A hydraulic quick coupling for disc brakes on oil drilling rigs
By designing a hydraulic quick-connect coupling for disc brakes on oil drilling rigs, and employing a threaded connection and sealing mechanism between a threaded sleeve and a connecting ring, the problems of complex connection and poor sealing in existing technologies have been solved. This achieves both quick connection and good sealing, ensuring the stable operation of the disc brake system.

AI Technical Summary
The existing hydraulic joints for disc brakes on oil drilling rigs are complex to connect and disassemble, time-consuming, and have poor sealing performance, making them prone to hydraulic oil leakage and affecting the stable operation of the disc brake system.
A hydraulic quick-connector for disc brakes on oil drilling rigs was designed. It uses a threaded connection between a threaded sleeve and a connecting ring, combined with a sealing mechanism and a leak-proof mechanism, to achieve quick connection and disassembly. The sealing is ensured by the squeezing action of the limit ring and the air bladder, and the flow and sealing of hydraulic oil are achieved by the cooperation of gears and torsion springs.
It enables rapid connection and disconnection of hydraulic hoses for disc brakes on oil drilling rigs, improves the sealing of the connection, avoids hydraulic oil leakage, ensures the stable operation of the disc brake system and the sealing of hydraulic oil, and prevents external impurities from entering.
