Description

Technical Field

[0001] This utility model relates to the field of packaging engineering technology, and in particular to a double-section printed packaging box. Background Technology

[0002] The double-unit printed packaging box utilizes integrated molding and printing adaptation and usage scenario optimization to achieve high efficiency and practicality in packaging two items together. The pre-crease design is achieved through the cardboard creasing process, and the box body is automatically formed by the fold line when folding. The symmetry of the double-unit structure ensures that the two sides of the box open or close simultaneously, improving assembly efficiency.

[0003] Traditional double-panel printed packaging boxes use a die-cutting process to unfold the two box bodies into a single plane. Figure 1 Integrated cutting, sharing a single side and connecting strip, reduces the splicing process of independent boxes. The connecting parts adopt a single crease line design, relying on the cardboard's own toughness to achieve folding connection. The structural strength is overly dependent on the material thickness.

[0004] Existing double-unit printed packaging boxes, through the design of the connecting parts, folding creases, and flexible connecting materials, allow one packaging box to be folded simultaneously via the connecting point, avoiding the cumbersome operation of individual boxes. Multiple independent packaging boxes can be linked together through a special structural design. However, the problem of the internal dimensions of the individual packaging boxes not being able to fit the actual size of the product still exists. Therefore, a double-unit printed packaging box is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a double-unit printed packaging box to improve the problem that the internal structure of the existing independent packaging box cannot be adapted to the actual size of the product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a double-unit printed packaging box, including a main box, two storage boxes fixedly connected to the inner wall of the main box, a fixing mechanism being provided inside the storage boxes, a sealing cover being fixedly connected to the rear side of the outer wall of the main box, and a disassembly mechanism being provided outside the sealing cover. The fixing mechanism includes multiple bases, the bottoms of which are fixedly connected to the inner wall of the storage box, the tops of which are fixedly connected to limit plates, the tops of which are fixedly connected to fixing rods, the outer walls of which are slidably connected to sliding blocks, the tops of which are fixedly connected to connecting plates, the inner walls of which are both storage boxes have embedded grooves, and the outer surfaces of which are connected plates are provided with limiting components.

[0007] As a further description of the above technical solution: The disassembly mechanism includes multiple leaf plates. The front side of the outer wall of each leaf plate is fixedly connected to the rear side of the outer wall of the sealing cover. The bottom of each leaf plate is fixedly connected to an outer plate. The inner wall of each outer plate is fixedly connected to a fixing button. The inner wall of each outer plate is fixedly connected to a barrier plate. The inner wall of each barrier plate is fixedly connected to a connecting rod. The outer wall of each leaf plate is provided with a threaded groove. The connecting rod is provided with a positioning component on its exterior.

[0008] As a further description of the above technical solution: The limiting component includes multiple movable plates, the bottoms of which are fixedly connected to the top of the connecting plate, anti-collision pads fixedly connected to the outer walls of the multiple movable plates, second fixing magnets fixedly connected to the outer walls of the multiple movable plates, and first fixing magnets fixedly connected to the inner walls of the two storage boxes.

[0009] As a further description of the above technical solution: The positioning component includes multiple internal gears, the inner walls of which are fixedly connected to the outer wall of the connecting rod, and the outer walls of which are meshed with external gears.

