Preferably, compressing member further includes gasket 9, and the pad of gasket 9 is located between 8 and first damping block 3 of nut.The gasket 9 can
To increase the contact area of compressing member and the first damping block 3, so as to increase the compression stress surface of the first damping block 3, first is avoided
Damping block 3 causes local pressure is excessive to cause to damage since forced area is too small.Gasket 9 can be rigid member or elasticity
Part, it is therefore preferable to metalwork.
Preferably, gasket 9 is spring steel, can further absorb the upward effect of vibration of compressor, damping vibration load.
Preferably, the angle of inclination of the second damping block 4 is 25 to 45 degree, can be to avoid the angle of inclination of the second damping block 4
Horizontal direction component caused by too small is too small, the problem of can not effectively weakening the vibrational energy suffered by compressor mounting bracket,
On the other hand horizontal direction component is excessive caused by the angle of inclination of the second damping block 4 can also be avoided excessive so that second
The distribution of force of damping block 4 does not meet the design feature of the second damping block 4, causes the vibration ability to bear of the second damping block 4 to drop
The problem of low.
