Description

Technical Field

[0001] The utility model belongs to the technical field of galvanized air ducts, in particular to a quick-connect galvanized air duct. Background Art

[0002] Existing cleanroom air supply and return ducts often utilize galvanized iron or stainless steel. After installation, these pipes require periodic anti-corrosion and cooling maintenance during subsequent use, increasing maintenance costs. Existing pipes are typically used once, and cooling measures are typically implemented after system installation. This makes maintenance difficult, resulting in poor pipe tightness and insulation effectiveness. Furthermore, since the entire piping system cannot be disassembled and can only be used once, its reusability is limited.

[0003] In the related art, a quick-connect galvanized air duct with publication number CN210978889U is disclosed, which includes an air duct, a connector A and a connector B. Trapezoidal protrusions are processed on the outer walls of both ends of the air duct, and the connectors A and B are both provided with dovetail grooves. The dovetail grooves are matched with the dovetail blocks formed by the trapezoidal protrusions connecting the two air ducts to fix the two air ducts in connection.

[0004] During use, the device relies on friction, which will cause wear between the slider and the slide groove, reducing the tightness and stability of the connection. During sliding, certain noise and vibration may occur, affecting the use effect and comfort. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-connect galvanized air duct. By setting a quick-connect mechanism, it solves the problem of wear between the slider and the slide groove, reducing the tightness and stability of the connection, and causing certain noise and vibration during sliding, which affects the use effect and comfort.

The output rod 13 transmits the force to the nail 18, and the nail 18 is fixed on the wall so that the first galvanized air duct 1 on the second fixing block 17 is fixed. At this time, pull the two handles 19 at the same time, and the two handles 19 drive the sliding sleeve 6 to move backward, and insert the second galvanized air duct 2 into the first galvanized air duct 1.
