The elevator ceiling structure of claim 5, wherein: one end lower surface of the mild steel plate (241) far away from the rotating shaft (25) is fixedly connected with a limiting block (242) which can protrude out of the lower side of the access hole (23) and can abut against one end, close to the rotating shaft (25), of the access hole (23).

7. The elevator ceiling structure of claim 6, wherein: the one end that pivot (25) were kept away from in mild steel board (241) has seted up the screw, the one end rigid coupling that pivot (25) were kept away from in roof (2) upper surface correspondence access hole (23) has the locating plate, is close to the vertical bolt (28) of inserting of one end of access hole (23) is equipped with upper end can threaded connection in the screw.
