The invention discloses a clockwork spring type elevator landing door self-closing device. The clockwork spring type elevator landing door self-closing device comprises a left landing door hanging plate and a right landing door hanging plate which are arranged on an elevator landing door head in a sliding mode. The linkage mechanism is used for linking the left landing door hanging plate and the right landing door hanging plate; the linkage mechanism comprises a first pulley, a second pulley, a linkage steel wire rope, a linkage steel wire rope end connecting device, a linkage steel wire rope tensioning spring and a clockwork spring; the first pulley and the second pulley are respectively arranged at the left and right ends of the landing door head; the clockwork spring is arranged on the first pulley and/or the second pulley or the landing door head; one end of the linkage steel wire rope is connected with the right landing door hanging plate through a linkage steel wire rope tensioning spring; the other end of the linkage steel wire rope is connected with a right landing door hanging plate through a linkage steel wire rope end connecting device; the elevator landing door self-closing device is compact in structure, capable of providing stable and reliable self-closing force for an elevator landing door, small in occupied space, beneficial to overall thinning of a landing door system and saving of elevator shaft space, simple in structure, few and small in parts and low in cost.
