Detailed Description

The invention is further described with reference to the following figures and embodiments:

as shown in fig. 1, a pleated curtain includes an upper frame 11, a lower frame 12, and a curtain surface 21 between the upper frame 11 and the lower frame 12. The curtain is characterized by further comprising side frames (not shown in the figure, the same below), wherein the side frames are respectively connected with the upper frame 11 and the lower frame 12 in a buckling mode, and the curtain surface 21 slides up and down along tracks in the side frames.

The curtain surface 21 is provided with a plurality of rows of through holes 22, and the through holes 22 in the same row are vertically corresponding to each other. The pulling rope 30 passes through the through hole 22 and the upper frame 11 and the lower frame 12 to form a ring around, so that the connection between the pulling rope 30 and the pleated curtain is stable, and the tidiness of the whole structure is ensured.

The curtain surface 21 comprises a PET white film layer, a PET black film layer and a PET non-woven fabric layer from outside to inside, and the effects of shading, high temperature resistance and ultraviolet resistance of the pleated curtain are achieved.

Preferably, the PET black film layer is plated with an aluminum film, and the aluminum film is positioned between the PET black film layer and the PET non-woven fabric layer to increase the sun-shading effect of the product. Preferably, a PE film is arranged between the PET white film layer and the PET black film layer, the PET white film layer and the PET black film layer are compounded through hot melting of the PE film at 105 ℃, the sun-shading effect of the whole curtain face is guaranteed, and meanwhile the hand feeling and hardness of the curtain face are better.

Preferably, a rope winding mechanism is arranged in the upper frame 11, and the rope winding mechanism can realize manual rope winding or electric rope winding. Specifically, the method comprises the following steps: the rope winding mechanism is a rope winding wheel, and the pull rope 30 is manually pulled to drive the lower frame 12 and the curtain surface 21 to be folded after the pull rope 30 winds around the rope winding wheel; or the rope rolling mechanism comprises a motor and a rope rolling component, and the rope rolling mechanism is controlled remotely so as to drive the lower frame 12 and the curtain surface 21 to be folded through the rope rolling component.

Example one

As shown in fig. 2 and 3, the curtain surface 21 is folded into a pleated shape, and one side of the folding position of the curtain surface 21 is heat-pressed to form a first folding portion 212 so that the cross section of the curtain surface 21 is Y-shaped.

In this embodiment, two layers of oppositely bent extending portions 211 are disposed between the upper and lower layers of first folding portions 212, and the through holes 22 are disposed on the extending portions 211 of each layer.

Preferably, the total width of the first folding portion 212 is smaller than the total width of the non-heat-pressed portion (i.e., the extending portion), so that the light-shielding and sound-insulating effects of the product can be ensured, the supporting performance of the folding portion of the product can be ensured, and the consumption of excessive raw materials can be avoided.
