DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Embodiment: Refer to Figures 1-5 , a packaging carton with a partition backing plate in the present utility model, includes a main box body 1. Several connecting side plates 2 are connected to both the upper and lower ends of the main box body 1. The connecting side plates 2 are divided into long side plates and short side plates. Two long side plates and two short side plates are symmetrically arranged at both the upper and lower ends of the main box body 1. Two double-layer connecting plate layers 3 are equidistantly arranged on the long side plates at the upper end of the main box body 1. A backing plate layer 4 is arranged on the inner side wall of the main box body 1. The backing plate layer 4 is hinged and attached to the inner side wall of the main box body 1. Through the arrangement of the backing plate layer 4, it is convenient to better block the gap formed by the assembly of the connecting side plates 2 and provide buffering for the stored items. A long partition 5 is arranged at the side end of the backing plate layer 4. Four short partitions 7 are symmetrically arranged on both sides of the long partition 5. When the backing plate layer 4 is attached to the side wall of the main box body 1, the long partition 5 and the short partitions 7 are folded and attached to the backing plate layer 4. Through the arrangement of the folding structure, the folding carton can be better stored, thereby reducing the storage position for carton storage. First convex blocks are convexly arranged on the short partitions 7, and two first card slots 6 for clamping the first convex blocks are equidistantly opened on the long partition 5. Through the arrangement of the first card slots 6 and the first convex blocks, the short partitions 7 can be better fixed on the long partition 5, so that the short partitions 7 can stand stably, thereby preventing the mutual collision of items.

[0021] In the present utility model, two second card slots 8 are symmetrically opened on the side wall of the main box body 1. Second convex blocks for clamping the second card slots 8 are symmetrically convexly arranged on both sides of the long partition 5. Through the arrangement of the second card slots 8 and the second convex blocks, the long partition 5 can be better erected and supported, preventing the items sub-packed in the main box body 1 from collapsing due to the inclination of the long partition 5, resulting in the rolling and mutual collision of the items. A foam seat 9 is horizontally arranged in the middle layer of the main box body 1. The double-layer connecting plate layer 3 is composed of a first connecting plate 10 and a second connecting plate 11. The first connecting plates 10 are glued to the long side plates at the side ends, and the second connecting plates 11 are unfolded and fixed on the foam seat 9. Through the arrangement of the double-layer connecting plate layer 3, the upper storage space can be better divided, so as to better independently pack each product. Third card slots 12 for clamping the long partition 5 and the short partitions 7 are opened on the lower bottom surface of the foam seat 9. A vertical partition 14 is arranged on the top surface of the foam seat 9. Limiting convex blocks 13 for clamping the second connecting plates 11 are symmetrically arranged on both sides of the vertical partition 14. Through the arrangement of the foam seat 9, while separating the upper and lower compartments, the short partition 5 and the long partition 7 below the foam seat 9 can be stably limited, and the second connecting plates 11 can be fixed by the limiting convex blocks 13.

[0022] Working principle: When the utility model is used, first fold the connecting side panel 2 at the bottom of the main box body 1 and abut it horizontally, and glue the double-layer connecting board layer 3 to the connecting side panel 2, then flip the pad layer 4 and lay it flat on the horizontally folded connecting side panel 2, then flip the long partition 7 on the pad layer 4 vertically so that the second protrusion on the long partition 7 is inserted into the second slot 8, then flip the short partition 5 vertically so that the first protrusion on the short partition 5 is inserted into the first slot 6, then put the product in the gap formed by the short partition 5 and the long partition 7, then place and install the foam seat 9 on the short partition 5 and the long partition 7. When placing it, make the third slot 12 at the lower end of the foam seat 9 abut and fix with the short partition 5 and the long partition 7, then unfold the double-layer connecting board layer 3, and fold the upper connecting side panel 2 to make the second connecting board 11 unfold and insert it into the limiting protrusion 13, and now the unfolding and use of the packaging carton is completed.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
