[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a vibration-damping and noise-reducing scroll compressor, including a scroll compressor body 14, a sound insulation cylinder 1, and a damping rubber support 2. The damping rubber support 2 is installed on the bottom surface of the scroll compressor body 14. The sound insulation cylinder 1 is sleeved on the outside of the scroll compressor body 14. A sound insulation pad 15 is installed inside the sound insulation cylinder 1. Multiple thickened parts 19 are protruding on the inner wall surface of the sound insulation cylinder 1. The thickened parts 19 are arranged opposite each other and all pass through the sound insulation pad 15. The outer wall surface of the sound insulation cylinder 1 is recessed at the thickened parts 19 to form a connecting groove 9. Each thickened part 19 is provided with a positioning hole. Each positioning hole is provided with a positioning post 10. One end of each positioning post 10 extends into the interior of the sound insulation cylinder 1 and is provided with a clamping plate 17. The sound insulation cylinder 1 is fixed to the scroll compressor body 14 by the clamping plate 17. Bolts 8 that press the positioning posts 10 are threaded into the connecting grooves 9. Arc-shaped clamping plates 7 are provided on the outside of the two bolts 8.

[0024] In this embodiment, the outer wall of the sound insulation cylinder 1 is vertically provided with an installation port 13 that penetrates the outer wall of the sound insulation cylinder 1 and the sound insulation pad 15. A cover plate 5 is provided in the installation port 13. A sound insulation strip 12 is installed on the inner side of the cover plate 5. The sound insulation strip 12 enters into the sound insulation pad 15 and fits against the sound insulation pad 15. The outer side of the cover plate 5 is provided with through holes that penetrate the cover plate 5 and the sound insulation strip 12 at the air inlet and outlet 6 of the scroll compressor body 14. The cover plate 5 is sleeved on the outside of the air inlet and outlet 6 through the through holes and enters into the installation port 13. The inner side of the arc-shaped clamp 7 abuts against the outer side of the cover plate 5, and the two ends of the arc-shaped clamp 7 are provided with connecting holes. The connecting holes are sleeved on the outside of the bolt 8.

[0025] The inner wall of the connecting hole is provided with threads, which can be threaded with the bolt to ensure the firmness of subsequent installation.

[0026] In this embodiment, the mounting port 13 is provided with positioning grooves 11 on both sides, and the cover plate 5 protrudes on both sides to form positioning parts. The positioning parts are inserted into the positioning grooves 11. The positioning grooves and positioning parts can restrict the cover plate and prevent the cover plate from entering the interior of the sound insulation tube. Also, after the arc-shaped clamp is pressed against the cover plate from the outside, the positioning parts on the cover plate can abut against the positioning groove to ensure the stability of the installation.

[0027] In this embodiment, the positioning holes and positioning posts 10 are both polygonal in cross-section, and each positioning post 10 is fitted with a compression spring 18. One end of each compression spring 18 is mounted on the clamping plate 17, and the other end is mounted on the thickened part 19. The compression springs 18 are all in a stretched state.

[0028] In this embodiment, two clamping plates 17 are combined to form a clamping ring, and the clamping plates 17 are both located at the junction of the exhaust end and the intake end of the scroll compressor body 14.

[0029] In this embodiment, a limiting part 20 protrudes from the top surface of the inner cavity of the sound insulation cylinder 1. The limiting part 20 passes through the sound insulation pad 15 and is fitted with a rubber layer 16. The rubber layer 16 is positioned to abut against the top surface of the scroll compressor body 14.

[0030] In this embodiment, the top surface of the soundproof cylinder 1 is provided with a plurality of air inlets 3 that penetrate the soundproof cylinder 1 and the soundproof pad 15, and the bottom surface of the soundproof cylinder 1 is provided with a plurality of air outlets 4 that penetrate the soundproof cylinder 1 and the soundproof pad 15.

[0031] The top of the soundproof cylinder can be fitted with a silent cooling fan, which is positioned directly opposite the air inlet. The air generated by the silent cooling fan can pass through the outer wall of the scroll compressor body through the soundproof pad until it is discharged from the air outlet, thus ensuring the heat dissipation effect of the scroll compressor body.

[0032] In this embodiment, the soundproof cylinder 1 is made of fiberglass board, and the soundproof pad 15 is made of soundproof felt. Fiberglass board is a rigid material that can provide sound insulation while also offering protection, thus increasing safety during use.

[0033] During installation, the bolts need to be unscrewed, and the arc-shaped clamping plate and cover plate need to be removed. After the bolts are removed, the positioning column can move outward by the rebound of the compression spring. The movement of the positioning column drives the clamping plate, causing the clamping plates to open. At this time, the sound insulation cylinder can be fitted onto the outside of the scroll compressor body from top to bottom. The sound insulation cylinder can pass smoothly through the outside of the air inlet and outlet through the open installation port, avoiding obstruction.

[0034] After the above is completed, the cover plate is fitted onto the outside of the air inlet and outlet through the through hole and enters the installation port. The positioning part on the cover plate can be inserted into the positioning groove. After the arc-shaped clamp plate is set outside the cover plate, the connecting holes at both ends of the arc-shaped clamp plate can be aligned with the connecting groove. At this time, the bolt is threaded through the connecting hole and connected to the connecting groove. The bolt can press the positioning column inward, causing the positioning column to move inward along the positioning hole and press the clamping plate, so that the clamping plate comes together and clamps and fixes itself at the junction of the air inlet end and the air outlet end of the scroll compressor body (the diameter of the air inlet end is larger than that of the air outlet end, so that the top surface of the clamping plate is on the bottom surface of the air inlet end, preventing the clamping plate from moving upward). The rubber layer and the limiting part can limit the descent of the sound insulation cover, so that a ring-shaped ventilation channel is formed between the sound insulation pad and the scroll compressor body. The arc-shaped clamp plate can be fixed simultaneously by the bolt, which greatly increases the convenience of installation and disassembly.

[0035] By combining sound insulation cylinders and sound insulation pads, a double-layer sound insulation effect can be achieved, and the installation opening can be sealed by cover plates and sound insulation strips to ensure the quality of sound insulation.

[0036] During the operation of the scroll compressor, the vibration energy generated is reduced by the damping rubber support to increase operational safety.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
