Description

Technical Field

[0001] This utility model relates to the technical field of packaging boxes, and in particular to a packaging box that is easy to repeatedly disassemble and reassemble. Background Technology

[0002] Wooden crates, as a traditional form of packaging, still play an important role in modern logistics, transportation, and warehousing. With their high strength, wide adaptability, and customizability, they remain an irreplaceable choice in heavy industry, art transportation, and cross-border logistics.

[0003] In related technologies, packaging boxes used for heavy-duty packaging are mostly fixed with nails, bolts, or metal corner brackets. Disassembly and assembly require tools and rely on manual labor, resulting in low efficiency and high labor input. After repeated disassembly and assembly, the structural strength of the packaging box decreases, making it difficult to guarantee stability for multiple uses. Furthermore, after disassembly, the box material is prone to cracking, deformation, or failure of connectors. At the same time, friction between the box and the cargo during loading and unloading causes the box to move and shake, further damaging the structural stability of the packaging box. This leads to a decrease in structural stability, reduces the recycling rate and economy of the packaging box, affects transportation safety, and increases packaging costs. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a packaging box that is easy to disassemble and reassemble. It adopts multi-point insertion and limiting to improve the convenience of disassembly and assembly, reduce the labor intensity of workers, and improves the connection stability by combining bolt secondary tightening. It reduces structural damage caused by repeated disassembly and assembly, facilitates loading and unloading of goods, maintains the overall structural strength of the packaging box, improves transportation safety, realizes the recycling of the packaging box, and reduces packaging costs.

[0006] To achieve the above objectives, this utility model proposes a packaging box that is easy to repeatedly disassemble and reassemble, comprising a box body, a top cover, two sets of symmetrically arranged positioning mechanisms, a buffer limiting component, and a support component.

The support tube is disposed on the box body, the connecting component is disposed on the top cover, and the fastening component is movably connected to the connecting component and extends into the support tube through the connecting component, and is movably connected to the support tube.

[0007] This utility model discloses a convenient and reusable packaging box designed for the recycling of heavy cargo packaging. Two sets of symmetrically arranged positioning mechanisms quickly and precisely connect the top cover to the box body, reducing structural damage to the box body and top cover during disassembly and assembly. This facilitates cargo movement, reduces friction with the box body, and decreases labor intensity for workers. The secondary positioning of the connecting and fastening components maintains the integrity and stability after disassembly and assembly, improving transportation safety. It effectively increases the number of times the box body and top cover can be disassembled and assembled, enhancing the recycling rate of the packaging box and reducing packaging costs.

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0024] The following description, in conjunction with the accompanying drawings, describes a packaging box that is convenient for repeated assembly and disassembly according to an embodiment of the present invention.

[0025] like Figures 1-6 As shown, the packaging box of this utility model embodiment that is convenient to be repeatedly disassembled and reassembled may include a box body 1, a top cover 2, two sets of symmetrically arranged positioning mechanisms 3, a buffer limiting component 4, and a support component 5.

[0026] The top cover 2 is movably connected to the box body 1 through two sets of symmetrically arranged positioning mechanisms 3, the buffer limiting component 4 is set on the box body 1, and the support component 5 is set on the box body 1.

[0027] It should be noted that the housing 1 can stably support the two sets of symmetrically arranged positioning mechanisms 3, buffer limiting components 4 and support components 5, while the upper cover 2 is stably connected to the housing 1 through the two sets of symmetrically arranged positioning mechanisms 3.

[0028] The positioning mechanism 3 includes a support tube 31, a connecting component 32, and a fastening component 33.

[0029] The support tube 31 is disposed on the housing 1, the connecting component 32 is disposed on the upper cover 2, the fastening component 33 is movably connected to the connecting component 32, and extends into the support tube 31 through the connecting component 32 and is movably connected to the support tube 31.

[0030] It should be noted that the support tube 31 is supported on the ground, the connecting component 32 is inserted into the support tube 31, and is limited inside the support tube 31 by the fastening component 33, so as to realize the quick assembly and disassembly of the top cover 2.

[0031] Specifically, during the actual disassembly and assembly process, relevant personnel select a box 1 that matches the volume of the heavy goods. In the initial state, the box 1 and the top cover 2 are separated. A forklift is used to transport the goods to the vicinity of the box 1. The support component 5 carries the goods and moves along the length of the box 1 to load the goods into the box 1, avoiding pushing the box 1 when the goods move and reducing structural damage to the box 1. At the same time, the buffer limiting component 4 supports and limits the outside of the goods to prevent hard contact with the box 1.

[0032] After the goods are loaded, the top cover 2 is fastened to the box body 1 by two sets of symmetrically arranged positioning mechanisms 3. The fastening component 33 is pressed to make it fit with the connecting component 32. The connecting component 32 and the fastening component 33 are then inserted into the support tube 31. The fastening component 33 is released to allow it to automatically reset and fasten with the support tube 31, thus achieving rapid positioning of the top cover 2. The connecting component 32 is then further bolted to the support tube 31 to lock the top cover 2, enabling rapid packaging of the goods. This effectively improves the convenience of fastening the top cover 2 to the box body 1, reduces the labor intensity of the staff, enables repeated disassembly and reassembly of the packaging box, and reduces structural damage to the box body 1.

[0033] If it is necessary to remove the top cover 2, loosen and remove the locking bolts, and push the connecting plate 331 towards the side of the insert plate 322 to separate the positioning teeth 333 from the limiting block 312, and pull the top cover 2 upward through the connecting frame 321 to separate the top cover 2 from the box body 1.

[0034] In one embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the support tube 31 is provided with screw holes 311, and multiple limiting blocks 312 are provided inside the support tube 31.

[0035] It should be noted that multiple limiting blocks 312 are arranged sequentially along the height direction of the support tube 31 to limit the connection between the fastening component 33 and the support tube 31. The screw hole 311 is used to lock the connection between the support tube 31 and the connecting component 32, further improving the connection stability between the top cover 2 and the box 1.

[0036] In one embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the connecting component 32 includes a connecting frame 321, a insert plate 322, and a locking stud 323.

[0038] It should be noted that the locking stud 323 extends downward to lock the insert plate 322 inside the support tube 31 and fix the position of the fastening assembly 33.

[0039] In one embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the fastening assembly 33 includes a connecting plate 331, a torsion spring 332, and a plurality of positioning teeth 333.

[0040] The connecting plate 331 is movably connected to the insert plate 322 via a torsion spring 332, and multiple positioning teeth 333 are provided on the connecting plate 331 and engage with the limiting block 312.

[0041] It should be noted that, in the above embodiment, one end of the connecting plate 331 is rotatably connected to the side wall of the insert plate 322 via a rotating shaft, and a torsion spring 332 provides rotational force, so that the connecting plate 331 and the insert plate 322 form an angle and approach the limiting block 312, so that multiple positioning teeth 333 engage with multiple limiting blocks 312, thereby realizing the quick connection of the upper cover 2.

[0042] In one embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 5 As shown, the buffer limiting component 4 includes an airbag cushion 41, two sets of symmetrically arranged support bars 42, and two symmetrically arranged airbag columns 43.
