Problems solved by technology
Since only one end of the screw is fixed to the L-shaped support frame, the screw is easy to loosen and fall off from the L-shaped support frame; it will also cause the training wheel to be stressed unevenly on the screw, and long-term use will cause uneven wear between the training wheel and the screw. 1. The part of the inner hole of the auxiliary wheel that wears a lot is easy to be squeezed and cracked, thereby shortening the service life of the auxiliary wheel; in addition, the L-shaped support frame is easily deformed by external force

The invention discloses an auxiliary wheel supporting device of a child bicycle. The auxiliary wheel supporting device comprises a supporting frame, an auxiliary wheel, a screw shaft, a fixing nut and an anti-disengagement clamping gasket. One end of the supporting frame is made into an L shape, wherein the straight side is provided with a fixing hole; the other end of the supporting frame is made in a U shape, wherein the screw shaft is arranged on the two straight sides of the U shape. The auxiliary wheel is arranged in the middle of the screw shaft. One end of the screw shaft is provided with a threaded head connected with the fixing nut. An anti-disengagement clamping groove is formed in the surface of the threaded head on the outer side of the fixing nut. The anti-disengagement clamping gasket is arranged in the anti-disengagement clamping groove. The two sides of the auxiliary wheel are provided with a left spacer sleeve and a right spacer sleeve respectively. The auxiliary wheel supporting device is simple in structure, convenient to install, remarkable in effect and capable of effectively solving the technical problems that an existing child bicycle rear auxiliary wheel supporting frame and auxiliary wheel screws get loose and an auxiliary wheel is abraded unevenly.
Description
technical field [0001] The invention belongs to the technical field of children's bicycle manufacturing, and in particular relates to a supporting device for auxiliary wheels of children's bicycles. Background technique [0002] Children's bicycle is one of the favorite gifts for children aged 4-6, and it is also the best tool for children to learn to ride a two-wheeled bicycle. Most children's bicycles are equipped with auxiliary wheels on both sides of the rear wheel to keep the body stable. Auxiliary wheel is fixed on the rear wheel mounting frame by bracing frame, and existing auxiliary wheel supporting device adopts round pipe or flat steel to bend into L-shaped more, and auxiliary wheel is fixed on the lower end of L-shaped by screw. Since only one end of the screw is fixed to the L-shaped support frame, the screw is easy to loosen and fall off from the L-shaped support frame; it will also cause the training wheel to be stressed unevenly on the screw, and long-term us...
