A disclosed trundle comprises a fixing plate used for being installed on furniture and an inserting rod used for being installed on a rotating shaft of a rolling wheel, the fixing plate is provided with a round pipe used for inserting the inserting rod, the fixing plate is fixedly connected with the round pipe, the plane of the fixing plate is perpendicular to the central axis of the round pipe, the inserting rod is fixedly connected with the rotating shaft of the rolling wheel, and the upper end of the inserting rod is inserted into the circular pipe through the lower end of the circular pipe and is a conical rotating body. By adopting the technical scheme, the trundle has the beneficial effects that the conical rotating body is arranged at the upper end of the inserting rod, so that the rotating torque between the inserting rod and the circular tube is greatly reduced, the probability of jamming between the inserting rod and the circular tube is reduced, and the product quality of the trundle is improved.

    本发明公开了一种脚轮,包括用于安装在家具上的固定板、用于安装滚轮转轴上的插杆,固定板设置有用于插插杆的圆管,固定板与圆管固定连接且固定板的平面与圆管的中心轴线垂直,插杆与滚轮的转轴固定连接,插杆的上端从圆管的下端插入圆管内,插杆的上端呈圆锥形旋转体。采用本技术方案的有益效果:通过插杆的上端设置成圆锥形旋转体,使插杆与圆管之间转动扭矩大大变小,减小插杆与圆管之间卡死的几率,提高了脚轮的产品品质。
