The utility model provides a testing device for detecting the shock resistance of an electric meter box. A mechanical steel frame of the testing device is fixed on a foundation bottom plate by steel columns respectively arranged at the two sides of the mechanism steel frame; the central part of a board at the upper part of the mechanism steel frame is provided with a lifting and releasing mechanism connected with a control device; the lifting and releasing mechanism is internally provided with a traction electromagnet which can ascent and descent; the center of the board at the upper part of the mechanism steel frame is provided with a center hole aligned with the traction electromagnet; a blocking groove is arranged on the foundation bottom plate corresponding to the center hole. The testing device has the effects that a device used for carrying out quantitative evaluation on the shock resistance of the existing electric meter box established, so that shells of the electric meter boxes with different specifications can be conveniently measured; data is acquired by linking a mechanical structure system and a control and sensing system, drop hammer damage is carried out on the electric meter box by a finite element analysis method, and the results are analyzed, so that the main stress distribution of the electric meter box can be obtained, and guarantee is provided for rapidly evaluating the shock resistance of the electric meter box.
