Description

Technical Field

[0001] The utility model relates to the field of equipment packaging, in particular to an adjustable steel-wood packaging box structure. Background Art

[0002] The steel-wood structure packaging box is made of channel steel and wooden planks to make the base, wooden planks and planks to make the side panels / end panels / cover panels, and then the equipment is loaded into and fixed to the base. The side panels, end panels and cover panels are assembled to form an integral packaging box to meet the needs of equipment protection and transportation.

[0003] Traditional wooden box production is to assemble the base with wooden sleepers and wooden boards, and the side panels, end panels and cover panels are assembled with wooden strips and wooden boards.
