Sealed connection assembly

Abstract

A sealed connection assembly includes: a coupling body, wherein the coupling body is cylindrical, an outer part of the coupling body is provided with an external thread, a nut, an inner side of the nut is provided with an internal thread, and the internal thread is adapted to the external thread; an upper end of the internal thread is further provided with an inwardly inclined inner slope; a sealing ring, wherein an inner wall of the sealing ring is further provided with a sealing groove, and the sealing groove is further provided with a flexible component. The above-mentioned technical solution can provide a physical structure for cooperating with a metal conduit for sealing, the sealing ring is compressed and extended by means of the internal threaded part of the nut, and the flexible component is protected by means of designing the sealing groove, thereby prolonging the service life of a connecting device.
