Background

The screen window is divided into an invisible screen window and a non-invisible screen window, and the invisible screen window is widely applied because the screen window hinge connecting the screen window sash and the window frame is hidden at the joint of the screen window sash and the window frame when the invisible screen window is closed, so that the invisible screen window looks more beautiful outside. The screen window hinge is generally installed at a corner of a window frame, so that an aluminum profile window frame is widely applied, and an installation clamping groove is reserved at a corresponding part of the window frame to serve as a screen window hinge fixing part. The screen window hinge is specially used for controlling the opening and closing of the screen window sash and the window frame, and an opening and closing angle is formed between the screen window sash and the window frame in a general opening state.

At present, a plurality of screen windows are installed in a hidden mode, namely the screen windows are opened indoors, and a hidden screen window sliding support hinge on the market at present generally comprises a frame fixing piece, a supporting arm and a connecting rod mechanism for connecting the frame fixing piece and the supporting arm, wherein the supporting arm is used for installing a window sash, the frame fixing piece is used for fixing the window frame, the connecting rod mechanism generally comprises a short rod, a long rod and a plurality of supporting pieces, and the connecting rod mechanism is used for better bearing, and the rods are connected in a crossed mode or crossed mode; or a plurality of rod pieces are connected, the load is dispersed, the connection is complicated, and the manufacturing cost is high. In addition, because the stress is mainly distributed on the short rod, the short rod is just like a seesaw, the suspended end of the short rod is pressed, the short rod is pulled only through a hinge point (for example, the short rod is rotationally connected through a rivet) rotationally connected with the frame fixing piece, the stress is too concentrated, the short rod and the rivet connected with the frame fixing piece are easy to wear, and the service life is short.

In order to solve the above problem, chinese utility model patent 201922008811.7 "a hide and provide a hidden screen window hinge in the screen window hinge", cooperation through C type groove, in the unsettled one end of quarter butt when pressurized, at the opposite side of point of lifting, except that the rotation hookup point department of quarter butt and frame stationary blade provides a decurrent power of quarter butt, still provide a decurrent power of quarter butt through the last cell wall in C type groove, thereby alleviate the rotation hookup structure's of quarter butt and frame stationary blade rotation hookup point department atress, the atress of balanced each component, improve holistic structural strength, increase the resistance to deformation ability of quarter butt, improve the quality and the life of product. However, since the short bar and the frame fixing plate still adopt a single-sided hinge manner, most of the force is concentrated on a single side of the frame fixing plate, and the effect of enhancing the structural stability is still limited.
