Description

Technical Field

[0001] This utility model belongs to the field of recyclable packaging technology, and specifically relates to a packaging structure. Background Technology

[0002] Currently, the packaging of home appliances such as wall-mounted air conditioners mainly uses a combination of corrugated cardboard boxes and cushioning pads. Corrugated cardboard boxes, due to their single-use nature, cause significant wood consumption and environmental pollution. To address this, the packaging industry has proposed reusable turnover box solutions, such as foldable turnover boxes. However, existing foldable turnover boxes mostly adopt a general design, failing to fully consider the structural characteristics and transportation requirements of specific products like wall-mounted air conditioners. This leads to problems in practical applications such as low assembly and disassembly efficiency, complex folding structures, and large empty box volume during recycling, increasing transportation and storage costs. Especially during recycling, unreasonable folding mechanism design results in inconvenient operation and low transportation efficiency. Utility Model Content

In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0021] In the description of this utility model, it should be clarified that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence; the terms "vertical," "lateral," "longitudinal," "front," "back," "left," "right," "up," "down," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model, and do not mean that the device or element referred to must have a specific orientation or position, and therefore should not be construed as a limitation of this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] This embodiment provides a packaging structure, such as Figures 1-10As shown, the packaging structure includes a first frame 1, a second frame 2, a first connecting unit 3, and a second connecting unit 4. The first end of the first frame 1 is connected to the first end of the second frame 2 through the first connecting unit 3, and the second end of the first frame 1 is connected to the second end of the second frame 2 through the second connecting unit 4, so that the first frame 1 and the second frame 2 enclose the packaging structure with a accommodating space.

[0024] The first frame 1 and the second frame 2 are two independent components, which are connected at specific locations by the first connecting unit 3 and the second connecting unit 4. More specifically, the first end of the first frame 1 is connected to the first end of the second frame 2 through the first connecting unit 3, while the second end of the first frame 1 is connected to the second end of the second frame 2 through the second connecting unit 4. This symmetrical connection ensures that the first frame 1 and the second frame 2 can tightly enclose a stable containing space, thereby forming a complete packaging structure.

[0025] The first frame 1 and the second frame 2 provide basic support and containment for the packaging structure. They constitute the main body of the packaging, carrying and protecting the internal products to ensure their safety during transportation and storage. The first connecting unit 3 and the second connecting unit 4 enable a detachable connection between the first frame 1 and the second frame 2. More specifically, they allow users to quickly and easily assemble and disassemble the packaging, thereby improving its usability and reusability, and reducing manual operation time.

[0026] The first frame 1 and the second frame 2 work together via the first connecting unit 3 and the second connecting unit 4. When assembling the packaging, the user simply connects the first connecting unit 3 to the first end of the first frame 1 and the second frame 2, and simultaneously connects the second connecting unit 4 to their second ends, thus firmly connecting the two frames to form a closed storage space. During disassembly, the user simply disconnects the first connecting unit 3 and the second connecting unit 4, allowing the first frame 1 and the second frame 2 to be easily separated, facilitating subsequent folding, storage, or transportation. This method of assembly ensures the efficiency and convenience of the packaging structure during use and recycling.

[0027] This embodiment solves the problems of low assembly and disassembly efficiency and large empty box volume during recycling of traditional packaging structures by cooperating the first frame 1, the second frame 2, the first connecting unit 3, and the second connecting unit 4. More specifically, because the first connecting unit 3 and the second connecting unit 4 adopt a detachable design, the assembly and disassembly process of the packaging structure is faster and simpler, reducing operational complexity and improving recycling efficiency. Furthermore, when the packaging structure needs to be recycled, the first frame 1 and the second frame 2 can be handled independently by disassembling the connecting units, thereby significantly reducing the total volume of the empty box and lowering transportation and storage costs. This design optimizes practicality and economy for the packaging needs of products such as wall-mounted air conditioners.

