[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles and fan materials. They are called aluminum alloy doors and windows. Aluminum alloy doors and windows include doors and windows with aluminum alloy as stress-bearing rods (base material) and wood and plastic composite, referred to as aluminum-wood composite doors and windows, aluminum-plastic composite doors and windows. Aluminum alloy doors and windows are often used to enclose balconies in home decoration. Aluminum alloy doors and windows are usually fixed to the wall with fasteners such as bolts, or directly welded to the wall.

[0003] In the prior art, a utility model patent with announcement number CN 221779317 U provides a fixing structure for wind-resistant aluminum alloy doors and windows, which includes an outer frame, a reinforced corner assembly, and a fixing assembly.

[0004] The fixing structure of the wind-resistant aluminum alloy door and window is difficult to turn due to the small size of the handle and the small force-bearing surface between the hand and the handle. The inner frame and the outer frame are fixed only by two sets of limit rods, and the stability is poor. Therefore, we propose a fixing structure of the wind-resistant aluminum alloy door and window to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a fixing structure for wind-resistant aluminum alloy doors and windows to solve the problems raised in the above-mentioned background technology.

A slot is provided on the inner wall of the outer frame, and a limiting device is inserted into the slot for movement, and the limiting device is used to limit the inner frame from rotating and opening on the outer frame. The limiting device includes a pin that moves through the side wall of the inner frame, and a pull rope is connected to the pin. The free end of the pull rope slides through a guide wheel in turn, moves through a spring and is fixedly connected to a sliding rod, and the guide wheel is used to guide the pull rope, and the spring is used to push one end of the sliding rod out of the inner frame.

[0007] Preferably, the slots are provided in three groups, the first group is provided at the top of the outer frame, the second group is provided at the bottom of the outer frame, and the third group is provided at the inner side wall of the outer frame.

[0008] Preferably, the outer frame and the inner frame are provided with at least two sets of flat hinges, and the width of the glass body is smaller than the width of the inner frame.

[0009] Preferably, the latch is arranged on a wall of the inner frame away from the casement hinge, the latch is on one side of the glass body, and one end of the latch is moved and inserted into the third group of slots.

[0010] Preferably, the length of the pull rope is greater than or equal to the sliding distance of the sliding rod in the inner frame, the pull rope moves through the partition, and the guide wheel is rotatably arranged in the inner frame.

[0011] Preferably, the partition is used to support the spring, and the partition is arranged in the inner frame, and the partition is between the spring and the guide wheel.

[0012] Preferably, the compressible length of the spring is greater than the length of the portion of the sliding rod extending out of the inner frame, and one end of the spring is connected to the partition, and the other end is connected to the sliding rod.

[0013] Preferably, the length of the sliding rod is less than or equal to half of the height of the inner frame, the sliding rod is slidably arranged in the inner frame, and the sliding rod is provided with two groups of symmetrically arranged on the inner frame on both sides of the latch.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Close the inner frame, and the inner frame is closed by rotating it on the outer frame through the flat hinge. Release the latch, and the spring returns to its original shape, pushing the two groups of sliding rods to move back to back and insert them into the first and second groups of slots respectively. The sliding rod moves and the pull rope is pulled to follow the movement. The pull rope slides through the guide wheel, pulling the latch to move away from the glass body, and pulling the latch to insert it into the third group of slots to complete the fixing work. When opening, just reverse the above steps and pull the latch toward the glass body to separate the latch from the third group of slots. Use the pull rope to pull the sliding rod to move toward the latch. When the sliding rod is separated from the first and second groups of latches, pull the inner frame to open it. When the sliding rod moves toward the latch, it compresses the spring, fixing the inner frame and outer frame through three points to improve stability. BRIEF DESCRIPTION OF THE DRAWINGS
