Vibration isolator inner vibration isolation ring and vibration isolation spring for floating slab track

The invention discloses a vibration isolator inner vibration isolation ring and vibration isolation spring for a floating slab track. The vibration isolator inner vibration isolation ring and vibration isolation spring comprises an inner vibration isolation spring body, an upper vibration isolation ring and a lower vibration isolation ring; a first connecting plate is welded to the top end of theinner vibration isolation spring body, and the upper vibration isolation ring body is bonded to the periphery of the upper end of the first connecting plate; and a second connecting plate is welded tothe bottom end of the inner vibration isolation spring body, and the lower vibration isolation ring is bonded to the periphery of the bottom end of the second connecting plate. The vibration isolatorinner vibration isolation ring and vibration isolation spring has the following beneficial effects that through the design of the upper vibration isolation ring of the butterfly-shaped structure andthe lower vibration isolatio
