Description

Technical Field

[0001] This utility model relates to a rim connecting sleeve and a rim. Background Technology

[0002] In the current wheel rim technology field, traditional wheel rim structures are often one-piece designs. While one-piece wheel rims offer certain advantages in structural integrity, the manufacturing process requires the creation of new molds for different sizes and specifications, resulting in higher costs and longer production cycles. Moreover, when a part of the wheel rim is damaged, its integral design often necessitates the replacement of the entire rim, leading to a waste of resources. Utility Model Content

[0003] The main purpose of this utility model is to provide a rim connecting sleeve and a 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 rim connecting sleeve includes an outer support ring, a fixed plate is disposed at the center inside the outer support ring, a plurality of studs are disposed on both sides of the fixed plate along its circumference, an inner limiting ring is disposed on the inner side of the fixed plate, and both ends of the inner limiting ring are disposed on the inner side of the outer support ring.

[0006] Preferably, each side has ten studs, which are evenly distributed on the fixing plate along its circumference.

[0007] Preferably, springs are provided on both sides of the fixing plate between two adjacent studs.

[0008] Preferably, a pressure plate is provided above the spring, and the pressure plate is provided with a through hole for the stud to pass through.

[0009] Preferably, the outer diameter of the pressure plate is the same as the inner diameter of the outer support ring, and the inner diameter of the pressure plate is the same as the outer diameter of the inner limiting ring.

[0010] Preferably, a guide block is vertically provided on the outer side wall of the pressure plate, and a guide groove is provided on the inner wall of the outer support ring to cooperate with the guide block.

[0011] Preferably, four guide blocks are provided, and the four guide blocks are evenly distributed on the outer side wall of the pressure plate along its circumference.

[0012] A wheel rim includes two identical half-rims, which are inserted into and fixed from both ends of a wheel rim connecting sleeve.

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

[0014] The rim connecting sleeve provided by this utility model adopts a split design, which can separate the rim into three independent parts, facilitating local inspection or replacement of damaged parts. Undamaged parts can be reused, effectively avoiding resource waste. By replacing the outer support rings of different lengths, it can quickly adapt to various rim specifications, significantly improving the product's versatility and applicability, and taking into account both economic and functional requirements.

[0022] 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.

[0023] like Figures 1-6 As shown, the rim connecting sleeve provided in this embodiment includes an outer support ring 1, a fixed disk 2 is provided at the center inside the outer support ring 1, a plurality of studs 3 are provided on both sides of the fixed disk 2 along its circumference, an inner limiting ring 4 is provided on the inner side of the fixed disk 2, and both ends of the inner limiting ring 4 are provided on the inner side of the outer support ring 1.

[0024] The rim is split into two structurally desired half-rims 10, each half-rim 10 having a flange.

[0025] When installing onto the tire, insert one half-rim 10 from one side of the outer support ring 1, with the stud 3 passing through the flange on the half-rim 10. The bottom surface of the half-rim 10 abuts against the inner limit ring 4. Then, use a nut to secure the half-rim 10. Place the tire on the outside of the outer support ring 1 with the side of the unconnected half-rim 10 attached. Repeat the above operation to install the other half-rim 10 on the other side of the outer support ring 1. The rims of the two half-rims 10 are respectively engaged on both sides of the tire, completing the installation.

[0026] The rim connecting sleeve makes it easier to align split rims during connection and results in a tighter connection.

[0027] When a wheel rim has a problem, it can be disassembled into three parts. The damaged parts can be inspected, and the undamaged parts can continue to be used, thus avoiding waste of resources.

[0028] By setting outer support rings 1 of different lengths, rims of different specifications can be manufactured, expanding the range of applications.

[0029] In this embodiment, as Figure 5 As shown, ten studs 3 are provided on each side. The ten studs 3 are evenly distributed on the fixing plate 2 along its circumference to ensure the fixing effect.

[0030] In this embodiment, as Figure 3 As shown, springs 5 ​​are provided on both sides of the fixing plate 2 between two adjacent studs 3. The two ends of the springs 5 ​​are fixed to the fixing plate 2 and the pressure plate 6 respectively. When the half rim 10 is installed, the springs 5 ​​will be compressed. The reaction force of the springs 5 ​​helps to prevent the nuts on the bolts from loosening and improves the fixing effect.

[0031] In this embodiment, as Figure 2 and Figure 6 As shown, a pressure plate 6 is provided above the spring 5. The pressure plate 6 has a through hole 7 for the stud 3 to pass through. The bottom surface of the pressure plate 6 is fixed on the spring 5. When the half rim 10 is inserted, it will press down on the pressure plate 6 and the spring 5. When the pressure plate 6 is pressed, the force distribution is more even, so that the spring 5 can be effectively compressed, ensuring the anti-loosening effect. The compressed spring 5 can also absorb a certain amount of vibration and provide a buffering effect.

[0032] In this embodiment, as Figure 2 As shown, the outer diameter of the pressure plate 6 is the same as the inner diameter of the outer support ring 1, and the inner diameter of the pressure plate 6 is the same as the outer diameter of the inner limit ring 4. When installing the half-rim 10, the bottom surface of the half-rim 10 presses the pressure plate 6 into the groove between the outer support ring 1 and the inner limit ring 4 until the bottom surface of the half-rim 10 abuts against the inner limit ring 4, at which point the nut can be used for installation and fixation.

[0033] In this embodiment, as Figure 5 and Figure 6As shown, a guide block 8 is vertically arranged on the outer side wall of the pressure plate 6, and a guide groove 9 is provided on the inner wall of the outer support ring 1 to cooperate with the guide block 8, guide the movement direction of the pressure plate 6, restrict the rotation of the pressure plate 6, and ensure that the pressure plate 6 moves vertically.

[0034] In this embodiment, as Figure 6 As shown, there are four guide blocks 8. The four guide blocks 8 are evenly distributed on the outer wall of the pressure plate 6 and along its circumference, providing more guide points and ensuring the guiding effect.

[0035] A wheel rim includes two identical half-rims 10, which are inserted and fixed from both ends of a wheel rim connecting sleeve.

[0036] In summary, the rim connecting sleeve provided in this embodiment adopts a split design, which can separate the rim into three independent parts, facilitating localized maintenance or replacement of damaged components. Undamaged parts can be reused, effectively avoiding resource waste. By replacing the outer support ring 1 with different lengths, it can quickly adapt to various rim specifications, significantly improving the product's versatility and applicability, while balancing economic and functional requirements.

[0037] 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.
