[0002] Storage and transportation boxes are widely used in the packaging, storage and transportation of items, and are mainly steel or composite material packaging boxes. During transportation, when necessary, nitrogen or dry air can be filled into the inner cavity of the storage and transportation box to protect the contents. The storage and transportation boxes are long-term exposed to harsh environments such as high salt fog, high temperature and high humidity, which are likely to cause corrosion and damage to the storage and transportation boxes, and need to be maintained every year, resulting in high costs, poor economy and reliability.

[0003] In the existing technical solutions, most storage and transportation boxes are made of a steel structure frame + an outer steel skin, and the buckle is used for positioning and fastening at the box joint, and the inner volume of the box is relatively small. There are a small number of composite material storage and transportation boxes on the market, with poor product consistency and poor stacking conductivity.

[0004] The following deficiencies exist in the prior art:

[0005] 1. The space utilization rate in the height direction of traditional storage and transportation boxes is low, and the capacity is small;

[0006] 2. Traditional steel material storage and transportation boxes are heavy in mass, easy to corrode, and poor in waterproof and gas-proof performance under outdoor storage and transportation conditions;

[0007] 3. The contact friction coefficient between traditional steel storage and transportation boxes and steel floors such as ships and carriages is small, and sliding and bumping are likely to occur;

[0008] 4. The stacking conductivity of traditional composite material storage and transportation boxes is not good, and static electricity accumulation is likely to occur, affecting the safety of the items inside;

[0009] 5. Traditional composite material storage and transportation boxes have low production efficiency and poor product consistency;

[0010] 6. For traditional storage and transportation boxes, only the outer edge alignment method is used for box closing, and it is difficult to position the box by crane;

[0011] 7. Traditional storage and transportation boxes adopt a frame + skin structure, with low local strength and poor corner drop performance. Content of the Utility Model
