This utility model discloses an umbrella-shaped ring structure for fixing an elastic pad on the lower cavity surface of a top cover. The structure comprises: a rubber elastic pad (1) completely covering the lower cavity surface of the top cover; an umbrella-shaped steel structure fixing ring (2) below the elastic pad (1), the fixing ring (2) consisting of a concentric circular skeleton and a radial skeleton, forming a support frame that divides the elastic pad (1) into multiple fan-shaped ring structures; and embedded bolts (3) evenly distributed around the fixing ring (2). The bolts (3) press and fix the elastic pad (1) to the lower cavity surface of the top cover (7) using pre-tightening force. Through the combination of the umbrella-shaped fixing ring and the embedded bolts, both fixing the elastic pad and utilizing the pad's damping and vibration reduction function are achieved, thereby effectively reducing abnormal vibrations of the top cover.
