The curtain leaves 4 and the seal edges 5 are made of PVC materials.

When the door curtain folded together needs to be pulled open, the mounting plate 3 at the edge is naturally easiest to unfold, the movement of the mounting plate 3 at the edge drives the folding plate 31 on the adjacent mounting plate 3 to rotate, and the folding plate 31 directly hinged with the mounting plate 3 at the edge source is driven and directly rotated. Because of the hinge 33, as long as the rotation of the folding plate 31 is towards one side of the gap, the folding plate 31 on the same mounting plate 3 far away from the edge mounting plate 3 can not rotate, and the force can not be transferred to the subsequent mounting plate 3, thereby conveniently rotating the current mounting plate 3. Even if the rotation of the folding plate 31 is away from the opening and towards one side, only the current mounting plate 3 will produce leverage to transfer the force to the next mounting plate 3, and the next mounting plate 3 will be towards one side again due to the rotation of the folding plate 31, and the force that the user needs to provide will not be too great. Thereby facilitating the unfolding of the door curtain.

Example two: referring to fig. 6, the present embodiment is different from the first embodiment in that the slits of the adjacent mounting plates 3 are oriented differently. When the length direction of the mounting plates 3 is parallel to the supporting piece 1, the gaps on the adjacent mounting plates 3 face to opposite directions.

This arrangement enables the initial folding plate 31 to be pivoted to the slit to one side as long as the initial biasing position of the user is correct when the door curtain is unfolded. Then, the subsequent folding plate 31 can rotate towards one side of the corresponding opening, so that leverage cannot occur, and the output of a user is further reduced.

Example three: referring to fig. 7, the difference between the first embodiment and the second embodiment lies in that two opposite ends of two folding plates 31 on the same mounting plate 3 are both opened with a notch, and there are two first springs, and the two first springs are respectively mounted on two sides of the mounting plate 3. The folding plate 31 of the present embodiment can be rotated to both sides.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
