[0024] The utility model will be described in detail below in combination with the drawings and examples.

[0025] The lifesaving position indicating buoyant belt, as shown in Figure 1 , Figure 5 , comprises a belt body 1, the belt body 1 is fixedly connected with a metal sheet 2, one end of the belt body 1 is fixedly connected with a connecting rope 3, the belt body 1 is internally provided with an air cavity 4, the belt body 1 comprises two waterproof layers, and the edges of the two waterproof layers are fixed together in a bonding mode; the waterproof layer is usually selected from nylon fabric or neoprene, and the color of the waterproof layer is selected from fluorescent color; in the daytime, the lifesaving position indicating buoyant belt can attract more attention, and rescue personnel can discover and rescue in time; the waterproof effect of the nylon fabric and the neoprene can be well satisfied, so that water is prevented from penetrating into the air cavity 4 through the belt body 1; the metal sheet 2 is bonded to the inner side of the waterproof layer; the metal sheet 2 is selected from aluminum foil or other foil bodies capable of reflecting radar waves; the metal sheet 2 reflects radar signals, so that rescue can be quickly performed in the case that the light intensity is weak at night or in other conditions, and personnel casualties are reduced; and the connecting rope 3 facilitates binding the belt body 1 on the body or on a ship; in the process of using the belt body 1, more labor can be saved, physical strength is saved, and the possibility of survival is increased.

[0026] As Figures 1-2 , Figure 5As shown, the band body 1 is fixedly connected with the air inlet pipe 5 which is communicated with the air cavity 4 on the side close to the connecting rope 3, the normal section of the air inlet pipe 5 is L-shaped, the air inlet pipe 5 is detachably connected with the sealing cover 7 at the air inlet, the sealing cover 7 is threadedly connected with the air inlet pipe 5, a plurality of anti-skid grooves 6 are formed on the outer peripheral wall of the sealing cover 7, the air inlet pipe 5 is communicated with the air cavity 4, so that the external gas is filled into the air cavity 4 through the air inlet pipe 5, and the gradually filled gas gradually expands the rolled band body 1 until the band body 1 is arched into a cylindrical shape, thereby ensuring the expansion area of the band body 1 and avoiding the cylindrical band body 1 from being arched, so that the light can be better reflected to attract the attention of the rescuers to achieve the location effect.

[0027] As shown in Figures 1-2 , the air inlet pipe 5 is also L-shaped, which reduces the height of the air inlet pipe 5 and occupies less space when the band body 1 is rolled, facilitating the storage of the band body 1, the air inlet pipe 5 is bent, so that it is more convenient and labor-saving to blow air with the mouth, and the sealing cover 7 can completely block the air inlet pipe 5 when it is completely screwed on the air inlet pipe 5, preventing the gas from flowing out and affecting the location effect of the band body 1, and the anti-skid grooves 6 on the sealing cover 7 increase the roughness of the side wall of the sealing cover 7, making it easier to unscrew the sealing cover 7.

[0028] As shown in Figures 3-5 , the air inlet pipe 5 is provided with a reactant 8, and the air cavity 4 is provided with a reactant 9 which reacts with the reactant 8 to form gas, the reactant 8 contacts with the reactant 9 after the sealing cover 7 is separated from the air inlet pipe 5, the reactant 9 is fixedly connected to the inner wall of the air cavity 4 away from the air inlet pipe 5, the reactant 8 is stored in a bag, one side of the bag is bonded to the reactant 9, and one side of the bag is fixedly connected with a pulling rope, the other end of the pulling rope is connected with the sealing cover 7.

[0029] As shown in Figures 3-5 , the reactant 8 is preferably hydrochloric acid HCl, and the bag is preferably made of polyethylene plastic material which has good resistance to hydrochloric acid corrosion, so that the bag can stably store the reactant 8, and the reactant 9 is preferably a cotton sheet containing calcium carbonate powder, the reactant 9 is bonded to the side wall of the air cavity 4 away from the air inlet pipe 5, in the normal state, the bag prevents the reactant 8 from contacting with the reactant 9, one side of the bag is bonded to the reactant 9, and the bonding area of the bag and the reactant 9 is smaller than the cross-sectional area of the reactant 9, when falling into water, the sealing cover 7 is removed and the bag is pulled away from the air cavity 4 by the pulling rope, because the bag is pulled in two directions, the bag is broken, so that the reactant 8 contacts with the reactant 9 and reacts, the reaction generates carbon dioxide which is filled in the air cavity 4, so that the band body 1 gradually expands and unfolds.

[0030] As shown in Figures 3-5As shown, the intake pipe 5 includes a normal section and a constricted section. A sealing ball 10 and an elastic element 11 are installed in the normal section. The elastic element 11 is a spring, with its two ends fixedly connected to the sealing ball 10 and the intake pipe 5, respectively. The elastic element 11 pushes the sealing ball 10 to abut against the end of the constricted section. The sealing ball 10 is a rubber ball with a diameter smaller than the inner diameter of the normal section and larger than the maximum inner diameter of the constricted section. The rubber ball has deformation properties. The elastic element 11 pushes the sealing ball 10... The 0 is blocked at the constricted section of the air intake pipe 5. The deformable rubber material can ensure a tighter fit, ensuring that even if the sealing cap 7 is not sealed, a large amount of gas will flow out of the belt body 1. This avoids the situation where the strength is exhausted during survival and it is difficult to seal the sealing cap 7, which would prevent the drifting belt from achieving the expected effect. A push rod 12 is fixedly connected to the sealing cap 7. The push rod 12 is integrally injection molded on the sealing cap 7. The push rod 12 is inserted into the air intake pipe 5 and abuts against the outer peripheral wall of the sealing ball 10. The length of the push rod 12 is greater than the length of the constricted section.

[0031] like Figures 3-5 As shown, when the float is stored, the sealing cap 7 is screwed onto the constricted section of the air inlet pipe 5. The push rod 12 on the sealing cap 7 pushes the sealing ball 10 away from the opening of the air inlet pipe 5, creating a gap between the outer peripheral wall of the sealing ball 10 and the inner wall of the air inlet pipe 5. At this time, the elastic element 11 is in a compressed state. The bag containing the first reactant 8 is adhered to the second reactant 9. The float is then rolled up and placed inside the life jacket. When drowning and needing to survive, the float is removed, and the sealing cap 7 is screwed off to gradually detach it from the air inlet pipe 5. The push rod 12 loses its thrust on the sealing ball 10, and the sealing ball 10 is pushed towards the constricted section by the elastic force of the deformed elastic element 11. As the bag approaches, the sealing ball 10 seals the constricted section. Simultaneously, the sealing ball 10 pulls the bag through the connecting rope 3, causing the bag to break and spill reactant 8 onto reactant 9, which reacts to generate carbon dioxide, filling the air cavity 4. Carbon dioxide is harmless and non-corrosive to humans. The gas filling causes the belt 1 to unfold and expand. If there is still energy, the sealing cap 7 can be screwed on. If there is no energy, the sealing cap 7 can be left unscrewed, and the gas can be temporarily stored in the belt 1 through the sealing ball 10. If reactant 8 and reactant 9 do not react in the belt 1, air can be blown into the belt 1 to achieve the same effect.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
