Therefore, they cannot be understood as limiting the specific protection scope of the utility model.

[0031] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".
[0032] Please also read Figures 1 to 5 The two-piece wheel connection structure provided by the utility model is now described. The two-piece wheel connection structure includes a rim 10, a spoke 20 and a rivet 30. The inner circumference of the rim 10 is provided with a convex strip 11 extending in a spiral path. The convex strip 11 has a plurality of connecting rings 12. Each connecting ring 12 is provided with a first through hole 13 axially penetrating the rim 10. The first through holes 13 on each connecting ring 12 of the adjacent chain correspond to each other. The outer circumference of the spoke 20 is provided with at least one matching ring 21. The matching ring 21 is used to be screwed between two adjacent connecting rings 12. The matching ring 21 is provided with a second through hole 22 axially penetrating the spoke 20. The rivet 30 is matched with the corresponding first through hole 13 and second through hole 22 to fix the matching ring 21 between two adjacent connecting rings 12.
[0033] Optionally, the number of turns of the connecting ring 12 is 1.5 to 3. If the number of connecting rings 12 is too large, it is not convenient to screw in the matching ring 21, and the length of the rivet 30 to be installed will be too long, increasing the cost; the number of connecting rings 12 in this embodiment can ensure that the matching ring 21 is screwed in and facilitate the installation of the rivet 30.
[0034] Compared with the prior art, the two-piece wheel connection structure provided in this embodiment has the following advantages: when assembling the rim 10 and the spoke 20, the spoke 20 is screwed into the rim 10, the width of the matching ring 21 is the same as the width of the connecting ring 12, the matching ring 21 is screwed between two adjacent connecting rings 12 in a similar way to thread matching, the positions of the first through hole 13 and the second through hole 22 are adjusted to correspond, and then the rivet 30 is installed. The two-piece wheel connection structure of the utility model adopts the rivet 30 for connection, the rivet 30 is not easy to fall off, the connection is more stable, and the service life is longer; the matching ring 21 on the spoke 20 is between two adjacent circles of connecting rings 12 on the rim 10, which enhances the connection strength between the rim 10 and the spoke 20, improves the shear and bending resistance, and can withstand greater load force; the rotation direction of the matching ring 21 between the connecting rings 12 is consistent with the rotation direction of the wheel, ensuring that the connection is more stable during the driving of the wheel and is not easy to loosen due to the driving of the wheel. The above-mentioned method can enhance the connection strength between the spoke 20 and the rim 10, reduce the degree of friction and wear, effectively protect the wheel, and improve product safety.
[0035] In some embodiments, a specific implementation of the above-mentioned first through hole 13 and second through hole 22 can adopt the structure described below, which is not shown in the figure. The first through hole 13 and the second through hole 22 are each provided with two, and the two first through holes 13 are symmetrically distributed with the radial direction of the rim 10 as the axis of symmetry, and the two second through holes 22 are symmetrically distributed with the radial direction of the spoke 20 as the axis of symmetry.
[0036] As a modified embodiment of the first through hole 13 and the second through hole 22, see Figure 1 to Figure 2 , Figures 4 to 5 There are multiple first through holes 13 and multiple second through holes 22 , and the multiple first through holes 13 are evenly distributed around the axial direction of the rim 10 , and the multiple second through holes 22 are evenly distributed around the axial direction of the spoke 20 .
[0037] For the above two arrangements, if it is necessary to facilitate installation and ensure connection stability, two first through holes 13 and second through holes 22 can be provided. The two first through holes 13 are relatively distributed, which can ensure that the arrangement position of the rivet 30 passes through the axis of the wheel, and the connection stability is guaranteed; if it is necessary to further enhance safety, multiple first through holes 13 (for example, 6 to 10) can be provided around the axis of the rim 10, so that the connection is more secure, and the first through holes 13 are evenly distributed to avoid excessive noise during driving. The second through holes 22 are the same.
[0038] In some embodiments, a specific relationship between the rivets 30 and the first through holes 13 and the second through holes 22 may adopt the following structure: the number of rivets 30 is equal to the number of second through holes 22, or the number of rivets 30 is less than the number of second through holes 22. When the number of first through holes 13 is greater than the number of second through holes 22, and the number of second through holes 22 is large, the number of rivets 30 can be selected according to the actual installation requirements. When installing, it is not necessary to install rivets 30 in each second through hole 22, that is, the number of second through holes 22 is greater than the number of rivets 30, and the connection strength is ensured, and the assembly is more flexible; when the number of second through holes 22 is small, it is necessary to install rivets 30 in each second through hole 22, that is, the number of second through holes 22 is equal to the number of rivets 30.
[0039] In some embodiments, an improved embodiment of the rivet 30 can be implemented as follows: Figure 3 See the structure shown. Figure 3 Both ends of the rivet 30 have a clamping portion 31, and the two clamping portions 31 respectively abut against the opposite sides of two adjacent circles of connecting rings 12. When installing the blind rivet 30, the rivet core needs to be pulled out so that two clamping portions 31 are formed at both ends of the rivet body, and the two clamping portions 31 respectively abut against the opposite sides of two adjacent circles of connecting rings 12, which can cause the two connecting rings 12 to produce a certain degree of deformation, thereby clamping the matching ring 21, and the connection is tightened to prevent the matching ring 21 from shaking between the two circles of connecting rings 12.
[0040] In some embodiments, an improved implementation of the above-mentioned matching ring 21 can be adopted as follows Figure 4 See the structure shown. Figure 4 The matching ring 21 has multiple turns, two adjacent turns of the matching ring 21 are connected end to end, and the multiple turns of the matching ring 21 extend in a spiral route. The number of turns of the matching ring 21 is less than or equal to the number of turns of the connecting ring 12. When the number of matching rings 21 is large, the matching area between the connecting ring 12 is increased, and the connection strength is higher.
[0041] Specifically, the thickness of the matching ring 21 is less than or equal to the spacing between two adjacent circles of connecting rings 12. When the thickness of the matching ring 21 is less than the spacing between two adjacent circles of connecting rings 12, it is convenient to screw in, but there is a gap after assembly, which is easy to shake and affects the driving experience; when the thickness of the matching ring 21 is equal to the spacing between two adjacent circles of connecting rings 12, the rivet 30 is more stable after screwing in, reducing noise.
[0042] In some embodiments, an improved implementation of the above two-piece wheel connection structure can be adopted as follows Figure 3 See the structure shown. Figure 3 The two-piece wheel connection structure further includes a fixing sleeve 40 , which passes through the first through hole 13 and the second through hole 22 corresponding to the upper and lower parts in sequence, and the rivet 30 passes through the fixing sleeve 40 .
[0043] Optionally, the fixed sleeve 40 is a steel sleeve. After the matching ring 21 is screwed into two adjacent connecting rings 12, the steel sleeve is pressed in by a steel sleeve machine to ensure interference fit between the steel sleeve and the first through hole 13 and the second through hole 22. Subsequently, the rivet 30 is installed in the steel sleeve to ensure that the two are firmly connected, not prone to relative rotation, and strong in friction and wear.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
