Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a double-hook bottom structure for packaging boxes. Background Technology

[0002] Packaging boxes (also known as shipping cartons) are rigid or semi-rigid containers used to contain, protect, transport, store, and display goods. They are typically made of materials such as paper, plastic, metal, and wood, and are widely used in industrial production, commodity distribution, logistics, and daily life. Their core function is to achieve physical protection of the contents and improve circulation efficiency through structural design and material properties.

[0003] Existing packaging boxes often use nailing, gluing, or simple snap-fit ​​structures to connect the bottom and side panels. This design is not only inefficient, but nails are also prone to loosening, leading to structural collapse. Gluing is affected by ambient temperature and humidity, and the adhesive is prone to failure with long-term use. In addition, residual adhesive can contaminate materials and is not conducive to recycling. Traditional snap-fit ​​and slot designs are mostly single fixed positions, which cannot be adjusted according to the weight and volume requirements of the actual items loaded in the packaging box. When loading irregularly shaped items, the fixed snap-fit ​​cannot adapt to the adjustment requirements of the side panels, further reducing the strength of the side panel connection and affecting the overall load-bearing stability. In addition, the existing internal space of the boxes is mostly a one-piece design, lacking flexible partition structures. When packaging items of multiple sizes at the same time, items are prone to collision and compression, reducing the packaging protection effect. In view of this, we propose a double-hook bottom structure for packaging boxes. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a double-hook bottom structure for packaging boxes. This solves the problem that existing packaging boxes often use nailing, gluing, or simple snap-fit ​​structures to connect the bottom and side panels. These designs are not only inefficient, but nails are also prone to loosening, leading to structural collapse. Gluing methods are affected by ambient temperature and humidity, and adhesives are prone to failure over time, leaving residues that contaminate materials and hinder recycling. Traditional snap-fit ​​and slot designs are mostly single-fixed, unable to adjust their positions according to the weight and volume of the items loaded. When loading irregularly sized items, the fixed snap-fit ​​cannot accommodate the adjustment needs of the side panels, further reducing the strength of the side panel connection and affecting overall load-bearing stability. Furthermore, existing boxes often have a single-piece internal space design, lacking flexible partitioning. When packaging items of various sizes simultaneously, collisions and compression can easily occur, reducing the effectiveness of packaging protection.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A double-hook bottom structure for packaging boxes includes:

[0009] A first main plate, a second main plate is provided on one side of the first main plate, a first bottom plate is rotatably installed on the bottom of the first main plate, a second bottom plate is rotatably installed on the bottom of the second main plate, the top surface of the first bottom plate is in contact with the bottom surface of the second bottom plate, a first side plate is rotatably installed on both sides of the first main plate, a second side plate is rotatably installed on both sides of the second main plate, and the two first side plates are in contact with the two second side plates respectively.

[0010] The mounting components are respectively disposed on the first base plate, the second base plate, the two first side plates and the two second side plates, and are used for quickly assembling the packaging box.

[0011] Preferably, the mounting assembly includes multiple semi-circular limiting blocks, wherein three of the semi-circular limiting blocks are fixedly installed on the bottom surface of the second base plate, and three semi-circular limiting blocks are fixedly installed on the top surface of the two second side plates. Nine semi-circular limiting grooves are opened on the top surface of the first base plate and one side of the two first side plates. The nine semi-circular limiting grooves are evenly distributed, and the multiple semi-circular limiting blocks are respectively engaged with the corresponding semi-circular limiting grooves.

[0012] Preferably, a cover plate is rotatably mounted on the top of the first main body plate, and a storage groove is provided on the top of the second main body plate, wherein the storage groove is sleeved with the cover plate.

[0013] Preferably, the inner sidewalls of the first main plate and the second main plate are symmetrically provided with multiple sliding grooves, and the same partition is movably connected between the two corresponding sliding grooves.

[0014] Preferably, handles are fixedly installed on the outer side walls of both the first main body plate and the second main body plate.

[0015] Preferably, the first main body plate, the second main body plate, the first bottom plate, the second bottom plate, the two first side plates, the two second side plates, and the cover plate are all made of five layers of high-strength corrugated cardboard.

