The invention provides a centrifugal speed control door closing device. The centrifugal speed control door closing device comprises a first connecting rod hinged with a door body frame, a second connecting rod hinged with the end part of the first connecting rod, and a fixed frame, wherein the fixed frame is mounted on a door body, and consists of a copper column and three pieces of organic glass; the three pieces of organic glass are supported by the copper column to form two sandwich layers; the end part of the second connecting rod is fixedly connected with the end part of a shaft 1; the shaft 1 vertically penetrates through the two sandwich layers to be mounted among the three pieces of organic glass; a first gear and a torsion spring energy storage mechanism are mounted on the shaft 1; a shaft 2 is mounted in the lower sandwich layer; a second gear is mounted on the shaft 2; a rotating shaft is mounted among the three pieces of organic glass, and penetrates through the two sandwich layers; a third gear and a damping deceleration mechanism are mounted on the rotating shaft; and the second gear is synchronously engaged with the first gear and the third gear. The centrifugal speed control door closing device is convenient for installation and long in service life.
