The invention relates to conveyor belts, and especially relates to a safety conveyor belt. Through the arrangement of supporting rods, supporting members, a connecting rope and a limit switch, the connecting rope can be connected to the limit switch through the supporting rods and the supporting member, so that the limit switch stroke can be triggered to make the conveyor belt suddenly stop by pulling the connecting rope when people are caught in a conveyor belt, and therefore, on-site stop can be realized, and injuries can be prevented from aggravating. The safety conveyor belt includes the conveyor belt, a support and a control cabinet; the conveyor belt is installed on the support; the starting and stopping of the conveyor belt can be controlled by the control cabinet; the support is provided with multiple vertical supporting rods along the running direction of the conveyor belt in an interval manner; the supporting rods are connected to the supporting members; the connecting rope is arranged, one end of the connecting rope is connected to the supporting rods on the starting side, and the other end of the connecting rope is connected to the contact machinery of the limit switch;and the limit switch is connected to the control cabinet through a lead, and the sudden stop of the conveyor belt can be realized after the limit switch is triggered.
