Therefore, the following detailed implementation modes and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0040] Embodiment 1:

[0041] With key reference to Figure 1-8 , the binding master belt 6 and the binding sub-belt 7 are respectively fixedly connected to both sides of the life jacket body 1, and the binding master belt 6 and the binding sub-belt 7 cooperate to fixedly install the life jacket body 1 on the person.

[0042] A plurality of notches 25 for placing the hot compress patch mounting strip 21 and the hot compress patch 22 are provided on the inner side of the life jacket body 1. Each group of hot compress patches 22 enters from one hot compress patch 22, and can also be removed from the notch 25 subsequently. The provided plug plate 26 can seal the notch 25. The notch 25 is an internal thread groove, and the plug plate 26 is screw-shaped and can seal the notch 25. A plurality of hot compress patches 22 are evenly installed on the hot compress patch mounting strip 21.

[0043] The inside of the life jacket body 1 is a hollow cavity 8, and at least four mouth-shaped fixing plates 13 are fixedly installed in the cavity 8. The mouth-shaped fixing plates 13 are boxes with openings on both the left and right sides, and are made of lightweight rigid materials. At least two mouth-shaped fixing plates 13 can be placed in front of the chest of a person, and at least two mouth-shaped fixing plates 13 can be placed on the back of the person. One side of the opening is located inside the life jacket body 1, and the other side of the opening is on the outside of the life jacket body 1. A threaded rod 12 is hermetically and rotationally connected to the top and bottom of the mouth-shaped fixing plate 13, and one end of the threaded rod 12 extending outside the life jacket body 1 is fixedly connected to a screwing column 10. A first limiting sliding plate 18 is limited and slidably connected in the vertical groove limiting groove on the inner wall of the mouth-shaped fixing plate 13. The outer wall of the threaded rod 12 is threadedly connected to the first limiting sliding plate 18. A V-shaped groove 20 is formed on the first limiting sliding plate 18, and a C-shaped groove 17 is formed on the mouth-shaped fixing plate 13. The C-shaped groove 17 is composed of two horizontal grooves and one vertical groove. The C-shaped groove 17 and the V-shaped groove 20 cooperate to limit and slidably connect a third rotating column 28. The outer wall of the third rotating column 28 is connected to a moving plate 27, and the moving plate 27 is frictionally connected to the first limiting sliding plate 18 through a rubber layer on its outer wall. The right side of the moving plate 27 is fixedly connected to an elastic member mounting plate 31. The elastic member mounting plate 31 is connected to a first sliding sleeve 29 through a first elastic member 30. The first sliding sleeve 29 is limited and slidably connected to the outer wall of the elastic member mounting plate 31. A card slot 32 is formed on one side of the first sliding sleeve 29 away from the elastic member mounting plate 31, and a first magnet 33 is fixedly installed in the card slot 32.

[0044] When the third rotating column 28 is placed on the right side of the lower horizontal groove of the C-shaped groove 17, at this time, the first sliding sleeve 29 moves out from the notch 25 on the inner side of the life jacket body 1. At this time, the second magnet 34 on one side of the top of the hot compress patch mounting strip 21 is inserted into the card slot 32 and adsorbs with the first magnet 33. Then rotate the screwing column 10 to make the threaded rod 12 rotate. Then make the first limiting sliding plate 18 perform a C-shaped movement, so that the hot compress patch mounting strip 21 and the hot compress patch 22 are moved into the life jacket body 1 and pressed against the inner wall of the cavity 8 close to the inner side of the life jacket body 1. Multiple hot compress patch mounting strips 21 pressed against the inner wall of the cavity 8 on the inner side of the life jacket body 1 fix the life jacket body 1 on the body of the person, so that the hot compress patch 22 is relatively attached to the person. And the provided mouth-shaped fixing plate 13, when an external object hits the life jacket body 1 and cooperates with the buffering of the first elastic member 30, prevents the person from being injured.

[0045] Embodiment 2: On the basis of Embodiment 1, after the hot compress patch mounting strip 21 and the hot compress patch 22 are installed, they can be better attached to the cavity 8 close to the inner side of the life jacket body 1.

[0046] Key reference Figure 9, on the side of the first limit sliding plate 18 away from the notch 25, there are teeth 19 provided. Inside the inner wall of the mouth-shaped fixing plate 13, the first rotating column 15, the second rotating column 23, and the fourth rotating column 40 are rotatably connected. On the outer wall of the first rotating column 15, a first gear 14 is fixedly connected. The first rotating column 15 is close to the upper horizontal groove of the C-shaped groove 17. When the third rotating column 28 moves towards the upper horizontal groove of the C-shaped groove 17, at this time, the first gear 14 and the teeth 19 are engaged with each other. And a belt 16 is sleeved on the first rotating column 15 and the second rotating column 23 through pulley sets. On the outer wall of the second rotating column 23, a second gear 38 is fixedly connected. On the outer wall of the fourth rotating column 40, a third gear 39 is fixedly connected. The third gear 39 and the second gear 38 are engaged with each other. On the outer wall of the fourth rotating column 40, a rotating bar 24 is fixedly connected. At the end of the rotating bar 24, a second elastic member 36 is connected to a second sliding sleeve 35. The second sliding sleeve 35 is slidably connected to the outer wall of the rotating bar 24 in a limited manner. On the side of the second sliding sleeve 35 away from the rotating bar 24, an arc-shaped plate 37 is fixedly connected. The arc-shaped plate 37 straightens the hot compress patch mounting strip 21 first and then fixes it elastically, so that each hot compress patch 22 can better adhere to the person's body.