[0010] As a further description of the above technical solution: The outer walls of both storage boxes are fixedly connected with partition plates, and the inner walls of the multiple threaded grooves are threaded with bolts.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the fixing mechanism is supported by multiple bases. The sliding block is sleeved on the outer wall of the fixing rod to realize the sliding function. The connecting plate is connected to the top of the sliding block to realize the product fixing of the moving plate. The anti-collision pad on the outer wall can prevent the product from being damaged by collision.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 4An embodiment of this utility model is provided: a double-link printed packaging box, including a main box 1, with two storage boxes 4 fixedly connected to the inner wall of the main box 1. The main function of the storage boxes 4 is to store things. A fixing mechanism 3 is provided inside the storage boxes 4. A sealing cover 2 is fixedly connected to the rear side of the outer wall of the main box 1. A disassembly mechanism 6 is provided outside the sealing cover 2. The fixing mechanism 3 includes multiple bases 301, whose main function is to support the entire fixing mechanism 3. The bottoms of the multiple bases 301 are fixedly connected to the inner wall of the storage box 4. The tops of the multiple bases 301 are fixedly connected to limit plates 302, whose main function is to limit the excessive movement of sliding blocks 304 and prevent damage to components. The tops of the multiple bases 301 are fixedly connected to fixing rods 303, which are fixedly connected to moving plates 3073. The outer walls of the multiple fixing rods 303 are slidably connected to sliding blocks 304, whose main function is to slide. The tops of the multiple sliding blocks 304 are fixedly connected to connecting plates 305. The inner walls of both storage boxes 4 are provided with embedding grooves 306. A limiting component 307 is provided on the outside of the connecting plate 305. The limiting component 307 includes multiple movable plates 3073, the main function of which is to fix the product. The bottom of the multiple movable plates 3073 is fixedly connected to the top of the connecting plate 305. Anti-collision pads 3072 are fixedly connected to the outer walls of the multiple movable plates 3073, the main function of which is to prevent the movable plates 3073 from being damaged by excessive collision. Second fixing magnets 3074 are fixedly connected to the outer walls of the multiple movable plates 3073. First fixing magnets 3071 are fixedly connected to the inner walls of the two storage boxes 4. The products of different sizes are fixed by using the principle of like poles repulsion of magnetic blocks in conjunction with the second fixing magnets 3074. Specifically, the fixing mechanism 3 includes multiple bases 301, which support the entire fixing mechanism 3 and prevent the mechanism itself from becoming loose. Limiting plates 302 on the top of the multiple bases 301 prevent the sliding block 304 from disengaging from the fixing rod 303, ensuring that the sliding block 304's movement range is within the effective working range. Simultaneously, the fixing rod 303 on the top of the multiple bases 301 prevents the sliding block 304 from shifting or shaking, providing accurate guidance for the movement of subsequent components. Connecting plates 305 on the top of the multiple sliding blocks 304 allow for overall adjustment of the position of the limiting component 307. The first fixing magnet 3071 is fixed via the embedded grooves 306 on the inner walls of the two storage boxes 4. It includes multiple movable plates 3073, which serve as limiting components that directly contact the item. Their positions are adjusted as the connecting plate 305 and the sliding block 304 move. Through the cooperation of the multiple movable plates 3073, the item is surrounded and clamped from different directions to prevent lateral swaying. At the same time, the anti-collision pads 3072 on the outer walls of the multiple movable plates 3073 cushion the impact force when the movable plates 3073 collide slightly due to swaying, avoiding direct rigid contact between the movable plates 3073 and the item, which would cause wear and damage to the item's surface. It also reduces collision noise. The second fixed magnet 3074 and the first fixed magnet 3071 can fix the movable plates 3073 to products of different sizes by utilizing the principle of like poles repulsion.

