description An elevator safety device utilizing air pressure is provided for protecting people from being hurt in the dropping process of an elevator, when other elevator safety devices all cease to be effective. The elevator safety device utilizes the air pressure brought by the high-speed dropping of the elevator at the last moment to support and make the elevator drop slowly, and forms a protective air cushion inside the elevator to protect the people inside the elevator from being hurt by the high-speed dropping of the elevator onto the earth. The elevator safety device provides an effective safety guarantee for broad masses.
