Double-arm window winder

Abstract

The invention relates to a double-arm window winder relating to a window sill, a window frame and a window sash. The window frame is mounted on the window sill, and one side of the window sash is connected with the window frame. The double-arm window winder is characterized in that: the double-arm window winder comprises a window winder main body, a window sash upper-part push-pull mechanism, a window sash lower-part push-pull mechanism and a double-arm associated push-pull device; the window winder main body is fixed on the window sill, the window sash upper-part push-pull mechanism is arranged at the upper end of the window frame, and the window sash lower-part push-pull mechanism is arranged at the lower end of the window frame; the window sash upper-part push-pull mechanism and the window sash lower-part push-pull mechanism are in contact with the window sash, two ends of the double-arm associated push-pull device are connected with the window sash, and the other two ends of the double-arm associated push-pull device are connected into the window winder main body. Therefore, the opening and closing of the window sash are more convenient due to the matching among the window winder main body, the window sash upper-part push-pull mechanism, the window sash lower-part push-pull mechanism and an angle ruler fixing plate; moreover, as a double-arm structure (a main push-pull arm and an auxiliary push-pull arm are matched with each other) is adopted, the heavy window sashes can also be easily pushed or furled.

Description

technical field [0001] The invention relates to an opening and closing device for a window sash, in particular to a double-arm window swinging device. Background technique [0002] As far as the existing construction field is concerned, the opening or closing of the window sashes used in most buildings needs to be done manually by the user. Moreover, the arm should be stretched out of the window during operation. Sometimes due to the weight of the sash itself or the tightness of the connection, it takes a lot of effort to open or close the sash, which is inconvenient in operation. At the same time, during the opening or closing of the sash, unnecessary collisions between the sash and the window frame often occur. Contents of the invention [0003] The object of the present invention is to overcome the above problems in the prior art and provide a dual-arm window device. [0004] In order to realize the purpose of the present invention, the dual-arm window device relates ...
