The invention relates to the technical field of trundles, and particularly discloses a high-load universal wheel which comprises a top plate, a rotating mechanism, a supporting frame, a wheel and a first rotating shaft, the bottom of the top plate is fixedly connected with the top end of the rotating mechanism, the bottom end of the rotating mechanism is fixedly connected with the top end of the supporting frame, and the wheel is arranged in the supporting frame; when a user pushes the trolley containing goods to pass through the deceleration strip, wheels make contact with protrusions of the deceleration strip and are extruded by the deceleration strip, pressure is transmitted to the rotating mechanism through the wheels, the first rotating shaft and the supporting frame in sequence, the first spring between the supporting cylinder and the rotating rod contracts, and the supporting cylinder moves upwards relative to the sleeve; the first clamping block is clamped into the first clamping groove, so that the supporting cylinder and the rotating rod are relatively clamped and cannot rotate relatively, the wheels cannot deflect due to the too large attack angle, the advancing direction of the trolley cannot be changed, the trolley can stably pass through the speed bump, and the probability of accidents is reduced.
本发明涉及脚轮技术领域,具体公开了一种高载重万向轮,包括顶板、转动机构、支撑架、轮子和第一转轴,所述顶板的底部与转动机构的顶端固定连接,所述转动机构的底端与支撑架的顶端固定连接,所述支撑架内设有轮子,当使用者推动装有货物的手推车经过减速带时,轮子接触减速带凸起,轮子受到减速带的挤压,压力依次通过轮子、第一转轴、支撑架传递到转动机构,支撑筒和转杆之间的第一弹簧收缩,支撑筒相对套筒向上移动,使得第一卡块卡入第一卡槽内,进而使得支撑筒和转杆相对卡紧,使其不能发生相对转动,使得轮子不会因为攻角过大发生偏转,手推车的行进方向不会发生变化,可以稳定的通过减速带,减少了意外事故发生的概率。
