AI Technical Summary
The connection of existing tunnel construction ventilation devices is inconvenient, and the connection structure of existing technology devices is complex, which leads to connection difficulties, low assembly efficiency, and instability.
The connection structure consists of a snap-fit socket and a snap-fit ring. Initial precise docking is achieved through a wedge-shaped slot and annular magnetic block. The locking structure, consisting of a fixed plate, elastic locking rod, slot, slide, and locking hole, ensures the tightness and stability of the air duct connection. At the same time, the filter screen forms a filtration structure to block dust and impurities.
It achieves efficient, stable and safe duct connection, ensures the cleanliness of the ventilation environment, provides a good ventilation environment, improves assembly efficiency and safety, provides good operational reliability of the ventilation system, and provides a good ventilation environment.
