<p>The present invention relates to a fixing device for three sliding doors. The fixing device for three sliding doors interlocks a front door, a middle door, and a rear door, which are installed to be overlapped in a sliding method in the lower part of the upper rail installed in the door frame of a building, to be opened and closed. The upper rail includes a second guiding unit. The second guiding unit is formed in the longitudinal direction of the installation plate unit on the front surface of the lower part of the installation plate unit fixed to and installed in the upper part of the door frame. A front door is installed to be moved in the longitudinal direction of the installation plate unit in the second guiding unit. The second guiding unit has a door fixing unit for maintaining the closing of the front door by allowing the front door not to be separated from the door frame when the front door moving along the second guiding unit approaches the door frame and is closed. The door fixing unit includes a fixing unit installed in the second guiding unit of the upper rail; a moving object installed to be moved along the second guiding unit; and an attaching piece which keeps the front door to be closed by being in contact with the fixing unit by magnetism by being fixed and attached to the moving object when the front door approaches the door frame and is closed.</p> |
