Damping coefficient variable hydraulic buffer
The invention provides a damping coefficient variable hydraulic buffer which comprises a cylinder body, a piston rod, a piston, a floating platform, a spring, a pin and an end cover, wherein the piston and the piston rod are concentrically connected by screw threads; the pin is arranged in a small hole in the bottom surface of the piston; the compression spring and the floating platform are arranged at one end, connected with the piston, of the piston rod; the compression spring compresses the floating platform and the pin on the end surface of the piston; the end cover and the piston rod are concentric and are arranged at one end of the cylinder body; and damping holes are formed at one end, connected with the piston, of the piston rod. The buffer has an obvious buffering effect, is simple and reliable in structure, better in manufacturability and easy for engineering application.
