Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline connection fixing structure. Background Art
[0002] In actual engineering applications and testing pipelines, pipes are connected and sealed using standard joints. However, it is often necessary to cut a round pipe due to damage and then reconnect it, or to connect another round pipe to it. The damaged round pipe does not have a standard connection interface, and the round pipe connected to the equipment is generally long, making it inconvenient to disassemble the entire section for secondary processing or replacement.
[0003] Generally, when encountering the above situation, a plastic tube with a thicker diameter (larger than the outer diameter of the round tube to be connected) is put on the straight pipe, and then it is tightened with a clamp to play the role of connection. The plastic tube with a thicker diameter is put on the straight pipe and then tightened with a clamp. Generally, it plays the role of temporary connection. The plastic tube is relatively thin and has poor weather resistance. At the same time, the sealing reliability of the clamp is not high. Therefore, a pipeline connection fixing structure is urgently needed. Utility Model Content
