Abstract
The utility model relates to a hydraulic cylinder which is suitable for movable furniture, and the front side of a piston rod is provided with a movable rigid valve block and a movable piston. When the piston rod retracts in the cylinder wall of the main body of the hydraulic cylinder to glide forwards, the piston rod can glide with larger resistance, thereby achieving the stable and smooth buffering function, and when the piston rod extends the cylinder wall of the main body of the hydraulic cylinder to glide backward, the piston rod can glide with smaller resistance and faster speed, thereby achieving the advantages of earthquake avoidance and noise reduction. The piston is provided with at least a thin elastic trip, and when the piston rod retracts to the cylinder wall, and the resistance born by the piston is smaller than the elastic recovery power of the thin elastic trip, a small salient part of the thin elastic trip can protrude at the back face and then form certain distance with the rigid valve block, which causes the piston rod to extend the cylinder wall with smaller resistance and faster speed.
