DETAILED DESCRIPTION

[0026] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0027] Please refer to Figures 1 to 4In a preferred embodiment, the new lining of the present invention mainly includes a first support member 1 and a second support member 2, wherein the first support member 1 includes a first bottom plate 11 and a first side plate 12, and the first side plate 12 is formed by bending the two ends of the first bottom plate 11. The second support member 2 includes a second bottom plate 21 and a second side plate 22, and the second side plate 22 is formed by bending the two ends of the second bottom plate 21. The first side plate 12 is provided with two first plug-in slots 13, and an insertion portion 14 is formed between the two first plug-in slots 13. The second bottom plate 21 is provided with an assembly slot 23, and the two ends of the assembly slot 23 respectively extend to the two second side plates 22 to form a second plug-in slot 24. The second plug-in slot 24 is connected to the first plug-in slot 13 one by one, and the insertion portion 14 extends from the assembly slot 23 into between the two second side plates 22 to form an accommodating space.

[0028] Exemplarily, both the first support member 1 and the second support member 2 can be made of existing cardboard such as single-corrugated cardboard, double-corrugated cardboard, triple-corrugated cardboard, and hardboard. Of course, plastic boards can also be used. The first side panels 12 are located at both ends of the first base plate 11, and the two first side panels 12 are vertically opposite to each other. The second side panels 22 are located at both ends of the second base plate 21, and the two second base plates 21 are vertically opposite to each other. The first side panels 12 and the second side panels 22 extend in two mutually perpendicular directions respectively. Each first side panel 12 is provided with two first plug-in slots 13, and the two first plug-in slots 13 extend vertically from the upper end of the first side panel 12 to the middle of the first side panel 12. Each second side panel 22 is provided with two second plug-in slots 24, and the two second plug-in slots 24 extend vertically from the lower end of the second side panel 22 to the middle of the second side panel 22. The second base plate 21 is provided with two assembly slots 23, and the assembly slots 23 extend horizontally to both ends of the second base plate 21 and are connected to the two opposite second plug-in slots 24.

[0029] It can be seen from the above technical solution that by bending the first support member 1 and the second support member 2 respectively, two generally "concave"-shaped structures are formed, and the first plug-in slot 13 and the second plug-in slot 24 are respectively provided on the two. Through the mutual cooperation between the first plug-in slot 13, the second plug-in slot 24, and the assembly slot 23, the second support member 2 can be arranged between the two first side panels 12 of the first support member 1 by plugging, and the insertion portion 14 and the second side panel 22 are enclosed to form a space for placing products. The assembly process does not require gluing, the overall structure is ingenious, the operation is simple, and it can be achieved with only two pieces of cardboard. It is easy to process and has low manufacturing cost.

[0030] Please refer to Figure 2In this embodiment, the height of the second side panel 22 is less than that of the first side panel 12, forming a gap 3 between the first bottom panel 11 and the second bottom panel 21. Setting the height of the second side panel 22 smaller than that of the first side panel 12 ensures that the second side panel 22 can be fully inserted into the first side panel 12, thus ensuring connection strength. Furthermore, the gap 3 between the first bottom panel 11 and the second bottom panel 21 creates a buffer space beneath the product, further protecting it.

[0031] The two ends of the first support member 1 protrude from the second side panel 22 to form a first buffering ridge 15, and the two ends of the second support member 2 protrude from the first side panel 12 to form a second buffering ridge 25. The first buffering ridge 15 and the second buffering ridge 25 extend outward from the second side panel 22 and the first side panel 12, respectively, thereby forming a buffer space around the periphery of the liner to prevent the second side panel 22 from directly contacting or colliding with the outside and causing damage to the product.

[0032] The upper end of the first side panel 12 is flush with the upper end of the second side panel 22 , which can ensure that the packaging box is flatter after the liner is placed in the packaging box, thereby ensuring the stability of the overall structure.

[0033] In this embodiment, the width of the first insertion slot 13 matches the thickness of the second side panel 22, and the width of the second insertion slot 24 matches the thickness of the first side panel 12. The widths of the first insertion slot 13 and the second insertion slot 24 match the thicknesses of the second side panel 22 and the first side panel 12, respectively, ensuring a tight fit between the first support member 1 and the second support member 2, thereby enhancing the overall structural strength.

[0034] In this embodiment, the distance between the two first plug-in slots 13 is equal to the distance between the two second side panels 22, and the distance between the two second plug-in slots 24 is equal to the distance between the two first side panels 12, thereby ensuring that the first plug-in slot 13 is smoothly docked with the second plug-in slot 24. By adjusting the positions of the first plug-in slot 13, the second plug-in slot 24, and the assembly slot 23, the lining can be made suitable for products of different sizes, and has a wide range of applications.

[0035] The utility model also provides a packaging box, comprising a box body and at least one of the above-mentioned novel linings, wherein the novel lining is arranged in the box body.
