Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy door and window processing, in particular to a rotatable universal corner of an aluminum alloy door and window. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy door and window extrusion profiles as frames, stiles and sashes. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include doors and windows with aluminum alloy doors and windows as the load-bearing rod base material and doors and windows composited with wood and plastic, or aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows for short. Existing aluminum alloy doors and windows are mainly composed of three parts: window frame profiles, glass and movable components. The movable components include hinges, handles and pulleys, etc. The window frame profiles generally need to adopt the corner structure of casement windows. The corner structure can be used to achieve the installation of two plane window frames at a certain angle, so that the window area can be increased and sufficient lighting space can be obtained.

[0003] And in the document with publication number CN219471937U, a rotatable universal corner of aluminum alloy doors and windows is mentioned. When the angle of the corner needs to be adjusted, that is, the protruding length of the corner fixing seat relative to the corner baffle needs to be adjusted, the connecting plate is manually pulled upward, and the connecting plate drives the moving block to rise through the moving rod. During the rising process of the moving block, the tension spring is compressed. The tension spring accumulates elastic potential energy during the compression process, and then moves the corner fixing seat. During the movement, the movement stability is improved by the cooperation of the rotating shaft and the roller. When the corner fixing seat moves to a suitable position, the connecting plate is loosened, and the tension spring releases its elasticity to drive the moving block to descend, and then the limiting steel bar at the bottom of the connecting plate is driven by the moving block to insert into the limiting groove, so that the position of the corner fixing seat is limited and fixed. The overall adjustment method is simple and convenient, and it is highly practical.

[0004] At the same time, the document with publication number CN217054891U mentions a universal corner with wide applicability for aluminum alloy doors and windows, in which the main insulating profile of the corner and the indoor auxiliary profile are connected together by rotating through a rotating device. Specifically, the rotating column is inserted into the rotating groove to connect the main insulating profile of the corner and the indoor auxiliary profile, and then the indoor door and window frame and the outdoor door and window frame are connected together through the first connecting rib, and then the first outdoor auxiliary profile is connected and fixed to the outdoor door and window frame through short self-tapping screws, and then the long self-tapping screws are passed through the mounting hole, and the indoor door and window frame is connected and fixed to the indoor auxiliary profile through the long self-tapping screws, and the angle between the indoor auxiliary profiles on both sides is adjusted by the rotating device according to actual conditions. After the adjustment is completed, the long self-tapping screws are continued to be driven in clockwise to make the long self-tapping screws drive into the inner cavity of the main insulating profile of the corner to fix the angle between the indoor auxiliary profiles on both sides, and then The doors and windows are then connected to the corner. Compared with the prior art, this solution can be achieved during the installation of aluminum alloy doors and windows by fixing the indoor auxiliary profile and the indoor door and window frame into one with long self-tapping screws, and the first outdoor auxiliary profile and the outdoor door and window frame are fixed into one with short self-tapping screws. A rotating device is set on the indoor surface of the corner main insulation profile and rotates with the indoor auxiliary profile, so that the angle of the doors and windows on both sides of the corner can be adjusted, which can meet the turning angle of any angle of the doors and windows, and can adapt to the installation of a variety of aluminum alloy doors and windows, reducing the cost of installing aluminum alloy doors and windows, and improving the sealing and aesthetics of aluminum alloy doors and windows after installation. However, there are still certain defects that need to be optimized. The specific defects are as follows: The method of fixing the corner fixing seat by controlling the position of the limiting steel bar by a tension spring is unstable. At the same time, the fixing force of the self-tapping screws needs to be improved when the angle is fixed by only using self-tapping screws.

[0005] Therefore, it is particularly important to design a rotatable universal corner of aluminum alloy doors and windows to change the above-mentioned technical defects and improve overall practicality. Utility Model Content
