Abstract
A fast double-connector device comprises a threaded connector, a copper tube, a locking nut, a seal ring made of elastic materials, a metal ring with a notch and a fastening nut. The copper tube is inserted into the threaded connector. One end of a fastening portion of the fastening nut is provided with external threads. One end of the seal ring is attached to the end portion of the threaded connector. The other end of the seal ring is matched with the fastening portion of the fastening nut. The metal ring is arranged on the top of the fastening nut. The locking nut is screwed with the fastening nut. The metal ring with the notch is matched with the locking nut and the copper tube. The fastening nut tightly wraps the seal ring on the copper tube and is tightly matched with the threaded connector so as to achieve the purpose of sealing. The locking nut acts on the metal ring. A physical groove clamp slot is formed in the outer circumferential surface of the copper tube under the action of the locking nut and the metal ring so as to effectively prevent the copper tube from moving along the threaded connector in the axial direction. The fast double-connector device overcomes the defect that the copper tube is prone to leakage when flaring processing is carried out to the copper tube. Moreover, the fast double-connector device is convenient to assemble with no need of special tools.
