Fireproof window capable of being automatically closed

Abstract

The invention provides a fireproof window capable of being automatically closed. The fireproof window 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 cylindrical shape memory alloy, a baffle, an elastic film and a spine part; the worm wheel is rotatably connected onto the window frame, and the worm is rotatably connected into the two first connecting plates; a circular notch is formed in the baffle, the edge of the elastic film is in sealed connection with thenotch, the edge of the baffle is in sealed connection with the side wall of an inner cavity of the shell, the inner cavity of the shell is divided into an upper cavity and a lower cavity, the upper cavity is filled with liquid, one end of the cylindrical shape memory alloy is fixedly connected with the bottom face of the lower cavity, and the other end of the cylindrical shape memory alloy is fixedly connected with the spine part; and the spine part is located under the elastic film, and when the cylindrical shape memory alloy is heated to extend, the spine part can pierce the elastic film. Bymeans of the fireproof window, the door and window can be automatically closed when a fire occurs, fire spreading is prevented, 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 that can be automatically closed. 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 that ca...
