Second, technical characteristics
1. The assembly structure of the wrap angle assembly is simple and easy to use. The high strength and support of the steel frame folding container pillar are generally achieved through the wrap angle component. The chute locking type wrap angle component is not only easy to manufacture due to the assembled welding structure. And the sliding gap between the column and the wrap angle components can be controlled to the minimum (the wrap angle guide plate and the vertical plate can be welded closely to the column under the assembly precision), thereby improving the strength of the post supporting.

2. The column is complete, high strength, small sliding clearance, good stability The bottom supporting surface (pipe nozzle) is flat without slope (in order to rotate normally with an inclined surface), the nozzle contact surface is complete, and the lower end of the nozzle is pinned in the tube The inner wall of the mouth is welded; the upper end is connected with the sleeve, which not only enhances the strength of the nozzle, but also does not affect the folding function of the column due to the welding slag welding. Therefore, the sliding gap between the column and the wrap angle component can be reduced, thereby reducing The column's shaking, improve storage and transportation reliability.

3. Folding height is low, which can greatly improve the storage and transportation capacity. Because the strength and stability of the column can be ensured by increasing the thickness of the pipe and reducing the sliding gap of the column, the height of the package angle can be greatly reduced, thereby reducing the folding height. The general wrap angle is one-third of the height of the column. After practice, the wrap angle can be 1/4 to 1/6 of the height of the column, such as 1 m below the column height, and the wrap angle can be within 0.15~0.18 m. Ordinary transport vehicles can stack more than 10 layers of empty folding containers.

4. Combine with the cone stacking foot to ensure the reliability of storage and transportation The folding metal container stacking feet for general transport are “horse shoe” and “sleeve type”. The clearance after stacking is large and easy to shake, especially Multi-layered stacks are less reliable when shipped. In combination with the "cone-shaped" stacking feet, since the cones and cones are seated, the stacking can be performed more tightly without any gaps, thereby further enhancing the reliability of storage and transportation.

Third, the economic value of container production structure is compact, less consumables, light weight, and is expected to increase the overall logistics capacity of more than 50%. A multi-layer stacking unit made from a 50-pole tube can stack more than 3 tons of cargo and achieve safe transportation. Compared with wooden boxes or heavy steel frame containers, storage and transportation capacity can be increased by 50% to 100% (such as Chongqing Pan'an and Zhengzhou Nissan engine transport); also save a lot of packaging materials and packaging, distribution and other personnel and venues; energy saving and environmental protection It is also incalculable.
