Description

Technical Field

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

[0002] Foldable packaging boxes are packaging containers made of foldable materials such as paper and plastic. Through pre-designed creases and folding structures, they can be stored flat to save space when not in use. When in use, they can be folded and assembled to form a complete packaging container. They are widely used in food, electronics, cosmetics, and other fields. Their core value lies in balancing packaging functionality and logistical economy. They are quick to disassemble, allowing users to easily disassemble the packaging box into a flat shape or separate different material components without the need for tools such as scissors or knives. This design not only improves the user experience but also solves the problems of laborious disassembly and easy hand injury from traditional packaging boxes. Furthermore, it responds to environmental protection requirements: the disassembled flat materials are easier to classify and recycle, reducing the difficulty of recycling and sorting caused by complex structures. Therefore, a foldable packaging box that can be quickly assembled is needed.

[0003] Existing quick-assembly folding packaging boxes, while emphasizing rapid assembly, suffer from poor stability after assembly, are prone to loosening, and struggle to maintain their fixed shape. Furthermore, the packaging boxes do not provide sufficient support and protection for the products inside, failing to offer reliable support and protection.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN205169122U that discloses a detachable foldable packaging box. The patent states that it utilizes magnetic attraction for excellent fastening, easy molding, and a flat and aesthetically pleasing appearance. Furthermore, disassembly ensures no damage to the original structure and shape, maximizing flatness and saving space for storage and transportation. When used as catering packaging, the bottom box can be completely flattened. Since the bottom box is a single piece, it can be laid flat and used as a tablecloth for dining, facilitating meals and achieving functional reuse. The lid and body can be freely separated. The fastening mechanism uses magnets for all components, ensuring a tight fit, a flat and aesthetically pleasing appearance, and minimal space and visual clutter. Compared to folding or adhesive corner fasteners, magnetic attachment allows for more thorough and convenient disassembly and reassembly. Because it unfolds completely flat, it effectively prevents deformation from compression, saves space, and is easy to stack, making it more convenient and cost-effective for transportation. However, while it effectively prevents deformation from compression, saves space, and is easy to stack, making it more convenient and cost-effective for transportation, it can only withstand relatively low pressure without deformation, and the magnetic fasteners may be affected by nearby magnetic fields during transport.

[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 utility model is to provide a foldable packaging box that can be quickly assembled, in order to solve the problems mentioned in the background art. Existing foldable packaging boxes that can be quickly assembled have poor stability after assembly, are prone to loosening, and are difficult to maintain a fixed shape. At the same time, the packaging box does not provide enough fixation for the internal products and cannot provide reliable support and protection for the products.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foldable packaging box that can be quickly assembled, comprising a base plate, a first connecting plate rotatably connected to one side surface of the base plate, a T-slot formed on one side surface of the first connecting plate, a first placement plate provided on one side surface of the first connecting plate, a filling plate provided on the upper surface of the base plate, a connecting cover rotatably connected to one side surface of the second placement plate, a fixing block fixedly connected to one side surface of the connecting cover, placement grooves formed on both sides of the fixing block, a fixing sleeve fixedly connected to the inner surface of the placement groove, a connecting rod penetratingly connected to one side surface of the fixing sleeve, a pressing block fixedly connected to one side surface of the connecting rod, a handle fixedly connected to the upper surface of the connecting cover, and elastic bands connected to both sides of the base plate.

[0008] Preferably, a second connecting plate is rotatably connected to one side surface of the base plate, and a T-slot is formed on one side surface of the second connecting plate.

[0009] Preferably, the inner surface of the T-slot is provided with a first placement plate and a second placement plate.

[0010] Preferably, the inner surfaces of the first placement plate and the second placement plate are provided with a first card plate, the lower part of the first card plate is provided with a first card slot, the upper surface of the first card plate is provided with a second card plate, and the upper surface of the second card plate is provided with a second card slot.

[0011] Preferably, a connecting block is fixedly connected to the upper surface of the first placement plate, and a fixing groove is formed through one side surface of the connecting block.

[0012] Preferably, a stop piece is fixedly connected to one end surface of the connecting rod, and a limit block is fixedly connected to the outer surface of the stop piece.

[0013] Preferably, a limiting groove is formed on the inner surface of the fixing sleeve, a spring is fixedly connected to one side surface of the abutment, and the abutment and limiting block slide inside the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the foldable packaging box that can be quickly assembled;

[0015] 1. First, the elastic band is stored away to make room for subsequent operations. Then, the first and second connecting plates are unfolded on the base plate to quickly build the basic support frame of the packaging box. Next, the positioning function of the T-slot is used to precisely align and install the first and second placement plates to further enhance the stability of the frame. Then, the internal structure of the main body is improved by laying the filling plate. The entire main body assembly process does not require additional tools and can be completed solely by the adaptation relationship between the components. The subsequent operation of the connecting cover also revolves around the dedicated components: pull the handle to unfold the connecting cover, install the second card plate in place, and insert the first card plate into the second card slot for adaptation. Each step has a clear component as the core of the operation. The process is free of redundancy and the connection is smooth, which greatly reduces the complexity of operation. Assembly can be completed without the help of complicated tools, which greatly reduces the difficulty of operation. Even first-time users can quickly master it and significantly improve the assembly efficiency.

[0016] 2. The base plate, as the basic load-bearing component, provides stable support for the unfolding of the first and second connecting plates. Together with the first and second placement plates installed through the T-slots, they form a three-dimensional frame structure, effectively improving the overall load-bearing capacity and resistance to deformation. The filler plate is laid on the base plate to further fill the structural gaps, enhancing the integrity and stability of the main body. In the closing and fixing process of the connecting cover, the linkage mechanism formed by multiple components achieves precise locking: after pressing the pressing block, it drives the abutment and the limiting block to slide inside the limiting groove through the connecting rod and squeeze the spring, so that the pressing block is fully inserted into the placement groove. At this time, the connecting cover can be rotated to the top of the first placement plate. When the fixing block and the connecting block are aligned, the spring's rebound force is transmitted to the pressing block through the abutment and the connecting rod, accurately sending it into the fixing groove, completing the stable fixing of the connecting cover. The entire structure, from the main frame to the closing and locking, is achieved through the adaptation and linkage of components, which not only ensures the structural strength after assembly but also makes the closing and fixing process efficient and not easy to loosen.
