Description

Technical Field

[0001] This invention relates to the field of container technology, and in particular to a lightweight container beam-column structure. Background Technology

[0002] A shipping container is a large cargo container with standardized dimensions and a robust seal. It is usually made of steel and enables efficient and standardized cargo transportation. Whether between cargo ships, trains, or trucks, it can be quickly transferred without repeated loading and unloading of the cargo itself, which greatly reduces transportation time and labor costs. At the same time, the sealed structure can effectively protect the cargo from damage caused by wind, rain, and collisions, which greatly promotes the scale and convenience of cross-border trade.

[0003] Currently, commercially available shipping containers mainly consist of a frame, metal panels, and doors. In use, the metal panels are installed on the frame, and cargo is loaded and unloaded through the doors. However, because the metal panels and frame are primarily connected by welding, the welded joints bear significant stress concentrations under lifting and stacking loads. Under cyclic loads, cracks easily develop and propagate over time, reducing the container's lifespan. To address this, existing technologies add reinforcing ribs or plates around the welded joints to improve structural strength and extend the container's lifespan. However, in practical use, the large weight of steel containers means a significant portion of energy is consumed during transport, rather than on the cargo itself. This directly increases the unit cost of transporting cargo and carbon emissions. Furthermore, the weight of the steel walls hinders quick installation and disassembly, reducing the device's practicality and failing to meet user needs. Summary of the Invention

[0004] The purpose of this invention is to provide a lightweight container beam-column structure, which solves the problem that existing container beam-column structures are heavy and inconvenient to install.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A lightweight container beam-column structure includes two steel plates. First side plates are provided at the front and rear ends of adjacent sides of the two steel plates. Second side plates are provided at the left and right ends of adjacent sides of the two steel plates. Fixing mechanisms are provided at the left and right ends of the front sides of the interior of the two steel plates to facilitate container assembly. Protective mechanisms are provided around the outer perimeter of the two steel plates to prevent damage to the container. A disassembly mechanism is provided at the top of the upper steel plate to facilitate the lifting of larger items. The fixing mechanism includes multiple sliding grooves, which are respectively opened on the left and right ends of adjacent sides of the two steel plates. The upper and lower sides of the two second side plates are slidably connected to the corresponding sliding grooves. The left and right ends of the front sides of the interior of the two sliding grooves are provided with mounting slots. A stop block is provided on one side of the interior of each mounting slot. One side of the stop block penetrates through the steel plate. A pushing block is provided in the middle of the interior of the mounting slot. One side of the pushing block contacts the stop block.

A reset component is provided inside the mounting slot.

[0006] By using the above technical solution, which employs two layers of steel plates and installs a first side plate and a second side plate between the two layers of steel plates, the container can be assembled more conveniently, reducing the automation of the device, improving its practicality, and meeting the needs of users.

[0010] Through the above technical solution, the rotation of the bidirectional threaded rod will drive the slider to move, and push the movable plate to move through the connecting rod, so that the locking block is disengaged from the locking slot, thereby disassembling the top plate. This enables the hoisting of larger items, facilitating the disassembly and loading of larger items and improving the convenience of the device.

[0011] Preferably, the reset assembly includes a plurality of second guide rods, which are respectively fixedly connected to one side of the corresponding mounting groove. A second spring is provided on the outer side of the second guide rod, one end of the second spring is fixedly connected to the connecting piece, and one end of the second guide rod passes through the corresponding connecting piece and the push block in sequence. A first guide rod is fixedly connected to the other side of the mounting groove, and a first spring is slidably connected to the outer side of the first guide rod. One end of the first spring is fixedly connected to the stop block.

[0012] Through the above technical solution, the second spring pulls the push block through the connecting piece, and pushes the stop block downward through the first spring, so that the stop block is inserted into the groove and the second side plate is fixed.

[0013] Preferably, the control component includes a driven bevel gear, a plurality of driven bevel gears are respectively fixedly connected to one end of a corresponding threaded column, a rotating rod is rotatably connected to the upper and lower ends of one side of a plurality of protective rods, one end of a plurality of rotating rods passes through a corresponding protective rod and is fixedly connected to a driving bevel gear, and the plurality of driving bevel gears are respectively meshed with the corresponding driven bevel gears.

[0014] Through the above technical solution, rotating the rotating rod will drive the active bevel gear to rotate, and through the meshing transmission between the active bevel gear and the driven bevel gear, the threaded column will be driven to rotate.

[0015] Preferably, the disassembly mechanism further includes two knobs, which are respectively fixedly connected to the right end of the corresponding bidirectional threaded rod, and the size of the slider matches the inner size of the square groove.

