Anti-loosening pads 5 are fixedly installed at both the left and right ends of the sound insulation pipe 1. Anti-slip grooves 6 are opened at one end of the anti-loosening pad 5 away from the sound insulation pipe 1. Threaded connection grooves 7 are arranged at both the left and right ends inside the sound insulation pipe 1. The anti-loosening pad 5 is made of nitrile rubber. The anti-slip grooves 6 are distributed in an annular array. A spherical cavity 12 is opened inside the anti-loosening pad 5. The spherical cavities 12 are distributed in an annular array. The anti-loosening pad 5 is designed in an annular structure. The sound insulation sleeve 2 is adapted to the anti-loosening pad 5. First, the sound insulation pipe 1 and the valve 4 are installed on the oxygen cabin through the installation sleeve 3. The threaded connection head 9 is threadedly connected to the threaded connection groove 7. The sound insulation sleeves 2 on both the inside and outside of the oxygen cabin are rotationally threadedly connected to the sound insulation pipe 1, so that the anti-loosening pad 5 is closely attached to the sound insulation sleeve 2. And the spherical cavity 12 is used to improve the deformation elasticity of the anti-loosening pad 5, enhance the extrusion force and friction force of the anti-slip groove 6, and prevent the loosening between the connectors from easily occurring after long-term use, which is beneficial to improving the installation stability of the decompression and sound insulation device and maintaining the sound insulation effect;

[0025] A dust-proof net 8 is fixedly installed at one end of the sound insulation sleeve 2. A threaded connection head 9 is arranged at the other end of the sound insulation sleeve 2. A partition 10 is fixedly installed inside the sound insulation sleeve 2.

The polyester fiber sound-absorbing board material and the sound-absorbing cotton material are used to expand the contact area between the air flow and sound waves and the sound-absorbing material, so that most of the sound wave energy is converted into mechanical energy or heat energy in the interaction force between the fibers and pores in the sound-absorbing structure, increasing the consumption of sound wave energy.
