The invention relates to the technical field of hydraulic pressure, in particular to a hydraulic stepless position adjuster. The hydraulic stepless position adjuster aims at solving the technical problems that an existing hydraulic structure cannot be automatically unlocked, automatic unlocking cannot be realized, and the self-locking force and the movement resistance are not ideal enough. The hydraulic stepless position adjuster comprises a piston sub-structure arranged in an oil cavity in a floating way; the piston sub-structure is connected to the end of a piston rod and comprises a valve seat piston, a left spring arranged on the left side of the valve seat piston and a right spring arranged on the right side of the valve seat piston; and the left spring and the right spring are in a compressed state in a natural state. According to the hydraulic stepless position adjuster, the self-locking force Fsr is effectively adjusted, and the movement resistance Fmr is effectively adjusted.
Description
technical field [0001] The invention relates to the field of hydraulic technology, in particular to a hydraulic stepless positioner. Background technique [0002] In the design of the opening and closing system of many doors and windows, it is required that the doors and windows can be stopped at any angle. When starting from a static position, sufficient resistance is required, that is, the self-locking force Fsr (anti-wind, anti-gravity load, anti-vibration shock, etc.), open (closed) ) The movement resistance Fmr in the process is small enough. [0003] However, the existing hydraulic structure cannot automatically switch between static and moving states, and the self-locking force and moving resistance are not ideal enough. Contents of the invention [0004] The purpose of the present invention is to provide a hydraulic stepless positioner to solve the technical problems that the existing hydraulic structure cannot automatically switch between static and moving states...
