With the above arrangement, the hanging mechanism 200 can push the curtain 30 on the guide 20 by moving along the guide 20, so that the curtain 30 moves along the guide 20; the second hooking component 230 is moved along the width direction of the mounting base 210, and the distance between the second hooking component 230 and the first hooking component 220 in the width direction of the guide 20 can be adjusted to adapt to the guide 20 with different widths or the bent guide 20, so that the application range of the curtain opening and closing device 10 is expanded, and the adaptability is wider.

It should be noted that, one side of the curtain 30 is provided with a plurality of through holes or hanging rings (not shown in the figures), and the guide 20 is inserted through the through holes or hanging rings, so that the curtain 30 is hung on the guide 20. The hanging mechanism 200 is hung on the guide 20 and located between the two through holes or the two hanging rings, when the host 100 drives the hanging mechanism 200 to move along the guide 20, the hanging mechanism 200 moves along the guide 20 and pushes against the curtain 30 on the guide 20 to push the curtain 30 to move along the guide 20, thereby realizing the automatic opening and closing of the curtain 30.

It should be noted that the curved guide member 20 is understood that the guide member 20 has a U-shape, an S-shape or other shapes with corners.

Specifically, in the present embodiment, referring to fig. 2, a guide groove 21 and an opening communicating with the guide groove 21 are provided in the guide 20, the opening penetrates through the bottom wall of the guide 20 to form a first projecting arm 22 and a second projecting arm 23, and the cross section of the guide 20 is U-shaped. Thus, the first hooking member 220 is movably mounted to the first projecting arm 22, and the second hooking member 230 is movably mounted to the second projecting arm 23.

Here, the guide member 20 may be a single-body structure or a split structure, and the guide member 20 may be a straight line type, an S-type, or other irregular shape as a whole.

In this embodiment, referring to fig. 3 and 4, the hanging mechanism 200 further includes a movable block 233, the second hanging component 230 is fixed to the movable block 233, and the movable block 233 is movably disposed on the mounting base 210 along the width direction of the mounting base 210.

It will be appreciated that the second leg 232b extends through the opening in the guide member 20 and is fixedly attached to the mounting block 210. When the host 100 drives the hitching mechanism 200 to move along the guide member 20, the second moving member 231 rolls relative to the second projecting arm 23, and the second sleeve 234 can rotate along the edge of the opening of the guide member 20, thereby preventing the second vertical rod 232b from hard friction wear with the opening of the guide member 20 and ensuring the smoothness of the movement of the second moving member 231.

In this embodiment, the outer diameter of the second sleeve 234 is smaller than the opening width of the guide 20, and the second sleeve 234 is hollow and has a smooth surface, which is beneficial to reducing the friction between the second sleeve 234 and the opening edge of the guide 20.
