The first noise-reducing housing 3 and the second noise-reducing housing 4 are opened, and the compressor housing is covered by the first noise-reducing housing 3 and the second noise-reducing housing 4. The pressing block 113 is pressed to compress the return spring 115, and the pin 111 and the connecting rod 112 are inserted into the fixing seat 13. The pressing block 113 is released, and the elastic force of the return spring 115 causes the connecting rod 112 to move. The pin 111 is inserted into the fixing hole 14, so that the first noise-reducing housing 3 and the second noise-reducing housing 4 are quickly fixed. The limiting block 122 is inserted into the fixing seat 13, and the two ends of the limiting block 122 abut against the side of the connecting rod 112.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the rotating connector 6 includes a first connecting block 61, a rotating column 62, a U-shaped bracket 63, and a second connecting block 64. The first noise-reducing housing 3 has a first connecting block 61 on its side, and a rotating column 62 is provided in the middle of the side of the first connecting block 61. The second noise-reducing housing 4 has a second connecting block 64 on its side, and a U-shaped bracket 63 is connected to the side of the second connecting block 64.

[0035] By adopting the above technical solution, the rotating column 62 is inserted into the U-shaped bracket 63, so that the rotating column 62 can rotate in the U-shaped bracket 63. The first noise reduction housing 3 and the second noise reduction housing 4 rotate around the rotating column 62, so that the sides of the first noise reduction housing 3 and the second noise reduction housing 4 rotate. The structure is simple and the installation is convenient.

[0036] Specifically, the U-shaped bracket 63 engages with the rotating column 62, and the side of the U-shaped bracket 63 is in close contact with the side of the connecting block 61.

[0037] By adopting the above technical solution, it is ensured that the rotating column 62 can rotate in the U-shaped card holder 63, and the first noise reduction housing 3 and the second noise reduction housing 4 rotate around the rotating column 62.

[0038] In this embodiment, the rotating column 62 is inserted into the U-shaped bracket 63, allowing the rotating column 62 to rotate within the U-shaped bracket 63.

The structure is simple and the installation is convenient.

[0039] Example 3

[0040] The difference between this embodiment and embodiment 1 is that the fixing component 1 includes a first hook and loop fastener and a second hook and loop fastener, which are attached to each other and respectively disposed on the first noise reduction housing 3 and the second noise reduction housing 4.

[0041] In other words, the first and second noise-reducing housings 3 and 4 can also be made to fit together by directly using the first and second Velcro straps. The first and second Velcro straps have soft and rough sides, respectively, which achieves the desired effect. This structure is a conventional method in this field and will not be described in detail here.

[0042] Example 4

[0043] The difference between this embodiment and embodiment 1 is that the fixing component 1 is a snap-fit ​​structure, that is, the fixing effect between the first noise reduction shell 3 and the second noise reduction shell 4 can be achieved by snap-fit ​​insertion. The snap-fit ​​structure is preferably a plastic snap-fit.

[0044] The working principle and usage process of this utility model are as follows: When using this utility model, the rotating column 62 is inserted into the U-shaped bracket 63, allowing the rotating column 62 to rotate within the U-shaped bracket 63. The first noise-reducing housing 3 and the second noise-reducing housing 4 rotate around the rotating column 62, causing the sides of the first noise-reducing housing 3 and the second noise-reducing housing 4 to rotate. The structure is simple and the installation is convenient. The first noise-reducing housing 3 and the second noise-reducing housing 4 are fixed to the outer surface of the compressor. The first noise-reducing housing 3 and the second noise-reducing housing 4 are opened, and the compressor outer shell is covered by the first noise-reducing housing 3 and the second noise-reducing housing 4. Press down. Block 113 compresses the return spring 115, and the pin 111 and connecting rod 112 are inserted into the fixing seat 13. When the pressing block 113 is released, the elastic force of the return spring 115 causes the connecting rod 112 to move, and the pin 111 is inserted into the fixing hole 14, so that the first noise reduction housing 3 and the second noise reduction housing 4 are quickly fixed. The limiting block 122 is inserted into the fixing seat 13, and the two ends of the limiting block 122 abut against the side of the connecting rod 112. The locking block 123 is locked into the locking groove 15. The limiting component 12 limits the movement and prevents it from falling off, saving time and effort. The first sound-absorbing part 2 and the second sound-absorbing part 5 absorb noise.
