Chinese patent application No. 202220332152.1 discloses a building shockproof device including an upper support body, a lower support body, and a steel wire rope. The lower end face of the upper support body is provided with an upper metal plate, and the upper end face of the lower support body is provided with a lower metal plate. A middle metal plate is provided between the upper metal plate and the lower metal plate, and the upper and lower surfaces of the middle metal plate are both arranged as arc-shaped surfaces. This shockproof mechanism reduces the impact and damage of ground shaking on the building by displacement between the upper and lower support bodies. Since the horizontal displacement of this shockproof mechanism is limited and the vertical buffering capacity is weak, it cannot meet the shockproof requirements of the cabinet frame; therefore, there is an urgent need on the market for improved technologies to solve the above problems.
