The invention relates to the technical field of universal wheels, in particular to a universal wheel for preventing sundries on a rotating shaft from being wound. A rolling wheel is rotatably connected to the middle of the inner surface of a shell, a transmission block is rotatably connected to the upper portion of the rolling wheel, transmission shafts are fixedly connected to the two sides of the transmission block, and walking wheels are rotatably connected to the bottom end of the outer surface of the rolling wheel. A rotating shaft is engaged with the lower portion of the transmission shaft, and the bottom end of the rotating shaft is fixedly connected with an adjusting block. When a blade is subjected to thrust, the spring supporting rod is stretched, and when the blade is not stressed, the blade is retracted under the action of the elastic force of the spring supporting rod, and the blade reciprocates back and forth under the mutual action of the shifting plate and the spring supporting rod to cut off a rope and other impurities to be wound, so the situations that the blade is wound on a connecting shaft of a universal wheel to cause jamming of the walking wheel, and the normal use of equipment installed on the universal wheel is affected are avoided, the winding on the universal wheel is avoided in time, and convenience of the universal wheel in use can be guaranteed.
本发明涉及万向轮技术领域,具体为一种防止转轴上杂物缠绕的万向轮,所述壳体的内表面中间位置处转动连接有滚轮,所述滚轮的上方转动连接有传动块,所述传动块的两侧固定连接有传动轴,所述滚轮的外表面底端转动连接有行走轮,所述传动轴的下方啮合有转轴,所述转轴的底端固定连接有调节块。当刀片受到推力时,弹簧撑杆拉伸,当刀片不受力时,在弹簧撑杆弹力的作用下刀片收回,在拨板和弹簧撑杆的相互共同作用下,刀片做来回往复运动,将想要缠入的绳子和一些其他杂质剪切断,避免缠绕到万向轮的连接轴上,导致行走轮卡死,影响万向轮上安装设备的正常使用,及时的避免万向轮上发生缠绕,可以保障万向轮使用时的方便性。
