[0028] For the buoyancy-assisting airbag with a cylinder connection device of the present utility model, a wear-resistant ring 10 is provided between the limiting plate 4 and the fixed ring 5, and the outer wall of the wear-resistant ring 10 is in contact with the inner wall of the cylinder 3, which can protect the airbag 1 and prevent the cylinder 3 from wearing the airbag 1 and affecting the service life of the airbag 1.

[0029] For the buoyancy-assisting airbag with a cylinder connection device of the present utility model, a limiting groove is provided on the inner wall of the cylinder 3, a limiting ring 14 is provided at the end of the connecting pipe 6 located inside the cylinder 3, and the connecting pipe 6 is fitted and connected with the limiting groove through the limiting ring 14, which can prevent the connecting pipe 6 and the mounting ring 7 from falling off the cylinder 1 and affecting the convenience of installation.

[0030] A buoyancy aid airbag with a cylinder connection device of the present utility model. A rotating rod 12 is provided on the outer wall of the mounting ring 7. The rotating rod 12 and the mounting ring 7 are of an integral structure. A rubber sleeve is nested on the rotating rod 12, which can facilitate the rotation of the mounting ring 7 driven by the rotating rod 12 and improve the convenience of use.

[0031] A buoyancy aid airbag with a cylinder connection device of the present utility model. A plurality of limiting blocks 13 are arranged around the outer wall of the mounting ring 7 close to the cylinder 3. A guiding groove 15 and a through hole 16 are provided on the cylinder 3. The guiding groove 15 and the through hole 16 are communicated with each other. A limiting mechanism 17 is provided on the cylinder 3. The limiting mechanism 17 includes a clamping block 18, a telescopic rod 20 and a spring 21. The clamping block 18 is fitted and connected in the through hole 16. A dial plate 19 is provided on the outer wall of the clamping block 18. The dial plate 19 penetrates through the guiding groove 15 and extends to the outside of the guiding groove 15. One end of the telescopic rod 20 is fixedly connected to the outer wall of the dial plate 19, and the other end of the telescopic rod 20 is fixedly connected to the inner wall of the guiding groove 15. The spring 21 is nested on the telescopic rod 20, and the spring 21 is pressed between the outer wall of the dial plate 19 and the inner wall of the guiding groove 15, which can limit the mounting ring 7 and prevent the mounting ring 7 from rotating during use, resulting in the detachment of the mounting ring 7 from the fixed ring 5 and affecting the stability of use.

[0032] A buoyancy aid airbag with a cylinder connection device of the present utility model. The positions of the clamping block 18 and the limiting block 13 correspond to each other. Both the clamping block 18 and the limiting block 13 are provided with inclined surfaces. The limiting block 13 is inclined upward, and the clamping block 18 is inclined downward, which can facilitate the extrusion of the clamping block 18 during the clockwise rotation of the mounting ring 7 and is convenient for operation.

[0033] A buoyancy aid airbag with a cylinder connection device of the present utility model. A telescopic plate 22 is provided between the dial plate 19 and the guiding groove 15. The telescopic plate 22 matches the size and structure of the guiding groove 15, making the guiding groove 15 in a closed state and preventing external impurities from entering the inside of the guiding groove 15 and causing damage to the internal components of the guiding groove 15.

[0034] In use, first inflate the airbag 1 through the valve stem 2, then sleeved the cylinder 3 on the airbag 1, and insert the insertion rod 8 on the cylinder 3 into the jack 9 on the limit plate 4, so as to effectively limit the cylinder 3 and prevent it from rotating during use. Then drive the mounting ring 7 to rotate clockwise through the rotating rod 12. During the rotation of the mounting ring 7, it will be threadedly connected to the fixed ring 5 and gradually tightened. During the tightening process of the mounting ring 7, the limit block 13 on the mounting ring 7 will continuously squeeze the latch 18. Since it is tightened clockwise, the latch 18 will not affect the normal rotation of the mounting ring 7 at this time. After the mounting ring 7 is tightened, the latch 18 will be engaged with the limit block 13. By limiting the limit block 13, the phenomenon that the mounting ring 7 rotates counterclockwise during use can be avoided, so as to ensure that the mounting ring 7 will not loosen, thereby effectively ensuring the stability of the cylinder 3 during installation and use. Then, through the lifting ring 11 provided on the cylinder 3, it can be used in cooperation with other equipment or items.

[0035] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
