The pull rod lifting and collecting structure comprises a conveying plate, a connecting rod fixed to a pressing plate, a trundle rotationally installed on the connecting rod through a wheel frame, an overturning limiting piece installed on the connecting rod in a sliding mode and a first spring elastically acting on the overturning limiting piece, and the trundle comprises a torsional spring capable of acting on the trundle to rotate and collect. The first spring elastically acts on the overturning limiting piece to be attached to the wheel frame, the overturning limiting piece and the wheel frame are matched and limited through a concave-convex structure, the overturning limiting piece can limit the wheel frame to be used perpendicular to the conveying plate or to be attached to the conveying plate to be stored, a lifting part is arranged on the conveying plate, a grip is installed on the lifting part or the conveying plate in a sliding mode, and a pull rod is rotationally connected between the grip and the overturning limiting piece. Compared with the prior art, the caster has the advantages that the lifting part and the grip are kneaded, so that the caster can rotate to be attached to the conveying plate for storage, and the storage operation of the caster is simple and convenient.

    本发明公开了一种手推车车轮的拉杆拎收结构,包括运板、固定在压板上的连接杆、通过轮架转动安装在连接杆上的脚轮、滑动安装在连接杆上的翻转限位件,以及弹性作用翻转限位件的弹簧一,脚轮包括能作用脚轮转动收纳的扭簧,弹簧一弹性作用翻转限位件贴合轮架,翻转限位件与轮架间通过凹凸结构配合限位,翻转限位件能限制轮架垂直运板使用或贴合运板收纳,运板上设有拎提部,拎提部处或运板上滑动安装有握把,握把与翻转限位件间转动连接有拉杆。与现有技术相比,本发明的优点在于,通过捏合作用拎提部和握把,即能实现脚轮转动贴合运板进行收纳,脚轮的收纳操作简单便捷。
