The invention discloses a universal trundle structure with an autonomous braking function, and aims to provide the universal trundle structure with the autonomous braking function. The device comprises a rotating column, a connecting block and a roller, a placement groove is formed in the bottom of the connecting block, the roller is arranged in the placement groove, the two ends of the roller are rotationally connected with the two sides of the placement groove, a fixing mechanism is arranged on the roller and connected with the roller, and one end of the roller penetrates through the connecting block and then is arranged on the outer side of the connecting block. An overspeed fixing assembly is arranged at the end, arranged on the outer side of the connecting block, of the roller and connected with the roller, and the upper end of the connecting block is connected with the rotating column. The universal caster has the beneficial effects that when the speed of the universal caster is too high, automatic braking can be achieved, better braking is achieved, the fixing block is prevented from rebounding, fixing is automatically relieved, the speed of the universal caster during downhill is reduced, fixing when the rolling wheel is static is achieved, fixing reliability is guaranteed, steering is convenient, overall fixing is achieved, and the caster can be protected.

    本发明公开了一种自主式制动的万向脚轮结构,旨在提供一种自主式制动的万向脚轮结构。它包括旋转柱、连接块和滚轮,连接块的底部设有放置槽,滚轮置于放置槽内,滚轮的两端均与放置槽的两侧转动连接,滚轮上设有固定机构,固定机构与滚轮连接,滚轮的一端贯穿连接块后置于连接块外侧,滚轮置于连接块外侧的一端设有过速固定组件,过速固定组件与滚轮连接,连接块的上端与旋转柱连接。本发明的有益效果是:当万向脚轮速度过快时可以自动制动,更好的制动,防止固定块弹回,自动解除固定,减小万向轮下坡时的速度,实现滚轮静止时的固定,保证固定的可靠性,转向较为方便,实现整体的固定,可以对脚轮进行保护。
