[0007] The upper part of the side door frame 1 is fixedly connected to the slide plate 1 by bolts, the lower part of the side door frame is fixedly connected to the slide plate 2 by bolts, the middle part of the side door frame 2 is fixedly connected to the slider 3, the inward sliding door panel is fixedly connected to the slide plate 3 movable by the slider 3 near the side door frame 2, the upper and lower parts of the inward sliding door panel near the side door frame are hinged to the pulley 1 and the pulley 2 movable on the inner sides of the slide plate 1 and the slide plate 2 respectively, and the lower part of the outer surface of the inward sliding door panel is provided with a hand placement groove.

[0008] As a further improvement, the lower surface of the upper door panel is inclined slope one, and the upper surface of the inward sliding door panel is inclined slope two adapted to the inclined slope one.

[0009] As a further improvement, the slider three is on the same horizontal plane as the lower surface of the upper door panel.

[0010] As a further improvement, the bottom end of the slide plate one, the bottom end of the slide plate two and the top end of the slide plate three are all arc-shaped corner structures, and the slide plate one and the slide plate two are not on the same vertical line, that is, the slide plate one and the slide plate two are adjacent.

[0011] The beneficial effects of the utility model are:

[0012] The structure is simple. The door is opened by pushing the inward sliding door panel to move upward along the slide plate one and the slide plate two, and the slide plate three moves upward together. There is no sanitary dead corner on the bottom surface and the noise is small. BRIEF DESCRIPTION OF THE DRAWINGS
