In the process of the rolling curtain 12 rubbing against the pressing roller 45, the pressing roller 45 rotates automatically, so that the sliding friction between the rolling curtain 12 and the pressing plate 42 is converted into rolling friction, and the friction force between the pressing plate 42 and the rolling curtain 12 is reduced, so that the rolling curtain 12 is prevented from being worn by the pressing plate 42.

Meanwhile, the roller shutter 12 drives the pressing plate 42 to roll, the reciprocating screw rod 46 limits the moving direction of the pressing roller 47 when the pressing roller 47 rolls, so that the pressing roller 47 reciprocates along the reciprocating screw rod 46, the roller shutter 12 is conveniently rolled in a reciprocating mode by the pressing roller 47, the rolling flatness of the roller shutter 12 is further improved, and the possibility of folding damage of the roller shutter 12 is reduced.

The implementation principle of the outer sunshade integrated system casement window of the embodiment of the application is as follows: in the process of winding the roller blind 12, an operator starts the servo motor 18, and the servo motor 18 drives the winding roller 13 to rotate, so that the winding roller 13 winds the roller blind 12. At this time, the limiting disc 2 limits the moving direction of the roller shutter 12, so that the rolling regularity of the roller shutter 12 is increased. Meanwhile, the abutting spring 44 pushes the pressing plate 42 to abut the abutting roller 45 against the roller shutter 12, so that the abutting roller 45 applies pressure to the roller shutter 12, the possibility of tilting of the roller shutter 12 in the rolling process can be reduced, and the flatness of the roller shutter 12 in the rolling process can be further improved. And the press roller 47 reciprocates along the reciprocating screw rod 46 to roll the roller shutter 12 back and forth, further increasing the flatness of the roller shutter 12.

When the rolling curtain 12 is abutted against the limiting rod 31, the rolling curtain 12 pushes the limiting rod 31 to be separated from the limiting disc 2, and at the moment, the tension spring 32 pulls the limiting rod 31 to be separated from the limiting hole 202. Then, the pushing spring 23 pushes the limiting plate 22 to extend out of the limiting groove 201, and the return spring 26 pushes the mounting plate 25 to move to one side of the bottom wall of the raw material mounting groove 222 until the fixture block 28 is embedded in the fixture groove 223, so as to fix the mounting plate 25, so that the surface of the mounting plate 25 far away from the bottom wall of the mounting groove 222 is flush with the surface of the limiting disc 2, and further limiting is performed on the roller shutter 12.

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