Quasi-zero stiffness vibration isolator suitable for dynamic scale

The invention belongs to the field of dynamic weighing, and particularly relates to a quasi-zero stiffness vibration isolator suitable for a dynamic scale. A quasi-zero stiffness vibration isolator suitable for a dynamic scale is characterized in that a vibration isolator top plate is connected with a partition plate through a supporting rod, a vibration isolator bottom plate is connected with the partition plate through a plurality of elastic steel wire ropes, the vibration isolator bottom plate is arranged on a platform through an extension part, the vibration isolator top plate is connected with the vibration isolator bottom plate through top plate stand columns on the two sides, and a disc spring is arranged on the vibration isolator bottom plate; one end of the disc spring mounting rod abuts against the disc spring, and the other end is connected with the vibration isolator top plate. The dynamic scale is arranged on the top plate, the mass of the dynamic scale directly acts on the partition plate throug
