[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 - Figure 4 As shown, an adjustable steel structure connection device mainly includes core components such as steel structure A1, steel structure B2, electromagnetic controller 5 and electromagnetic plate 6. Steel structure A1 and steel structure B2 are set to be placed perpendicular to each other to provide a stable connection foundation.

[0024] On the tube body of the steel structure A1, a fastening sleeve A3 and a fastening sleeve B4 are cleverly sleeved. Electromagnetic plates 6 are provided on one side of the inner wall of the two fastening sleeves. An electromagnetic controller 5 is also installed on the fastening sleeve B4, which is responsible for controlling the power-on state of the two electromagnetic plates 6. When the electromagnetic plates 6 are powered on, they will be adsorbed on the steel structure A1 to fix the fastening sleeves.

[0025] The steel structure B2 is provided with a U-shaped cover A7 and a U-shaped cover B8. A protrusion 12 is provided at the connection of the two U-shaped covers, and a limit rod 13 is inserted between the two opposite protrusions 12. The two ends of the limit rod 13 are fixed by limit nuts 14 to ensure the relative position between the U-shaped cover A7 and the U-shaped cover B8 is stable. In addition, the U-shaped cover A7 and the U-shaped cover B8 are also connected with fastening screws 9, which pass through the sleeves of the fastening sleeve A3 or the fastening sleeve B4 to further fix the steel structure.

[0026] The rod head of the fastening screw 9 is provided with a tightening block 10 and an anti-skid pad 11. When the fastening screw 9 is tightened, the tightening block 10 and the anti-skid pad 11 will press tightly against the steel structure A1 to ensure the precise alignment between the steel structure A1 and the steel structure B2. When the screw holes of the two steel structures are aligned, fasteners are used to connect them to achieve a stable steel structure connection.

[0027] In addition, the inner hole widths of the fastening sleeves A3 and B4 are consistent with the width of the steel structure A1, ensuring the tightness and stability of the sleeve. The electromagnetic plate 6 is fixed to the fastening sleeve by bolts, and its wires pass through the openings of the fastening sleeve to connect with the electromagnetic controller 5, which facilitates the power supply and control of the electromagnetic plate 6.

[0028] The structures of U-shaped covers A7 and B8 are exactly the same, and their inner hole widths are consistent with the width of steel structure B2, ensuring that the steel structure can be smoothly inserted. The cross-sections of the two U-shaped covers are designed in a "U" shape, which is not only convenient for installation, but also provides good support and stability. The fastening screw 9 is threadedly connected to the U-shaped cover, making the fastening operation easier and more reliable.

[0029] The pressing block 10 and the fastening screw 9 are fixed by bolts, while the pressing block 10 and the anti-skid pad 11 are connected by bonding, which not only ensures the firmness of the connection but also prevents loosening or falling off during use.

[0030] The protrusion 12 and the U-shaped cover A7 or the U-shaped cover B8 are designed as one body, which enhances the integrity and stability of the structure. Rubber gaskets are also provided on the two opposite protrusions 12 to increase the sealing and shock absorption effect of the connection.

[0031] The two ends of the limit rod 13 are provided with threads to facilitate the connection with the limit nut 14. The middle part of the rod body is smooth to reduce friction and wear. The limit nut 14 is connected to the thread of the limit rod 13 by threading to fix the relative position of the U-shaped cover to ensure the stability and reliability of the connection.

[0032] The adjustable steel structure connection device is ingeniously designed, stable in structure, and easy to operate. It is suitable for various steel structure occasions that require flexible adjustment and stable connection. Through reasonable structural design and component configuration, it achieves precise alignment and stable connection between steel structures, providing a strong guarantee for the safety and stability of steel structures.

[0033] During operation: First, according to actual needs, select appropriate steel structure A1 and steel structure B2. Make sure that the two steel structures are placed vertically to provide a stable connection foundation. Then, put the fastening sleeve A3 and the fastening sleeve B4 on the steel structure A1, and pay attention to keeping the fastening sleeve in the appropriate position; control the power-on state of the electromagnetic plate 6 through the electromagnetic controller 5. When the electromagnetic plates 6 are energized, they will be adsorbed on the steel structure A1 to fix the fastening sleeve. This step ensures the stable position of the fastening sleeve on the steel structure and provides a basis for subsequent connection operations; put the U-shaped cover A7 and the U-shaped cover B8 on the steel structure B2. Make sure that the connection between the two U-shaped covers is aligned, and insert the limit rod 13 between the protrusions 12. Then, use the limit nut 14 to fix the two ends of the limit rod 13 to ensure the relative position between the U-shaped cover A7 and the U-shaped cover B8 is stable. This step provides stable support for subsequent tightening operations; use the tightening screw 9 to pass through the sleeve of the tightening sleeve A3 or the tightening sleeve B4, and tighten it until the tightening block 10 and the anti-skid pad 11 are tightly against the steel structure A1. This step ensures the precise alignment and stable connection between the steel structure A1 and the steel structure B2; when the screw holes of the two steel structures are aligned, fasteners are used to connect them to achieve a stable steel structure connection. At this point, the entire connection device has completed its work task, providing a strong guarantee for the safety and stability of the steel structure.
