Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and in particular to a mortise and tenon structure non-adhesive corrugated packaging box. Background Technology

[0002] With the continuous expansion of my country's new energy vehicle production, related industries have also developed year by year, especially new energy vehicle batteries, which are one of the fastest-growing sectors in recent years.

[0003] Batteries used in new energy vehicles are characterized by their regular shape, large mass, and the need to avoid collisions. Therefore, when transporting these batteries, they need to be placed in a packaging box. To save space, multiple packaging components can be set inside the packaging box. Each packaging component has a positioning groove that matches the outer contour of the battery. Simply place the battery into the positioning groove.

[0004] For cost reasons, corrugated cardboard is traditionally used to make packaging components. The various components in the packaging components are made of multiple pieces of cardboard stacked and glued together. This results in a large amount of manual labor required to make the packaging components, which affects production efficiency. At the same time, these components are also fixed to the base plate of the packaging components by gluing. Therefore, the packaging components cannot be adjusted or changed after gluing. When the specifications of the batteries to be packaged change, a completely new packaging component that matches the size of the current batteries needs to be replaced, which to some extent causes waste and increases production and operating costs.

[0005] Therefore, a method or apparatus is needed to solve the above problems. Utility Model Content

[0006] This utility model aims to overcome the aforementioned shortcomings of the existing technology by proposing a mortise and tenon structure for adhesive-free corrugated packaging boxes that are simple in structure, ingenious in design, reasonable in layout, low in cost, easy to operate, and capable of quickly switching between different components according to actual needs.

[0007] The technical solution of this utility model is: a mortise and tenon structure non-adhesive corrugated packaging box, characterized in that: the packaging box includes a tray 1, a box body 2 that is open at both ends is provided on the tray 1, a top cover 3 is provided at the top opening of the box body 2, and multiple stacked packaging components 4 are provided inside the tray 1. Said packaging assembly 4 comprises a base plate 5, two sets of symmetrically distributed base plate square holes 6 are arranged on said base plate 5, said packaging assembly 4 further comprises two top plates with identical structures, the cross section of each top plate is in a mountain shape, which consists of an X-axis portion 7 distributed along the X-axis direction and three Y-axis portions 8 perpendicular to the X-axis portion 7, and the three Y-axis portions 8 are distributed at equal intervals in the length direction of the X-axis portion 7, three connecting limit blocks 9 are further connected to the base plate 5, and the connecting limit blocks 9 are located between the two opposite Y-axis portions 8, Said top plate and the three connecting limit blocks 9 jointly enclose to form two limit frames, two pairs of cushion blocks 10 are further arranged on said base plate 5, and the two pairs of cushion blocks 10 are respectively located in the two limit frames, Top plate square holes 11 are opened on said Y-axis portion 8, and the top plate is fixedly connected to the base plate 5 through three T-shaped latches 12 that pass through the top plate square holes 11 and the base plate square holes 6, Said top plate is composed of a plurality of top plate pieces 13 with identical structures.

[0008] Said base plate 5 is composed of a plurality of base plate pieces 14 with identical structures, and adjacent base plate pieces 14 are bonded to each other.

[0009] An insertion portion 15 is arranged on the bottom end face of said connecting limit block 9, and the insertion portion 15 can be inserted into a connection socket 16 opened on the base plate 5.

[0010] An insertion portion 15 is arranged on the bottom end face of said cushion block 10, and the insertion portion 15 can be inserted into a connection socket 16 opened on the base plate 5.

[0011] Said connecting limit block 9, cushion block 10 and T-shaped latch 12 are all formed by folding corrugated paperboard.

[0012] Compared with the prior art, the present utility model has the following advantages: This type of mortise and tenon structure, a non-adhesive corrugated packaging box, boasts a simple structure, ingenious design, and rational layout. It addresses the problems of traditional corrugated packaging box structures, where various components are formed by gluing together multiple corrugated cardboard sheets, resulting in a large workload and poor flexibility. A unique structure is designed to address these issues. It uses a top plate and connecting limiting blocks to assemble a limiting frame on the bottom plate that matches the battery's outline. Pads are placed within the limiting frame to support the battery. While providing stable support and restricting the battery's freedom of movement, the top plate does not require pre-gluing. Instead, multiple top plate pieces are threaded and fixed into a single structure using T-shaped pins. This effectively reduces the processing steps for the top plate, saving production time and costs. Furthermore, this easy-to-assemble and disassemble structure allows users to adjust it according to actual needs; simply replacing the top plate with a different size allows for the construction of a new limiting frame, enhancing its adaptability. Moreover, its simple manufacturing process and low production cost make it a highly advantageous and widely applicable solution in this field, with a promising market prospect.
