DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Combined with Figures 1-6 , a bicycle auxiliary wheel connector includes a bracket 1, a mounting hole 2 and an auxiliary wheel 3. An adjusting mechanism 4 and a shock-absorbing mechanism 5 are respectively arranged on the bracket 1.

[0024] Refer to Figures 2-5 Figures 2-5 , it is further obtained that the adjusting mechanism 4 includes a telescopic bracket 409 and a telescopic groove 401 formed on the bracket 1. The telescopic bracket 409 is slidably connected to the telescopic groove 401. A clamping hole 402 is formed on the bracket 1, and a plurality of positioning holes 410 adapted to the clamping hole 402 are formed on the telescopic bracket 409. A fixed cylinder 403 is fixedly arranged on the bracket 1. A sliding block 404 is slidably connected in the fixed cylinder 403. A clamping rod 405 is fixedly arranged at one end of the sliding block 404. A pull rod 406 is fixedly arranged at the end of the sliding block 404 away from the clamping rod 405. A compression spring 407 is sleeved on the pull rod 406. The clamping rod 405 slidably penetrates through the fixed cylinder 403 and passes through the positioning hole 410 to be clamped with the clamping hole 402. The pull rod 406 slidably penetrates through the fixed cylinder 403 and is fixedly provided with a pull ring 408. One end of the compression spring 407 is fixedly connected to the sliding block 404, and the other end of the compression spring 407 is fixedly connected to the inner wall of the fixed cylinder 403.

[0025] Refer to Figure 6 Figure 6 , it is further obtained that the shock absorption mechanism 5 includes a connecting plate 502 and a mounting block 503. A sliding rod 505 is fixedly arranged on the connecting plate 502. A sliding hole 504 for slidably connecting the sliding rod 505 is formed on the mounting block 503. A shock absorption spring 506 is sleeved on the sliding rod 505. A fixed rod 501 is fixedly arranged on the connecting plate 502. The fixed rod 501 is fixedly connected to the bracket 1. The mounting block 503 is fixedly arranged on the bracket 1. One end of the shock absorption spring 506 is fixedly connected to the connecting plate 502, and the other end of the shock absorption spring 506 is fixedly connected to the mounting block 503. A limiting piece 507 is arranged at the end of the sliding rod 505 close to the mounting block 503. The limiting piece 507 is fixedly connected to the sliding rod 505.

[0026] In the actual operation process, the bicycle auxiliary wheel connector is fixedly connected to the bicycle through the mounting hole 2 on the bracket 1. The height of the auxiliary wheel is adjusted according to the height of the bicycle user. During the adjustment, the pull ring 408 is pulled to drive the pull rod 406 to drive the sliding block 404 to slide into the fixed cylinder 403. The sliding block 404 drives the clamping rod 405 to retract into the fixed cylinder 403, so that the clamping rod 405 disengages from the clamping hole 420 and the positioning hole 410 on the telescopic bracket 409, and the locking connection relationship between the bracket 1 and the telescopic bracket 409 is released. Then, the telescopic bracket 409 is slid telescopically along the telescopic groove 401 to adjust the height of the auxiliary wheel 3. When the telescopic bracket 409 is completely removed from the telescopic groove 401, the quick disassembly of the auxiliary wheel 3 can be realized, which is convenient for the maintenance and replacement of the auxiliary wheel 3. After the auxiliary wheel 3 is adjusted to the appropriate height, the pull ring 408 is released, and the sliding block 404 drives the clamping rod 405 to reset under the rebounding action of the compression spring 407. The clamping rod 405 passes through the corresponding positioning hole 410 on the telescopic bracket 409 and is re-engaged with the clamping hole 402, and the adjustment of the use height of the auxiliary wheel 3 can be completed. The operation is simple and convenient, without cumbersome operations, greatly improving the convenience of use for users;

[0027] When the auxiliary wheel 3 is in use, the mounting block 503 on the bracket 1 will vibrate with the bracket 1. The sliding rod 505 slides in the sliding hole 504 on the mounting block 503. The damping spring 506 is squeezed by the vibration of the mounting block 503. Under the elastic potential energy of the damping spring 506 itself, it can damp the vibration of the bracket 1, thereby buffering the vibration force of the auxiliary wheel 3, improving the stability of the auxiliary wheel 3 during use, and at the same time having a certain protective effect on the auxiliary wheel 3, and improving the service life of the auxiliary wheel 3.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
