[0002] With the rapid development of building construction, stage construction, and outdoor support scaffolding, steel pipes, as crucial components for temporary support and connection structures, directly impact the safety of the entire structural system through their convenience and stability. To meet the demands for rapid assembly and high-strength support in various scenarios, the market is constantly seeing the emergence of various improved steel pipe connection devices, striving to enhance their operational efficiency and stability during the assembly and connection process.

[0003] In existing technologies, steel pipe connections typically rely on methods such as insertion, welding, threaded tightening, or clamping for structural splicing. These structural principles are mostly based on friction locking or rigid nesting, with the combination of two steel pipe sections achieved through manual docking or positioning with auxiliary tools. To increase stability, some devices also incorporate mechanical structures such as limit pins, clamps, or reinforcing sleeves between the steel pipes. However, these connection methods often require cumbersome alignment, large operating space, or specific tools, affecting the connection efficiency during temporary assembly and potentially leading to loosening or misalignment during frequent disassembly and reassembly.

[0004] However, the following problems still exist in the existing technology: the combination connection method between steel pipes is usually simple in structure. Due to the limitations of clamping force and locking structure strength, the connection is prone to loosening or separation after being subjected to external impact or vibration, which affects the overall stability and safety of the structure and limits the scope of use and long-term performance of steel pipes in complex construction environments.

The fixing component is used to realize the mechanical locking between the steel pipes, thereby enhancing the stability and safety of the overall connection.

[0034] The fixing assembly includes a clamping plate 5, which is the main external fixing structure. Its inner wall fits against the outer wall of the first steel pipe 1 and the second steel pipe 2, forming a ring-shaped support to improve the tensile and shear resistance of the connection. A buckle 6 is fixedly connected to the outer wall of the clamping plate 5. The buckle 6 is used to cooperate with the subsequent hook 10 to achieve quick overlap and locking of the clamping plate structure. A clamping plate 7 is provided on one side of the clamping plate 5. The clamping plate 7 is a component that cooperates with the clamping plate 5 to form a symmetrical clamping structure, which helps to enhance the clamping effect. Hooks 10 are fixedly connected to both sides of the clamping plate 7. The hooks 10 can engage with the buckles 6 to form a stable mechanical interlocking structure, preventing the clamping plate from slipping during use. A wing bolt 8 is threaded inside the clamping plate 7. The wing bolt 8 serves as a manual fastening component, which can be rotated to tighten the clamping structure, facilitating... For quick installation and disassembly, one end of the wing bolt 8 is rotatably connected to a clamping plate 11. The clamping plate 11 enhances the stability of the clamping structure. Its inner wall is in contact with the outer wall of the first steel pipe 1 and the second steel pipe 2, further dispersing stress and preventing displacement. The inner wall of the clamping plate 11 is in contact with the outer wall of the first steel pipe 1 and the second steel pipe 2. One end of the wing bolt 8 is provided with a limiting component. The limiting component is used to prevent the wing bolt 8 from rotating out of position, protecting the structural safety and facilitating standardized installation. The limiting component includes a limiting plate 9. One side of the limiting plate 9 is fixedly connected to one end of the wing bolt 8. The clamping plate 11 is rotatably connected to a limiting groove 12. The limiting groove 12 is used to accommodate the limiting plate 9, so that it forms a locked state after rotating into position. The limiting plate 9 is rotatably connected inside the limiting groove 12, thereby limiting the rotation range of the wing bolt 8 during clamping, ensuring stable structural locking and convenient operation.

[0035] Reference Figure 4 and Figure 5The first steel pipe 1 has a slot 13 inside, which is used to limit the engagement of the connecting column 15, thereby enhancing the overall stability between the steel pipe and the chassis 14. The connecting column 15 is slidably connected inside the first steel pipe 1. The connecting column 15 is used to move up and down inside the first steel pipe 1 to achieve connection with the chassis 14 and height adjustment. The chassis 14 is fixedly connected to the bottom of the connecting column 15. The chassis 14 serves as a supporting foundation structure and is used to contact the ground to improve the stability and load-bearing capacity of the overall support device. A locking block 16 is rotatably connected inside the connecting column 15. The locking block 16 is used to achieve mechanical engagement with the slot 13, thereby effectively preventing the connecting column 15 from shifting or falling off during use. The locking block 16 and the slot 13 engage precisely to achieve a reliable locking function. A support rod 17 is rotatably connected to one side of the locking block 16. The support rod 17 is used to connect the locking block 16 and the limiting structure to form a force transmission support structure, improving the stability of the connection system. One end of the support rod 17 is rotatably connected to a limit plate 18. Position plate 2 18, as a sliding limiting device, can restrict the range of motion of support rod 17, enhance the stress balance of the internal structure of connecting column 15, and limit plate 2 18 is slidably connected inside connecting column 15. This sliding connection helps to release and buffer the internal stress of the device, and improves the structural stability. A telescopic rod 19 is provided inside connecting column 15. The telescopic rod 19 is used to provide a variable stroke support path for limit plate 2 18 to adapt to the extension and contraction requirements under different connection states. A spring 20 is sleeved on the outer wall of telescopic rod 19. The spring 20 is used to provide rebound force to ensure that limit plate 2 18 can automatically reset under non-stressed state. One end of telescopic rod 19 and spring 20 are fixedly connected to the bottom of limit plate 2 18. Through the integrated connection with limit plate 2 18, the elastic element and the structural limiting work together. The other end of telescopic rod 19 and spring 20 are fixedly connected inside connecting column 15 to ensure the stability of spring 20 and telescopic rod 19 inside the structure, avoid displacement or loosening during operation, and improve the overall stress support effect.

[0036] Working principle: When using this support type steel pipe, firstly, when connecting the first steel pipe 1 and the second steel pipe 2, the second steel pipe 2 is inserted into the outer wall of the guide post 3 through the guide groove 4. Then, the clamp 1 5 is sleeved at the connection between the second steel pipe 2 and the first steel pipe 1. Then, the clamp 2 7 is embedded into the buckle 6 through the hook 10. Then, the wing bolt 8 is rotated to drive the clamp 3 11 to adhere to the outer wall of the first steel pipe 1 and the second steel pipe 2, so that the clamp 3 11 is tightly attached to the outer wall of the first steel pipe 1 and the second steel pipe 2. Then, the first steel pipe 1 and the second steel pipe 2 are fixed by the clamp 3 11 and the clamp 1 5. The wing bolt 8 is limited in the limiting groove 12 by the limiting plate 1 9, which achieves the effect of facilitating the connection of the combined steel pipes.

[0037] When the base plate 14 is installed at the bottom of the first steel pipe 1, the base plate 14 is inserted into the first steel pipe 1 through the connecting column 15. Then, the locking block 16 in the connecting column 15 is engaged with the slot 13 to lock the connecting column 15. One side of the locking block 16 is connected to the connecting column 15, and the other side of the locking block 16 is connected to the limiting plate 18 through the support rod 17 and limited in the connecting column 15. It is supported by the tension of the spring 20, so that the locking block 16 can be stably engaged in the slot 13, thereby increasing the force-bearing area of ​​the steel pipe.
