Description

Technical Field

[0001] The utility model relates to the technical field of bicycle parts, and particularly relates to a combined bicycle rim. Background Art

[0002] The bicycle rim is one of the main components of the bicycle wheel, and is usually made of materials such as steel, aluminum or carbon fiber. It is a key part that bears the weight and impact force during bicycle riding, and needs to have high strength, durability and stability. The bicycle rim is usually composed of spokes, rims and axles, and can be designed and customized according to different types of bicycles and uses.

[0003] The conventional bicycle rims have the following disadvantages: 1. The part in contact with the brake pads is integrally arranged, which is easy to wear after long-term use, affecting the overall strength of the rim. Therefore, when it is worn, the whole rim needs to be replaced. For this reason, we propose a combined bicycle rim. Summary of the Invention

[0004] The main purpose of the utility model is to provide a combined bicycle rim, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A combined bicycle rim, comprising a rim body, a partition board and a wear-resistant sheet. A groove is opened on the outer wall of the rim body, and the wear-resistant sheet is arranged in the groove. Countersunk screws are opened at the outer side of the wear-resistant sheet near the top and the bottom, and countersunk screw holes are arranged in the countersunk screws. The wear-resistant sheet and the rim body are tightly connected through the countersunk screw holes and the countersunk screws. The wear-resistant sheet is made of tungsten steel material.

[0007] Furthermore, annular stoppers are welded at one ends near the top and the bottom of the wear-resistant sheet, which is convenient for effectively limiting the brake pads and improving the stability when the brake pads are in contact with the wear-resistant sheet.

[0008] Furthermore, a partition board is arranged between the inner walls of the rim body. Through the partition board, when a tire is clamped and installed in the rim body, a closed space is formed between the partition board and the tire.

[0009] Furthermore, a reserved hole is penetrated through the inner side of the rim body.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The utility model relates to a combined bicycle rim. By loosening the countersunk screws, personnel can conveniently replace the wear-resistant pieces. When the head of the countersunk screw is close to being exposed from the countersunk screw hole, it indicates that the wear-resistant piece is severely worn, and it can be used as a wear mark to prompt the wear degree at the contact part with the brake pad. This bicycle rim is of a split type, and the part in contact with the brake pad can be disassembled separately, eliminating the need to replace the entire rim when the contact part wears, thus reducing resource waste.

[0016] To make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the following further elaborates the utility model in conjunction with specific embodiments.

[0017] As Figures 1-3 shown, a combined bicycle rim includes a rim body 1, a partition board 8 and a wear-resistant piece 5. A groove 2 is provided on the outer wall of the rim body 1, and the wear-resistant piece 5 is arranged in the groove 2. Countersunk screws 4 are provided near the top and bottom of the outer side of the wear-resistant piece 5, and countersunk screw holes 3 are arranged in the countersunk screws 4. The wear-resistant piece 5 and the rim body 1 are firmly connected through the countersunk screw holes 3 and the countersunk screws 4. The wear-resistant piece 5 is made of tungsten steel material.

[0018] Among them, annular stops 6 are welded near one end of the top and bottom of the wear-resistant piece 5.

[0019] In this embodiment, as Figures 1-3 shown, the annular stops 6 facilitate the effective limitation of the brake pad, improving the stability when the brake pad contacts the wear-resistant piece 5.

[0020] Among them, a partition board 8 is arranged between the inner walls of the rim body 1.

[0021] In this embodiment, as Figure 1As shown, through the partition plate 8, when the tire is clamped and installed inside the rim body 1, a closed space is formed between the partition plate 8 and the tire.

[0022] Wherein, a reserved hole 7 is formed through the inner side of the rim body 1.

[0023] In this embodiment, as Figure 1 shown, the reserved hole 7 facilitates the pre-embedding of the threaded sleeve block, and the threaded sleeve block is used to facilitate the installation of the spokes of the bicycle.

[0024] It should be noted that the present utility model is a combined bicycle rim. During operation, through the cooperation of the countersunk screw hole 3 and the countersunk screw 4, the wear-resistant sheet 5 is conveniently fixed in the groove 2. The annular stop block 6 facilitates the effective limitation of the brake pad, improving the stability when the brake pad contacts the wear-resistant sheet 5. The wear-resistant sheet 5 made of tungsten steel material has good wear resistance and can effectively improve the service life. Personnel can conveniently replace the wear-resistant sheet 5 by loosening the countersunk screw 4. And when the head of the countersunk screw 4 is close to being exposed from the countersunk screw hole 3, it indicates that the wear-resistant sheet 5 is severely worn and can be used as a wear mark to prompt the wear degree of the contact part with the brake pad. This bicycle rim is of a split type, and the part in contact with the brake pad can be disassembled separately, without the need to replace the whole rim when the contact part is worn, reducing resource waste.

[0025] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the description in the specification only illustrate the principles of the present utility model.
