▎ 摘　　要

NOVELTY - Aluminum alloy profile comprises a movable connecting plate (2) set at two sides of an aluminum alloy base body (1). A connecting part of the aluminum alloy base body and the movable connecting plate is provided with a connecting round groove (3), a connecting round head (5) and a connecting groove (10). An inner part of the aluminum alloy base body is provided with a heat insulation noise reduction cavity. A connecting part of the aluminum alloy base body and the heat insulation noise reduction cavity is provided with a connection slide strip. Two sides of the heat insulation noise reduction cavity of the aluminum alloy base body are respectively provided with a concave cavity and a square cavity. Two sides of the aluminum alloy base body are provided with multiple irregularly shaped edge grooves. An inner part of the heat insulation noise reduction cavity is filled with honeycomb-type heat insulation noise reduction layer whose outer part is covered with heat insulation resin layer. USE - The profile is useful for energy-saving and environment-friendly door and window. ADVANTAGE - The profile improves heat insulation, noise reduction and high-temperature resistant effect of aluminum alloy door and window, improves structure of aluminum alloy door and window frame, and improves multifunctional effect of aluminum alloy, so that the aluminum alloy door and window has good market potential value and application prospect, and practicability and creativity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of aluminum alloy profile for energy-saving and environment-friendly door and window. Aluminum alloy base body (1) Movable connecting plate (2) Connecting round groove (3) Connecting round head (5) Connecting groove (6)
