The nvention discloses a wheel deviation prevention structure for a baby carriage. The wheel deviation prevention structure comprises a wheel axle and a wheel frame, the wheel axle is inserted into the wheel frame, a front axle wheel and the wheel frame are rotationally connected and are kept in a non-separation state, deviation prevention pieces are arranged between the wheel frame and the wheel axle, the deviation preventing pieces are symmetrically arranged along the axis of the wheel axle and are extruded between the wheel frame and the wheel axle in the radial direction of the wheel axle. Due to the fact that the deviation preventing pieces are extruded between the wheel axle and the wheel frame, the deviation preventing pieces make contact with the wheel axle, rotation between the wheel axle and the wheel frame is limited, the phenomenon that the wheels suddenly steer is reduced, and the safety performance and the structural stability of the baby carriage are improved; and when steering is needed, steering can be achieved only by manually increasing the steering force on the cart handle, unlocking operation does not need to be carried out on the wheels independently, and operation is more convenient and efficient.

    本发明公开了一种用于儿童手推车的车轮防偏结构,包括车轮轴和车轮架,所述车轮轴插入所述车轮架中,所述前轴轮与所述车轮架转动连接且二者存在保持不脱离状态,所述车轮架与所述车轮轴之间设置有防偏件,所述防偏件沿所述车轮轴的轴线对称设置,且沿着所述车轮轴的径向挤压在所述车轮架与所述车轮轴之间。本发明中由于防偏件挤压在车轮轴与车轮架之间,使得防偏件与车轮轴接触,限制了车轮轴与车轮架之间的旋转,从而起到降低车轮突然发生转向的现象发生,增加了儿童手推车的安全性能和结构稳定性;并且当需要转向时,只需手动增大对推车把手的转向力就可以实现转向,无需单独对车轮实施解锁操作,使得操作更加的方便高效。
