Description

Technical Field

[0001] The invention patent relates to the technical field of wooden pallets, and specifically, to a foldable and disassembled wooden pallet box. Background Art

[0002] Generally speaking, wooden pallet boxes refer to large box-shaped objects made of wooden boards that are mainly used for wooden pallet transportation. This kind of wooden pallet box is not only easy to store and transport goods, but also has the advantage of being able to protect the goods inside, so it is widely used.

[0003] At present, there are three main types of packaging boxes that are widely used: traditional wooden boxes, panel boxes and assembled plywood boxes. Most traditional wooden boxes are disposable, which causes a great waste of resources. In addition, the panels of traditional wooden boxes are nailed together, which is difficult to disassemble. During transportation, they must be transported in full boxes, which takes up a huge amount of space, has low space utilization, and has high logistics costs. Although wooden pallet panel boxes can be folded into a flat plate during transportation to save space, it is not easy to replace damaged panel boards, and generally the entire frame needs to be replaced. Assembled plywood boxes can also be folded into a flat plate for transportation, and a single damaged panel can be replaced, but the disassembly and assembly of this type of container is cumbersome, time-consuming, and requires special tools, which is inefficient. During the disassembly and assembly process, due to the material of the wood, it is easy to be damaged, which increases the cost. Summary of the invention

[0004] The object of the present invention is to provide a foldable and disassembled wooden pallet box, which is provided with upper and lower plate folding frames, rotating side plates, folding side frames and upper and lower support plates, and is connected by multiple detachable bolts on the plate surfaces to achieve rapid installation, disassembly and fixation of the overall structure. When each plate surface is disassembled and placed separately, it can also be quickly retracted and unfolded, which is convenient for storage and transportation, avoiding the problem that most traditional wooden boxes are disposable, which causes a huge waste of resources, and the problem that the box boards of traditional wooden boxes are difficult to disassemble because they are nailed together.
