[0027] The present utility model will be further described below in conjunction with specific embodiments:

[0028] A folding shopping cart with a reinforced bottom plate, as Figure 1 shown, the folding shopping cart described in this patent is made of plastic material, and it includes the folding box body 1 and the bottom plate 4 of the box described in this patent. In addition, a pull rod 7 is provided on the folding box body 1, and rollers 8 are provided at the bottom of the folding box body 1. The entire folding box body 1 is pulled by the pull rod 7, and the folding box body 1 is rolled by the rollers 8 to cooperate with the pull rod 7 to realize the movement of the shopping cart in this patent.

[0029] Specifically, in combination with Figure 2 , 3 shown, the folding box body 1 includes a plurality of box boards 11 connected in a surrounding manner, and a folding assembly 2 for sequentially stacking the plurality of box boards 11 is provided between the box boards 11. A bottom opening 3 is formed at the bottom of the folding box body 1. The bottom plate 4 of the box is used to be installed in the bottom opening 3, and a first connecting piece 5 is provided on the folding box body 1 at the bottom opening 3, and a second connecting piece 6 corresponding to the first connecting piece 5 is provided on the outer edge of the bottom plate 4 of the box.

[0030] As Figure 2 shown, in this patent, there are two box boards 11, and the two box boards 11 are respectively arranged front and back, and the folding assembly 2 is respectively connected left and right between the two box boards 11; the folding assembly 2 includes a first folding plate 21 and a second folding plate 22 which are rotatably connected, and the first folding plate 21 and the second folding plate 22 are respectively rotatably connected to the two box boards 11. As Figure 2 , 5As shown, the first folding plate 21, the second folding plate 22 and the box plate 11 are rotationally connected by means of hinges. At this time, there are two first folding plates 21 and two second folding plates 22 respectively, which are sequentially connected around the box plate 11 to form a square structure; when folding, the first folding plate 21 and the second folding plate 22 fold inward towards the inner sides of the two box plates 11 and fold between the two box plates 11, and the two box plates 11 are stacked front and back to form a planar whole. When opening, the first folding plate 21 and the second folding plate 22 open towards the outer ends of the two box plates 11 to form a square structure. At this time, an upper opening and a bottom opening 3 are respectively formed at the upper and lower ends of the folding box body 1, and the box bottom plate 4 is installed in the bottom opening 3.

[0031] The box bottom plate 4 can be directly inserted downward from the upper opening of the folding box body 1 into the folding box body 1 and then fixed in the bottom opening 3, or it can be directly rotationally connected to the bottom end of the box plate 11. It can be folded inward on one side of the box plate 11 when the folding box body 1 is folded, and at the same time, it can be opened outward and located in the bottom opening 3 when the folding box body 1 is opened. In order to facilitate the support of the box bottom plate 4, a support boss 12 for supporting the end of the box bottom plate 4 is provided on the remaining box plates 11; since there are two box plates 4 in this patent, the support boss 12 is provided on the other box plate 4 opposite to the box plate 4 rotatably connected with the box bottom plate 4, and is supported by the support boss 12 after the box plate 4 rotates.

[0032] In this embodiment, the first connecting member 5 includes a card slot provided on the folding box body 1, and the second connecting member 6 is a pin provided on the outer edge of the box bottom plate 4; the positions where the card slot and the pin are installed can be interchanged, and it can also realize the mutual fitting connection between the folding box body 1 and the box bottom plate 4. The first connecting member 5 and the second connecting member 6 have various forms, as long as the two are fixedly connected. It can adopt a snap or the pin form in this patent. Relatively speaking, the pin form is quicker to disassemble and install, and the snap structure is more stable as a whole after installation. By means of the first connecting member 5 and the second connecting member 6 that fixedly connect the box bottom plate 4 and the folding box body 1, when the folding structure in the folding box body 1 ages and causes the bottom opening 3 to become larger, the box bottom plate 4 can still be normally fixed in the bottom opening 3 and will not fall off due to the enlargement of the bottom opening 3, so that the folding shopping cart in this patent can be normally formed, thereby increasing the service life of the folding shopping cart.

[0033] Furthermore, inclined plane walls 61 are provided on both sides of the end of the pin. The inclined plane walls 61 are used to enable the pin to slide into the card slot faster through the inclined plane walls 61 when the pin is inserted into the card slot, so that the box bottom plate 5 does not need to be aligned during installation, facilitating the faster installation of the box bottom plate 4.

[0034] Further, a grasping through-hole 44 is also formed in the bottom plate 4 of the box for grasping the rotation of the bottom plate 4 of the box through the grasping through-hole 44. As Figure 4 shown, one end of the bottom plate 4 of the box is provided with a "U"-shaped opening, and the grasping through-hole 44 is formed in the opening. The grasping through-hole 44 is used to reduce the difficulty of disassembling the bottom plate 4 of the box and facilitate its rapid assembly.

[0035] Further, a boss portion 23 is provided at one end of the first folding plate 21 and the second folding plate 22 close to the bottom opening 3. The first connecting member 5 is provided on the boss portion 23. The edge of the bottom plate 4 of the box is lapped on the boss portion 23, and the second connecting member 6 is provided thereon. As Figure 5 shown, the boss portion 23 is trapezoidal and is integrally formed at the bottom of the first folding plate 21 and the second folding plate 22. Correspondingly, a groove 41 is provided on the bottom surface of the bottom plate 4 of the box. When the edge of the bottom plate 4 of the box is lapped on the boss portion 23, the boss portion 23 is located in the groove 41. The connection between the bottom plate 4 of the box and the folding box body 1 is positioned through the structures of the groove 41 and the boss portion 23 to make the connection between the two more stable.

[0036] As Figure 4 shown, a plurality of reinforcing ribs 42 are provided at the bottom of the bottom plate 4 of the box. In the middle of the bottom of the bottom plate 4 of the box, the plurality of reinforcing ribs 42 are connected to form a rhombic groove. The reinforcing ribs 42 are used to increase the support strength of the bottom plate 4 of the box. A trapezoidal groove is separated by the reinforcing ribs 42 on one side of the bottom plate 4 of the box close to the folding assembly 2. The shape of the trapezoidal groove is adapted to that of the boss portion 23, which is the groove 41. A second connecting member 6, that is, a snap pin, is integrally formed on the reinforcing rib 42 on the outer side of the groove 41. A support rib 43 connecting the second connecting member 6 and the other side wall of the groove 41 is further provided in the groove 41. The support rib 43 is used to increase the stability of the snap pin arrangement and prevent it from breaking easily.
