The invention relates to the technical field of medical transportation equipment and especially relates to a universal wheel with a shock-proof mechanism. The universal wheel comprises a universal wheel body, a roller bearing is arranged in the middle of the universal wheel body, a plurality of fan-shaped rubber blocks are arranged on the outer side of the universal wheel body, the universal wheelbody is connected with the fan-shaped rubber blocks through buffer pieces, the universal wheel body is connected with the fan-shaped rubber blocks through limiting connecting mechanisms, and buffer springs are connected between the universal wheel body and the fan-shaped rubber blocks. The invention discloses a universal wheel with a shock absorption mechanism. Buffering pieces are arranged on the universal wheel body and the fan-shaped rubber blocks. The universal wheel body is connected with the fan-shaped rubber block through a limiting connecting mechanism and a buffer spring. In the invention, the connecting stability of the universal wheel is guaranteed, meanwhile, the damping performance of the universal wheel is improved, so that when the universal wheel passes through the unevenground, vibration can be reduced or eliminated, the stability of equipment such as a medical cart, a manipulator and a wheelchair is improved, the comfort degree of a patient is improved, and articleson the cart are prevented from toppling over.

    本发明涉及医用运输设备技术领域,尤其是一种具有避震机构的万向轮,包括万向轮轮体,万向轮轮体中部设有滚柱轴承,万向轮轮体外侧设有若干个扇形橡胶块,万向轮轮体与扇形橡胶块通过缓冲片连接,万向轮轮体和扇形橡胶块之间通过限位连接机构连接,且万向轮轮体与扇形橡胶块之间连接有缓冲弹簧。本发明的一种具有避震机构的万向轮,在万向轮轮体与扇形橡胶块设置缓冲片,且将万向轮轮体与扇形橡胶块通过限位连接机构和缓冲弹簧连接,保证了万向轮连接的稳定性的同时,提高了万向轮的减震性能,在经过高低不平的地面时,能够减少或者消除震荡,增加医用推车、推床,轮椅等设备的平稳性,提高患者的舒适度,避免推车上的物品的倾倒。
