[0001] This utility model belongs to the field of pipeline connection technology, and specifically relates to a pipeline connection device. Background Technology

[0002] When connecting two pipes, flanges or similar structures are typically used to bolt the pipes together. This method is convenient, but when connecting pipes of different sizes, the flanges must first be connected to the pipes, and then the two flanges must be connected together to connect the pipes. It is not possible to directly replace the pressure plates of different sizes according to different pipe specifications to connect the pipes, which reduces the convenience of the pipe connection process. Therefore, we propose a pipe connection device. Utility Model Content

[0024] Please see Figure 1-4 This utility model provides a pipe connection device, including a guide seat 1. Symmetrically distributed connecting seats 2 are arranged on one side of the guide seat 1. The lower connecting seat 2 is fixedly connected to the guide seat 1, and the upper connecting seat 2 is slidably connected to the side wall of the guide seat 1. An arc-shaped channel 3 extending through the front and back is opened on the side wall of the two connecting seats 2 that are close to each other. Symmetrically distributed slots 13 are opened on the inner wall of the arc-shaped channel 3. An arc-shaped connecting plate is arranged inside the arc-shaped channel 3. Symmetrically distributed clamping plates 12 are fixed to the outer wall of the connecting plate, and the clamping plates 12 and the slots 13 engage with each other for connecting the connecting plate and the arc-shaped channel 3. A stop strip 14 is slidably connected to the outer wall of each connecting seat 2, and the stop strip 14 abuts against the clamping plate 12. The bottom end of the stop bar 14 is fixed with a pull plate 15. The pull plate 15 and the stop bar 14 are vertically arranged. An adjustment groove 16 is opened on one side wall of the connecting seat 2. A moving plate 17 is slidably connected between the two side walls of the adjustment groove 16. A limit strip 19 is fixed on one side wall of the moving plate 17 to limit the position of the pull plate 15, thereby fixing the position of the clamping plate 12. Multiple parallel moving springs 18 are fixed on the side wall of the moving plate 17 away from the limit strip 19 to further fix the position of the limit strip 19. The stop bar 14 and the pull plate 15 at the top limit the clamping plate 12 in the initial state. The position of the clamping plate 12 is further stabilized by the setting of the limit strip 19.

[0025] A fixed seat 5 is fixed to one side wall of the guide seat 1. A fixed channel is opened on the upper surface of the fixed seat 5 in the vertical direction. A threaded shaft 6 is rotatably connected to the inner wall of the fixed channel. A rotating plate 7 is fixed to the top of the threaded shaft 6. A threaded groove 10 is opened on the upper surface of the upper connecting seat 2. The bottom end of the threaded shaft 6 extends into the threaded groove 10. The threaded shaft 6 and the connecting seat 2 are connected by a threaded drive. The threaded shaft 6 is used to adjust the position of the connecting seat 2 and to press and fix the position between the two pipes.

[0026] The upper surface of the rotating plate has symmetrically distributed insertion holes 9 along the circumferential direction. One of the insertion holes 9 is equipped with a mounting bolt 8. The upper surface of the fixing seat 5 has a threaded groove 11. The mounting bolt 8 is threadedly connected to the threaded groove 11 to fix the position of the connecting seat 2.

[0027] This solution involves the following steps: When connecting pipes, rotating the mounting bolt 8 separates it from the threaded groove 11. Then, rotating the rotating plate 7 causes the threaded shaft 6 to rotate, which in turn moves the upper connecting seat 2 via threaded transmission. Next, the two pipes are placed between the two pressure plates 4. Rotating the rotating plate 7 again causes the threaded shaft 6 to rotate, which in turn moves the upper connecting seat 2 via threaded transmission, thus pressing the upper pressure plate 4 against the upper surface of the pipes to connect and fix them. Finally, tightening the mounting bolt 8 fixes the position of the rotating plate 7. This process can be repeated depending on the pipe size. When changing the size of the pressure plate 4, the moving plate 17 is pushed, which moves the limiting strip 19 so that the limiting strip 19 enters the adjusting groove 16. Then the pull plate 15 is moved, which moves the stop strip 14 so that the stop strip is misaligned with the clamping plate 12. Then the pressure plate 4 is moved, which moves the clamping plate 12 out of the clamping groove 13. The pressure plate 4 of the new size is moved, which moves the clamping plate 12 into the clamping groove 13. Then the stop strip 14 is moved upward, which limits the clamping plate 12. Then the moving plate 17 is released, and under the elastic force of the moving spring 18, the limiting strip 19 abuts and fixes the pull plate 15. Then the connection and fixing of the pipeline continues.
