[0002] With the continuous development of industry and construction, the requirements for pipeline systems are getting higher and higher. In the case of narrow space but a large turning radius, elbows are needed to change the direction of the pipeline and realize the connection between different pipelines. In order to adapt to various complex application scenarios, a 90-degree extended elbow is proposed.

[0003] Chinese utility model patent announcement number: CN 213954657 U3, discloses: a 90-degree plastic curved elbow, which uses a limit groove, a rubber pad and a straight pipe in combination, so that when the straight pipe spirally rotates inside the limit groove, it can squeeze the rubber pad and fit tightly against the inner wall of the limit groove, thereby improving the sealing performance. However, the 90-degree plastic curved elbow is not designed with a pipe telescopic mechanism, which easily leads to greater overall limitations during connection. In addition, the 90-degree plastic curved elbow is not designed with multiple connection structures, which only leads to greater overall limitations when the entire elbow is connected.
