The invention relates to a liquid damping shock absorber. Aiming at the defects that a driver cannot be kept connected with a frame when a vehicle is turned over due to poor tension resistance in a traditional liquid damping shock absorber, the invention discloses the liquid damping shock absorber. The liquid damping shock absorber comprises a main spring cup, wherein the upper part of the main spring cup is filled with rubber; a main spring core insert which is fixedly connected with a mounting bolt of the driving cab is embedded into the rubber; an anti-pulling plate connected with the frame is arranged at a cup mouth of the main spring cup; a through hole for allowing the mounting bolt of the driving cab to penetrate through is formed in the middle of the anti-pulling plate; the radial dimension of the through hole is smaller than that of the main spring core insert; a transverse shock clearance is formed between the hole wall of the through hole and the mounting bolt of the driving cab; and a vertical shock clearance is formed between the anti-pulling plate and the main spring core insert. When the shock absorber is mounted, the anti-pulling plate is fixedly connected with the frame; and when the vehicle is turned over, the main spring core insert cannot penetrate through the anti-pulling plate so as to realize the connection maintenance of the driving cab and the frame.
