Through the structural arrangement of the above-mentioned honeycomb connecting strips and the gaps in the skeleton board, the insertion of the bed head and the bed body is realized. Not only is it convenient to plug in, but also the connection after plugging is very firm.

The corrugated cardboard folding splicing bed of the present invention boldly adopts the honeycomb structure to construct the bed, and breaks the tradition of overall prefabrication of the honeycomb board, and adopts the folded honeycomb strips of the corrugated cardboard to be spliced by consumers at the site of use. The scale of this kind of honeycomb strip is much larger than the scale of a honeycomb unit on a conventional honeycomb board, but it is also unreasonable to use corrugated cardboard with low strength in traditional concepts. However, the practice of the present invention has proved that it can fully meet the special requirements of people rolling repeatedly during sleep and jumping while standing on the bed, and can be repeatedly disassembled and used for a long time. The head of the bed of the present invention is also spliced with corrugated cardboard or folded elements. The present invention breaks away the traditional idea that people can build beds only by using strong wooden boards, and realizes the dream of using corrugated boards in the production of beds to save precious timber resources by folding and splicing corrugated boards.

The invention is suitable for large-scale factory mechanized production, is convenient for packaging and transportation, is suitable for use, and has broad market promotion prospects.
