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.

[0033] It should be further noted that when installing the shutter at the bow of the ship, according to the arc of the ship's bow, the corresponding outer frame 1 is set and spliced, as Figure 7 , so as to adapt to the bow of the ship and increase the aesthetics.

[0034] Bearings are provided at the joints of several rotating shafts 2 and the outer frame 1, and the rotating shafts 2 are fixed to the inner rings of the bearings. In this embodiment, by setting the bearings, the rotating shafts 2 are facilitated to rotate.

[0035] Both the outer frame 1 and the shutter blades 3 are made of aluminum. In this embodiment, the tooling is made of aluminum material, which is relatively light and beautiful.

[0036] In the specific implementation process, according to the length of the medical ship, the number of shutters to be installed is selected. When installing the shutters, the top support ear plates 6 and the bottom support ear plates 11 are respectively welded to the top and bottom of the outer frame 1, and the top support feet 7 and the bottom support feet 10 are welded to the opposite outer surfaces of two adjacent decks 5.

[0037] Embodiment 2:

[0038] Please refer to Figures 8-10 , connection gears 14 are fixedly sleeved on the outer surfaces of several rotating shafts 2. The rear outer surface of the left end of the outer frame 1 is rotatably penetrated by an adjusting shaft 15. A turntable 16 is fixedly connected to the outer surface of the adjusting shaft 15 located outside the outer frame 1. A driving bevel gear 18 is fixedly sleeved on the outer surface of the adjusting shaft 15 far from the turntable 16. A driven bevel gear 19 is fixedly sleeved on the outer surface of the left end of the middle rotating shaft 2. The outer surfaces of the driving bevel gear 18 and the driven bevel gear 19 are movably meshed. In this embodiment, rotating the turntable 16 drives the adjusting shaft 15 to make the driving bevel gear 18 rotate. The driving bevel gear 18 meshes with the driven bevel gear 19 to drive the rotating shaft 2 to rotate, and the rotating shaft 2 drives the connection gears 14 thereon to rotate.

[0039] A number of support shafts are rotatably connected to the left inner surface of the outer frame 1. Transmission gears 17 are fixedly sleeved on the outer surfaces of the a number of support shafts. The a number of transmission gears 17 are respectively in movable meshing with the outer surfaces of the upper and lower adjacent connecting gears 14. In this embodiment, when the middle rotating shaft 2 rotates, it drives the connecting gear 14 on it to rotate. With the cooperation of the transmission gears 17, the multiple connecting gears 14 cause the rotating shaft 2 to change by the same angle.

[0040] A magnet 28 is fixedly connected to the outer surface of the rear side of the left end of the outer frame 1 around the adjusting shaft 15. A U-shaped rod 29 is fixedly connected to the outer surface of the turntable 16. The U-shaped rod 29 is an iron rod, and the U-shaped rod 29 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. With the meshing force between each gear and the meshing force between the driving bevel gear 18 and the driven bevel gear 19, the shutter blades 3 are prevented from rotating independently.

[0041] A sleeve disk 27 is fixedly sleeved on the outer surface of the rectangular rod 21. The diameter of the sleeve disk 27 is larger than the diameter of the rectangular rod 21. In this embodiment, since the diameter of the sleeve disk 27 is larger than the diameter of the rectangular rod 21, when it is necessary to pull the rectangular rod 21, the sleeve disk 27 provides a force application point for the adjuster, facilitating the pulling of the rectangular rod 21.

[0042] In the specific implementation process, according to actual needs, adjust the inclination angle of adjacent shutter blades 3. At this time, pull the U-shaped rod 29 so that one end of the U-shaped rod 29 disengages from the magnet 28, remove the U-shaped rod 29, release the limit on the turntable 16, drive the adjusting shaft 15 by rotating the turntable 16 to make the driving bevel gear 18 rotate. The driving bevel gear 18 meshes with the driven bevel gear 19 to drive the rotating shaft 2 to rotate. The rotating shaft 2 drives the connecting gear 14 on it to rotate, causing the transmission gears 17 to rotate. Under the transmission of the transmission gears 17, the multiple connecting gears 14 rotate simultaneously, thereby driving the multiple rotating shafts 2 to rotate simultaneously, adjusting the inclination angle between each shutter blade 3, and thus adjusting the opening and closing degree of the shutter blades 3. After adjustment, insert the U-shaped rod 29 so that the magnet 28 adsorbs the U-shaped rod 29 to limit the turntable 16.

[0043] Embodiment 3:

[0044] Please refer to Figures 10-11 On the left outer surface of the middle rotating shaft 2, a rectangular groove 20 is provided. 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. 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.

