[0020] like Figures 1 to 7As shown, a safe and stable welded steel pipe includes a cylindrical steel pipe main structure 1. The main structure 1 has a central mating hole 2. The front of the central mating hole 2 has a steel pipe forming groove 4 that completely penetrates the entire structure from left to right, forming the main structure of the welded steel pipe. A combined limiting mating groove 3 is located on the left front of the main structure 1, allowing for precise positioning and mating with components spliced at the ends during later use, ensuring easier connection during installation. The middle of the steel pipe forming groove 4 has staggered locking grooves 5 distributed vertically along the entire length. The width of the inner side of each locking groove 5 is greater than the width of the side closest to the steel pipe forming groove 4. The main structure of the steel pipe main structure 1 has an integrally formed locking boss 6 located inside the locking groove 5, forming a locking and anti-detachment structure. This prevents excessive deformation or damage to the steel pipe body from internal mating components during use, resulting in better overall structural strength of the steel pipe. The locking boss 6 has a fastening connection hole 7 that completely penetrates the inner and outer sides of the entire structure, allowing for the fastening connection of internally assembled products with fastening bolts. The right side of the main steel pipe structure 1 has circumferentially distributed welding positioning grooves 8, enabling precise welding during end connections, ensuring better connection strength and higher processing accuracy. By setting staggered locking structures at the seams of the seamed steel pipe, it prevents excessive deformation during use, enhancing the overall structural durability and safety. The positioning grooves and welding grooves at both ends ensure greater ease of installation, higher assembly accuracy, easier welding, better welding stability, higher overall weld strength, and higher processing efficiency during welding.
[0021] Preferably, the locking groove 5 is composed of an arc-shaped structure and a triangular structure, which makes the locking structure more stable and the overall locking strength higher during use.
[0022] Preferably, the inner side of the welding positioning groove 8 is an inclined slope structure, which improves the smoothness of welding, provides a larger welding space at the welding position, further enhances the welding strength, and improves the safety of the fit during later use.
[0023] Preferably, the dimensions of the slots 5 are all the same, which makes the overall structure more convenient to manufacture and process, and also improves the structural stability.
[0024] Preferably, the two ends of the combined limiting groove 3 are respectively provided with splicing and welding stabilizing grooves. The inner side of the splicing and welding stabilizing groove is an inclined slope structure, which can provide a precise fit for the welding position when the splicing position is connected, making the welding operation more convenient and the fit strength of the connection position higher.
[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
