The invention discloses a novel universal trundle. The novel universal trundle comprises a body, the body comprises an inner deformation part and an outer fixing part surrounding the inner deformation part in the middle, an upper connecting face is arranged at the upper end of the outer fixing part, a lower mounting face is arranged at the lower end of the inner deformation part, and a plurality of spherical grooves are formed in the inner deformation part. A plurality of small round openings communicated with the spherical groove are formed in the middle of the lower installation face, balls are installed in the spherical groove in a rolling mode, the diameter of the balls is larger than that of the small round openings, and the balls are partially exposed out of the spherical groove from the small round openings. According to the universal trundle, the bearing range of a chair or a stool is limited through elastic deformation of the inner deformation part, when the bearing range is exceeded, the universal trundle plays a stable supporting role, and when the bearing range is not exceeded, balls of the universal trundle make contact with the ground, and the effect of facilitating movement of the chair or the stool is achieved. The universal trundle has the advantages of being simple in structure, convenient to machine, low in cost and convenient to use.

    本发明公开了一种新型万向脚轮,包括有本体,本体包括有内形变部和将内形变部包围在中间的外固定部,外固定部的上端设有上连接面,内形变部的下端设有下安装面,所述内形变部内设有若干球形槽,下安装面的中部设有若干分别连通球形槽的小圆口,球形槽内可滚动的安装有滚珠,滚珠的直径大于小圆口的直径,滚珠部分从小圆口处露出球形槽。本发明的万向脚轮,依靠内形变部的弹性形变限定椅子或凳子的承重范围,超过该承重范围时,万向脚轮起到稳定支撑作用,不超过该承重范围时,万向脚轮的滚珠接触地面,起到方便椅子或凳子移动的作用。本发明的万向脚轮具有结构简单,加工方便、成本低,使用方便的优点。
