Referring to fig. 1 to 6, the windproof roller blind according to the embodiment of the present invention includes two end caps 10, two side rails, a protective cover 40 and a protective cover 50, wherein the side rails are respectively disposed under the end caps 10, and the zipper on the side of the fabric slides along the side rails. The two ends of the protective cover 40 are respectively arranged on the end covers 10, the protective cover 50 is fixed on the protective cover 40, a space for installing the winding drum is formed between the protective cover 40 and the protective cover 50, the winding drum is arranged in the space, and the two ends of the winding drum are respectively rotatably arranged on the end covers 10. A supporting plate 60 is arranged in the protecting cover 50, a fabric passage capable of allowing fabric to pass through is formed between the supporting plate 60 and the inner side of the protecting cover 40, and the fabric passage is opposite to the inlets of the side rails. The length of backup pad 60 is arranged along the length direction of guard shield 50, and when the reel rotated, when the surface fabric was put down or was rewound from the reel, backup pad 60 was supporting the monoblock surface fabric that is about to get into the surface fabric passageway, guaranteed that the surface fabric is whole can get into the surface fabric passageway with the direction parallel with the surface fabric passageway to make the surface fabric be difficult for taking place the skew when the motion, the surface fabric is level and smooth all the time. Alternatively, the top surface of the support plate 60 is arc-shaped, and when the fabric is completely wound on the drum, the outer side of the fabric on the drum can abut against the support plate 60.

In some embodiments, the end cap 10 is provided with a stop 70 opposite the support plate 60, the stop 70 being located on the inside of the shield 40, the stop 70 and the support plate 60 forming a fabric side channel therebetween, the side of the fabric being guided by the fabric side channel and then oriented into the side rails. The width of the fabric side channel refers to the distance between the stopper 70 and the support plate 60 in the same horizontal direction. The width of the inlet of the fabric side channel is larger than the width of the outlet of the fabric side channel, so that the side edge of the fabric can conveniently enter the fabric side channel.

Further, referring to fig. 3, a sinking platform 701 is arranged on one side of the stopper 70 close to the fabric side channel, the diameter of the sinking platform 701 and the diameter of the supporting plate 60 form a channel for allowing the zipper to pass through the zipper, and the arrangement of the sinking platform 701 can effectively avoid the zipper due to the fact that the zipper is thicker than the fabric, so that the zipper can slide in the zipper channel with the width larger than the fabric side channel and enter the side rails. Likewise, the width of the zipper channel refers to the spacing between the sinker stage 701 and the supporting plate 60 in the same horizontal direction. Optionally, the zipper channel has an entrance width greater than an exit width of the zipper channel to facilitate introduction of the zipper of the fabric into the zipper channel.

In some embodiments, referring to FIG. 5, the lowering of the fabric is illustrated as more fabric is being wound onto the drum. When the fabric is transferred, the included angle between the movement direction of the fabric and the direction of the fabric channel is large, so that large friction is easily generated between the fabric and the fabric channel to destroy the smoothness of the downward movement of the fabric. In order to slow down the angle change of the fabric entering the fabric channel when the fabric is put down and enable the fabric to enter the fabric channel more smoothly, a supporting seat 402 is arranged on the inner side of the protective cover 40, the supporting seat 402 is located above the fabric channel, and the supporting surface of the supporting seat 402 is inclined gradually towards the protective cover 50 from top to bottom. In the embodiment, the supporting surface refers to the surface of the supporting base 402 which is connected with the fabric. When the fabric is placed downwards, the fabric can enter the fabric channel more smoothly under the supporting action of the supporting seat 402, and the friction between the fabric and the fabric channel is reduced. The same principle is used for rewinding the fabric.
