Description

Technical Field

[0001] This utility model relates to the field of folding trolley technology, and specifically to a folding shopping cart. Background Technology

[0002] Traditional shopping carts typically feature a rigid frame and wheels, resulting in a fixed size that prevents them from folding. When not in use, consumers often need to find a fixed storage space for their carts, creating additional inconvenience. This is especially problematic in space-constrained environments like homes or offices. Furthermore, the fixed size of traditional shopping carts makes them difficult and impractical to carry. Therefore, the non-foldable nature of traditional shopping carts limits their convenience and flexibility.

[0003] To address this issue, some shopping cart designs incorporate foldable designs. For example, Chinese utility model patent CN202323578653.1 discloses a foldable shopping cart with detachable handles. The left and right panels of the cart each have a first fold line and a second fold line. The left panel is folded along the first fold line, and the right panel is folded along the second fold line. When folding, first rotate the movable end of the bottom panel until it is parallel to the rear panel. Then, push the front and rear panels together, causing the left panel to fold along the first fold line and the right panel along the second fold line, bringing the front and rear panels closer together. When the cart needs to be stored, rotate the bottom panel upwards to fold it parallel to the rear panel. When goods need to be transported, lower the bottom panel, which acts as a support for the cart body.

[0004] When the shopping cart needs to be stored, the bottom panel must first be rotated upwards to be parallel to the back panel before the cart can be folded. This process is cumbersome, and the creases on the side panels are formed by the cooperation between the rotating shaft and the mounting buckle. This structure is relatively complex and has high production costs. Utility Model Content
