[0007] Furthermore, in order to better realize the utility model, the fan fixing plate is provided with three adjustable screws, the fan fixing block A is connected to the fan fixing plate through a transverse adjustment screw, the vertical adjustment screw and the transverse adjustment screw are both on the fan fixing plate, and the sealing adjustment screw can be adjusted in the adjustment slot of the fan fixing plate. This three-dimensional adjustment method improves the performance of the lower hinge component.

[0008] Furthermore, in order to better realize the utility model, the main board and the frame fixing plate are connected by rivets, and the rivets can slide in the slide groove, and the conversion gasket is installed, and the lower hinge part is rotated 90°. The conversion gasket is removed, and the lower hinge part is rotated 180°. It can be converted according to the requirements of different scenarios.

[0009] Furthermore, in order to better realize the utility model, the sash fixing block B and the sash fixing plate are assembled together by riveting, and the sash fixing block B can slide in the groove of the sash fixing plate, so that when the lateral adjustment screw is adjusted, the window sash can be adjusted left and right.

[0010] The beneficial effects of the utility model are:

[0011] The three-dimensional adjustment modes of the utility model are all on the sash fixing plate, which is convenient to adjust and can realize the conversion of the opening mode of the window sash to 90° or 180°. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] Figure 1-Figure 4This is a specific embodiment of the utility model, which is a 90° / 180° conversion hinge for plastic steel windows. The main board 6 and the sub-board 5 are riveted together, the pad 9 is riveted and fixed to the main board 6, the main board 6 and the sub-board 5 are riveted to the frame fixing plate 7 using rivets, the fan fixing block A 1 is connected to the fan fixing plate 12 through a lateral adjustment screw 14, the fan fixing block B 3 is connected to the fan fixing plate 12 through riveting, and the fan fixing block B 3 can slide in the groove 2. If the conversion gasket 16 is installed, the conversion gasket 16 limits the range of movement of the rivet to achieve 90° opening of the window sash. If the conversion gasket 16 is not installed, the window sash can be opened 180°. There are three adjustable screws on the sash fixing plate 12. After the window sash is installed, the three-dimensional adjustable function can be achieved by adjusting the three adjusting screws on the sash fixing plate 12. The dome column 10 below the sash fixing plate 12 is connected to the sealing adjustment screw 8. The dome column 10 is installed on the pad 9. The vertical adjustment screw 13 and the horizontal adjustment screw 14 are installed on the sash fixing plate 12.
