AI Technical Summary

Technical Problem

The telescopic rod of existing hydraulic cylinders is prone to rotation and displacement under external force, resulting in a shortened service life.

Method used

An anti-rotation hydraulic cylinder was designed, comprising a fixed ring, a semi-circular clamping sleeve, and a second connecting seat. Through the cooperation of the slide rod and the lifting lug, the cylinder body is limited to lift and lower, preventing rotation.

Benefits of technology

This effectively prevents the hydraulic cylinder from rotating during extension and retraction, thus extending its service life.
