[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides a lightweight, foldable storage and transportation box through improvements. The technical solution of this utility model is as follows:

[0027] like Figures 1-6 As shown, a lightweight foldable storage and transportation box includes a base plate 1 with a U-shaped cross-section. Two side plates 2 are rotatably connected to the base plate 1. When in use, the side plates 2 are perpendicular to the base plate 1, and when stored, the side plates 2 are parallel to the base plate 1. The key feature is that each of the two side plates 2 adopts a standardized hinge structure to hinge two side plates 3 respectively, ensuring that the side plates 3 can maintain a stable coplanar state with the side plates 2 when unfolded. The base plate 1, side plates 1 and 2, side plates 2 and 3, connecting frame 4, support plate 5, and top cover 10 in the device are all made of biodegradable polymer materials, and also include:

[0028] The connecting frame 4 is rotatably connected to two side plates 3. The top cover 10 is smoothly slidably connected in the sliding groove 8 preset in the connecting frame 4 through two sliding strips 9. The sliding groove 8 is provided with a guide slot to ensure that the top cover 10 does not jam or shift during the sliding process. Two support plates 5 are rotatably connected to the bottom plate 1. During installation, firstly, the side plate 2 is rotated to be perpendicular to the bottom plate 1, and then the side plate 3 is rotated 180° so that it is on the same vertical plane as the side plate 2. Then, the support plate 5 is flipped up so that its bottom is perpendicular to the bottom plate 1 and its two sides are respectively against the side plate 2 and the side plate 3. The limiting block 6 is embedded in the slot 7. The limiting block 6 adopts an elastic locking structure design. Its size and shape match the slot 7 opened on the connecting frame 4. When the support plate 5 is rotated to be perpendicular to the bottom plate 1, the limiting block 6 can be firmly locked into the slot 7 to ensure that the device remains stable during use, thereby completing the installation of the device. This allows the device to be quickly folded and unfolded, improving its practicality.

[0029] Furthermore, such as Figures 1-6 As shown, two limiting blocks 6 are fixedly connected to the two support plates 5 respectively. The limiting blocks 6 are perpendicular to the top of the support plates 5. Two slots 7 are opened on the connecting frame 4. The two slots 7 are symmetrical about the base plate 1. The two slots 7 are respectively adapted to the two limiting blocks 6.

[0030] Furthermore, such as Figures 1-6 As shown, two sliding grooves 8 are provided on the connecting frame 4, and two sliding strips 9 are slidably connected in the two sliding grooves 8 respectively. The two sliding strips 9 are fixedly connected to the top cover 10, and the two sliding strips 9 are symmetrical about the top cover 10.

[0031] Furthermore, such as Figures 1-6 As shown, a handle 11 is fixedly connected to the top cover 10, which makes the device easy to carry and use.

[0032] Furthermore, such as Figures 1-6 As shown, two threaded rods 12 are provided on the connecting frame 4. These two threaded rods 12 are threadedly connected to the threaded holes 13 pre-drilled on the top cover 10, thereby achieving precise restriction of the position of the top cover 10 and preventing the top cover 10 from sliding when the device moves, which would affect its use.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, four pins 14 are fixedly installed on the connecting frame 4. Each pin 14 is provided with an elastic protrusion, which is designed to be tightly engaged with the four slots 15 correspondingly opened on the base plate 1, so as to fix the base plate 1 and the connecting frame 4 after folding, making it easy to move and store. The base plate 1 has four slots 15, and the four pins 14 are respectively adapted to the four slots 15.

[0034] The specific working method is as follows: When the device needs to be stored, push the limiting block 6 so that the limiting block 6 passes through the slot 7 and separates from the connecting frame 4. Then push the support plate 5 to rotate inward so that one side of the support plate 5 is in contact with the top of the bottom plate 1. Then push the hinge of the side plate 1 2 and the side plate 2 3 inward so that the side plate 1 2 and the side plate 2 3 rotate. One side of the side plate 1 2 is in contact with the top of the support plate 5, and one side of the side plate 2 3 is in contact with the other side of the side plate 1 2. At this time, the bottom of the top cover 10 is in contact with the other side of the side plate 2 3, and the pin 14 is inserted into the slot 15, thereby completing the folding of the device. The folded box structure is locked by the cooperation of the pin 14 and the slot 15 to ensure that the folded structure is stable and does not fall apart, and is easy to move and store.

[0035] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
