The movable block 46 moves in the opposite direction through the inclined surface 440 of the second slide rail 44, thereby driving the second roller 320 to move in the opposite direction, and the coil spring 61 also rotates in the opposite direction to loosen. The pressing force of the movable block 46 pulling downwards gradually decreases; then, as shown in FIG. 5, the movable block 46 moves below the first swing rod 41, hits the free end of the first swing rod 41, and finally passes over the first swing rod. 41 returns to the original position.

The movable block 46 slides back and forth from the first swing rod 41, the second swing rod 42 and the second slide rail 44 in sequence to realize the functions of semi-automatic door opening and automatic door closing; Impact, this embodiment is also provided with a buffering member 7, as shown in Figures 1 and 2, the buffering member 7 is mounted on the first roller seat 311; the buffering member 7 includes a housing 71, a push rod 72 and a second An elastic body (not shown in the figure), the second elastic body (not shown in the figure) and the push rod 72 are mounted on the housing 71, and two of the second elastic body (not shown in the figure) The ends act on the inner wall of the housing and one end of the push rod 72 respectively; wherein the buffer member 7 moves in the reverse direction with the pulley assembly 3 to drive the other end of the push rod 72 against the side wall of the frame 2.

Furthermore, if the door needs to be opened for a long time, the sliding door can be restricted to the open state. When in use, only a limit slot 8 is provided on the first slide rail 20 and/or the second slide rail 44, such as As shown in Figures 1 and 2, the limiting groove 8 is used for the second roller 320 and/or the movable block 46 of the pulley assembly 3 to be placed in the limiting position, that is, a limit can be provided on the second slide rail 44 Position slot 8, and the limit slot 8 is located between the edge of the second swing rod 42 and the maximum door opening position, so that the door body 1 can be moved by human hands, so that the movable block 46 enters the limit slot 8 and the movable block 46 remains It is positioned in the limit slot 8 to keep the door open all the time; and the limit slot 8 is opened between the edge of the second swing lever 42 and the maximum opening position for semi-automatic opening and closing when it is not the limit slot 8. The function can be used normally. In this embodiment, the limiting groove 8 is a groove provided on the inclined surface 440 of the second slide rail 44, which can accommodate the movable block 46 and restrict the movement of the movable block 46.
