[0002] Fire-resistant doors and windows refer to door and window products that can resist flame combustion and the influence of high temperature for a certain period of time. Fire-resistant doors and windows usually adopt incombustible or difficult-to-combust materials, such as fireproof glass, fireproof board, special sealing materials, etc. When processing fire-resistant doors and windows, they need to be painted. Painting can provide a protective film to protect the doors and windows from environmental factors. When painting, the doors and windows need to be fixed. Fixing the doors and windows can ensure that the doors and windows do not move during the painting process, avoiding uneven painting or missed painting.
[0003] When the currently used fixing structure for the production of fire-resistant doors and windows is in use, it cannot drive the doors and windows to rotate. The immobile doors and windows will cause the paint film in some parts to be too thick or too thin, affecting the appearance and protective effect. There will be dead corners that are difficult for the spray gun to reach on the immobile doors and windows, and these places will not be effectively painted, resulting in omission and insufficient protection. Summary of the Utility Model

The other ends of the two rotating shafts are both fixedly connected with limiting components, and the limiting components are used to limit the rotating shafts.
[0006] Furthermore, both sides outside the placement frame are fixedly connected with fixing boxes. Inside both the two fixing boxes are fixedly connected with hydraulic cylinders. The output ends of both the two hydraulic cylinders are fixedly connected with fixing frames. Both sides inside the fixing frames are threadedly connected with screw rods. The upper part of the screw rod is fixedly connected with a turning handle. The bottom of the screw rod is threadedly connected with a pressing plate.
[0007] Further, the limiting component includes a disc, the disc is fixedly connected to one end of the rotating shaft away from the fixed box, fixed rods are fixedly connected to the opposite sides of the two discs, pulleys are fixedly connected to the other ends of the fixed rods, and multiple pulleys are all slidably connected to the inside of the slide rail.
[0008] Further, slide rails are provided on one side inside both of the two support plates.
[0009] Further, slide rods are fixedly connected to both sides inside the placement frame, and return springs are sleeved on both outer sides of the two slide rods.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Referring to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model: a fixing structure for the production of fire-resistant doors and windows, including a support frame 1 and a placing frame 21. Both sides inside the support frame 1 are fixedly connected with support plates 4. One side of the right support plate 4 is fixedly connected with a lining plate 2. The upper part of the lining plate 2 is fixedly connected with a motor 3. The output end of the motor 3 is fixedly connected with a driving gear 5. Both sides inside the two support plates 4 are rotatably connected with rotating shafts 7. Both outer sides of the two rotating shafts 7 are fixedly connected with driven gears 6. The upper part of one of the driven gears 6 is meshed with the driving gear 5. The relative ends of the two rotating shafts 7 are both fixedly connected with fixed boxes 12. The other ends of the two rotating shafts 7 are both fixedly connected with a limiting component for limiting the rotating shaft 7. The limiting component includes a disc 8. The disc 8 is fixedly connected to the end of the rotating shaft 7 far from the fixed box 12. Both opposite sides of the two discs 8 are fixedly connected with fixed rods 9. The other ends of the fixed rods 9 are fixedly connected with pulleys 10. Multiple pulleys 10 are all slidably connected inside the slide rails 11. Slide rails 11 are provided on one side inside the two support plates 4.
[0025] When the motor 3 starts to work, its output end will drive the driving gear 5 to start rotating. The rotation of this driving gear 5 is not isolated. It can drive the driven gear 6 to rotate accordingly. As the driven gear 6 rotates, the rotating shaft 7 also starts to rotate. The rotating shaft 7 is divided into left and right parts. The right part of the rotating shaft 7 can make the left part of the rotating shaft 7 rotate synchronously through the function of the placement frame 21. When the two rotating shafts 7 start to rotate, they will drive the disc 8 to rotate. The function of this disc 8 is to transmit power, so that the fixed rod 9 and the pulley 10 also start to rotate. The rotation of the pulley 10 enables them to slide inside the slide rail 11. The slide rail 11 can ensure that the pulley 10 can slide smoothly and steadily. Under the action of the pulley 10, the two rotating shafts 7 drive the fixed box 12 and the placement frame 21 to rotate. The placement frame 21 can not only drive the fireproof doors and windows to rotate, but also ensure the stability and accuracy of the rotation.
