Description

Technical Field

[0001] This utility model belongs to the field of packaging structure technology, specifically relating to a reusable modular combination outer packaging structure. Background Technology

[0002] Currently, the mainstream packaging forms on the market are corrugated cardboard boxes and plastic pre-formed packaging. However, traditional cardboard boxes have many drawbacks: poor durability and strength, making them susceptible to water, moisture, and insect infestation during transportation and storage, leading to deformation and damage that threatens the safety of the contents; and goods are easily damaged by handling and squeezing during logistics transportation. Furthermore, cardboard boxes are mostly for single use, with low recycling rates, and their production process consumes a large amount of trees, water resources, and energy. While existing plastic pre-formed packaging has certain strength advantages, its shape and size are fixed after injection molding, making it difficult to adjust according to actual needs and limiting its reuse scenarios.

[0003] Given the numerous limitations of corrugated cardboard boxes and plastic pre-packaged packaging in practical applications, which make it difficult to meet the requirements of modern logistics for packaging materials in terms of strength, durability, environmental friendliness, and recyclability, there is an urgent need for a new packaging structure to compensate for these deficiencies.

Construct multiple main frames using Module 2 A2-1, Module 2 B2-2, Module 2 C2-3, and Module 2 D2-4 in the same way. By using the interlocking posts and interlocking holes, the top frame, multiple main frames, and bottom frame 7 are spliced ​​together to form the main frame. The bottom plate and top plate are connected to the main frame through fixing strips to form a stable spatial structure.

[0056] When disassembling module one or module two, open the side plate with the longest length in module one or module two, and then pull out the fixing pin 6-5 and the connecting shaft 6-1 of the rotating connector 6 in sequence to disassemble module one or module two. This utility model can flexibly adjust its size and shape, and can adapt to different cargo requirements by deforming the top frame, multiple main frames, bottom frame 7, bottom plate, and top plate, or by increasing or decreasing the number of main frame layers or modules.
