Safety device for curtain controller
A safety device for a curtain controller is provided. The safety device comprises a base, a bead chain wheel, and a cover. A shaft sleeve having a conical shape is disposed in a through hole of the base to connect a shaft's terminal and thus be fixed in a sleeving hole, having a shape to fit the shaft sleeve, of the bead chain wheel, so that the motions of the shaft sleeve and the bead chain wheel are linked. A bead chain is wound on the bead chain wheel. When the bead chain is pulled down, the shaft sleeve can drive the rotation of the bead chain wheel. The upper part of the cover is pivotally connected to the base, and the lower part of the cover buckles the base. Therefore, when the bead chain is instantly pulled down, the cover can be opened to drop the bead chain wheel.
