Description

Technical Field

[0001] The utility model relates to the technical field of life rafts, in particular to an inflatable life raft with stable overturning. Background Art

[0002] A life raft is a tool used for rescue on the water. The most commonly used life raft is an inflatable life raft. When in use, rescuers drive the life raft on the water and then salvage the people who fall into the water onto the life raft. In the rescue work, every minute is critical and quick rescue is important. However, for the convenience and quickness of use, small boats often use light and compact life rafts, which are prone to flipping over when in use.

[0003] When people climb onto the life raft, the circular enclosure air cushion of most life rafts is high, which is not convenient for people to climb up, and the inflatable life raft is violently shaken during the climbing process. It is difficult to rescue the people in need in time and quickly when the inflatable life raft is used for rescue. In addition, the small boat is unstable, which poses a great safety hazard and affects the rescue effect to a certain extent. Utility Model Content

[0006] As a preferred technical solution of the utility model, a fixing block is installed on the top surface of the life raft base, and a rope groove is opened inside the fixing block.

[0007] As a preferred technical solution of the utility model, a thread groove is provided inside the fixing block, a threaded nail is movably installed on the inner wall of the thread groove, and the bottom end surface of the threaded nail is in movably contact with one end surface of the pull rope.

[0008] As a preferred technical solution of the utility model, a plurality of counterweight ropes are installed on the bottom surface of the life raft base, and a counterweight ball is installed on the bottom surface of the plurality of counterweight ropes.

[0009] As a preferred technical solution of the utility model, an inflation port is provided on the outer surface of the annular enclosure air cushion, and an inflation valve is installed on the inner wall of the inflation port.

[0010] Compared with the prior art, the utility model provides a flip-stable inflatable life raft, which has the following beneficial effects:

[0011] The inflatable life raft with stable flipping has a low entrance height, which is convenient for people who fall into the sea to enter the life raft base and reduces the flipping and shaking of the life raft base. The pull rope is convenient for people at a distance to pull the pull rope and swim to the entrance. The entrance height is low, and the pull rope and the handle belt cooperate with each other, which is convenient for people who fall into the sea to enter the life raft base from the entrance.

[0012] The flip-stable inflatable life raft has a life raft base and a counterweight ball that cooperate with each other, so that the life raft base provides a stabilizing force during the flipping and shaking process and the people on the life raft base are stabilized in advance. When the pull rope is fixed in the rope groove, the outer air cushion is in active contact with the annular enclosure air cushion to prevent water waves from entering the life raft base from the entrance.
