[0033] like Figures 1 to 4 As shown, this embodiment proposes a car air conditioning pipeline connection structure, including a pipeline body 1 and an annular boss 2, the annular boss 2 is arranged at the pipe mouth of the pipeline body 1 and is coaxially arranged with the pipeline body 1, the annular boss 2 can be used to dock with an external joint, the annular boss 2 is hollow inside and connected with the pipeline body 1 to form a channel for the circulation of the refrigerant medium, and the annular boss 2 is provided with an arc portion 3, which can be used to guide the annular boss 2 to extend into the joint. By connecting the annular boss 2 with the pipeline body 1, a channel for the circulation of the refrigerant medium can be formed; by providing the arc portion 3 on the annular boss 2, on the one hand, the annular boss 2 can be guided to extend into the joint through the arc portion 3, and on the other hand, the phenomenon of scratching the inner wall of the joint when the annular boss 2 extends into the joint, resulting in leakage of the refrigerant medium, is avoided.

[0034] Preferably, the inner diameter of the annular boss 2 is equal to the outer diameter of the pipe body 1. Of course, according to actual conditions and specific requirements, the inner diameter of the annular boss 2 may also be smaller than the outer diameter of the pipe body 1, which is not the only limitation here.

[0035] For further information, see Figure 3 and Figure 4As shown, the arc portion 3 can be a circular chamfer, and the circular chamfer is arranged at the port of the annular boss. In this way, by setting the circular chamfer, the annular boss 2 can be guided to extend into the joint through the circular chamfer on the one hand, and on the other hand, the phenomenon of scratching the inner wall of the joint and causing the leakage of the refrigerant medium when the annular boss 2 extends into the joint is avoided. Preferably, the circumferential angle corresponding to the circular chamfer is 60°-90°. Specifically, the circular chamfer can be 60°, 65°, 70°, 75°, 80°, 85°, 90°, etc. In the present embodiment, the circular chamfer is 90°, which is set to 90°, so as to facilitate machining and improve machining efficiency.
