[0017] By adopting the above technical solution, the first sliding groove, the first sliding block, the second sliding groove, and the second sliding block can be used to disassemble and assemble the corresponding first protective plate and the second protective plate. The first protective plate and the second protective plate can be used to arrange the items placed in the box in layers, and can also further protect the items.
[0018] Preferably, the lengths of the first sliding groove and the second sliding groove are both greater than the lengths of the corresponding first sliding block and the second sliding block.
[0019] By adopting the above technical solution, the lengths of both the first sliding groove and the second sliding groove are greater than the lengths of the corresponding first sliding block and the second sliding block, thereby enabling sliding adjustment.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. This application utilizes a box body and other components to form a box body by bonding multiple cardboard pieces together. A first guide plate and a second guide plate are then bonded to the box body. The first and second hinged panels can be installed using corresponding first and second fixing plates. This allows the first and second hinged panels on both sides to slide on the corresponding first and second fixing plates. Furthermore, by bonding the first and second handles, the first and second hinged panels can be easily opened, achieving a hinged opening design without the need for an additional opening and closing mechanism. Therefore, this further improves the subsequent environmental protection effect.

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0030] This application discloses a hinged packaging box.
[0031] Reference Figure 1-3 A hinged packaging box includes a box body 1 composed of multiple cardboard pieces glued together, the box body 1 having a hinged opening mechanism and a protective mechanism disposed inside the box body 1;
[0032] The hinge mechanism includes a first guide plate 2 and a second guide plate 3 bonded to the top of the box body 1. A first fixing plate 10 and a second fixing plate 11 are bonded to the sides of the first guide plate 2 and the second guide plate 3 that are close to each other. A first hinge plate 4 and a second hinge plate 5 are slidably installed on the first fixing plate 10 and the second fixing plate 11 respectively. The interface splicing of the first hinge plate 4 and the second hinge plate 5 is correspondingly adapted. A first handle 6 and a second handle 14 are bonded to the sides of the first hinge plate 4 and the second hinge plate 5 that are far from each other. The first hinge plate 4 and the second hinge plate 5 are both two-layered, and the same corresponding connecting rod 13 is bonded to the sides that are close to each other.
[0033] Among them, the four sides of the box body 1 are all glued with corresponding reinforcing side sleeves 7, the bottom of the box body 1 is provided with a reinforcing base plate 8, and the two sides of the reinforcing base plate 8 are glued with corresponding connecting plates 9. Both connecting plates 9 are glued to the box body 1.
[0034] In use, multiple cardboard pieces are glued together to form a box body 1, and the first guide plate 2 and the second guide plate 3 are glued to the box body 1. At this time, the first hinged plate 4 and the second hinged plate 5 can be installed through the corresponding first fixing plate 10 and the second fixing plate 11, so that the first hinged plate 4 and the second hinged plate 5 on both sides can be slidably installed on the corresponding first fixing plate 10 and the second fixing plate 11. Then, by gluing the first handle 6 and the second handle 14, it is easy to open the corresponding first hinged plate 4 and the second hinged plate 5, and a hinged opening setting can be realized without the need to set up an additional opening and closing mechanism, thus further improving the subsequent environmental protection effect.
[0035] Reference Figure 4-5 The protective mechanism includes a partition 12 bonded to the box body 1. The partition 12 has a first sliding groove 15 and a second sliding groove 18 on its two sides respectively. The first sliding groove 15 and the second sliding groove 18 are staggered. The first sliding block 16 and the second sliding block 19 are slidably installed in the first sliding groove 15 and the second sliding groove 18. The first protective plate 17 and the second protective plate 20 are fixedly installed on the side of the first sliding block 16 and the second sliding block 19 that are far away from each other. The length of the first sliding groove 15 and the second sliding groove 18 is greater than the length of the corresponding first sliding block 16 and the second sliding block 19.
[0036] In use, the first sliding groove 15, the first sliding block 16, the second sliding groove 18, and the second sliding block 19 can be used to disassemble and assemble the corresponding first protective plate 17 and the second protective plate 20. The first protective plate 17 and the second protective plate 20 can be used to arrange the items placed in the box 1 in layers, and can also further protect the items.
[0037] The implementation principle of a hinged packaging box according to an embodiment of this application is as follows: In use, multiple cardboard pieces are glued together to form a box body 1, and a first guide plate 2 and a second guide plate 3 are glued onto the box body 1. At this time, the first hinged plate 4 and the second hinged plate 5 can be installed through the corresponding first fixing plate 10 and the second fixing plate 11, so that the first hinged plate 4 and the second hinged plate 5 on both sides can be slidably installed on the corresponding first fixing plate 10 and the second fixing plate 11. Then, by gluing the first handle 6 and the second handle 14, it is easy to open the corresponding first hinged plate 4 and the second hinged plate 5, and a hinged setting can be realized without the need to set an additional opening and closing mechanism, thus further improving the subsequent environmental protection effect.
[0038] The first sliding groove 15, the first sliding block 16, the second sliding groove 18, and the second sliding block 19 allow for the assembly and disassembly of the corresponding first protective plate 17 and second protective plate 20. The first protective plate 17 and the second protective plate 20 allow for the layering of items placed inside the box 1, and further provide protection for the items.
[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
