Beschreibung
Zusammenfassung:	The utility model relates to a composite pipe joint structure which comprises a main pipeline, an auxiliary pipeline is movably connected in the main pipeline, and installation assemblies are arranged on the outer surface of the main pipeline and the outer surface of the auxiliary pipeline. The installation assembly comprises a main fixing block, the main fixing block is fixedly connected to the outer surface of the main pipeline, two main sealing strips are movably connected into the main fixing block, and an auxiliary fixing block is arranged on the outer surface of the auxiliary pipeline. According to the composite pipe joint structure, when a main pipe and an auxiliary pipe need to be connected together, after the auxiliary pipe is clamped into an annular positioning groove in the main pipe through an annular positioning block, an upper cover plate and a lower cover plate are located in a main fixing block and an auxiliary fixing block through a main sealing strip and an auxiliary sealing strip; and then
