The connecting part 2 is provided at the pipe opening of the pipeline body 1, and the pipeline limiting ring 3 is fixedly connected to the surface of the pipeline body 1.

[0030] Please see Figure 1 and Figure 2 Embodiment 1 of this utility model provides a pipeline, including a pipeline connecting fitting 4 and a pipeline as described above, and also includes a pipeline clamping assembly 9. The pipe openings of the pipeline connecting fitting 4 are all connected to the pipeline body 1. The pipeline body 1 is inserted into the pipeline connecting fitting 4 for connection. One end of the pipeline clamping assembly 9 is clamped to the pipeline body 1, and the other end of the pipeline clamping assembly 9 is clamped to the pipeline connecting fitting 4.

The clamping frame 904 is fixedly connected to the surfaces of the two threaded rods 902. The two sides of the clamping frame 904 are respectively connected to the limiting nut 904 and the limiting piece 905. The adjustable clamping ring 906 is fixedly connected to the top of the two clamping frames 904. One of the adjustable clamping rings 906 is connected to the pipe body 1, and the other adjustable clamping ring 906 is connected to the pipe connecting fitting 4. The pipeline body 1 is provided with a connecting part 2, which is located at the connection between the pipeline body 1 and the pipeline connecting fitting 4. The pipeline connecting fitting 4 has snap-fit ​​parts 6 at both ends. The connecting part 2 is inserted into the snap-fit ​​parts 6 for connection. The width of the snap-fit ​​parts 6 matches the width of the connecting part 2. The connecting part 2 includes several striped protrusions formed by grinding.

[0033] Example 2

[0034] The difference between Embodiment 2 and Embodiment 1 is that, based on Embodiment 1, in Embodiment 2, a pipe joint is provided on the outside of the connection between the pipeline body 1 and the pipeline connecting fitting 4.

[0035] The middle layer of the steel-plastic composite ring 5 is a high-strength steel skeleton, and both the inner and outer layers of the steel-plastic composite ring 5 are thermoplastic composite layers. During pipeline installation and use, the installer adjusts the heating time of the welding machine according to the electrofusion parameters of the pipeline connection fitting 4 and the steel-plastic composite ring 5, and inserts the welding machine into the electrofusion inlet 7 for welding to make the connection tighter and ensure airtightness.

[0036] The other structures of this embodiment 2 are the same as those of embodiment 1, and will not be described again here.

[0037] Example 3

[0038] Based on Embodiments 1 and 2, the shape and overall symmetry of a pipeline in Embodiment 1 or 2 are described. In this Embodiment 3, a pipeline is an L-shaped structure with the middle of the connecting fitting as the axis of symmetry, symmetrical at both ends. The structures at both ends of the pipeline and the connection methods between the connecting fittings 4 and the pipeline body 1 are the same, i.e., the two ends of the pipeline are symmetrical, each equipped with a connecting part 2, a pipeline limiting ring 3, a steel-plastic composite ring 5, a snap-fit ​​part 6, an electrofusion weld inlet 7, a connecting fitting limiting ring 8, and a pipeline clamping assembly 9. It should be noted that... Figure 1 Only one clamping pipe assembly 9 is specified in the text. A clamping pipe assembly 9 is also provided at the connection point between the other end of pipe assembly 4 and pipe body 1, but... Figure 1 It is not shown in the middle.

[0039] The other structures of this embodiment 3 are the same as those of embodiment 1 or embodiment 2, and will not be described again here.

[0040] In the actual installation of a pipeline according to an embodiment of this utility model, the connecting part 2 is inserted into the snap-fit ​​part 6 for initial clamping and positioning. One adjustable clamping ring 906 abuts against the pipeline limiting ring 3, and another adjustable clamping ring 906 abuts against the connecting fitting limiting ring 8. The two adjustable clamping rings 906 are adjusted according to the diameter of the pipeline or fitting being clamped for initial clamping. After initial clamping, the stability and reliability of the adjustable clamping rings 906 are further enhanced by the adjustable clamping protrusion 909. After clamping, the threaded sleeve 90 is rotated... 1. The threaded rod 902 moves left and right, thereby moving the clamping frame 904 and the adjustable clamping ring 906 left and right. This pushes the adjustable clamping ring 906 towards the pipe limiting ring 3 and the connecting pipe fitting limiting ring 8. The installer then adjusts the heating time of the welding machine according to the electrofusion parameters of the pipe connecting fitting 4 and the steel-plastic composite ring 5, and inserts it into the electrofusion inlet 7 for welding, further improving the tightness of the connection. The steel-plastic composite ring 5 is fixedly connected to the pipe end of the pipe connecting fitting 4, making the pipe connection structure stronger and more corrosion resistant.

[0041] In summary, this invention, based on the initial alignment and clamping connection of the pipe body and the pipe connecting fittings, allows manual adjustment of the rotation of the threaded sleeve in the clamping pipe assembly, causing the threaded rod to retract inward. The limiting nut and limiting plate keep the clamping frame fixed, thereby clamping the two adjustable clamping rings tightly against the connection between the pipe body and the pipe connecting fittings from the periphery towards the center, further tightening the connection between the pipe body and the pipe connecting fittings and preventing detachment. This facilitates installation, requires less technical skill from operators, and ensures a tighter connection between pipes, avoiding potential leakage problems caused by loose connections or detachment of pipes. Furthermore, the use of some steel-plastic composite materials improves the structural strength of the connection between the pipe connecting fittings and the pipe body.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
