Description

Technical Field

[0001] The invention relates to the technical field of packaging boxes, in particular to a plastic packaging box. Background Art

[0002] With the rapid development of logistics, warehousing and retail industries, the demand for plastic packaging boxes is growing. For example, a panel box composed of a pallet, a box body, a box cover, and more than one section of panels in a stacked manner (as shown in Figures 1-2) has gradually attracted widespread attention due to its portability through folding and small space occupation when not in use. However, it still seems to be unable to cope with diversified and personalized packaging needs, especially when it comes to transit goods that need to be stored in a classified manner. Traditional plastic packaging boxes often cannot provide sufficient flexibility and adaptability. For this reason, we propose a plastic packaging box. Summary of the invention

[0003] A technical problem to be solved by this application is to provide an efficient and convenient packaging solution for the logistics, warehousing and retail industries by flexibly dividing the space inside the box, improving the utilization rate of storage space and adapting to the storage needs of different commodities.

[0004] In order to solve the above technical problems, the embodiment of the present application provides a plastic packaging box, including a base, a cover plate, a panel-type box body composed of two fixed side panels and two folding side panels, and also includes: The upper and lower layer partition units are fixed on the inner side of any fixed side panel, and after being stretched and fixed to the other fixed side panel, the interior of the box is divided into multiple independent areas from top to bottom; The longitudinal partition unit is installed on the inner side of the fixed side plate facing the upper and lower layer partition unit, and after being extended and fixed to another fixed side plate, the box body is longitudinally divided into multiple independent areas; The grid-type partition unit is installed on any fixed side plate. After being stretched and fixed to the other fixed side plate, the interior of the box is longitudinally divided into multiple independent units in a grid-type manner. When the upper and lower layer separation units and the longitudinal separation units are extended at the same time, the interior of the box is divided into upper and lower layers and each layer is divided into a plurality of independent areas.

[0005] In some embodiments, the upper and lower layer separation unit includes a plurality of horizontal cross braces installed in an upper and lower and left and right interval manner on the fixed side panel, and a fixing piece is provided at one end of the horizontal cross brace. After the cross brace is unfolded, the fixing piece is used to fix it to another fixed side panel.

[0006] In some embodiments, the horizontal cross brace includes a plurality of transverse rods and cross rods movably mounted between the transverse rods, and a guide bar is arranged at the side edge of the folding side plate, and the end of the transverse rod slides inside the guide bar; A sleeve is slidably sleeved on the end of the transverse rod, and the sleeve is slidably sleeved on the ends of the left and right adjacent transverse rods, thereby increasing the overall layer separation strength.

[0007] In some embodiments, the longitudinal partition unit includes a plurality of vertical cross braces installed at intervals on the fixed side panels, and the ends of the vertical cross braces are also provided with fixings. After the vertical cross braces are unfolded and fixed with the fixings, the box is divided longitudinally.

[0008] In some embodiments, the vertical cross brace 2 corresponds to the gaps between adjacent horizontal cross braces 1 on a one-to-one basis and is located exactly between two adjacent horizontal cross braces 1.

[0009] In some embodiments, a plurality of guide rail seats corresponding to the guide rails are arranged at the side positions of the vertical cross brace 2, and the ends of the transverse rods slide inside the guide rail seats to provide auxiliary support for the transverse rods.

[0010] In some embodiments, the grid partition unit includes a plurality of adjacent left and right, front and back partitions, and vertical cross braces are arranged between the adjacent front and back partitions and between the outermost partition and the fixed side panel, and fixings are also arranged between the other fixed side panel and the opposite partition. After the partition is unfolded, the vertical cross braces and the partition are used to grid the internal space of the box.

[0011] In some embodiments, the fixing member includes bolts, and screw holes are provided at corresponding positions on the fixing side plate to achieve detachable fixing.

[0012] In some embodiments, mounting plates are detachably fixed to the inner sides of the two fixed side panels, and the upper and lower layer separation units, the longitudinal partition units and the grid-type mesh units are respectively arranged on the two fixed side panels.

[0013] The present invention has at least the following beneficial effects: 1. High spatial flexibility: Through the combined use of upper and lower layer separation units, longitudinal separation units and grid separation units, this plastic packaging box can flexibly divide the internal space into multiple independent areas as needed. This design enables the box to adapt to the storage needs of items of different shapes, sizes and quantities, greatly improving the space utilization rate, and all designs do not affect the normal folding and stretching of the overall coaming box; 2. Convenient assembly and disassembly: All partition units are fixed by fixings, which are a combination of bolts and screw holes, so that users can quickly assemble and disassemble them according to their needs. This design not only improves the convenience of the packaging box, but also enables it to adapt to different logistics, warehousing and transportation needs; 3. Enhanced structural stability: The design of horizontal cross brace 1 and vertical cross brace 2 enhances the structural stability of the packaging box, especially the sliding design of the transverse rod in the guide bar and the guide seat, which not only facilitates assembly, but also improves the load-bearing capacity and anti-deformation ability of the packaging box through additional support points.
