Description

Technical Field

[0001] The invention relates to the technical field of door and window transportation, in particular to a packaging structure for door and window transportation. Background Art

[0002] After the doors and windows are produced, they need to be transported. Especially when transporting over long distances, in order to prevent the goods from being damaged, deformed, and other problems during the process, the doors and windows need to be protectively packaged. Existing packaging technologies for doors and windows include wrapping or applying a film on the aluminum alloy frame to prevent scratches; to prevent the glass from being unable to withstand long-distance bumps, it also needs to be removed separately and transported together, and then the frame and glass are assembled after arriving at the destination. The above traditional transportation methods cannot meet the current transportation needs of integrated doors and windows, and often there are no special tools to seal and assemble the frame and glass after delivery to the destination. Therefore, in response to the above problems, some manufacturers use a box structure to package and transport doors and windows, and use disposable vibration-damping protective foam or film structures in the box to reduce the damage to the goods caused by vibration during long-distance transportation. However, if the size of the box does not match that of the doors and windows, the doors and windows may easily shake and become damaged inside the box. Filling the box with protective items also makes the operation more complicated. If a corresponding packaging box is specially customized for each type of door and window, the packaging cost will increase dramatically. Moreover, the above packaging methods can only be used once, which will cause serious environmental pressure.