[0016] With the above technical solution, workers can easily rotate the bidirectional threaded rod using a knob, and the slider is limited by the square groove.

[0017] Preferably, the fixing mechanism includes a box door, and two box doors are respectively rotatably connected to the front and rear ends of the right wall of the second side plate on the right side. Hinges are fixedly connected to the upper and lower sides of the opposite end of the right wall of the two box doors, and the two box doors are respectively rotatably connected to the second side plate through corresponding hinges.

[0018] With the above technical solution, loading and unloading of goods can be carried out more conveniently by opening the container door.

[0019] Preferably, the upper steel plate has fixing blocks fixedly connected to the front and rear ends of both sides, and each of the fixing blocks has a lifting hole on its top.

[0020] The above technical solution allows workers to easily lift containers, thus facilitating their movement.

[0023] Preferably, positioning clips are fixedly connected to the top four corners of the upper steel plate, and positioning blocks are fixedly connected to the bottom four corners of the lower steel plate.

[0024] Through the above technical solution, when containers are stacked, the interaction between the positioning card and the positioning block can make the stacking of containers more orderly.

[0025] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention inserts two first side plates between two steel plates on both sides, and moves a rubber block. The rubber block moves a pushing block through a connecting piece, thereby squeezing the stop block and retracting it into the inside of the steel plate. This allows the second side plate to be inserted into the sliding groove, thus fixing the second side plate. This facilitates the assembly of containers. Furthermore, by using steel plates on both sides, the amount of steel used is reduced, thereby reducing the weight and improving the practicality of the device, which can meet the needs of users.

[0026] 2. This invention fixes the protective rod at the corner of the steel plate by placing the protective rod on the corner and rotating the rod. The rotating rod is driven by the meshing of the active bevel gear and the driven bevel gear, which drives the threaded column to rotate. This causes the L-shaped blocks on both sides to slide inside the groove and finally lock into the groove, thus fixing the protective rod at the corner of the steel plate. The protective rod can greatly improve the mechanical strength of the container and prevent damage to the container from collisions, thereby improving the safety of the container.

[0027] 3. This invention rotates a bidirectional threaded rod, thereby moving a slider. The slider, through a connecting rod, moves a movable plate, causing the locking block to disengage from the slot, thus removing the top plate. This allows for the hoisting of larger items and improves the convenience of the device. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 The present invention will be further described in detail below.

[0031] This invention provides a lightweight container beam-column structure, which includes two steel plates 1. The front and rear ends of the two adjacent sides of the two steel plates 1 are provided with first side plates 5, and the left and right ends of the adjacent sides of the two steel plates 1 are provided with second side plates 6. The left and right ends of the front sides of the two steel plates 1 are provided with fixing mechanisms 2, which are used to facilitate the assembly of the container. The outer sides of the two steel plates 1 are provided with protective mechanisms 3, which are used to prevent damage to the container. The top of the upper steel plate 1 is provided with a disassembly mechanism 4, which is used to facilitate the lifting of larger items. The fixing mechanism 2 includes multiple sliding grooves 21, which are respectively opened on the left and right ends of adjacent sides of two steel plates 1. The upper and lower sides of two second side plates 6 are slidably connected to the corresponding sliding grooves 21, and the second side plates 6 can be installed inside the sliding grooves 21. The left and right ends of the front side of the interior of each of the two sliding grooves 21 are provided with mounting grooves 22. A stop block 25 is provided on one side of the interior of each mounting groove 22. One side of the stop block 25 penetrates through the steel plate 1 and can be inserted into the sliding groove 21 to fix the second side plate 6. A pushing block 26 is provided in the middle of the interior of the mounting groove 22. One side of the pushing block 26 contacts the stop block 25 and can push the stop block 25 to move. A connecting piece 27 is fixedly connected to the other side of the pushing block 26. The front end of the connecting piece 27 penetrates through the steel plate 1 and is fixedly connected to a rubber block 28. Moving the rubber block 28 can drive the pushing block 26 to move through the connecting piece 27. The unit is equipped with a reset assembly 29, which includes multiple second guide rods 291. The multiple second guide rods 291 are fixedly connected to one side of the corresponding mounting groove 22. A second spring 292 is provided on the outside of the second guide rod 291. One end of the second guide rod 291 passes through the corresponding connecting piece 27 and the pushing block 26 in sequence. The second spring 292 will pull the pushing block 26 to move. A first guide rod 23 is fixedly connected to the other side of the mounting groove 22. A first spring 24 is slidably connected to the outside of the first guide rod 23. One end of the first spring 24 is fixedly connected to the stop block 25. The first spring 24 can push the stop block 25 into the slide groove 21. The fixing mechanism 2 also includes a guide rail 210. Multiple guide rails 210 are fixedly connected to the front and rear ends of the adjacent sides of the two steel plates 1. The upper and lower sides of the two first side plates 5 are slidably connected to the corresponding guide rails 210. The guide rails 210 can provide guidance for the first side plates 5. Specifically, when assembling the container, the two first side plates 5 are first inserted between the two steel plates 1, and the rubber block 28 is moved. The rubber block 28 is connected to the push block 26 through the connecting piece 27. Therefore, when the rubber block 28 is moved, it can drive the push block 26 to move. Since the contact surface between the push block 26 and the stop block 25 is designed with an inclined surface, when the push block 26 moves, it will squeeze the stop block 25, causing the stop block 25 to retract from the slide groove 21 and into the inside of the steel plate 1. Then, the second side plate 6 is inserted into the inside of the slide groove 21. At this time, the container is released. When the rubber block 28 is opened, the second spring 292 pulls the push block 26 through the connecting piece 27, causing it to retract. At the same time, the first spring 24 pushes the stop block 25 downward and re-inserts it into the slide groove 21, thereby fixing the second side plate 6. This not only enables the container to be installed quickly, but also the container adopts a structure of two side steel plates 1, a first side plate 5 and a second side plate 6, which can greatly reduce the amount of steel used while ensuring strength, thereby effectively reducing the weight of the container and improving the practicality of the device, which can meet the needs of users.