[0045] A limiting rod 24 is movably inserted on the outer surface of the middle rotating shaft 2. A pulling 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 middle rotating shaft 2. The other end of the second spring 23 is fixedly connected to the outer surface of the pulling plate 25. A plurality of limiting holes 26 arranged in a linear array are formed on the outer surface of the rectangular rod 21. In this embodiment, when the pulling plate 25 is pulled outwards, the second spring 23 is stretched, and the limiting rod 24 disengages from the inside of the limiting hole 26, releasing the limit on the rectangular rod 21, so as to adjust the position of the rectangular rod 21. After the adjustment is completed, the pulling plate 25 is released, and the second spring 23 resets, causing the limiting rod 24 to insert into the corresponding limiting hole 26 to limit the rotating shaft 2 and the rectangular rod 21.

[0046] An adjustment notch 30 is formed on the right outer surface of the outer frame 1, and a connection notch 31 is formed 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 through the connection notch 31, one rectangular rod 21 can extend in from the connection notch 31 to connect the two rotating shafts 2.

[0047] It should be further noted that when multiple outer frames 1 are spliced, the connection notch 31 can be cancelled for the leftmost outer frame 1, and the adjustment notch 30 can be cancelled for the rightmost one, which improves the aesthetics.

[0048] In the specific implementation process, when adjusting the opening and closing degree of the louver blades 3, the opening and closing degrees of multiple adjacent louver blades 3 can be adjusted simultaneously. At this time, the U-shaped rod 29 is removed, the pulling plate 25 is pulled outwards to stretch the second spring 23, and the limiting rod 24 disengages from the inside of the limiting hole 26. The sleeve plate 27 is pulled to extend one end of the rectangular rod 21, deforming the first spring 22. One end of the rectangular rod 21 is inserted into the rectangular groove 20. At this time, the pulling plate 25 is released, and the second spring 23 resets, causing the limiting rod 24 to insert into the corresponding limiting hole 26 to limit the rotating shaft 2 and the rectangular rod 21, thereby connecting the middle rotating shafts 2 in two adjacent louvers. Thus, when adjusting the opening and closing degree of the louver blades 3 in one louver, the opening and closing degrees of the louver blades 3 in two adjacent louvers can also be adjusted, increasing the convenience of using this louver.

[0049] Working principle: In the actual use process of the utility model, according to the length of the medical ship, the number of installed louvers is selected. When installing the louvers, 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 two adjacent decks 5. 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 through the top nut 9. 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 through the bottom nut 13, thus completing the installation of a single louver. According to the size of the ship, multiple louvers are installed between the deck 5 and the side plate 4. At the bow of the ship, according to the arc of the bow of the ship, the corresponding outer frame 1 is set and spliced, thus replacing the traditional railing design, being light and beautiful, and integrating with the overall aesthetic effect of the hospital ship, improving the overall aesthetics.

[0050] The inclination angle of adjacent louver blades 3 can be adjusted according to actual needs. At this time, pull the U-shaped rod 29 so that one end of the U-shaped rod 29 disengages from the magnet 28, remove the U-shaped rod 29, release the limit on the turntable 16, drive the adjusting shaft 15 by rotating the turntable 16 to make the driving bevel gear 18 rotate. The driving bevel gear 18 meshes 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, making the transmission gear 17 rotate. Under the transmission of the transmission gear 17, multiple connecting gears 14 rotate simultaneously, thereby driving multiple rotating shafts 2 to rotate simultaneously, adjusting the inclination angle between the louver blades 3, and thus adjusting the opening and closing degree of the louver blades 3. After the adjustment is completed, insert the U-shaped rod 29 so that the magnet 28 adsorbs the U-shaped rod 29 to limit the turntable 16.

[0051] When adjusting the opening and closing degree of the louver blades 3, the opening and closing degrees of the louver blades 3 of multiple adjacent louvers can be adjusted simultaneously. At this time, remove the U-shaped rod 29, pull the pull plate 25 outwards to stretch the second spring 23, and the limit rod 24 disengages from the inside of the limit hole 26. Pull the sleeve plate 27 to make one end of the rectangular rod 21 extend, and the first spring 22 deforms. Insert one end of the rectangular rod 21 into the rectangular groove 20. At this time, release the pull plate 25, and the second spring 23 resets to make the limit rod 24 insert into the corresponding limit hole 26 to limit the rotating shaft 2 and the rectangular rod 21, thereby connecting the rotating shafts 2 at the middle ends of two adjacent louvers. Thus, when adjusting the opening and closing degree of the louver blades 3 in one louver, the opening and closing degrees of the louver blades 3 in two adjacent louvers can also be adjusted, increasing the convenience of using this louver.

[0052] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
