The invention discloses a movable trundle structure which comprises a supporting plate, a flat plate, a support, steel balls and wheels; the flat plate is fixedly arranged at the bottom of the supporting plate, the support is fixedly arranged in the middle of the lower surface of the flat plate through a three-level center nail, steel balls are arranged on the two sides of the three-level center nail, a reinforcing plate is arranged at the bottoms of the steel balls, the steel balls are located between the flat plate and the reinforcing plate, and the wheels are arranged on one side of the support. A traditional trundle is connected simply through a center nail, so that the trundle is rigidly impacted in the use process, and is easily damaged; according to the movable trundle structure disclosed in the invention, the steel balls are arranged between the flat plate and the support, the steel balls can achieve a good buffering effect when encountering rigid impact in the using process ofthe trundle, the whole movable trundle structure can be protected, steering walking does not deviate, and the movable trundle structure is simple in structure and good in practicability.

    本发明公开了一种活动脚轮结构,包括支撑板、平板、支架、钢珠以及轮仔,所述支撑板的底部固定设置有平板,所述平板下表面的中部通过三级中心钉固定设置有支架,所述三级中心钉的两侧均设置有钢珠,所述钢珠的底部设置有加固板,所述钢珠位于平板与加固板之间,所述支架的一侧设置有轮仔。该活动脚轮结构,针对传统脚轮都是单纯的利用中心钉进行连接,使得脚轮在使用过程中受到刚性冲击,容易出现损坏,通过设置钢球,在平板与支架之间设置钢球,使得脚轮使用过程中,遇到刚性冲击,钢球能够起到较好的缓冲效果,利于对整个活动脚轮结构进行保护,而且转向行走不偏移,结构简单,实用性较好。
