Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically to a multi-piece transport packaging carton. 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., and they come in various specifications and models.

[0003] Cardboard boxes commonly use three-layer or five-layer paper, while seven-layer paper is less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while corrugated paper is used for the core paper. The colors and textures of different types of paper vary, and different manufacturers also produce different types of paper.

[0004] However, existing cardboard boxes typically use mesh-like baffles to separate the internal space, but the space cannot be adjusted, resulting in a relatively fixed space that cannot accommodate items of different sizes. At the same time, the cardboard boxes lack cushioning measures, and when subjected to bumps and jolting, the force generated by the bumps may cause the bottom of the packaging cardboard box to make hard contact with the contact surface of the transport vehicle, resulting in damage to the items inside the packaging cardboard box. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A multi-piece transport packaging carton includes a bottom frame, a protective mechanism inside the bottom frame, a packaging box mounted on the upper end of the protective mechanism, a support mechanism inside the packaging box, and symmetrically arranged locking rails on both inner walls of the packaging box, with locking blocks slidably embedded inside the locking rails.

[0007] The protective mechanism includes a base plate, the lower end of which is fixedly installed to the bottom of the inner cavity of the base frame. Limiting grooves are provided on both inner walls of the base frame. Telescopic rods are symmetrically fixed at the four corners of the upper end of the base plate. Springs are sleeved on the outside of the telescopic rods. A support plate is fixedly installed on the top of the telescopic rods. Limiting blocks are symmetrically fixedly connected to both ends of the support plate.

[0008] Preferably, the limiting block matches the limiting groove and is slidably installed, and the support plate is slidably connected to the inside of the bottom frame.

[0009] Preferably, the two ends of the spring are fixedly connected to the opposite surfaces of the base plate and the support plate, respectively.

[0010] Preferably, the support mechanism includes a support frame, the two ends of the support frame are fixedly connected to the bottom end of the locking block, end frames are symmetrically fixed on both sides of the support frame, side frames are fixedly installed on the inner side of the end frames, a partition plate is slidably installed on the outer side of the support frame, a screw sleeve is fixedly installed on the top of the partition plate, and a fastening bolt is installed on the internal thread of the screw sleeve.

[0011] Preferably, the support frame, end frame, and side frame can form a rectangular frame, and the frame fits snugly against the interior of the bottom frame.

[0012] Preferably, the lower end of the fastening bolt is connected to the upper end of the partition plate and is movably installed.

[0013] Preferably, the lower end of the packaging box is fixedly connected to the upper end of the support plate.

[0014] Preferably, both the rail and the block are "T" shaped.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model provides a multi-piece transport packaging carton. Through a protective mechanism, when the carton is subjected to force and bumps during transportation, the carton can drive the support plate to move downward within the bottom frame, thereby compressing the telescopic rod and spring. The elasticity of the spring and telescopic rod can buffer and protect the carton, preventing the bottom of the carton from directly and hardly colliding with the contact surface of the transport vehicle caused by the force generated by the bumps. In this way, by improving the compression resistance and shock absorption effect of the carton, the goods are better protected.

[0017] This utility model provides a multi-piece transport packaging carton. Through a support mechanism, a rectangular frame can be formed by a support frame, end frame, and side frame. The frame can be placed inside the packaging box to fit the box body, thereby improving the support strength of the packaging carton. When using the packaging carton, it can avoid damage or deformation of the packaging carton, thus preventing waste. Furthermore, the partition plate can slide on the support frame, thereby allowing the space after partitioning to be adjusted according to items of different sizes, improving the flexibility of the packaging carton.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-5 As shown, this utility model provides a multi-piece transport packaging carton, including a bottom frame 1, a protective mechanism 2 inside the bottom frame 1, a packaging box 3 installed at the upper end of the protective mechanism 2, a support mechanism 4 inside the packaging box 3, and symmetrically provided locking rails 5 on both inner walls of the packaging box 3, with locking blocks 6 slidably embedded inside the locking rails 5.

[0026] The lower end of the packaging box 3 is fixedly connected to the upper end of the support plate 23.

