Set the solid aluminum reinforcing rib inside the mullion, and fix the reinforcing rib inside the mullion through mechanical connection to enhance the lateral support of the mullion and improve the overall structural stability of the window.
[0020] The installation of the opening fan accessory includes the following steps: 1. Installing the screen window hidden hinge (8): embed the screen window hidden hinge (8) in the pre-processed position of the screen fan frame. Use appropriate mechanical screws to firmly connect the hinge with the screen fan frame, ensuring that the hinge is flush with the screen fan frame after installation and does not affect the aesthetics. The hinge should also ensure smooth opening and closing of the screen fan, and the rotation flexibility of the hinge should meet the design requirements. 2. Installing the screen window lock point (9) and the screen window Y handle (10): install the screen window lock point (9) in the corresponding position of the screen fan frame, ensuring that the lock point is firmly installed and accurately positioned to precisely cooperate with the lock seat on the window frame. 3.
