Wind and rain automatic window closing device applicable to multiple window types with zero-power-consumption standby and convenience in mounting

Abstract

The invention relates to a wind and rain automatic window closing device applicable to multiple window types with zero-power-consumption standby and convenience in mounting. The wind and rain automatic window closing device disclosed by the invention adopts integrated design, requires no wiring and can be rapidly mounted on various push type windows and casement windows (doors) in different sizes. The wind and rain automatic window closing device has the functions of traction overload protection, casement touch alarm, window closing with snow water prevention and vertical rainfall prevention, and window opening on rainy days so as to exchange gas regularly. A control circuit is simple and reliable, and especially a zero-power-consumption standby design is adopted, so that the practical value of the wind and rain automatic window closing device disclosed by the invention is increased. The wind and rain automatic window closing device is formed by sequentially mounting and electrically connecting a pulling rope, a force measuring arm, an automatic winding device, an automatic clutch, a control circuit, a sensor switch and a direct current speed reduction motor in a shell, wherein the pulling rope is led out form the wheel of the force measuring arm at an opening at one side of the shell, a single pulling rope is used for pulling a casement when meeting wind and rain, and closing of a double-casement casement window or a single-casement push type window is completed. The wind and rain automatic window closing device disclosed by the invention is simple and convenient to mount, has wide application range and complete function, is the best solution for preventing wind and rain from invading for windows and doors of commercial and residential buildings and is applicable to mass production and popularization.

Description

technical field [0001] The invention relates to a device capable of automatically closing windows (doors) in case of wind and rain under specific conditions, especially suitable for quick installation on push-open and casement windows (doors) of various sizes. It is an integrated window closer with zero power consumption standby, traction overload protection, window sash trigger alarm, anti-snow water, anti-vertical rain window closing and rainy day window opening timing ventilation functions. Background technique [0002] At present, the known automatic window closing devices for finished products are mostly integrated in the finished windows with gears, gear rods and worms plus control parts by window manufacturers. Most of them are used in special occasions such as fire protection, high-end commercial and residential buildings, etc., and the cost is high. They cannot be installed and used in residential buildings and office buildings with different window types and sizes,...
