Abstract
The utility model relates to an oil buffer. The oil buffer comprises a cylinder, wherein a piston rod is perpendicularly and movably arranged in the cylinder; a main oil passage in the perpendicular direction is arranged at the lower end of the piston rod; a marble is contained in the main oil passage; a piston spring is connected below the marble; the upper end of the main oil passage in the piston rod is led to two subordinate oil passages which are led to the middle of the cylinder; the piston spring is arranged below the main oil passage. With the adoption of the technical scheme, the two subordinate oil passages are added, so that the buffer effect is improved; then an oil cup cap is added on the piston rod, so that the stability of the piston rod during movement is improved.
Description
Technical field
