A fire prevention assembly comprises a main body, a first connective unit, a tubular piece, a sensor unit, a second connective unit, a first flexible piece, a movable piece and a second flexible piece. The fire prevention assembly is installed to a fire prevention gate. In use, the sensor unit would melt at a high temperature. In such case, the tubular piece moves rearwards along with the movable piece. Therefore, the movable piece will no longer limit the movement of the position limiting plate of the fire prevention gate and the protective plates will be allowed to rotate to open or close the fire prevention gate. Consequently, the fire prevention assembly can provide protection against fires and smoke in a swift and precise manner. |
