The rigidity-adjustable low-frequency vibration isolation device comprises an upper supporting platform, a rubber supporting structure, a base, a center shaft and a vibration isolator, the upper supporting platform is located at the top of the rubber supporting structure, the interior of the rubber supporting structure is vertically through, and the bottom of the rubber supporting structure is connected with the base; a cavity is defined by the bottom face of the upper supporting platform, the inner wall face of the rubber supporting structure and the upper surface of the base. The center shaft and the vibration isolator are installed in the cavity, the upper end of the center shaft is connected with the bottom of the upper supporting platform through a locking nut 7, and the lower end of the center shaft is connected with the bottom of the vibration isolator. The vibration isolation device has the beneficial effects that on the basis of the positive and negative stiffness parallel connection principle, the r
