Folding hinge device for electric smoke exhaust opening window

Abstract

The invention discloses a folding hinge device for an electric smoke exhaust opening window. The folding hinge device comprises a hinge upper piece, a hinge lower piece and a hinge rotating shaft, wherein the hinge upper piece and the hinge lower piece are both provided with two vertical bending sections; a fixing frame of the smoke exhaust window is fixedly connected to the top surface of the hinge upper piece, and an opening sash is fixedly connected to the bottom surface of the hinge lower piece; horizontal plates below the hinge upper piece and the lower piece are both provided with a plurality of screw holes; and the fixing frame of the smoke exhaust window is fixedly connected with the opening sash through screws in the screw holes. Aiming at the defects in the prior art, the foldinghinge device for the electric smoke exhaust opening window is reasonable in design, simple in structure and safe and reliable, and can effectively increase the opening angle of hinges so as to meet the opening requirement of fire fighting.

Description

technical field [0001] The invention relates to a hinge device, in particular to an electric smoke exhaust opening window folding hinge device. Background technique [0002] Today's buildings need ventilation and smoke extraction, but most of the existing smoke exhaust skylights are open-air, and they often have problems of blockage or air leakage during use, especially in rainy weather, and even rainwater leakage Therefore, this will not only block the smoke exhaust pipe, but also cause damage to the interior of the house, and even cause smoke and dust to be sucked back, seriously affecting the smoke exhaust effect of the building. According to the requirements of the construction regulations, a smoke exhaust system must be installed in the building to discharge the smoke in the building in time during the daily ventilation and in the event of a fire, so that the evacuated personnel and disaster relief personnel will not be trapped by the smoke and fire, reducing casualties...

AI Technical Summary

Problems solved by technology

According to the specific requirements of the smoke exhaust volume, the opening angle of the general fire smoke exhaust electric opening window is not less than 70°, and the ordinary electric opening window needs to use the sliding stay hinge as the opening angle control device, but the setting of the device can only make the electric opening The opening angle of the window reaches 30° or the opening distance is less than 800mm. This angle or opening distance is far from meeting the requirements of fire and smoke exhaust, and the cost of accessories is high

Traditional smoke exhaust windows are generally opened in the form of hinges, but special profiles are required for window profiles. The actual finished effect is not beautiful, the opening effect is poor, and the facade has a greater impact
