The invention discloses a slide bar type tensile limiting-displacement vibration isolation support which comprises a vibration isolation rubber pad, an upper steel sheet and a lower steel sheet. The upper steel sheet and the lower steel sheet are anchored to an upper structure and a lower structure. The slide bar type tensile limiting-displacement vibration isolation support is characterized in that the two sides or the periphery of the bottom of the upper steel plate are/is symmetrically provided with slide bars and tensile limiting-displacement mechanisms composed of pull rods and sleeves, wherein the pull rods are provided with sliding grooves; the slide bars are fixedly connected with the upper steel sheet, the sleeves are anchored to the lower structure through bases, and the slide bars are circular rod pieces arranged on a vertical plate; the sliding grooves are clamp grooves formed in one ends of the pull rods and matched with the slide bars, and the sliding grooves are formed in the slide bars in a sleeving mode and connected with the slide bars in a sliding mode. Compared with the prior art, the slide bar type tensile limiting-displacement vibration isolation support is simple in structure and high in horizontal shearing resistance and vertical tensile deformation resistance, the stability of the support is greatly improved, the problems of toppling and ultralimit of tensile stress of the vibration isolation support possibly generated by vibration isolation of a high-rise building are well solved, and the slide bar type tensile limiting-displacement vibration isolation support is especially suitable for application and popularization of laminated rubber vibration isolation supports of high-rise buildings in earthquake regions of high earthquake intensity.
