[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] 1. By opening a transmission cavity at the upper and lower ends inside the frame in the present utility model, threaded rods are rotatably arranged inside the transmission cavity. After placing the door and window structure inside the frame, only need to rotate the threaded rod, and the threaded rod will drive the lifting plate to move vertically, so that the first clamping block can be clamped into the clamping grooves at the upper and lower ends of the door and window structure, thereby fixing and limiting the upper and lower ends of the door and window structure.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.
[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: a quick-installation polyurethane pultrusion door and window installation structure, including a frame 1 and a door and window structure 2, and the door and window structure 2 is located inside the frame 1. Transmission cavities 3 are opened on the upper and lower sides inside the frame 1;
[0026] It further includes a threaded rod 4, which rotates at the middle position inside the transmission cavity 3. A lifting plate 5 is threadedly connected to the outside of the threaded rod 4. First clamping blocks 6 are welded to one end surface of the lifting plate 5. One end of each first clamping block 6 penetrates and extends to the outside of the transmission cavity 3, and the first clamping blocks 6 are all slidably matched with the transmission cavity 3;
[0027] It further includes first moving blocks 14, which are arranged on both sides inside the transmission cavity 3. Second moving blocks 15 are arranged on one side of each first moving block 14. First sliding rods 16 are arranged on the other side of each first moving block 14. Second sliding rods 17 are arranged on both sides inside the transmission cavity 3. The first sliding rods 16 and the second sliding rods 17 are adhesively fixed to the transmission cavity 3. The first sliding rods 16 and the first moving blocks 14 and the second sliding rods 17 and the second moving blocks 15 are all connected by connecting blocks 19, and the first sliding rods 16 and the second sliding rods 17 are all slidably matched with the connecting blocks 19. Second clamping blocks 20 are fixed to the inner sides of the second moving blocks 15. One end of each second clamping block 20 penetrates and extends to the outside of the transmission cavity 3, and the second clamping blocks 20 are all slidably matched with the transmission cavity 3.
[0028] During use, the door and window structure 2 is placed inside the frame 1. The second rotating shaft 10 is rotated by inserting an inner hexagon wrench into the inner hexagon groove 13. The meshing transmission between the two bevel gears 11 drives the first rotating shaft 9 and the threaded rod 4 to rotate synchronously. The rotation of the threaded rod 4 enables the lifting plate 5 to move vertically under the axial limit of the guiding rod 7, thereby driving the first clamping blocks 6 to be inserted into the clamping grooves 21 at the upper and lower ends of the door and window structure 2, realizing the fixation of the upper and lower ends. At the same time, the movement of the lifting plate 5 drives the first moving block 14 to squeeze the second moving block 15 through the L-shaped block 8, so that the second clamping blocks 20 are inserted into the clamping grooves 21, completing the fixation of both sides of the door and window structure 2. The entire installation process only requires rotating the second rotating shaft 10, realizing the quick installation of the door and window structure 2 and improving the efficiency.
