Aluminum-plastic co-extrusion corner connector filling diversion trench opening structure

Abstract

The invention discloses an aluminum-plastic co-extrusion corner connector filling diversion trench opening structure. The aluminum-plastic co-extrusion corner connector filling diversion trench opening structure comprises an L-shaped connecting block, a first through hole and a first positioning block, a first connecting piece is arranged at the upper end of the L-shaped connecting block, and a second connecting piece is arranged on one side of the L-shaped connecting block. The aluminum-plastic co-extrusion corner connector filling diversion trench opening structure has the beneficial effects that by arranging the first through hole, a second through hole, a first connecting groove, a second connecting groove, a first T-shaped groove and a second T-shaped groove, the corner combining glue filling speed can be higher and more uniform, the filling time is shortened, and the using effect is improved; by arranging a heat preservation layer, the heat preservation performance of the structure can be improved, so that the adhesiveness of the corner combining glue is guaranteed, an aluminum lining and plastic are attached more tightly, and the connection strength of door and window is improved; and by arranging a first positioning block, a second positioning block and a positioning column, the first positioning block can position and support the first connecting piece, the second positioning block can position and support the second connecting piece, the positioning column can enable the L-shaped connecting block to be attached to the aluminum lining more tightly, so that the stability of connection between the structure and the door and window is improved, and practicability is good.

Description

technical field [0001] The invention relates to the technical field of aluminum-plastic co-extrusion door and window processing, in particular to an aluminum-plastic co-extrusion corner code filling and diversion groove structure. Background technique [0002] Aluminum-plastic co-extruded doors and windows: As the name suggests, aluminum-plastic co-extruded doors and windows are composite doors and windows in which aluminum lining and plastic are closely combined. , to achieve the integration of inner metal and outer plastic, so the doors and windows integrate traditional metal doors and windows and plastic doors and windows, and are compatible with the high strength of metal doors and windows and the thermal insulation advantages of plastic doors and windows. The appearance of aluminum-plastic co-extrusion doors and windows is A major change in the history of doors and windows. As a new generation of building energy-saving doors and windows, it will inevitably occupy a very...

Problems solved by technology

[0003] During the use of the existing aluminum-plastic co-extruded corner codes to fill and open the diversion channel structure, the flow rate of the corner glue is low, and the aluminum-plastic co-extruded doors and windows cannot be filled quickly, which takes a long time and reduces the use effect. Secondly, the existing The aluminum-plastic co-extrusion corner code fills the diversion groove structure during use, and the thermal insulation performance is poor. During the filling process, it is easy to reduce the temperature of the corner glue, thereby reducing the adhesion of the corner glue, so that the aluminum lining and the plastic The fit is not tight, which reduces the connection strength of doors and windows. In addition, the existing aluminum-plastic co-extruded corner brackets can not be quickly positioned during use, which makes the corner brackets prone to tilt during installation, thus It leads to uneven filling of the group corner glue, resulting in waste of resources and low practicability
