Abstract
The utility model relates to the technical field of automobile shock absorbers, in particular to a piston rod structure of a shock absorber. The piston rod structure comprises an oil storage cylinder, a compression valve assembly, a piston assembly, a piston rod, a guide device assembly, an oil seal assembly, a bottom cover, a dustproof cover, a support body and a spring plate. The middle of the piston rod is provided with a limiting device which comprises a base and a stress plate. The stress plate is connected to the base in a screwed mode. The base is in interference connection with the piston rod in a sleeved mode. The piston rod structure is reasonable in structure; the piston rod is provided with the limiting device in a sleeved mode, and when the stroke of the piston rod is excessively large, the stress plate props up the guide device assembly, so that collision or friction between the compression valve assembly and the guide device assembly is prevented, and the service life of the shock absorber is prolonged.
