[0039] Please refer to Figures 1-12 A building aluminum alloy door and window assembly component includes four middle panels 2, both ends of the middle panels 2 are provided with a fitting surface with an angle of forty-five degrees, the fitting surfaces on the four middle panels 2 are fitted one-to-one to form a square frame for installing glass panels, both ends of the middle panels 2 are provided with card slots, and each two adjacent card slots are jointly provided with a connecting component 3, the rear outer wall of the middle panel 2 is fixed with a rear covering panel 5, the front outer wall of the middle panel 2 is provided with a front covering panel 1, and the top of the middle panel 2 is provided with a clamping component 4 for clamping the glass.

[0040] From the above, it can be seen that the four middle panels 2 are assembled at the window frame mounting opening on the wall, and then the two adjacent middle panels 2 are fixed together using the connecting component 3, and then the glass is fixed in the frame formed by the four middle panels 2 through the clamping component 4, and then the front covering panel 1 is used to cover and fix it.

[0041] Furthermore, the clamping assembly 4 includes a movable clamping plate 401 and a fixed clamping plate 403. Both sides of the bottom of the movable clamping plate 401 are provided with a first extension plate with an integral structure therewith, and a second extension plate with an integral structure therewith is provided at the middle position of the bottom of the movable clamping plate 401. A first guide hole is provided on the outer wall of the first extension plate, and a guide column 402 is slidably arranged in the first guide hole. A threaded hole is provided on the outer wall of the second extension plate, and a threaded column 404 is connected to the threaded hole through a thread. First grooves are provided at both sides of the outer wall of the front side of the intermediate plate 2, and a second groove is provided at the middle position of the outer wall of the front side of the intermediate plate 2. One end of the guide column 402 is fixed on the inner wall of one end of the first groove, and one end of the threaded column 404 is rotatably installed on the inner wall of one end of the second groove. The fixed clamping plate 403 is fixed on the top of the intermediate plate 2.

[0042] As can be seen from the above, the setting of multiple guide columns 402 allows the movable clamping plate 401 to move only in a straight line; the glass is placed on the four fixed clamping plates 403, and then the threaded column 404 is rotated.

At this time, under the action of the third spring, the second positioning column 20 enters the first positioning hole 7, thereby fixing the front cover plate 1 on the middle plate 2, thereby completing the hidden fixation. A strong magnet is inserted into the magnet slot 18, and the second positioning column 20 is attracted. The second positioning column 20 is disengaged from the first positioning hole 7, so that the front cover plate 1 can be pulled out. It can be seen that this device can be hidden fixed to prevent others from opening it by mistake.

One end of the adjusting column 304 is connected to the internally threaded metal cylinder 303 by a thread. The adjusting column 304 is a double-step cylindrical structure. A hexagonal groove is provided at one end of the adjusting column 304.

[0052] From the above, it can be seen that the V-shaped block 301 is inserted into two adjacent slots, and then the adjusting column 304 is rotated.

[0060] Step 3: Place the window in the frame and secure it with the clamping assembly 4;

[0061] The fourth step is to install it on the front cover plate 1.

[0062] In summary, with the help of the above technical solution of the present invention: four intermediate panels 2 are assembled at the window frame installation opening on the wall, and then the two adjacent intermediate panels 2 are fixed together using the connecting component 3. The specific steps are: insert the V-shaped block 301 into the two adjacent card slots, and then rotate the adjusting column 304. The adjusting column 304 moves toward the V-shaped block 301. The V-shaped block 301 pushes the two first positioning columns 302 outward until the first positioning columns 302 enter the positioning holes of the card slots, thereby fixing the two adjacent intermediate panels 2. Then, the glass is fixed in the frame formed by the four intermediate panels 2 by the clamping component 4.
