In the technical scheme, the access section with stub-out of connector can be converted mutually, for here, access section
Outer diameter is greater than the outer diameter of stub-out, and the inside that air-conditioning duct is connected to access section is fixed, and one is used between the long tube and boss of pipeline
The mode of body casting is combined together, and is avoided apertured generation, is strengthened leakproofness, is provided with protrusion just in the periphery of boss
It is connect in air-conditioning pipe fitting, protrusion is stuck in the groove of air-conditioning pipe fitting, so that the company between air-conditioner pipe and air-conditioning pipe fitting
Connect stronger, leakproofness is better.
Further improvement of the utility model, the outer diameter of the access section of connector are greater than the outer diameter of stub-out, and access section is whole
Structure is regular polygon, and the overall structure of stub-out is cylinder, and access section overall structure is that regular polygon screws convenient for spanner,
The overall structure of stub-out is the inside that cylinder is easily installed air-conditioning duct.
Further improvement of the utility model, access section overall structure are octagon, meet general mechanical equipment
Design principle.
Further improvement of the utility model, the inner transverse of the access section of connector are provided with along the recessed of connector direction
Slot, the periphery of stub-out are provided with screw thread, and the setting of groove and screw thread is matched with the protrusion and screw thread of pipeline periphery,
So that the connection between connector and pipeline is even closer securely, gap is reduced.
Further improvement of the utility model, the protrusion of pipeline are uniformly arranged on the periphery of boss, it is raised between away from
Equal from two-by-two, protrusion matches with the groove inside connector access section.
The utility model has the beneficial effects that the no-welding air-conditioning duct composite structure that the utility model discloses can make sky
Adjust pipeline between use non-solder connection type, save the welding procedure between air-conditioning duct in this way, reduce manually at
This, reduce the probability for causing pipeline to reveal because of welding makes so that the connection between pipeline is simpler, quick, efficient
The production for obtaining entire air conditioning for automobiles reduces costs, and improves quality.
