[0001] This utility model relates to the field of plastic packaging box technology, and more specifically to a multi-layer combined plastic packaging box. Background Technology

[0002] Plastic packaging boxes refer to containers or boxes made primarily of plastic used for packaging products. These boxes are widely used in the modern packaging industry, featuring diverse designs and strong functionality to meet the packaging needs of different commodities. The raw material for plastic packaging boxes is plastic, a polymer material with excellent processing properties. Plastic is lightweight, high-strength, moisture-proof, waterproof, corrosion-resistant, and easy to process and mold, making plastic packaging boxes perform excellently in protecting goods and facilitating transportation.

[0003] The shortcomings of existing technologies: Traditional plastic packaging boxes are relatively simple in function design, often limited to providing basic packaging and protection. These boxes are generally made of relatively fragile plastic materials, lacking sufficient strength and durability. During use, they are easily subjected to impacts and bumps, leading to cracking, deformation or damage. This damage not only affects the integrity of the materials inside the packaging, but may also cause a series of problems, such as material leakage, pollution and loss. Therefore, it is necessary to design a multi-layered modular plastic packaging box. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-layer combined plastic packaging box to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a multi-layer combined plastic packaging box, including a box body and a lid, wherein the box body and the lid are adapted to each other, a hinge is provided at the rear edge of the top of the box body, the box body is movably connected to the lid through the hinge, two sets of connecting components are symmetrically arranged on the side of the lid away from the hinge, a receiving cavity is opened in the box body, an isolation layer is provided at the bottom of the receiving cavity, a shock-absorbing layer is provided at the bottom of the isolation layer, a limit strip is fixedly connected at the edge of the top of the receiving cavity, and a protective pad is provided on the limit strip.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The multi-layer combined plastic packaging box involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This utility model provides a multi-layer composite plastic packaging box; please refer to [link / reference]. Figure 1-5 As shown, the device includes a box body 1 and a cover body 2. The box body 1 and the cover body 2 are adapted to each other. A hinge 3 is provided at the rear edge of the top of the box body 1. The box body 1 is movably connected to the cover body 2 through the hinge 3. Two sets of connecting components 4 are symmetrically arranged on the side of the cover body 2 away from the hinge 3. A receiving cavity 5 is opened inside the box body 1. An isolation layer 6 is provided at the bottom of the receiving cavity 5. A shock-absorbing layer 7 is provided at the bottom of the isolation layer 6. A limit strip 8 is fixedly connected to the edge of the top of the receiving cavity 5. A protective pad 9 is placed on the limit strip 8. The protective pad 9 protects the material in the receiving cavity 5 from the top, preventing the material from shaking in the receiving cavity 5, which facilitates transportation and packaging management.

[0023] Furthermore, protective plates 10 are fixedly connected to the edges of the outer side walls of the box body 1, and protective sleeves 11 are fixedly connected to the bottom corners of the box body 1. Supporting feet 12 are fixedly connected to the bottom of the protective sleeves 11. By adding protective plates 10 to the edges of the box body 1, the overall strength of the box body 1 is enhanced. The protective sleeves 11 and supporting feet 12 improve the support stability and wear resistance of the packaging box, and further extend its service life.

[0024] Furthermore, protective plates 2 13 are fixedly connected to the edges of the outer walls of the cover 2, and protective sleeves 2 14 are fixedly connected to the corners of the top of the cover 2. The protective sleeves 2 14 have slots 15 that are compatible with the support feet 12. Several fastening plates 16 are fixedly connected to both the protective plates 2 13 and the protective plates 10. The design of the protective plates 2 13 and the protective sleeves 2 14 gives the cover 2 good protective performance. By setting the slots 15 to fix and limit the support feet 12, it is easy to connect the cover 2 of one box 2 to another box 1 when multiple plastic boxes are stacked together during transportation. The fastening plates 16 further enhance the firmness of the connection between the protective plates 2 13 and the protective plates 10 on the cover 2 and the box 1.