[0027] Both the track 5 and the block 6 are T-shaped.

[0028] In this design, the support frame 41, end frame 42 and side frame 43 are easily disassembled and assembled by the movable insertion between the rails 5.

[0029] like Figures 3-4 As shown, the protection mechanism 2 includes a base plate 21. The lower end of the base plate 21 is fixedly installed to the bottom of the inner cavity of the base frame 1. Limiting grooves 22 are opened on both sides of the inner wall of the base frame 1. Telescopic rods 25 are symmetrically fixed at the four corners of the upper end of the base plate 21. Springs 26 are sleeved on the outside of the telescopic rods 25. A support plate 23 is fixedly installed on the top of the telescopic rods 25. Limiting blocks 24 are symmetrically fixedly connected to both ends of the support plate 23.

[0030] The limiting block 24 matches the limiting groove 22 and is slidably installed, and the support plate 23 is slidably connected to the inside of the bottom frame 1.

[0031] The two ends of the spring 26 are fixedly connected to the opposite surfaces of the base plate 21 and the support plate 23, respectively.

[0032] In this design, when the support plate 23 slides up and down, it will drive the limiting block 24 to slide synchronously in the limiting groove 22, so as to limit the support plate 23 and make its movement smooth.

[0033] In this solution, the protective structure prevents the bottom of the packaging carton from directly colliding with the contact surface of the transport vehicle. In traditional transportation methods, such direct contact often results in severe damage to the bottom of the packaging carton, which in turn affects the safety of the contents. The protective structure greatly improves the compression resistance and cushioning effect of the packaging carton. It can continuously provide stable cushioning protection for the packaging carton during transportation, keeping the contents in a relatively stable environment and further protecting them from damage caused by bumps.

[0034] like Figure 5 As shown, the support mechanism 4 includes a support frame 41. The two ends of the support frame 41 are fixedly connected to the bottom end of the locking block 6. End frames 42 are symmetrically fixed on both sides of the support frame 41. Side frames 43 are fixedly installed on the inner side of the end frames 42. A partition plate 44 is slidably installed on the outer side of the support frame 41. A screw sleeve 45 is fixedly installed on the top of the partition plate 44. A fastening bolt 46 is installed in the internal thread of the screw sleeve 45.

[0035] The support frame 41, end frame 42, and side frame 43 can form a rectangular frame, and the frame fits into the interior of the bottom frame 1.

[0036] The lower end of the fastening bolt 46 is connected to the upper end of the partition plate 44 and is movably installed.

[0037] In this solution, the position of the partition 44 can be freely changed according to the actual size of the packaged items through the supporting structure, thereby making precise adjustments to the separated space. This flexible space adjustment function enables the packaging carton to show greater flexibility when facing diverse packaging needs and fully meet the packaging requirements of different items.

[0038] The working principle of this multi-piece transport packaging carton will be explained in detail below.

[0039] like Figures 1-5As shown, when using this multi-piece transport packaging carton, the support frame 41, end frame 42, and side frame 43 can first be combined to form a rectangular frame, which is then precisely placed inside the packaging box 3. This ensures that the frame fits tightly against the inner walls of the box, significantly improving the overall support strength of the packaging carton. This prevents it from being easily damaged or deformed even when squeezed during use, providing excellent protection for the contents. Subsequently, the space within the box can be adjusted as needed. By loosening the fastening bolts 46, the partition plate 44 can slide on the support frame 41, allowing for adjustments to the space after partitioning according to the size of the items. After adjustment, tighten the fastening bolts 46 to fix the partition plate 44. Finally, the items can be placed in the appropriate partition space. When the packaging carton containing the items encounters bumps during transportation, the packaging box 3 will be subjected to a downward impact force in an instant. At this time, the packaging box 3 will drive the support plate 23 to move downward quickly within the bottom frame 1. As the support plate 23 moves downward, it will directly act on the telescopic rod 25 and the spring 26, squeezing them. The elastic effect of the spring 26 can offset the impact force, thus protecting the packaging box 3 and better protecting the items inside.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
