When the foldable shopping cart needs to be used, the base component 3 is rotated towards one side of the pull rod component 1 close to the shopping cart bag 2, so that the base component 3 and the pull rod component 1 are unfolded, and simultaneously, the shopping cart bag 2 is released along with the rotation of the base component 3, so that the shopping cart belt 2 is unfolded three-dimensionally to have the function of containing articles.
When not splendid attire article, base subassembly 3 is kept away from shopping cart bag 2 direction to pull rod assembly and is rotated, when base subassembly 3 rotated to be parallel with pull rod assembly 1, and shopping cart bag 2 is pulled to the flat extreme position of exhibition by base subassembly 3, and the shopping cart area of automatic arrangement avoids the manual process of arranging folding shopping cart area 2 of user, simplifies folding process, improves user and accomodates efficiency and user experience. As the base assembly 3 continues to rotate, the middle of the cart bag 2 is blocked by the bottom of the base assembly 3, and the flattened cart bag 2 bends around wrapping around the base assembly 3 and begins to fold.
Preferably, connecting pieces 19 are respectively arranged at the upper end and the lower end of the shopping cart bag 2, a connecting structure is arranged on each connecting piece 19, the connecting pieces 19 can be detachably connected with the pull rod connecting parts 12 and the base connecting parts 10 through the connecting structures after bypassing the pull rod connecting parts 12 and the base connecting parts 10, and folding connecting pieces are further arranged on the connecting pieces 19. The shopping cart bag 3 after folding is connected through the folding connecting piece that sets up on two connection pieces 19, and the folding state of unable adjustment base subassembly 3 and pull rod assembly 1 is conveniently accomodate. As shown in the figure, a user can lift the folding shopping cart through the pull rod assembly 1, and the folding shopping cart is convenient to carry. In the present embodiment, the connection structure and the folding connection structure are implemented by hook and loop fasteners, and those skilled in the art should be able to derive the technical teaching that the connection structure and the folding connection structure can also be connection structures such as button assembly, zipper assembly, etc.
When the shopping cart bag needs to be replaced and washed, a user can detach the shopping cart bag 2 in a mode that the connecting sheet 19 is separated from the pull rod connecting part 12 and the base connecting part 10 through the separation connecting structure, so that the shopping cart bag 2 is convenient to disassemble and assemble.
Furthermore, the pull rod assembly 1 is rotatably connected with a support frame assembly 4, the support frame assembly 4 is tilted upwards or downwards and the pull rod assembly 1 is obliquely arranged to support the base assembly 3 and the pull rod assembly 1 to be unfolded, or the support frame assembly 4 is tilted upwards and can be folded with the pull rod assembly 1. When the pull rod assembly 1 and the base assembly 3 are unfolded, the support frame assembly 4 rotates to enable the base assembly 3 to lean against the support frame assembly 4, the base assembly 3 and the pull rod assembly 1 form a stable triangle, and the support base assembly 3 and the pull rod assembly 1 are kept in a stable structure when being unfolded.
Preferably, the supporting frame assembly 4 comprises a U-shaped supporting body 5, the supporting body 5 is provided with a base through groove 6 which passes through along with the rotation of the base assembly 3, a supporting rod 7 is arranged in the base through groove 6, and the base assembly 3 and the pull rod assembly 1 are arranged to lean against the supporting rod 7 to be unfolded when being unfolded. The supporting rod 7 heightens the base assembly 3 to prevent a user from excessively bending, and to improve the removal degree of articles in the shopping cart.
Further, a connecting clamping groove 8 corresponding to the supporting rod 7 is formed in the base assembly 3, and when the base assembly 3 and the pull rod assembly 1 are unfolded, the supporting rod 7 and the connecting clamping groove 8 are connected in a clamped mode to enable the pull rod assembly 1, the base assembly 3 and the support frame assembly 4 to be fixedly connected. The base assembly 3 and the support frame assembly 4 are lowered away from the support rods 7 under the weight of the items in the shopping cart bag 2 and other external forces.
