DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 to further illustrate the present application in detail.

[0020] An embodiment of the present application discloses a door and window frame installation structure. Refer toFigures 1-4 , including a wall body 1, with a door and window frame 2 provided on the inner side of the wall body 1. Installation plates 3 are symmetrically installed on both sides of the inner wall of the wall body 1. A plurality of positioning rods 5 are evenly and fixedly installed on the surface of the installation plates 3. Limiting grooves 6 are opened at the bottoms of the positioning rods 5. Rectangular grooves 7 are opened on both sides of the door and window frame 2. A plurality of installation holes 8 are evenly opened near the inside of the rectangular grooves 7 at both ends of the door and window frame 2. The plurality of positioning rods 5 are respectively connected to the inside of the installation holes 8, thus realizing the preliminary positioning and connection of the door and window frame 2 and the wall body 1, making the installation of the door and window frame 2 more accurate and convenient, and being able to quickly install the door and window frame 2 to the predetermined position. L-shaped movable plates 9 are provided on the inner sides of the rectangular grooves 7. A plurality of limiting clamping plates 10 are evenly and fixedly installed on the inner sides of the L-shaped movable plates 9. The plurality of limiting clamping plates 10 are respectively clamped in the limiting grooves 6. During installation, only need to align and insert the positioning rods 5 into the installation holes 8. Under the action of the return springs 11, the limiting clamping plates 10 are clamped in the limiting grooves 6, playing a limiting role for the door and window frame 2 inside the wall body 1, and the installation can be completed. Return springs 11 are fixedly installed at the bottoms of the L-shaped movable plates 9. By adopting the combined structure of the positioning rods 5, limiting grooves 6, L-shaped movable plates 9, limiting clamping plates 10 and return springs 11, the use of screws to fix the door and window frame 2 is avoided, reducing the loosening phenomenon caused by screw rust, and improving the stability and safety of the door and window frame 2. The bottoms of the return springs 11 are fixedly installed at the inner bottoms of the rectangular grooves 7. During disassembly, by pressing the L-shaped movable plates 9, the limiting clamping plates 10 are separated from the limiting grooves 6, thus realizing the disassembly of the door and window frame 2, saving installation and maintenance time.

[0021] Refer to Figures 2-3 , slide rails 12 are opened on the inner sides of the rectangular grooves 7. Sliders 13 adapted to the slide rails 12 are fixedly installed on the sides of the L-shaped movable plates 9. The sliders 13 are slidably connected to the inside of the slide rails 12, thus making the movement of the L-shaped movable plates 9 smoother and more stable, and being able to accurately realize the clamping and separation of the limiting clamping plates 10 and the limiting grooves 6, ensuring the convenience and reliability of the installation and disassembly of the door and window frame 2. A plurality of expansion bolts 4 are evenly provided on the surface of one end of the two installation plates 3. The inner sides of the plurality of expansion bolts 4 penetrate through the installation plates 3 and extend into the wall body 1, thus being able to firmly fix the installation plates 3 on the wall body 1, providing a stable support for the installation of the door and window frame 2. Compared with the traditional screw fixation, the fixation method of the expansion bolts 4 is more resistant to the influence of external forces, reducing the loosening phenomenon caused by long-term use or external forces, and extending the service life of the door and window frame 2.

[0022] Refer to Figure 4, rotating rods 14 are rotatably connected to the inner four corners of the door and window frame 2. Fixed blocks 15 are fixedly installed at both ends of the four rotating rods 14. Adjusting screws 16 are threadedly connected to the inside of the fixed blocks 15. Handwheels 17 are fixedly installed on the outer sides of the adjusting screws 16. Clamping blocks 18 are fixedly installed on the inner sides of the adjusting screws 16. The inner sides of the clamping blocks 18 are attached to the outer surface of the wall 1. When the handwheel 17 is rotated, the adjusting screw 16 rotates within the fixed block 15, driving the clamping block 18 to move towards the wall 1, causing the clamping block 18 to closely adhere to the outer surface of the wall 1, enhancing the connection stability between the door and window frame 2 and the wall 1, and reducing the possibility of the door and window frame 2 shaking or loosening during use.

[0023] The implementation principle of an installation structure of a door and window frame in an embodiment of the present application is as follows: During specific use, first, the mounting plate 3 is fixed to both sides of the inner wall of the wall 1 through expansion bolts 4. Then, the mounting holes 8 on both sides of the door and window frame 2 are aligned with the positioning rods 5, and the door and window frame 2 is pushed towards the wall 1, causing the positioning rods 5 to insert into the mounting holes 8. During this process, the L-shaped movable plate 9 is squeezed, and the return spring 11 is compressed. When the limit card plate 10 is aligned with the limit groove 6, under the action of the return spring 11, the limit card plate 10 is clamped in the limit groove 6, thereby fixing the door and window frame 2 to the wall 1. When it is necessary to disassemble the door and window frame 2 for maintenance or replacement, simply press the L-shaped movable plate 9 to disengage the limit card plate 10 from the limit groove 6, and then pull out the door and window frame 2 from the positioning rod 5.
