AI Technical Summary
Existing ventilation duct connection methods suffer from low connection strength, easy loosening, high labor intensity during installation, high construction difficulty, and inconvenience in operation, especially in narrow spaces.
The ventilation duct connection mechanism adopts a pin-type connection mechanism. The connection buckles of the ventilation duct are set at intervals at the end of the ventilation duct. The connection buckles of adjacent ducts are staggered and coupled by a pin passing through the connection buckles in sequence. Combined with elastic gaskets and a two-stage pin structure, the space requirement is reduced.
It improves connection strength and reliability, reduces the labor intensity and construction difficulty for installers, increases construction efficiency, and is suitable for operation in confined spaces.
