The invention provides a universal trundle which comprises a trundle body and a plurality of supporting rods, the trundle body comprises a circular cavity and an outlet, the outlet is located in the bottom of the circular cavity, and a plurality of balls are arranged in the circular cavity; and the trundle ball is matched with the circular cavity, part of the trundle ball is located in the circular cavity and abuts against the ball, and the other part of the trundle ball is arranged in a protruding mode relative to the outlet. The friction force between the trundle ball and the inner wall of the circular cavity is reduced through the arrangement of the balls, smooth rolling of the trundle ball is improved, then smooth movement of the trundle body is achieved, the trundle ball can rotate by 360 degrees through the arrangement of the trundle ball in the circular cavity, and then universal movement of the trundle body and the universal trundle is achieved. The universal moving device is simple in structure, universal moving can be achieved, smooth steering can also be achieved, and application and popularization are facilitated.
本申请提供一种万向脚轮,包括:脚轮本体,包括圆形空腔和出口,所述出口位于所述圆形空腔的底部,所述圆形空腔内设有多个滚珠;脚轮球,与所述圆形空腔适配,部分位于所述圆形空腔内,与所述滚珠抵接,另一部分相对于所述出口凸出设置。所述滚珠的设置有利于降低脚轮球与圆形空腔内壁的摩擦力,提升脚轮球的顺滑滚动,进而实现脚轮本体的顺滑移动,脚轮球在圆形空腔内的设置使得脚轮球能够朝向360°的方向转动,进而实现脚轮本体和万向脚轮的万向移动。本申请结构简单,既能够实现万向移动,还能够实现丝滑转向,有利于推广应用。
