The utility model discloses an anti-rolling wire coil which comprises a winding post, rolling discs are fixed at the two ends of the winding post, guide blocks are fixed on the surfaces of the rolling discs, anti-rolling frames are arranged in the guide blocks in a sliding mode, the anti-rolling frames can slide in the length direction of the guide blocks, and driving structures are arranged in the centers of the rolling discs. Wherein the anti-rolling frame is connected with the driving structure, and under the action of the driving structure, the anti-rolling frame can extend out of the edge of the rolling disc. According to the wire coil, through the arranged anti-rolling frame, when the wire coil does not need to be transferred in a rolling mode or unwound, the driving arms can be driven by the driving structure to swing, the sliding part slides in the length direction of the guide block in the swinging process, and the anti-rolling part moves to the periphery of the rolling disc; in this way, a triangular supporting structure can be formed in the circumferential direction of the rolling disc, when the wire coil rolls, the wire coil can be hindered by the supporting effect of the anti-rolling part, and the safety of the wire coil in the placing state is guaranteed.
