Abstract

This utility model discloses an aluminum alloy door and window drainage component, relating to the field of aluminum alloy door and window technology. Specifically, it includes a fixed part connected to the drainage hole of the aluminum alloy door and window, a connecting part connected to the fixed part, and a telescopic part connected to the connecting part. A filter frame is provided at the bottom of the connecting part. The telescopic part includes a lifting frame sleeved outside the filter frame. The lifting frame is connected to the connecting part by a spring. A filter ring is provided at the bottom of the inner cavity of the lifting frame, and guide plates are provided on both sides of the top of the inner cavity of the lifting frame. The top of the filter ring is located directly below the bottom of the two guide plates. This aluminum alloy door and window drainage component has a detachable structure; the connecting part can be quickly disassembled from the fixed part, and the telescopic part can be quickly assembled and disassembled from the fixed part, facilitating the installation and cleaning of the drainage component. By changing the drainage area and increasing the water storage space, the contradiction between insect prevention and drainage speed is balanced.
