Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a sawn folding screen door and window. Background Art

[0002] Screens are installed on doors and windows to achieve ventilation between the inside and outside of the house. At the same time, they can prevent foreign objects (mosquitoes, catkins, etc.) from entering the room, and can improve safety, such as preventing children from climbing and falling, and objects from falling from high places.

[0003] In a sliding window, the screen is mounted on a sliding rail on the main body of the window frame and slides on the rail to move the screen to the ventilation position of the sliding window. Existing folding screen doors and windows have plastic parts of different sizes, which need to be processed separately during the production process and then assembled together, which is cumbersome and complex to install.
