Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to a high-strength packaging box. Background Technology
[0002] Most packaging containers are made of paper materials (most commonly corrugated cardboard) through a folding process, and their side walls are usually fixed by natural adhesion after folding, glue bonding or nailing.
[0003] When traditional packaging containers are stacked for storage, the top bears significant pressure, often causing the side walls to deform from the inside out due to the inability to withstand external forces. In view of these shortcomings, a packaging box with higher structural strength is needed to overcome the weakness of traditional packaging boxes in terms of side wall deformation during stacking. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where, during stacked storage, the top is subjected to significant pressure, often causing the sidewalls to be unable to withstand external forces and easily deform from the inside out. This invention proposes a high-strength packaging box.

The rear plate 2 is directly connected to one side of the base plate 1, while the connecting paper strips 17 connect the bent parts, with their two sides connected to the rear plate 2 and the reinforcing plates 6 respectively, facilitating the inward bending of the reinforcing plates 6. Side baffles 4 are symmetrically arranged on both sides of the base plate 1, and a front baffle 3 is integrally formed on the other side.
[0028] Two locking blocks 5 are fixedly installed on one side of the back panel 2, while two locking slots 7 that cooperate with the locking blocks 5 are opened on one side of the reinforcing plate 6. This allows the reinforcing plate 6 to be securely locked onto the back panel 2 after folding, further improving the strength and stability of the packaging box.
[0029] Specifically, the reinforcing plate 6 is folded inwards via the connecting paper strip 17, so that one end of it abuts against the base plate 1, and the clip 5 is clipped into the slot 7, thereby completing the folding of the back side.
[0030] The front baffle 3 includes a U-shaped blocking frame 31 and a fixed U-shaped plate 32. The fixed U-shaped plate 32 is connected to one side of the base plate 1, while the two ends of the blocking U-shaped frame 31 are respectively connected to the two ends of the fixed U-shaped plate 32. Secondary support plates 34 are connected to the inner walls on both sides of the fixed U-shaped plate 32, and a primary support plate 33 is connected to the top of the secondary support plate 34. Meanwhile, a primary support plate 35 is connected to the inner wall at the bottom of the fixed U-shaped plate 32, and a secondary support plate 36 is connected to the top of the primary support plate 35.

[0032] Specifically, the second auxiliary support plate 34 is folded inward so that it is located on the back of the fixed U-shaped plate 32, the first auxiliary support plate 33 is folded downward so that one end of it abuts against the bottom plate 1 for support, the first main support plate 35 is folded inward so that one end of it abuts against the bottom plate 1 for support, and the second main support plate 36 is bent into a state parallel to the bottom plate 1 and fits against it for support. Then the U-shaped frame 31 is folded inward to cover the first auxiliary support plate 33, the second auxiliary support plate 34, the first main support plate 35, etc., and the first clip plate 8 is clipped into the first clip hole 10 to fix it, thus completing the folding of the front.
[0033] The side panel 4 includes a reinforcing frame 46, a bottom support plate 43, and two fixed cardboard pieces 41. The two fixed cardboard pieces 41 are connected to both ends of one side of the bottom plate 1, and the two ends of the reinforcing frame 46 are connected to the tops of the two fixed cardboard pieces 41. A third auxiliary support plate 42 is connected to one side of the fixed cardboard pieces 41, while the bottom support plate 43 is connected to one side of the bottom plate 1, with its two sides connected to the sides of the two fixed cardboard pieces 41 that are close to each other. A third main support plate 44 is connected to the top of the bottom support plate 43, and a fourth main support plate 45 is connected to the top of the third main support plate 44.
[0034] Similarly, two second-order card plates 9 are connected to the top of the reinforcing frame 46, while two second-order card holes 11 that cooperate with the second-order card plates 9 are opened on both sides of the top of the bottom plate 1.
[0035] Specifically, the third auxiliary support plate 42 is folded inward so that it is located on the back of the fixed cardboard 41. The third main support plate 44 is also folded inward so that one end of it abuts against the bottom plate 1. The fourth main support plate 45 is also folded in a state parallel to the bottom plate 1 and fits against it to provide support. Then, the reinforcing frame 46 is folded inward to cover the third auxiliary support plate 42, the third main support plate 44, and other parts. The second card plate 9 is then inserted into the second card hole 11 to fix it in place, thus completing the side folding.
[0036] By folding, its thickness is increased accordingly, and it gains supporting capacity, thereby enhancing its load-bearing capacity and resistance to deformation.
[0037] This application can be used in the field of packaging, or in other fields applicable to this application.
