There are grooves on the surface, and the fixing parts of the left and right hinge components are respectively set in the corresponding grooves and fixed by screws. The transfer part is located on the inner side of the top plate. When the window sash is closed, The hinge components on both sides are folded in half to form a U shape, and when the sash is opened, the hinge components on both sides form an acute or right angle with the rotating shaft as the origin.

A further technical solution is that the top plate is formed by extending the outer side plate of the window sash, and extends close to the edge of the window frame, leaving only opening slits to form a shield for the installation chamber.

Another technical solution is that the opening of the installation chamber is provided with a water-repelling sealing strip, one side of which is set in the slot of the side frame of the window frame, and the other side is against the side frame of the window sash. .

In the above technical solution, the transition part is composed of several sections of hollow tubes cross-spliced, and two adjacent hollow tubes are respectively located on the window frame and sash, and the rotating shaft runs through the hollow tubes.

A further technical solution is that the rotating shaft is composed of a shaft in the middle and hexagon socket pins at both ends.

Due to the application of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art:

1. In the utility model, the hinge mechanism is located inside the window sash. The hinge assembly realizes the concealment of the hinge mechanism through the split and folding opening methods. On the one hand, it does not affect the aesthetics of the window sash on the other hand. The opening angle of the window sash can reach 90 degrees, and the indoor light effect is better;

2. The hinge components in the hinge mechanism are composed of a fixed part, a rotating connection part and an adapter part. They have the same profile section and are formed by a single mold to reduce costs;

3. The utility model has a simple structure and is easy to install.
