[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention pertains. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] Combine the following Figures 1 to 7 It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0041] It should be noted that in the embodiment of the present invention, the "up" direction is the positive direction of the first direction, the "down" direction is the negative direction of the first direction, the "left" direction is the negative direction of the second direction, the "right" direction is the positive direction of the second direction, the "front" direction is the positive direction of the third direction, and the "backward" direction is the negative direction of the third direction.

[0042] See also Figures 1 to 7 An embodiment of the utility model provides a windproof rolling curtain, which includes a curtain body 100, a winding mechanism 200, a track 300 and a limiting member 400.

[0043] Among them, the winding mechanism 200 includes a roller 210, which can wind up or unfold the curtain body 100. When the roller 210 rotates forward, the curtain body 100 moves upward and the curtain body 100 is wound; when the roller 210 rotates reversely, the curtain body 100 moves downward and the curtain body is unfolded.

[0044] The track 300 is slidably connected to both sides of the curtain body 100, and can guide the curtain body 100 to slide in the first direction, that is, the curtain body 100 can move in the up and down directions along the track 300. For example, the first track 310 is slidably connected to the first side of the curtain body 100, and the second track 320 is slidably connected to the second side of the curtain body 100.

[0045] The limiting members 400 are disposed on both sides of the curtain body 100 and extend along the length direction of the curtain body 100 , that is, the limiting members 400 extend along the first direction, and the limiting members 400 are slidably connected to the track 300 .

[0046] The limiting member 400 is in the form of a sheet, and the first section of the limiting member 400 is clamped in the track 300 and forms an angle with the curtain body 100, which can limit the curtain body 100 from leaving the track 300 along the second direction, that is, the curtain body 100 is restricted to move in the left and right directions under the action of the track 300 and the limiting member 400, so as to prevent the curtain body 100 from loosening. For example, the limiting member 400 includes a first limiting member 410 and a second limiting member 420, and the first section of the first limiting member 410 is clamped in the first track 310, and the first section of the second limiting member 420 is clamped in the second track 320, so as to prevent the curtain body 100 from loosening when subjected to external force.

[0047] The second section of the limiting member 400 is wound around the rolling tube 210 , and the second section of the limiting member 400 is in close contact with the curtain body 100 wound around the rolling tube 210 .

[0048] It can be understood that the windproof roller blind provided by the embodiment of the utility model is designed that the limit member 400 is designed to be sheet-shaped, and the first section of the limit member 400 is stuck in the track 300 and forms an angle with the curtain body 100, so that the curtain body 100 can be restricted in the track 300 to prevent movement in the left and right directions; and the second section of the limit member 400 is wound on the roller tube 210 and is in close contact with the curtain body 100 wound on the roller tube 210. This can avoid the phenomenon that when the curtain body 100 is wound on the roller tube 210, the limit member 400 causes the thickness of the two ends of the roller tube 210 to be large, the middle thickness of the curtain body 100 is thin, and the uneven thickness causes the curtain body 100 to wrinkle. This allows both sides of the curtain body 100 to remain flat, so as to prevent the curtain body 100 from wrinkling when it is rolled up and stacked, and can improve the overall flatness of the roller blind curtain body.

[0049] Combination Figure 4 and Figure 5Specifically, the position-limiting member 400 includes a clamping member 430 and a connecting member 440. The connecting member 440 and the clamping member 430 can be folded and connected. The connecting member 440 is arranged on the curtain body 100, and the connecting member 440 is connected to the curtain body 100. The first section of the clamping member 430 is clamped and slid in the track 300, and the second section of the clamping member 430 is in close contact with the curtain body 100 wound on the rolling tube 210. The folding connection method can make the position-limiting member 400 completely clamped in the track through the clamping member 430, which can effectively prevent the position-limiting member 400 from sliding out of the track 300, thereby preventing the curtain body 100 from moving in the left and right directions, further improving the overall flatness of the rolling curtain body 100, and preventing wrinkles when rolling up.

[0050] Combination Figure 3 Furthermore, in order to ensure that the limiting member 400 can be firmly attached to the curtain body 100 on the roller tube 210 when it is wound from the track 300 to the roller tube 210, thereby further preventing the curtain body 100 from wrinkling and ensuring the overall flatness of the rolling curtain body 100, in some embodiments of the utility model, a transition section 450 is provided between the first section of the clamping member 430 located in the track 300 and the second section of the clamping member 430 wound on the roller tube 210, and the transition section 450 is in a twisted state, which makes full use of the twisting force generated by the transition section 450 of the clamping member 430.

