AI Technical Summary
Technical Problem
Existing hydraulic joints are prone to loosening of the single-sided locking structure under vibration and high hydraulic pressure, leading to oil leakage at the connection.
Method used
The system employs a ring block and locking assembly in conjunction with a ball bearing structure. The movement of the ring block releases the limitation on the ball bearing, causing the ball bearing to squeeze and limit the second connector. The combination of a locking block and a rubber sleeve ensures connection stability, and a sealing ring prevents oil leakage.
Benefits of technology
Stable connection of hydraulic joints was achieved under vibration and high hydraulic pressure environments, avoiding oil leakage and improving the stability and sealing of the connection.
