| description | The invention discloses a hydraulic oil cylinder with high buffering performance. The hydraulic oil cylinder comprises a cylinder barrel, wherein an oil cavity is formed in the cylinder barrel, a piston rod is arranged in the oil cavity, and an end cover is arranged at one end of the cylinder barrel. According to the oil cylinder, the operation speed of the piston rod is reduced by changing the injection speed of hydraulic oil through a first adjusting valve and a second adjusting valve, and the buffering effect is achieved from the exterior of the oil cylinder; an arc-shaped insertion plate at one end of a piston and an arc-shaped hole at the bottom of the end cover are matched with a first buffering spring, a buffering plug at the other end of the piston is matched with a buffering cover, a sliding cover in a buffering cavity and a second buffering spring, the stretching and retracting speed of the piston rod is buffered, then the buffering effect is achieved from the interior of the oil cylinder, buffering |
