Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a built-in support and reinforcement device for packaging boxes. Background Technology

[0002] In modern commerce, the production, transportation, and sales of goods are closely linked, and packaging boxes, as the "protective shell" of goods, play an indispensable role. From the moment a product rolls off the production line in the factory, to its storage in the warehouse, and then through long-distance transportation to reach the retail terminal, and finally to being presented to the consumer, goods face various complex environments and external forces throughout the entire circulation process.

[0003] Most existing packaging boxes rely solely on the strength of their own materials to withstand external forces. While ordinary paper packaging boxes are low in cost, their strength is limited. Some packaging boxes made of cardboard or plastic, although improving their strength to some extent, still cannot provide sufficient protection when faced with significant external forces. To enhance the pressure resistance of packaging boxes, some merchants add auxiliary measures such as wrapping tape and packing straps to the outside of the packaging boxes. However, these methods have limited effectiveness, are cumbersome to operate, and may also damage the appearance of the packaging boxes, thereby reducing their practicality. Utility Model Content

This device can solve the problem that most packaging boxes rely solely on the strength of their own materials to resist external forces. Although ordinary paper packaging boxes are low in cost, their strength is limited. Some packaging boxes made of cardboard or plastic materials have improved their strength to a certain extent, but they still cannot provide sufficient protection when faced with large external forces. In order to enhance the pressure resistance of packaging boxes, some merchants will add auxiliary measures such as wrapping tape and packing straps to the outside of the packaging boxes. However, these methods have limited effectiveness, are cumbersome to operate, and may also damage the appearance of the packaging boxes, thereby reducing the practicality of the packaging boxes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a built-in support and reinforcement device for a packaging box, comprising a packaging box and a box lid, wherein the packaging box is provided with support and reinforcement components;

[0006] The support and reinforcement assembly includes a first support rod, a second support rod, two connecting rods, and two support placement rods. The two support placement rods are placed on both sides inside the lower end of the packaging box. The upper surface of the second support rod has a groove, and the lower surface of the first support rod has the same groove. The outer walls at both ends of the two support placement rods have second T-shaped block grooves.

[0007] The outer walls of the protrusions at both ends of the two support rods are provided with conical block grooves. A base plate is placed inside the packaging box. Four first T-shaped block grooves are provided on the inner wall of the packaging box. Four first T-shaped blocks are fixedly connected to the lower outer wall of the box cover. Four corner reinforcement blocks are provided inside the packaging box. The lower outer wall of the box cover is slidably connected to the inner wall of the packaging box.

[0008] Preferably, one outer wall of each of the two supporting rods is fitted to the inner walls of both sides of the packaging box, and the four second T-shaped block slots are in groups of two.

[0009] The outer walls of the T-shaped blocks at both ends of the two connecting rods are slidably connected to the interior of the corresponding second T-shaped block groove.

[0010] Preferably, the four conical block slots are arranged in pairs, and the outer walls of the conical blocks at both ends of the second support rod are slidably connected to the interior of the corresponding conical block slots.

[0011] The outer walls of the conical blocks at both ends of the first support rod are slidably connected to the interior of the corresponding conical block grooves.

[0012] Preferably, the groove on the first support rod and the groove on the second support rod are used in conjunction, and one outer wall of the two connecting rods is in contact with the inner wall of the packaging box.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a built-in support and reinforcement device for a packaging box, including a packaging box 1 and a box lid 2;

[0031] The packaging box 1 is equipped with support and reinforcement components;

