[0002] Protective railings refer to the addition of a protective mesh layer to the existing windows of a building. In modern cities, most residential buildings are mid- to high-rise buildings. Since the window openings of mid- to high-rise buildings are in a state of open space, if there are children in the home, protective railings are usually installed at the window openings to ensure the safety of the children and prevent accidental falls.

[0003] In modern construction, more and more buildings are using aluminum alloy doors and windows, and guardrails have become a safety barrier between the interior and exterior. Most existing guardrails are independent systems made of steel or aluminum and are fixed between the window sash and screen sash of the door and window system. A lot of screws are needed to fix the guardrails. This installation method makes the installation and disassembly of guardrails quite troublesome. When guardrails are no longer needed or need to be replaced, installers cannot properly disassemble and install them. Utility Model Content