[0016] Preferably, the outer side walls of both the first main body plate and the second main body plate are provided with anti-slip texture.

[0017] (III) Beneficial Effects

[0018] 1. In the initial assembly stage, the first and second main body plates serve as the side support frames of the packaging box. They unfold from a folded state to an upright state by rotation. Once the two main body plates are upright, the first and second bottom plates connected to them are simultaneously flipped downwards until the top surface of the first bottom plate is in complete contact with the bottom surface of the second bottom plate, forming a double-layered bottom support structure for the packaging box. Simultaneously, the first side plates on both sides of the first main body plate and the second side plates on both sides of the second main body plate also flip outwards to a horizontal state, with the edges of the first and second side plates contacting each other, jointly providing lateral protection for the packaging box. This completes the initial assembly of the overall frame. During this process, the connection design between the first and second main body plates, the first bottom plate, the second bottom plate, the first side plates, and the second side plates ensures the unfolding of each component. The synchronicity and smoothness of the opening lay the foundation for subsequent fixing steps. After the first base plate and the second base plate are attached, the three semi-circular limiting blocks pre-set on the bottom surface of the second base plate enter the corresponding semi-circular limiting grooves on the top surface of the first base plate. Utilizing the characteristics of the arc structure, the horizontal displacement of the base plate is restricted, preventing misalignment at the bottom. At the same time, the semi-circular limiting blocks on the top surfaces of the two second side plates also respectively engage with the semi-circular limiting grooves on one side of the corresponding first side plate. Since the semi-circular limiting grooves are evenly distributed, the engagement position can be adjusted according to the actual loading requirements of the packaging box, further enhancing the firmness of the side plate connection. This fastener-free engagement method, with the help of the concave and convex structure of the semi-circular limiting blocks and semi-circular limiting grooves, achieves rapid positioning and fixing, while avoiding the damage to materials caused by traditional nailing and gluing, improving assembly efficiency and structural reusability.

[0019] 2. After the main frame assembly is completed, the cover plate on the top of the first main plate can be flipped up and cover the top of the second main plate. The cover plate and the storage slot on the top of the second main plate fit together. The tight fit between the storage slot and the cover plate achieves a seal on the top of the packaging box, preventing dust and debris from entering the box. If it is necessary to divide the internal space of the box, the partition can be inserted along the slide. The position of the partition can be flexibly adjusted according to the size of the items to achieve classified storage of multiple items. In addition, the handle design on the outer side wall of the first and second main plates provides the operator with a point of leverage, reducing the difficulty of handling. The first main plate, second main plate, first bottom plate, second bottom plate, first side plate, second side plate and cover plate are made of five layers of high-strength corrugated cardboard, which greatly improves the overall load-bearing capacity and impact resistance. The anti-slip texture on the outer side wall of the first and second main plates increases friction and prevents the packaging box from slipping out of the hand during handling.