[0047] Other structures of this embodiment are the same as those of the first embodiment.

[0048] Embodiment 3: On the basis of Embodiment 2, it is made safer for the person in water.

[0049] Focus on reference Figure 1 and Figure 3 , the hot compress patch 22 is an object like a warming patch, which generates heat by the contact of iron powder with air. A certain amount of oxygen needs to be consumed. On the left and right shoulders of the life jacket body 1, an air tube 9 is connected to each. On the side of the air tube 9 away from the life jacket body 1, a balloon body 4 is connected. On the outer wall of the balloon body 4, a reflective strip 5 is provided. The two balloon bodies 4 are symmetrically installed on both sides of the head placement floating member 2, and a head limit block 3 is installed in the middle of the head placement floating member 2 for the person's head to be placed on it. The person can know that they are discovered through the reflection of the reflective strip 5 and then move violently, so that the rescuers can better judge the position of the person to be rescued. And the two balloon bodies 4 can also prevent external objects from hitting the person's head and protect the person. And it can be judged whether the hot compress patch 22 has been consumed and whether a new hot compress patch 22 needs to be replaced through the inflation degree of the balloon body 4. The inflation degree of the balloon body 4 is also convenient for the person falling into the water to judge the available time of the hot compress patch 22 and is convenient for better judging the subsequent self-rescue time.

[0050] In a specific implementation, first, open the notch 25 of the life jacket body 1, and then tear the hot compress patch 22 and evenly paste it on the hot compress patch installation strip 21. Then rotate the screw rod 12 by turning the screw rod 10. At this time, with the cooperation of the thread and the limit, the first limit sliding plate 18 moves downward. Then, under the cooperation of the V-shaped groove 20 and the U-shaped groove 17, the first sliding sleeve 29 moves out of the notch 25. At this time, the second magnet 34 at the end of the hot compress patch installation strip 21 is inserted into the card slot 32 of the first sliding sleeve 29 and then adsorbs and fixes with the first magnet 33. At this time, reverse the screw rod 10 to make the first limit sliding plate 18 move upward. Then, when the V-shaped groove 20 and the U-shaped groove 17 cooperate, when the V-shaped groove 20 moves to the upper horizontal groove of the U-shaped groove 17, the teeth 19 on the first limit sliding plate 18 mesh with the first gear 14. At this time, under the action of the first elastic member 30, the first sliding sleeve 29 presses the upper part of the hot compress patch installation strip 21 against the inner wall of the cavity 8 near the inside of the life jacket body 1, so that the hot compress patch 22 is pasted on the person's body. This side has no notch-shaped fixing plate 13 and can be well pasted on the person's body. And at this time, the first rotating column 15 and the second rotating column 23 are sleeved together through a pulley, so that the second rotating column 23 and the first rotating column 15 rotate synchronously. Then, the second gear 38 and the third gear 39 mesh with each other, so that the rotating strip 24 placed on the outer wall of the fourth rotating column 40 rotates onto the hot compress patch installation strip 21, so that the arc plate 37 pulls the hot compress patch installation strip 21 to make the hot compress patch installation strip 21 vertical. Then finally, under the action of the second elastic member 36, the arc plate 37 presses the bottom of the hot compress patch installation strip 21. Thus, multiple hot compress patches 22 are closely pasted on the person's body for heat conduction. Then block the notch 25 with the plug plate 26. Then inflate the 08 through the 11. The oxygen content of the inflated gas is selected according to actual requirements.

[0051] Moreover, the heat generation process of the hot compress patch 22 consumes air. At this time, the balloon body 4 becomes smaller. And there are ventilation holes provided on the notch-shaped fixing plate 13, that is, the cavity 8 and the two balloon bodies 4 have the same air pressure. At this time, the head placement float 2 will maintain a stable state so that the person's head can be safely placed, and the buoyancy is greater. The degree to which the balloon body 4 becomes smaller is convenient for the person to judge whether the hot compress patch 22 has been used for a period of time and to judge whether it needs to be replaced. The provided reflective strip 5 is convenient for the person to discover the position of the person who has fallen into the water, and it is also convenient for the person who has fallen into the water to discover that they may be discovered. More intense movements enable the rescue personnel to determine that it is a person who has fallen into the water.

[0052] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
