Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 7 As shown, the unpowered roller shutter reel support includes a reel 1, a curtain body 2 is wound on the reel 1, multiple reels 1 are connected in series, and the ends of two adjacent reels 1 are connected by a universal coupling 3, thereby realizing a non-linear connection between multiple reels 1, meeting the installation requirements of fireproof roller shutters in complex scenes. During actual installation, the reel 1 at one end is also connected to a driving device, such as a motor, and the rotating shaft of the motor is connected to the end of the reel 1 through a connector, so that the motor drives multiple reels 1 to rotate synchronously.

[0029] like Figure 3 and Figure 4 As shown, a roller support body 4 is provided on the reel 1, and the number of roller support bodies 4 installed can be increased or decreased according to the length of the reel 1. The roller support body 4 includes two support plates 5 arranged opposite to each other in the left and right directions along the length direction of the reel 1, a horizontal plate is fixedly installed between the rear ends of the two support plates 5 by bolts, and a top plate 6 is also fixedly installed between the tops of the two support plates 5 by bolts; a mounting groove 7 is provided on the support plate 5 and is arranged transversely through the length direction of the reel 1, the reel 1 is located in the mounting groove 7, and a through opening 8 for the curtain body 2 to pass through is provided on the front side of the mounting groove 7, and two rollers 9 arranged in parallel in front and back are rotatably installed between the two support plates 5, and the two rollers 9 support the bottom of the reel 1 wound with the curtain body 2. The roller bracket body 4 can support the reel 1 and the curtain body 2 wound on the reel 1 at the same time, with a better load-bearing effect, and the installation position of the roller bracket body 4 is not limited to being installed only at the end of the reel 1. A plurality of roller bracket bodies 4 can be evenly arranged along the length direction of the reel 1, so that the gravity exerted on the reel 1 and the curtain body 2 can be more evenly distributed through the plurality of roller bracket bodies 4, thereby avoiding the reel 1 from being compressed, bending and deforming, and increasing the service life of the reel 1.

[0030] A top roller 10 is also rotatably installed between the two bracket plates 5. The top roller 10 and the roller 9 located on the front side are respectively located on the upper and lower sides of the through opening 8. The top roller 10 and the two rollers 9 are arranged parallel to the reel 1. The opening between the top roller 10 and the rollers 9 located therebelow is not large enough for another reel 1 to pass through, thereby preventing the reel 1 from escaping from the through opening 8 at the front end of the mounting groove 7.

[0031] In order to facilitate the installation of the supporting wheel bracket body 4, a mounting frame 11 is provided on the supporting wheel bracket body 4. Figure 4 and Figure 5 As shown, the mounting frame 11 includes a lower connecting seat 12, an upper connecting seat 13 and a connecting pipe 14. The lower connecting seat 12, the upper connecting seat 13 and the connecting pipe 14 are all in the shape of a hollow square tube. The bottom of the lower connecting seat 12 and the top of the upper connecting seat 13 are welded with fixing plates. The fixing plate at the bottom of the lower connecting seat 12 is fixedly installed on the top plate 6 by bolts. The lower end of the connecting pipe 14 is movably connected to the lower connecting seat 12, and the fixing plate on the top of the upper connecting seat 13 is fixedly installed on the top of the building by expansion bolts.

[0032] The upper end of the connecting pipe 14 is vertically slidably sleeved in the upper connecting seat 13. Figure 5 As shown, a positioning pin 15 is movably installed on the connecting tube 14, and a plurality of positioning holes 16 for the positioning pin 15 to be inserted into are provided on the upper connecting seat 13. The plurality of positioning holes 16 are evenly spaced vertically. By inserting the positioning pin 15 into different positioning holes 16, the height of the support wheel bracket body 4 and the reel 1 can be adjusted according to installation requirements.

[0033] like Figure 6 As shown, a through hole 17 is provided on the left side wall of the upper end of the connecting tube 14, and the positioning pin 15 is movably installed in the through hole 17. A stopper 18 is integrally formed at the right end of the positioning pin 15. The stopper 18 is cylindrical and coaxially arranged with the positioning pin 15. A first spring 19 for pushing the positioning pin 15 out of the through hole 17 is connected between the stopper 18 and the right side wall of the connecting tube 14. A positioning groove is provided at the right end of the stopper 18. The left end of the first spring 19 extends into the positioning groove, and the right end is welded to the right side wall of the connecting tube 14. The part of the positioning pin 15 extending out of the through hole 17 is hemispherical. When the first spring 19 pushes the positioning pin 15 to snap into the positioning hole 16, the resistance of the connecting tube 14 moving along the upper connecting seat 13 can be increased; when the connecting tube 14 is moved up and down by force, the positioning pin 15 can be disengaged from the positioning hole 16 at the current position and snapped into the adjacent upper or next positioning hole 16, thereby playing a preliminary locking role when the connecting tube 14 is adjusted up and down.

