course, any product implementing the present utility model does not necessarily need to achieve all of the above technical effects at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0017] Please refer to Figure 1 , Figure 1 It is a cross-sectional view of a high-toughness anti-deformation spoke nipple of an embodiment of the present application. As shown in the figure, a high-toughness anti-deformation spoke nipple comprises: a cap body 10, a limiting rib 20 extending to both sides is provided on the top of the cap body 10, a downwardly opening mounting groove 30 is provided on the cap body 10, an air bag 40 is provided at the top of the mounting groove 30, and a sealant 50 is provided in the air bag 40; a reinforcing block 60 with a diameter gradually decreasing from top to bottom is provided around the cap body 10, two groups of limiting grooves 61 are provided on the upper side of the reinforcing block 60, a hardened circular ring 70 is provided in the limiting groove 61, the hardened circular ring 70 protrudes from the reinforcing block 60, and an anti-rust layer 80 is provided on the outer side of the reinforcing block 60, the hardened circular ring 70 and the limiting rib 20; a sealing gasket 90 is provided at the bottom of the cap body 10.
[0018] In the embodiment of the utility model, a limiting retaining edge 20 extending to both sides is provided on the top of the cap body 10 to facilitate the work of workers. A downwardly opening mounting groove 30 is provided on the cap body 10, and an airbag 40 is provided at the top of the mounting groove 30. The airbag 40 is bonded to the top of the mounting groove 30, and a sealant 50 is provided in the airbag 40. When the spoke pierces the airbag 40, the sealant 50 flows to the inside of the cap body 10, and then when connected with the spoke, better sealing can be performed to prevent water vapor from entering the connection between the spoke and the spoke cap.
[0019] Furthermore, reinforcing blocks 60 are provided around the cap body 10 and gradually decrease from upward to downward. The cap body 10, the limiting rib 20 and the reinforcing block 60 are integrally formed. Two sets of limiting grooves 61 are provided on the upper side of the reinforcing block 60. A hardened ring 70 is provided in the limiting groove 61. By arranging the reinforcing block 60 and the hardened ring 70, the overall strength of the spoke cap is greatly enhanced, making it less likely to deform.
[0020] Furthermore, an anti-rust layer 80 is provided on the outer sides of the reinforcing block 60 , the hardened ring 70 and the limiting retaining edge 20 . The thickness of the anti-rust layer 80 is 2-3 μm, which further enhances the overall anti-rust capability of the cap body 10 and increases its service life.
[0021] Furthermore, a sealing gasket 90 is provided at the bottom of the cap body 10 to enhance the sealing performance between the cap body 10 and the rim.
[0022] The above description shows and describes several preferred embodiments of the present application, but as before, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the present application through the above teachings or the technology or knowledge of the relevant field.
