Fireproof window

Abstract

The invention provides a fireproof window which comprises a window frame, a window sash, a pulley, a pull rope, a worm wheel, a worm, first connecting plates, a transverse plate, a connecting rod, a shell, a limiting stop block, a bimetallic strip, a second connecting plate, a baffle, a first elastic film and a spine part. The worm wheel is rotatably connected to the window frame, and the worm isrotatably connected into the two first connecting plates; a first circular notch is formed in the baffle, the edge of the first elastic film is connected with the first circular notch in a sealed manner, the edge of the baffle is connected with the side wall of an inner cavity of the shell in a sealed manner, the inner cavity of the shell is divided into an upper cavity and a lower cavity, the upper cavity is filled with liquid, and one end of the second connecting plate is fixedly connected with the bottom face of the lower cavity; and the spine part is fixedly connected with the bimetallic strip and located under the first elastic film, and when the bimetallic strip is deformed and bent, the spine part can pierce the first elastic film. According to the fireproof window, the door and window can be automatically closed when a fire occurs, fire spreading is prevented, and the fireproof window is simple in overall structure and lower in cost.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a fireproof window. Background technique [0002] The fireproof window is a door and window product used to prevent the indoor fire from spreading outward. The traditional fireproof window generally needs to be closed manually to achieve fire prevention. Does not automatically shut itself off when a fire is detected. [0003] In order to solve the problem that traditional fireproof windows cannot automatically close when a fire is detected, intelligent doors and windows have appeared on the market, which use automatic detection and control systems to close the sash when a fire occurs, but the cost of such intelligent doors and windows is relatively high . Contents of the invention [0004] In order to overcome the problem of high cost of existing intelligent doors and windows, the present invention provides a fireproof window, the specific technical solution is as f...
