By the cabinet, cam, shaft, bearings, guide rods, compression spring, guide sleeve, adjustment bolts, top cover, depending on the manhole covers and other components. The principle is that the cam guide in the process of rotating with the shaft-driven compression spring damping torque and damping torque is passed to the damping roller belt to maintain uniform motion. Its working principle is simple, reliable, safe, compact structure, small size, low accuracy requirements, processing and assembly is easy, convenient installation and maintenance, has a strong applicability.
