The invention relates to the field of trundles, in particular to an improved trundle assembly which comprises a trundle and a support, the trundle is rotationally installed on the support in the horizontal direction, the improved trundle assembly further comprises a connecting plate, a first connecting body and a second connecting body, the support is rotationally installed on the connecting plate in the vertical direction, and the first connecting body is connected with the second connecting body. The first connecting body is fixed to the connecting plate, the second connecting body is fixed to the lower portion of an object to be moved and connected with the first connecting body through a hook-and-loop fastener in a pasted mode, the connecting plate is a circular plate with the outer diameter of D1, the diameter of the trundles is D2, and D1: D2 is larger than or equal to 5: 4. The proportional relation range of the outer diameter D1 of the connecting plate and the diameter D2 of the trundle is limited, buffering between the connecting plate and the to-be-moved object is guaranteed, and meanwhile the problem that the connecting plate and the to-be-moved object are prone to being directly torn off due to the fact that the field angle formed by impact is too large can be solved.
本发明涉及脚轮领域,具体涉及一种改造脚轮组件,包括脚轮和支架,所述脚轮沿水平方向转动安装于所述支架,所述改造脚轮组件还包括连接板、第一连接体和第二连接体,所述支架沿竖直方向转动安装于所述连接板,所述第一连接体固定于所述连接板,所述第二连接体固定于待移动物品下方,并与所述第一连接体通过魔术贴粘贴连接,所述连接板为外径D1的圆板,所述脚轮的直径为D2,D1:D2≥5:4。本申请中限定了连接板的外径D1与脚轮的直径D2的比例关系范围,在保证连接板与待移动物品之间的缓冲的同时,还能降低连接板与待移动物品因冲击形成的张角过大而易直接撕脱的问题。
