That is, a resistance wire is set inside the pipe mouth, and the external pipe to be connected is plugged into the inside of the electric fusion pipe. The resistance wire is powered by a power supply plugged into the electric fusion pipe, which heats up and melts the plugged pipe inside to achieve connection.

[0003] At present, when connecting pipelines to electric fusion pipe fittings, the outer ring size of the plug-in pipe usually has a slight error with the specified size. Workers are often required to grind off a part of the outer wall of the pipe mouth of the plug-in pipe to make it match the inner size of the electric fusion pipe fitting. However, the pipe grinding operation often requires the use of additional electric grinding tools, which is inconvenient to use and operate, affecting the connection efficiency. In addition, it is easy to over-grind the pipe during grinding, affecting the connection effect. In addition, when plugging the external power supply line into the electric fusion pipe, it is easy to become loose, requiring multiple manual adjustments, and the stability is insufficient.

[0004] Therefore, there is a need for a high-voltage electric fusion pipe fitting that is easy to connect, stable in operation, and quick to connect. Utility Model Content
