Abstract

The invention relates to a fast escape lock comprising a slant bolt component and a square bolt component, wherein the square bolt component is controlled to be retracted and extended out by a turn button in the square bolt component, and the slant bolt and the square bolt are controlled to be retracted by a handle in the slant bolt component; the fast escape lock also comprises a rear through piece, a sliding plate and a toggling piece for the turn button, wherein the rear through piece is interlocked with the handle to be rotated, and two axial bulged shifting blocks are arranged at the outer brim and are clipped on the sliding plate; the sliding plate is an oblong thin sheet, both ends are respectively provided with bend angles which are tucked up, and the shifting blocks of the rear through piece are clipped on the bend angle of one end of the sliding plate; the toggling piece for the turn button is interlocked with the turn button to be rotated, and the outer brim is provided with an oblique angle coming in contact with the bend angle of the other end of the sliding plate; and the handle is rotated to drive the rear through piece to pull the sliding plate, and the toggling piece for the turn button is driven to rotate by the sliding plate so as to retract the square bolt. The fast escape lock provided with the considerably simple components realizes the interlock of the handle, and by rotating the handle in a door, the square bolt and the slant bolt can be retracted at the same time, thus people can fast escape at a critical moment.
