[0002] A life raft is a device used to provide survival and escape when a ship is in distress. Typically, a life raft is an inflatable device with good buoyancy that can float on the water and provide a refuge for the occupants. A life raft usually carries basic survival equipment to help the occupants survive at sea for a period of time until they are rescued.

[0003] In the prior art, a life raft is placed on the water surface and then expanded by inflating it, thereby expanding the roof of the life raft. A buoyancy bar is fixed to the bottom of the life raft, which can be used to right the tilted life raft. Metal pull rings fixed around the life raft can be used for lifting. When the life raft is fully expanded, the staff will support and fix the roof with a bracket set in the center of the life raft.

[0004] However, when the life raft is inflated, the roof also needs to be inflated, which results in a long working time for the life raft to be fully inflated. In addition, the support frame is arranged in the center of the life raft, and the support frame occupies the usable space of the life raft when supporting and fixing it, thereby affecting the use effect of the life raft. Utility Model Content

[0005] The purpose of the utility model is to provide a suspendable self-righting inflatable life raft to solve the technical problems in the prior art that when the life raft is inflated, the roof also needs to be inflated, which leads to a long working time for the life raft to be fully inflated, and the support frame is arranged in the center of the life raft. When the support frame is supported and fixed, the usable space of the life raft is occupied, thereby affecting the use effect of the life raft.

[0006] The technical problem to be solved by the present invention can be achieved through the following technical solutions:

[0007] A hoistable self-righting inflatable life raft comprising:

[0008] A life raft, wherein a plurality of bottom plates are axially fixedly connected to the top of the life raft, and a support shaft is fixedly connected to the inner wall of the bottom plate;

[0009] The support frame has a side end sleeved and connected to the support shaft, a slide groove is provided on the top of the support frame along the length direction, and a limiting groove is provided on the side end of the support frame away from the bottom plate;

[0010] The slide is clamped in the slide groove and is slidably connected to the slide groove. The top of the slide is cooperatively connected with a pull plate, and the top of the pull plate is fixedly connected with a roof.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0028] As Figures 1-6 shown, a hoistable self - righting inflatable life raft includes: a life raft 1, a support frame 5, and a sliding seat 8,

[0029] A plurality of bottom plates 2 are axially and fixedly connected to the top of the life raft 1. A support shaft 11 is fixedly connected to the inner wall of the bottom plate 2. When the life raft 1 is placed on the water surface for inflation, since the present utility model removes the inflatable canopy top, the inflation time of the life raft 1 is reduced, thereby improving the working efficiency of using the life raft 1. Among them, the bottom plate 2 is used to provide support and limit functions;

[0030] The side end of the support frame 5 is sleeved and connected to the support shaft 11. A chute 6 is provided at the top of the support frame 5 along the length direction. A limit groove 7 is provided at the side end of the support frame 5 away from the bottom plate 2. When the support frame 5 is opened around, the side end of the support frame 5 rotates around the support shaft 11. It should be noted that the bottom end of the support frame 5 can be fixed with a shielding plastic material in the prior art. When the support frame 5 is perpendicular to the life raft 1, the support frame 5 opens the shielding plastic material, so as to achieve the effect of the shielding plastic material opening on the life raft 1;

[0031] The sliding seat 8 is clamped in the chute 6 and is slidably connected to the chute 6. A pulling plate 3 is connected to the top end of the sliding seat 8 in a matching manner. A canopy 4 is fixedly connected to the top end of the pulling plate 3. In order to enable multiple support frames 5 to rotate simultaneously, the pulling plate 3 moves upward. The pulling plate 3 controls the sliding of the sliding seat 8 in the chute 6. The chute 6 pulls the support frame 5 to rotate. When the support frame 5 is perpendicular to the top of the life raft 1, the sliding seat 8 is moved into the limit groove 7. At this time, the pulling plate 3 is located at the top of the support frame 5. The canopy 4 fixed to the top of the pulling plate 3 can play a role of shielding and protection. Compared with the fixed support, the operation of the support frame 5 is convenient. At the same time, the use of the space of the life raft 1 by the support is avoided, and the space utilization efficiency of the top of the life raft 1 is improved.

