[0002] Composition of air duct: Air duct is a piping system used for air transportation and distribution. Air duct can be classified according to cross-sectional shape and material. According to cross-sectional shape, air duct can be divided into circular air duct, rectangular air duct, oblate air duct and so on. Among them, circular air duct has the smallest resistance and the largest height dimension, and is complex to make, so rectangular air duct is mainly used. According to material, air duct can be divided into metal air duct, composite air duct and so on.

[0003] After searching, in the prior art, publication number CN01259507.1 discloses a polymer air duct sheet whose thickness is selected according to the cross-sectional area of ​​the air duct, and the surface layer is formed by polymer foaming to form semicircular holes, which has excellent properties such as noise reduction, light weight, and heat insulation. The polymer air duct is formed by polymer sheet through adhesive, and there is no metal reinforcement ring inside and outside the air duct. The cleaning rod can be supported by round steel rods, and the metal reinforcement strips and reinforcement strips further strengthen the strength of the air duct. Round steel cleaning rods are provided in the middle part of the upper and lower parts of the air duct, and metal corners are provided at the four corners outside the air duct. Metal reinforcement rings are provided around the outer surface of the air duct, and polymer materials are wrapped in the metal reinforcement rings to ensure that the air duct as a whole can withstand pressure, make it flat, meet the standard, and adjust to the accurate size with nuts.

[0004] However, the device and the prior art still have the following defects:

[0005] The existing full-array high-speed air duct will produce greater vibration, which will cause the overall connection to loosen, and the overall exhaust process will also produce greater noise, which will not only affect people working around it, but may even cause greater damage to the pipes, reducing the overall practicality.

[0013] Furthermore, there are four groups of mounting blocks inside the fixed outer tube corresponding to the four walls of the fixed outer tube, and the fixed outer tube is adapted to the shape and size of the protective inner tube.

[0014] By adopting the above technical solution, there is a gap between the fixed outer tube and the protective inner tube, thereby ensuring that the sound-absorbing filler can be filled between the fixed outer tube and the protective inner tube to form a good sound-absorbing structure, thereby increasing the overall sound-absorbing protection effect.

[0015] Furthermore, the horizontal center line of the fixed outer tube overlaps with the protective inner tube, and the vertical center line of the fixed outer tube overlaps with the protective inner tube.

[0019] In summary, the beneficial technical effects of the utility model are:

[0020] 1. The positioning plug-in frame and the positioning card-jointed frame are used for plug-in fixation to ensure good stability after overall installation, and the connection will not produce too much deviation, thereby ensuring good overall anti-seismic effect, thereby producing the effect of shock absorption and noise reduction;

[0021] 2. The fixing screws and fixing screw holes corresponding to the positioning and plug-in frame are used for fixing, which ensures good stability after the overall installation, increases the overall installation stability, and thus produces a stable installation effect;