[0028] In a specific embodiment, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 10 As shown, the first frame 1 includes a first base plate 11 and a first side plate 12, which are rotatably connected by a first rotating unit 5; the second frame 2 includes a second base plate 21 and a second side plate 22, which are rotatably connected by a second rotating unit.

[0029] The first frame 1 consists of a first base plate 11 and a first side plate 12, which are rotatably connected by a first rotating unit 5. This means that the first side plate 12 can rotate relative to the first base plate 11, thereby changing the angle and position of the frame. Similarly, the second frame 2 consists of a second base plate 21 and a second side plate 22, which are rotatably connected by a second rotating unit, allowing the second side plate 22 to rotate relative to the second base plate 21. This design allows the entire packaging structure to adjust its shape through rotation. More specifically, this rotatable connection allows the first side plate 12 and the second side plate 22 to fold inward onto the first base plate 11 and the second base plate 21 when not in use, thereby significantly reducing the overall size of the packaging structure and saving space during recycling or storage. Furthermore, this simple rotating mechanism simplifies the assembly and disassembly process. Users do not need complicated tools or steps; they can quickly assemble or disassemble the frame simply by manually rotating it. This not only improves operational efficiency but also reduces problems caused by component misalignment or damage, thereby enhancing the practicality and durability of the packaging structure. It also supports multiple reuses, reduces overall costs, and improves environmental benefits.

[0030] In a specific embodiment, such as Figure 5 and Figure 6As shown, the first connecting unit 3 includes a first plug-in portion 31 and a first snap-fit ​​portion 32. The first plug-in portion 31 is disposed at the first end of the first frame 1, and the first snap-fit ​​portion 32 is disposed at the first end of the second frame 2. The first plug-in portion 31 and the first snap-fit ​​portion 32 are detachably engaged. The second connecting unit 4 includes a second plug-in portion 41 and a second snap-fit ​​portion 42. The second plug-in portion 41 is disposed at the second end of the first frame 1, and the second snap-fit ​​portion 42 is disposed at the second end of the second frame 2. The second plug-in portion 41 and the second snap-fit ​​portion 42 are detachably engaged.

[0031] The first connecting unit 3 includes a first plug-in portion 31 and a first snap-fit ​​portion 32. The first plug-in portion 31 is disposed at the first end of the first frame 1, and the first snap-fit ​​portion 32 is disposed at the first end of the second frame 2. The detachable engagement of the first plug-in portion 31 and the first snap-fit ​​portion 32 enables quick connection and separation of the first frame 1 and the second frame 2 at the first end. Similarly, the second connecting unit 4 includes a second plug-in portion 41 and a second snap-fit ​​portion 42. The second plug-in portion 41 is disposed at the second end of the first frame 1, and the second snap-fit ​​portion 42 is disposed at the second end of the second frame 2. The detachable engagement of the second plug-in portion 41 and the second snap-fit ​​portion 42 enables a stable connection and easy disassembly of the first frame 1 and the second frame 2 at the second end. More specifically, this design of the plug-in and snap-fit ​​portions allows users to assemble or disassemble the frames through simple plugging and unplugging actions, without the need for additional tools or complex operations, thereby significantly improving the efficiency of assembly and disassembly. Furthermore, this detachable joining mechanism facilitates the quick separation of frame components during recycling, allowing the packaging structure to be folded and stored more compactly, reducing space occupation and lowering transportation and storage costs. At the same time, the ease of component replacement extends the overall structure's lifespan, enhancing the economy and environmental friendliness of recycling.

[0032] In a specific embodiment, such as Figure 7 and Figure 10 As shown, the first rotating unit 5 includes a first rotating shaft 51 and a first shaft hole 52. The first rotating shaft 51 is disposed on the first base plate 11, and the first shaft hole 52 is disposed on the first side plate 12. The first rotating shaft 51 and the first shaft hole 52 cooperate to enable the first side plate 12 to rotate around the first rotating shaft 51. The second rotating unit includes a second rotating shaft and a second shaft hole. The second rotating shaft is disposed on the second base plate 21, and the second shaft hole is disposed on the second side plate 22. The second rotating shaft and the second shaft hole cooperate to enable the second side plate 22 to rotate around the second rotating shaft.