[0025] Furthermore, the connecting assembly 4 includes a fixing plate 401, an insert block 402, a connecting plate 403, a slot 404, a connecting shaft 405, a limiting ring 406, and a locking block 407. The fixing plate 401 is fixedly connected to the cover 2, and the insert block 402 is fixedly connected to the bottom of the fixing plate 401. The connecting plate 403 is fixedly connected to the housing 1, and the top of the connecting plate 403 has a slot 404 that is compatible with the insert block 402. The connecting shaft 405 is rotatably connected to the connecting plate 403, and the limiting ring 406 is fixedly connected to the connecting shaft 405. The limiting ring 406 is compatible with the fixing plate 401, and the locking block 407 is fixedly connected to the inner wall of the limiting ring 406, allowing the cover 2 to be opened. The lid 2 is easily opened and closed, and the locking mechanism 407 locks the lid, improving the sealing and security of the packaging box. When the lid 2 is closed, the insert 402 is inserted into the slot 404, and the limiting ring 406 rotates on the connecting plate 403, allowing it to engage with the fixing plate 401. The locking block 407 abuts against the fixing plate 401, achieving a stable connection between the lid 2 and the box body 1, thus maintaining the sealing and security of the packaging box. When it is necessary to open the lid 2, the limiting ring 406 is rotated again to release the connection with the fixing plate 401, thereby releasing the fixation between the lid 2 and the box body 1 and allowing it to be opened smoothly. This makes the plastic packaging box more convenient to use and improves its practicality.

[0026] Furthermore, the isolation layer 6 includes a fiberboard 601 and a fixing block 602. The fixing block 602 is fixedly connected to the bottom corners of the fiberboard 601. The fiberboard 601 has a good isolation effect and can effectively separate the materials in the packaging, prevent the mixing and mutual interference between different materials, and avoid direct contact that may cause wear or contamination. At the same time, the fixing block 602 is fixed by the circular groove 702, so that the fiberboard 601 can be stably fixed in the accommodating cavity 5, which improves its stability in use.

[0027] Furthermore, the shock-absorbing layer 7 includes a foam shock-absorbing plate 701, a circular groove 702, and shock-absorbing holes 703. The top of the foam shock-absorbing plate 701 has a circular groove 702 corresponding to the fixing block 602, and the fixing block 602 is embedded in the circular groove 702. The bottom of the foam shock-absorbing plate 701 has several shock-absorbing holes 703 at equal intervals. The foam shock-absorbing plate 701 has good shock absorption performance and can effectively absorb and buffer the impact of external forces on the packaging box. It can effectively reduce the impact of bumps or vibrations on the items in the accommodating cavity 5 during transportation and protect the safety of the items. At the same time, the cooperation between the circular groove 702 and the fixing block 602 allows the foam shock-absorbing plate 701 to be stably fixed in the accommodating cavity 5, while the shock-absorbing holes 703 can further improve the shock absorption effect and ensure the safety of the items during transportation.

[0028] The working principle of this utility model is as follows: When using this multi-layer combined plastic packaging box, the cover 2 is opened via the hinge 3. First, the materials to be packaged are placed on the isolation layer 6 inside the accommodating cavity 5. The isolation layer 6 can effectively separate different materials, preventing mixing and mutual interference. Then, the protective pad 9 is placed on the limiting strip 8 to protect the materials inside the accommodating cavity 5 from the top. Next, the cover 2 is closed, allowing the insert 402 to be inserted into the slot 404. The limiting ring 406 is rotated to engage with the fixing plate 401, and the cover 2 is locked by the locking block 407. To improve the sealing and safety of the packaging box, the foam shock absorber 701 can effectively absorb and buffer the impact force of the outside world on the packaging box during transportation, reduce the shaking of the items in the accommodating cavity 5, and protect the safety of the items. When multiple plastic packaging boxes are stacked, the slot 15 can fix and limit the support foot 12, so that the cover 2 is tightly connected to another box 1, improving the stacking stability. At the same time, the protective sheet 10, protective sleeve 11, protective sheet 2 13 and protective sleeve 2 14 can enhance the overall strength and wear resistance of the packaging box, and further extend its service life.