[0032] In some specific implementation schemes, a holding groove 17 is provided on the inner wall of the bottom plate 2. A positioning column 14 is fixedly connected to the side end of the bottom plate 2. A limiting plate 16 is slidably connected to the positioning column 14 in a direction perpendicular to the support frame 5. A positioning hole 15 is provided along the axis of the positioning column 14 on the limiting plate 16. A spring 13 is provided between the limiting plate 16 and the bottom plate 2. The spring 13 is sleeved on the positioning column 14 and is fixedly connected to the bottom plate 2 and the limiting plate 16 at both ends respectively. The positioning column 14 is slidably connected to the positioning hole 15. The limiting plate 16 is connected to the holding groove 17 in a limiting manner. The limiting plate 16 is connected to the support frame 5 in a holding manner. In order to enable the support frame 5 to be fixed after being perpendicular to the top of the life raft 1 and avoid the phenomenon of rotational loosening of the support frame 5 on the bottom plate 2. When the support frame 5 rotates along the inner wall of the bottom plate 2, the limiting plate 16 abuts against the support frame 5. When the support frame 5 is perpendicular to the life raft 1, the support frame 5 releases the limiting effect on the limiting plate 16. The limiting plate 16 slides under the action of the pulling force of the spring 13. The limiting plate 16 is inserted into the holding groove 17. The spring 13 maintains a pulling and limiting effect on the limiting plate 16. The limiting plate 16 abuts against and limits the support frame 5, ensuring that the support frame 5 will not rotate. Among them, the spring 13 runs on the positioning column 14. On the one hand, the positioning column 14 supports the spring 13 to avoid the phenomenon of bending of the spring 13. On the other hand, the positioning column 14 positions and guides the limiting plate 16 to ensure the stability of the sliding of the limiting plate 16.

[0033] In some specific embodiments, the sliding groove 6 communicates with the limiting groove 7, and the limiting groove 7 is in limiting connection with the sliding seat 8. When the sliding seat 8 slides along the sliding groove 6, when the sliding seat 8 slides close to the limiting groove 7, the sliding seat 8 turns along the inner wall where the sliding groove 6 and the limiting groove 7 are connected. When the sliding seat 8 moves in the limiting groove 7 and abuts against the limiting groove 7, the limiting and supporting effect provided by the support frame 5 is transmitted to the pulling plate 3 through the limiting connection between the sliding seat 8 and the limiting groove 7.

[0034] In some specific embodiments, connecting plates 10 are rotatably connected to both ends of the sliding seat 8 respectively. A connecting shaft 9 is provided between the two groups of connecting plates 10. The connecting shaft 9 is rotatably connected to the inner wall of the sliding seat 8 and is fixedly connected to the connecting plates 10 at both ends respectively. The top ends of the connecting plates 10 are fixedly connected to the pulling plate 3. To ensure that the pulling plate 3 drives the support frame 5 to rotate through the sliding seat 8, when the sliding seat 8 moves in the sliding groove 6, the connecting plates 10 rotate in the sliding seat 8 through the connecting shaft 9, so as to ensure that the pulling plate 3 can drive the sliding seat 8 to move without getting stuck.

[0035] In some specific embodiments, a support hole 12 is formed in the side end of the support frame 5. Both ends of the support frame 5 are rotatably connected to the inner wall of the bottom plate 2. The support shaft 11 is rotatably connected to the support hole 12. To ensure that the support frame 5 can rotate stably, when the support frame 5 rotates, the support hole 12 formed in the support frame 5 rotates around the support shaft 11. Among them, the bottom plate 2 limits both ends of the support frame 5 to prevent the support frame 5 from shifting.

[0036] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as used to limit the implementation scope of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
