[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution: an easy-to-assemble anti-fall-off smoke exhaust fire damper, including a valve body 1 and a fixing plate 16. Mounting plates 2 are fixedly connected to both sides of the valve body 1. A first shock-absorbing pad 6 and a second shock-absorbing pad 7 are fixedly connected to both sides of the two mounting plates 2. By setting the first shock-absorbing pad 6 and the second shock-absorbing pad 7, after the valve body 1 is installed with the pipeline, the vibration brought by the pipeline to the valve body 1 can be reduced, and the connection sealing effect can be improved, resulting in good performance.

[0026] Two sets of fixing plates 16 are provided. The lower ends of the two sets of fixing plates 16 are fixedly connected to the base blocks 8. The base blocks 8 have an installation groove 10 inside. The installation groove 10 has a threaded rod 11 inside. A rotating handle 9 is fixedly connected to one side of the threaded rod 11. The outer surface of the threaded rod 11 is symmetrically threaded with anti-detachment brackets 12. By setting the base blocks 8, installation grooves 10, threaded rods 11, rotating handles 9, and anti-detachment brackets 12, the fixing effect on the valve body 1 is further improved, preventing it from falling off during installation or under vibration, and increasing the safety of use.

[0027] The surface of the mounting plate 2 has several mounting holes 5 to facilitate bolting the valve body 1 to the pipeline. The top of the valve body 1 is equipped with a controller 3, and the inside of the valve body 1 is equipped with a valve plate 4. The upper end of the bottom block 8 is fixedly connected with a second protective pad 14. One side of each of the two anti-detachment brackets 12 is fixedly connected with a first protective pad 13. By setting the first protective pad 13 and the second protective pad 14, the valve body 1 is protected to prevent damage. One side of the threaded rod 11 is fixedly connected with a bearing 15. By setting the bearing 15, the rotation of the threaded rod 11 is facilitated. The bearing 15 is fixed to the side wall of the mounting groove 10. The lower end of the anti-detachment bracket 12 is slidably connected to the bottom wall of the mounting groove 10 to prevent the anti-detachment bracket 12 from rotating with the rotation of the threaded rod 11.

[0028] Working principle: When in use, the fixing plate 16 is fixed on the pipe fixing bracket, the valve body 1 is placed on the base block 8, and the valve body 1 is fixed to the pipe with bolts. After fixing, rotate the rotating handle 9. Rotating the handle 9 drives the threaded rod 11 to rotate. The threaded rod 11 drives the anti-detachment bracket 12 to move. The anti-detachment bracket 12 further fixes the valve body 1, improves the fixing effect of the valve body 1, and reduces the risk of falling off.
