Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

According to the drawings of fig. 1, fig. 2 and fig. 3, the foldable logistics trolley comprises a first side plate 1, a second side plate 2, a pulley bracket 3, a pulley 4, a first bottom plate 5, a second bottom plate 6, a supporting block 7 and a connecting rod 8, wherein the first side plate 1 and the second side plate 2 are rectangular frames, and the bottom end side of each vertical side is provided with a convex block 15. 5 one ends of first bottom plate cup joint on connecting rod 8, and connecting rod 8 is established on
