Adjustable anti-seismic support

The adjustable anti-seismic support comprises a bottom plate, side plates are perpendicularly fixed to the upper end face of the bottom plate, the side plates are distributed in a bilateral symmetry mode about the center line of the bottom plate, and threaded rods are connected into the side plates through bearings; the mounting frame is arranged right above the bottom plate and arranged between the two sets of side plates, rotatable limiting plates are symmetrically connected to the left side and the right side of the upper end face of the mounting frame through columnar shafts, meanwhile, a spring shock absorber is further fixed to the upper end face of the mounting frame, and a first clamping plate is fixed to the upper end of the spring shock absorber. According to the adjustable anti-seismic support, the fixing mechanism capable of being rotationally adjusted is adopted, the use requirements of pipeline installation of different modes can be met, the height adjusting mechanism is matched, the fixing requ
