[0001] The utility model relates to the technical field of auxiliary wheel mechanisms, and particularly relates to a bicycle auxiliary wheel mechanism. Background Art

[0002] During the process of learning to ride a bicycle, in order to assist beginners in practicing, auxiliary wheels are usually installed on the frame of the bicycle, and the auxiliary wheels are located on both sides of the rear wheel.

[0003] Existing auxiliary wheels usually have a fixed height. When people purchase them, due to the different sizes of bicycle wheels, it is impossible to install the auxiliary wheels on bicycle wheels of different sizes during the installation of the auxiliary wheels. Therefore, we propose a bicycle auxiliary wheel mechanism to facilitate the installation of auxiliary wheels on bicycle wheels of different sizes. Content of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a bicycle auxiliary wheel mechanism.

An adjusting mechanism is installed on the plate wall of the cross plate. The adjusting mechanism is composed of a sleeve, a locking bolt, a support plate, a vertical plate, a through hole, a threaded hole, a reinforcing plate and a connecting plate. The connecting plate is installed on the plate top of the cross plate through bolts. The sleeve is welded on the plate top of the connecting plate. The support plate is inserted and connected to the inner wall of the sleeve. A number of threaded holes for connecting the locking bolts are opened on the plate wall of the support plate. The locking bolt is threadedly connected to the wall of the sleeve. The vertical plate is welded on the plate top of the support plate. The through hole is opened on the plate wall of the vertical plate. The reinforcing plate is welded on the wall of the sleeve.

[0006] By adopting the above technical solution, when installing an auxiliary wheel on bicycle wheels of different sizes, since an adjusting mechanism is installed on the plate wall of the cross plate, the adjusting mechanism is composed of a sleeve, a locking bolt, a support plate, a vertical plate, a through hole, a threaded hole, a reinforcing plate and a connecting plate. According to the size of the bicycle wheel, the personnel loosen the locking bolt. After the locking bolt is separated from the threaded hole at the support plate, the personnel pull the support plate so that the support plate moves within the sleeve. After the position of the support plate within the sleeve is adjusted, the personnel turn the locking bolt so that the locking bolt is threadedly connected to the corresponding threaded hole, realizing the fixation of the support plate within the sleeve. Since a vertical plate is welded to the top of the support rod, and a through hole is provided in the plate wall of the vertical plate, the rotating shaft at the bicycle hub is inserted into the through hole, and then an external nut is threadedly connected to the rotating shaft at the bicycle hub, and the nut presses against the vertical plate, realizing the fixation of the vertical plate. Since a reinforcing plate is welded to the wall of the sleeve, and the wall of the reinforcing plate is bolted to the wall of the pedal, the support and fixation of the sleeve are realized, and the connection between the auxiliary wheel and the hubs of bicycles of different sizes is realized.

[0007] Specifically, it further includes an auxiliary mechanism, and the auxiliary mechanism is installed on the plate wall of the cross plate.

[0008] By adopting the above technical solution, the bicycle can be assisted in riding through the auxiliary mechanism.

[0009] Specifically, the auxiliary mechanism is composed of a wheel plate A, a wheel plate B, an inclined plate and an auxiliary wheel. One end of the cross plate is bolted with the wheel plate A, the bottom of the cross plate is welded with the wheel plate B, an auxiliary wheel is rotatably installed between the wheel plate A and the wheel plate B, one end of the bottom of the cross plate is bolted to one end of the inclined plate, and the other end of the inclined plate is bolted to the wall of the wheel plate B.

[0010] By adopting the above technical solution, when installing the auxiliary wheel on the bicycle, since the auxiliary mechanism is installed on the plate wall of the cross plate, and the auxiliary mechanism is composed of a wheel plate A, a wheel plate B, an inclined plate and an auxiliary wheel. Since the wheel plate A is bolted to the plate wall of the cross plate, and the wheel plate B is welded to the bottom of the cross plate, the auxiliary wheel is rotatably installed between the wheel plate A and the wheel plate B through bearings. Since one end of the bottom of the cross plate is bolted to one end of the inclined plate, the fixation of the inclined plate is realized, and the other end of the inclined plate is bolted to the wheel plate B, thus realizing the reinforcement of the wheel plate B. The bicycle can be assisted in riding through the auxiliary wheel.

[0011] Specifically, a pedal is bolted to the plate wall of the cross plate.

[0012] By adopting the above technical solution, it is convenient for the carrying personnel to place their feet on the pedal.
