Description

Corner double-knife corner connector for aluminum alloy door and window

Technical Field

The utility model belongs to the technical field of door and window's technique and specifically relates to an aluminum alloy door and window corner double knives angle sign indicating number.

Background

With the continuous progress of society, the door and window industry has been rapidly developed. In the window and door industry, aluminum alloy windows and doors are important components. At present, corners of aluminum alloy doors and windows are mostly inserted and fixed by adopting single-knife corner connectors, so that the connection of the corners can be guaranteed; however, in the long-term use process, the single-blade corner brace is often shaken in different directions after being fixed, the fixing effect is poor, the whole aluminum alloy door and window has great potential safety hazards in use, and great inconvenience is brought to the actual practice of people.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: in order to solve the problem that exists among the above-mentioned background art, the utility model provides an aluminum alloy door and window corner double knives angle sign indicating number, can increase group angle stability at to a great extent, the last stable connection of guarantee corner mutually perpendicular side, through the two-way fixed stay of the perpendicular side use with the injecting glue structure cooperation in later stage, improve whole aluminum alloy door and window's safety in utilization and life, the extensive popularization and use of being convenient for.

The utility model provides a technical scheme that its technical problem adopted is: the corner double-cutter corner connector for the aluminum alloy doors and windows comprises a corner connector body, wherein the section of the corner connector body is of a right-angle structure, and the corner connector body comprises an outer layer and an inner layer; the outer layer and the inner layer are vertically connected through a plurality of connecting plates; a plurality of open grooves are formed in the side wall of the outer layer along the length direction; slope surfaces are arranged at the intersection positions on the outer layer; the inner layer is provided with arc-shaped notches at the intersection positions.

Further, in the above technical solution, the cross section of the open slot is in one of a trapezoid shape, a rectangular shape or a square shape; the design can facilitate the fixed insertion of the double knives through the open slot.

Further, in the above technical solution, the inner layer, the outer layer and the connecting plate are of an integral structure; this can improve the intensity of whole angle sign indicating number.

Further, in the technical scheme, the end part of the inner layer inclines to the outer layer side by an angle of 3-5 degrees; the problem of difficult insertion that can effectively prevent that the fine deformation of window frame from leading to appears.

Further, in the technical scheme, the end part of the outer layer inclines to the inner layer side by an angle of 3-5 degrees; the problem of difficult insertion that can effectively prevent that the fine deformation of window frame from leading to appears.

Further, in the above technical solution, the end of the inner layer is spliced with the end of the corresponding outer layer to form a socket end; this facilitates free insertion of the sash after slight deformation.

The utility model has the advantages that: the utility model provides a pair of al-alloy door & window corner double knives angle sign indicating number can increase group angle stability at to a great extent, and the last stable connection of guarantee corner mutually perpendicular side uses through the injecting glue structure cooperation in the two-way fixed stay and the later stage on the vertical direction, improves whole al-alloy door & window's safety in utilization and life, is convenient for extensively promote and use.
