Both ends of the sleeve screw 24 are threadedly connected to the first threaded hole 2211 and the second threaded hole 211 respectively.

[0058] In this application, if Figure 4 As shown, the surrounding wall 222 includes a straight section 2221 and an opening section 2222 that are interconnected. The straight section 2221 and the opening section 2222 are both annular structures. The straight section 2221 is connected to the main body 221, and the opening section 2222 is connected to the end of the straight section 2221 that is away from the main body 221. The inner diameter of the opening section 2222 is larger than the inner diameter of the straight section 2221, that is, the distance between the inner wall of the opening section 2222 and the central axis of the connecting sleeve 22 is larger than the distance between the inner wall of the straight section 2221 and the central axis of the connecting sleeve 22. Therefore, it is easier for the connecting member 21 to enter the surrounding wall 222, making it easier for the connecting sleeve 22 to be sleeved on the connecting member 21.

[0059] Further, a third threaded hole 2212 is provided on the end surface of the main body 221 facing the locking member 23, and the locking member 23 is threadedly connected to the third threaded hole 2212. It can be understood that a threaded section is provided at one end of the locking member 23, and one end of the locking member 23 can be connected to the connecting sleeve 22 through the third threaded hole 2212 after passing through the fixed end 41. It can be understood that the main body 221 of the present application has a first threaded hole 2211 at one end and a third threaded hole 2212 at the other end, and the first threaded hole 2211 and the third threaded hole 2212 are not connected.

[0060] In some embodiments, the locking member 23 includes a rod body 231 and a screwing portion 232 connected to one end of the rod body 231 away from the connecting sleeve 22. A through hole 411 is opened on the fixed end 41. The rod body 231 is inserted into the through hole 411. The radial dimension of the screwing portion 232 is larger than the radial dimension of the rod body 231. The screwing portion 232 abuts against the fixed end 41. The provision of the screwing portion 232 can facilitate the user to screw the locking member 23, making locking more labor-saving.

[0061] It should be noted that the locking member 23 of the present application can be a split structure, that is, the rod body 231 and the screwing portion 232 are mutually buckled and fixed, which is convenient for replacement. The locking member 23 of the present application can also be an integrally formed structure, so as to ensure the structural strength of the locking member 23. Optionally, the locking member 23 of the present application is a fastening screw.

[0062] In some embodiments, the fixed end 41 also includes a resisting portion 412 extending from the hole wall of the through hole 411 toward the axis of the through hole 411, and an elastic member 25 is sleeved on the rod body 231, one end of the elastic member 25 abuts against the resisting portion 412, and the other end of the elastic member 25 abuts against the end surface of the screwing portion 232 facing the fixed end 41, and the elastic member 25 is compressed between the resisting portion 412 and the end surface of the screwing portion 232 facing the fixed end 41, so when the locking member 23 is loosened, the elastic member 25 will bounce the locking member 23 away, thereby improving the disassembly efficiency.

[0063] Optionally, the elastic member 25 of the present application is a spring. Of course, in other possible implementations, the elastic member 25 may also be rubber, etc., as long as it has elastic restoring force, and the present application does not limit the specific type of the elastic member 25.

[0064] In addition, the shape of the resisting portion 412 of the present application can be in various styles. For example, the resisting portion 412 can be annular. In this case, the resisting portion 412 is an integral annular structure, and the cross-section of the through hole 411 is a circular structure. The resisting portion 412 is set to be annular to reduce the difficulty of processing. For another example, the resisting portion 412 can also be a block structure, and the number of the resisting portions 412 is multiple, and the multiple resisting portions 412 are arranged at intervals, and the multiple resisting portions 412 surround the wall of the through hole 411, which can save materials and costs.

[0065] In some embodiments, the fixed end 41 includes a fixing portion 413 corresponding to the end surface of the connecting sleeve 22 facing away from the connecting member 21 and a supporting portion 414 connected to the fixing portion 413. The supporting portion 414 extends from the fixing portion 413 toward one end of the connecting sleeve 22 toward the direction close to the wheel axle 210. The supporting portion 414 is used to support the connecting sleeve 22, which can make the working state of the connecting sleeve 22 more stable. The supporting portion 414 can also ensure the coaxiality of the third threaded hole 2212 of the connecting sleeve 22 and the through hole 411 on the fixed end 41, which is more conducive to the locking of the locking member 23.

[0066] Optionally, the connector 21 of the present application is threadedly connected to the axle 210, and the connector 21 is sleeved on the outside of the axle 210. A threaded hole is provided at one end of the connector 21 away from the axle 210, so that it can be threadedly connected to the sleeve screw 24. Specifically, the connector 21 of the present application is a nut, and the axle 210 is provided with a threaded section, and the nut is adapted to the threaded section on the axle 210.

[0067] In the present application, the frame body 40 includes a first support frame 42 and a second support frame 43 which are spaced apart from each other, and a storage space for placing the bicycle wheel 200 is formed between the first support frame 42 and the second support frame 43. Fixed ends 41 are provided on the tops of the first support frame 42 and the second support frame 43, and the two fixed ends 41 correspond to the two ends of the wheel axle 210 respectively. It can be understood that the locking unit 20 also has two groups, and the two groups of locking units 20 respectively fix the two fixed ends 41 to the two ends of the wheel axle 210.

[0068] In addition, the training stand of the present application also includes a resistance device. Specifically, the resistance device is a motor installed on the rear wheel hub. The motor can apply a force to the rear wheel hub to apply riding resistance during riding. Compared with the resistance of training stands on the market, which is achieved by increasing tire friction, the resistance device of the present application can adjust the riding resistance, thereby flexibly adjusting the difficulty of riding training according to actual needs.

[0069] The utility model also proposes an intelligent bicycle with a training function, which includes a training bracket. The specific structure of the training bracket refers to the above embodiment.
