AI Technical Summary

Technical Problem

Traditional hydraulic pipeline connection methods are cumbersome and time-consuming, and are prone to loose connections or poor sealing, leading to hydraulic leaks, increased maintenance costs, and environmental pollution risks.

Method used

The system employs a quick-change hydraulic pipeline self-sealing connector, which enables rapid connection and disassembly by pressing the positioning pin and pulling the lever. Combined with the locking mechanism of the positioning pin and the pop-out groove, as well as the locking of the reinforcing rod and the groove, it ensures the stability and sealing of the connection.

Benefits of technology

It improves the efficiency of hydraulic system installation and disassembly, reduces operation steps and time costs, avoids hydraulic leakage, and reduces maintenance costs and environmental pollution risks.

Abstract

This utility model relates to the field of hydraulic system technology and discloses a quick-change self-sealing hydraulic pipeline connector, including a connecting pipe. Sealing rings are fixedly connected to the inner walls of both ends of the connecting pipe. This utility model allows personnel to quickly connect and disconnect the connecting pipe from the interface seat by pressing the positioning pin and pulling the lever. The entire process requires no tools, improving operational efficiency and convenience. It avoids the cumbersome steps and time consumption caused by complex threaded connections or clamp fixation in traditional connection methods, significantly improving the maintenance and replacement efficiency of the hydraulic system. The sealing rings fixedly connected to the inner walls of both ends of the connecting pipe fit tightly with the interface seat, forming a good sealing effect. Simultaneously, the locking mechanism of the positioning pin and the pop-out groove, as well as the locking of the reinforcing rod and the groove, further ensure the stability of the connection, effectively avoiding hydraulic leakage caused by loose connections and reducing hydraulic oil waste and environmental pollution caused by leakage.
