Description

Technical Field

[0001] The utility model relates to the technical field of heavy-duty cartons, in particular to a split combined heavy-duty carton. Background Art

[0002] Heavy-duty cartons are a type of carton that is more resistant to paper and has a stronger pressure-bearing capacity than ordinary cartons. They are usually used to wrap goods or items to protect the outer layer. The size of the carton varies depending on the size of the goods. Due to the use of thicker cardboard and reinforced structural design, the combined heavy-duty cartons have a higher carrying capacity and can withstand the weight of heavier items. As an indispensable part of modern logistics, heavy-duty cartons bear important responsibilities such as containers, product protection and aesthetics.

[0003] Heavy cartons are usually fixed with screws, which can provide high strength and stability. By screwing the screws into the object, two or more parts can be firmly connected to prevent them from loosening or moving. At the same time, screw fixing is relatively easy to install and remove. Only the appropriate tools (such as screwdrivers or wrenches) are needed to complete the fixing or release, which makes maintenance, replacement or adjustment more convenient.

[0004] However, screw fastening requires pre-processing holes in the objects to be connected so that the screws can pass through and fix. This requires additional processing steps and tools, which increases the complexity and time cost of the work. Screw fastening may be problematic when connecting thin sheet materials. Thin sheet materials may not be suitable for screw fastening because the screws need to pass through the material and need to be thick enough to provide a strong connection. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a split combined heavy-duty carton, which aims to improve the problem that the existing heavy-duty carton is fixed with screws, resulting in complicated fixing steps.

[0007] Furthermore, the sliding assembly includes a partition and a slide groove, the slide groove is opened on the inner wall of the side plate, and the outer wall of the partition is slidably connected to the inside of the slide groove.

[0008] Furthermore, both sides of the interior of the partition are rotatably connected with a second rotating shaft, and one side of the outer wall of the second rotating shaft is fixedly connected with a worm gear.

[0009] Furthermore, worms are rotatably connected on both sides of the partition, and the worms are meshed with the worm wheels.

[0010] Furthermore, one end of the worm is fixedly connected to a second driving block, and an outer wall of the second driving block is rotatably connected to the interior of the partition.

[0011] Furthermore, a rotating rod 1 is fixedly connected to one side of the outer wall of the second rotating shaft, and a clamping block 2 is slidably connected inside the partition.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a split combined heavy-duty carton, including a bottom plate 3, a side plate 1 is slidably connected inside the bottom plate 3, a rectangular array of fixed columns 4 are fixedly connected inside the bottom plate 3, a rectangular array of slots 5 are opened inside the side plate 1, the outer wall of the fixed column 4 is slidably connected inside the slot 5, a rotating shaft 8 is rotatably connected inside the slot 5, a driving block 7 is fixedly connected to the top of the rotating shaft 8, a plurality of positive and negative threaded rods 10 are fixedly connected to the outer wall of the rotating shaft 8, both sides of the outer wall of the positive and negative threaded rods 10 are threadedly connected with movable blocks 11, the outer wall of the movable block 11 is rotatably connected with a transmission rod 9 of a ring array, one side of the transmission rod 9 is rotatably connected with a card block 12, the outer wall of the card block 12 is slidably connected inside the slot 5, and the outer wall of the card block 12 is slidably connected inside the side plate 1;

[0025] Specifically, first, place the side panel 1 on the top of the bottom panel 3. In order to ensure a firm connection between the side panel 1 and the bottom panel 3, a fixing column 4 is designed on the top of the bottom panel 3. These fixing columns 4 not only play a supporting role, but more importantly, they can be inserted into the slots 5 inside the side panel 1, providing additional fixing force for the side panel 1. Next, we drive the rotating shaft 8 to rotate through the driving block 7. The rotation of the rotating shaft 8 not only drives the rotation of the positive and negative screw rods 10, but also with the rotation of the positive and negative screw rods 10, the symmetrical movable blocks 11 begin to move toward the center. In this process, the movable block 11 pushes the card block 12 out of the slot 5 through the transmission rod 9, and accurately inserts it into the side panel 1, thereby realizing the assembly of the side panel 1 and the bottom panel 3.

[0026] Reference Figure 2 and Figure 4 A sliding assembly is arranged inside the side plate 1, and the sliding assembly includes a partition plate 2 and a slide groove 6. The slide groove 6 is opened on the inner wall of the side plate 1, and the outer wall of the partition plate 2 is slidably connected to the inside of the slide groove 6. The inside of the partition plate 2 is rotatably connected with a rotating shaft 2 16 on both sides, and a worm gear 15 is fixedly connected to one side of the outer wall of the rotating shaft 2 16. A worm 14 is rotatably connected to both sides of the inside of the partition plate 2, and the worm 14 is meshed with the worm gear 15. One end of the worm 14 is fixedly connected to a driving block 2 13, and the outer wall of the driving block 2 13 is rotatably connected to the inside of the partition plate 2, and a rotating rod 1 17 is fixedly connected to one side of the outer wall of the rotating shaft 2 16. A card block 2 19 is slidably connected to the inside of the partition plate 2, and a rotating rod 2 18 is rotatably connected to both sides of the rotating rod 17. One side of the rotating rod 2 18 is rotatably connected to one side of the card block 2 19, and the outer wall of the card block 2 19 is slidably connected to the inside of the side plate 1;

[0027] Specifically, first, the partition 2 can be inserted through the slide groove 6 inside the side plate 1, and then the worm 14 is driven to rotate through the driving block 2 13, and its rotation can drive the worm wheel 15 to rotate. As the worm wheel 15 rotates, the rotating shaft 2 16 will also rotate accordingly. One end of the rotating rod 17 is connected to the rotating shaft 2 16, and the other end is connected to the block 2 19 through the rotating rod 2 18. When the rotating rod 17 starts to rotate, it will push the block 2 19 to move through the rotating rod 2 18. When the block 2 19 is pushed, it will slide out of the partition 2 and be inserted into the side plate 1, thereby realizing the firm fixation of the partition 2 inside the side plate 1.

[0028] Working principle: When assembling the carton, the side panel 1 can be placed on the top of the bottom panel 3, and the fixing column 4 on the top of the bottom panel 3 is inserted into the slot 5 inside the side panel 1. Then, the driving block 7 can be used to drive the rotating shaft 8 to rotate, and then the rotating shaft 8 drives the positive and negative screw rods 10 to rotate. With the rotation of the positive and negative screw rods 10, the symmetrical movable blocks 11 can be driven to move toward the center, so that the movable blocks 11 can push the card block 12 out of the slot 5 through the transmission rod 9 and insert it into the side panel 1, so that the side panel 1 can be assembled. The plate 1 is assembled and fixed with the bottom plate 3. When the partition 2 is installed, the partition 2 can be inserted into the side plate 1 through the slide groove 6 inside the side plate 1, and then the worm 14 is driven to rotate through the driving block 2 13, and the worm 14 drives the worm wheel 15 to rotate, and the rotating shaft 2 16 rotates with the worm wheel 15, thereby driving the rotating rod 1 17 to rotate, and then the rotating rod 1 17 pushes the clamping block 2 19 through the rotating rod 2 18, so that the clamping block 2 19 slides out of the partition 2 and is inserted into the side plate 1, so that the partition 2 is fixed inside the side plate 1.
