The invention relates to the technical field of trundles, and discloses a free steering trundle mechanism capable of fixedly bearing heavy load. The mechanism comprises a common support frame, the topof the common support frame is fixedly connected with a fixed connecting plate, and the bottom of the fixed connecting plate is movably connected with a fixed bolt. According to the free steering trundle mechanism capable of fixedly bearing heavy load, a universal roller connecting frame is driven to rotate through universal rollers; the universal roller connecting frame drives a rotary rolling bearing to rotate; because the common support frame is matched for use, the effect of free steering of the universal rollers is achieved; a rotary pedal moves to drive a universal wheel friction fixingplate to make contact with the universal roller to fix the roller, a lifting stop nut is rotated, the lifting stop nut drives a lifting screw to move, the lifting screw drives a supporting trapezoidal base to move downwards, then the lifting supporting nut and other mechanisms are used in cooperation, so that the effect of large fixing and bearing capacity is achieved.

    本发明涉及脚轮技术领域,且公开了一种可固定承受重载的自由转向脚轮机构,包括共用支撑架,所述共用支撑架的顶部固定连接有固定连接板,所述固定连接板底部活动连接有固定螺栓。该可固定承受重载的自由转向脚轮机构,通过万向滚轮带动万向滚轮连接架旋转,万向滚轮连接架带动旋转滚动轴承旋转,再通过共用支撑架的配合使用,从而达到万向滚轮自由转向的效果,通过移动旋转脚踏板,旋转脚踏板带动万向轮摩擦固定板与万向滚轮接触,对滚轮进行固定,旋转升降止挡螺母,升降止挡螺母带动升降螺杆位移,升降螺杆带动支撑梯形座下移,再通过升降支撑螺母等机构的配合使用,从而达到固定承载能力大的效果。
