[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clearly understood, the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 3-10 As shown, the utility model provides a windproof roller shutter, comprising an electric cloth-rolling tube 1, a bottom tube 2, a curtain 3 and two side rail assemblies 4, the electric cloth-rolling tube 1 and the bottom tube 2 are both arranged between the two side rail assemblies 4, the electric cloth-rolling tube 1 is arranged on the top of the two side rail assemblies 4, the upper part of the curtain 3 is rolled up on the electric cloth-rolling tube 1, and the bottom end is fixed on the bottom tube 2, zippers 5 are installed on both sides of the curtain 3, and a slide rail assembly 6 for moving the zipper 5 is provided inside the side rail assembly 4, a spring piece 8 is fixed on the slide rail assembly 6 by a screw 7, and the end of the spring piece 8 away from the slide rail assembly 6 abuts against the inner wall of the side rail assembly 4.

[0030] When the electric cloth-rolling tube 1 rotates, the electric cloth-rolling tube 1 starts to roll up or unroll the curtain 3, and the curtain 3 gradually moves upward or downward under the guidance of the slide rail assembly 6. During the movement, the elastic force of the spring piece 8 is used to straighten the slide rail assembly 6, so that the slide rail assemblies 6 on both sides simultaneously stretch the curtain 3, so that the curtain 3 is tightened. At the same time, the spring piece 8 is fixed to the slide rail assembly 6 by the screw 7, avoiding the use of the sponge 15, and eliminating the problem of aging of the sponge 15.

[0031] Furthermore, the slide rail assembly 6 includes an aluminum alloy groove tube 601 and a plastic track 602. The aluminum alloy groove tube 601 is arranged inside the side rail assembly 4, and the plastic track 602 is fixed inside the aluminum alloy groove tube 601. The zipper 5 slides in the plastic track 602, and the spring piece 8 is fixed to the aluminum alloy groove tube 601 by a screw 7.

[0032] The curtain 3 and the zipper 5 are welded together, and the zipper 5 slides in the plastic track 602, thereby realizing the lifting function of the curtain 3. The plastic track 602 is installed in the aluminum alloy groove tube 601, which strengthens the rigidity of the plastic track 602. The plastic track 602 is not easy to deform under the protection of the aluminum alloy groove tube 601, ensuring the smoothness of the sliding of the zipper 5.

[0033] Furthermore, the side rail assembly 4 and the aluminum alloy groove tube 601 are provided with an opening 9 for the curtain 3 to slide on one side thereof, the aluminum alloy groove tube 601 can move laterally in the side rail assembly 4, and a limit block 10 is provided on the inner wall of the side rail assembly 4 to limit the end of the spring sheet 8 from escaping.

[0034] The limiting block 10 and the inner wall of the side rail assembly 4 form a limiting groove, which is adjacent to the opening 9. The end of the spring piece 8 is confined in the limiting groove, ensuring that the spring piece 8 always works and will not escape from the limiting groove.

[0035] refer to Figure 8-10 A guide piece 11 for guiding the zipper 5 is fixed to the top of the aluminum alloy groove tube 601 by screws 16. Further, a guide hole 1101 for the zipper 5 to pass through is provided on the guide piece 11, and one side wall of the guide hole 1101 is an inclined side wall, and the aperture of the guide hole 1101 gradually decreases from top to bottom.

[0036] The bottom of the guide hole 1101 has the smallest aperture, which is no larger than the aperture in the plastic track 602 . The guide member 11 can guide the zipper 5 . Under the action of the guide member 11 , the zipper 5 can rise and fall directly without falling off the plastic track 602 .

[0037] Furthermore, a slot 12 for the curtain 3 to pass through is formed on a side of the plastic track 602 facing the curtain 3 , and the zipper 5 is confined within the plastic track 602 .

[0038] Furthermore, the side rail assembly 4 includes an outer sliding rail 401 and a rail cover 402, which are fixedly connected to form the side rail assembly 4. The side rail assembly 4 is provided with an opening 9 on one side facing the curtain 3 for the curtain 3 to slide, and a cavity 13 is formed inside the side rail assembly 4 to accommodate the aluminum alloy groove tube 601 and the spring piece 8.

[0039] refer to Figure 5There are multiple spring pieces 8, and both sides of the curtain 3 should be supported by spring pieces 8, that is, spring pieces 8 are fixed on the aluminum alloy groove tube 601 on both sides of the plastic track 602. Tooth grooves are opened on both sides of the aluminum alloy groove tube 601, and the screws 7 can be fixed at any position of the aluminum alloy groove tube 601, which is more reliable to use.

[0040] Furthermore, it also includes a mounting shell 14 , in which the electric cloth rolling tube 1 is mounted, and the mounting shell 14 is mounted on two side rail assemblies 4 .

[0041] The utility model utilizes screws 7 to fix spring pieces 8 instead of sponges 15 or sponges 15 plus spring pieces 8 to ensure that the curtain 3 is tightened, thereby ensuring the straightness of the curtain 3 and avoiding the derailment of the zipper 5, thereby ensuring the smoothness of the zipper 5; the spring piece 8 is fixed on the slide rail assembly 6 and the end thereof contacts the inner wall of the side rail assembly 4, thereby ensuring its elastic force.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
