Detailed Embodiment

[0021] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are some embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: a reinforced corrugated cardboard box, including: a cardboard box body 1 and a honeycomb panel 2. The honeycomb panel 2 is rectangular and located at the inner end of the cardboard box body 1. A reinforcing member is also placed inside the cardboard box body 1, and the reinforcing member is located between the straight body 1 and the honeycomb panel 2. The honeycomb panel 2 is a honeycomb cardboard in the shape of a mouth, and creases are provided between adjacent sides, facilitating folding of the honeycomb panel 2. After the honeycomb panel 2 is opened and installed inside the cardboard box body 1, it can shield the reinforcing member and protect the objects in the cardboard box body 1. At the same time, the honeycomb panel 2 also has a certain strength to strengthen the cardboard box body 1.

[0023] The reinforcing member includes two rotating shafts 3. Threaded holes 4 are opened at the upper and lower ends of each rotating shaft 3. A connecting bolt 5 is threadedly connected in the threaded hole 4, and the diameter of the nut of the connecting bolt 5 is greater than the diameter of the rotating shaft 3. A rotating frame one 6 and a rotating frame two 7 are respectively rotatably connected to the outer wall of each rotating shaft 3 through a circular ring 8. By unscrewing the connecting bolt 5, the circular ring 8 can be sleeved on the outer wall of the rotating shaft 3 or removed from the outer wall of the rotating shaft 3, which facilitates the disassembly and assembly of the rotating frame one 6 and the rotating frame two 7.

[0024] The upper and lower sides of one end of the rotating frame one 6 and the rotating frame two 7 are fixedly connected to one end outer wall of the circular ring 8 through connecting blocks. The inner wall of the circular ring 8 is slidably sleeved on the outer wall of the rotating shaft 3. The rotating frame one 6 and the rotating frame two 7 can rotate on the outer wall of the rotating shaft 3 through the circular ring 8. Reinforcing rods 9 are fixedly installed at the inner ends of the rotating frame one 6 and the rotating frame two 7. The reinforcing rods 9 are in an X shape to strengthen the rotating frame one 6 and the rotating frame two 7.

[0025] Adjacent rotating frame one 6 and rotating frame two 7 are clamped through a connecting block 11. A connecting groove 10 is opened on the outer side of the end of the rotating frame one 6 far from the rotating shaft 3, and a connecting groove 10 is opened on the inner side of the end of the rotating frame two 7 far from the rotating shaft 3. The connecting groove 10 is in an isosceles trapezoid shape. When the reinforcing member is installed inside the cardboard box body 1, adjacent rotating frame one 6 and rotating frame two 7 will contact, and at the same time, the two connecting grooves 10 communicate. Both ends of the connecting block 11 are in a trapezoid shape, and both ends of the connecting block 11 are respectively slidably inserted into the two connecting grooves 10, thereby fixing adjacent rotating frame one 6 and rotating frame two 7 together. At the same time, the rotating frame one 6 and the rotating frame two 7 are attached to the side inner wall of the cardboard box body 1, playing a role in strengthening the side of the cardboard box body 1. The upper and lower ends of the rotating frame one 6 and the rotating frame two 7 are both connected with top and bottom connecting plates 12.

[0026] The top and bottom connecting plate 12 is in a mouth shape. A limiting hole 13 is opened at one of the diagonals of the top and bottom connecting plate 12. The outer end of the connecting bolt 5 is inserted into the limiting hole 13. At the same time, the side wall of the top and bottom connecting plate 12 is in contact with the upper or lower side wall of the first rotating frame 6 and the second rotating frame 7. The two top and bottom connecting plates 12 are respectively in contact with the inner wall of the upper end or the lower end of the carton body 1. The connecting plate 12 serves to increase the contact area between the reinforcing member and the carton body 1.

[0027] During actual use, first place a top and bottom connecting plate 12 inside the bottom end of the carton body 1. Insert the outer ends of the connecting bolts 5 at the lower ends of the two rotating shafts 3 into the limiting holes 13, and attach the first rotating frame 6 and the second rotating frame 7 to the inner side wall of the carton body 1. Insert the connecting block 11 into two adjacent connecting slots 10. Then, place a top and bottom connecting plate 12 on the upper ends of the two rotating shafts 3. Finally, place the honeycomb spacer 2 inside the reinforcing member, which serves to reinforce the corrugated carton as a whole.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
