AI Technical Summary
Technical Problem
When the piston rod is repeatedly operated, high-speed movement causes vibration, increasing the spacing between the piston rod and the piston sleeve, causing liquid to leak.
Method used
A piston assembly is designed, including a piston sleeve and a piston rod body installed inside the piston sleeve. By providing a fixing ring, a protective sleeve, a fixing plate and a positioning rod on the piston rod body, the motion trajectory and vibration amplitude of the piston rod body are limited.
Benefits of technology
It effectively reduces vibration of the piston rod, increases stability and guide motion accuracy, prevents the piston rod from deviating from the predetermined trajectory, extends service life and improves working accuracy.

Abstract
The utility model discloses a piston assembly which comprises a piston sleeve and a piston rod body installed in the piston sleeve, a fixing ring is arranged on the upper side of the piston rod body so as to be connected with an external driving component to drive the piston rod body to move, and the circular outer wall of the piston sleeve is fixedly connected with a protective sleeve. The piston rod comprises a piston rod main body, the uppermost side of the circular outer wall of the piston rod main body is fixedly connected with a fixing plate, and the outer wall of the lower end of the fixing plate is fixedly connected with a positioning rod which downwards penetrates through the interior of a protective sleeve so as to limit the motion trail of the piston rod main body. The moving direction and vibration amplitude of the piston rod body can be limited through movement of the positioning rod in the protective sleeve, vibration of the piston rod body is reduced, stability is improved, guiding movement of the piston rod body is improved, and the piston rod body is prevented from deviating from a preset track.
