[0030] Example 1, as Figure 1-6As shown, a flange-type structure air duct for ships includes a ventilation pipe 1 and several flange rings 4. An adjusting device 2 is provided between the outer surface of the ventilation pipe 1 and the inner wall of the flange ring 4. A reinforcement device 3 is provided on the inner wall of the ventilation pipe 1. The adjusting device 2 includes two rectangular rods 21. One side of the rectangular rod 21 is fixedly connected to the outer surface of the ventilation pipe 1. One side of the rectangular rod 21 is provided with several card grooves 22. The inner wall of the flange ring 4 is symmetrically provided with first rectangular grooves 23. The ventilation pipe 1 and the two rectangular rods 21 are respectively inserted into the inner walls of the flange ring 4 and the two first rectangular grooves 23. The inner wall of the first rectangular groove 23 is provided with a slide groove 24. A spring 25 is fixedly connected to one side of the inner wall of the slide groove 24. One end of the spring 25 is fixedly connected to a slider 26. The slider 26 is slidably connected to the slide groove 24. One side of the slider 26 is fixedly connected to a block 27. One end of the block 27 is inserted into the inner wall of the slot 22. When the vent 1 is installed in the ship through the flange ring 4 for use, the two sliders 26 on the flange ring 4 can be manually slid to a certain position in the inner wall of the slide groove 24 according to the distance between the reserved hole and the reserved bracket inside the ship, thereby driving the spring 25 to contract, so that the block 27 is retracted into the inner wall of the slide groove 24. At this time, the inner wall of the flange ring 4 and the first rectangular groove 23 are respectively slid to a certain position on the ventilation pipe 1 and the two rectangular rods 21. When the two adjacent flange rings 4 are adjusted to the same distance as the reserved holes or reserved brackets on the installation position, the slider 26 is manually released, so that under the reset action of the spring 25, the block 27 on the other side is clamped into the corresponding clamping groove 22, so that the adjusted flange ring 4 is fixed on the ventilation pipe 1 to a certain position, which is convenient for installing it at any installation position inside the ship, improving the applicability of the ventilation pipe 1 and facilitating its installation and use.

[0031] Reference Figure 1-6 As shown, this embodiment discloses a slider 26 having a T-shaped cross-section, and the inner wall of the chute 24 having a T-shaped cross-section. By configuring both the slider 26 and the chute 24 in a T-shape, the slider 26 is less likely to wobble when sliding up and down in the chute 24, resulting in more stable movement. A telescopic rod 28 is fixedly connected to one side of the inner wall of the chute 24. The outer surface of the telescopic rod 28 is sleeved and connected to the inner wall of the spring 25, and one end of the telescopic rod 28 is fixedly connected to one side of the slider 26. The provision of the telescopic rod 28 supports and reinforces the interior of the spring 25, making it less susceptible to damage during use and increasing its service life.

[0032] Reference Figure 1-6As shown, this embodiment discloses a second rectangular groove 29 formed on one side of the slider 26, and a plurality of anti-slip protrusions are fixedly connected to the inner wall of the second rectangular groove 29. By providing the second rectangular groove 29, it is difficult for one side of the slider 26 to completely cling to the rectangular rod 21 after the block 27 is inserted into the slot 22. This makes it convenient to manually buckle the block 27 and then pull the slider 26 and the block 27 out of the slot 22, thereby facilitating adjustment of the flange ring 4. The block 27 is made of iron, and a magnet block 210 is fixedly connected to the inner wall of the slot 22. One side of the magnet block 210 is magnetically attracted to one side of the block 27. By providing the magnet block 210, after the block 27 is inserted into the slot 22, one side will be attracted and fixed by the magnet block 210, making the clamping more secure and stable.

[0033] Reference Figure 1-6 As shown, this embodiment discloses a reinforcement device 3 including a plurality of reinforcement rods 31, one side of which is fixedly connected to the inner wall of the ventilation duct 1. A plurality of circular brackets 32 are fixedly connected to the inner wall of the ventilation duct 1, and the circular brackets 32 are interpenetratingly connected to the plurality of reinforcement rods 31. The plurality of reinforcement rods 31 and the plurality of circular brackets 32 are fixedly installed inside the ventilation duct 1 to enhance the overall strength of the ventilation duct 1, making it less susceptible to deformation and damage during transportation and use, thereby increasing the service life of the ventilation duct 1.

[0034] Reference Figure 1-6 As shown, this embodiment discloses that the circular bracket 32 ​​is in a vertical state with the reinforcement rod 31, and a plurality of reinforcement rods 31 and the circular bracket 32 ​​are arranged at equal distances. By arranging a plurality of reinforcement rods 31 and the circular bracket 32 ​​at equal distances, the interior of the ventilation duct 1 can be uniformly supported and reinforced, making it less likely to be damaged during use and transportation, thereby increasing its service life. Both sides of the reinforcement rod 31 are fixedly connected to a support rod, and one side of the support rod is fixedly connected to the inner wall of the ventilation duct 1. By providing the support rod, the connection area between the reinforcement rod 31 and the inner wall of the ventilation duct 1 can be increased, the distance of support and reinforcement can be extended, and the reinforcement effect and strength of the reinforcement rod 31 can be improved.

[0035] Working principle: when the ventilation pipe 1 is installed inside the ship through the flange ring 4 for use, it can be manually buckled into the second rectangular groove 29 according to the distance between the reserved hole and the reserved bracket inside the ship, and the two sliders 26 on the flange ring 4 are slid to one end in the inner wall of the slide groove 24 to a certain position, driving the spring 25 and the telescopic rod 28 to contract, so that the block 27 is retracted into the inner wall of the slide groove 24. At this time, the inner wall of the flange ring 4 and the first rectangular groove 23 are slid to one end on the ventilation pipe 1 and the two rectangular rods 21 to a certain position respectively, and the two adjacent flange rings 4 are adjusted to be consistent with the distance between the reserved holes or the reserved brackets at the installation position. When the slider 26 is manually released, the block 27 on the other side is snapped into the corresponding slot 22 under the reset action of the spring 25, and is adsorbed and fixed by the internal magnet block 210, so that the adjusted flange ring 4 is fixed on the ventilation pipe 1 to a certain position, making it easy to install it at any installation position inside the ship, improving the applicability of the ventilation pipe 1 and facilitating its installation and use.

[0036] Several reinforcing rods 31 and several annular brackets 32 are fixedly installed inside the ventilation pipe 1, which can enhance the overall strength of the ventilation pipe 1, making it less likely to be deformed and damaged during transportation and use, thereby increasing the service life of the ventilation pipe 1.
