[0036] Please refer to Figure 1 and Figure 2 According to the first aspect of the present invention, the rolling curtain protection structure includes a guide rail assembly and multiple rolling curtain assemblies 3, the guide rail assembly includes an installation rail 1, the installation rail 1 includes at least one bending section 13 and at least two straight sections 12, the two straight sections 12 are connected by the bending section 13, and the installation rail 1 is provided with an installation guide groove 11; multiple rolling curtain assemblies 3 are installed in the installation guide groove 11, and the multiple rolling curtain assemblies 3 are arranged in sequence along the installation rail 1, each rolling curtain assembly 3 includes a protective pad 31, a short partition 32 and a roller component, the short partition 32 is arranged at one end of the protective pad 31, the roller component is arranged on the short partition 32, the short partition 32 is inserted into the installation guide groove 11, the roller component rolls and abuts against the groove wall of the installation guide groove 11, the rolling curtain assembly 3 moves along the installation rail 1 through the roller component, and the multiple protective pads 31 are adjacent to each other for protection.

[0037] According to the roller shutter protection structure of the embodiment of the present invention, a plurality of roller shutter assemblies 3 are sequentially arranged on the mounting rail 1 to form protection, the roller shutter assemblies 3 are installed with the roller assembly through the short partition 32, and the protection pad 31 plays a protective role. The mounting rail 1 forms a straight section 12 and a bent section 13 to surround multiple surfaces of the protected equipment, that is, a plurality of roller shutter assemblies 3 can be arranged on the straight section 12 and the bent section 13 of the mounting rail 1, thereby forming multi-faceted protection, and at the same time, the roller shutter assemblies 3 can be rolled in the mounting guide groove 11 through the roller assembly to move along the mounting rail 1, and when the plurality of roller shutter assemblies 3 move to one end of the mounting rail 1, multiple surfaces of the protected equipment can be exposed, thereby increasing visibility and improving the operating space. It can be understood that multiple rolling shutter assemblies 3 can be moved and unfolded along the mounting rail 1 to achieve multi-faceted protection. In addition, multiple rolling shutter assemblies 3 can be moved and stored along the mounting rail 1. At this time, multiple faces of the protected equipment can be exposed. Compared with setting protective plates on multiple faces of the protected equipment, it is easy to operate and does not need to open the protective plates on multiple faces one by one. A wider field of view can be obtained to increase visibility. In one embodiment, the protective pad 31 is a transparent pad. When performing protection, the protected equipment can be directly observed from the outside, which increases visibility.

[0038] In this embodiment, the mounting rail 1 extends in the horizontal direction, and the rolling shutter assembly 3 extends in the vertical direction, so that multiple rolling shutter assemblies 3 are arranged in sequence in the horizontal direction on the mounting rail 1, thereby forming multi-sided protection. For example, the mounting rail 1 specifically has two straight sections 12 and one bent section 13, and the extension directions of the straight sections 12 at both ends are perpendicular to each other and connected by the bent section 13. In this way, the rolling shutter assemblies 3 arranged at the two straight sections 12 are on two sides of the protected equipment for protection. The bent section 13 is an arc-shaped structure, which plays a transition role, so that the rolling shutter assembly 3 can transition from one straight section 12 of the mounting rail 1 to another straight section 12, which is convenient for storage and protection. Of course, in other embodiments, the mounting rail 1 can also be provided with two bent sections 13 or multiple bent sections 13 to connect multiple straight sections 12 to form three-sided or more protection, thereby achieving a multi-sided protection effect.

[0039] like Figure 8 and Fig. 9 As shown, illustratively, the number of single-piece rolling curtain assemblies 3 is determined according to the size of the required protection surface, and each single-piece rolling curtain assembly 3 is connected to the mounting rail 1 through a roller component. Optionally, the protective pad 31 can be rotatably arranged to facilitate passing through the bending section 13. For example, one end of the protective pad 31 is inserted into the notch 321 of the short partition 32. In the width direction of the protective pad 31, that is, the extension direction of the mounting rail 1, the notch 321 is wide at both ends and narrow in the middle, so that the protective pad 31 can adaptively rotate in the notch 321. Of course, in other embodiments, the protective pad 31 can also be arranged to be bend and deform, and when the rolling curtain assembly 3 passes through the bending section 13, the protective pad 31 can be adaptively bent or adaptively rotated.

[0040] Optionally, the mounting guide rail 1 can be at the upper end of the rolling shutter assembly 3 to form an upper guide rail, or the mounting guide rail 1 can be at the lower end of the rolling shutter assembly 3 to form a lower guide rail. In other embodiments, two mounting guide rails 1 can be set at the upper and lower ends of the rolling shutter assembly 3, respectively, to improve the installation stability, which is not limited here.

[0041] like Figure 1 As shown, according to one embodiment of the present invention, the rolling shutter protection structure includes a support assembly 4 and two guide rail assemblies, the two guide rail assemblies are symmetrically arranged in the upper and lower directions, and the two guide rail assemblies are divided into an upper guide rail assembly and a lower guide rail assembly. One end of the rolling shutter assembly 3 is connected to the upper guide rail assembly, and the other end is connected to the lower guide rail assembly. One end of the support assembly 4 is connected to the upper guide rail assembly, and the other end is connected to the lower guide rail assembly.

