DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] For example, see Figures 1 to 4 The utility model provides a multi-layer composite corrugated cardboard packaging box, comprising a packaging box body 1, two cover plates 1 4 are symmetrically arranged on the upper surface of the packaging box body 1, two cover plates 2 5 are symmetrically arranged on the upper surface of the packaging box body 1, and plug plates 10 are arranged on the surfaces of the two cover plates 2 5, and slots 6 for inserting and fitting the plug plates 10 are opened on the side of the cover plate 1 4;

[0026] Auxiliary components are arranged in the slot 6 , and fixing components are arranged on the surface of the packaging box body 1 .

[0027] The auxiliary component includes an arc block 13 fixedly connected to the inner wall of the slot 6 , an arc through hole 11 for the arc block 13 to slide into is opened on the surface of the plug board 10 , and a cardboard strip 8 is fixedly connected to the inner wall of the slot 6 .

[0028] There are multiple cardboard strips 8 evenly distributed inside the slot 6 .

[0029] More specifically, when this embodiment is used, Figure 1As shown, the items to be stored are placed into the interior of the packaging box body 1 through the opening on the upper surface of the packaging box body 1, and then the two cover plates 14 are flipped over to a position where they fit the upper surface of the packaging box body 1, and then the cover plate 25 is flipped over to a position where it fits the upper surface of the packaging box body 1, and the two plug plates 10 on its surface are respectively inserted into the slots 6 opened on the side surfaces of the cover plate 14. At this time, under the action of the two plug plates 10, the two cover plates 14 and the two cover plates 25 can be fixed as a whole, thereby completing the sealing operation of the packaging box body 1. Compared with the traditional method of gluing with tape, the sealing is more beautiful, and when the cover plates 14 and the cover plates 25 are opened, the packaging box body 1 will not be damaged, which is conducive to the reuse of cardboard packaging boxes and is worthy of promotion and use.

[0030] It is worth noting that since the arc block 13 is made of corrugated paper and has a certain elastic potential energy, when the plug plate 10 on the surface of the cover plate 2 5 is inserted into the slot 6 opened on the surface of the cover plate 1 4, when the arc through hole 11 on the surface of the plug plate 10 has not yet contacted the arc block 13, the arc block 13 will be squeezed and deformed. As the plug plate 10 continues to be inserted, when the arc through hole 11 contacts the arc block 13, the arc block 13 will be reset and slide into the arc through hole 11 under the action of elastic potential energy, thereby improving the stability of the plug plate 10 after being inserted into the slot 6, so that the seal of the packaging box body 1 will not be easily opened during subsequent transportation, thereby ensuring the protection effect of the items stored in the packaging box body 1.

[0031] The provision of multiple cardboard strips 8 can increase the static friction between the plug board 10 and the slot 6 after the plug board 10 is inserted into the slot 6, further improving the stability of the plug board 10 after the plug board 10 is inserted into the slot 6.

[0032] Embodiment 2, based on the above embodiment:

[0033] Further, the fixing component in the first embodiment is disclosed, the fixing component includes a paper pull ring 7 arranged on the surface of the cover plate 1 4, and a paper hook 3 is fixedly connected to the surface of the packaging box body 1;

[0034] A convex block 9 is fixedly connected to the surface of the packaging box body 1 .

[0035] More specifically, when the present embodiment is used, when it is necessary to open the packaging box body 1 and take out the items stored therein, Figure 1 As shown, similarly, first pull the cover plate 2 5 away from the outside of the cover plate 1 4 to remove the plug plate 10 from the slot 6 on the surface of the cover plate 1 4, and then flip the cover plate 2 5 to a position that fits the front surface of the packaging box body 1, so that the convex block 9 can be inserted into the arc-shaped through hole 11, and the limiting operation of the cover plate 2 5 can be completed at this time.

[0036] The same, such as Figure 2 As shown, cover plate 1 4 is flipped over again so that the paper hook 3 is inserted into the paper pull ring 7, and the position limiting of cover plate 1 4 is completed. At this time, cover plate 1 4 and cover plate 2 5 will not block the opening position on the upper surface of the packaging box body 1, which provides convenience for the user to take out the items in the packaging box body 1.

[0037] It is worth noting that the paper pull ring 7 on the surface of the cover plate 4 can facilitate the movement of the packaging box body 1 after sealing, and the paper hook 3 can be used to hang small items such as packaging bags, further increasing the number of items that can be stored in the packaging box body 1, making it more practical.

[0038] Embodiment 3, based on the above embodiment:

[0039] Furthermore, in order to enable the packaging box body 1 to be used in a variety of usage environments, the packaging box body 1 includes a corrugated inner layer 103, a heat-insulating cotton layer 102 and an outer reinforcement layer 101, and the outer reinforcement layer 101 is made of multiple layers of kraft paper bonded together.

[0040] The lower surface of the packaging box body 1 is fixedly connected with a hollow plate 2, and the surface of the hollow plate 2 is evenly provided with a plurality of hollow grooves 12. The hollow plate 2 is made of multiple layers of corrugated paper bonded together.

[0041] The provision of the thermal insulation surface layer 102 enables the packaging box body 1 to be adapted to the storage and transportation of some items that require insulation, and the outer reinforcement layer 101 made by gluing multiple layers of kraft paper can improve the wear resistance and pressure resistance of the packaging box body 1. The provision of the hollow plate 2 on the lower surface of the packaging box body 1 can prevent the packaging box body 1 from directly contacting the corrosive substances on the ground, thereby improving the service life of the packaging box body 1.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