[0029] A first main plate 1, a second main plate 2 is disposed on one side of the first main plate 1, a first base plate 3 is rotatably mounted on the bottom of the first main plate 1, a second base plate 4 is rotatably mounted on the bottom of the second main plate 2, the top surface of the first base plate 3 is in contact with the bottom surface of the second base plate 4, first side plates 5 are rotatably mounted on both sides of the first main plate 1, and second side plates 6 are rotatably mounted on both sides of the second main plate 2, with each of the two first side plates 5 in contact with the two second side plates 6 respectively; mounting components are respectively disposed on the first base plate 3, the second base plate 4, the two first side plates 5, and the two second side plates 6, and... For rapid assembly of packaging boxes, in the initial assembly stage, the first main body plate 1 and the second main body plate 2 serve as the two side support frames of the packaging box. They are rotatably connected to unfold from a folded state to an upright state. Once the two main body plates are upright, the first bottom plate 3 and the second bottom plate 4, which are rotatably connected to them, simultaneously flip downwards until the top surface of the first bottom plate 3 and the bottom surface of the second bottom plate 4 are completely flush, forming a double-layered bottom support structure for the packaging box. At the same time, the first side plates 5 on both sides of the first main body plate 1 and the second side plates 6 on both sides of the second main body plate 2 also flip outwards to a horizontal state. The edges of plate 5 and the second side plate 6 contact each other, forming the side enclosure of the packaging box and completing the initial splicing of the overall frame. During this process, the rotational connection design between the first main plate 1, the second main plate 2, the first bottom plate 3, the second bottom plate 4, the first side plate 5, and the second side plate 6 ensures the synchronicity and smoothness of the unfolding of each component, laying the foundation for the subsequent fixing steps. When the first bottom plate 3 and the second bottom plate 4 are attached, the three semi-circular limiting blocks 8 pre-set on the bottom surface of the second bottom plate 4 are precisely embedded in the corresponding semi-circular limiting grooves 7 on the top surface of the first bottom plate 3. Utilizing the fitting characteristics of the arc structure, the limiting blocks are... The horizontal displacement of the base plate prevents misalignment at the bottom. At the same time, the semi-circular limiting blocks 8 on the top surface of the two second side plates 6 are respectively engaged in the semi-circular limiting grooves 7 on the corresponding side of the first side plate 5. Since the semi-circular limiting grooves 7 are evenly distributed, the buckle position can be adjusted according to the actual loading requirements of the packaging box, further enhancing the firmness of the side plate connection. This fastener-free buckling method achieves rapid positioning and fixing by means of the mechanical interlocking principle of the concave and convex structure of the semi-circular limiting blocks 8 and the semi-circular limiting grooves 7, while avoiding the damage to materials caused by traditional nailing and bonding, and improving assembly efficiency and structural reusability.

[0032] The installation assembly includes multiple semi-circular limiting blocks 8, three of which are fixedly installed on the bottom surface of the second base plate 4, and three semi-circular limiting blocks 8 are fixedly installed on the top surfaces of the two second side plates 6. Nine semi-circular limiting grooves 7 are provided on the top surface of the first base plate 3 and on one side of the two first side plates 5. These nine semi-circular limiting grooves 7 are evenly distributed. The multiple semi-circular limiting blocks 8 are respectively engaged with the corresponding semi-circular limiting grooves (7). When the first base plate 3 and the second base plate 4 are attached, the three semi-circular limiting blocks 8 pre-set on the bottom surface of the second base plate 4 are precisely embedded into the corresponding semi-circular limiting grooves 7 on the top surface of the first base plate 3, thus utilizing… The curved structure's fitting characteristics limit the horizontal displacement of the base plate, preventing misalignment at the bottom. Simultaneously, the semi-circular limiting blocks 8 on the top surfaces of the two second side plates 6 are respectively engaged in the semi-circular limiting grooves 7 on the corresponding side of the first side plate 5. Since the semi-circular limiting grooves 7 are evenly distributed, the buckle position can be adjusted according to the actual loading requirements of the packaging box, further enhancing the firmness of the side plate connection. This fastener-free buckling method, relying on the mechanical interlocking principle of the concave and convex structure of the semi-circular limiting blocks 8 and the semi-circular limiting grooves 7, achieves rapid positioning and fixation, while avoiding the damage to materials caused by traditional nailing and bonding, improving assembly efficiency and structural reusability.

The cover plate 9 is fitted with the storage groove 10 on the top of the second main body plate 2. The tight fit between the storage groove 10 and the cover plate 9 achieves the sealing of the top of the packaging box, preventing dust and debris from entering the box.

If it is necessary to divide the space inside the box, the partition can be inserted along the sliding grooves 11 symmetrically provided on the inner walls of the first main plate 1 and the second main plate 2. By using the guiding and limiting function of the sliding grooves 11 on the partition, the position of the partition can be flexibly adjusted according to the size of the items, so as to realize the classification and storage of multiple items.

[0041] Handles 12 are fixedly installed on the outer walls of the first main plate 1 and the second main plate 2.

