Abstract
A foldable trolley comprises a supporting frame having two lateral rods with a roller disposed at each of two ends of the lateral rods, opposite inner sides of the two horizontal lateral rods being coupled interlockingly with a cross connecting rod for compressing and expanding; a supporting plate placed on the expanded supporting frame comprising a plurality of plates connected with ligaments for forming a multi-section foldable structure; and a handle set comprising two vertical supporting rods with lower ends pivotally connected to the two lateral rods of the supporting frame, and upper ends sleevely connected to a dismountable horizontal rod. Thereby, after the horizontal rod and the supporting plate of the combinational structure are dismounted, the cross connecting rod between the two lateral rods of the supporting frame can be collapsed for forming a compact structure with a decreased volume.