[0026] Refer to Figure 2 、 Figure 3 and Figure 5 , both outer sides of the placement frame 21 are fixedly connected with fixed boxes 12. Hydraulic cylinders 13 are fixedly connected inside both fixed boxes 12. Output ends of both hydraulic cylinders 13 are fixedly connected with fixed frames 14. Both sides inside the fixed frames 14 are threadedly connected with screw rods 16. The upper parts of the screw rods 16 are fixedly connected with turning handles 15. The bottoms of the screw rods 16 are threadedly connected with pressing plates 17. Both sides inside the placement frame 21 are fixedly connected with sliding rods 18. Both outer sides of both sliding rods 18 are sleeved with return springs 20. Both sides of both fixed frames 14 are fixedly connected with sliders 19. Multiple sliders 19 are all slidably connected to the outer sides of the sliding rods 18. One end of the return spring 20 is fixedly connected inside the placement frame 21, and the other end of the return spring 20 is fixedly connected with a slider 19. Both fixed frames 14 are slidably connected inside the placement frame 21. The placement frame 21 is rotatably connected inside the support frame 1.
[0027] Accurately place the doors and windows to be processed at the central position of the placement frame 21. Then, start the two hydraulic cylinders 13 so that their output ends can push the fixed frames 14 to move. When the fixed frames 14 start to move, they will drive the sliders 19 to slide on the outer sides of the sliding rods 18. During this process, the movement of the sliders 19 will exert a stretching effect on the return springs 20, thereby making the two fixed frames 14 approach each other. According to the specific dimensions of the doors and windows, adjust the distance between them. When the pressing plates 17 move to the upper sides of the doors and windows, it is necessary to rotate the turning handles 15. The rotation of the turning handles 15 will drive the screw rods 16 to rotate, and the rotation of the screw rods 16 will make the pressing plates 17 move downward. In this way, the pressing plates 17 can tightly press the doors and windows.
[0028] Working principle: First, place the doors and windows to be processed in the middle of the placement frame 21, and start the two hydraulic cylinders 13. The output ends of the hydraulic cylinders 13 push the fixed frame 14 to move. When the fixed frame 14 moves, it drives the slider 19 to slide outside the slide bar 18. When the slider 19 moves, it stretches the return spring 20. The two fixed frames 14 move closer to each other, and the distance is adjusted according to the size of the doors and windows. When the pressing plate 17 moves to both sides of the upper part of the doors and windows, turn the handle 15. The rotation of the handle 15 drives the screw rod 16 to rotate, and the rotation of the screw rod 16 drives the pressing plate 17 to move downward, so that the pressing plate 17 tightly presses the doors and windows, thereby effectively realizing the pressing and fixing of the fire-resistant doors and windows, preventing them from shifting or shaking during the painting process, and ensuring the stability of the doors and windows during painting; after fixing the fire-resistant doors and windows, start the motor 3. The output end of the motor 3 drives the driving gear 5 to rotate. The rotation of the driving gear 5 drives the driven gear 6 to rotate. The rotation of the driven gear 6 drives the rotating shaft 7 to rotate. The rotating shaft 7 on the right drives the rotating shaft 7 on the left to rotate synchronously through the placement frame 21. When the two rotating shafts 7 rotate, they drive the disc 8 to rotate. The rotation of the disc 8 drives the fixed rod 9 and the pulley 10 to rotate, so that the pulley 10 slides inside the slide rail 11. Under the action of the pulley 10, the two rotating shafts 7 drive the fixed box 12 and the placement frame 21 to rotate, and the placement frame 21 drives the fire-resistant doors and windows to rotate, thereby effectively realizing the rotation of the fire-resistant doors and windows, which can help the painting workers to spray paint evenly from multiple angles, ensure that each side of the doors and windows can obtain the same thickness of the coating, and improve the uniformity of the painting.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
