Description

Technical Field

[0001] This utility model relates to a firmly connected split wheel rim. Background Technology

[0002] In traditional wheel rim design and use, split rims, with their unique structural features and application scenarios, occupy a certain position in wheel assembly in specific fields. A typical split rim usually consists of two halves, and the installation process usually involves first installing one half of the rim on one side of the tire, then installing the other half on the other side, and finally securing the two halves together with bolts or other connectors. However, in actual installation, this step-by-step installation method, due to the lack of a precise positioning mechanism, often results in the mounting holes on the two halves of the rim not aligning perfectly, affecting the bolt connection and leading to a less secure connection. Utility Model Content

[0003] The main objective of this invention is to provide a firmly connected split wheel rim to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved by adopting the following technical solution:

[0005] A firmly connected split wheel rim includes a lower wheel rim and an upper wheel rim. An extension ring is provided on the outer side of the lower wheel rim, and a guide groove is provided on the inner wall of the extension ring along its height direction. A guide strip is provided on the outer wall of the upper wheel rim, and the outer wall of the upper wheel rim is inserted into the extension ring.

[0006] Preferably, the top of the extension ring abuts against the bottom edge of the upper rim.

[0007] Preferably, a lower flange is provided on the inner side of the extension ring on the lower rim, and an upper flange is provided at the bottom end of the upper rim.

[0008] Preferably, a plurality of studs are provided at circumferential intervals on the top surface of the lower flange, and a through hole is provided on the upper flange for the studs to pass through.

[0009] Preferably, each of the studs is disposed between two adjacent flange holes on the lower flange.

[0010] Preferably, the inner ring edge of the lower flange has a wavy structure, and the bottom surface of the inner ring of the upper flange is provided with a wavy insert plate, which meshes with the inner ring of the lower flange.

[0011] Preferably, four guide grooves are provided, and the four guide grooves are evenly distributed on the inner wall of the extension ring and along its circumference.

[0012] Preferably, a sealing ring is provided in the gap between the extension ring, the lower flange and the upper flange, and the sealing ring is fixedly connected to the extension ring and the lower flange.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] 1. This utility model features an extension ring on the outer side of the lower rim. After the lower rim is installed on one side of the tire, the end face of the extension ring extends to the other side of the tire. The upper rim achieves precise alignment through the cooperation of the guide strip and the guide groove, ensuring that the flange holes of the lower flange and the upper flange are precisely aligned, facilitating the smooth passage and fixing of bolts. Simultaneously, it restricts the insertion direction of the upper rim, ensuring it always moves vertically and guaranteeing more precise alignment.

[0015] 2. This utility model improves the fixing effect by setting an upward-facing stud on the lower flange and using a downward insertion method when installing bolts, so that the fixing direction of the bolts and studs is opposite.

[0016] 3. This utility model provides a wavy structure on the inner edge of the lower flange and a wavy insert plate on the bottom surface of the upper flange, so that the two mesh with each other, effectively preventing the bolts from loosening due to relative rotation between the lower and upper rims, and enhancing the firmness and reliability of the connection.

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-6 As shown, the firmly connected split rim provided in this embodiment includes a lower rim 1 and an upper rim 2. An extension ring 3 is provided on the outer side of the lower rim 1, and a guide groove 4 is provided on the inner wall of the extension ring 3 along its height direction. A guide strip 5 is provided on the outer wall of the upper rim 2, and the outer wall of the upper rim 2 is inserted into the extension ring 3.

[0026] After the lower rim 1 is installed on one side of the tire, the end face of the extension ring 3 can extend to the other side of the tire. The upper rim 2 achieves precise docking through the cooperation of the guide strip 5 and the guide groove 4, so that the flange holes of the lower flange 6 and the upper flange 7 are precisely aligned, making it easy for the bolts to pass through and be fixed.

[0027] In this embodiment, as Figure 4 As shown, the top of the extension ring 3 abuts against the bottom edge of the upper rim 2, ensuring that the end face of the extension ring 3 can reach the other side of the tire during installation, making it easy to align the upper rim 2.

[0028] In this embodiment, as Figure 5 As shown, a lower flange 6 is provided on the inner side of the extension ring 3 on the lower rim 1, and an upper flange 7 is provided at the bottom end of the upper rim 2 for the fixed connection between the lower rim 1 and the upper rim 2.

[0029] In this embodiment, as Figure 5 and Figure 6 As shown, multiple studs 8 are spaced circumferentially on the top surface of the lower flange 6, and through holes 9 are provided on the upper flange 7 for the studs 8 to pass through. The studs 8 are oriented upwards. When installing bolts, a downward insertion method is adopted, so that the fixing direction of the bolts and studs is opposite, forming a double fixing connection with opposite directions, providing connection strength.

[0030] In this embodiment, as Figure 1 As shown, each stud 8 is positioned between two adjacent flange holes on the lower flange 6 to avoid interference with the flange holes and improve connection stability.

[0031] In this embodiment, as Figure 5 and Figure 6 As shown, the inner ring edge of the lower flange 6 has a wavy structure, and the bottom surface of the inner ring of the upper flange 7 is provided with a wavy insert plate 10. The wavy insert plate 10 and the inner ring of the lower flange 6 mesh with each other to form a mechanical interlock, which effectively prevents the upper rim 2 and the lower rim 1 from rotating relative to each other.

[0032] In this embodiment, as Figure 5As shown, four guide grooves 4 are provided. The four guide grooves 4 are evenly distributed on the inner wall of the extension ring 3 and along its circumference, which improves the guiding accuracy and ensures the accurate alignment of the upper wheel rim 2 and the lower wheel rim 1, avoiding tilting or offset.

[0033] In this embodiment, as Figure 4 As shown, a sealing ring 11 is provided in the gap between the extension ring 3, the lower flange 6 and the upper flange 7. The sealing ring 11 is fixedly connected to the extension ring 3 and the lower flange 6. During the installation process, the upper rim 2 gradually squeezes the sealing ring 11 downward, so that the sealing ring 11 fills the gap between the extension ring 3, the lower flange 6 and the upper flange 7, thereby improving the sealing performance of the rim and preventing air leakage.

[0034] In summary, in this embodiment, by setting an extension ring 3 on the outer side of the lower rim 1, after the lower rim 1 is installed on one side of the tire, the end face of the extension ring 3 can extend to the other side of the tire. The upper rim 2 achieves precise docking through the cooperation of the guide strip 5 and the guide groove 4, ensuring that the flange holes of the lower flange 6 and the upper flange 7 are precisely aligned, facilitating the smooth passage and fixing of bolts. Simultaneously, it restricts the insertion direction of the upper rim 2, ensuring that it always moves vertically, guaranteeing more precise docking.

[0035] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
