The plates, profiles and other main finished materials used in the production and installation of ventilation pipes should comply with the design and relevant national standards for products, and should be certified for factory inspection. Materials should be inspected and accepted in accordance with relevant national standards when they are delivered to the site. As ventilation pipes are used more and more frequently, there are more and more structures for the installation of ventilation pipes, which provide more convenience for workers during installation.

[0003] In view of this, Chinese patent number CN117345963A proposes a ventilation duct that is easy to install.

When docking, the sealing gaskets 10 on one side of the two connecting pieces 2 contact each other to achieve sealing in the connection area;

[0028] Furthermore, a clamping rail 11 is fixedly provided on one side of the outer wall of the air duct 1 , and limiting grooves 12 are provided on both sides of the inner wall of the clamping rail 11 .

[0029] A limiting block 13 is inserted into the inner wall of the clamping rail 11 , and outer walls at both ends of the limiting block 13 are slidably connected to the inner walls of the two limiting grooves 12 .

[0030] An arc-shaped bracket 14 is fixedly provided on one side of the limit block 13, and an arc-shaped clamping strip 15 is fixedly provided on one end of the arc-shaped bracket 14. A protective pad 16 is fixedly provided on one side of the arc-shaped clamping strip 15, and one side of the protective pad 16 contacts the outer wall of the connecting air duct 1. After the limit block 13 slides onto the clamping rail 11, the outer walls at both ends thereof are clamped in the limit grooves 12 and are limited, so that the arc-shaped bracket 14 cannot fall off during support, and after the limit block 13 is clamped in the clamping rail 11, the protective pad 16 on one side of the clamping strip 15 just contacts the outer wall of the adjacent connecting air duct 1.
