Optionally, the diameter of the smooth section is smaller than that of the thread section.

To sum up, the present application includes the following beneficial effects:

1. the spoke holes are formed in the inner peripheral side of the rim, assembling holes do not need to be formed in the outer peripheral side of the rim, namely, a tire cushion does not need to be added, and the rim is light in weight and high in strength; and can prevent the gas from permeating into the rim and influencing the performance of the rim; the carbon fiber spokes are matched, so that the weight of the wheel set is further reduced, and the strength of the wheel set is improved.

Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The first embodiment is as follows:

referring to fig. 1-8, the present embodiment discloses a bicycle rim structure including a rim 1, spokes 2 and a spoke cap 3 made of aluminum. The spokes 2 are carbon fiber spokes 2. The inner part of the rim 1 is hollow to form a cavity, spoke holes 4 are uniformly formed in the inner peripheral side of the rim 1 at intervals, and air nozzle holes 5 for installing air nozzles are further formed in the rim 1. The diameter of the air nozzle hole 5 is larger than that of the spoke hole 4.

One end of the spoke cap 3 is integrally connected with a clamping portion 31 used for clamping the inner edge of the spoke hole 4, and the diameter of the clamping portion 31 is larger than the diameter of the spoke hole 4 and smaller than the diameter of the air nozzle hole 5. The spoke cap 3 is hollow inside, a threaded section 32 is arranged on the inner wall of one end, close to the clamping portion 31, of the spoke cap, an avoiding section 33 is arranged on the inner wall of one end, far away from the clamping portion 31, of the spoke cap, and the diameter of the avoiding section 33 is larger than that of the threaded section 32. An iron guide pin 6 is connected with the inner thread of the spoke cap 3 and is used for sucking the iron guide pin 6 out of the spoke hole 4 through a magnet. One end of the spoke 2 is fixedly connected in a threaded hole of the spoke cap 3, and the other end of the spoke is connected on a hub of a wheel set.
