Abstract: A door machine having an electric motor and a chain disk locking mechanism. The chain disk locking mechanism includes a chain disk, an engaging rotary block, a stationary shaft and a plurality of moving pins. When the chain disk is pulled to rotate, the fixed pins of the chain disk press the moving pins so as to push the engaging rotary block to rotate with the stationary shaft together. When the stationary shaft is pulled to rotate, the engaging rotary block prohibits the moving pins from rotation. When the chain disk is pulled manually, the rolling door can be rolled upward or downward; when cease pulling the chain disk, braking is immediately effected so as to prevent the rolling door from moving upward or downward. Hence, the clutch mechanism can be omitted for cost saving and the structure of the mechanism can be simplified.
