Description

Technical Field

[0001] This utility model relates to the field of welded pipe joints, and in particular to a welded pipe joint structure that can be quickly connected. Background Technology

[0002] Welded pipe is a type of steel pipe made by rolling steel plates or strips into shape and then welding them. Due to its high production efficiency, low cost, and diverse specifications, welded pipe plays an important role in many industries such as construction, pipeline transportation, machinery manufacturing, and oil and gas.

[0003] To ensure a tight seal, two sections of welded pipe are typically joined together by welding. This requires an external welding machine or a flange connection. However, flange connections require multiple bolts for fastening, increasing costs and necessitating the use of specialized tools, making the process cumbersome. Utility Model Content

[0006] As a further description of the above technical solution:

[0007] The positions of the plurality of hollowed-out grooves correspond to the positions of the plurality of limiting grooves, and the limiting grooves are J-shaped.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the first welded pipe is provided with external threads, and the inner wall of the rotating ring is provided with internal threads.

[0010] As a further description of the above technical solution:

[0014] As a further description of the above technical solution:

[0015] The positioning ring has a T-shaped cross-section, and the positioning groove has a T-shaped cross-section.

[0016] This utility model has the following beneficial effects:

[0017] 1. Before connecting two welded pipe sections, one end of the collar with multiple limiting blocks extends outside the first connector. When the two welded pipe sections are joined, the multiple limiting blocks are inserted into the multiple limiting grooves respectively. Then, the collar is rotated clockwise to drive the multiple limiting blocks to rotate along the multiple limiting grooves respectively. When it cannot rotate, the rotating ring is rotated to move the collar away from the second connector. At this time, the multiple limiting blocks will enter the end of the limiting groove as the collar moves. During this process, the first connector and the first welded pipe approach the second connector. After the first connector and the second connector are in contact, the rotating ring is rotated again. The multiple limiting blocks drive the second connector to press tightly against the first connector. At this time, the first welded pipe and the second welded pipe are connected. Rotating the rotating ring in the opposite direction, the same principle can separate the first welded pipe and the second welded pipe. Disassembly and assembly are convenient and quick, without the need for a welding machine or multiple sets of bolts, and without the need for external tools. The operation is simple and the connection efficiency is high.

[0018] 2. Multiple protrusions are provided on the outer wall of the rotating ring, and multiple grooves are opened on the outer wall of the collar to increase the friction between the rotating ring and the collar surface, facilitating rotation. A sealing ring is provided at the connection between the first connector and the second connector to ensure the sealing performance after the first welded pipe and the second welded pipe are connected.

Detailed Implementation

[0029] Reference Figure 1-8 This utility model provides a quick-connection welded pipe joint structure, including a first welded pipe 1, one end of which is fixedly connected to a first connector 2. The outer wall of the first connector 2 has a hollow groove 3, and there are multiple hollow grooves 3. The outer wall of the first connector 2 is threaded with a rotating ring 4, and the outer wall of the rotating ring 4 is fixedly connected to a positioning ring 5. The positioning ring 5 has a T-shaped cross-section. The outer wall of the first connector 2 is fitted with a collar 6, and the inner wall of the collar 6 is fixedly connected to a limiting block 7, and there are multiple limiting blocks 7. The outer wall of the collar 6 has a positioning groove 8, and the positioning groove 8 has a T-shaped cross-section. The positioning ring 5 is located inside the positioning groove 8. A second welded pipe 9 is provided on the right side of the first welded pipe 1, one end of which is fixedly connected to a second connector 10. The outer wall of the second connector 10 has a limiting groove 11, and there are multiple limiting grooves 11. Multiple limiting blocks 7 are located inside multiple limiting grooves 11.

[0030] Before connecting the two welded pipe sections, one end of the collar 6 connected to multiple limiting blocks 7 extends outside the first connector 2. When the two welded pipe sections are joined, the multiple limiting blocks 7 are inserted into multiple limiting grooves 11 respectively. Then, the collar 6 is rotated clockwise to drive the multiple limiting blocks 7 to rotate along the multiple limiting grooves 11 respectively. When it cannot rotate, the rotating ring 4 is rotated to drive the collar 6 to move away from the second connector 10. At this time, the multiple limiting blocks 7 will enter the end of the limiting groove 11 as the collar 6 moves. During this process, the first connector 2 and the first welded pipe 1 approach the second connector 10. After the first connector 2 and the second connector 10 are in contact, the rotating ring 4 is rotated again. The multiple limiting blocks 7 drive the second connector 10 to be in close contact with the first connector 2. At this time, the first welded pipe 1 and the second welded pipe 9 are connected. Rotating the rotating ring 4 in the opposite direction works on the same principle, but the first welded pipe 1 and the second welded pipe 9 are separated. The disassembly and assembly are convenient and quick, without the need for a welding machine or multiple sets of bolts, and without the need for external tools. The operation is simple and the connection efficiency is high.

[0031] The positions of the multiple hollow grooves 3 correspond to the positions of the multiple limiting grooves 11. The limiting grooves 11 are J-shaped. The outer wall of the first welded pipe 1 is provided with external threads 12, and the inner wall of the rotating ring 4 is provided with internal threads 13.

[0032] The outer wall of the rotating ring 4 is provided with protrusions 14, and there are multiple protrusions 14. The outer wall of the collar 6 is provided with grooves 15, and there are multiple grooves 15. The outer wall of the first connector 2 is provided with a first sealing groove 16, the outer wall of the second connector 10 is provided with a second sealing groove 17, and a sealing ring 18 is provided at the contact point between the first connector 2 and the second connector 10.

[0033] Multiple protrusions 14 are provided on the outer wall of the rotating ring 4, and multiple grooves 15 are provided on the outer wall of the collar 6 to increase the friction between the surfaces of the rotating ring 4 and the collar 6, so as to facilitate rotation. A sealing ring 18 is provided at the connection between the first connector 2 and the second connector 10 to ensure the sealing after the first welded pipe 1 and the second welded pipe 9 are connected.

[0034] Working principle: Before connecting the two welded pipe sections, one end of the collar 6 connected to multiple limiting blocks 7 extends outside the first connector 2. When the two welded pipe sections are joined, the multiple limiting blocks 7 are inserted into multiple limiting grooves 11 respectively. Then, the collar 6 is rotated clockwise to drive the multiple limiting blocks 7 to rotate along the multiple limiting grooves 11 respectively. When it cannot rotate, the rotating ring 4 is rotated to drive the collar 6 to move away from the second connector 10. At this time, the multiple limiting blocks 7 will enter the end of the limiting groove 11 as the collar 6 moves. During this process, the first connector 2 and the first welded pipe 1 approach the second connector 10 until the first connector 2 and the second connector 10 are in contact. Then, the rotating ring 4 continues to rotate, and multiple limit blocks 7 drive the second connector 10 to be in close contact with the first connector 2. At this time, the first welded pipe 1 and the second welded pipe 9 are connected. The rotating ring 4 is rotated in the opposite direction. The same principle applies, but the first welded pipe 1 and the second welded pipe 9 are separated. The disassembly and assembly are convenient and quick. There is no need to use a welding machine or multiple sets of bolts, and no external tools are required. The operation is simple and the connection efficiency is high.
