Description

Technical Field

[0001] This utility model relates to the field of paper packaging box technology, and in particular to a paper packaging box for logistics transportation. Background Technology

[0002] In logistics transportation, goods are often transported using paper packaging boxes. Currently, most paper packaging boxes are made of corrugated cardboard and are easy to assemble. However, existing paper packaging boxes generally have the following defects in logistics transportation: the internal support structure of the box is not effective, and the pressure of the upper box when stacked can easily cause the top of the lower box to collapse, especially when transporting heavy objects or stacking multiple layers; the lids lack an interlocking structure, and vibration during transportation can easily cause the lids to shift, resulting in the box opening or the goods being exposed; the bottom plate is prone to deformation under long-term load, affecting the structural stability of the box.

[0003] Therefore, we propose a paper packaging box for logistics transportation to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a paper packaging box for logistics transportation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A paper packaging box for logistics transportation includes a main box body, a short cover plate, a long cover plate, a short bottom plate, and a long bottom plate. The main box body is provided with a support member, which includes a hard plate for laying flat on the bottom of the box and vertical double-layer plates distributed around the hard plate. The double-layer plates are in close contact with the side walls of the main box body, and the top of the double-layer plates supports either the short cover plate or the long cover plate. The surface of the long cover plate is provided with a first protrusion, which is used to fit into the groove between the short cover plate and the double-layer plates. The hard plate is provided with a second protrusion in the middle, and the raised surface of the second protrusion is sandwiched between the two short bottom plates. A vertical support frame is provided under the short cover plate, and the lower edge of the support frame is used to insert into the groove surface of the second protrusion.

[0007] In a further embodiment, the width of the slit between the side of the short cover plate and the double-layer plate on the long side of the hard plate is 1-3 mm wider than the width of the first convex strip.

[0008] In a further embodiment, there are two double-layer plates symmetrically distributed on each long side of the rigid plate about the two sides of the second protrusion, and a gap of the same width as the second protrusion is provided between the two double-layer plates.

[0009] In a further embodiment, the height of the double-layer plate on the long side of the rigid plate is greater than the height of the double-layer plate on the short side of the rigid plate, and the height difference is equal to the thickness of the short cover plate.

[0010] In a further embodiment, the double-layer plate adopts a hollow spiral structure.

[0011] In a further embodiment, the protrusion height of the second protrusion is equal to the thickness of the short base plate.

[0012] In a further embodiment, the support frame adopts a portal frame structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a hard flat plate laid on the bottom of the box to reduce the problem of the bottom plate easily deforming under long-term load. The short bottom plate is limited by the two protruding strips to prevent the short bottom plate from shifting and deforming, which would affect the stability of the box structure. The vertical double-layer plate is set close to the side wall of the main box to form a U-shaped support frame to distribute the stacking pressure. The top of the double-layer plate directly supports the cover plate to prevent the top cover from collapsing. In addition, the hollow inside of the double-layer plate can also play a certain role in buffering and resisting pressure on the side of the box.

[0015] The support frame of this utility model is inserted into the groove of the second protrusion to form a vertical load-bearing column, which enhances the overall rigidity of the box. The protrusion of the long cover plate is inserted into the groove between the short cover plate and the double-layer plate to achieve lateral limitation. The cover plates are interlocked to prevent displacement and prevent transportation vibration from causing the box to open or the goods to be exposed. Attached Figure Description

[0028] Please see Figure 1-8A paper packaging box for logistics transportation includes a main box body 1, a short cover plate 2, a long cover plate 3, a short bottom plate 4, and a long bottom plate 5. The main box body 1 is a rectangular box structure with four upright side walls. The short cover plates 2 are symmetrically arranged on the upper edges of the two short sides of the main box body 1, and the short bottom plates 4 are symmetrically arranged on the lower edges of the two short sides of the main box body 1. The long cover plates 3 are symmetrically arranged on the upper edges of the two long sides of the main box body 1, and the long bottom plates 5 are symmetrically arranged on the lower edges of the two long sides of the main box body 1. A support frame 21 is provided on the side of the short cover plate 2 away from the main box body 1. The support frame 21 adopts a door-shaped structure, consisting of a horizontal beam and two symmetrical vertical bars, with a gap in the middle to facilitate the placement of goods. During assembly, the support frame 21 is folded at a 90° angle with the short cover plate 2. The main box body 1, short cover plate 2, long cover plate 3, short bottom plate 4, long bottom plate 5, and support frame 21 are all integrally die-cut from corrugated paper.

[0029] The main body 1 is equipped with a support component, which includes a rigid flat plate 6 and a double-layer plate 7. The rigid flat plate 6 and the double-layer plate 7 are formed by integrally die-cutting and bending cardboard. The rigid flat plate 6 is laid flat on the bottom of the box, and the middle part is bent four times to form a longitudinal protrusion 61. The height of the protrusion is equal to the thickness of the short bottom plate 4. After the short bottom plate 4 is closed, the protruding surface of the second protrusion 61 is sandwiched in the middle, and the grooved surface of the second protrusion 61 faces inward to facilitate the insertion of the lower edge of the support frame 21. The short bottom plate 4 is flush with the second protrusion 61, and the double-layer plate 7 runs along the four sides of the rigid flat plate 6. The double-layered panels 7 are distributed and closely attached to the inner wall of the main box 1. They are divided into two groups: one group located on the long side of the hard plate 6 and the other group located on the short side of the hard plate 6. The double-layered panels 7 on the long side are taller and support the long cover plate 3 on top. The double-layered panels 7 on the short side are shorter and support the short cover plate 2 on top. There are two double-layered panels 7 on each long side, symmetrical about the second protrusion 61, with a spacing equal to the width of the second protrusion 61. The double-layered panels 7 are formed into a rectangular hollow section by four bends, which not only reduces weight but also provides a pressure-resistant cushioning effect on the sides of the box.

[0030] The surface of the long cover plate 3 is bent four times to form a protrusion 31. The protrusion 31 protrudes downward from the long cover plate 3. The protrusion 31 is used to fit into the slot between the short cover plate 2 and the double-layer plate 7. The specific slot width is 1-3mm larger than the protrusion 31 to facilitate the insertion of the protrusion 31 and form an interlocking of the cover plates.
