[0001] The present invention relates to the technical field of aluminum alloy frame connection, in particular to a corner positioning connection structure of an aluminum alloy door and window frame. Background Art

[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, referred to as aluminum doors and windows. Aluminum alloy doors and windows include doors and windows with aluminum alloy as the base material of load-bearing rods and wood and plastic composites, referred to as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows. The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw materials, aluminum surface treatment and internal processing quality, and the price of aluminum alloy doors and windows. Under the existing technology, the connection between the corner frames of the common aluminum alloy doors and windows on the market is fixed by threading strips. Although this structure can effectively meet the connection needs, its overall connection strength is low. Some structures are not stable enough and are easily twisted under strong external forces. For this reason, we propose a corner positioning connection structure for aluminum alloy door and window frames. Summary of the Invention

[0003] The present invention provides a corner positioning connection structure for an aluminum alloy door and window frame to solve the above-mentioned deficiencies in the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] Furthermore, the first fixing mechanism includes movable grooves opened on the front and back sides of the first support block and the second support block, the four movable grooves are fixedly connected to the inside of connecting rods, one end of the four clamping plates is opened to form a mounting hole, the connecting rods are movably sleeved inside the mounting hole, the four first springs are fixedly connected to the inside of the four movable grooves, the other ends of the four first springs are fixedly connected to the inner sides of the four clamping plates, the inner sides of the four clamping plates are rotatably connected to extension plates, and the other end of the extension plates is fixedly connected to a triangular slider.

[0007] Furthermore, the second fixing mechanism includes spring holes respectively opened on the first support block and the second support block, the interior of the two spring holes are fixedly connected to the second springs, the other ends of the two second springs are fixedly connected to the connecting plates, and the tops of the two connecting plates are fixedly connected to the bayonet pins.

[0008] Furthermore, the adjustment mechanism includes a movable opening opened inside the first support block and the second support block, the movable opening is movably sleeved with an adjustment block, a through hole is opened on the adjustment block, a triangular slide groove is opened inside the through hole, the triangular slider is movably sleeved inside the triangular slide groove, a limiting plate is fixedly connected to the adjustment block, a limiting groove 1 is opened inside the movable opening, the limiting plate is movably sleeved inside the limiting groove 1, a third spring is fixedly connected to the movable opening, and the other end of the third spring is fixedly connected to the other end of the adjustment block.

[0009] Furthermore, a second limiting groove is provided inside each of the four movable grooves, and both sides of the four clamping plates are fixedly connected with a limiting rod, which is movably sleeved inside the second limiting groove.

[0010] Furthermore, a first movable hole is opened at the top of the second supporting block corresponding to the bayonet pin, and the bayonet pin on the left side is movably sleeved inside the first movable hole.

[0013] Furthermore, the first support block and the second support block are smaller in volume than the fixing member, and their cross sections are L-shaped.

[0014] Compared with the existing technology, the beneficial effects of the present invention are:

[0015] 1. The present invention installs a first fixing mechanism, wherein the first fixing mechanism generates an upward thrust on the card plate through the first spring, and the card plate is flipped upward around the connecting rod by this thrust. The flipping of the card plate enables the first support block and the second support block to quickly fix the aluminum alloy door and window frame. At the same time, by pressing the adjustment block to move inward so that the extension plate enters the interior of the through hole, the first spring generates a pulling force on the card plate, so that the card plate moves inward, and at the same time, the third spring generates a thrust on the adjustment block, so that the adjustment block moves outward so that the triangular slider slides outward along the triangular slide groove so that the card plate returns to its outward position.

[0016] 2. The present invention installs a second fixing mechanism, wherein the second fixing mechanism generates an upward thrust on the connecting plate through a second spring. The upward movement of the connecting plate will simultaneously drive the latch to move upward, and the upward movement of the latch performs a secondary fixing process on the aluminum alloy door and window frame.

[0017] To sum up, the equipment has novel design and simple operation. The equipment can not only quickly position the aluminum alloy door and window frames through the first support block and the second support block, but also quickly fix the aluminum alloy door and window frames once through the clamping plate, and quickly fix the aluminum alloy door and window frames twice through the clamping pin, which effectively improves the effect and efficiency of the first support block and the second support block in quickly positioning and fixing the aluminum alloy door and window frames, and at the same time improves the overall connection strength, structural stability and anti-twisting effect.
