Abstract:
A movable connection pipe assembly, comprising a connector body (1), a nut (3) which is sleeved on the connecting portion (1a) of the connector body (1), a retaining ring (1a1) which protrudes from the outer side of the connecting portion (1a), a shoulder (3a) which protrudes from the inner side of the nut (3), a gasket (4) which is mounted in the nut (3), a ferrule (5) which is provided between the connecting portion (1a) and the nut (3), and a blocker ring (6) which is clamped on the outer side of the connecting portion (1). The ferrule (5) is rotatably sleeved on the connecting portion (1a) and is limited between the retaining ring (1a1) and the blocker ring (6), and the outer side surface of the ferrule (5) is provided with a limiting protrusion (5a). The limiting protrusion (5a) is located between the shoulder (3a) and the gasket (4), and the shoulder (3a) can abut against the inner end surface of the limiting protrusion (5a). The gasket (4) is in contact with the outer end surface of the limiting protrusion (5a). The arrangement of the ferrule in the movable connection assembly enables relative rotation between the nut and the connector body even after the nut is tightened.
