It is light and beautiful, and is integrated with the overall aesthetic effect of the hospital ship, thereby improving the overall aesthetics. Example 2

[0026] Please refer to Figures 8-10. The outer surfaces of several rotating shafts 2 are all fixedly sleeved with connecting gears 14. The outer surface of the rear side of the left end of the outer frame 1 is rotatably penetrated by an adjusting shaft 15. The outer surface of the adjusting shaft 15 located outside the outer frame 1 is fixedly connected with a rotating disk 16. The outer surface of the adjusting shaft 15 away from the rotating disk 16 is fixedly sleeved with a driving bevel gear 18. The outer surface of the left end of the middle rotating shaft 2 is fixedly sleeved with a driven bevel gear 19. The driving bevel gear 18 is movably meshed with the outer surface of the driven bevel gear 19. In this embodiment, rotating the rotating disk 16 drives the adjusting shaft 15 to rotate the driving bevel gear 18, and the driving bevel gear 18 is meshed with the driven bevel gear 19, driving the rotating shaft 2 to rotate, and the rotating shaft 2 drives the connecting gear 14 thereon to rotate.

[0027] The left inner surface of the outer frame 1 is rotatably connected to a plurality of support shafts, and the outer surfaces of the plurality of support shafts are fixedly sleeved with transmission gears 17, and the plurality of transmission gears 17 are respectively movably meshed with the outer surfaces of the upper and lower adjacent connection gears 14. In this embodiment, when the middle rotating shaft 2 rotates, the connection gears 14 thereon are driven to rotate the rod, and under the cooperation of the transmission gears 17, the plurality of connection gears 14 cause the rotating shaft 2 to change at the same angle.

[0028] The outer surface of the rear side of the left end of the outer frame 1 is fixedly connected to a magnet 28 at the periphery of the adjustment shaft 15, and the outer surface of the turntable 16 is fixedly connected to a U-shaped rod 29, which is an iron rod and is adsorbed on the outer surface of the magnet 28. In this embodiment, the magnet 28 adsorbs the U-shaped rod 29 to limit the turntable 16, and cooperates with the meshing force between each gear and the meshing force between the active bevel gear 18 and the driven bevel gear 19 to prevent the shutter blade 3 from rotating autonomously.

[0029] The outer surface of the rectangular rod 21 is fixedly sleeved with a sleeve disc 27, and the diameter of the sleeve disc 27 is larger than the diameter of the rectangular rod 21. In this embodiment, the diameter of the sleeve disc 27 is larger than the diameter of the rectangular rod 21. When the rectangular rod 21 needs to be pulled, the sleeve disc 27 provides a force point for the adjuster, which facilitates pulling the rectangular rod 21.

[0030] The U-shaped rod 29 is then pulled to disengage one end of the U-shaped rod 29 from the magnet 28, and the U-shaped rod 29 is removed to release the limit on the turntable 16. The turntable 16 is driven to drive the adjusting shaft 15 to rotate the active bevel gear 18, and the active bevel gear 18 is meshed with the driven bevel gear 19 to drive the rotating shaft 2 to rotate. The rotating shaft 2 drives the connecting gear 14 thereon to rotate, so that the transmission gear 17 rotates. Under the transmission of the transmission gear 17, multiple connecting gears 14 are rotated at the same time, thereby driving multiple rotating shafts 2 to rotate at the same time, adjusting the inclination angle between each louver 3, thereby adjusting the opening and closing degree of the louver 3. After the adjustment is completed, the U-shaped rod 29 is inserted, so that the magnet 28 adsorbs the U-shaped rod 29, and the turntable 16 is limited. Example 3

[0031] Please refer to Figures 10-11, a rectangular groove 20 is provided on the left outer surface of the middle rotating shaft 2, a rectangular rod 21 adapted to the rectangular groove 20 is movably inserted on the right outer surface of the middle rotating shaft 2, a first spring 22 is fixedly connected to the right inner surface of the middle rotating shaft 2, and one end of the first spring 22 is fixedly connected to the rectangular rod 21. In this embodiment, the left and right adjacent rotating shafts 2 are spliced ​​by inserting the rectangular rod 21 into the rectangular groove 20.

[0032] A limiting rod 24 is movably inserted on the outer surface of the intermediate rotating shaft 2, and a pull plate 25 is fixedly connected to the outer surface of the limiting rod 24 located outside the rotating shaft 2. A second spring 23 is fixedly connected to the outer surface of the intermediate rotating shaft 2, and the other end of the second spring 23 is fixedly connected to the outer surface of the pull plate 25. A plurality of limiting holes 26 arranged in a linear array are provided on the outer surface of the rectangular rod 21. In this embodiment, the pull plate 25 is pulled outward to stretch the second spring 23, and the limiting rod 24 is disengaged from the inside of the limiting hole 26, and the rectangular rod 21 is released from the limit, thereby adjusting the position of the rectangular rod 21. After the adjustment is completed, the pull plate 25 is released, and the second spring 23 is reset, so that the limiting rod 24 is inserted into the corresponding limiting hole 26, and the rotating shaft 2 and the rectangular rod 21 are limited.

