| description | The utility model relates to a secondary buffer oil cylinder. The secondary buffer oil cylinder comprises a cylinder barrel, a cylinder cover, a cylinder bottom, a piston rod and a piston. An oil returning hole is formed in the cylinder bottom. The secondary buffer oil cylinder is characterized in that a blind hole is formed in the bottom of the piston rod, a buffer is arranged inside the blind hole, the buffer comprises a one-level buffer, a two-level buffer and a compressed spring, the two-level buffer is fixed inside the blind hole, the upper portion of the one-level buffer is limited inside the blind hole by a check ring, a gap is reserved between the one-level buffer and the inner wall of the blind hole, the compressed spring is arranged between the one-level buffer and the two-level buffer, a taper part is provided with the bottom of the one-level buffer, a two-level taper part is arranged at the bottom of the two-level buffer, and a throttle hole matched with the two-level taper part is formed inside t |
