[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable shopping cart, including a shopping cart basket and a seat. The top of the shopping cart basket is provided with raised guardrails on all four sides. The raised guardrails include longitudinal guardrails and transverse guardrails symmetrically arranged on both sides. Positioning components are respectively provided at the top of the two sets of longitudinal guardrails near both ends. The positioning components include slidably installed push blocks. A plug rod is fixedly installed on one side of the push block, and a positioning spring is fixedly installed on the other side of the push block. Rotating blocks are rotatably installed at the ends of the two sets of transverse guardrails near the ends of the longitudinal guardrails.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-4The present invention provides a technical solution: a foldable shopping cart, including a shopping cart basket 1 and a seat 2. The top of the shopping cart basket 1 is provided with raised guardrails 3 on all four sides. The raised guardrails 3 include longitudinal guardrails 31 and transverse guardrails 32 symmetrically arranged on both sides.

[0021] Positioning components 4 are respectively provided at the top of the two sets of longitudinal guardrails 31 near both ends. The positioning components 4 include a sliding push block 42, a plug rod 44 is fixedly installed on one side of the push block 42, and a positioning spring 43 is fixedly installed on the other side of the push block 42. Rotating blocks 5 are respectively rotatably installed at the ends of the two sets of transverse guardrails 32 near the ends of the longitudinal guardrails 31.

[0022] The shopping cart basket 1 forms a shopping cart via the seat 2, which allows customers to move the shopping cart by pushing it with the handle 21, thereby enabling them to move and carry the goods stacked inside the shopping cart basket 1 for shopping.

[0023] After the raised guardrail 3 is extended vertically from the outside through the longitudinal guardrails 31 on both sides, and then the two sets of transverse guardrails 32 are extended vertically from the inside of the shopping cart basket 1, the four sets of rotating blocks 5 are rotated to fit the adjacent ends of the longitudinal guardrails 31 and the transverse guardrails 32 together. Then, the push block 42 in the positioning component 4 can be moved so that the insertion rod 44 can squeeze the positioning spring 43, so that the insertion rod 44 can be inserted into the insertion hole at the end of the corresponding rotating block 5. In this way, the ends of the two longitudinal guardrails 31 and the transverse guardrails 32 can be stably positioned together, thereby raising the top opening of the shopping cart basket 1, so as to accommodate more extra-tall goods and make it more convenient for customers to move and stack more goods.

[0024] The two guardrails can be positioned together by the cross-engagement of the external hinge 311 and the internal hinge 321, so that the two sets of horizontal guardrails 31 and the two sets of vertical guardrails 32 can be folded on the outside and inside of the shopping cart basket 1 respectively, so that customers can selectively increase the height of the shopping cart according to their needs, making the shopping cart more practical.

[0025] The cart seat 2 has a push handle 21 fixedly installed on the top of one side. The shopping cart basket 1 is fixedly installed on the top of the cart seat 2. External hinges 311 are fixedly installed on the outer side of the two sets of longitudinal guardrails 31 and the outer edge of the top of the shopping cart basket 1. Internal hinges 321 are fixedly installed on the inner side of the horizontal guardrails 32 and the inner edge of the top of the shopping cart basket 1. The two guardrails can be positioned together by the cross-interlocking of the external hinges 311 and the internal hinges 321, so that the two sets of horizontal guardrails 31 and the two sets of longitudinal guardrails 32 can be folded on the outer and inner sides of the shopping cart basket 1 respectively, so that customers can selectively raise the height of the shopping cart according to their needs.

[0026] Two sets of longitudinal guardrails 31 have openings 41 near their ends at the top. The bottom of the push block 42 slides in the inner wall of the opening 41. The positioning spring 43 is fixedly installed on the inner wall of the corresponding opening 41 at the end away from the push block 42. The rotating block 5 has a corresponding insertion hole near the insertion rod 44. The insertion rod 44 extends through the inner wall of the opening 41 to the insertion hole at the end of the corresponding rotating block 5. After the raised guardrail 3 is extended vertically from the outside through the longitudinal guardrails 31 on both sides, the two sets of transverse guardrails 32 are extended vertically from the inside of the shopping cart basket 1. The four sets of rotating blocks 5 are rotated to connect the adjacent ends of the longitudinal guardrails 31 and the transverse guardrails 32. By pushing the push block 42 to squeeze the positioning spring 43, the insertion rod 44 can be inserted into the insertion hole at the end of the corresponding rotating block 5. This allows the ends of the two longitudinal guardrails 31 and the transverse guardrails 32 to be stably positioned together, thereby raising the top opening of the shopping cart basket 1.

[0027] Working principle: When a customer needs to raise the height of the shopping cart basket 1, the vertical guardrails 31 on both sides of the raised guardrail 3 can be unfolded from the outside to the vertical position. Then, the two sets of horizontal guardrails 32 can be unfolded from the inside of the shopping cart basket 1 to the outside to the vertical position. After rotating the four sets of rotating blocks 5 to fit the adjacent ends of the vertical guardrails 31 and the horizontal guardrails 32 together, the push block 42 in the positioning component 4 can be moved so that the insertion rod 44 can squeeze the positioning spring 43, so that the insertion rod 44 can be inserted into the insertion hole at the end of the corresponding rotating block 5. In this way, the ends of the two pairs of vertical guardrails 31 and horizontal guardrails 32 can be stably positioned together, thereby raising the top opening of the shopping cart basket 1, so as to accommodate more extra-tall goods and make it more convenient for customers to move around and stack more goods.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
