AI Technical Summary
Existing metal hoses are prone to damage during use due to excessive bending or twisting at the connection or excessive tension caused by the shower head falling, resulting in water leakage or connection damage.
Design a metal corrugated flexible hose, in which the inner tube and the connector are connected by a buffer washer, and an elastic buffer is set between the outer tube and the connector. The end of the inner tube is fixed by a retaining ring and a plastic joint, and an elastic buffer is set between the sleeve and the connector on the outside of the outer tube. The connector is designed as a hexagonal nut for easy installation.
The design of buffer gaskets and elastic buffer components reduces the tensile force at the connection, extends the service life, improves the stability and sealing of the connection, and prevents hose rupture and leakage.
