Protection mechanism for insulation monitoring device

The utility model discloses a protection mechanism for an insulation monitoring device in the technical field of monitoring device protection mechanisms, which comprises a monitoring body assembly and a protection assembly, the monitoring body assembly comprises a bottom plate, a monitoring box is fixed at the top of the bottom plate, a mounting block is fixed at the top of the monitoring box, and the protection assembly comprises a support frame. And the bottom of the supporting frame is fixedly connected with the bottom plate, a rotating rod penetrates through the interior of the supporting frame, and the two ends of the rotating rod are connected with force reducing wheels correspondingly. When the top of the absorption frame and the top of the balance plate are impacted by downward external force, the top surface of the absorption frame is an arc-shaped surface, the absorption frame with the arc-shaped surface can prevent an object generating impact from staying at the top of the device, the impacted abso
