[0021] The replaceable copper tube structure for refrigerator compressor provides two technical solutions:

[0022] like Figure 1 and 2 The first embodiment is shown: it includes a compressor body 1 and a butt copper tube 4, an external tube 2 is arranged on the compressor body 1, and a mounting mechanism 3 is arranged at the end of the external tube 2, the mounting mechanism 3 is used to connect the external tube 2 with the butt copper tube 4, and a sealing sleeve 7 for sealing is arranged between the external tube 2 and the butt copper tube 4, the mounting mechanism 3 includes a round sleeve 31, the round sleeve 31 is fixedly connected to the surface of the external tube 2, the inner diameter of the round sleeve 31 is larger than the outer diameter of the external tube 2, so that a cavity is formed between the external tube 2 and the round sleeve 31, four through grooves 32 are equidistantly provided on the circumference of the surface of the round sleeve 31, a fixing rod 33 is fixedly connected inside the through groove 32, a pressing block 34 is fixedly connected to the surface of the fixing rod 33, a thread 35 is arranged on the surface of the round sleeve 31, and a locking sleeve 36 is threadedly connected at the thread 35, the locking sleeve 36 is used to push the four pressing blocks 34 to rotate, the locking sleeve 36 is composed of a hand-held portion and a tapered portion, an inclined surface is arranged on the inner side of the pressing block 34, and the tapered portion cooperates with the inclined surface.

[0023] When installing the butt copper tube 4, the installation mechanism 3 is operated by simply rotating the locking sleeve 36 to complete the installation, which is also convenient for disassembly, and the stability after installation is high, which improves the convenience of replacing the butt copper tube 4.

[0024] like Figure 2 and 3 The second embodiment is shown, and the main difference from the first embodiment is that the butt ends of the external tube 2 and the butt copper tube 4 are fixedly connected with a circular ring disk 5, the left side of the circular ring disk 5 on the butt copper tube 4 is fixedly connected with an extension tube 6, and the left end face of the extension tube 6 is provided with an oblique chamfer, and the outer diameter of the extension tube 6 is interference fit with the inner diameter of the external tube 2.
