[0002] There are two main forms of various existing vibration-damping and shock-isolating devices, one is the wire rope type and the other is the rubber pad type. The wire rope type is a wire rope structure that realizes the vibration reduction function through the elastic force of the wire rope. It has the characteristics of high reliability and easy maintenance, but it has the disadvantages of large deformation and poor vibration reduction effect. The rubber pad type simplifies the internal structure and has the characteristics of small size, light weight, and easy installation. However, due to the small deformation of the rubber material, it still has the disadvantage of poor shock-isolating performance. At the same time, the rubber pad is a consumable part, resulting in poor equipment reliability and inconvenient maintenance. The vibration-damping and shock-isolating devices in the prior art are all of a single form and do not effectively combine the advantages of the two. It is necessary to make improvements.
