Embodiment 1
[0045] see Figure 1-Figure 16 , the anti-buckling low-frequency vibration-isolation rubber bearing of the present invention includes a rubber bearing body 1, an upper connecting steel plate 2 arranged at the upper end of the rubber bearing body 1, and a lower connection plate arranged at the lower end of the rubber bearing body 1. The steel plate 3 and the anti-seismic sleeve 4 arranged in the rubber bearing body 1, wherein the rubber bearing body 1 includes the upper sealing layer steel plate 5, the lower sealing layer steel plate 6, and the upper sealing layer steel plate 5 and the lower sealing layer steel plate The multi-layer laminated rubber 8 between the sealing steel plates 6, wherein the laminated rubber 8 and the inner steel plate 5 are connected into one body through high-temperature vulcanization bonding; an inner steel plate is arranged between two adjacent layers of laminated rubber 8 7. The anti-seismic sleeve 4 is vertically arranged in the rubber bearing body...
Embodiment 2
[0084] see Figure 17 The difference between this embodiment and Embodiment 1 is that the rubber layer 10 is a thin rubber ring, and the thin rubber ring is set on the anti-seismic sleeve 4 .
[0085] All the other structures are implemented with reference to Example 1.
Embodiment 3
[0087] see Figure 18 The difference between this embodiment and Embodiment 1 is that one of the multiple anti-seismic sleeves 4 vertically penetrates the upper connecting steel plate 2 sequentially from the axial center of the rubber bearing body 1 , the rubber bearing body 1 and the lower connecting steel plate 3, the rubber bearing body 1 is provided with a through hole at the position in contact with the shockproof casing 4, a rubber layer 10 is arranged in the through hole, and the rubber layer 10 is implemented with reference to the rubber layer 10 in Example 1.
[0088] And other anti-seismic sleeves 4 are distributed along the circumferential direction of the rubber bearing body 1, and vertically run through the upper connecting steel plate 2, the rubber bearing body 1 and the lower connecting steel plate 3 in sequence; A through hole is provided at the contact position of the anti-seismic sleeve 4 , and a rubber layer 10 is arranged in the through hole, and the rubbe...