[0032] The protective mechanism 3 includes multiple protective rods 31, which are respectively located at the four corners on the outer sides of the two steel plates 1. Each protective rod 31 has an inner cavity 37 on its upper and lower sides. Support blocks 32 are fixedly connected to the left and right sides of each inner cavity 37. Threaded posts 33 are rotatably connected to the inner sides of each support block 32. L-shaped blocks 34 are threadedly connected to the outer sides of each threaded post 33. When the threaded posts 33 move, the L-shaped blocks 34 move accordingly. Multiple grooves 35 are formed on the outer sides of the two steel plates 1. One end of each L-shaped block 34 passes through a corresponding protective rod 31 and engages with a groove 35. When the L-shaped blocks 34 move, they engage with the grooves. The slot 35 engages, and control components 36 are provided on the inner sides of multiple inner cavities 37. The control components 36 include driven bevel gears 361. Multiple driven bevel gears 361 are fixedly connected to one end of the corresponding threaded column 33. Rotating rods 362 are rotatably connected to the upper and lower ends of one side of multiple protective rods 31. One end of multiple rotating rods 362 passes through the corresponding protective rod 31 and is fixedly connected to an active bevel gear 363. The rotating rods 362 will drive the active bevel gears 363 to rotate. Multiple active bevel gears 363 are respectively meshed with the corresponding driven bevel gears 361. When the active bevel gears 363 rotate, the driven bevel gears 361 will drive the threaded column 33 to rotate. Specifically, after the container is installed, the protective rod 31 is placed on the corner of the steel plate 1, and the rotating rod 362 is rotated. The rotating rod 362 will drive the driving bevel gear 363 to start rotating. Since the driven bevel gear 361 meshes with the driving bevel gear 363, when the driving bevel gear 363 rotates, the driven bevel gear 361 will also be driven to start rotating. The rotation of the driven bevel gear 361 will further drive the threaded column 33 to rotate. During the rotation of the threaded column 33, it will drive the L-shaped block 34 connected to it to move. As the L-shaped blocks 34 on both sides move, they will eventually engage with the groove 35, ensuring that the protective rod 31 is firmly fixed. The protective rod 31 can effectively prevent the container from being damaged when it encounters a collision during transportation and improve the overall physical strength of the container, thereby ensuring the safe transportation of goods and improving the safety of the container.

