Abstract
Description
Technical Field
[0001] This utility model belongs to the field of folding window technology, specifically relating to a high-rigidity steel corner bracket connecting component. Background Technology
[0002] Currently, the assembly of aluminum alloy window sashes typically involves inserting simple aluminum corner brackets at the four corners during the assembly process, and then fixing them with self-tapping screws from two perpendicular sides. Because these corner brackets are relatively thin and lack sufficient rigidity, they are mostly used for small, lightweight window sashes. The opening and closing of these sashes is usually limited to manual sliding or outward opening, with no high requirements for the overall rigidity and strength of the window sash.
[0003] Existing thermally broken aluminum alloy folding windows have two sashes arranged vertically. The lower sash is electrically driven, lifting it upwards to fold the two sashes together, thus opening the window; conversely, it closes. Due to the large size of the folding window sashes and the long operating stroke (single sash: 4 meters wide, 1.3 meters high, lifting stroke 2.6 meters), the two sashes need to span a large distance and undergo frequent lifting and folding operations. During opening, insufficient rigidity at the four corners of the folding window sash makes it prone to cracking, altering the flatness and diagonal dimensions of the sash. This changes the lifting trajectory, deteriorates the operating environment of the mechanism, increases frictional resistance, and generates noise. Furthermore, the installation and fixation of the lifting bearing seats also contributes to structural instability. Utility Model Content

[0028] like Figures 1 to 10 As shown, this utility model provides a high-rigidity steel angle bracket connecting component, including angle brackets located inside a thermally broken aluminum alloy profile. The angle brackets include a large steel angle bracket 1 and a small steel angle bracket 2, which are arranged in parallel and connected in the middle by angle bracket fixing screws 3 and double-ended bolts 4. A bearing seat 5 is installed at the end of the double-ended bolt 4. The thermally broken aluminum alloy profile includes a first thermally broken aluminum alloy profile 6 and a second thermally broken aluminum alloy profile 7 that are fixedly connected as one piece. The ends of the large steel angle bracket 1 and the small steel angle bracket 2 are located inside the first thermally broken aluminum alloy profile 6 and the second thermally broken aluminum alloy profile 7, respectively, and are connected by angle bracket fixing screws 3. Double-ended bolts 4 are installed on the large steel angle bracket 1 and the small steel angle bracket 2, and the other end of the double-ended bolt 4 is connected to the bearing seat 5. The bottom of the bearing seat 5 is tightly connected to the first thermally broken aluminum alloy profile 6.
[0029] like Figures 2 to 4 As shown, the steel large angle bracket 1 has an "L"-shaped cross-section. The steel large angle bracket 1 is provided with a first threaded through hole 11 and a second threaded through hole 12. There are six first threaded through holes 11, with every three forming a group. Two groups of first threaded through holes are located at both ends of the steel large angle bracket 1. There are seven second threaded through holes 12, with three forming a first group located at the bend of the steel large angle bracket 1. The remaining four are divided into two groups located at both ends of the steel large angle bracket 1. The axes of the first threaded through holes 11 and the second threaded through holes 12 are perpendicular to each other.
[0030] In this embodiment, the axes of each large angle code first threaded through hole 11 inside the large angle code first threaded through hole group are parallel to each other, and the axes of the through holes in the two large angle code first threaded through hole groups intersect inside the bend of the steel large angle code 1.

[0040] The bearing block 5 is in a "convex" shape structure. Through-holes are provided at both ends of the bearing block, and the ends of the double-headed bolt 4 pass through the through-holes of the bearing block and are sleeved with fixing nuts for fixation.
[0041] During the actual use process, a bolt positioning gasket 8 is installed at the bottom of the bearing block 5, and the bolt positioning gasket 8 can position the double-headed bolt 4 when the bearing block 5 is installed. The end of the double-headed bolt 4 is sleeved with a fastening nut, so as to fasten the bearing block 5. During the use process, the bearing block 5 will not loosen or the like.
