The invention relates to a vibration isolation and buffer device for machine-born equipment, in particular to a totally-closed rigidity adjustable type vibration isolator, which comprises a casing, an installation core shaft, a protective rubber cover, an upper rubber ring, a spherical vibration isolation part and a lower rubber ring. The casing is of a sealed structure, the top of the casing is provided with an installation hole where the installation core shaft is arranged, and the spherical vibration isolation part is arranged in the sealed casing and is connected with the bottom of the installation core shaft together. The upper rubber ring is sleeved at the upper portion of a damp rubber ball, and the lower rubber ring is sleeved at the lower portion of the damp rubber ball which is sealed in the casing. The totally-closed rigidity adjustable type vibration isolator adopts a totally-closed structure to have small environment influence, utilizes a combination structure combining the spherical surface and the cylindrical surface to improve vibration isolation and retarding effects, utilizes the structures of the upper rubber ring and the lower rubber ring to limit the swinging of the head of the installation core shaft and improve using safety, and can be suitable for different frequency ranges by rotating the upper cover to adjust the rigidity of the vibration isolator.
