[0019] See also Figure 1 and Fig.10 , which is a schematic diagram of the overall structure of the present application, the device includes a lifeboat body 10, a lifesaving mechanism 20 is arranged on the side of the lifeboat body 10, and the lifesaving mechanism 20 can rotate on the side of the lifeboat 10. When in use, the angle between the lifesaving mechanism 20 and the lifeboat body 10 is changed to make them perpendicular to each other, and the lifesaving mechanism 20 falls into the seawater; when not in use, the lifesaving mechanism 20 is kept parallel to the long side of the lifeboat body 10. In this embodiment, by changing the angle between the lifesaving mechanism 20 and the lifeboat body 10, the two states of normal use of the lifeboat and emergency rescue of the lifeboat can be quickly switched.

[0020] Further, such as Figure 2-4 As shown, the lifesaving mechanism 20 includes a fixed gear 21 fixedly mounted on the side of the lifeboat body 10, and a lifesaving board 22 coaxially designed with the fixed gear 21 is provided on the side of the lifeboat body 10. The lifesaving board 22 can rotate on the side of the lifeboat body 10, and the internal rotation of the lifesaving board 22 is connected to a connecting gear 23 meshing with the fixed gear 21. When the lifesaving board 22 rotates on the side of the lifeboat body 10, the connecting gear 23 cooperates with the meshing connection to rotate inside the lifesaving board 22. In this embodiment, a limit groove is provided on the rotation axis of the lifesaving board 22. By inserting the corresponding rotating handle into the limit groove, the rotation of the lifesaving board 22 can be controlled. After adjusting the angle, the rotating handle is pulled out from the limit groove. By adjusting the lifesaving board 22 to be perpendicular to the lifeboat body 10, the lifesaving board 22 can be placed below the sea level. During emergency rescue, the drowning person can hold the lifesaving board 22 to recover his strength. Fig. 9As shown, when the life-saving board 22 is in a horizontal state, the angle of the life-saving board 22 can be fixed by setting a limiting mechanism on the lifeboat body 10.

[0021] However, because the lifeboat body 10 is surrounded by enclosures with a certain height, if the drowning person wants to climb onto the lifeboat, it takes a lot of effort, which is very difficult for the drowning person. Therefore, in response to this problem, the present application has also made the following improvements.

[0022] like Figure 4 and Figure 5 As shown, the lifesaving board 22 is provided with a plurality of pedals 24, and a drowning person can climb up by stepping on the pedals 24, which is more conducive to the drowning person or rescuer who has exhausted his physical strength to climb onto the lifeboat.

[0023] like Figure 6 As shown, further, a groove body 25 is provided inside the lifesaving board 22, and a cavity 26 for the connection gear 23 to rotate is provided at the upper end of the groove body 25, and a connecting mechanism 30 is arranged inside the groove body 25, and the connecting mechanism 30 includes a connecting rod 31 that reciprocates inside the groove body 25, and the connecting rod 31 penetrates the groove body 25 to the cavity 26 and is connected to a movable guide rod 32, and the other end of the movable guide rod 32 is rotatably connected to the eccentric part of the connection gear 23, and a movable rod 33 is hinged on the side of the connecting rod 31, and the other end of the movable rod 33 is connected to the pedal 24, and the pedal 24 is hinged on the side of the lifesaving board 22, and a guide groove 241 is provided inside the pedal 24, and a guide rod 242 is fixedly installed inside the guide groove 241, and a sliding block 243 is slidably connected to the guide rod 242, and the sliding block 243 is hinged to the movable rod 33. In this embodiment, when the lifeboard 22 changes from a horizontal angle to a vertical angle with the lifeboat, the connecting gear 23 rotates on the fixed gear 21, and the movable guide rod 32 drives the connecting rod 31 to move from top to bottom inside the groove 25 (the top refers to the end face close to the fixed gear 21), and then cooperates with the action of the upper movable rod 33 to drive the pedal 24 hinged on the lifeboard 22 to rotate. When the lifeboard 22 is in a vertical state, the pedal 24 is in a horizontal state (i.e., perpendicular to the lifeboard 22), so that when the lifeboard 22 is lowered, the pedal 24 can also be simultaneously unfolded to provide support for the drowning person or rescuer, thereby achieving a quick rescue effect.

[0024] On the contrary, when the life-saving board 22 needs to be folded up, the life-saving board 22 is reversed (rotated counterclockwise), and the connecting gear 23 on the fixed gear 21 also rotates in the opposite direction. At this time, the movable guide rod 32 drives the connecting rod 31 to move from bottom to top inside the groove body 25, and with the cooperation of the movable rod 33, the pedal 24 can be folded up, achieving the effect of quick storage and sorting.

[0025] When the drowning person or rescuer climbs onto the lifeboat body 10, a force will be applied to the lifeboat board 22 each time the pedal 24 is pressed hard, and the lifeboat body 10 will suddenly sink, causing the lifeboat to shake. In order to reduce the sinking amplitude of the lifeboat body 10, the present application also makes the following improvements.

[0026] like Figure 7 , Figure 8 and Fig. 9 As shown, a buffer mechanism 40 is provided at the lower end of the connecting rod 31, and the buffer mechanism 40 includes a moving rod 41 hinged to the connecting rod 31, and the buffer mechanism 40 also includes a placement chamber 42 opened at the bottom of the lifesaving board 22, and a sliding rod 46 is fixedly installed inside the placement chamber 42, and the moving rod 41 moves on the sliding rod 46 through a sliding ring 43, and the moving rod 41 is hinged to the sliding ring 43, and an inflatable cylinder 44 is slidably provided on the inner side walls of the placement chamber 42, and the inflatable cylinder 44 includes a fixed cylinder and a piston rod, and the piston rod is movably connected to the bottom of the moving rod 41, and the bottom of the sliding ring 43 is connected to an elastic air plate 45, and the inflatable cylinder 44 is connected to the elastic air plate 45 through a connecting hose. In this embodiment, when the connecting rod 31 moves downward inside the lifesaving board 22, the moving rod 41 will be driven to move downward, and the moving rod 41 will move along the sliding rod 46 under the action of the sliding ring 43. At this time, the bottom of the moving rod 41 has two movements, one is downward movement, and the other is movement to both sides inside the placement chamber 42. When moving to both sides, the piston rod will be cooperated to push out the gas inside the fixed cylinder, and the gas will enter the elastic gas plate 45 through the connecting hose. After the elastic gas plate 45 obtains the gas, the volume will increase, that is, as the moving rod 41 moves on the sliding rod 46, the volume of the elastic gas plate 45 gradually increases, and because the sliding ring 43 has a vertical movement, the elastic gas plate 45 placed inside the placement chamber 42 will be pushed out of the cavity. That is, after the above-mentioned action is completed, the elastic gas plate 45 filled with gas will appear below the lifesaving board 22.

[0027] The elastic air plate 45 below the lifeboat board 22 will, due to the existence of buoyancy, act as a barrier to the drowning person or rescuer to apply force to the lifeboat when climbing, thereby reducing the sinking amplitude of the lifeboat and increasing the stability of the lifeboat during the rescue process.

[0028] Likewise, when the lifesaving board 22 is retracted (in a parallel state with the lifeboat), the gas in the elastic gas board 45 filled with gas will be pumped out and placed in the placement chamber 42 for storage.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
