A pull rod 2 is slidably connected to the upper and lower parts of the right side of the inner wall of the door frame 1. An extrusion block 6 is connected to the upper and lower sides of the outer wall of the pull rod 2 via a movable component. Multiple sliding frames 8 are slidably connected to the upper and lower sides of the inner wall of the door frame 1. A sliding rod 9 is slidably connected to the inner wall of each sliding frame 8. A door / window body 7 is provided on the outer wall of each sliding rod 9. A fixing rod 4 is fixedly connected to the opposite side of the outer wall of the pull rod 2. A connecting block 5 is slidably connected to the outer wall of each fixing rod 4. The opposite end of each connecting block 5 is slidably connected to the upper and lower sides of the inner wall of the door frame 1. The front and rear ends of each connecting block 5 are fixedly connected to the opposite ends of the extrusion blocks 6. The rear side of the outer wall of the pull rod 2... Each of the sliding rods 9 is fixedly connected to a spring 11, the other end of which is fixedly connected to the upper and lower sides of the front end of the door frame 1 for disassembly of the door / window body 7. Each of the upper and lower ends of the door / window body 7 is fixedly connected to a mounting frame 12, the inner wall of which is provided with a slot 13. Each of the sliding rods 9 is fixedly connected to a block 11 on the left and right sides of the outer wall, the outer wall of which is provided on the inner wall of the slot 13, and the shape of the block 11 fits the slot 13. Each of the sliding rods 9 is fixedly connected to a spring 210 on the left end, the other end of which is fixedly connected to the left side of the inner wall of the sliding frame 8 for installation of the door / window body 7.
[0029] For details, please refer to Figure 3 and Figure 6 During installation, first press the pull rod 2, and insert the mounting frames 12 at both ends of the door and window body 7 into the sliding frame 8. After installation, release the pull rod 2, and push the sliding rod 9 to the right through the second spring 10 to lock the locking block 11 into the slot 13. At the same time, push the pull rod 2 forward through the first spring 3 to return it to its original position. Due to its detachable design, disassembly can be completed by pressing the door and window body 7 to the right and pushing the pull rod 2. The operation is simple, allowing for more thorough cleaning of the interior and exterior, avoiding problems such as dust accumulation and mold, extending the service life of the doors and windows, ensuring their normal function, reducing maintenance difficulty and cost, and allowing users to quickly replace doors and windows or adjust their positions according to different decoration styles and needs to adapt to different interior designs.
[0030] Reference Figure 1 and Figure 7 As shown, the door and window body 7 includes an outer glass layer 14, a hollow layer 15, an inner glass layer 16, a frame structure layer 17, a sealing layer 18, and a decorative layer 19.

[0032] Working principle: During disassembly, first push the door and window body 7 to the right and squeeze it to the right. Then press the pull rods 2 on both sides backward. The pull rods 2 drive the fixing rod 4 to move, causing the fixing rod 4 to slide on the inner wall of the connecting block 5. This causes the connecting block 5 to slide to the left, and the squeezing blocks 6 on both sides to move to the right. The squeezing blocks 6 squeeze the sliding rod 9 to the right, causing the sliding rod 9 to slide to the left. This also causes the locking blocks 11 on both sides of the outer wall to move to the left. Remove the locking blocks 11 from the slots 13, and then push the door and window body 7 forward to complete the disassembly. In use, the outer glass layer 14 provides impact resistance and enhances safety.