[0042] It can be understood that the upper rail assembly and the lower rail assembly respectively limit the upper and lower ends of the rolling shutter assembly 3 to improve the installation and movement stability of the rolling shutter assembly 3. The support assembly 4 includes two support columns, which are respectively arranged at the two ends of the lower rail assembly to support the installation of the upper rail assembly. Exemplarily, the upper and lower ends of the protective pad 31 in the rolling shutter assembly 3 can be provided with short partitions 32 and roller components to keep the two ends of the protective pad 31 even. In addition, the protective pad 31 is moved along the installation rail 1 by the rolling component to reduce friction and thus reduce the wear of the two.

[0043] Please refer to Figure 3 , Figure 6 and Figure 7 According to one embodiment of the present invention, a first vertical groove 111 is provided on the bottom wall of the mounting guide groove 11, a first transverse groove 112 is provided on the side wall of the mounting guide groove 11, and the roller component includes a first roller 331 and a second roller 332. The first roller 331 is provided on the end surface of the short partition 32 away from the protective pad 31, and the second roller 332 is provided on the side wall of the short partition 32. The first roller 331 rolls in the first vertical groove 111, and the second roller 332 rolls in the first transverse groove 112. It can be understood that the first roller 331 and the second roller 332 cooperate to position the rolling shutter assembly 3 to move along the mounting guide rail 1 to improve the movement stability and prevent shaking. It should be noted that the first roller 331 and the second roller 332 can be placed flat or vertically, which is not limited here.

[0044] According to an embodiment of the present invention, the axis of the first roller 331 is perpendicular to the axis of the second roller 332. In this embodiment, the first roller 331 is placed horizontally, that is, the outer peripheral surface of the first roller 331 can roll against the left wall or the right wall of the first vertical groove 111, so that the horizontal degree of freedom of the first roller 331 is limited by the left and right side walls of the first vertical groove 111. At the same time, the second roller 332 is placed vertically, and since the first transverse groove 112 is grooved in the transverse direction, the second roller 332 can roll against the lower side wall of the first transverse groove 112, and at this time, the upper side wall of the first transverse groove 112 can stop the second roller 332 from moving upward. In this way, the upper and lower side walls of the first transverse groove 112 limit the vertical degree of freedom of the second roller 332, so that the roller component can move smoothly along the mounting guide rail 1.

[0045] According to one embodiment of the present invention, the roller shutter assembly 3 includes a plurality of short partitions 32, and the plurality of short partitions 32 are arranged in sequence along the width direction of the protective pad 31, and two adjacent short partitions 32 are rotatably connected via a rotating shaft. It should be noted that the width direction of the protective pad 31 is the extension direction of the mounting guide rail 1, and a roller component can be installed on each short partition 32, and the plurality of short partitions 32 can rotate relative to each other in pairs, so as to facilitate passing through the bending section 13. Exemplarily, the roller component can be installed on the rotating shaft for easy installation. It can be understood that the single-piece roller shutter assembly 3 can be widened by increasing the number of short partitions 32.

[0046] Please refer to Figure 6 , Figure 7 , Fig.10 and Fig.11 According to one embodiment of the present invention, the rolling shutter assembly 3 includes a long partition 34, which is arranged between two adjacent protective pads 31. Long grooves 341 are opened on both sides of the long partition 34, and the protective pads 31 located on both sides of the long partition 34 are partially inserted into the long grooves 341.

[0047] It can be understood that the long partition 34 is used to separate two adjacent protective pads 31, which is convenient for the stable installation of the two, that is, the multiple protective pads 31 are interconnected through the long partition 34, which is conducive to improving the protection effect compared with the single protective pad 31 protecting alone. In one embodiment, one side of the protective pad 31 is placed in the long groove 341 on one side of the long partition 34, and then an end plate 36 is added to the end of the mounting guide rail 1. The end plate 36 is fixedly connected to the single roller assembly 3 through the upper and lower roller assemblies, and the other side of the protective pad 31 is placed in the limit groove on the end plate 36.

[0048] In one embodiment, the rolling shutter assembly 3 includes a pressure plate 35, and pressure grooves 342 are respectively opened at both ends of the long partition 34, and the pressure grooves 342 are connected to the long groove 341. After the protective pad 31 is inserted into the long groove 341, the pressure plate 35 is pressed into the pressure groove 342 to fix the protective pad 31 by pressing, thereby connecting the protective pad 31 and the long partition 34, improving the connection stability and facilitating assembly and disassembly.

[0049] Please refer to Figure 1 , Figure 4 and Figure 5 According to one embodiment of the present invention, the guide rail assembly includes a storage guide rail 2, which is connected to one end of the protection guide rail. The storage guide rail 2 is provided with a storage ring groove 21, which is connected to the installation guide groove 11. A plurality of roller blind assemblies 3 can be moved along the installation guide groove 11 to the storage ring groove 21 for storage. It can be understood that when the equipment needs maintenance, the entire roller blind assembly 3 is pushed into the storage ring groove 21 of the storage guide rail 2. When the equipment is working, the entire roller blind assembly 3 is pulled open along the installation guide rail 1 for protection, and storage is convenient.

[0050] According to one embodiment of the present invention, the bottom wall of the storage ring groove 21 is provided with a second vertical groove 211, and the second vertical groove 211 is correspondingly connected to the first vertical groove 111, and the side wall of the storage ring groove 21 is provided with a second transverse groove 212, and the second transverse groove 212 is correspondingly connected to the first transverse groove 112. It can be understood that the first roller 331 can move along the first vertical groove 111 to the second vertical groove 211, and the second roller 332 can move along the first transverse groove 112 to the second transverse groove 212, so that the rolling shutter assembly 3 is moved and stored at the storage guide rail 2.
