[0033] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —14:

[0034] This utility model provides a folding shopping cart, which includes a box body, a pull rod 1, and casters 2. The box body includes a bottom plate 3, a front panel 4, a back panel 5, and foldable left and right side panels. Each of the left and right side panels includes a foldable first side panel 6 and a second side panel 7. The first side panels 6 and the second side panels 7 are locked by a first locking structure. The two first side panels 6 are rotatably connected to the two sides of the back panel 5, and the two second side panels 7 are rotatably connected to the two sides of the front panel 4. One end of the bottom plate 3 is connected to the front panel. The lower end of panel 4 is rotatably connected to the back panel 5, and the other end is supported on the lower support platform 8 of the back panel 5. A partition 9 is provided above the bottom plate 3. One end of the partition 9 is rotatably connected to the panel 4, and the other end is supported on the upper support platform 10 of the back panel 5. The partition 9 divides the inner cavity of the box into an upper cavity 11 and a lower cavity 12. A window 13 is provided at the lower part of the panel 4 corresponding to the position of the lower cavity 12. A window plate 14 is provided at the window 13. The window plate 14 and the panel 4 can be opened and closed and locked by a second locking structure. It should be noted that one end of the bottom plate 3 and the partition 9 of this utility model can be rotatably connected to the back panel 5. Correspondingly, the other end of the bottom plate 3 and the partition 9 is supported on the corresponding lower support platform and upper support platform on the panel 4.

[0035] As can be seen from the above, this utility model divides the internal cavity of the box into an upper cavity 11 and a lower cavity 12 through the partition 9, which facilitates the classification and storage of items inside the cavity and improves space utilization. In addition, an openable window 14 is provided on the panel 4 corresponding to the lower cavity 12, which allows for independent retrieval and placement of items in the upper cavity 11 and the lower cavity 12. Specifically, items in the upper cavity 11 are retrieved and placed through the opening at the top of the box, and items in the lower cavity 12 are retrieved and placed through the window 13. After retrieval and placement are completed, the window 14 is locked to the panel 4 by a locking structure.

[0036] As a foldable shopping cart, when folding, the bottom plate 3 and the partition 9 are rotated toward the inner wall of the panel 4 or the inner wall of the back plate 5, pushing the panel 4 toward the back plate 5. At this time, the first side plate 6 and the second side plate 7 begin to fold until the panel 4 and the back plate 5 come together.

[0037] When unfolded, push panel 4 to move away from back panel 5, then lower bottom plate 3 and partition 9, and lock first side plate 6 and second side plate 7 through first locking structure.

[0038] When lever 1 is a telescopic lever, it retracts when folded and extends when unfolded.

[0039] Specifically, the first side panel 6 and the second side panel 7 can be folded and connected by hinges on their adjacent sides or by flexible components. Similarly, the first side panel and the rear side panel, the second side panel and the front side panel, and the partition and bottom plate and the panel are also connected by hinges or flexible components. Furthermore, the window panel and the panel can also be connected by hinges or flexible components. The flexible components can refer to rubber or fabric, etc. The flexible components are fixed to the various parts by fasteners, stitching, or one-piece molding.

[0040] As described above, the window panel 14 and the panel 4 are connected in an openable manner. In this embodiment, the lower end of the window panel 14 is rotatably connected to the lower edge of the window 13 on the panel 4, and the corresponding locking structure is located above the window panel 14.

[0041] Furthermore, the second locking structure includes a slide rail 15 located on the window panel 14, within which a sliding buckle 16 is slidably disposed. The sliding buckle 16 has elastic latches 17 that can engage with the upper and lower surfaces of the slide rail 15. When locking the window panel 14 and the panel 4, one end of the sliding buckle 16 slides into the inner side of the panel 4 to achieve locking. The elastic latches 17 prevent the window panel 14 from accidentally opening due to the sliding buckle 16 becoming loose.

[0042] It should be noted that, in this invention, a flip-up cover plate 18 is rotatably connected to the top of the panel 4, and the free end of the cover plate 18 overlaps the top edge of the back plate 5. The cover plate 18 can achieve a top sealing function.

[0043] Specifically, the flip-out capability is achieved through the following structure: the top of the panel 4 is provided with at least one groove 19, and vertical strip holes 20 are provided on both sides of the groove 19. The cover plate 18 is provided with an opening with a mounting hole at the corresponding position. The upper rotating shaft 21 and the lower rotating shaft 22 are arranged in parallel and fixed by the connecting block 23. Their two ends are respectively inserted into the mounting hole and the vertical strip hole 20 to form a flip-out connection structure.

[0044] In order to achieve positioning between the left side panel, the right side panel and the back panel 5, the back panel 5 is provided with rotating buckles 24 on both sides. When the left side panel and the right side panel are unfolded, the rotating buckles 24 are engaged in the slots of the first side panel 6.

[0045] Furthermore, the first locking structure of this utility model includes a sliding track 25 located at the upper edge of the first side plate 6 and the second side plate 7. An n-shaped slider 26 is provided on the first side plate 6 or the second side plate 7. The locking or unlocking of the first side plate 6 and the second side plate 7 is achieved by the movement of the n-shaped slider 26 along the sliding track 25. The rigidity between the first side plate 6 and the second side plate 7 is increased by the n-shaped slider 26.

[0046] In addition, the first locking structure may also employ a first lock integrated on the first side plate 6 and a second lock integrated on the second side plate 7, wherein the first lock and the second lock are connected to each other after the first side plate 6 and the second side plate 7 are unfolded.

[0047] This utility model also includes a lower insert plate 27 extending inward from the lower ends of the first side plate 6 and the second side plate 7. The lower insert plate 27 is provided with a lower insertion hole, and the bottom plate 3 is provided with a lower protrusion at a corresponding position that can be inserted into the lower insertion hole. Through the connection between the bottom plate 3 and the first side plate 6 and the second side plate 7, as well as the structure of the n-shaped sliding member 26 and the sliding track 25, the lower and upper ends of the first side plate 6 and the second side plate 7 can be locked, ensuring that the box will not deform during use and further improving the rigidity of the box.

[0048] The present invention also provides an upper insert plate 28 extending into the middle of the first side plate 6 and the second side plate 7. The upper insert plate 28 is provided with an upper insertion hole, and the partition plate 9 is provided with an upper protrusion that can be inserted into the upper insertion hole at a corresponding position, thereby further improving the rigidity of the box.

[0049] In addition, to facilitate lifting and placing this folding shopping cart, the present invention provides gripper grooves 29 at the upper ends of the first side plate 6 and the second side plate 7 for easy gripping.

[0050] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
