The present invention provides a closing power reinforcing device for a door closer. The closing power reinforcing device for a door closer can remarkably reduce manufacturing costs and simplify composition thereof in comparison with an existing technique of cast molding since a device body is formed of a curved metal plate. The closing power reinforcing device for a door closer can exclude concern about an accident by rapidly closing a door when a fire breaks out, by guaranteeing smooth operability. The closing power reinforcing device comprises: a device body comprising an attachment unit attached to the inner side of the bottom of the door closer by bending a metal plate on the bottom of the door closer installed in the upper part of a door frame and the door, a guide board maintaining fixed intervals from the door closer on the outer side of the attachment unit, and a tension control plate formed in orthogonal direction to the attachment unit on the right side of the guide board; an operating unit connecting the door closer to an operating shaft of the door closer protruding from the bottom of the center of the attachment unit of the device body in order for the door closer to be operated to be closed; and a closing force generating unit installed in the tension control plate and connected to the operating unit to transmit a closing force to the door closer by the operating unit. |
