[0002] Corrugated cardboard is the most widely used packaging product, consistently leading the way in terms of usage. This includes calcium-plastic corrugated cardboard. For over half a century, thanks to its superior performance and processing properties, corrugated cardboard has gradually replaced wooden boxes and other transport packaging containers, becoming the mainstay of transport packaging.

[0003] Existing corrugated cardboard boxes are prone to bumps during transportation, which can easily cause damage to the corrugated cardboard boxes. When any side of the corrugated cardboard box is damaged, it will affect the storage environment of the items. In severe cases, it will directly cause the items to leak out, making the entire corrugated cardboard box unusable and having to be discarded, which in turn leads to a waste of resources. Therefore, an environmentally friendly corrugated cardboard box is proposed to solve the above technical problems. Utility Model Content

[0006] Furthermore, a sliding groove for the side paperboard to slide up and down is provided between the opposite sides of two adjacent columns.

[0007] Furthermore, the number of the side paper boards is four, and the upper end surface of the mounting ring is provided with four grooves for inserting the four side paper boards respectively.

[0008] Furthermore, the four baffles are respectively attached to the outer sides of the four side paperboards.

[0009] Furthermore, the cross-section of the upper end of the column is L-shaped, and the bottom paper board is attached to the upper end surface of the carrying ring.

[0010] Furthermore, the length and width of the bottom paperboard are respectively adapted to the length and width of the inner side of the mounting ring, and the lengths and widths of the four side paperboards are equal.

[0011] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0012] When one piece of cardboard in this environmentally friendly corrugated box is damaged, the cover is opened, the damaged cardboard is taken out, and the cardboard to be replaced is placed in the corresponding position, thereby completing the replacement of the damaged side of the cardboard. The cardboard can be replaced and reused, extending the service life of the entire corrugated box, avoiding waste, and being more environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3 , an environmentally friendly corrugated cardboard box in this embodiment includes a carrying ring 1, the inner side of the carrying ring 1 is integrally formed with a cross-shaped bottom plate 2, and a bottom paperboard 10 is placed on the upper surface of the bottom plate 2. During assembly, the bottom paperboard 10 is first placed on the bottom plate 2, and at the same time, the bottom paperboard 10 is located on the inner side of the mounting ring 3, and the mounting ring 3 is fixed to the outer side of the carrying ring 1. The carrying ring 1 and the mounting ring 3 are both rectangular in shape, and columns 4 are fixed to the four corners of the upper end surface of the mounting ring 3. A side paperboard 5 is slidably connected between the opposite sides of two adjacent columns 4, and a baffle 6 is fixed between the opposite sides of two adjacent columns 4. The upper end surfaces of the four columns 4 are attached with the same cover plate 7, and the side paperboard 5, bottom paperboard 10 and cover plate 7 are all made of corrugated cardboard.

[0019] Furthermore, when one of the cardboards is damaged, the cover plate 7 is opened, the damaged cardboard is taken out, and then the cardboard to be replaced is placed in the corresponding position, thereby completing the replacement of the damaged cardboard.
