Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0029] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a ventilation duct for building engineering, including two ventilation duct bodies 1 and a docking component 3. The outer wall of the ventilation duct body 1 is fixedly connected to an installation plate 2, and the side of the installation plate 2 is provided with a plurality of installation holes 4. The docking component 3 is located at one end of the two ventilation duct bodies 1 that are close to each other.

[0030] The specific settings and functions of its docking component 3 will be discussed below.

[0031] Reference Figure 3 and Figure 4As shown in this embodiment: the docking component 3 includes a connecting pipe 301, the two ends of the connecting pipe 301 are respectively attached to the close ends of the two ventilation duct bodies 1, and both ends of the connecting pipe 301 are provided with a plurality of fixing holes 302. Both ends of the ventilation duct body 1 are fixedly connected with a plurality of fixing plates 303, the size of the fixing plates 303 is adapted to the fixing holes 302, the surface of the fixing plates 303 is provided with insertion holes 304, the outer wall of the connecting pipe 301 is slidably provided with a plurality of insertion rods 308, the size of the insertion rods 308 is adapted to the insertion holes 304, the outer wall of the connecting pipe 301 is rotatably connected with a connecting ring 305, the side of the connecting ring 305 is provided with a plurality of connecting holes 306, the connecting holes 306 are set as arc holes, the inner wall of the connecting holes 306 is slidably connected with a connecting rod 307, and the arc surface of the connecting rod 307 is fixedly connected to one end of the insertion rod 308. By setting the docking component 3, ventilation ducts can be easily docked or disconnected, and the duct length can be quickly adjusted according to site space and schedule requirements, thereby improving the flexibility and adaptability of ventilation ducts. A threaded hole 310 is provided on the side of the connecting ring 305. A partition 311 is fixedly connected to the outer wall of the connecting pipe 301, and a bolt 312 is threaded through the side of the partition 311. The bolt 312 is matched to the size of the threaded hole 310. When the connecting ring 305 is rotated to drive the insertion rod 308 into the insertion hole 304, the bolt 312 will align with the threaded hole 310. At this time, rotating the bolt 312 to connect with the threaded hole 310 can lock the connecting ring 305. A guide block 313 is fixedly connected to one end of the bolt 312 near the threaded hole 310. The guide block 313 is designed with a conical structure. Because the guide block 313 fixed to one end of the bolt 312 is small in size, it achieves the effect of easily inserting the bolt 312 into the threaded hole 310. A positioning rod 309 is slidably inserted through the arc surface of the connecting rod 307, and one end of the positioning rod 309 is fixedly connected to the outer wall of the connecting tube 301. When the connecting hole 306 drives the connecting rod 307 to move, the positioning rod 309 can guide and position the connecting rod 307, thereby preventing rotational deviation of the connecting rod 307 during its movement.

[0032] Two sealing rings 314 are fixedly connected to the inner wall of the connecting pipe 301, and the outer wall of the sealing rings 314 fits against the inner wall of the ventilation duct body 1. When the connecting pipe 301 is connected to the ventilation duct body 1, the sealing rings 314 can block the tiny gaps between the connecting pipe 301 and the ventilation duct body 1, thereby improving the sealing performance of the connection between the connecting pipe 301 and the ventilation duct body 1.

