[0028] Example 1

[0029] like Figure 1 、 Figure 2 、 Figure 3 As shown, an embodiment of the present application provides a life raft device that can be used in combination, which includes two square life raft bodies 100, each life raft body 100 is provided with a regular quadrangular pyramid-shaped awning 110, each side of the life raft body 100 corresponds to each side of the awning 110 one by one, and each of the four sides of the awning 110 is provided with an opening 120, and each side of the life raft body 100 is provided with a pair of spaced male buckles 130 and female buckles 140, the male buckle 130 and female buckle 140 on one side of the life raft body 100 are respectively used for detachable engagement with the corresponding female buckle 140 and male buckle 130 on one side of an adjacent life raft body 100, each side of the life raft body 100 is connected to a throwing cable 150, and each side of the life raft body 100 is connected to four cable fixing buckles 160 for the throwing cables 150 on the adjacent life raft bodies 100 to pass through and connect. In this embodiment, the male buckle 130 and the female buckle 140 are lock buckles that can cooperate with each other and be detachably connected.

[0030] The life raft device provided in the embodiment of the present application is composed of two square life raft bodies 100. When the rescued persons start to inflate the two life raft bodies 100 at different evacuation points, the rescued persons can board the two life raft bodies 100 and throw the throwing ropes 150 connected to the adjacent sides through the openings 120 on the corresponding sides of the awning 110 to the other life raft body 100, so that the persons on the two life raft bodies 100 can grab the throwing ropes 150 and pull them to make the two life raft bodies 100 close to each other. The life raft body 100 is connected to the female buckle 140 and the male buckle 130 at the same time, so that the rescued person can connect the male buckle 130 and the female buckle 140 on one side of the life raft body 100 with the female buckle 140 and the male buckle 130 on the other side of the life raft body 100 to form a whole, thereby effectively improving the stability and wind and wave resistance of the life raft body 100. An opening 120 is provided on each of the four sides of the awning 110, so that the rescued person can conveniently enter and exit through the openings 120 on the four sides of the awning 110 and move between the awnings 110 of the two life raft bodies 100.

[0031] Among them, each side of the liferaft body 100 is connected to four cable fixing buckles 160. The person to be rescued can pass the throwing cable 150 connected to the side of one liferaft body 100 through the cable fixing buckles 160 on the adjacent sides of two liferaft bodies 100 in sequence and then fix it to one cable fixing buckle 160 to complete the combination, so that the connection between the two liferaft bodies 100 is more stable and reliable. At the same time, after the two liferaft bodies 100 are connected together, they can be connected again with other liferaft bodies 100 to form a larger liferaft device.

[0032] In other optional embodiments, the shape of the liferaft body 100 may also be a triangle, a pentagon, or a polygon with five or more sides.

[0033] In other optional embodiments, the shape of the awning 110 may also be a triangular prism, a pentagonal prism, or a polygonal prism with five or more sides.

[0034] In other optional embodiments, each side of the awning 110 may be further provided with two or more openings 120 .

[0035] In other optional embodiments, more than two pairs of male buckles 130 and female buckles 140 may be provided on each side of the liferaft body 100 .

[0036] In other optional embodiments, each side of the liferaft body 100 may be connected to two or more throwing ropes 150 .

[0037] In other optional embodiments, two or more cable fixing buckles 160 are connected to each side of the liferaft body 100 .

[0038] Example 2

[0039] like Figure 4 As shown, the embodiment of the present application provides a life raft device that can be used in combination. Its structure is roughly the same as the life raft device that can be used in combination provided in Example 1, except that, in this embodiment, the top of each opening 120 is connected to a top shielding cloth 170 and two top connecting buckles 180, and the top shielding cloth 170 is connected to two top connecting ropes 190. The top connecting rope 190 of each top shielding cloth 170 is used to connect to the top connecting buckle 180 at the top of an opening 120 of an adjacent life raft body 100; the sides of each opening 120 are respectively connected to a side shielding cloth 200 and two side connecting buckles 210, and the side shielding cloth 200 is connected to two side connecting ropes 220. The side connecting rope 220 of each side shielding cloth 200 is used to connect to the side connecting buckle 210 on the side of an opening 120 of an adjacent life raft body 100.

[0040] The life raft device that can be used in combination provided by the embodiment of the present application is that after the two life raft bodies 100 are connected into a whole through the corresponding male buckles 130 and female buckles 140 and the throwing rope 150 that passes through and connects the four cable fixing buckles 160, it is convenient for the rescued person to pull up the top shielding cloth 170 provided on the top of the opening 120 of one life raft body 100 to a horizontal arrangement, and then connect and fix it with the top connecting buckles 180 provided on the top of the adjacent opening 120 of the other life raft body 100 through the two top connecting ropes 190, thereby forming a horizontal shielding cloth above the adjacent openings 120 of the awnings 110 of the two life raft bodies 100. When the openings 120 adjacent to the awnings 110 of the liferaft body 100 are moved, the top shielding cloth 170 is used to block rain. At the same time, it is convenient for the rescued person to pull up the side shielding cloth 200 provided on both sides of the opening 120 of one liferaft body 100 and connect and fix it with the side connecting buckles 210 provided on the sides of the adjacent opening 120 of the other liferaft body 100 through two side connecting ropes 220. In this way, the top shielding cloth 170 and the two side shielding cloths 200 are used to enclose a passage connecting the adjacent openings 120 of the awnings 110 of the two liferaft bodies 100, effectively protecting the people moving through the adjacent openings 120 of the awnings 110 of the two liferaft bodies 100.

[0041] In other optional embodiments, the number of top connecting buckles 180 connected to each opening 120 and the number of top connecting ropes 190 connected to the top shielding cloth 170 can also be one, three or more than four.

[0042] In other optional embodiments, the number of side connecting buckles 210 connected to each opening 120 and the number of side connecting cords 220 connected to the side shielding cloth 200 can also be one, three, or more than four.

[0043] An embodiment of the present application also provides an airdrop lifesaving system, which includes the above-mentioned life raft device that can be used in combination.

[0044] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
