the outer diameter of the outer pipe connecting section is smaller than or equal to the inner diameter of the hoop;
the outer pipe connecting section is provided with two centrosymmetric kidney-shaped grooves along the axial direction from the end part; the kidney-shaped groove 201 is positioned in the locking area of the outer pipe connecting section and the hoop;
the hoop is connected to a locking area on the outer pipe connecting section.
Specifically, the end part of the outer pipe connecting section is also provided with a positioning groove;
and a boss matched with the positioning groove on the outer pipe connecting section is arranged on the outer wall of the inner pipe connecting section.
Preferably, the center line of the positioning groove is at 90 degrees to the center line of the kidney-shaped groove in the radial direction.
Specifically, a clamping groove is formed in the end part of the inner pipe connecting section; the central line of the clamping groove is collinear with the central line of the boss.
Specifically, the pipe diameter of the outer pipe connecting section is larger than that of the outer pipe body.
The embodiment of the utility model provides a beneficial effect that technical scheme brought is:
1) the pipe part in the fitting area of the hoop is divided into two sections of separated semicircular pipes by arranging the kidney-shaped groove, so that the rigidity of the pipe in the hoop locking area is reduced, the deformation amount of the pipe during locking of the hoop can be increased, tight fitting between the inner pipe and the outer pipe is ensured, and the air tightness of pipe connection is increased;
2) the relative positions of the two pipes can be accurately positioned by matching the positioning groove with the boss;
3) through set up the draw-in groove at inner tube tip, when the mould of being convenient for processes the inner tube boss, carry out the accurate location of position, improve boss position accuracy.
