[0059] For existing rolling shutters, due to the structural limitations of the box body and the rolling door machine, the overall size is too large (the height of the existing fireproof rolling shutter box is about 500 mm - 800 mm), occupying too much ceiling space and affecting the overall decorative elevation.

[0060] The present utility model provides a rolling shutter device, which solves the problem that the box body of the rolling shutter device occupies too much ceiling space.

[0061] To solve the above problems, the general idea of the technical solution of the present utility model is as follows: By increasing the horizontal (level) length dimension of the fire shutter box body, on the basis of the original box body reel for storing the shutter, the box body is also used as a shutter storage space to reduce the vertical height of relying only on the reel to store the shutter, so as to achieve the purpose of reducing the excessive elevation occupied by the box.

[0062] Figure 1 As shown in the structural schematic diagram of a shutter device provided by an embodiment of the present utility model, the shutter device 1 includes: a box 10, a curtain surface 11 and a rotating reel 12, wherein the rotating reel 12 is connected to the curtain surface 11 and is installed on the first side 10a inside the box 10.

[0063] The box 10 includes a receiving space 100, an opening 101 and at least one first guide rail 102. Among them, the receiving space 100 is used to receive the rolled-up curtain surface 11, and the length of the receiving space 100 in the first horizontal direction F1 is much greater than the height in the vertical direction F2; the opening 101 is provided on the second side 10b of the box 10, and the first side 10a is opposite to the second side 10b; the first guide rail 102 is installed on the third side 10c and / or the fourth side 10d inside the receiving space 100 and inside the box 10. The third side 10c is adjacent to the second side 10b and is opposite to the fourth side 10d. Preferably, there are two first guide rails 102, which are respectively provided on the third side 10c and the fourth side 10d inside the box 10.

[0064] As Figure 2 shown, when the curtain surface 11 is rolled up, the rotating reel 12 drives the curtain surface 11 to enter the box 10 from the opening 101 and makes the curtain surface 11 completely received in the receiving space 100 along the first guide rail 102.

[0065] Specifically, Figure 1 is the state when the curtain surface 11 is lowered, Figure 2 is the state when the curtain surface 11 is rolled up. During the process of rolling up the curtain surface 11, the top end of the curtain surface 11 enters the receiving space 100 of the box 10 from the opening 101 along the first guide rail 102. This process depends on the drive of the rotating reel 12. A chain, rope, steel wire, etc. can be used to connect the rotating reel 12 and the curtain surface 11.

[0066] The shutter device 1 further includes a door operator 13. As Figure 3 shown in the comparison diagram of the installation position of the door operator 13, the door operator 13 is detachably installed on the upper part of the box 10 (such as Figure 1 ), the outer side (such as Figure 2 area A) or the lower part (not shown in the figure), etc., and is drivingly connected to the rotating reel 12.

[0067] Specifically, the rolling door machine 13 includes a rolling belt 130, a driving wheel 131 and a driven wheel 132. When in use, the rolling door machine 13 drives the driven wheel 132 to rotate through the driving wheel 131, and drives the rotating scroll gear 123 of the rotating scroll 12 to rotate through the rolling belt 130. In addition, the rolling door machine 13 can be electrically connected to a control device (not shown in the figure), and the opening and closing of the rolling door machine 13 are controlled through the control device. The rotating scroll 12 is detachably installed on the box 10 through a fixing member 16.

[0068] As Figure 4 shown, the rolling curtain device 1 further includes a manual chain 14, which is drivingly connected to the rotating scroll 12 and is used to manually roll up the curtain surface 11 when the rolling door machine 13 fails. Specifically, the manual chain 14 can be connected to the driving wheel 131, and the driving wheel 131 is driven to rotate manually.

[0069] A plurality of cross beams 103 can be arranged in the box 10 to increase the stability of the box 10. When the curtain surface 11 is rolled up, it bypasses the rotating scroll 12 from the cross beam 103 along the first guide rail 102.