[0020] Reference Figure 1 , Figure 3 and Figure 5 The disassembly mechanism 6 includes multiple leaf plates 601, which mainly drive the entire disassembly mechanism 6 to move synchronously. The front side of the outer wall of each leaf plate 601 is fixedly connected to the rear side of the outer wall of the sealing cover 2. The bottom of each leaf plate 601 is fixedly connected to an outer plate 602, which mainly functions to cooperate with the movement of the leaf plates 601. The inner wall of each outer plate 602 is fixedly connected to a fixing button 603, which mainly functions to prevent the internal structure from falling off. The inner wall of each outer plate 602 is fixedly connected to a barrier plate 604, which mainly functions to separate the internal space of the outer plate 602 and prevent the components from interfering with each other. To prevent interference, connecting rods 605 are fixedly connected to the inner walls of multiple barrier plates 604. Their main function is to fix and connect various parts. Threaded grooves 607 are opened on the outer walls of multiple leaf plates 601. Positioning components 606 are provided on the outside of multiple connecting rods 605. Positioning components 606 include multiple internal gears 6062. The inner walls of multiple internal gears 6062 are fixedly connected to the outer walls of connecting rods 605. External gears 6061 are meshed with the outer walls of multiple internal gears 6062. When the gears rotate, they drive the leaf plates 601 to adjust their angle. Specifically, the disassembly mechanism 6 includes multiple leaf plates 601, which serve as the main frame of the disassembly mechanism 6. The front of each leaf plate 601 is fixedly connected to the rear of the sealing cover 2, integrating the entire disassembly mechanism 6 and the sealing cover 2 into one unit. This ensures that the disassembly mechanism 6 moves synchronously with the sealing cover 2. The leaf plates 601 are moved by the outer plates 602 at their bottom, which also enhances the structural strength of the leaf plates 601. Fixing buttons 603 on the inner walls of the outer plates 602 prevent accidental separation of the mechanism's internal components when not in a disassembled state. Additionally, the inner walls of the outer plates 602 are equipped with barrier plates 6... 04. By limiting the movement range of other moving parts through its own structure, it prevents excessive movement that could lead to connection failure. The connecting rods 605 on the inner walls of multiple baffles 604 achieve accurate positioning and connection, avoiding component offset and shaking. At the same time, the threaded grooves 607 on the outer walls of multiple leaf plates 601 further enhance the connection strength between the sealing cover 2 and the leaf plates 601. The threaded fastening provides a more stable connection force. The outer gears 6061 on the outer walls of multiple internal gears 6062 cooperate with the internal gears 6062 to drive the leaf plates 601 to adjust their angle when the gears rotate.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The outer walls of both storage boxes 4 are fixedly connected with partition plates 5, which mainly prevent the two storage boxes 4 from shaking and colliding. The inner walls of multiple threaded grooves 607 are threaded with bolts 7, which mainly allow for disassembly. The front side of the outer wall of the sealing cover 2 is fixedly connected with two magnetic blocks 8, and the front side of the outer wall of the main box 1 is fixedly connected with two magnetic blocks 9. The magnetic blocks 8 work together to close the sealing cover 2 and the main box 1. The bottom of the main box 1 is fixedly connected with a bottom plate 10, which mainly enhances the load-bearing capacity of the bottom of the main box 1. The inner walls of both storage boxes 4 are provided with storage slots 11, which mainly allow for precise positioning of objects. The inner walls of both storage boxes 4 are provided with fixing slots 12, which allow for shaking-free fixing. The outer walls of the two magnetic blocks 8 are fixedly connected to the outer walls of the magnetic blocks 9. Specifically, the partition plates 5 on the outer walls of the two storage boxes 4 prevent the storage boxes 4 from squeezing and colliding with each other inside the main box 1. At the same time, independent storage areas are divided according to the type of items for easy classification and storage. Multiple threaded grooves 607 are used to connect the threaded bolts 7 for detachable operation. The sealing cover 2 and the main box 1 are closed by magnetic block 2 9 and cooperating magnetic block 1 8. The bottom plate 10 of the main box 1 can effectively enhance the bottom load-bearing capacity of the main box 1. Meanwhile, the storage slots 11 on the inner walls of the two storage boxes 4 are mainly for precise positioning of objects to prevent items from rolling around inside the storage boxes 4. The fixing slots 12 on the inner walls of the two storage boxes 4 are used to position the fixing mechanism 3 to prevent the fixing mechanism 3 from leaving the working area.

[0022] Working principle: First, the fixing mechanism 3 supports the entire mechanism through multiple bases 301. The sliding block 304 is sleeved on the outer wall of the fixing rod 303 to realize the sliding function. The connecting plate 305 is connected to the top of the sliding block 304 to realize the moving plate 3073 to fix the product. The anti-collision pad 3072 on its outer wall can prevent the product from being damaged by collision. The second fixing magnet 3074 on the moving plate 3073 cooperates with the first fixing magnet 3071 on the inner wall of the storage box 4. Using the principle of like poles repulsion of magnetic blocks, the product of different sizes can be fixed, which improves the protection and stability of the product. Furthermore, the mechanism is integrated with the sealing cover 2 by disassembling and connecting multiple leaf plates 601, allowing them to move synchronously. When the sealing cover 2 needs to be removed, only the bolts 7 on a portion of the leaf plates 601 need to be removed. The threaded grooves 607 on the outer wall of the leaf plates 601 enhance the connection strength between the sealing cover 2 and the leaf plates 601 and facilitate disassembly by operators, reducing the difficulty of disassembly.