[0051] Of course, in some embodiments of the present invention, the rigidity of the clamping member 430 is greater than the rigidity of the connecting member 440. For example, the clamping member 430 can be in the form of a hard sheet, and the connecting member 440 can be in the form of a soft sheet. The clamping member 430 in the form of a hard sheet can increase the bearing capacity of the curtain body 100 in the left and right directions, and prevent the curtain body 100 from sliding in the left and right directions and causing wrinkles. The connecting member 440 in the form of a soft sheet can make it easier for the stopper 400 to engage with the curtain body 100, and can also ensure the smoothness of the joint between the stopper 400 and the curtain body, thereby improving the overall flatness of the rolling curtain body 100.

[0052] Furthermore, in order to prevent the edge of the curtain body 100 from wrinkling when the stopper 400 is wound on the roller tube 210, the ratio of the thickness of the clamping member 430 to the thickness of the curtain body 100 is set to be less than 3:1. For example, when the thickness of the clamping member 430 is 3 mm, the thickness of the curtain body 100 is 1 mm.

[0053] Combination Figure 6 and Figure 7 In some embodiments of the present invention, the stopper 400 includes a plastic part 460 and a soft cloth 470 . The soft cloth 470 wraps the plastic part 460 to form a clamping part 430 , and the soft cloth 470 extends out of the plastic part 460 to form a connecting part 440 .

[0054] Since the soft cloth 470 is soft, it can be welded to the curtain body 100 and maintain the same degree of expansion and contraction as the curtain body 100, which can further improve the overall flatness of the rolling curtain body 100 and prevent wrinkles. In addition, the soft cloth 470 can also increase the number of frictions at the contact point between the curtain body 100 and the track 300, thereby increasing the life of the rolling curtain.

[0055] The plastic part 460 , due to its hard material, can be stuck in the track 300 to prevent the curtain body 100 from escaping from the track 300 , further limiting the movement of the curtain body 100 in the left and right directions, thereby maintaining the overall flatness of the rolling curtain body 100 and preventing wrinkles.

[0056] In this embodiment, the plastic part 460 may be a hard PVC plastic part, and the soft cloth 470 may be a soft wear-resistant cloth.

[0057] Furthermore, in some embodiments of the present invention, the connecting member 440 located in the track 300 is arranged at an angle with the clamping member 430, and the connecting member 440 wound around the winding tube 210 is closely parallel to the clamping member 430. The angle is 50 to 90 degrees, for example, 50 or 90 degrees. The angle setting can prevent the connecting member 440 from being in contact with or parallel to the clamping member 430 when the track 300 slides, thereby preventing the connecting member 440 from sliding out of the track 300 in the left and right directions.

[0058] Of course, in some embodiments of the present invention, the angle may be a right angle (90 degrees), that is, the connecting member 440 and the clamping member 430 are connected in a "T" shape. For example, a T-shaped film auxiliary part (such as soft cloth 470) is used, and the softer part (such as the part of the soft cloth 470 extending outside the plastic part 460) is welded to the curtain body 100, so that the curtain body 100 and the soft cloth 470 are connected and fastened. When the curtain body 100 enters the track 300 (the track 300 can be a guide rubber strip), the hard film part (such as the plastic part 460) is stuck in the track 300 (such as the guide rubber strip). After the plastic part 460 escapes from the track 300 (such as the guide rubber strip), it can be flattened into a flat thin sheet under the action of the torsion of the track 300 and the winding tube 210, and evenly wound on the winding tube 210, thereby avoiding a large error in the winding diameter of the curtain body 100, which may cause the curtain body 100 to become wrinkled and deformed.

[0059] In addition, the “T”-shaped connection setting method can be to stick a PVC sheet on the soft wear-resistant curtain body, weld a PVC sheet, or wrap the PVC with a sewing thread. The method is not limited, and the main thing is to achieve the “T” shape formed by the curtain body 100 and the clip 430.

[0060] In some embodiments of the present invention, the windproof roller curtain also includes a lower beam 500, which is slidably connected to the track 300 and can slide in a first direction, that is, the lower beam 500 is connected to the bottom end of the curtain body 100. When the roller tube 210 rotates forward, the curtain body 100 moves upward and the curtain body 100 is wound. The lower beam 500 can straighten the curtain body 100 in the negative direction of the first direction; when the roller tube 210 rotates reversely, the curtain body 100 moves downward and the curtain body unfolds. The lower beam 500 can also straighten the curtain body 100 in the negative direction of the first direction, thereby maintaining the overall flatness of the curtain body 100 and preventing the curtain body 100 from wrinkling.

[0061] The lower beam 500 is arranged parallel to the roller tube 210, and the lower beam 500 is connected to the curtain body 100, which can limit the movement of the curtain body 100 in the third direction, that is, it can limit the movement of the curtain body 100 in the front and rear directions. For example, when the curtain body 100 is subjected to external force (such as wind force), the curtain body 100 can be prevented from flipping up.

[0062] In some embodiments of the present invention, the connecting member 440 and the curtain body 100 can be connected by welding or stitching, so that the connecting member 440 and the curtain body 100 can be tightly connected together to prevent the connecting member 440 from being easily detached.

[0063] In this specification, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
