[0001] This utility model relates to a cardboard box, specifically a recyclable, high-strength, wear-resistant cardboard box. Background Technology
[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc. Commonly used cardboard boxes have three or five layers, with each layer consisting of linerboard, corrugated paper, core paper, and face paper.
[0003] However, existing cardboard boxes usually do not have any protective structure on the outside, which causes the box itself to rub directly against external objects or the ground when it is moved and handled, and it is easy to wear out over time. Utility Model Content
[0004] The purpose of this utility model is to provide a reusable, high-strength, wear-resistant cardboard box. By having an outer lining mesh and an outer frame in contact with external objects, the strength and wear resistance of the box are improved, allowing the box to be reused and extending its lifespan.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a recyclable, high-strength, wear-resistant cardboard box, comprising a box body, the box body being a cavity structure with an opening at one end and a hollow interior, and an inner lining structure provided within the cavity of the box body, the inner lining structure including an inner back panel, the inner back panel being attached to the bottom of the box body cavity, and each of the four corners of the inner back panel having through holes penetrating both ends therethrough, the four through holes penetrating both ends of the box body, and each of the four through holes having a stepped groove on its upper end face; an outer lining structure provided below the box body, the outer lining structure including an outer frame and an outer lining mesh plate fixed to the inner side of the outer frame, multiple cylinders fixed to the upper end face of the outer frame, upper support shafts rotatably connected to the upper end faces of the multiple cylinders, and positioning bars fixed to the multiple upper support shafts, the upper support shafts and positioning bars being provided within the cavity of the box body.
[0006] Preferably, four cover plates are fixedly connected to the top of the box, and the opening of the box cavity is closed by the cooperation of the four cover plates.
[0007] Preferably, the inner lining back panel has a U-shaped design, with fixing straps on all four sides. The four fixing straps pass through the inner and outer sides of the box, and the two ends of the fixing straps are tightly fitted to the box and the inner lining back panel, respectively.
[0008] Preferably, perforated slots are provided on all four sides of the outer frame, and four fixing straps pass through the four perforated slots respectively.
[0009] Preferably, the outer frame is fitted to the lower end face of the box.
[0010] Preferably, there are four cylinders in total, and the four cylinders pass through the four through holes respectively.
[0011] Preferably, the cylinder and the upper support shaft are designed to be non-coaxial.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the setting of the outer lining structure, makes the box body not need to directly contact the ground. Therefore, when moving or transporting the box body, the box body will not directly rub against external objects. Instead, the outer lining mesh plate and the outer frame contact external objects, thereby improving the strength and wear resistance of the box body, enabling the box body to be reused and extending its service life.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0024] Please see Figure 1 One embodiment of this utility model is a recyclable high-strength wear-resistant cardboard box, including a box body 1. The box body 1 is a cavity structure with an opening at one end and a hollow interior. Four cover plates 2 are fixedly connected to the top of the box body 1. The opening of the cavity of the box body 1 can be closed by the cooperation of the four cover plates 2.
[0025] Please see Figure 2 The cavity of the box 1 is provided with an inner lining structure 3, which includes an inner lining back plate 31. The inner lining back plate 31 is attached to the bottom of the cavity of the box 1. The inner lining back plate 31 is designed in the shape of a square, and a fixing strap 32 is provided on all four sides of the inner lining back plate 31.
[0026] Please see Figure 3The inner back panel 31 has through holes at each of its four corners, all penetrating both ends of the box body 1. Each of the four through holes has a stepped groove 33 on its upper surface. An outer lining structure 4 is located below the box body 1. The outer lining structure 4 includes multiple cylinders 43, each with an upper support shaft 44 rotatably connected to its upper surface. Positioning rods 45 are fixed to each upper support shaft 44. Both the upper support shafts 44 and the positioning rods 45 are located within the cavity of the box body 1. The cylinders 43 and the upper support shafts 44 are non-coaxial, allowing the upper support shafts 44 to rotate the positioning rods 45 and position them within the cavity. Figure 3 The state shown in the figure allows the positioning bar 45 to abut against the inner wall of the stepped groove 33, thereby fixing the cylinder 43 in the stepped groove 33. This allows the outer frame 41 and the outer lining mesh plate 42 to be integrated with the inner lining back plate 31, ensuring that the outer frame 41 and the outer lining mesh plate 42 can perform their functions.
[0027] Please see Figure 4 All four fixing straps 32 pass through the inner and outer sides of the box 1, and the two ends of the fixing straps 32 are tightly attached to the box 1 and the inner lining back panel 31 respectively, so that the four fixing straps 32 can fix the inner lining back panel 31.
[0028] Please see Figure 5 The outer frame 41 is attached to the lower end face of the box 1. There are four cylinders 43, and the four cylinders 43 pass through the four through holes respectively.
[0029] Please see Figure 6 The outer lining structure 4 also includes an outer frame 41 and an outer lining mesh plate 42 fixed inside the outer frame 41, and multiple cylinders 43 are fixed to the upper end face of the outer frame 41.
[0030] Please see Figure 7 The outer frame 41 has perforated slots 411 on all four sides, and the four fixing straps 32 pass through the four perforated slots 411 respectively, so that the four fixing straps 32 can be installed smoothly.
[0031] Please refer to the following: Figures 1 to 7 In use, the inner backing plate 31 is first placed at the bottom of the cavity of the box 1, and then the box 1 is placed on top of the outer frame 41, so that the four cylinders 43 are respectively inserted into the four through holes, allowing the four upper support shafts 44 and the four positioning bars 45 to enter the four stepped grooves 33 respectively. Then, the operator rotates the four positioning bars 45 to move them to the attached position. Figure 3In the state shown, the four positioning bars 45 can abut against the inner lining back plate 31 in the four stepped grooves 33 respectively, so that the outer frame 41 and the inner lining back plate 31 are integrated into one, ensuring that the outer lining structure 4 is fixed to the bottom of the box 1, so that the outer frame 41 and the outer lining mesh plate 42 directly rub against external objects, and the box 1 will not generate friction, thus ensuring the high strength and wear resistance of the box 1.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
