[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 4This embodiment of a door and window installation subframe includes a lower frame 1, a side frame 2, and a connecting block 3. The lower frame 1 and side frame 2 serve as the core load-bearing structure, jointly forming the basic frame of the subframe, providing a stable support for door and window installation, effectively distributing the weight of the door and window itself and the external forces generated during use, ensuring the overall structural stability after installation. The connecting block 3 is used to connect the lower frame 1 and the side frame 2, achieving precise splicing and fixing of the two, avoiding misalignment or loosening after installation. The connecting block 3 has two sets of rollers 4 internally slidably connected. The rollers 4 reduce the friction when the locking pin 5 slides, ensuring the flexible movement of the locking pin 5. Each set of rollers... The outer wall of shaft 4 is connected with locking pins 5. Under the elastic force of spring 6, the locking pins 5 can be accurately locked into the slots 13 opened inside the lower frame 1 and side frame 2. The locking structure strengthens the connection stability between the lower frame 1, side frame 2 and connecting block 3 and prevents displacement of the connection part. The inner wall of each set of locking pins 5 is connected with spring 6, which provides continuous elastic support for the locking pins 5 and ensures that the locking pins 5 and slots 13 are always tightly fitted, avoiding the problem of loosening of the connection due to vibration and other factors during long-term use. The lower frame 1 and side frame 2 are both opened with slots 13, and the inner wall of each slot 13 is locked with the locking pin 5.

[0017] The inner walls of the lower frame 1 and the side frame 2 are connected with rubber pads 7. The rubber pads 7 can buffer the door and window when they are attached to the subframe, reduce collision and wear during installation and use, extend the service life of the door and window and the subframe, and enhance the sealing performance, isolate external dust, noise and airflow, and create a cleaner, quieter and more comfortable indoor environment. The outer walls of the lower frame 1 and the side frame 2 are provided with side grooves 9. The side grooves 9 can significantly improve the connection strength between the subframe and the wall, help the subframe maintain a more stable state after installation, and avoid loosening and displacement. The inner wall of each set of side grooves 9 is slidably connected to the inner wall of the connecting block 3. The inner wall of one set of side grooves 9 is connected with multiple connectors 10. Each connector 10 has a through hole 11. The through hole 11 provides a precise installation point for fixing the subframe to the wall and the subframe to the door and window body. During installation, bolts and other fasteners are simply passed through the through hole 11 and locked to achieve a firm connection between the components, fully ensuring the overall structural stability of the subframe after installation, and ensuring the safety and reliability of the door and window during use.

[0018] The lower frame 1 and the side frame 2 are both connected to anti-slip pads 12 on their outer walls. These pads increase the contact friction between the lower frame 1, the side frame 2 and the mounting surface, effectively providing both anti-slip and stability, significantly improving the stability of the subframe after installation and preventing positional shifts due to external force or vibration during use. The inner wall of the lower frame 1 has a drainage channel 8, which precisely guides rainwater and other fluids to drain quickly, promptly draining water accumulated in the subframe area. This prevents water accumulation from causing corrosion, deformation, or other damage to the subframe and its associated doors and windows, extending the overall service life of the component. Both the lower frame 1 and the side frame 2 have cavities 14 inside, which significantly reduce the overall weight of the subframe. This design reduces the difficulty of handling and the load-bearing pressure on the wall during installation, and also provides ample installation space for core reinforcement structures such as support columns 17, making subsequent assembly more convenient. Each cavity 14 has multiple sets of slots 15 on its inner wall. The slots 15 are used to install the top plate 16 and provide connection points for the support columns 17. The inner wall of each set of slots 15 is connected to the top plate 16, and the outer wall of each set of top plates 16 is connected to the support columns 17. The top plate 16 and the support columns 17 form a cooperative force-bearing structure, which can provide strong support and reinforcement for the subframe, significantly enhancing the overall structural strength of the subframe, enabling it to more stably withstand the weight of the doors and windows themselves as well as external wind force, collision and other pressures, ensuring the safety and stability of the doors and windows for long-term use.

[0019] The working principle of the above embodiments is as follows: First, using the two sets of rollers 4 slidably connected inside the connecting block 3, and the locking pins 5 connected to the outer wall of each set of rollers 4 and the springs 6 connected to the inner wall of the locking pins 5, the locking pins 5 are engaged with the locking grooves 13 opened inside the lower frame 1 and the side frame 2, thus achieving the initial connection between the connecting block 3 and the lower frame 1 and the side frame 2. Next, the connecting block 3 is slidably inserted into the side grooves 9 opened on the outer wall of the lower frame 1 and the side frame 2. At the same time, with the help of multiple connectors 10 connected to the inner wall of one set of side grooves 9, and through the through holes 11 opened inside the connectors 10, the connection structure can be further fixed. The rubber pads 7 connected to the inner walls of the lower frame 1 and the side frame 2 can provide a tight connection between the subframe and the outer frame. The anti-slip pads 12 connected to the outer wall can enhance the anti-slip performance. When there is water flow at the lower frame 1, it will be guided through the guide grooves 8 opened in the inner wall. In addition, the cavity 14 opened inside the lower frame 1 and the side frame 2, and the multiple sets of slots 15 opened in the inner wall, together with the top plate 16 connected to the inner wall of the slots 15 and the support column 17 connected to the outer wall of the top plate 16, can provide support for the subframe structure and ensure the stability and structural strength of the subframe during the installation of doors and windows.

[0020] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
