AI Technical Summary

Technical Problem

If the spoke nuts on a bicycle rim are not aligned with the spoke installation direction, it can cause the spokes to shift, break, or loosen, affecting riding safety and increasing maintenance difficulty. In addition, the thick inner wall of the rim makes it less lightweight.

Method used

A spoke hole base ring is provided in the wheel rim body. The spoke hole base ring includes a ring belt and multiple spoke hole bases. The spoke hole bases are perpendicular to the axis of the spokes. The spoke nuts are coaxially assembled with the spokes to ensure that the spoke nuts and spokes are on the same axis and to avoid misalignment and loosening.

Benefits of technology

It improves the installation stability of the spokes, reduces the risk of spoke breakage and loosening, lowers the maintenance frequency, enhances riding safety, and makes the rim lighter and thinner.

Abstract

The bicycle rim with the spoke hole base ring comprises a rim body, the spoke hole base ring, spoke nuts and spokes, an annular closed cavity is formed in the rim body, and the spoke hole base ring is arranged on the bottom wall, corresponding to the radial inner side of the closed cavity, of the rim body. The spoke hole base ring comprises a ring belt and a plurality of spoke hole bases arranged on the ring belt, spoke holes are formed in the spoke hole bases, the tooth cap ends of the spokes penetrate through the spoke holes to be coaxially assembled with the spoke nuts, the surfaces of the spoke hole bases are perpendicular to the axis direction of the spokes, and the spoke holes are formed in the spoke hole bases. The installation direction of the spoke nut is the same as the installation direction of the spoke, one side of the spoke can be prevented from deviating and making contact with the spoke nut to form a break angle so as to be broken, meanwhile, the other side of the spoke is prevented from being not in contact with the spoke nut to be loosened, the tension of the spoke is prevented from being reduced, and the spoke is more worry-saving and durable. And meanwhile, the riding safety of a user is improved, and the requirement for light weight of the rim is met.
