Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, the utility model provides a technical solution: a brake wheel that is easy to disassemble and replace, including a rim 1, a through hole 2 is opened at the center of the rim 1, and the rim 1 passes through the through hole 2 Slidingly arranged on the rotating shaft 3, the limiting block 4 is fixedly arranged on the rotating shaft 3, and there are multiple limiting blocks 4, and the limiting blocks 4 are arranged symmetrically with respect to the center line of the rotating shaft 3, so that the rim 1 can be rotated And it is more stable when braking. The inner wall of the through hole 2 is provided with a limit groove 11 that matches the limit block 4.
