AI Technical Summary
Existing smoke pipe joints are difficult to position quickly and accurately during installation, resulting in poor sealing and leakage of dense smoke, which affects the efficiency and safety of fire smoke exhaust.
It employs a sealing ring, an arc-shaped magnet, and a fixing structure. A circular fixing is achieved by using a locking block and a semi-arc sleeve to form a sleeve rod. Combined with the design of a limiting block and a protruding rod, it achieves rapid installation, positioning, and high sealing performance.
It enables rapid disassembly and precise positioning of smoke pipe joints and fan joints, improving installation efficiency and sealing performance, preventing smoke leakage, and enhancing the reliability and safety of fire smoke exhaust.
