[0016] The present invention provides a voltage impact resistance test device. Compared with the prior art, it has the following beneficial effects:

[0017] 1. The voltage withstand impulse test device realizes the function of fixing the main body of the impulse withstand voltage tester of different sizes by arranging a rotating plate, an adjusting rod, a first connecting plate, a fixed plate, a movable plate, a rotating shaft, a turntable, a fixed frame and a slide groove, and fixes the main body of the impulse withstand voltage tester on the top of the mounting plate to prevent the main body of the impulse withstand voltage tester from shaking during transportation so that the internal components of the main body of the impulse withstand voltage tester are damaged.

[0018] 2. The voltage impact test device realizes the function of preventing the rotating shaft from reversing and loosening the fixation to the main body of the impact voltage withstand tester by arranging a mounting frame, a fixing sleeve, a ratchet, a pawl, a first spring, a second clamping hole, a fixing block, a second clamping hole, a second clamping block, a third spring and a second connecting frame. The rotating shaft rotates while driving the ratchet and the fixing sleeve to rotate. The fixing sleeve rotates along the inside of the mounting frame. The ratchet rotates while squeezing the pawl. The pawl continuously moves with one end of the first spring. When the first spring loses its pulling force, the pawl returns to its original position under the action of the elastic force and is stuck on one side of the ratchet, preventing the ratchet and the rotating shaft from reversing and loosening the fixation to the main body of the impact voltage withstand tester.

[0019] 3.

When the mounting plate moves, the moving block is moved on the outside of the first slide bar through the connecting rod. The moving block moves to squeeze the second spring. The second spring is squeezed to generate elastic force, which buffers the vibration again to prevent the main body of the voltage-withstand impact tester from being damaged during transportation.

[0020] 4. The voltage impact test device realizes the function of dissipating heat for the main body of the impact voltage withstand tester by setting cooling fins, connection holes, connection boxes and fans, so as to better discharge the heat generated during the operation of the main body of the impact voltage withstand tester. Under the action of the fan, the outside gas enters the connection box through the connection holes, and the original gas in the connection box is pumped to the outside by the fan, so as to further dissipate heat for the main body of the impact voltage withstand tester, thereby preventing the equipment from being damaged or causing safety hazards due to overheating.
