Description

Technical Field

[0001] The utility model relates to the technical field of ventilation ducts, in particular to a ventilation duct with a detachable structure. Background Art

[0002] Ventilation ducts are metal or composite pipes used in ventilation and air-conditioning projects in industrial and civil buildings. They are a kind of municipal infrastructure designed to allow air circulation and reduce the concentration of harmful gases. Nowadays, ventilation ducts have been widely used in industrial and other projects.

[0003] The overall length of the existing air-conditioning ventilation duct is limited. Therefore, during the installation of the duct, it is necessary to combine multiple sections of the duct together. In order to achieve the connection between the ventilation ducts, the two ends of the duct are respectively fixedly connected with iron frames, and multiple through holes are opened on the iron frames. During the actual installation, the staff is required to bring the iron frames connected on the outside of the duct close to each other and align the through holes on the iron frames. Then another group of staff will pass multiple groups of bolts through each group of two aligned through holes, and install elastic pads and nuts on the bolts to achieve the mutual connection between the two adjacent sections of the air duct. The whole installation process is relatively laborious, and when it is necessary to clean the inside of the duct, the staff needs to remove multiple bolts and nuts in turn, which will consume a lot of labor time of the staff. For this reason, we propose a ventilation duct with a detachable structure to solve the above problems. Utility Model Content
