The utility model relates to the technical field of vibration isolation platforms, and provides a passive vibration isolation platform. The passive vibration isolation platform comprises a top plate, a bottom plate and a vibration isolation device which is arranged between the top plate and the bottom plate, wherein the vibration isolation device comprises an upper guide rail mechanism, a lower guide rail mechanism and an X-shaped connecting rod mechanism; the upper guide rail mechanism is arranged on the top plate; the lower guide rail mechanism is arranged on the bottom plate and corresponds to the upper guide rail mechanism; the X-shaped connecting rod mechanism is movably connected between the upper guide rail mechanism and the lower guide rail mechanism, is folded and retracted under pressure and comprises at least two groups of parallel connecting rod rows; the top end parts of each group of connecting rod rows are connected with the upper guide rail mechanism, and the bottom end parts of each group of connecting rod rows are connected with the lower guide rail mechanism; at least two groups of connecting rod rows are provided with corresponding hinge positions; the X-shaped connecting rod mechanism also comprises guide rods which are hinged to the corresponding hinge positions of at least two groups of connecting rod rows; elastic elements are connected between the guide rods. Compared with the prior art, the passive vibration isolation platform has the advantages of good bearing capacity and stability. |
