Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bicycle rim, more specifically, it relates to a bicycle rim facilitating tire installation. BACKGROUND

[0002] A bicycle is a common means of transportation, which is mainly characterized by portability and environmental protection, and a single bicycle is particularly common.

[0003] A common bicycle uses two wheels as a support structure and moves by controlling the rotation of the wheels. To deal with uneven road conditions, a general wheel is composed of an inner rim and an outer tire. The tire directly contacts the ground and is easily damaged, so it needs to be replaced. To maintain the stability of the tire and the rim, the tire needs to be closely attached to the rim. The surface of the common rim is a concave structure, and the length of the tire cooperates with the inside of the rim. When replacing the tire, the tire needs to be stretched by using a wrench or other tools, so that it can be stretched by tension and then fitted on the rim. The installation operation is laborious and inconvenient. Moreover, when fitting the tire on the rim, a large force is needed to pull one end of the tire. At this time, the part of the tire compared to the stretched part will be pulled in due to the tension, thus moving towards the middle and separating from the edge of the rim, so that the tire cannot maintain an expanded state. It is not convenient to install the tire at each position in the rim, which affects the installation of the tire. In addition, in a common wheel, a large number of support bars are used to connect the center of the rim and the outer hub. A general wheel is simple. These support bars are exposed to the outside. Most bicycles are mainly characterized by low cost and portability. The material of the support bars is also relatively light, and its strength cannot be compared with that of a common bicycle wheel. When subjected to external impact, it is easy to be damaged, resulting in the destruction of the wheel. SUMMARY

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a bicycle rim that facilitates tire installation, and has the following beneficial effects:

[0018] 1. By combining the wheel body, the break point, and the connecting block, the bicycle rim becomes a composite structure. Support and guidance are provided by the cooperation of the support plate, the movable seat, the fixing pin, and the fixing port. When the tire needs to be installed, the fixing pin is released from the fixing port, and the movable seat slides along the support plate. This causes the movable seat to move along the wheel inside the connecting block, exposing the break point. This shortens the circumference of the outer end of the rim, providing space for the tire to be directly fitted onto the wheel body without needing to stretch or bend the tire. Then, the connecting block is reset, and the tire is tightened, completing the tire installation. No wrenches or other tools are needed during this process; installation can be done directly, avoiding excessive tension that could affect the tire. The operation is convenient, time-saving, and labor-saving, making tire installation easy.

[0019] 2. Additional support structure is provided by the support column. When installing the tire, first put the tire on the support column at one end of the wheel body to spread the tire open. The anti-slip capability is enhanced by the anti-slip threads, which further stabilizes the tire. When the tire is pulled onto the wheel body, the tire is under force and the two ends contract inward. The two ends are supported by the support column, so that the tire is always in an open state. This makes it easy to place the tire on the wheel body and avoids the tire being pulled too far in the direction of installation due to the contraction of the two ends, which could cause the installed tire part to detach. This makes the tire installation stable and convenient.

[0020] 3. The protective shell provides a protective structure. It is installed in conjunction with the support column through the mounting holes and the anti-slip threads through the fixing nuts. The protective shell is pressed and fixed to both ends of the wheel body, which shields and protects the support bar, support plate and moving seat structure inside the wheel, preventing external influences on the inside of the wheel. The protective shell is independently designed and can be directly replaced after being damaged, which is more economical than replacing the wheel. Attached Figure Description
