Vibration isolation supporting structure and vibration isolator

The invention relates to the technical field of mechanical equipment, and provides a vibration isolation supporting structure and a vibration isolator. The vibration isolation supporting structure comprises a through connection end cover (1), at least two vibration isolation supporting units (2) and a through connection end cover (3). The at least two vibration isolation supporting units (2) are arranged between the through connection end cover (1) and the through connection end cover (3) in a manner of being sequentially connected in series. A cross-shaped supporting framework (21) and four evenly-distributed local area vibrators (22) are included in each vibration isolation supporting unit (2). The local area vibrators of the at least two vibration isolation supporting units (2) are periodically distributed in series connection so as to attenuate vibration energy transmitted to a supported object from a supporting foundation. The structure has the characteristic of periodic distribution in the supporting di
