Furthermore, the upper end of the inner wall of the copper pipe sleeve is provided with a plurality of buckling teeth in parallel, and the lower end of the inner wall of the copper pipe sleeve is provided with a plurality of barb teeth in parallel.
Furthermore, a plurality of conical teeth matched with the barb teeth are arranged on the outer wall of the filling piece in parallel.
Further, the diameter of the outer wall of the filling piece is uniformly increased from top to bottom.
Further, the outer wall of the filling seat is hexagonal.
Further, the diameter of the outer wall of the tightening piece is uniformly reduced from top to bottom.
Further, the tightening piece comprises tightening pieces which are arranged at equal intervals on the circumference.
The utility model has the advantages that:
the utility model relates to a hydraulic rubber tube assembly, which has simple structure, and can fill the space between the copper tube sleeve and the elbow joint through the filling piece to ensure the tight fixation of the rubber tube; the rubber tube is fixed in advance through the tightening piece and then is in butt joint with the elbow joint, so that the installation is convenient.
