Embodiment Construction
[0029] The present invention will be further described in detail below with reference to the drawings and specific embodiments.
[0030] Such as figure 1 As shown, a compression spring type six-degree-of-freedom quasi-zero stiffness vibration isolator of the present invention includes an outer frame 1, a vibration-isolated box 2, and 6 isolators distributed on six surfaces of the vibration-isolated box 2. Vibration module 3. The outer frame 1 is fixed to the foundation. When the foundation vibrates, the frame 1 will vibrate. Objects that need vibration isolation are installed in the vibration isolation box 2. The bottom of the vibration isolation module 3 is fixed through the frame 3.1 and the outer frame 1, and the other end is connected to the vibration isolation box 2 through a connecting piece 3.2.
[0031] Such as figure 2 As shown, the vibration isolation module 3 consists of a frame 3.1, a connector 3.2, a vertical compression spring 3.3, and four lateral compression spr...