[0043] This embodiment provides a double-hook bottom structure for packaging boxes, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] Among them, the first main board 1, the second main board 2, the first bottom board 3, the second bottom board 4, the two first side boards 5, the two second side boards 6 and the cover board 9 are all made of five-layer high-strength corrugated cardboard. The first main board 1, the second main board 2, the first bottom board 3, the second bottom board 4, the first side boards 5, the second side boards 6 and the cover board 9, made of five-layer high-strength corrugated cardboard, improve the overall load-bearing capacity and impact resistance through the buffer and support structure of the multi-layer corrugated cardboard.

[0045] Example 7:

[0046] This embodiment provides a double-hook bottom structure for packaging boxes, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] The outer walls of both the first main body plate 1 and the second main body plate 2 are provided with anti-slip textures. The anti-slip textures on the outer walls of the first main body plate 1 and the second main body plate 2 increase friction and prevent the packaging box from slipping out of your hands during handling.

[0048] Working Principle: In the initial assembly stage, the first main body plate 1 and the second main body plate 2 serve as the two side support frames of the packaging box. They are rotated together to unfold from a folded state to an upright state. Once the two main body plates are upright, the first bottom plate 3 and the second bottom plate 4, which are rotated together with them, simultaneously flip downwards until the top surface of the first bottom plate 3 and the bottom surface of the second bottom plate 4 are completely flush, forming a double-layered bottom support structure for the packaging box. At the same time, the first side plates 5 on both sides of the first main body plate 1 and the second side plates 6 on both sides of the second main body plate 2 also flip outwards to a horizontal state, with the edges of the first side plates 5 and the second side plates 6 contacting each other, forming the side enclosures of the packaging box and completing the initial splicing of the overall frame. During this process, the rotational connection design between the first main body plate 1, the second main body plate 2, the first bottom plate 3, the second bottom plate 4, the first side plates 5, and the second side plates 6 ensures the unfolding of each component. The synchronicity and smoothness of the timing lay the foundation for subsequent fixing steps. After the first base plate 3 and the second base plate 4 are attached, the three semi-circular limiting blocks 8 pre-set on the bottom surface of the second base plate 4 are precisely embedded in the corresponding semi-circular limiting grooves 7 on the top surface of the first base plate 3. Utilizing the fitting characteristics of the arc structure, the horizontal displacement of the base plate is restricted to prevent misalignment at the bottom. At the same time, the semi-circular limiting blocks 8 on the top surface of the two second side plates 6 are also respectively snapped into the semi-circular limiting grooves 7 on the corresponding side of the first side plate 5. Since the semi-circular limiting grooves 7 are evenly distributed, the buckle position can be adjusted according to the actual loading requirements of the packaging box, further enhancing the firmness of the side plate connection. This fastener-free buckling method, with the mechanical interlocking principle of the concave and convex structure of the semi-circular limiting blocks 8 and the semi-circular limiting grooves 7, achieves rapid positioning and fixing, while avoiding the damage to materials caused by traditional nailing and bonding, improving assembly efficiency and structural reusability.

[0049] After the main frame assembly is completed, the cover plate 9 on the top of the first main body plate 1 can be flipped upwards to cover the top of the second main body plate 2. The cover plate 9 and the storage groove 10 on the top of the second main body plate 2 are fitted together. The tight fit between the storage groove 10 and the cover plate 9 achieves a seal on the top of the packaging box, preventing dust and debris from entering the box. If it is necessary to divide the internal space of the box, the partition can be inserted into the sliding grooves 11 symmetrically opened on the inner sidewalls of the first main body plate 1 and the second main body plate 2. The sliding grooves 11 guide and limit the partition, and the position of the partition can be flexibly adjusted according to the size of the items. This system enables the categorization and storage of multiple items. In addition, the handles 12 on the outer walls of the first main board 1 and the second main board 2 are designed based on mechanical principles to provide force points for handling and reduce the difficulty of handling. The first main board 1, the second main board 2, the first bottom board 3, the second bottom board 4, the first side board 5, the second side board 6 and the cover board 9 are made of five layers of high-strength corrugated cardboard. Through the buffer and support structure of the multi-layer corrugated cardboard, the overall load-bearing capacity and impact resistance are improved. The anti-slip texture on the outer walls of the first main board 1 and the second main board 2 increases friction and prevents the packaging box from slipping out of your hands during handling.

[0050] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
