Description

Technical Field

[0001] This utility model relates to the technical field of packaging boxes, and in particular to a foldable and reusable packaging box. Background Technology

[0002] Precise crease planning, snap-fit ​​adaptation, and form transformation enable packaging to evolve from flat panels to three-dimensional containers. This not only fulfills basic functions such as product protection and display but also subtly considers storage, transportation, and user experience. The quick-folding assembly, as an optimized and upgraded solution for meaningful folding, offers multiple significant advantages. On the production side, its standardized folding logic adapts to automated production lines, significantly shortening assembly time and improving production efficiency, especially suitable for high-frequency shipping scenarios such as e-commerce order surges and holiday stocking. In logistics, the folded flat panels can significantly reduce storage space and transportation volume costs, while the sturdy folded structure reduces product damage during transport. In end-user scenarios, the simple and easy-to-understand folding steps lower the assembly threshold for merchants or consumers, allowing for quick packaging without specialized tools, enhancing ease of use. Therefore, a foldable and reusable packaging box is needed.

[0003] Existing foldable and reusable packaging boxes suffer from insufficient strength in the connections on both sides during use. When heavy objects are placed inside, the bottom splice plate is prone to slipping, and the sides are also prone to twisting and deformation. Although they are equipped with folding and installation components, in actual use, after multiple folding operations, the connection points of the components are easily worn, making it difficult to guarantee the stability and durability of the structure. This seriously affects the load-bearing capacity and reuse life of the packaging, and cannot meet the needs of high-frequency, heavy-duty usage scenarios.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN208897539U that discloses a folding packaging box. The patent proposes that "the first folded edge is designed to engage with the inner side of the cover when it is closed, reducing gaps between the cover and the left side panel, and between the cover and the right side panel, thus improving the box's sealing performance; it also prevents the cover from entering the box, making the box structure more stable. Since both the left and right side panels have first folded edges, considering the folding issue of the first folded edges, the third crease is designed to extend to the first folded edges, allowing the first folded edges to fold flat as the left and right side panels fold inward. To prevent the two first folded edges from interfering with each other when folded flat, the first folded edge includes outward-folding portions. These two outward-folding portions can fold flat in opposite directions on both sides when the left and right side panels fold flat, thus preventing interference between the two first folded edges and improving the flatness after folding." While this prevents interference between the two first folded edges and improves the flatness after folding, it only involves a single fold, resulting in poor fixation.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this invention is to provide a foldable and reusable packaging box to solve the problems mentioned in the background art, such as insufficient connection strength on both sides of existing foldable and reusable packaging boxes, easy slippage of the bottom splicing plate when holding heavy objects, and easy twisting and deformation of the sides. Although equipped with folding installation components, in actual use, after multiple folding operations, the component joints are easily worn, making it difficult to guarantee the stability and durability of the structure, seriously affecting the load-bearing capacity and reuse life of the packaging, and failing to meet the needs of high-frequency, heavy-load scenarios.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foldable and reusable packaging box, including a base plate, a first display plate connected to one side surface of the base plate, a card plate fixedly connected to one side surface of the first display plate, a first placement plate connected to one side surface of the base plate, a placement groove formed on one side surface of the first placement plate, a support frame provided on the upper surface of the base plate, a first card slot formed on one side surface of the support frame, a first partition plate provided on the inner surface of the support frame, a protective cover provided on the upper surface of the first display plate, and a presentation groove formed on one side surface of the protective cover.

[0008] Preferably, a second display board is connected to one side surface of the base plate, and both the second display board and the first display board are fixedly connected to a clamping plate. The clamping plates are arranged in two sets and are symmetrically distributed.

[0009] Preferably, a second placement plate is connected to one side surface of the base plate, and placement grooves are provided at both ends of the first placement plate and the second placement plate.

[0010] Preferably, a second slot is provided on one side surface of the support frame, and two sets of the first slot and the second slot are provided and symmetrically arranged.

[0011] Preferably, a first partition is provided on the inner surface of the first slot, a first connecting groove is provided on the upper surface of the first partition, a second partition is provided on the upper surface of the first connecting groove, and a second connecting groove is provided on one side surface of the second partition.

[0012] Preferably, a fixing block is fitted on the upper contact surface between the first display board and the first placement board, and a fixing block is fitted on the upper contact surface between the second display board and the second placement board.

[0013] Preferably, a handle is installed on the upper surface of the protective cover, and an elastic band is connected to the inner surface of the material tray.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the foldable and reusable packaging box; 1. The base plate can be removed by unscrewing the elastic band in the display slot, making the process convenient and preventing parts from scattering. For frame assembly, the first and second display panels are folded in half to quickly close the parts, utilizing the folding mechanism. The mounting plates on the display panels are then precisely inserted into the mounting slots on the mounting plates, achieving a stable connection. No additional fasteners are needed during assembly; the basic frame is built simply by fitting the components together. Subsequent reinforcement and partitioning operations are equally efficient: the support frame is placed directly on the base plate to enhance bottom load-bearing capacity; the fixing blocks are precisely engaged at the connections between the first and second display panels and the first and second mounting plates, respectively, to specifically reinforce the joint gaps. The first partition is fixed by aligning it with the first mounting slot, and the second partition is installed by aligning it with the second mounting slot and the second connecting slot. The installation of both partitions requires no adjustment or calibration, relying on the pre-set slot structure for precise positioning.

[0015] 2. Next, the first display panel, the second display panel, the first placement panel, and the second placement panel are joined together by the embedded splicing method of the placement slots of the card plate to form a tightly interlocking connection structure. Combined with the support frame to strengthen the load-bearing capacity of the base plate, and the fixing blocks to specifically reinforce the splicing gaps between the first display panel and the first placement panel, and between the second display panel and the second placement panel, a three-dimensional load-bearing frame with strong deformation resistance is constructed, which can stably support the internal items. The double partition design further enhances adaptability. The first partition is fixed by the first card slot, and the second partition is installed through the dual positioning of the second card slot and the second connecting slot. The two work together to flexibly divide the internal space to adapt to the storage needs of items of different sizes. The protective cover with handle can reliably close the box and prevent items from falling out. Attached Figure Description