[0033] The first rotating unit 5 achieves its function through the cooperation of a first rotating shaft 51 and a first shaft hole 52. The first rotating shaft 51 is disposed on the first base plate 11, while the first shaft hole 52 is disposed on the first side plate 12. When the first shaft hole 52 is fitted onto the first rotating shaft 51, the first side plate 12 can rotate smoothly around the first rotating shaft 51. Similarly, the second rotating unit adopts a corresponding structure, consisting of a second rotating shaft disposed on the second base plate 21 and a second shaft hole disposed on the second side plate 22. The cooperation between the second shaft hole and the second rotating shaft allows the second side plate 22 to rotate around the second rotating shaft. This direct cooperation between the rotating shaft and the shaft hole constitutes a simple and reliable rotating mechanism. More specifically, this mechanical connection method ensures the stability of the side plate during rotation, avoids unnecessary shaking or dislocation during use, and makes the entire folding action both smooth and stable. Furthermore, this design explicitly distributes the rotating components on the base and side plates, simplifying the structural complexity of individual parts. This not only facilitates manufacturing but also allows for targeted replacement of damaged side or base plates after long-term use if a rotating component wears out, without scrapping the entire packaging structure. This significantly improves the convenience and economy of maintenance. From an overall perspective, this specific rotating unit is the core of enabling rapid folding and unfolding of the packaging box. It directly solves the problem of high transportation and storage costs caused by excessively large empty boxes during recycling. Simultaneously, its durability and ease of maintenance further support the long-term reuse of the packaging box, aligning with the principles of environmental protection and conservation.

[0034] In a specific embodiment, such as Figure 4 As shown, the packaging structure also includes multiple pads 6. The first base plate 11 and the second base plate 21 are both provided with limiting grooves 111, and the pads 6 are correspondingly disposed in the limiting grooves 111.

[0035] The packaging structure also includes multiple pads 6, which act as cushioning components to protect the internal product. Both the first base plate 11 and the second base plate 21 are designed with limiting grooves 111, within which the pads 6 are correspondingly placed. The contour of the limiting groove 111 matches the shape of the pads 6, ensuring the pads 6 are fixed in position on the base plate. More specifically, the depth and dimensions of the limiting groove 111 are designed to tightly accommodate the edges of the pads 6, preventing lateral or longitudinal movement during transportation due to vibration or impact. Furthermore, this arrangement creates a stable connection between the pads 6 and the base plate, improving the overall compactness of the packaging and ensuring accurate product positioning within the box, thereby effectively reducing the risk of product collision or damage due to pad displacement. In terms of effectiveness, the design of the limiting groove 111 directly solves the problem of packaging pads easily shifting during transportation, enhancing the reliability and safety of the packaging. At the same time, since the pads 6 are firmly fixed, it also simplifies the packing and unpacking operations, improves work efficiency, supports multiple cycles of the packaging structure, and extends its service life.

[0036] In a specific embodiment, the first base plate 11, the first side plate 12, the second base plate 21 and the second side plate 22 are each provided with a plurality of reinforcing ribs 112, and the reinforcing ribs 112 are distributed along the stress direction of the packaging structure.

[0037] In this embodiment, as Figure 5 As shown, the first base plate 11, the first side plate 12, the second base plate 21, and the second side plate 22 are all provided with multiple reinforcing ribs 112. These reinforcing ribs 112 are not randomly arranged, but are distributed along the direction in which the packaging structure mainly bears external forces during transportation. For example, when stacking vertically, the reinforcing ribs 112 are arranged along the direction of gravity, while during horizontal handling, they are arranged along the direction of compression resistance. More specifically, this distribution method allows the reinforcing ribs 112 to effectively distribute and bear the load from external pressure or impact, thereby enhancing the local rigidity and overall stability of the first base plate 11, the first side plate 12, the second base plate 21, and the second side plate 22. Furthermore, by uniformly distributing reinforcing ribs 112 on all major components, the packaging structure can resist deformation and wear during repeated use, significantly improving its load-bearing capacity and anti-clamping performance during handling, ultimately extending the service life of the packaging structure, reducing the risk of damage due to insufficient strength, and supporting the economic and environmental benefits of recycling.

