Abstract
The utility model relates to a drive unit of a door machine, which comprises an electrical motor arranged in the body case of the drive unit. The output shaft of the electrical motor is connected with a retarding mechanism, the output shaft of which is connected with a gear and the gear can drive the drive unit to move on a fixed chain. The body case of the drive unit is provided with a hanging hole which is used for driving a door plate to move up and down. A clutch mechanism is arranged between the output shaft of the retarding mechanism and the gear. The clutch mechanism comprises an engaging and disengaging hole which is arranged on the gear, and an engaging and disengaging block is provided with an engaging and disengaging pin which is cooperated with the engaging and disengaging hole. An engaging and disengaging draw rod can press and make the engaging and disengaging pin fall off the engaging and disengaging hole, and the engaging and disengaging draw rod is connected with a positioning piece and a pull handle, the positioning piece can position the engaging and disengaging draw rod and the engaging and disengaging block is provided with a reset spring. Because the clutch mechanism is arranged between the output shaft of the retarding mechanism and the gear, the door machine has power-off self-locking function.
