The utility model provides a non-linear hydraulic buffer structure for eliminating oil cylinder descending bottom
impact, which relates to an oil cylinder and comprises a buffer
piston arranged in the oil cylinder and a buffer
plunger coaxially pressed with the bottom of the oil cylinder into a whole, an oil duct is arranged in the buffer
plunger, and the section of the buffer
plunger is a streamline variable section. And the buffer plunger enters the cavity of the buffer
piston to form multi-section buffer. The utility model further provides the oil cylinder which comprises the nonlinear hydraulic buffering structure for eliminating the
impact of the descending bottom of the oil cylinder. The buffer plunger with the oil duct inside is arranged, the cavity correspondingly matched with the buffer plunger is arranged in the buffer plunger, and the buffer plunger is in a streamline variable cross-section design, so that a buffer curve is smoother, multi-section
speed reduction is realized in the whole buffer process, the abrupt feeling is eliminated, the buffer process tends to be gentle, internal
oil pressure is balanced, and the service life of the buffer plunger is prolonged. And the
impact of parts of the oil cylinder is reduced to the minimum, and the service life of the oil cylinder is effectively prolonged.