[0032] The support and reinforcement assembly includes a first support rod 8, a second support rod 11, two connecting rods 12, and two support placement rods 13. The two support placement rods 13 are placed on both sides of the lower end of the packaging box 1. The upper surface of the second support rod 11 has a groove 7. One side of the outer wall of the two support placement rods 13 corresponds to the inner walls of both sides of the packaging box 1. The lower surface of the first support rod 8 has the same groove 7. The outer walls of both ends of the two support placement rods 13 have second T-shaped block grooves 10. The four second T-shaped block grooves 10 are grouped in pairs. The outer walls of the T-shaped blocks at both ends of the two connecting rods 12 are slidably connected to the interior of the corresponding second T-shaped block grooves 10. The outer walls of the protrusions at both ends of the two support placement rods 13 have conical block grooves 9. The four conical block grooves 9 are grouped in pairs. The outer walls of the conical blocks at both ends of the second support rod 11 are slidably connected to the interior of the corresponding conical block grooves 9. The outer walls of the conical blocks at both ends of the first support rod 8 are slidably connected to the interior of the corresponding conical block grooves 9. The groove 7 on the first support rod 8 and the groove 7 on the second support rod 11 are slidably connected to the interior of the second support rod 11. The slots 7 are used in conjunction, with one outer wall of each of the two connecting rods 12 correspondingly fitting against the inner wall of the packaging box 1. A base plate 5 is placed inside the packaging box 1, with its four outer sides correspondingly fitting against the four inner sides of the packaging box 1. The upper surfaces of the two support rods 13 are in contact with the lower surface of the base plate 5, and the upper surfaces of the two connecting rods 12 are in contact with the lower surface of the base plate 5. Four first T-shaped block slots 3 are provided on the inner wall of the packaging box 1, and four first T-shaped blocks 4 are fixedly connected to the lower outer wall of the box cover 2. The interior of the packaging box 1 is equipped with… Four corner reinforcement blocks 6 are L-shaped. The lower outer wall of the box cover 2 is slidably connected to the inner wall of the packaging box 1. The outer walls of the T-shaped blocks on the four corner reinforcement blocks 6 are slidably connected to the interior of the corresponding first T-shaped block groove 3. The outer walls of the four first T-shaped blocks 4 are slidably connected to the interior of the corresponding first T-shaped block groove 3. The upper surface of the T-shaped blocks on the four corner reinforcement blocks 6 is in contact with the lower surface of the corresponding first T-shaped block 4. The lower outer walls of the four corner reinforcement blocks 6 are in contact with the upper surface of the base plate 5.

[0033] Furthermore, when using this device, firstly, place the two support rods 13 inside the lower end of the packaging box 1 on both sides, ensuring that one outer wall of each rod is tightly fitted against the inner walls of both sides of the packaging box 1. Align the T-shaped blocks at both ends of the two connecting rods 12 with the second T-shaped block slots 10 at both ends of the support rods 13 and insert them into them, sliding them into place to complete the connection between the connecting rods 12 and the support rods 13. At this time, one outer wall of each connecting rod 12 is also fitted against the inner wall of the packaging box 1. Next, align the conical blocks at both ends of the first support rod 8 and the second support rod 11 with the outer protrusions at both ends of the support rods 13. The conical block groove 9 of the wall is inserted and slidably connected, so that the first support rod 8 and the second support rod 11 are mounted on the support placement rod 13, and the groove 7 on the first support rod 8 and the groove 7 on the second support rod 11 cooperate with each other to form a stable lateral support structure. Then, the base plate 5 is placed inside the packaging box 1, so that its four outer walls are in contact with the four inner walls of the packaging box 1, and at the same time, the lower surface of the base plate 5 contacts the upper surface of the support placement rod 13 and the connecting rod 12, completing the installation of the support and reinforcement assembly inside the packaging box 1. Then, the T-shaped blocks of the four corner reinforcement blocks 6 are respectively aligned with the first corner reinforcement blocks 6 on the inner wall of the packaging box 1. A T-shaped slot 3 is inserted and slidably connected to fix the corner reinforcement block 6 at the four corners of the packaging box 1. Finally, the four first T-shaped blocks 4 at the bottom of the box lid 2 are aligned with the first T-shaped slot 3 on the inner wall of the packaging box 1, inserted and slidably connected. At this time, the outer wall at the bottom of the box lid 2 is slidably connected to the inner wall of the packaging box 1, and the upper surface of the T-shaped block on the four corner reinforcement blocks 6 is in contact with the lower surface of the corresponding first T-shaped block 4, completing the assembly of the entire packaging box. In this way, when the packaging box 1 is subjected to external pressure, the pressure from above is first transmitted to the box lid 2, and the box lid 2 disperses the pressure through the four first T-shaped blocks 4. The corner reinforcement blocks 6 are arranged in an "L" shape, which can effectively enhance the pressure resistance of the corners of the packaging box 1 and prevent corner deformation. The bottom plate 5 transfers the weight of the internal items to the support placement rod 13 and connecting rod 12 below. The frame structure formed by the support placement rod 13 and connecting rod 12, as well as the lateral support structure formed by the first support rod 8 and the second support rod 11, jointly bear and distribute the pressure, enhance the internal support strength of the packaging box 1, prevent the packaging box 1 from deforming in the vertical and horizontal directions, and provide a stable protective space for the internal items.

[0034] When the packaging box 1 is subjected to external pressure, the lid 2 distributes the pressure to the four corner reinforcement blocks 6 through the four first T-shaped blocks 4, which can effectively enhance the pressure resistance of the corners of the packaging box 1 and prevent corner deformation. Then, the bottom plate 5 transfers the weight of the internal items to the support placement rod 13 and connecting rod 12 below. The frame structure composed of the support placement rod 13 and connecting rod 12 jointly bears and distributes the pressure, enhances the internal support strength of the packaging box 1, prevents the packaging box 1 from deforming in the vertical and horizontal directions, and provides a stable protective space for the internal items.
