A soft bed pneumatic lifting mechanism

Abstract

The utility model discloses a soft bed pneumatic lifting mechanism, including base, the base top is equipped with the cylinder through screw installation, the both ends of cylinder are provided with the fixed cylinder and the moving link of buffer effect, realizes airflow control through first check valve and second check valve, realizes fixed cylinder internal gas backflow to enter the inside of cylinder when the cylinder drops, compared with prior art, the utility model has the beneficial effects, when the top plate drops, moving link promotes fixed cylinder internal gas to enter cylinder through first check valve, and the gas that cylinder discharges collides with each other, forms high -efficient air pressure buffer, significantly slows down the falling speed of top link, avoids the impact of hard landing to cylinder structure, reduces the risk of component wear and tear, prolongs cylinder life, and through spring secondary buffering, buffer spring and gas buffer synergistic effect, further absorb the kinetic energy in the process of falling, and double protection mechanism improves the stability of cylinder operation greatly, dynamic adjustment support range, enhances the jacking stability.
