Reverse limiting structure of automobile shock absorber

The invention belongs to the technical field of automobile shock absorbers, and particularly relates to a reverse limiting structure of an automobile shock absorber. The reverse limiting structure ofthe automobile shock absorber comprises a shock absorber inner cylinder, a piston rod, a limiting gasket and a limiting block, the piston rod is arranged in an inner cavity of the shock absorber innercylinder, a piston is arranged at the right end of the piston rod, and gaskets are arranged on the left side and the right side of the piston; and the limiting gasket is arranged at the left end of the gasket on the left side, the limiting block is arranged on the left side of the limiting gasket, and the conical end of the limiting gasket is tightly attached to the gaskets. The gaskets are jacked through the limiting gasket, direct contact between the piston and the limiting block is prevented, gasket deformation caused by impact force generated by direct action of the limiting block and thegaskets of a piston valve
