Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically to a splicing type environmentally friendly corrugated cardboard box. Background Technology

[0002] Currently, most mainstream corrugated cardboard boxes rely on plastic tape or chemical adhesives for assembly and sealing. Plastic tape, being non-biodegradable, creates mixed pollution after the boxes are discarded, significantly increasing recycling and sorting costs. Furthermore, residual tape damages the pulp fiber structure, causing a decrease in the strength of recycled paper by more than 20%. Chemical adhesives, on the other hand, contain volatile organic compounds that continuously release harmful substances during storage and transportation, posing potential safety risks to packaged food products.

[0003] Traditional cardboard boxes use a one-piece glued structure, with side panels, bottom panels, and lid glued together as a non-removable unit. When a part of the box, such as a single side panel, is damaged due to impact or moisture, the damaged panel cannot be replaced independently and the entire box must be discarded. Statistics show that this structural waste results in approximately 30% of paper materials being discarded due to partial damage, causing significant resource waste. Utility Model Content

The inner side of the first L-shaped connector 4 is in contact with the side plate 5 and the bottom plate 6. The second L-shaped connector 9 is provided on the top corner of the triangular connector 1. The concave corner of the second L-shaped connector 9 is used to accommodate the boundary edge of two adjacent side plates 5. The inner side of the second L-shaped connector 9 is in contact with the side plate 5.

[0028] The inner side of the first L-shaped connector 4 is provided with a first L-shaped connecting groove 10. The outer end of the first L-shaped connecting groove 10 is open. Each side of the bottom edge of the same side plate 5 is supported by a first L-shaped connector 4. The two adjacent first L-shaped connectors 4 are connected by a first convex connecting plate 11. The two ends of the first convex connecting plate 11 are respectively inserted into the first L-shaped connecting grooves 10 on both sides. The first convex connecting plate 11 and the first L-shaped connecting groove 10 are slidably engaged, so that the first convex connecting plate 11 and the first L-shaped connector 4 are telescopic and their lengths are adjustable, thereby flexibly adapting to the length of the side plate 5. The inner wall of the first convex connecting plate 11 can fit against the side plate 5 and the bottom plate 6, thereby ensuring the contact area and providing sufficient support. The side and bottom center of the first convex connecting plate 11 are provided with second connecting holes 13.

[0029] The junction of two adjacent side plates 5 is covered by a second L-shaped connector 9; a second L-shaped connecting groove 12 is provided on the inner side of the second L-shaped connector 9, the upper end of the second L-shaped connecting groove 12 is open, and a second convex connecting plate 14 is slidably fitted inside the second L-shaped connecting groove 12, so that the second L-shaped connector 9 and the second convex connecting plate 14 are telescopic and height adjustable, thereby flexibly adapting to the height of the side plate 5; the inner wall of the second convex connecting plate 14 fits against the side plate 5 to provide sufficient protection; a right-angle connector 15 is provided at the top of the second convex connecting plate 14, and the two inner sides of the right-angle connector 15 fit against the side plate 5; a third connecting hole 16 is provided on the right-angle connector 15.
