The invention relates to the technical field of conduit
polytetrafluoroethylene linings, in particular to a conduit
polytetrafluoroethylene lining connecting piece with a modular disassembly and
assembly structure, which comprises a conduit body and an adapting mechanism, the adapting mechanism is arranged on the inner side of the conduit body, and a
contact mechanism is arranged on the inner side of the adapting mechanism. An adjusting air
pipe is arranged on the side, away from the
contact mechanism, of the inner side of the adapting mechanism, the adapting mechanism comprises a positioning outer cylinder sleeve and a limiting inner
cylinder set, the positioning outer cylinder sleeve is arranged on the inner side of the
catheter body, the limiting inner
cylinder set is arranged on the inner side of the positioning outer cylinder sleeve, and the
contact mechanism comprises a clamping clamping sleeve and an adapting soft sleeve. And the clamping card sleeve is arranged on the inner side of the limiting inner cylinder group. The guide
pipe teflon lining connecting piece with the modular disassembly and
assembly structure has the advantages that the guide
pipe teflon lining connecting piece is of a structure suitable for different shapes of teflon linings, so that stable support cannot be provided when the guide pipe needs to be provided with the teflon linings of different shapes, and the flexibility is reduced when the guide pipe is provided with the teflon linings of different types.
