Abstract
The utility model discloses a rotary grounding conductive device for welding. The rotary grounding conductive device comprises a rotary conductive shaft and a conductor. The conductor comprises a conductive sleeve arranged transversely and an upright rod arranged longitudinally. The conductor is of a T-shaped structure integrally. A through hole used for being connected with a grounding cable is arranged at the lower of the upright rod. A through shaft hole is transversely arranged on the conductive sleeve. A sealing cap is detachably connected to the right end of the conductive sleeve. The rotary conductive shaft is rotatably arranged in the shaft hole. A clamp spring is arranged at the right end of the rotary conductive shaft, while the left end of the rotary conductive shaft extends out of the conductive sleeve and is provided with a connecting through hole. The rotary grounding conductive device is simple in structure and easy to implement. The conductor is of the T-shaped structure and can keep still owing to eccentricity when the rotary conductive shaft rotates, so that the cable cannot be twined. In addition, the rotary conductive shaft, the conductor, and the sealing cap are made of copper materials and are good in conductivity. Besides, the rotary conductive shaft fittingly rubs with the conductor, and conductive paste is arranged on contact surfaces of the rotary conductive shaft and the conductor, so that contact resistance is effectively reduced, and the rotary grounding conductive device is good in conductivity.
