Abstract

The invention relates to the technical field of sliding doors, in particular to a sliding door device. A sliding door can be conveniently closed in place, and a joint close state is ensured. The sliding door device comprises a cabinet. A guide rail is installed at the lower end of the cabinet. The sliding door is slidably installed on the guide rail through a pulley. The sliding door device is characterized in that the guide rail is a U-shaped guide groove; a notch is formed in the position, close to one side of the side wall of the cabinet, of the bottom of the U-shaped guide groove; a movable limiting block is vertically installed in the notch through a spring; when the spring is in a normal state, the limiting block is exposed to the bottom surface of the U-shaped guide groove, one end, facing towards the moving direction of the sliding door during closing, of the limiting block is a slope, and the other end is a vertical plane; when the sliding door is closed in a joint close state, the vertical plane of the limiting block is tightly clamped in the end surface of the pulley; the inner side wall of the notch is provided with a through groove; and an extension rod penetrating through the through groove of the U-shaped guide groove is installed on the lateral portion of the limiting block and is exposed to the lateral portion of the U-shaped guide groove.
