[0034] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and embodiments.

[0035] Please refer to Figures 1 to 10 , the windproof roller 10 provided by the embodiments of the present application will be described. The windproof roller 10 comprises a window frame 11 and a roller body 13.

[0036] The first winding drum 12 is mounted on the top of the window frame 11, and the first winding drum 12 can rotate to wind or unwind the roller body 13 between the two window frames 11. The roller body 13 is provided with at least a first flexible metal sheet 131 on the left and right sides, and when the roller body 13 is wound on the first winding drum 12, the roller body 13 is arranged in parallel with the first flexible metal sheet 131, and when the roller body 13 is unwound between the two window frames 11, the roller body 13 is perpendicular to the first flexible metal sheet 131.

[0037] Specifically, by arranging the first flexible metal sheet 131 on the left and right sides of the roller shutter body 13, when the roller shutter body 13 is unfolded between the two window frames 11, the roller shutter body 13 is perpendicular to the first flexible metal sheet 131, and the first flexible metal sheet 131 can provide support for the roller shutter body 13 to prevent the roller shutter body 13 from being blown up after being unfolded under the action of strong wind; on the one hand, it can solve the problem of noise caused by the wind blowing on the roller shutter body 13, prevent noise, and improve the user's experience; on the other hand, the first flexible metal sheet 131 can provide effective support for the edge of the roller shutter body 13 to prevent the roller shutter body 13 from tearing, which can further improve the service life of the roller shutter body 13.

[0038] In addition, by arranging the first flexible metal sheet 131, when the roller shutter body 13 is wound on the first winding drum 12, the support force can be provided to avoid the soft roller shutter body 13 from being deviated during winding on the first winding drum 12, thereby avoiding the problem of the roller shutter body 13 being stacked on one side, and effectively improving the reliability of the roller shutter body 13 during winding.

[0039] In some embodiments of the present application, the opposite side of the two window frames 11 is provided with a first guide groove 111, and the first flexible metal sheet 131 can be inserted into the first guide groove 111 when the roller shutter body 13 is unfolded between the two window frames 11. Specifically, when the roller shutter body 13 is wound, the first flexible metal sheet 131 on both sides is arranged in parallel with the roller shutter body 13 and is wound together in the first winding drum 12; when the roller shutter body 13 is unfolded between the two window frames 11, the roller shutter body 13 is arranged perpendicular to the first flexible metal sheet 131, and the first flexible metal sheet 131 can be inserted into the first guide groove 111; such structure not only can provide support for the unfolded roller shutter body 13 by arranging the first flexible metal sheet 131; but also can insert the first flexible metal sheet 131 into the first guide groove 111 to further improve the problem of the roller shutter body 13 being blown up under strong wind.

[0040] More specifically, the first guide groove 111 penetrates through the top of the two window frames 11, and the first winding drum 12 is rotatably installed on the top of the two window frames 11 and is arranged in an up-down interval with the top of the first guide groove 111. By arranging the first winding drum 12 and the first guide groove 111 in an up-down interval, the first flexible metal sheet 131 has a certain deformation area during the switching from parallel arrangement to perpendicular arrangement of the first flexible metal sheet 131 and the roller shutter body 13, so that the first flexible metal sheet 131 can be used normally without being stuck.

[0041] Preferably, the distance between the first winding drum 12 and the top of the first guide slot 111 is equal to or greater than the diameter of the first winding drum 12. The first flexible metal sheet 131 can be a steel sheet, an aluminum alloy sheet, a manganese steel sheet, or the like.

[0042] In some embodiments of the present application, one end of the roller shutter body 13 is fixedly connected to the first winding drum 12, and the other end of the roller shutter body 13 is provided with a first support rod 132, and the two ends of the first support rod 132 are movably installed on the two window frames 11. Since the left and right sides of the roller shutter body 13 are both provided with the first flexible metal sheet 131 for support, when the user needs to manually deploy or roll up the roller shutter body 13, the user can directly push the first support rod 132 up and down to complete the deployment or rolling up of the roller shutter body 13.

[0043] Specifically, the opposite side of the two window frames 11 is provided with a second guide slot 112, and the end of the first support rod 132 is movably installed corresponding to the second guide slot 112 on one side. The first guide slot 111 is recessed on the bottom surface of the second guide slot 112.

[0044] It should be noted that since the first guide slot 111 and the second guide slot 112 are recessed on the opposite side of the window width, taking the left window frame 11 as an example, the second guide slot 112 is located on the right side of the window frame 11 and is recessed from the right side of the window frame 11 to the left. At this time, the bottom surface of the second guide slot 112 is actually the side surface in the left-right direction, and the first guide slot 111 is recessed from the center position of the bottom surface of each second guide slot 112.

[0045] More specifically, the two window frames 11 are provided with elastic support members 113 in the second guide slots 112. The elastic support members 113 can prevent the two window frames 11 from being pressed during installation or under external force, causing the second guide slots 112 and the first guide slots 111 to deform, thereby improving the reliability of use.