[0038] In a specific embodiment, the reinforcing ribs 112 are symmetrically arranged on the first base plate 11, the first side plate 12, the second base plate 21, and the second side plate 22.

[0039] The reinforcing ribs 112 are symmetrically arranged on the first base plate 11, the first side plate 12, the second base plate 21, and the second side plate 22. This means that the arrangement of the reinforcing ribs 112 forms a mirror or balanced layout on the corresponding components of the box. For example, the distribution of the reinforcing ribs 112 on the first base plate 11 corresponds to the distribution on the second base plate 21, and a similar symmetrical pattern is maintained on the first side plate 12 and the second side plate 22. More specifically, this symmetry ensures that when the packaging structure is subjected to external pressure, such as the squeezing force during handling, the force can be evenly distributed to each symmetrical point, avoiding overload or deformation in local areas, thereby improving the stability and consistency of the overall structure. Furthermore, the symmetrically arranged reinforcing ribs 112 help maintain the shape integrity of the box during repeated use, reducing wear or damage caused by asymmetrical forces, making the packaging structure more resistant to deformation during transportation and storage, and enhancing its anti-clamping performance and stacking strength. This design not only improves the reliability and durability of the packaging but also supports multiple cycles of use, reducing replacement frequency and maintenance costs.

[0040] In a specific embodiment, the packaging structure further includes a heat-shrinkable film, which is wrapped around the outside of the first frame 1 and the second frame 2.

[0041] The packaging structure also includes a heat-shrinkable film. After assembly, this film is completely wrapped around the outside of the first frame 1 and the second frame 2, and is heat-treated to shrink it, thus tightly adhering to the outer surface of the frame assembly. More specifically, this film forms an additional binding layer, further securing the first frame 1 and the second frame 2 together at the joint of the first connecting unit 3 and the second connecting unit 4, enhancing the overall structural stability and effectively preventing the frame connections from loosening or coming apart due to vibration or accidental collisions during handling or transportation. This heat-shrinkable film acts as a physical barrier, preventing external dust, moisture, or other contaminants from entering the packaging, providing additional dust and moisture protection for the products inside the box. This is crucial for ensuring the cleanliness and integrity of household appliances such as wall-mounted air conditioners during distribution. This simple yet effective wrapping method not only enhances the overall integrity and security of the packaging structure, enabling it to better cope with complex logistics environments, but also provides an additional layer of reliability for reusable packaging without significantly increasing costs and operational complexity, due to the low cost and ease of application and removal of the film itself. It also facilitates inspection during recycling, allowing for timely replacement of damaged film to maintain the integrity of the packaging for the next use.

[0042] In a specific embodiment, the first side plate 12 can be rotated 90 degrees from the unfolded state to the folded state by the first rotation unit 5, and the second side plate 22 can be rotated 90 degrees from the unfolded state to the folded state by the second rotation unit.

[0043] The first side panel 12 can be rotated 90 degrees from its fully unfolded, vertical position for packaging to a folded state parallel to the first base panel 11 via the first rotating unit 5. Similarly, the second side panel 22 can also be rotated 90 degrees from its unfolded position to a folded state tightly fitted with the second base panel 21 via the second rotating unit. This 90-degree rotation angle is designed to allow the side panels to complete the transformation from use to storage with the most direct and efficient path and minimal operating space. Users only need to apply a simple rotation action to achieve this, without complicated steps or additional operating space. Furthermore, when both the first side panel 12 and the second side panel 22 are rotated 90 degrees and folded onto their respective base panels, the overall thickness of the entire packaging structure is significantly reduced. The originally three-dimensional box becomes a compact, almost flat shape, which greatly optimizes the space utilization of the empty box during recycling and storage. This clear and efficient 90-degree folding mechanism directly solves the core problem of excessive volume occupied by turnover boxes when empty during the cycle of use, making the storage and transportation of empty boxes more economical and significantly reducing related logistics costs. At the same time, its intuitive and simple operation method also improves the user experience.

