Description

Technical Field

[0001] The utility model relates to the technical field of children's bicycles, in particular to a fixing bracket for riding a children's bicycle. Background Art

[0002] Cycling is a fitness exercise that is beneficial to children's growth. Riding a bicycle can improve cardiopulmonary function, exercise lower limb muscle strength and enhance whole-body endurance. In addition, it can also exercise children's balance ability. Exercise is a child's nature, and riding a bicycle can promote the full development of children's movement and balance ability. The earlier a child rides a bicycle, the more beneficial it is for the development of his or her athletic talent.

[0003] The existing Chinese utility model patent with reference announcement number CN212890686U discloses a children's bicycle, which belongs to the field of bicycle technology. In the technical scheme, it includes a bicycle body, a connecting rod is welded at the front end of the bicycle body, and a bracket is arranged at the front end of the connecting rod, the bracket and the connecting rod are fixed by nuts, and the outer surface of the bottom end of the bracket is connected with an auxiliary wheel through a bearing, and a support rod is fixed at the top of the bicycle body, and a seat is fixed at the top of the support rod. The utility model is provided with a lifting structure composed of nuts, grooves and blocks, through which the auxiliary wheels can be completely touched when children are just learning to ride, ensuring the balance of children and preventing them from falling. After the children are proficient in riding, the height of the auxiliary wheels can be adjusted through the structure, so that the auxiliary wheels do not contact the ground, allowing children to master balance independently, speeding up the progress of learning, and the auxiliary wheels can still play a supporting role when the body of the bicycle is tilted during riding after being suspended in the air, preventing children from falling, and enhancing the practicality of the device.