[0046] In some embodiments of the present application, a roller shutter box 14 is further included, which is fixedly installed on the top of the two window frames 11, and the first winding drum 12 is detachably installed in the roller shutter box 14. By providing the roller shutter box 14, most of the parts can be stored, and the overall aesthetics of the windproof roller shutter 10 can be improved.

[0047] Specifically, the inside left and right sides of the roller shutter box 14 are provided with first buckling sites 141, and the two ends of the first winding drum 12 are provided with first buckling seats 121, which are buckled and installed in the first buckling sites 141.

[0048] Preferably, the first buckling site 141 is provided with first assembly protrusions 142 arranged in an up-down manner, and first buckling notches 143 are arranged at the front ends of opposite sides of the two first assembly protrusions 142 arranged in an up-down manner; the front ends of the upper and lower sides of the first buckling seat 121 are provided with first buckling elastic arms 123; after the first buckling seat 121 is inserted between the two first assembly protrusions 142, the first buckling elastic arms 123 can be buckled into the first buckling notches 143 to buckle and fix the first buckling seat 121.

[0049] More specifically, the first winding drum 12 is a hollow cylindrical structure and a first opening 1201 is formed through the left and right sides of the first winding drum 12, and the first plug 122 is rotatably installed on the first buckling seat 121, and the first plug 122 can be inserted into the first opening 1201.

[0050] In other embodiments of the present application, the first plug 122 of any one is provided with an extension rod 124, and the other end of the extension rod 124 away from the first plug 122 is provided with a supporting wheel 125 which can abut against the inner surface of the first winding drum 12; in this way, when the first winding drum 12 with a relatively small thickness is arranged, the supporting wheel 125 can be used to provide a supporting force for the first winding drum 12 to prevent the first winding drum 12 from being deformed.

[0051] It should be noted that the windproof roller shutter 10 can be manually rolled up or manually unfolded, and when it is manually rolled up or manually unfolded, only the up-down movement of the first supporting rod 132 is needed to realize the rolling up or unfolding of the entire roller shutter body 13. It can also be electrically rolled up or electrically unfolded; any first plug 122 can be connected to a motor, and the first plug 122 is driven to rotate by the motor to realize automatic rolling up or unfolding of the roller shutter body 13.

[0052] In other embodiments of the present application, the roller shutter body 13 is a flexible woven body which is woven by PVC, nylon, PET fiber, metal wire or cotton fiber. The left and right sides of the roller shutter body 13 are welded with first hot melt adhesive fabric sections 133 by a hot pressing process, and the first hot melt adhesive fabric sections 133 cover the first flexible metal sheet 131. Through the arrangement of the first hot melt adhesive fabric sections 133, the first flexible metal sheet 131 can be reliably connected; at the same time, when the subsequent roller shutter body 13 is rolled up or unfolded, it is convenient to switch between the parallel stacked state and the vertical arrangement state between the roller shutter body 13 and the first flexible metal sheet 131.

[0053] Specifically, the top of the roller shutter body 13 is provided with a second flexible metal sheet 136, the circumferential side of the first roller 12 is provided with at least one first assembly groove 126 extending along the axial direction of the first roller 12, and the second flexible metal sheet 136 is inserted into the first assembly groove 126. The axial direction of the first roller 12 is greater than or equal to the width of the left-right direction of the roller shutter body 13, and the end of the first roller 12 extends above the first guide groove 111, so that after the roller shutter body 13 is wound, the first hot melt adhesive fabric section 133 arranged on both sides of the roller shutter body 13 does not wrinkle, and the roller shutter body 13 is wound in the first roller 12 in parallel with the first flexible metal sheet 131, so that the flatness is higher and does not protrude.

[0054] The connection mode between the second flexible metal sheet 136 and the roller shutter body 13 is the same as that between the first flexible metal sheet 131 and the roller shutter body 13, which will not be described here.

[0055] Further, the bottom of the roller shutter body 13 is hot-pressed and welded with a second hot melt adhesive fabric section 134, the second hot melt adhesive fabric section 134 is covered with a glue strip 135; the second guide groove 112 is movably installed with the first support rod 132, and the first support rod 132 is provided with a second assembly groove 1321, and the glue strip 135 is arranged in the second assembly groove 1321.

[0056] It should be noted that the arrangement mode of the second hot melt adhesive fabric section 134 is substantially the same as that of the first hot melt adhesive fabric section 133, and the difference lies in that the first hot melt adhesive fabric section 133 is used to cover the first flexible metal sheet 131 or the second flexible metal sheet 136, and the second hot melt adhesive fabric section 134 is used to cover the glue strip 135. The glue strip 135 includes a hard glue strip 135 or a soft glue strip 135, which is arranged according to actual production needs.

[0057] The above is only a preferred embodiment of the present application, and only the technical principle of the present application is described in detail, and these descriptions are only for explaining the principle of the present application, and cannot be explained as a limitation on the protection scope of the present application in any way. Based on the explanation here, any modification, equivalent replacement and improvement made within the spirit and principle of the present application, and other specific embodiments of the present application that can be conceived by those skilled in the art without creative labor, should be included in the protection scope of the present application.
