There is gap between part and the vertical rubber support horizontal direction of thick meat type, the horizontal rubber block and the second steel part are in close contact.
Further, the vertical rubber support of the thick meat type includes thick meat type rubber and steel plate, and the thickness meat type rubber is put
If between dried layer steel plate, and it is integral with steel plate vulcanization.
Further, the centre of the vertical rubber support of the thick meat type is provided with through hole.
Further, the vertical cross-section wedgewise of the horizontal rubber block.
Further, the inner cavity of second steel part is equipped with inclination angle, is engaged with the wedge-type shape of horizontal rubber block.
Further, the vertical rubber support of the thick meat type is cylinder, and two steel parts is circular, the horizontal rubber block
For ring-type.
Further, the vertical rubber support of the thick meat type is cylinder, and two steel parts is circular, the horizontal rubber block
To be segmented ring-type, there is the gap of disconnection in centre.
Further, the thick vertical rubber support of meat type is cuboid, and two steel parts are rectangle, the horizontal rubber
Block is cuboid, totally two pieces, front and rear to be arranged at the first steel part both sides.
Compared with prior art, the present invention has the advantages that substantive distinguishing features of following protrusion and notable：
Isolation mounting of the present invention can be used in subway floating plate system, common by horizontal rubber block and the vertical rubber support of thick meat type
Realize the function of isolation Subway Vibration.Apparatus structure good reliability, long term life is good, and can realize production domesticization, and low cost, has
Wide application prospect.
