[0002] Electrical equipment refers to equipment that uses electrical energy to work or control. In order to ensure the normal operation of electrical equipment, correct grounding is a vital link. The grounding system can not only eliminate the static electricity that may accumulate in the equipment, but also effectively prevent the electrical equipment from being damaged in power failures or abnormal situations.

[0003] The stable connection of the existing grounding terminal is one of the key factors to ensure the effectiveness of the grounding function. Usually, the surface of the grounding terminal is flat, and there is a risk of loosening when it is accidentally touched, causing the equipment to lose grounding, thereby increasing the risk of failure or accident in the electrical system. For this reason, we propose an easy-to-use electrical equipment grounding structure. Utility Model Content

The adjusting rod is rotatably installed in the middle of the inner side of the grounding rod, and the outer surface of the grounding rod is evenly distributed with gears along its axial direction. The gear is meshed with the limit plate through teeth and tooth grooves, and a rotating head is fixed on the top of the adjusting rod.

[0011] Preferably, a plurality of the limiting plates are provided, and the limiting plates adjacent to each other along the height direction of the adjusting rod are perpendicular to each other.

[0012] Preferably, a groove is provided on the limiting plate.

[0013] Preferably, a wire cap is provided on the grounding rod, and a wire cap corresponding to the wire cap is connected to the outer surface of the terminal post through a threaded portion.
