Description

Frame structure of aluminum profile window sash

Technical Field

The utility model relates to a door and window field, especially an aluminium alloy casement frame structure.

Background

At present, many window sashes adopt aluminum profile frames. In order to facilitate the installation of glass, a glass pressing strip profile is generally installed on the aluminum profile frame. In order to realize the installation of the glass bead section bar, a clamping groove for clamping the glass bead section bar is formed in the frame of the aluminum section bar. Wherein the glass bead section bar is tightly clamped in the clamping groove. When the glass is damaged, the outer wall of the glass bead profile is extruded to elastically deform the glass bead profile, so that the glass bead profile can be separated from the clamping groove. Because the existing glass bead sectional material is thin in wall thickness, deformation which is difficult to recover or fracture is easy to occur in the process of extruding the glass bead sectional material, so that people have to buy a new glass bead sectional material, and the use cost of people is easy to increase. Because the glass bead section bar is of a strip-shaped structure, the extrusion is not very convenient, so the convenience for disassembling the glass bead section bar is poorer, and the replacement efficiency of the glass is easily reduced.
