Description

Technical Field

[0001] This utility model relates to the field of steel pipe galvanizing technology, specifically to a galvanized pipe that is easy to splice. Background Technology

[0002] Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanized and electro-galvanized types. Electro-galvanized pipe has lower cost, but its surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipe. Galvanized steel pipe is widely used in construction, machinery, fire protection, power, and highways.

[0003] In practical applications, galvanized pipes often need to be spliced ​​according to specific length requirements. However, traditional welding splicing not only requires specialized equipment and technicians, but is also cumbersome and inefficient. Furthermore, the galvanized layer at the weld joint is easily damaged by high temperatures, leading to a decrease in local corrosion resistance. Flange connections require additional flanges, bolts, and other accessories, increasing material costs and installation complexity. Moreover, the overall structure after splicing is bulky, making it unsuitable for space-constrained scenarios. While some simple socketing methods are easy to operate, they suffer from poor connection stability, are prone to loosening, and have insufficient sealing at the splice joint, making it easy for media leaks (such as liquids and gases) to occur, affecting the safety and reliability of use. Therefore, we propose a galvanized pipe that is easy to splice to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a galvanized pipe that is easy to splice, thus solving the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a galvanized pipe that is easy to splice, including a galvanized pipe one and a galvanized pipe two, wherein the top end of the galvanized pipe one is spliced ​​with the galvanized pipe two, and a splicing structure is provided between the galvanized pipe one and the galvanized pipe two.

[0006] The splicing structure includes a movable tube, which is sleeved on the top outer wall of galvanized pipe one and can slide along the axial direction of galvanized pipe one. A sealing ring one is fixedly installed at the bottom end of the movable tube. A threaded groove is opened at the top end of the inner wall of the movable tube. The movable tube is threadedly connected to external threaded pipe one and external threaded pipe two from bottom to top through the threaded groove. External threaded pipe one is fixedly connected to the top outer wall of galvanized pipe one. External threaded pipe two is fixedly connected to the bottom outer wall of galvanized pipe two. A sealing ring two is fixedly installed at the top end of external threaded pipe two on the outer wall of galvanized pipe two.

[0007] A limiting block is fixedly installed on the outer wall of the top end of the galvanized pipe. The limiting block is located below the movable pipe, and the outer diameter of the limiting block is larger than the inner diameter of the bottom end of the movable pipe, which is used to limit the lower limit of the sliding of the movable pipe.

[0008] Furthermore, an extension pipe is fixedly installed at the bottom end of the second galvanized pipe, and several connecting rods arranged in a ring are fixedly installed on one side of the bottom end of the second galvanized pipe located on the extension pipe.

[0009] Furthermore, the top end of the galvanized pipe is provided with an annular groove, the inner wall of the top end of the galvanized pipe is provided with a plurality of rectangular grooves arranged in annular pattern, and the top end of the galvanized pipe is provided with a sealing structure.

[0010] Furthermore, the sealing structure includes a T-shaped sealing tube, the bottom outer wall of which is fixed in an annular groove one, and an annular groove two is opened at the top of the T-shaped sealing tube. Several rectangular sealing blocks arranged in annular arrangement are fixedly installed on the inner wall of the top of the T-shaped sealing tube, and a limiting groove is opened on the outer wall of the top of the rectangular sealing block.

[0011] Furthermore, the rectangular sealing block is adapted to and snapped into the rectangular groove, the second annular groove is adapted to and inserted into the extension tube, the outer wall of the extension tube is tightly fitted to the inner wall of the second annular groove, the connecting rod is adapted to and snapped into the limiting groove, and the outer wall of the connecting rod is tightly fitted to the inner wall of the limiting groove.

[0012] Furthermore, the inner wall of the first sealing ring is tightly fitted to the outer wall of the first galvanized pipe, and the first sealing ring is made of elastic rubber. The bottom end of the second sealing ring can contact and fit with the top end of the movable pipe, and the second sealing ring is also made of elastic rubber.

[0013] The beneficial effects of this utility model are:

[0014] 1. This easy-to-assemble galvanized pipe, through the threaded engagement of the movable pipe with external threaded pipe one and external threaded pipe two in the splicing structure, can quickly achieve the connection and fixation of galvanized pipe one and galvanized pipe two. The operation is simple, no complicated tools are required, and the splicing efficiency is greatly improved. At the same time, the limiting block can effectively limit the lower limit of the sliding of the movable pipe, prevent it from detaching from galvanized pipe one, and ensure the stability of the splicing process.

[0015] 2. This easily assembled galvanized pipe features a sealing structure where the annular groove of the T-shaped sealing pipe fits tightly with the extension of the second galvanized pipe, the rectangular sealing block engages with the rectangular groove of the first galvanized pipe, and the connecting rod fits tightly with the limiting groove of the rectangular sealing block. These multiple structures work together to effectively prevent leakage of the medium inside the pipe. The first sealing ring in the splicing structure fits tightly against the outer wall of the first galvanized pipe, and the second sealing ring can contact the top of the movable pipe. Both are made of elastic rubber, providing excellent elasticity and sealing performance, further enhancing the sealing effect at the splice. This design is suitable for various fluid transport scenarios.

[0016] 3. This easily assembled galvanized pipe provides a stable axial fixing force through the threaded connection between the external threaded pipe one, external threaded pipe two and the movable pipe, preventing relative displacement of the two galvanized pipes during use; at the same time, the snap-fit ​​engagement between the connecting rod and the limiting groove, as well as the snap-fit ​​engagement between the rectangular sealing block and the rectangular groove, restricts the circumferential rotation of the two galvanized pipes, making the overall connection more stable and improving the load-bearing capacity and safety of the structure.
