Description

Technical Field

[0001] The utility model relates to the technical field of door and window corners, in particular to an adjustable heat-insulating door and window corner. Background Art

[0002] Aluminum alloy door and window corners are used to connect two doors and windows set at an angle, which can fix the doors and windows and improve the sealing and aesthetics. Traditional adjustable angle door and window corners usually use arc-shaped corner plates, such as a universal door and window corner fixing structure disclosed in a Chinese patent with patent application number 202020023467.9. It is necessary to change the size of the arc surface of the arc-shaped corner plate to change the angle of the door and window corner, and the versatility of this structure is poor. In addition, the patent application number 202110852387.3 also discloses a size-adjustable multi-angle door and window corner frame structure. When used, the position of the limit member is determined by adjusting the non-return plug-in end of the connector to insert into the non-return groove, and then the resistance part of the resistance member is in contact with the side of the L-shaped member, and cooperates with the outer frame to limit the movement of the L-shaped member to determine the size of the clamping part. By adjusting the extension of the sliding part of the resistance member into the arc groove, the deflection angle of the sliding member is limited to determine the angle of the corner frame. Finally, the sliding part of the resistance member is locked by screws to complete the locking of the angled corner frame. The door and window corner frame structure has a complex structure, high installation and production costs, and traditional door and window corner structures take up more space, which is not conducive to storage and transportation.

[0003] In order to solve the above technical problems, the existing Chinese patent publication number is CN216690842U, which is an angle-adjustable door and window corner structure, which includes: a corner connector, whose end face adopts an angle structure formed by detachably connecting two corner fins, and the inner side of the end face is connected to a limit connector; two window outer frames are respectively connected to the two sides of the limit connector, and the angle between the two window outer frames is adjustable. The angle-adjustable door and window corner structure of the utility model is simple in structure, which is conducive to reducing installation and production costs, and the corner fins of the corner connector can be disassembled and installed as needed, which is convenient for replacing different corner fins, which is conducive to improving the versatility of the product, and after the corner fins are disassembled, it is conducive to reducing the space occupancy during storage and transportation.
