drawstringwith built-in shutter insulating glass

technical field

The utility model relates to the technical field of doors and windows, in particular to a rope-pulling built-in louver insulating glass.

Background technique

Windows are an indispensable part of architecture. Windows undertake the functions of building lighting and ventilation. Windows in modern buildings are diverse and their functions are becoming more comprehensive and complex. For environmental protection, energy saving and comfortable living needs, sunshade products are widely used by people, and blinds are more common on indoor windows.

Built-in blinds are a kind of window with blinds arranged on the inside of the window, which have the functions of saving space, shading, heat preservation, and noise prevention, and have a novel structure. Insulating glass is widely used all over the world due to its unique characteristics of heat insulation, sound insulation, anti-condensation and anti-dust pollution, among which the most widely used are such as hollow glass windows, hollow curtain walls, hollow doors and so on. Built-in shading products such as blinds, organ curtains, etc. Insulating glass interior shutters are favored because they can better ensure privacy while shading, and have the advantages of beautiful appearance.

Among them, the insulating glass shutter includes a shutter, an insulating glass, a shutter lifting device, a shutter turning device and a window frame. The perimeter of the insulating glass is sealed in the window frame. Venetian blinds are arranged between the inner glass and the outer glass of the insulating glass. Specifically, the venetian blinds are connected from top to bottom by honeycomb blinds and venetian blinds, or two connection methods are connected from top to bottom by venetian blinds and honeycomb blinds. The louver turning device includes a traction device, a blade turning part and a transmission device. The traction device includes an inner handle arranged in the window frame, an outer handle arranged on the outer surface of the window frame, and the inner handle and the outer handle are correspondingly matched in position. Both the inner handle and the outer handle are provided with magnets, and the two are magnetically connected by the magnets. When the outer handle is pulled to move on a fixed track, the inner handle moves with the movement of the outer handle under the action of the magnetic force of the magnet.

In the traditional rope-pulling built-in louver insulating glass, the turning of the venetian blinds is realized by turning the rope. One end of the overturned traction rope is sleeved on the rotating shaft, and the other end is connected to the handle. In addition, the ladder rope is wound around the shaft and the venetian blinds. In this way, when the user pulls the handle, the rotating shaft is rotated, and the rotation of the rotating shaft can drive the venetian blind to turn over. However, the traditional rope-pulling built-in louver insulating glass has slack and insufficient tension in the overturning traction rope, which causes the user to pull the handle.
