Anti-theft escape window

Abstract

The invention discloses an anti-theft escape window. The anti-theft escape window comprises an outer frame body, a window body and at least one locking device, wherein the lower end of the window bodyis hinged with the upper end surface of a cross rod at the lower end of the outer frame body; the locking device comprises a U-shaped plate, a ratchet wheel and a steel wire rope, wherein the U-shaped plate is fixedly arranged on the outer frame body, a first rotating shaft is arranged in the U-shaped plate, and both the two ends of the first rotating shaft penetrate through two side walls of theU-shaped plate; the ratchet wheel is coaxially arranged at one end part of the first rotating shaft, one side wall of the U-shaped plate close to the ratchet wheel is provided with a hinge pin, and the hinge pin is rotationally connected with a pawl matched with the ratchet wheel; and one end of the steel wire rope is connected to the window body, and the other end of the steel wire rope penetrates through the outer frame body and is wound on the periphery of the first rotating shaft. The anti-theft escape window disclosed by the invention has the advantages that by hinging the window body tothe outer frame body, when a fire occurs, the window body is rotated for 90 degrees, the locking device plays a fastening role under the action of the ratchet wheel and the pawl, and then, people canstand on the window body and wait for rescue, thereby achieving the escape action.

Description

technical field [0001] The invention relates to the technical field of anti-theft windows, more specifically, the invention relates to an anti-theft escape window. Background technique [0002] Existing window anti-theft products can be roughly divided into two categories, one is soft (non-entity) protection products, such as infrared anti-theft systems; the other is hard (entity) protection products, such as sliding grille windows, safety shutters Windows, anti-theft nets and anti-theft steel cage nets, etc. The anti-theft nets are composed of aluminum alloy or steel grids and frames, and the anti-theft steel cage nets are usually welded into cage nets by steel bars and angle steel. The former is more expensive, while the latter A kind of cheaper but mostly non-openable anti-theft products, non-openable steel cage nets and anti-theft windows have serious fire safety hidden dangers in real life. And the existing anti-theft window does not have the effect of being convenient...