[0033] The disassembly mechanism 4 includes two square slots 41, which are respectively formed inside the upper steel plate 1 at the front and rear ends. One side of each square slot 41 is rotatably connected to a double-threaded rod 42. The right ends of both double-threaded rods 42 penetrate the upper steel plate 1. Slider blocks 43 are threadedly connected to the left and right sides of the outer walls of both double-threaded rods 42. When the double-threaded rods 42 rotate, the sliders 43 move accordingly. One side of each slider 43 is rotatably connected to a connecting rod 44. The other side of each square slot 41 is slidably connected to a movable plate 45. One end of each connecting rod 44 is rotatably connected to a corresponding movable plate 45. When the sliders 43 move, the connecting rods 44 can push the movable plate 45. 5. The two movable plates 45 are fixedly connected to the left and right ends of adjacent sides with locking blocks 46. The upper steel plate 1 is provided with a top plate 47. The top, front and rear ends, left and right sides of the top of the top plate 47 are provided with locking slots 48. Multiple locking blocks 46 are engaged with the corresponding locking slots 48. The movable plate 45 will drive the locking blocks 46 to move, so that they are disengaged from the locking slots 48. The disassembly mechanism 4 also includes two knobs 49. The two knobs 49 are fixedly connected to the right end of the corresponding bidirectional threaded rod 42. The knobs 49 make it convenient for the operator to rotate the bidirectional threaded rod 42. The size of the slider 43 matches the size of the inner side of the square groove 41, so that the slider 43 can move with the bidirectional threaded rod 42 when it rotates. Specifically, when lifting large objects inside the container, rotating the double-threaded rods 42 on both sides will push the slider 43 to move. During the movement of the slider 43, the connecting rod 44 connected to it will drive the movable plate 45 to move. The movement of the movable plate 45 will further drive the locking block 46 to move, so that the locking block 46 will disengage from the locking slot 48, thereby conveniently removing the top plate 47. This provides sufficient space and convenient conditions for lifting large items and improves the convenience of the device.

[0034] The fixing mechanism 2 includes a container door 211. The two container doors 211 are rotatably connected to the front and rear ends of the right wall of the second side plate 6 on the right side. The upper and lower sides of the right wall of the two container doors 211 are fixedly connected to each other. The two container doors 211 are rotatably connected to the second side plate 6 through the corresponding hinges 212. The front and rear ends of the left and right sides of the upper steel plate 1 are fixedly connected to fixing blocks 7. The top of the multiple fixing blocks 7 is provided with lifting holes 8, which can be used to easily lift the container. Specifically, the hinge 212 allows for easy opening of the container door 211, facilitating the loading and unloading of goods. The lifting hole 8 allows for easier lifting of the container, making it easier for staff to move the container.

[0035] Positioning clips 9 are fixedly connected to the top four corners of the upper steel plate 1, and positioning blocks 10 are fixedly connected to the bottom four corners of the lower steel plate 1. The positioning blocks 10 can make the containers stack more neatly. Specifically, the positioning card 9 and the positioning block 10 can provide positioning when containers are stacked, making container stacking more convenient.

[0036] Working principle: When the container needs to be assembled, first insert the two first side plates 5 between the two steel plates 1 on both sides, and then move the rubber block 28. The rubber block 28 can drive the push block 26 to move through the connecting piece 27. Due to the inclined design of the contact surface between the stop block 25 and the push block 26, the push block 26 will squeeze the stop block 25 when it moves, and retract the stop block 25 from the slide 21 and let it into the inside of the steel plate 1. Then, insert the second side plate 6 into the slide 21. At this time, release the rubber block 28. The second spring 292 will pull the push block 26 through the connecting piece 27 to make it retract. And through the first spring 24, push the stop block 25 downward to insert into the slide 21, thereby fixing the second side plate 6. This can quickly install the container. Moreover, the container uses two steel plates 1, first side plates 5 and second side plates 6, which can greatly reduce the amount of steel used, thereby reducing the weight. After the container is installed, the protective rod 31 is placed on the corner of the steel plate 1, and the rotating rod 362 is rotated. The rotating rod 362 will drive the driving bevel gear 363 to rotate. Since the driven bevel gear 361 meshes with the driving bevel gear 363, when the driving bevel gear 363 rotates, the driven bevel gear 361 will drive the threaded column 33 to rotate. When the threaded column 33 rotates, it can drive the L-shaped block 34 to move. Through the movement of the L-shaped blocks 34 on both sides, the L-shaped blocks 34 on both sides can be firmly engaged with the groove 35, thereby fixing the protective rod 31. The protective rod 31 prevents the container from being damaged in the event of a collision and improves the physical strength of the container. Finally, when it is necessary to lift a large object inside the container, rotate the double-threaded rods 42 on both sides. When the double-threaded rods 42 rotate, they will push the slider 43 to move. When the slider 43 moves, it will drive the movable plate 45 to move through the connecting rod 44. The movable plate 45 will further drive the locking block 46 to move, so that the locking block 46 will disengage from the locking slot 48, and the top plate 47 can be easily removed, which can lift larger items.
