Door operator having lock mechanism
A door operator comprising a chain disk, a rotary shaft, and a locking mechanism. The chain disk is configured to rotate the rotary shaft, and the locking mechanism is adapted to lock the rotary shaft. The locking mechanism comprises an end disc, an outer ring portion, a plurality of push pins, a bidirectional rotary block, a plurality of anti-rotation posts, and a plurality of springs. The end disc is connected to the chain disk. The end disc includes an axial hole at the center, and a positioning ring at one end face thereof. The outer ring portion has one end positioned in the positioning ring, and defines a central receiving portion with the end disc. The plurality of push pins are axially arranged along the inner circumference of the central receiving portion, and are equidistantly spaced from each other. The plurality of push pins is secured on the end disk at one end. A bidirectional rotary block is received in the central receiving portion and fixedly connected to the rotary shaft. The rotary shaft has one end pivoted in the axial hole. N
