Hydraulic cylinder piston buffering structure

Abstract

The utility model relates to a hydraulic cylinder piston buffering structure which comprises a cylinder body, and a piston mechanism is arranged in the cylinder body. The piston mechanism comprises a piston rod, a piston A and a piston B are arranged on the piston rod, the piston B is slidably arranged on the piston rod, and a surge bin is formed between the piston A and the piston B; kinetic energy of the piston mechanism is converted into heat energy by compressing the inner cavity space of the cylinder body between the piston A and the piston B, so that impact of the piston mechanism on the cylinder body is reduced, mechanism damage caused by hard collision in the working process of the hydraulic cylinder is prevented, and the hydraulic cylinder is simple, efficient, safe and reliable.
