Pressure safety device of elevator

Abstract

The invention discloses a pressure safety device of an elevator, which is a device which can protect people from being hurt after the elevator falls under the condition that other safety devices are out of work. By adoption of the pressure safety device, the elevator is supported by air pressure which is brought when the elevator falls at high speed at the last moment and slowly falls, and a protective air cushion can be formed in the elevator, so that a phenomenon that the people in the elevator are hurt because the elevator falls to the ground at high speed is avoided. Therefore, an effective safety control is provided for the masses.