[0044] In a specific embodiment, when both the first connecting unit 3 and the second connecting unit 4 are in the engaged state, the first side plate 12 and the second side plate 22, together with their respective limiting grooves 111, form a lateral limiting for the pad 6.

[0045] When both the first connecting unit 3 and the second connecting unit 4 are engaged, the first side plate 12 and the second side plate 22, together with their respective limiting grooves 111, form a lateral limiting effect on the pad 6. This means that the pad 6 is not only fixed from below by the limiting groove 111 at the bottom, but also surrounded from the sides by the upright first side plate 12 and the second side plate 22, thereby constraining the position of the pad 6 in multiple directions. More specifically, this lateral limiting mechanism, through the synergistic effect of the side plates and the limiting grooves 111, ensures that the pad 6 cannot move laterally, longitudinally, or rotationally within the packaging structure. Even if bumps or vibrations occur during transportation, the pad 6 can remain in its original position. Furthermore, this comprehensive fixing method enhances the overall compactness and stability of the packaging, preventing collisions or abrasions to internal products such as wall-mounted air conditioners due to the displacement of the pad 6, thereby effectively protecting the appearance and internal structure of the product. In terms of effectiveness, this design directly solves the problem of packaging liners shifting during transportation, improving the reliability and safety of the packaging. At the same time, because the liner 6 is firmly fixed, it also simplifies the loading and unloading process, supports multiple recycling of the packaging structure, reduces maintenance needs and overall costs, and ultimately achieves better environmental benefits and usage efficiency.

[0046] The packaging structure begins in its folded state, where the first side panel 12 is folded parallel to the first base plate 11 via the first rotating unit 5, and the second side panel 22 is also folded parallel to the second base plate 21 via the second rotating unit. When packaging a product, the user first rotates the first side panel 12 and the second side panel 22 90 degrees from their respective base plates to unfold them into a vertical position, forming two independent, L-shaped open frames. More specifically, the user then places multiple cushioning pads 6 into the pre-set limiting grooves 111 on the first base plate 11 and the second base plate 21, and then securely places products such as wall-mounted air conditioners on the support platform formed by these two frames, with the product protected by the cushioning pads 6 on both sides.

[0047] Next, the user brings the first frame 1 and the second frame 2 closer together, so that the first insertion part 31 at the first end of the first frame 1 engages with the first snap-fit ​​part 32 at the first end of the second frame 2, and simultaneously engages the second insertion part 41 at the second end of the first frame 1 with the second snap-fit ​​part 42 at the second end of the second frame 2, thereby firmly combining the two frames into a complete box body surrounded by the first side plate 12 and the second side plate 22. At this time, the upright first side plate 12 and the second side plate 22 work together with the limiting groove 111 at the bottom to form a complete lateral limit on the pad 6, effectively preventing it from moving.

[0048] Furthermore, to enhance the overall rigidity and dust and moisture resistance of the packaging, users can wrap heat-shrink film around the assembled first frame 1 and second frame 2. After heating, the film shrinks and tightens, making the entire packaging structure integrated. During transportation and stacking, the reinforcing ribs 112 distributed on the first base plate 11, first side plate 12, second base plate 21, and second side plate 22, especially their symmetrical arrangement, work together to withstand external pressure and ensure structural stability.

[0049] When the product is delivered and needs to be removed, the packaging structure can be recycled. The recycling process is carried out in reverse: remove or cut the heat-shrink film, disconnect the connection between the first connecting unit 3 and the second connecting unit 4, separate the two frames, and then rotate the first side plate 12 and the second side plate 22 90 degrees again and fold them to the bottom plate to achieve small-volume storage and transportation of the empty box, completing one cycle.
