In shape pedestal 2, tubular pedestal 2 and support rod are connected between 1 side by horizontal direction damping.
Described includes vertically rubber shock-absorbing ball 31 and damping spring 32 to damping；The both ends point of rubber shock-absorbing ball 31
It is not connected to 1 bottom end of 2 bottom surface of tubular pedestal and support rod, damping spring 32 is sheathed on outside rubber shock-absorbing ball 31 and damping spring 32
Both ends be connected to the side wall of 1 lower part of 2 bottom surface of tubular pedestal and support rod.
Damping spring 32 is connect with support rod, so damping spring 32 plays the role of support in itself, bears generator sheet
The most weight of body；Also therefore there is no the weight for bearing generator for rubber shock-absorbing ball 31 itself, by its material and structure
Characteristic, can preferably absorb generator generation it is vertical to vibration, while can also suitably absorb generator generation water
Put down to vibration.
The horizontal direction damping includes being sheathed on the rubber ring 41 of 1 periphery of support rod and being connected to outside support rod 1
The spring 42 supported above of three groups of side wall, the side wall surface of the periphery fitting and tubular pedestal 2 of the rubber ring 41, support spring 42
Outer end be connected to the side wall surface of tubular pedestal 2.
Rubber ring 41 and support spring 42 are located at two different levels, can preferably fix support rod, prevent from supporting
Bar is dislocated.Still further aspect rubber ring 41 and support spring 42 each provide different damping modes, can effectively inhale
Receipts horizontally shake.
The support spring 42 is distributed according to 1 axis circular array of support rod.
The friction-reducing structure for reducing frictional force between the two is additionally provided between rubber ring 41 and support rod 1.In order to keep away
Exempt from rubber ring 41 and support rod 1 causes the too fast loss of rubber ring 1, so increasing friction-reducing structure.
The friction-reducing structure can have following two embodiment
Embodiment 1:
The friction-reducing structure is the Flocked fabric 51 that 41 inner ring of rubber ring is arranged in as shown in Figure 1:, flocking in Flocked fabric 51
