A self-locking structure includes an enclosure and a plunger assembly, where plunger assembly is movable within the enclosure in a vertical direction. An upper platform coupled to the plunger assembly, where the upper platform is configured to move in the same vertical direction as the plunger assembly. A lower platform coupled to the enclosure, where at least one isolation damper is disposed between a top surface of the lower platform and a bottom surface of the upper platform configured to compress under a load applied to a top surface of the upper platform. The plunger assembly includes a first locking finger, where the first locking finger is configured to engage with a first locking aperture of the enclosure when the at least one isolation damper is compressed under the load applied to the top surface of the upper platform.
