The invention relates to an anti-releasing upper sill structure applied to an elevator door. The structure comprises an upper sill frame body, wherein the upper sill frame body comprises a right-angled edge, an upper section, an upper guide rail and a lower guide rail which are symmetrically bent, and an extension section; a vertical edge of the right-angled edge downwards extends to the upper section; the upper section extends downwards to the upper guide rail; the upper guide rail extends and is connected with the lower guide rail via a vertical edge; the lower guide rail extends downwards to the extension section; the upper section and the extension section are in one vertical surface; the upper guide rail consists of a first notch downwards projected and a first convex port upwards projected; the lower guide rail consists of a second notch downwards projected and a second convex port upwards projected; the inner diameters of circular arcs of the first notch and the second convex port are 4-4.4 mm; and the inner diameters of the first convex port and the second notch are 2.7-3 mm. The structure is applied to the elevator door device; the upper sill frame is connected and matched with a door hanging wheel and a pressing wheel on a hanging plate component, so that the technical problem of weak connecting safety between the upper sill frame and a mechanical hook of a hanging plate is solved; and when the elevator door is collided by external force, a door cannot shake, the mechanical releasing prevention is achieved, and the working stability of the whole elevator door device is promoted.
