Description

TECHNICAL FIELD

[0001] The utility model relates to door and window technical field, concretely relates to a folding screen door and window screen. BACKGROUND

[0002] The screen door or screen window prevents small animals such as insects from entering the room through the screen, and it is mainly divided into two categories: one is the fixed frame screen door or screen window, and the other is the folding screen door or screen window. The screen in the folding screen door or screen window is a flexible net structure, which needs to use nylon rope to fix the screen window net body, and also needs to use nylon rope to pull during pushing and pulling. However, the service life of the nylon rope is short, and it is easy to age and break after a period of time, so the service life is short; the screen surface is easy to get dirty and difficult to clean.

[0003] The patent document with the application number CN201320367682.0 discloses a telescopic screen window body, which comprises a window frame and a telescopic screen window box arranged on the window frame.
