AI Technical Summary
Traditional quick-connect couplings lack a quick-plug structure, resulting in low efficiency in hose connection and disassembly, especially in full-flow dual-interlock liquid-cooled quick-connect systems where a large number of hoses need to be managed.
Design a pluggable and rotatable quick-connect coupling structure, including a pin, a quick-connect coupling body and a hose coupling body. The quick connection and disconnection of the hose is achieved by limiting the pin in the annular groove. The hose can rotate freely 360° in the coupling and is equipped with a sealing ring to prevent liquid leakage.
It enables quick connection and disconnection of hose connectors without complete disassembly, significantly reducing combing time, improving connection efficiency, and ensuring sealing.
