[0025] The inner wall of fixed frame 2 is provided with thread groove 9, and outer thread 10 is fixedly installed on the periphery of support frame 3, and outer thread 10 is threadedly connected with thread groove 9;

[0026] Multiple fixed holes 14 are formed on the periphery of movable cylinder 12, and movable cylinder 12 is fixedly connected with fixed cylinder 5 through fixing ring 11;

[0027] Two filter screens 18 are fixedly installed on the inside of support cylinder 7, and the two filter screens 18 are located on the two sides of sound attenuation frame 16 respectively;

[0028] Supporting cotton 15 is fixedly installed on the periphery of support cylinder 7, and the periphery of supporting cotton 15 is attached to the inner wall of support frame 3.

[0029] The working principle of the refrigerator compressor inner exhaust pipe with sound attenuation and vibration reduction structure based on the embodiment is as follows: by connecting and fixing one end of fixed pipe 1 with air conditioner compressor, air conditioner compressor can discharge air into fixed pipe 1, gas is discharged into fixed frame 2 through fixed pipe 1, the gas flows through multiple flow guide rings 13 to the right, part of the gas is guided outward by flow guide ring 13, part of the gas is guided to the outside of movable cylinder 12 through fixed hole 14, to avoid the case that the gas introduced into fixed frame 2 expands rapidly to generate noise and vibration, then the gas is guided to the right side of flow guide ring 13, and fixing ring 11 can support and fix movable cylinder 12 and fixed cylinder 5;

[0030] By allowing the gas to flow to the right through the through hole 17 inside the muffler 16, the muffler 16 and the through hole 17 can further eliminate noise from the gas, effectively silencing and damping the gas. The filter screen 18 can protect the muffler 16, preventing impurities from entering the inside of the muffler 16 and causing blockage. The support frame 3 guides the gas into the exhaust pipe body 4, and the exhaust pipe body 4 discharges the gas, facilitating the exhaust operation of the air conditioning compressor.

[0031] By rotating the support frame 3, the support frame 3 is separated from the fixed frame 2, making it easy to remove the fixed cylinder 5 and the support cylinder 7. This facilitates disassembly, cleaning, and maintenance. The guide ring 6 guides one side of the fixed frame 2, making it easy to insert the fixed cylinder 5 into the inside of the fixed frame 2. By inserting the support cylinder 7 into the inside of the support frame 3, the support cotton 15 is used to support and fix the support cylinder 7 against the inner wall of the support frame 3. At the same time, it reduces noise and vibration of the air flowing through the outside of the support cylinder 7.

[0032] By using the support ring 8 to guide one side of the fixed frame 2, it is easy to insert one side of the support frame 3 into the inside of the fixed frame 2. Then, by rotating the support frame 3, the external thread 10 is rotated synchronously, so that the external thread 10 and the thread groove 9 are threadedly connected. This makes it easy to fix the support frame 3 and the fixed frame 2. When fixing, the support ring 8 can be moved to the left to squeeze and support one side of the fixed cylinder 5, so that the guide ring 6 fits against the inner wall of the fixed frame 2, which makes it easy to limit and fix the fixed cylinder 5, and facilitates disassembly and installation, cleaning and maintenance.

[0033] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
