The expansion layer 12 is located between the sandwiching space 100 and the damping layer 11, and the expansion layer 12 has an inner circumferential surface 121 facing the sandwiching space 100, and the inner circumferential surface 121 is a circumferential surface, so that the sandwiching space 100 has a circular cross-sectional profile in the axial direction. The damping layer 11 is provided with a first fracture 110 at a circumferential position, the expansion layer 12 is provided with a second fracture 120 at an axial position, the first fracture 110 is communicated to the position, farthest away from the clamping space 100, on the periphery of the damping ring, and the first fracture 110, the second fracture 120 and the clamping space 100 are communicated in the radial direction of the damping ring.

The damping layer 11 is made of a soft rubber material or a silicone material, and the expansion layer 12 is made of a soft rubber material having thermal expansibility, a soft plastic material, or a foam material having thermal expansibility and elastic deformability, such as polyethylene.

The air conditioner provided by the invention comprises an air conditioner outdoor unit, wherein a compressor assembly is arranged in the air conditioner outdoor unit, the compressor assembly comprises a compressor (not shown in the figure), a vibration reduction ring and a binding belt 13, the compressor comprises a machine body and a pipe body 9 led out of the machine body, the pipe body 9 sequentially passes through a first fracture 110 and a second fracture 120 and then enters a clamping space and is kept in a state of passing through the clamping space 100, and the inner circumferential surface 121 of an expansion layer 12 is abutted against the outer circumferential surface of the pipe body 9.

The binding belt 13 is bound on the periphery of the damping ring to provide a pretightening force between the inner peripheral surface 121 of the expansion layer 12 and the outer peripheral surface of the tube body 9, and meanwhile, the binding belt 13 is bound on the periphery of the damping ring to prevent the damping ring from deforming due to external expansion caused by heating. Assuming that the total weight m of the damping rings is 40g, in order to ensure the anti-loosening effect of the damping rings, the friction force fmin between the inner circumferential surface 121 of the expansion layer 12 and the outer circumferential surface of the pipe body 9 in the compressor operating state should be in accordance with: fmol > 5mg, i.e. fmol should be greater than 2N; the maximum static friction factor between the inner surface of the expandable layer 12 and the outer surface of the tubular body 9 is measured experimentally to be between 0.25 and 04, where the limit is 0.25, so that the interaction force F between the expandable layer 12 and the tubular body 9 is always F moles/0.25N.
