Hydraulic valve rod with plug anti-loosening structure

Abstract

The utility model discloses a hydraulic valve rod with a plug anti-loosening structure, and particularly relates to the technical field of hydraulic devices, the hydraulic valve rod comprises a valve rod body, an upper plug and an internal thread structure, the lower end of the valve rod body is provided with a connecting lug, the upper end of the valve rod body is provided with a valve rod connector, and the upper plug is installed in an inner cavity of the valve rod connector; the upper plug and the internal thread structure are sequentially connected with the valve rod in a meshed mode, so that two different thread meshing points can jointly provide a multi-time locking effect, the stability of overall connection is improved through interaction of the meshing points, the possibility of loosening in the working process is reduced, and the service life of the valve is prolonged. The upper plug can be stabilized during meshing through the inner screw structure, rotation or loosening of the upper plug due to vibration or impact in the working process is prevented, and therefore it is guaranteed that the whole structure is more stable, the position of the upper plug is fixed through the inner screw structure, relative movement between the valve rod and the upper plug can be effectively avoided, and the service life of the valve rod is prolonged. Therefore, abrasion and fatigue caused by frequent movement are reduced.
