Abstract:
A bundle-type folding wagon, comprising a plurality of vertical base frames, a plurality of side folding frames, and a bottom folding frame connected between all the vertical base frames. The bottom folding frame comprises a central seat located at the center and consisting of an upper plate and a lower plate which can get close to or far away from each other in the vertical direction, and a plurality of bottom linking rod groups consisting of a plurality of bottom rods; each bottom linking rod group is separately connected between the central seat and the corresponding vertical base frame; a lifting/lowering frame is arranged on each vertical base frame in a mode of sliding for lifting or lowering in the vertical direction; each side folding frame is arranged between two adjacent vertical base frames and two adjacent lifting/lowering frames; when the bundle-type folding wagon is at an unfolded position, the lifting/lowering frames are lifted upwards relative to the vertical base frames, the whole wagon is unfolded, and after unfolding, the spatial volume is large, the strength is high, and the storage capacity is high. When the bundle-type folding wagon is at a folded position, the lifting/lowering frames are lowered downwards relative to the vertical base frames, the whole wagon is folded to a bundle shape, and after folding, the volume is small.