[0029] Please refer to Figure 4, a return spring 18 is sleeved outside the second sliding rod 17. One end of each return spring 18 is connected to the transmission cavity 3, and the other end of each return spring 18 is connected to the connection block 19. The arrangement of the return spring 18 enables the second moving block 15 to automatically return to its original position, thereby driving the second latch 20 out of the internal of the card slot 21;
[0030] Please refer to Figure 4 , two card slots 21 are provided at the upper and lower ends and on both sides of the door and window structure 2, and the card slots 21 are adapted to the first latch 6 and the second latch 20 respectively. Such a design enables the door and window structure 2 to be stably fixed in multiple directions by multiple latches during installation, ensuring the firmness and safety of the installation;
[0031] Please refer to Figure 4 , a hidden groove 12 is provided at the front side of the upper and lower ends of the frame 1. A second rotating shaft 10 is rotatably arranged inside the hidden groove 12. One end of each second rotating shaft 10 penetrates and extends into the internal of the transmission cavity 3, and the second rotating shafts 10 are rotatably connected to the transmission cavity 3. The design of the hidden groove 12 enables the second rotating shaft 10 and related transmission mechanisms to be hidden inside the frame 1 when not in use, which is both beautiful and safe. At the same time, it is convenient for the operator to adjust when needed. An internal hexagonal groove 13 is provided at the front end of the second rotating shaft 10. The provision of the internal hexagonal groove 13 enables the operator to conveniently adjust the rotation of the second rotating shaft 10 through an internal hexagonal wrench, thereby controlling the installation and removal of the door and window structure 2;
[0032] Please refer to Figure 4 , one end of each threaded rod 4 is provided with a first rotating shaft 9. One end of the first rotating shaft 9 and the outer wall of one end of the second rotating shaft 10 located inside the transmission cavity 3 are both provided with bevel gears 11, and the bevel gears 11 are meshed with each other. Through the meshing connection of the bevel gears 11, the transmission between the second rotating shaft 10 and the first rotating shaft 9 is realized, so that when the second rotating shaft 10 is rotated, the first rotating shaft 9 and the threaded rod 4 can be driven to rotate simultaneously, improving the transmission efficiency;
[0033] Please refer to Figure 1 , two guide rods 7 are adhesively fixed inside the transmission cavity 3. The guide rods 7 penetrate through the lifting plate 5, and the guide rods 7 are slidably matched with the lifting plate 5. The design of the guide rods 7 limits the rotational movement of the lifting plate 5, enabling it to only slide up and down along the guide rods 7, thereby ensuring the stability and reliability of the lifting plate 5;
[0034] Please refer to Figure 1 and Figure 3 , the lifting plate 5 and the first moving block 14 are connected by an L-shaped block 8. The design of the L-shaped block 8 enables the lifting plate 5 to drive the first moving block 14 to move synchronously, thereby realizing the extrusion or release of the second moving block 15.
[0035] Working principle: When in use, place the door and window structure 2 inside the frame 1. The operator inserts an Allen wrench into the Allen slot 13 and rotates the second rotating shaft 10 through the Allen wrench. The second rotating shaft 10 will drive one of the bevel gears 11 to rotate. Since the two bevel gears 11 are in meshing transmission, it will drive the other bevel gear 11 to rotate the first rotating shaft 9. The first rotating shaft 9 will drive the threaded rod 4 to rotate synchronously. The threaded rod 4 will drive the lifting plate 5 to rotate synchronously. Since the lifting plate 5 is in sliding fit with the two guide rods 7, the lifting plate 5 will be axially limited. The rotation of the lifting plate 5 will be converted into vertical movement up and down. The movement of the lifting plate 5 can drive the first clamping block 6 to move synchronously, so that the first clamping block 6 can be inserted into the clamping slots 21 at the upper and lower ends of the door and window structure 2, and then the upper and lower ends of the door and window structure 2 can be fixed and limited. At the same time, when the lifting plate 5 moves vertically, it will drive the L-shaped block 8 to move synchronously. The L-shaped block 8 will drive the first moving block 14 to move synchronously. The movement of the first moving block 14 will squeeze the second moving block 15. The movement of the second moving block 15 will stretch the return spring 18, and the second moving block 15 will drive the second clamping block 20 to be inserted into the clamping slots 21 on both sides of the door and window structure 2, so that the two sides of the door and window structure 2 can be fixed and limited. Furthermore, the upper and lower ends and both sides of the door and window structure 2 can be fixed and limited synchronously. The whole process can be achieved only by rotating the second rotating shaft 10, completing the rapid installation of the door and window structure 2 and improving the production efficiency. When it is necessary to remove the installation of the door and window structure 2, just rotate the second rotating shaft 10 in the reverse direction, so that the lifting plate 5 can move in the reverse direction, and the first clamping block 6 can be pulled out of the inside of the clamping slot 21. The reverse movement of the lifting plate 5 will cause the first moving block 14 to move in the reverse direction, and the extrusion limit on the second moving block 15 can be released. At this time, under the elastic recovery effect of the return spring 18, the position of the second moving block 15 can be restored, and then the second clamping block 20 can be driven to move out of the inside of the clamping slot 21, so as to complete the removal of the door and window structure 2.
