Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box fixing technology, specifically, to a practical combined packaging box body that prevents products from being bumped, scratched, and deformed. Background Technology
[0002] With the explosive growth of high-end manufacturing industries such as new energy vehicles and semiconductors, and driven by both environmental policies and intelligent technologies, packaging boxes with customized structures, high-performance materials, intelligent monitoring, and green recyclability will become the mainstream in the market. Ordinary wooden packaging boxes on the market are mostly assembled from wooden boards without internal securing devices, offering no protection for the appearance or shape of machined products, often resulting in defects or deformation of the product during transportation.
[0003] Since the packaging box is assembled from wooden boards and has no internal fastening device, it provides no protection for the appearance or shape of the machined products. During transportation, the products are easily damaged by external impacts, causing them to shake and move. Therefore, a practical modular packaging box is proposed to prevent the products from being scratched and deformed. Utility Model Content
[0004] The purpose of this utility model is to provide a practical combined packaging box to prevent products from being scratched and deformed, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides a practical combination packaging box to prevent product scratches and deformation. The box includes a main body with a reinforcing frame fixedly connected to its outer side. A fixing component is installed inside the main body, comprising a double-ended screw. Threaded grooves are provided at both ends of the double-ended screw, and hexagonal nuts are threaded to both ends of the double-ended screw. By rotating the hexagonal nuts near the top of the double-ended screw, the goods inside the packaging box are secured.
[0006] As a further improvement to this technical solution, multiple support bars are fixedly connected to the bottom side of the main body of the packaging box, and the multiple support bars are fixedly connected to the reinforcing frame. One of the support bars located in the middle of the bottom side of the main body of the packaging box has a hexagonal groove in the middle of its bottom side. One of the hexagonal nuts is slidably connected to the hexagonal groove, and the hexagonal groove is used to limit the position of the hexagonal nut.
[0007] As a further improvement to this technical solution, a sealing cover is provided on the top side of the main body of the packaging box and the reinforcing frame. The reinforcing frame is fixedly connected to the top side of the sealing cover. A limiting hole is opened at the center of the bottom side of the sealing cover, and the limiting hole extends to the reinforcing frame.
[0008] As a further improvement to this technical solution, the bottom end of the double-ended screw penetrates through the main body of the packaging box and one of the support bars. At the same time, the double-ended screw is rotatably connected to the main body of the packaging box and one of the support bars, and the bottom end of the support bar extends into the hexagonal groove.
[0009] As a further improvement to this technical solution, the top end of the double-ended screw is located inside the limiting hole, which is used to limit the double-ended screw.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] In practical modular packaging boxes designed to prevent product scratches and deformation, the lack of internal fixing components in existing boxes can lead to goods being squeezed and deformed or damaged during transportation. By using a double-ended screw in the fixing component, the goods inside the main body of the packaging box can be limited, and two hexagonal nuts can be used to secure the goods within the main body of the packaging box. This solves the problem of goods moving within the main body of the packaging box and causing deformation or damage. Attached Figure Description

[0019] Please see Figures 1-3 As shown, this embodiment provides a practical combination packaging box to prevent product scratches and deformation. It includes a main body 1, with a reinforcing frame 2 fixedly connected to the outer side of the main body 1. The reinforcing frame 2 strengthens the main body 1, preventing damage during transportation. A fixing component 3 is installed inside the main body 1 to secure the goods inside, preventing deformation or damage during transport. The fixing component 3 includes a double-ended screw 31, with threaded grooves at both ends on the outer side of the double-ended screw 31. Hexagonal nuts 32 are threadedly connected to both ends of the double-ended screw 31. The two threaded grooves on the double-ended screw 31 facilitate the connection of the two hexagonal nuts 32. The connection is achieved by rotating the screw. The hexagonal nut 32 near the top of the double-ended screw 31 secures the goods in the main body 1 of the packaging box, preventing the goods from moving inside the main body 1. Multiple support bars 4 are fixedly connected to the bottom side of the main body 1, and these support bars 4 are also fixedly connected to the reinforcing frame 2. The multiple support bars 4 provide support for the main body 1 of the packaging box and the reinforcing frame 2. One of the support bars 4 located in the middle of the bottom side of the main body 1 has a hexagonal groove 5 in the middle of its bottom side. One hexagonal nut 32 is slidably connected to the hexagonal groove 5, and the hexagonal groove 5 is used to limit the hexagonal nut 32. The bottom end of the double-ended screw 31 passes through the main body 1 of the packaging box and one of the support bars 4, and the double-ended screw 31 is rotatably connected to the main body 1 of the packaging box and one of the support bars 4. At the same time, the bottom end of the support bar 4 extends into the hexagonal groove 5.
[0020] Please see Figures 1-2As shown, a sealing cover 6 is provided on the top side of the main body 1 of the packaging box and the reinforcing frame 2. A reinforcing frame 7 is fixedly connected to the top side of the sealing cover 6. The sealing cover 6 and the reinforcing frame 7 can seal the main body 1 of the packaging box. A limiting hole 8 is provided at the center of the bottom side of the sealing cover 6, and the limiting hole 8 extends to the reinforcing frame 7. The top end of the double-ended screw 31 is located in the limiting hole 8. The limiting hole 8 is used to limit the double-ended screw 31 and at the same time strengthen the fixation of the double-ended screw 31 to the goods.
[0021] In this embodiment, the practical combination packaging box for preventing product scratches and deformation is used as follows: First, remove one of the hexagonal nuts 32 from the outside. Align the fixing hole on the goods with the double-ended screw 31. Then, insert the goods into the main body 1 of the packaging box along the double-ended screw 31. Secure the goods with one of the hexagonal nuts 32. Finally, align the limiting hole 8 with the top of the double-ended screw 31 and place the sealing cap 6 on the top side of the main body 1 and the reinforcing frame 2 to seal the box.
