Profile corner system

Abstract

The invention discloses a profiled corner tension fitting unit, a profiled corner tension plate and a profiled corner system employing the profiled corner tension fitting unit and the profiled corner tension plate. The profiled corner tension plate comprises a plate body which is elongated and which is bent from front to tail to provide a connecting segment and a hooking segment; the connecting segment is provided with a connecting hole; the hooking segment is provided with more than one pull hook; each pull hook is straightly extended or bent towards the front of the plate body. The profiled corner tension fitting unit comprises a transverse tension plate and a vertical tension plate which are connected together through connecting screws. The profiled corner system comprises the profiled corner tension fitting unit, a transverse frame and a vertical frame; the profiled corner tension fitting unit allows the transverse frame and the vertical frame to be connected together through the pull hooks. The profiled corner tension plate, the profiled corner tension fitting unit and the profiled corner system have the advantages that parts are few, the structure is simple, the cost is low, connection is reliable, and the profiled corner tension plate, the profiled corner tension fitting unit and the profiled corner system are widely applicable to assembly of profiled corners of doors and windows.

Description

technical field

[0001] The invention relates to the field of door and window profile assembly structures, in particular to a profile corner position system in the assembly structure and assembly accessories used in the system. Background technique

[0002] In the profile assembly structure of doors and windows, there will inevitably be corner positions, such as the right-angle corner positions of doors and windows, etc., which are generally made of two profiles (or combined profiles) at a certain angle, obliquely cutting off the profile ends and adding Spliced ​​by connecting accessories. If the cutting angle is 45 degrees, standard right-angle frames for doors and windows can be spliced ​​and assembled. However, since the profiles are independent of each other, how to ensure the alignment of the intersection lines of the two, the alignment of the cutting bevels, and the leveling of the profile surfaces during splicing is a big problem.