[0034] In order to prevent the supporting wheel bracket body 4 and the connecting tube 14 from being separated from the upper connecting seat 13 downward due to the action of gravity, a push rod 21 is slidably installed on the front side wall of the connecting tube 14, and an opening groove for avoiding the push rod is provided on the front side wall of the upper connecting seat 13. The sliding direction of the push rod 21 extends forward and backward perpendicular to the moving direction of the positioning pin 15. The push rod 21 is in the shape of a polygonal column, and a polygonal mounting hole matching the push rod 21 is provided on the front side wall of the connecting tube 14 to prevent the push rod 21 from rotating in the mounting hole; a plug plate 22 located in the connecting tube 14 is fixedly installed at the rear end of the push rod 21. The plug plate 22 is L-shaped. One arm perpendicular to the push rod 21 is fixedly mounted on one end of the push rod 21 by bolts, and one arm of the insert plate 22 parallel to the push rod 21 is provided with a rectangular hole 23 for the stopper 18 to pass through, and a slot 24 is provided on the outer side of the stopper 18 for the insert plate 22 located at the edge of the rectangular hole 23 to be inserted, and the slot 24 is arranged in a ring shape around the peripheral wall of the stopper 18; when the insert plate 22 is inserted into the slot 24, the stopper 18 and the positioning pin 15 are restricted from moving horizontally along the through hole 17, so that the positioning pin 15 cannot be separated from the positioning hole 16, and further the upper end of the connecting pipe 14 cannot move up and down along the upper connecting seat 13, and the upper end of the connecting pipe 14 is further locked.

[0035] The front end of the push rod 21 is integrally formed with a push block 26, and the push rod 21 between the front side wall of the connecting tube 14 is sleeved with a second spring 27; when there is no external force, the second spring 27 drives the push rod 21 and the plug plate 22 to move forward as a whole, so that the plug plate 22 located at the edge of the rectangular hole 23 is inserted forward into the slot 24, and the upper end of the connecting tube 14 is locked. After the upper connecting seat 13 is fixed to the top of the building, the plug plate 22 is disengaged from the slot 24 by pressing the push block 26 backward, and then the connecting tube 14 can be moved up and down by force, and the installation height of the supporting roller bracket body 4 and the reel 1 can be preliminarily adjusted.

[0036] like Figure 7 As shown, the lower end of the connecting tube 14 is vertically slidably sleeved in the lower connecting seat 12, and a vertically extending screw 28 is rotatably installed at the bottom of the lower connecting seat 12 through a bearing, and a connecting plate is welded in the lower end of the connecting tube 14, and the connecting plate is threadedly connected to the screw 28. After the installation height of the supporting roller support body 4 and the reel 1 is initially adjusted by moving the connecting tube 14 up and down along the upper connecting seat 13, the lower connecting seat 12 can be driven to move up and down slightly relative to the connecting tube 14 by rotating the screw 28, so as to adjust multiple supporting roller support bodies 4 located on the same reel 1 to the same height, so that the reel 1 remains horizontal.

[0037] The lower end of the screw rod 28 is also integrally formed with a coaxially arranged hexagonal column 29, and a through hole 30 is provided at the front side wall of the lower connecting seat 12 at a position corresponding to the position of the hexagonal column 29, so that the hexagonal column 29 and the screw rod 28 can be rotated by twisting the hexagonal column 29 with a wrench.

[0038] In addition, locking bolts are screwed into the right sides of the upper and lower ends of the connecting pipe 14, and strip holes for the corresponding locking bolts to pass through are respectively provided on the side walls of the upper connecting seat 13 and the lower connecting seat 12. After the upper connecting seat 13, the connecting pipe 14 and the lower connecting seat 12 are installed in place, the upper and lower locking bolts are tightened to make the connection between the upper connecting seat 13, the connecting pipe 14 and the lower connecting seat 12 more stable and reliable.
