Dual-purpose foldable carrying cart

Abstract

The invention discloses a dal-purpose foldable carrying cart, which can be switched from a two-wheel pushing cart and a four-wheel pulling cart, and can be folded into a flat-type carrying cart. By adopting a foldable structure, carrying and use of a delivery man can be facilitated, and occupied space of a compartment of a delivery cart can be reduced, and the foldable-type integrated structure isflat, and therefore inserting-type arrangement can be conveniently carried out. The dual-purpose foldable carrying cart is characterized in that bottom sides of two sides of a movable pushing rack are respectively connected with a supporting base, and a supporting rod is disposed between the supporting bases. The two ends of the supporting rod are respectively connected with the supporting bases.The supporting rod is provided with two universal wheels, which are respectively close to the two ends of the supporting rod. One end of each of the two sliding rods is respectively disposed on the bottom sides of the two sides of the movable pushing rack in a hinged manner. The other ends of the sliding rods are bent outwards to be extended for a distance, and then bent in a horizontal directionto be extended. The two bottom wheel bases are respectively rotatably disposed on the two sliding rods in a sleeved manner, and the bottom wheel bases are close to the other ends of the sliding rods,and the bottom wheel bases are provided with bottom large wheels.

Description
