Description

Technical Field

[0001] The present invention belongs to the technical field of cardboard furniture, and particularly relates to a corrugated cardboard component and a foldable children's bed including the corrugated cardboard component. Background Art

[0002] At present, most children's furniture is still manufactured using ordinary boards. There are many types of boards, including density boards (fiber boards), blockboards (big core boards), finger joint boards, particle boards (chipboards, solid wood particle boards), fireproof boards, ecological boards (melamine boards), solid wood boards, etc. Different types of boards will inevitably use volatile raw materials such as glue. However, children are more sensitive, and volatile raw materials are likely to cause problems to children's bodies and have adverse effects.

[0003] With the popularization of the environmental protection concept, furniture made of corrugated cardboard has gradually emerged. Existing corrugated cardboard furniture mostly adopts an integrated structure and is difficult to disassemble after installation. However, children grow up quickly, and the existing integrated corrugated cardboard furniture cannot be assembled and spliced independently according to the actual needs of children, making it difficult to meet the needs of children at different stages. Summary of the Invention

The side component board includes an outer panel foldably connected to the middle component board, and the outer panel is foldably connected to an inner panel through an outer folding board that cooperates with the middle component board. Creases are pressed on the entire cut corrugated cardboard. According to different folding areas, the corrugated cardboard is divided into a middle component board, side component boards, upper component boards, and lower component boards. The respective component boards of the corrugated cardboard are folded and combined according to the folding areas, which can reduce and simplify the assembly difficulty and facilitate quick and efficient assembly and splicing into a corrugated cardboard component along the pressed creases and folding areas.

The I-shaped boards 105 are folded between the outer locking holes 116. The plug locking board 104 is inserted into the plug locking hole 117 on the outer panel 115, strengthening the combined rectangular body body to the combined rectangular body feet, so that the corrugated cardboard component forms a stable support structure; the perforated auxiliary board 114 is used when needed and can be disassembled according to the punching position.

[0079] Using multiple combined corrugated cardboard components, assembling and fitting with different-sized connecting components 2 and cooperating with different-sized panel components 6 can assemble into appliances such as beds, tables, and chairs, which is convenient for assembly according to actual needs.

[0080] Example 4 A corrugated cardboard component, different from that in Example 1 in that: a plurality of gap-fitted corrugated reinforcement plates are provided on the inner side surface of the middle structure board; the wave valleys and wave peaks of the corrugated reinforcement plates are connected to and perpendicular to the middle structure board.

[0081] Example 5 A corrugated cardboard component, which is different from that of Embodiment 1 in that: a plurality of waveform reinforcing plates with clearance fit are provided on the inner side surface of the middle structural plate, and the wave valleys and wave peaks of the waveform reinforcing plates are connected to and perpendicular to the middle structural plate; reinforcing holes are provided on the wave peaks of the waveform reinforcing plates, and the reinforcing holes are rotatably connected to the reinforcing rings provided on the inner side surface of the middle structural plate; U-shaped clamping plates with clearance fit with the reinforcing holes are provided on the wave peaks of the waveform reinforcing plates, and both ends of the U-shaped clamping plates are inserted into the clamping holes provided on the inner side surface of the middle structural plate.

[0082] The above are only the preferred embodiments of the present invention, but are not limited to the above examples. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
