Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum alloy door and window structure, specifically an aluminum alloy door and window protective grille installation structure. Background Technology

[0002] Aluminum alloy doors and windows are widely used in homes and offices. Aluminum alloy doors and windows can accommodate large window sashes. However, to improve the safety of large window sashes, protective grilles can be installed on the window sashes to prevent outsiders from entering the room and to prevent people inside the room from accidentally falling out of the window.

[0003] Existing aluminum alloy window and door protective grilles involve machining blind holes in the window and door sash material during the manufacturing stage, then inserting the grille members into these holes for fixation. During on-site installation, the pre-installed grille-equipped windows and doors are directly installed. Therefore, consumers must decide whether to install grilles when ordering aluminum alloy windows and doors, and once selected, later modifications are extremely difficult. Forced modifications require damaging the original window sash structure. Furthermore, aluminum alloy windows and doors typically include screens in addition to glass sashes; removing or installing the grille will also affect the normal use of the screens. Summary of the Invention

[0004] To address the aforementioned issues, this utility model provides an aluminum alloy door and window protective grille installation structure. The protective grille can be quickly installed and removed from the door and window frame. The protective grille can be installed on or not installed on the existing door and window frame as needed. Even if the protective grille is removed, it will not damage the original door and window structure, thus increasing the range of choices for consumers regarding door and window protective grilles.

[0005] The specific solution of this utility model is as follows:

[0006] An aluminum alloy door and window protective grille installation structure is disclosed. The main body of the door and window includes fixed glass and movable glass. The movable glass is fixed by a sash, the outer side of which is fixed to a subframe, and the outer side of the subframe is fixed to a frame / middle rail. A screen frame is fixed to the inner side of the extended side of the frame / middle rail. The screen frame is connected to the screen sash by a hinge. The edge of the screen mesh is fixed on the screen sash. The screen frame is also fixed to the partition frame by screws with nuts. The partition frame is fastened to the end of the grille strip by screws.

[0007] The screen frame is installed on the extended side of the frame / middle rail. The screen and the partition frame can be installed on the screen frame at the same time. The screen and the lattice strip can be installed independently. Consumers can choose to install the screen or the lattice strip separately, or both at the same time. The screen or the lattice strip can be removed at any time without affecting the original structure of the door and window.

[0008] A yarn pressure strip is also fastened to the yarn fan, and the yarn pressure strip presses the edge of the yarn mesh tightly with an adhesive strip. After the yarn mesh is pressed tightly with the adhesive strip, the yarn mesh is taut and not easy to loosen; the yarn pressure strip adopts a plug design, and after the hook-shaped plug is inserted, it can be fastened without fasteners, which is convenient for disassembly and assembly.

[0009] The cross-section of the partition frame profile is groove-shaped. The screws used to fasten the partition frame to the gauze frame are screwed in outwards, while the screws used to fasten the partition frame to the grid strip are screwed in inwards, and the two are arranged alternately.

[0010] The grid strips are designed with 10mm round internal threads, which can be directly connected to the profiles with screws, making construction convenient. At the same time, the visible surface is only 1 / 3 of that of conventional grid strips (30mm wide) on the market, greatly reducing obstruction of the field of vision.

[0011] The advantages of this utility model are:

[0012] 1. The structure of this utility model allows for quick installation and removal of the protective grille from the door and window frame. The protective grille can be installed on or not installed on the existing door and window frame as needed. Even if the protective grille is removed, it will not damage the original door and window structure, thus increasing the range of choices for consumers regarding door and window protective grilles.

[0013] 2. This utility model has a compact structure, and the overall thickness of the doors and windows can be compressed to less than 120mm, making it exquisite and beautiful. Attached Figure Description
