The invention provides an aluminum alloy in-opening window. An in-opening fan and a mullion are arranged in an edge frame. In-opening fan glass is arranged on an in-opening fan frame through an in-opening fan pressing line. A fixed fan is arranged between the mullion and the edge frame. The fixed fan comprises a fixed fan pressing line and fixed fan glass. The fixed fan glass is arranged on the mullion and the edge frame through the fixed fan pressing line. The in-opening fan glass is of a three-layer glass structure. An edge frame heat insulating bridge, an in-opening fan frame heat insulating bridge and a mullion heat insulating bridge are all located between inner side glass and outer side glass of the in-opening fan glass to form an isothermal layer. The edge frame and the mullion areeach provided with an equal-pressure adhesive strip. Each equal-pressure adhesive strip comprises a body and a contact lip edge. The body is internally provided with a cavity. A first groove and a second groove are correspondingly formed in the two sides of the body, wherein the first groove and the second groove are connected with the edge fame or the mullion. According to the aluminum alloy in-opening window, the heat insulation preservation performance and the sealing performance of the aluminum alloy in-opening window are improved, materials are saved, profiles are high in generality, andinstalling and using are convenient.
