[0007] The utility model provides a bicycle rim with reinforcing structure, including outer ring, the inner side of outer ring is fixed with a circle of support ring, the inner side of support ring is equipped with positioning hole, and the fastener is inserted and fixed in positioning hole, the fastener includes the positioning block fixed in positioning hole and the card set sleeve fixed on the outer side of positioning block, and the positioning block and card set sleeve are all hollow structure.

[0008] Further, the support ring is hollow structure, and is the annular structure of outer side big and inner side small, and the section is triangle.

[0009] Further, the positioning block is the circular truncated cone structure of outer side big and inner side small, and the outer side wall of positioning block and the inner side wall of card set sleeve are fixed by the thread structure of being equipped with.

[0010] Further, the inside of card set sleeve is contracted to the middle part, and forms sharp part.

[0011] Further, the fastener and positioning hole are equidistantly provided with multiple groups in support ring. Beneficial effects

[0012] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0013] The utility model utilizes a fastener structure that allows users to securely fasten the fastener to the support ring, which in turn securely connects to the outer ring. The fastener incorporates a combination of a positioning block and a positioning sleeve, providing auxiliary protection when the spokes are fixed to the outer ring. By increasing the contact area between the spokes and the support ring, the structural strength at the spoke root is enhanced, preventing the risk of breakage.

[0014] In this device, the use of a positioning block and a locking sleeve with threaded fastening makes it easy for the user to fix the two at the positioning hole. The spokes pass through the locking sleeve and the positioning block and extend into the support ring. The threaded connection also makes it easy for the user to assemble and disassemble the device.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: A bicycle rim with a reinforced structure, see attached figure. Figure 1 -Appendix Figure 4 The device includes an outer ring 1, and a support ring 2 is fixed on the inner side of the outer ring 1. A positioning hole is opened on the inner side of the support ring 2, and a fastener 3 is inserted and fixed in the positioning hole. The fastener 3 includes a positioning block 31 fixed in the positioning hole and a locking sleeve 32 fixed on the outside of the positioning block 31. Both the positioning block 31 and the locking sleeve 32 are hollow structures.

[0024] The support ring 2 is a hollow structure with a larger outer side and a smaller inner side, forming a triangular ring structure. In this device, the positioning block 31 and the locking sleeve 32 are fixed by threads, which makes it easy for the user to fix them at the positioning hole. The spokes pass through the locking sleeve 32 and the positioning block 31 and extend into the support ring 2. The threaded connection also makes it easy for the user to assemble and disassemble it.

[0025] The positioning block 31 is a frustum structure with a larger outer side and a smaller inner side. The outer wall of the positioning block 31 and the inner wall of the locking sleeve 32 are engaged and fixed by a threaded structure. The inside of the locking sleeve 32 tapers towards the center to form a pointed part. Multiple sets of fasteners 3 and positioning holes are equidistantly arranged inside the support ring 2. Through the structure of the fasteners 3, the user can fix the fasteners to the support ring 2, and then fix the support ring 2 to the outer ring 1. In the fasteners 3, through the combination structure of the positioning block 31 and the positioning sleeve, the fasteners 3 can play an auxiliary protective role when the spokes are fixed to the outer ring 1. By increasing the contact area between the spokes and the support ring 2, the structural strength of the spoke root is improved, avoiding the risk of breakage.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
