Technical Field
[0001] The utility model relates to the field of transfer boxes, in particular to a foldable and sealed EPP box body for transportation. Background Art
[0002] Most of the existing agricultural product transfer boxes are integrally formed and occupy a relatively large space when not in use. Some of them have the function of folding. Generally, the side plates, bottom plates and cover plates cannot be folded together completely. Even if a few box bodies can be folded together completely, there are relatively large gaps between the side plates, bottom plates and cover plates after folding, which cannot provide mutual support and are easily damaged by extrusion.
[0003] Therefore, it is necessary to provide a foldable and sealed EPP box body for transportation to solve the above technical problems. Summary of the Utility Model

Detailed implementation manners
[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] Please refer to Figures 1 to 6 , a foldable and airtight EPP box for transportation. The box mainly consists of a box bottom plate 1. Four sides of the box bottom plate 1 are ingeniously provided with connecting parts 2 extending upward. The front side plate 4, the left side plate 5, the rear side plate 6, and the right side plate 7 are sequentially connected to these connecting parts through the first hinge shaft 3. It is worth mentioning that the front side plate 4 and the right side plate 7 have the same size, and the left side plate 5 and the right side plate 7 also have the same size. This symmetrical design not only improves the aesthetics of the box but also makes the folding process extremely simple. The front side plate 4, the left side plate 5, the rear side plate 6, the right side plate 7, and the box bottom plate 1 are all made of EPP material.
[0023] At the inner top end of the connecting part 2, a first rounded corner 8 is carefully designed, and at the inner bottom end of the front side plate, the left side plate 5, the rear side plate 6, and the right side plate 7, a second rounded corner 9 is provided. The design of these two rounded corners not only improves the contact smoothness between the plates but also keeps concentric with the first hinge shaft 3, ensuring the smoothness of the plates during folding and unfolding.
[0024] During the folding process, first, by rotating the left side plate 5 and the right side plate 7, they are rotated along the first hinge shaft 3 to be perpendicular to the box bottom plate 1. At this time, the first plane 10 is closely attached to the second plane 11, and the third plane 12 is also in contact with the fourth plane 13, forming a stable support structure. When these two side plates continue to fold inward until they contact the box bottom plate 1, they complete the folding process.
[0025] Next, the front side plate 4 and the rear side plate 6 also follow the same folding principle. They are rotated to the vertical position through the first hinge shaft 3 and then folded inward until they contact the already folded side plates, completing the main folding of the box.
[0026] Finally, the cover plates 14 at the top ends of the front side plate 4 and the rear side plate 6 start to play a role. They are connected to the mounting seats 20 through the third hinge shafts 21, and the mounting seats 20 are connected to the front side plate 4 and the rear side plate 6 through the second hinge shafts 19. During the folding process, the cover plates 14 rotate along the third hinge shafts 21, and at the same time, the mounting seats 20 rotate relative to the front side plate 4 and the rear side plate 6 along the second hinge shafts 19, finally making the cover plates 14 closely attached to the front side plate 4 and the rear side plate 6, achieving the complete folding of the box.
[0027] To enhance the stability and protection performance of the box body, blocking portions 15 that are bent at a 90-degree angle towards the inner side of the box body are designed at both ends of the front side plate 4 and the rear side plate 6, while mating grooves 16 that cooperate with the blocking portions 15 are provided at both ends of the left side plate 5 and the right side plate 7. This design not only limits the maximum unfolding angle of the plate members, but also further enhances the stability between the plate members through the tight fit between the protrusions 17 in the mating grooves 16 and the grooves 18 on the inner side of the blocking portions 15.
[0028] When the box body is fully folded, the blocking portions 15 are in close contact with the top of the connecting portions 2 on the left and right sides of the box body, and the front side plate 4 and the rear side plate 6 are respectively in close contact with the corresponding cover plates 14, forming a compact and stable structure. This design is not only convenient for storage and transportation, but also demonstrates excellent performance in protecting the box body and the internal items.
[0029] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
