AI Technical Summary
Existing circular male elbow connectors are prone to core rotation and axial slippage during assembly, resulting in low assembly efficiency, unstable yield, and easy wear on threaded components.
The design employs a limiting structure consisting of a rubber core support ring, a housing, and a male elbow body. Through structures such as cantilever, limiting slots, and C-shaped retaining rings, the relative rotation and axial sliding of the rubber core and the male elbow body are restricted. A wave spring ring is set between the positioning seat and the second arm to reduce the locking force, ensuring rapid matching and stable connection.
It improved assembly efficiency, reduced wear, and ensured connection stability and yield.
