Abstract

The invention provides an air pipe connecting structure. A first air pipe (10) and a second air pipe (20) are connected by the air pipe connecting structure, the air pipe connecting structure comprises a soft connector (30) and a rigid connecting device, and the soft connector (30) is hermetically connected between the first air pipe (10) and the second air pipe (20); and the rigid connecting device comprises a first fixing part, a second fixing part and an adjusting part, the first fixing part is fixedly connected to the first air pipe (10), the second fixing part is fixedly connected to the second air pipe (20), and the adjusting part is used for changing and locking the distance between the first fixing part and the second fixing part. The first air pipe is hermetically connected with the second air pipe through the soft connector of the air pipe connecting structure, the distance between the first fixing part and the second fixing part is changed through the adjusting part of the rigid connecting device, so that the axial distance between the first air pipe and the second air pipe is adjusted, and after the distance between the first fixing part and the second fixing part is locked by the adjusting part, the rigidity of connection between the first air pipe and the second air pipe can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of duct ventilation, and more particularly relates to an air duct connection structure. Background technique [0002] In a long air duct pipeline, sometimes two air ducts need to be connected from the middle. There are two main connection methods in the prior art, one is a rigid connection and the other is a soft connection. [0003] The Chinese invention patent application with the publication number CN 102345770A discloses a connection structure of the ventilation pipe port. The connection structure of the air pipe is a rigid connection. Axial dimensions cannot be adjusted. [0004] The authorized announcement number is CN 201522064U Chinese utility model patent discloses a flexible connection structure for air ducts. Very poor, if there is no rigid support nearby, there will be strong vibration and interface misalignment. Contents of the invention [0005] The purpose of the present invention...
