[0035] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:

[0036] like Figures 1-6 As shown, a shutter telescopic rotation mechanism includes a guide rail beam 6, a pulley 8 and a plurality of shutters 15.

[0037] In this embodiment, a rotating rod 7 and a pulley 8 passing through the rotating rod 7 are installed inside the guide rail crossbeam 6, and at least three pulleys 8 are provided.

[0038] The pulley 8 is provided with a through hole for passing the rotating rod 7 . Each pulley 8 is provided with symmetrically arranged pulleys 83 , with at least two pulleys 83 on each side.

[0039] There are also raised rotating shafts 84 on both sides of the pulley 8. The rotating shaft 84 includes a worm wheel 81. The worm wheel 81 is connected to a worm 82 for transmission cooperation therewith. Both the worm wheel 81 and the worm 82 are installed inside the pulley 8.

[0040] Furthermore, the worm 82 is provided with a center hole connected to the fixed shaft 10 , and the other end of the fixed shaft 10 is connected to the louver 15 , and the louver 15 is provided with a port connected to the fixed shaft 10 .

[0041] The connection ports at both ends of the fixed shaft 10 are both non-circular connection ports. The first connection port 101 is a square interface with chamfers, and the second connection port 102 is a square interface.

[0042] Furthermore, the center hole of the worm 82 is configured as a square interface with chamfers, which is the same as the first connection port 101 , and the port of the louver 15 is configured as a square interface, which is the same as the second connection port 102 .

[0043] The fixed shaft 10 is provided with a through hole 103 at the center, and symmetrically arranged steps are provided on both sides of the through hole 103, and is also provided with a cotter pin 105 for inserting into the through hole 103. As one embodiment, the cotter pin 105 is configured as an R-shaped pin. In the shape of the cotter pin 3, the shape of the hypotenuse on the right side of the R shape can be further designed to be wavy.

[0044] After the louver 15 is connected to the pulley 8 placed inside the guide rail crossbeam 6 through the fixed shaft 10, the cotter pin 105 is inserted into the through hole 103 opened in the fixed shaft 10. The left vertical edge of the cotter pin 105 is inserted into the first through hole, and the wave-shaped part on the right side contacts the step 104 on one side.

[0045] In this embodiment, a slide rail 61 slidably engaged with the pulley 8 and a pull rope 9 connecting the pulley 8 are further provided inside the guide rail crossbeam 6 .

[0046] Among them, there are at least two pull ropes 9, and the pulleys 83 on one side of at least two pulleys 8 are connected to each other through the pull ropes 9 and reinforced by tightening screws. At least one pull rope 9 is connected to the extension part of the outer wall of the guide rail beam 6.

[0047] Furthermore, the pulley 8 that is not connected to the pull rope 9 has a pulley 83 on one side thereof connected to the belt pull seat 11 .

[0048] In this embodiment, the guide rail crossbeam 6 is equipped with a driving wheel 4, a driven wheel 13 and a fixed plate 12. A synchronous belt 14 is wound around the driving wheel 4 and the driven wheel 13, and a belt pull seat 11 is installed on the synchronous belt 14.

[0049] The driving wheel 4 is mounted on the left side of the guide rail beam 6 through the fixing plate 12 , and the driven wheel 13 is mounted on the right side of the guide rail beam 6 through the fixing plate 12 .

[0050] The portion of the rotating rod 7 between the two fixing plates 12 is also designed to be non-circular, and the portion of the rotating rod 7 outside the two fixing plates 12 is designed to be circular.

[0051] Furthermore, the driving wheel 4 is transmission-connected to the first motor 1 , and the rotating rod 7 is transmission-connected to the second motor 2 .

[0052] Specifically, the first motor 1 is provided with a transmission rod 3 , and the first motor 1 is coupled with the driving wheel 4 through the transmission rod 3 .

[0053] The synchronous belt 14 is connected to the first motor 1 through the transmission rod 3 .

[0054] The rotating rod 7 is provided with a coupling 5, and the rotating rod 7 is in transmission cooperation with the second motor 2 through the coupling 5, so as to realize the change of transmission direction.

[0055] In this embodiment, when the first motor 1 is in working state, the transmission rod 3 rotates and drives the synchronous belt 14 to move, and the synchronous belt 14 then synchronously drives the pulley 8 to move laterally. The pulley 8 can slide on the rotating rod 7. At the same time, each louver 15 moves laterally synchronously with the pulley 8.

[0056] When the second motor 2 is in operation, the rotating rod 7 rotates, which drives the worm gear to rotate, and the worm gear in turn drives the worm to rotate, thereby causing the fixed shaft 10 and the shutter 15 to flip.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
