The invention provides a trolley bottom supporting frame and a trolley. The trolley bottom supporting frame aims at solving the problem that in the prior art, a bottom supporting frame of a trolley is poor in bearing capacity. A trolley bottom supporting frame comprises a handle seat, a plurality of supporting assemblies are arranged around the handle seat, each supporting assembly comprises a first support and a second support, and the first supports are located on the upper sides of the second supports. The ends, close to the handle base, of the first support and the second support are hinged to the handle base. When the bottom supporting frame is in a folded state, all the first supports and the second supports rotate in the direction of being close to each other and are close to each other. When the bottom supporting frame is in the unfolded state, all the first supports and the second supports rotate in the direction away from each other and are unfolded. According to the bottom supporting frame, double-layer supporting enables the bottom supporting frame to be higher in bearing capacity and better in stability.

    本发明提供了一种手推车底部支撑架及手推车,旨在解决现有技术中的手推车的底部支撑架承重能力差的问题。一种手推车底部支撑架,包括提手座,环绕所述提手座上设有若干组支撑组件,每组所述支撑组件均包括第一支架和第二支架,并且所述第一支架位于所述第二支架的上侧,所述第一支架和第二支架靠近所述提手座的一端均铰接在所述提手座上;当所述底部支撑架处于折叠状态时,所有所述第一支架和第二支架均向相互靠拢的方向转动且靠拢;当所述底部支撑架处于展开状态时,所有所述第一支架和第二支架均向相互远离的方向转动且展开。本发明中,双层支撑使得底部支撑架承重能力更强,稳定性更好。
