The invention relates to a quick replacement mechanism, in particular to a quick spring replacement mechanism for an equipment damping device. The quick spring replacement mechanism for the equipmentdamping device comprises a sliding frame assembly, a spring installation sleeve assembly and a top cover. A spring in the equipment damping device is used for damping and can be disassembled and replaced rapidly so that different springs can be installed in the equipment damping device to achieve different damping effects. The sliding frame assembly comprises a fixed plate, sliding rail rods, a sliding base, a round insertion rod, a hinge base connecting rod and a U-shaped hinge base. The hinge base connecting rod is fixedly connected to the middle of the upper end of the fixed plate. The U-shaped hinge base is fixedly connected to the upper end of the hinge base connecting rod. The sliding rail rods are fixedly connected to the left end and the right end of the fixed plate. The sliding base is slidably connected to the front ends of the two sliding rail rods. The round insertion rod is fixedly connected to the middle of the upper end of the sliding base.
