Novel section bar corner position pulling sheet, pulling set and novel section bar corner position system

Abstract

The invention discloses a novel section bar corner position pulling sheet, a pulling set and a section bar corner position system. The puling sheet comprises a pulling sheet main body. The pulling sheet main body is in a long stripped shape on the whole and bent into a connection section, a transition section and a hook-drawing section from the head end to the tail end; a connection hole is formed in the connection section; the least tail end of the hook-drawing section is provided with more than one draw hook; and straight-extending or bending directions of the draw hooks are opposite to an inflection direction of the connection section. The section bar corner position pulling set comprises a transverse pulling sheet and a vertical pulling sheet, and the two pulling sheets are connected together via a connection screw. The section bar corner position system comprises the section bar corner position pulling set, a transverse frame and a vertical frame, wherein the transverse frame is connected with the vertical frame via the draw hooks by the section bar corner position pulling set. Punching of the draw hook on the plate surface of the hook-drawing section can be unnecessary, and a preserved position can be applied for an empty-avoiding hole; and the section bar combination is uneasy to turn over. The novel section bar corner position pulling sheet, the pulling set and the section bar corner position system can be widely applied to assembling work of section bar corner position 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. [0003] The inventor once proposed ...

AI Technical Summary

Problems solved by technology

[0004] However, although the design of the set of pull code pieces, pull code sets and profile corner position system is relatively simple, it still has some room for improvement: in the cavity of the profile corner position, there are often some parts that need to be adjusted with tools. structure, at this time it may be necessary to extend the tool from the outside to the inside of the corner of the profile, but the hook section of the pull piece seals the tool's entrance and exit. If an avoidance hole is designed in the hook section, the pull piece There is no landing hook
