Furthermore, when connecting the corner brackets to the window frame connection groove, screws are required for fixing, which affects the assembly speed. Therefore, this does not meet the current requirements. To address this, we propose an aluminum alloy window frame assembly and its aluminum alloy window. Summary of the Invention

Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention pushes the second sliding plate, causing the second sliding plate to slide along the crossbar and compress the second spring to contract, and drives the insertion rod away from the handle, disengaging it from the current slot, thereby releasing the restriction on the handle and releasing the push on the second sliding plate, so that the insertion rod, under the elastic force of the second spring, penetrates and is inserted into the corresponding slot on the handle, thereby limiting the shaft and preventing the extension corner blocks on both sides from moving. 2.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0018] Please see Figures 1 to 7 The present invention provides an embodiment of an aluminum alloy window frame assembly and its aluminum alloy window, comprising a bottom frame 1 and a side frame 2. Both ends of the bottom frame 1 and the side frame 2 are provided with connecting grooves 3, and the interior of the connecting grooves 3 of the bottom frame 1 and the side frame 2 are connected by a limiting mechanism 8 to a connecting corner block 4. A through groove 401 is provided in the middle of the connecting corner block 4, and a width adjustment mechanism 5 is provided in the middle of the through groove 401. On both sides of the width adjustment mechanism 5 and inside the through groove 401, an extension corner block 6 is movably connected to extend through to the outside of the connecting corner block 4. Symmetrical sliding grooves 402 are provided on both sides of the inner wall of the through groove 401, and sliders 7 that are slidably connected to the sliding grooves 402 are fixedly connected to the outer surfaces of the extension corner blocks 6 on both sides.
[0019] The width adjustment mechanism 5 includes a shaft 501, a handle 502, a gear 503, and a rack 504. The shaft 501 is vertically fixed inside the through groove 401, and the top end of the shaft 501 extends through to the outer side of the upper end of the connecting corner block 4 and is fixedly connected to the handle 502. A groove 403 is provided on one side of the upper end of the connecting corner block 4. A crossbar 9 is fixedly installed inside the groove 403. A second sliding plate 10 is slidably connected to the outer surface of the crossbar 9. One side of the second sliding plate 10 is connected to one side of the inner wall of the groove 403. A second spring 11 is fixedly connected and wrapped around the outer surface of the crossbar 9. A plug rod 12 is fixedly connected to the side of the second sliding plate 10 away from the second spring 11. In the natural state of the second spring 11, the end of the plug rod 12 away from the second sliding plate 10 extends through to the outside of the groove 403. The outer surface of the handle 502 is provided with a number of slots 50201 that match the plug rod 12 along the axial direction, and the end of the plug rod 12 that extends through to the outside of the groove 403 is inserted into the corresponding slot 50201.
[0020] By pushing the second sliding plate 10, the second sliding plate 10 slides along the crossbar 9, compressing the second spring 11 to contract, and driving the insertion rod 12 away from the handle 502, disengaging from the current slot 50201, thereby releasing the restriction on the handle 502, and then the handle 502 can be rotated to drive the shaft 501 to rotate.
[0021] Gears 503 are fixedly connected to the upper and lower surfaces of the shaft 501 and inside the through groove 401. Racks 504 are fixedly connected to the upper and lower surfaces of the two extended corner blocks 6 on the side that are close to each other. The racks 504 on the left and right sides are staggered. The racks 504 mesh with the outer surfaces of the gears 503. By rotating the handle 502, the shaft 501 is driven to rotate. When the shaft 501 rotates, it drives the gears 503 on the outer surface to rotate. Then, the gears 503 mesh with the racks 504 on the front and rear sides, thereby causing the extended corner blocks 6 on both sides to move or move closer to each other along the slide groove 402. Thus, the connecting corner blocks 4 can be adjusted to a suitable insertion width according to the width of the connecting groove 3 inside the bottom frame 1 and the side frame 2.
[0022] The limiting mechanism 8 includes a first sliding plate 801, a first spring 802, and a limiting block 803. Movable cavities 601 are provided at the top and bottom of both ends of the two extended corner blocks 6. The first sliding plate 801 is slidably connected to the interior of the movable cavity 601. The first spring 802 is fixedly connected between one side of the movable cavity 601 and one side of the inner wall of the movable cavity 601. The limiting block 803 is fixedly connected to the side of the first sliding plate 801 away from the first spring 802. In its natural state, the end of the limiting block 803 away from the first sliding plate 801 passes through the movable cavity 601 and extends to the outside of the extended corner block 6. The side of the limiting block 803 away from the first sliding plate 801 is inclined. The inner walls of the connecting grooves 3 of the bottom frame 1 and the side frame 2 are each provided with limiting grooves 301 that match the limiting block 803. The end of the limiting block 803 extending to the outside of the extended corner block 6 slides and engages with the corresponding limiting groove 301.
[0023] By inserting the two ends of the connecting corner block 4 into the connecting grooves 3 of the bottom frame 1 and the side frame 2 respectively, the inner wall of the connecting groove 3 contacts the inclined surface of the upper and lower limiting blocks 803 of the extension corner block 6, thereby pushing the limiting block 803 to move and be stored in the interior of the movable cavity 601, and compressing the first spring 802. Then, when one end of the connecting corner block 4 is fully inserted into the interior of the connecting groove 3, the movable cavity 601 corresponds to the limiting groove 301 on the inner wall of the connecting groove 3. At this time, the limiting block 803 is inserted into the interior of the limiting groove 301 under the elastic force of the first spring 802, thereby connecting the bottom frame 1 and the side frame 2 with the connecting corner block 4.
[0024] An aluminum alloy window includes a window sash, which is installed inside an aluminum alloy window frame assembly.
[0025] When installing the aluminum alloy window frame assembly, by pushing the second sliding plate 10, the second sliding plate 10 slides along the crossbar 9, squeezing the second spring 11 to retract, and driving the insert rod 12 away from the handle 502, disengaging from the current slot 50201, thereby releasing the limitation on the handle 502. Then, the handle 502 can be rotated to drive the shaft 501 to rotate. When the shaft 501 rotates, it drives the gear 503 on the outer surface to rotate. Then, the gear 503 meshes with the racks 504 on the front and rear sides, thereby causing the extension corner blocks 6 on both sides to move or move closer to each other along the slide groove 402. Thus, the connecting corner blocks 4 can be adjusted to a suitable insertion width according to the width of the connecting groove 3 inside the bottom frame 1 and the side frame 2. After the adjustment is completed, the push on the second sliding plate 10 is released, so that the insert rod 12, under the elastic force of the second spring 11, penetrates and inserts into the corresponding slot 50201 on the handle 502, thereby limiting the shaft 501 and preventing the extension corner blocks 6 on both sides from moving. After the connecting corner block 4 is adjusted, insert both ends of the connecting corner block 4 into the connecting grooves 3 of the bottom frame 1 and the side frame 2 respectively. At this time, the inner wall of the connecting groove 3 contacts the inclined surface of the upper and lower limit blocks 803 of the extension corner block 6, thereby pushing the limit block 803 to move and be stored in the interior of the movable cavity 601, and compressing the first spring 802. Then, when one end of the connecting corner block 4 is fully inserted into the interior of the connecting groove 3, the movable cavity 601 corresponds to the limit groove 301 on the inner wall of the connecting groove 3. At this time, the limit block 803 is inserted into the interior of the limit groove 301 under the elastic force of the first spring 802, thereby connecting the bottom frame 1 and the side frame 2 with the connecting corner block 4.