[0070] As Figure 5 shown, a plurality of keel anchor points 104 are reserved at the bottom of the box 10 to realize the direct installation of the rolling curtain device 1 with the keel 2 of the suspended ceiling or other decorative structures, and further reduce the decorative elevation.

[0071] The rolling curtain device 1 further includes a frame 15, which is connected to the box 10 and is used to support the curtain surface 11 when it is lowered. Specifically, at least one second guide rail 150 is arranged on the frame 15. When the curtain surface 11 is lowered, it reaches the bottom of the ground along the second guide rail 150, and the second guide rail 150 is communicated with the first guide rail 102. The first guide rail 102 and the second guide rail 150 can be two respectively, and the two first guide rails 102 or the two second guide rails 150 are arranged oppositely.

[0072] In some other embodiments, the other structures of the rolling curtain device 1 are the same as those in the above embodiments. The only difference is that the number of rotating scrolls 12 is different. As Figure 6 shown, the rotating scroll 12 can be two, including a first rotating scroll 120 and a second rotating scroll 121, and the two rotating scrolls are linked. The second rotating scroll 121 drives the first rotating scroll 120 to rotate. At this time, the rolling door machine 13 and / or the manual chain 14 are drivingly connected to the second rotating scroll 121 (not shown in the figure) to drive the second rotating scroll 121 to rotate.

[0073] In this embodiment, the number of the first guide rails 102 can be correspondingly increased, for example, it can be four, which are arranged corresponding to the position when the curtain surface 11 is retracted. Specifically, two are arranged at opposite positions along the line between the opening 101 and the first rotating scroll 120 (i.e., the third side 10C and the fourth side 10d), and two are arranged at opposite positions along the line between the first rotating scroll 120 and the second rotating scroll 121 (i.e., the third side 10C and the fourth side 10d) ( Figure 6 not shown).

[0074] In some other embodiments, as Figure 7 shown, there can be three rotating scrolls 12, including a first rotating scroll 120’, a second rotating scroll 121’ and a third rotating scroll 122. The rolling door machine 13 and / or the manual chain 14 are drivingly connected to the third rotating scroll 122 (not shown in the figure) to drive the third rotating scroll 122 to rotate, and the third rotating scroll 122 drives the second rotating scroll 121’ and the first rotating scroll 120’ to rotate in sequence. The above are only examples of the present utility model, and the number of the rotating scrolls 12 is not limited and can be adjusted according to the actual application scenario.

[0075] In this embodiment, the number of the first guide rails 102 can also be correspondingly increased, for example, it can be six, which are arranged corresponding to the position when the curtain surface 11 is retracted, in pairs and opposite to each other. The specific principle is the same as that in the above Figure 6 setting, and will not be elaborated here.

[0076] To sum up, the present utility model relies on increasing the size of the longitudinal long fireproof rolling curtain box body. On the basis of the original scroll for storing the rolling curtain, the box body is also used as the rolling curtain storage space to reduce the vertical height of relying only on the scroll to store the rolling curtain, so as to achieve the purpose of reducing the excessive elevation occupied by the box.

[0077] Moreover, the present utility model optimizes the position layout of the original rolling door machine to achieve modular installation. The cloth rolling machine can be arranged independently outside the overall fireproof rolling curtain box. Flexible installation and arrangement can be realized at the upper and lower ends of the box, and the space can be flexibly utilized, so as to further compress the overall size of the box and reduce the vertical height of the box itself. The height can be reduced by more than 45% - 70%, and the elevation occupied by the space can be reduced. The whole design is processed in the factory and directly assembled on-site in modules. In addition, keel anchor points are reserved at the bottom of the box, which can be connected to the ceiling structure, optimize the construction operation process, reduce the construction difficulty and shorten the construction and installation period.

[0078] The embodiments of the present utility model have been described above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present utility model, those of ordinary skill in the art can also make many forms without departing from the purpose of the present utility model and the scope protected by the claims, and all of them fall within the protection scope of the present utility model.
