The invention discloses a trolley supporting frame structure and a trolley. The trolley supporting frame structure comprises a bearing plate, a frame structure, a pull rod and moving wheels. A mounting groove is formed in the bearing plate, and the frame structure is embedded in the mounting groove; the pull rod is assembled on the outer frame; and the moving wheels are assembled at the bottoms of the bearing plate and the frame structure. According to the trolley, the assembling frame structure is embedded in the bearing plate, so that the overall structural strength of the trolley is improved; the trolley pull rod is assembled on the frame structure, so that the working load of the bearing plate is reduced when the pull rod is pulled, and the stability of the pull rod and trolley assembly structure and the pull rod pulling operation is improved; the moving wheel assemblies are assembled on the frame structure and the bearing plate simultaneously, and the overall structural strength of the trolley is improved. According to the trolley, independent assembly or associated assembly of the handrail and the moving wheels can be achieved so as to meet different use requirements; the frame structure, the bearing plate, the structure, the moving wheels and the handrail share assembly holes and bolts, so that the material cost and the assembly complexity are reduced.
本发明公开了一种手推车支撑框架结构及手推车,包括承重板、框架结构、拉杆以及移动轮;承重板,其上设置安装槽,框架结构嵌设在安装槽内;拉杆,装配在外框上;移动轮,装配在承重板和框架结构底部。本发明的手推车通过在承重板内嵌设装配框架结构,提高其整体的结构强度;本手推车拉杆装配在框架结构上,由此降低拉动拉杆时承重板的工作负荷,并提高拉杆与手推车装配结构以及拉杆拉动操作的稳定性;移动轮组件同时装配在框架结构和承重板上,提高手推车整体结构强度。本手推车可实现扶手与移动轮的独立装配或关联装配,以适配不同的使用需求;框架结构与承重板、上述结构与移动轮、扶手共用装配孔和螺栓,以降低材料成本和装配复杂度。