[0033] An adjustment notch 30 is provided on the right outer surface of the outer frame 1, and a connection notch 31 is provided on the left outer surface of the outer frame 1. The adjustment notch 30 provides a channel for adjusting the position of the rectangular rod 21, and the connection notch 31 allows one side of the rectangular rod 21 to extend from the connection notch 31 and connect the two shafts 2.

[0034] It should be further explained that, when multiple outer frames 1 are spliced ​​together, the connection notch 31 of the outer frame 1 at the leftmost end can be eliminated, and the adjustment notch 30 at the rightmost end can be eliminated to increase the aesthetics.

[0035] In the specific implementation process, when adjusting the opening and closing degree of the louver 3, the opening and closing degree of multiple adjacent louver slats 3 can be adjusted at the same time. At this time, the U-shaped rod 29 is removed, and the pull plate 25 is pulled outward to stretch the second spring 23, and the limit rod 24 is disengaged from the inside of the limit hole 26, and the sleeve plate 27 is pulled to extend one end of the rectangular rod 21 and deform the first spring 22. One end of the rectangular rod 21 is inserted into the rectangular groove 20. At this time, the pull plate 25 is released, and the second spring 23 is reset, so that the limit rod 24 is inserted into the corresponding limit hole 26, and the rotating shaft 2 and the rectangular rod 21 are limited, thereby connecting the rotating shaft 2 at the middle end of the two adjacent louvers. Therefore, when adjusting the opening and closing degree of the louver slats 3 in one louver, the opening and closing degree of the louver slats 3 in the two adjacent louvers can also be adjusted, thereby increasing the convenience of using the louver.

[0036] Working principle: In actual use of the present invention, the number of shutters to be installed is selected according to the length of the medical ship. When installing the shutters, the top support ear plate 6 and the bottom support ear plate 11 are respectively welded to the top and bottom of the outer frame 1, and the top support foot 7 and the bottom support foot 10 are welded to the opposite outer surfaces of the two adjacent decks 5, and then the top bolt 8 is screwed into the top through hole, and the top support ear plate 6 and the top support foot 7 are connected and fixed by the top nut 9, and then the top bolt 8 is screwed into the bottom through hole, and the bottom support ear plate 11 and the bottom support foot 10 are fixed by the bottom nut 13, thereby completing the installation of a single shutter. According to the size of the ship, multiple shutters are installed between the deck 5 and the side plate 4. At the bow of the ship, a corresponding outer frame 1 is set according to the arc shape of the bow of the ship, and they are spliced, thereby replacing the traditional railing design, which is light and beautiful, and is integrated with the overall aesthetic effect of the hospital ship, thereby improving the overall aesthetics.

[0037] The inclination angle of adjacent louver blades 3 can be adjusted according to actual needs. At this time, the U-shaped rod 29 is pulled to disengage one end of the U-shaped rod 29 from the magnet 28, and the U-shaped rod 29 is removed to release the limit of the turntable 16. The adjusting shaft 15 is driven by rotating the turntable 16 to rotate the active bevel gear 18. The active bevel gear 18 is meshed with the driven bevel gear 19 to drive the rotating shaft 2 to rotate. The rotating shaft 2 drives the connecting gear 14 thereon to rotate, so that the transmission gear 17 rotates. Under the transmission of the transmission gear 17, multiple connecting gears 14 are rotated at the same time, thereby driving multiple rotating shafts 2 to rotate at the same time, adjusting the inclination angle between each louver blade 3, thereby adjusting the opening and closing degree of the louver blade 3. After the adjustment is completed, the U-shaped rod 29 is inserted so that the magnet 28 adsorbs the U-shaped rod 29 to limit the turntable 16.

[0038] When adjusting the opening and closing degree of the louver 3, the opening and closing degree of multiple adjacent louver slats 3 can be adjusted at the same time. At this time, the U-shaped rod 29 is removed, and the pull plate 25 is pulled outward to stretch the second spring 23, and the limiting rod 24 is disengaged from the inside of the limiting hole 26, and the sleeve plate 27 is pulled to extend one end of the rectangular rod 21 and deform the first spring 22. One end of the rectangular rod 21 is inserted into the rectangular groove 20. At this time, the pull plate 25 is released, and the second spring 23 is reset, so that the limiting rod 24 is inserted into the corresponding limiting hole 26, and the rotating shaft 2 and the rectangular rod 21 are limited, thereby connecting the rotating shaft 2 at the middle end of the two adjacent louver slats. Therefore, when adjusting the opening and closing degree of the louver slats 3 in one louver, the opening and closing degree of the louver slats 3 in the two adjacent louvers can also be adjusted, thereby increasing the convenience of using the louver.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
