The utility model discloses a speed locking cantilever stick subtracts isolation bearing, including upper bracket board, intermediate lamella and bottom suspension bedplate, the upper end of intermediate lamella is connected in the first recess that upper bracket board downside formed, and the lower extreme of intermediate lamella is connected in the second recess that the undersetting plate -type becomes to multidirectional slip in the second recess, be provided with the cantilever stick between upper bracket board and the bottom suspension bedplate, bottom suspension bedplate below is provided with the sliding plate, is provided with the speed lock between sliding plate and the bottom suspension bedplate, the 3rd flat sliding plate is installed to the downside of bottom suspension bedplate, and the 3rd corrosion resistant plate is installed to the upside of sliding plate, and it is vice that the 3rd flat sliding plate and the 3rd corrosion resistant plate form the friction. The utility model discloses a speed locking cantilever stick subtracts isolation bearing has increased the speed lock, can be with normal displacement locking and unblock and the seamless combination of shock attenuation displacement. This support passes through the speed lock to the locking and the unblock of one -way displacement, realizes the effect of earthquake power level dispersion to each mound.
