Adjustable shock absorber

Abstract

The utility model discloses an adjustable shock absorber, which relates to the technical field of shock absorbers, and comprises a base, the top of the base is fixedly connected with a hydraulic oil tank, the top of the hydraulic oil tank is fixedly connected with an oil seal device through an opening, a piston rod is slidably connected in the oil seal device, the top of the piston rod is fixedly connected with a threaded section, and the threaded section is fixedly connected with the hydraulic oil tank. The top of the threaded section is fixedly connected with a mounting top plate, the rod wall of the threaded section is in threaded connection with an adjusting threaded sleeve, and the bottom of the adjusting threaded sleeve is rotationally connected with an annular pressing plate. According to the base provided by the utility model, the side stress protection of the piston main rod is enhanced on the basis of adjusting the hydraulic oil level in the adjustable shock absorber cavity, so that the problems that when an existing adjustable shock absorber is used, only the tightness of a spring can be adjusted, and the internal oil pressure height cannot be adjusted are solved; and the piston main rod is easy to bend due to lack of side support during inclined stress.
