The invention discloses a helicopter deck hanger bolt hole plugging structure. The structure comprises a plugging piece and a fixed piece, and the plugging piece comprises a plugging part penetratingthrough and being arranged in the hanger bolt hole, and a limit part clamped and arranged on an aluminum antiskid surface; the plugging part comprises a cylindrical section and a circular truncated cone, a top end of the cylindrical section is fixedly connected with a lower bottom surface of the limit part, diameter of the cylindrical section fits the diameter of the hanger bolt hole, and a bottomsurface of the limit part completely cover an upper top surface of the cylindrical section; a bottom end of the cylindrical section is fixedly connected with one end, having relatively bigger cross section, of the cylindrical section; the limit part, the cylindrical section and the circular truncated cone are coaxially arranged; the upper top surface of the limit part is provided with several fixed pieces to fix the plugging piece on the aluminum antiskid surface; and waterproof layers are respectively arranged in the hanger bolt hole, on the limit part and on a sidewall of the cylindrical section. The helicopter deck hanger bolt hole plugging structure provided by the invention can effectively plug the hanger bolt hole so as to prevent dirty oil and rainwater from entering into an orlopdeck, and thus, possibility of occurrence of safety accidents is reduced.