[0033] The docking assembly 3 also includes two fixing rings 315. One side of the fixing ring 315 is attached to the end of the ventilation duct body 1 away from the connecting pipe 301. The side of the fixing ring 315 near the ventilation duct body 1 has several rectangular holes 316. The rectangular holes 316 are adapted to the size of the fixing plate 303. The side of the fixing ring 315 away from the ventilation duct body 1 is fixedly connected to a corrugated pipe 317. Before using the ventilation duct body 1, first attach the fixing ring 315 to the end of the ventilation duct body 1 away from the connecting pipe 301. This process requires inserting the fixing plate 303 on the fixed ventilation duct body 1 into the rectangular hole 316. Once the fixing plate 303 is inserted into the rectangular hole 316, the connection between the fixing pipe and the ventilation duct body 1 is completed. At this time, personnel can adjust the opening orientation of the corrugated pipe 317 to adjust the air inlet and outlet directions of the ventilation duct body 1. By setting the above structure, the air inlet and outlet directions of ventilation ducts used in building engineering can be adjusted. Adjusting the air inlet and outlet directions can optimize airflow organization, improve ventilation efficiency and comfort, and achieve precise local environmental control. The fixing ring 315 is set as a magnetic ring, and the fixing plate 303 is set as an iron plate. The fixing plate 303 and the fixing ring 315 are attracted to each other. By setting the fixing ring 315 as a magnetic ring and the fixing plate 303 as an iron plate, when the fixing plate 303 is inserted into the rectangular hole 316, the fixing ring 315 will attract the fixing plate 303, thereby making the connection between the ventilation duct body 1 and the fixing ring 315 more stable.

[0034] Detailed Instructions for Use: When connecting two ventilation duct bodies 1, first insert the fixing plates 303 of the two ventilation duct bodies 1, with their ends close to each other, into the fixing holes 302 at both ends of the connecting pipe 301. Once the fixing plates 303 are inserted into the fixing holes 302 and the ventilation duct body 1 is in contact with the connecting pipe 301, the insertion holes 304 on the fixing plates 303 will align with the insertion rods 308. Then, rotate the connecting ring 305 along the outer wall of the connecting pipe 301. The connecting holes 306 of the connecting ring 305 drive several connecting rods 307 to move simultaneously. When the connecting holes 306 drive the connecting rods 307 to move, the positioning rods 309 can guide and position the connecting rods 307, thus preventing rotational displacement during the movement of the connecting rods 307. The connecting rods 307 then drive the insertion rods... Move 308 so that the insertion rod 308 passes through the connecting pipe 301 and moves towards the insertion hole 304. When the insertion rod 308 is inserted into the insertion hole 304, the bolt 312 will align with the screw hole 310. At this time, rotate the bolt 312 to connect with the screw hole 310, which can lock the connecting ring 305. This completes the connection of the ventilation duct. After the ventilation duct is connected, personnel can use the mounting holes 4 and screws to fix the ventilation duct to the ceiling or wall of the building. Before using the ventilation duct body 1, first attach the fixing ring 315 to the end of the ventilation duct body 1 away from the connecting pipe 301. This process requires inserting the fixing plate 303 on the ventilation duct body 1 into the rectangular hole 316. After the fixing plate 303 is inserted into the rectangular hole 316... The connection between the fixed pipe and the ventilation duct body 1 can be completed. At this time, personnel can adjust the opening orientation of the corrugated pipe 317 to adjust the air intake and exhaust direction of the ventilation duct body 1. The air intake and exhaust direction of ventilation ducts used in building engineering can be adjusted to optimize airflow organization, improve ventilation efficiency and comfort, and achieve precise local environmental control. When it is necessary to separate the two ventilation duct bodies 1, first rotate the bolt 312 to separate it from the screw hole 310, then reverse the connecting ring 305. The connecting ring 305 drives several connecting rods 307 to move in the opposite direction through the connecting hole 306. When the connecting rod 307 drives the insertion rod 308 to separate from the insertion hole 304, the ventilation duct body 1 is then moved to separate the fixing plate 303 from the fixing hole 302. At this point, the separation of the ventilation duct body 1 can be completed. Since the guide block 313 fixed at one end of the bolt 312 is small in size, it is easy to insert the bolt 312 into the screw hole 310. In addition, when the connecting pipe 301 is connected to the ventilation duct body 1, the sealing ring 314 can block the tiny gap between the connecting pipe 301 and the ventilation duct body 1, thereby improving the sealing performance at the connection between the connecting pipe 301 and the ventilation duct body 1. Finally, by setting the fixing ring 315 as a magnetic ring and the fixing plate 303 as an iron plate, when the fixing plate 303 is inserted into the rectangular hole 316, the fixing ring 315 will attract the fixing plate 303, thereby making the connection between the ventilation duct body 1 and the fixing ring 315 more stable.
