Detailed Implementation
[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Considering the large size and open design on all four sides, the product's compressive strength is significantly compromised, especially the balance of pressure. Therefore, multi-layer corrugated cardboard must be used. Furthermore, since nearly 85% of the four sides are open, the load-bearing structure needs to be reinforced through multiple folds to enhance overall compressive strength. The corrugated cardboard box can only be formed by direct folding. With the top 100% open and the left and right sides 85% open, we must use top-to-bottom and left-to-right folds to divide and maintain the integrity of each cardboard side. All folded cardboard sections are positioned and shaped using interlocking and mutual restraint methods. A four-sided open display box folding structure includes a front panel 1, side panels 2 connected to the left and right ends of the front panel 1, a back panel 3 connected to the other end of each side panel 2, a bottom insert 6 connected to the bottom of the front panel 1, and bottom insert inner folding pieces 5 connected to the bottom of each of the two side panels 2. The lower end of the back panel 3 is connected to the bottom female piece 4. The bottom female piece 4, the bottom side inner folding piece 5, and the bottom male piece 6 constitute the bottom. The upper ends of the two side panels 2 are respectively provided with two corner fixing connecting pieces 7 for connecting the front panel 1 and the back panel 3. Although the design structure is relatively complex, it is still necessary to ensure that all structures can be directly completed in one go through die-cutting. Each part of the device is completed in one go through die-cutting. The connecting parts are also borrowed in accurate and reasonable positions, which does not affect the functional requirements of the entire product and ensures that the function of the borrowed area is not damaged.
[0023] The display box is open on the top, two sides, and the front, with all four sides being openwork. The display box is made of corrugated cardboard, which is die-cut in one piece. The main folding structure of the display box is composed of 2-3 layers of corrugated cardboard for reinforcement, giving it extremely high compressive strength and stability. There are corner fixing connecting pieces 7 at the four corners of the top opening. The corner fixing connecting pieces 7 are integral pieces, and the ends of the corner fixing connecting pieces 7 are also provided with two layers of cardboard tongues 71. The tongues 71 are also provided with reinforced inner tongues 72.
[0024] Please see Figure 1 , Figure 2 and Figure 3 The front panel 1 is provided with a front side ear fixing plate 10, and the upper end of the front side ear fixing plate 10 is connected to a front inner folding plate 101. The upper end of the front panel 1 is connected to a front inner closed inner folding frame 8, and the front lip inner folding plate 9 is connected to the front panel 1. The front inner closed inner folding frame 8 and the front lip inner folding plate 9 are folded backward to increase the pressure bearing capacity of the front panel 1. The side panel 2 is respectively connected with a side inner folding frame 11, a side lip inner folding plate 12, and a side fixed inner folding plate 13. The side inner folding frame 11, the side lip inner folding plate 12, and the side fixed inner folding plate 13 are folded backward and fixedly connected to the side panel 2 to increase the pressure bearing capacity of the side panel 2.
[0025] Please see Figure 1 , Figure 2 and Figure 3 The back panel 3 has a bottom female piece 4 connected to its lower side. The bottom female piece 4, the bottom side inner folding piece 5, and the bottom male piece 6 are inserted together to form the bottom of the display box, which is used to support the items placed on the device. The back panel 3 has a back inner folding plate 14 connected to its upper side. The back inner folding plate 14 is folded and fixedly connected to the back panel 3, increasing the thickness of the back panel 3 and thus improving its pressure-bearing capacity. The front inner closed inner folding frame 8 and the back inner folding plate 14 are respectively provided with insertion holes 15 for connecting corner fixing connecting pieces 7. The corner fixing connecting piece 7 is provided with a tongue 71, and the upper end of the tongue 71 is provided with a reinforced inner tongue 72. A locking tongue 73 is provided at the lower end of the tongue 72. By inserting the tongue 71 into the insertion hole 15 and reinforcing it with the inner tongue 72, the connection is ensured to be firm, giving it extremely high pressure resistance and stability, and making it easy to stack. Insertion holes 15 are provided on the folding openings of the front panel 1 and the back panel 3 respectively, corresponding to the position of the tongue 71. Two insertion ports are provided at the connection between the bottom male piece 6 and the front panel 1. Two insertion ports are provided at the connection between the side panel 2 and the bottom side inner fold piece 5. The insertion ports are used to fix the inner fold plate 9 of the front lip and the inner fold plate 12 of the side lip, preventing the inner fold plate 9 of the front lip and the inner fold plate 12 of the side lip from not fitting with the front panel 1 and the side panel 2.
