[0002] An air duct is a pipeline system used for air transportation and distribution, including composite air ducts and inorganic air ducts. Among them, flexible air ducts are made of flexible materials that are anti-corrosive, airtight, and not prone to mildew. According to the cross-sectional shape, air ducts can be divided into circular air ducts, rectangular air ducts, oval air ducts, etc. Among them, circular air ducts have the smallest resistance but the largest height dimension and are complex to manufacture, so rectangular air ducts are mainly used in applications.

[0003] For example, the Chinese authorized patent with the publication number CN218091827U (a thermal insulation structure for an air duct): includes a pipe body, a thermal insulation layer wrapped on the outer surface of the pipe body, and a fixing member for fixing the thermal insulation layer. The fixing member includes an upper frame body and a lower frame body arranged oppositely. The upper frame body and the lower frame body are respectively sleeved on the top and bottom of the thermal insulation layer. Both ends of the upper frame body are fixedly connected with connection blocks. A clamping groove is opened on one side of the connection block. Connection grooves adapted to the connection blocks are opened at both ends of the lower frame body. A groove is opened on one side of the lower frame body where the connection groove is located. A spring is arranged in the groove. One end of the spring is fixedly connected with a clamping block adapted to the clamping groove. Through the setting of the fixing member, the thermal insulation layer can be quickly fixed, the operation is convenient, time-saving and labor-saving, and it helps to improve work efficiency.

[0004] However, the connection part of the thermal insulation air duct in the above-mentioned prior art is relatively simple, so the problem of poor sealing is likely to occur at the connection part during connection installation and use. Therefore, it does not meet the existing requirements. For this reason, we propose a connection structure of a thermal insulation air duct. Summary of the Invention
