Description

Technical Field

[0001] The utility model relates to the technical field of shopping carts, in particular to a lightweight steel folding shopping cart. Background Art

[0002] Currently, most people who do grocery shopping are women or the elderly. When the items they buy are slightly heavy, they will inevitably feel physically exhausted. For this reason, shopping carts for home use have come into being, which make it convenient for shoppers to bring large or slightly heavy items home. Since the storage baskets of existing shopping carts are mostly made of iron materials, the weight of the entire shopping cart is heavy. Therefore, the patent "CN213831784U3" proposes "a lightweight folding shopping cart" that replaces the storage basket surrounded by iron materials with a soft bag, which greatly reduces the overall weight.

[0003] However, the X-shaped bracket in this solution does not have a positioning structure, and the X-shaped bracket is prone to folding and closing during use, which will cause the frame on the top of the receiving basket to deform. For this reason, a lightweight steel folding shopping cart is proposed. Utility Model Content
