Therefore, the guide rod 40 and the guide sleeve 50 can be utilized to limit the disc spring 14 in the horizontal direction, so that the disc spring 14 is easily compressed in the vertical direction, and meanwhile, the axial alignment of a plurality of disc springs 14 can be ensured all the time, and the vertical vibration isolation device 10 has larger vertical bearing capacity and smaller vertical rigidity.

Therefore, the horizontal deformation of the coil spring 13 can be limited by the inner guide rod 70, so that the coil spring 13 is easily compressed in the vertical direction, and the transverse instability of the coil spring 13 under the action of larger vertical pressure can be avoided, so that the vertical vibration isolation device 10 has larger vertical bearing capacity and smaller vertical rigidity.
Advantageously, the vertical vibration isolation devices 10 are arranged in plurality and spaced apart in the horizontal direction as shown in the figure. The guide rods 40 and the guide sleeves 50 are both multiple, the guide rods 40 are matched in the guide sleeves 50 in a one-to-one correspondence mode, the vertical vibration isolation device 10 comprises multiple disk springs 14 which are overlapped in the vertical direction, the vertical vibration isolation devices 10 are sleeved outside the guide sleeves 50 in a one-to-one correspondence mode, or the vertical vibration isolation devices 10 comprise spiral springs 13 and are arranged outside the guide sleeves 50 or in the guide rods 40 in a one-to-one correspondence mode.
