[0023] The present invention is further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention made by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0024] like Figures 1 to 7 As shown, the utility model provides a safety airbag that can provide stable buoyancy underwater, including an airbag mechanism, an air source device 2 and a fixing assembly 1. The airbag mechanism includes a bladder body 6, a protective cover 4 covering the bladder body 6, and a packaging device 3 for fixing and constraining the bladder body. The fixing assembly 1 includes a base 11 and two fixing ring brackets 12 arranged on the base 11. Two protective cover drawstrings 5 ​​are provided on the protective cover 4. The protective cover drawstrings 5 ​​are sleeved on the protective cover 4. Two hanging rings 51 are provided on the protective cover drawstrings 5. The base 11 is provided with a lug 13 matching the hanging ring 51. The packaging device 3 is connected to the protective cover 4. It is fixed to the base 11 by bolt connection, the sac 6 and the protective cover 4 are located in the packaging device 3, the hanging ring 51 extends out of the packaging device 3 and cooperates with the lug 13, the air source device 2 is fixed to the base 11 by two fixing ring brackets 12, three safety air pressure valves 61, an air charging and discharging valve 62, and an air inlet interface 63 are provided on the sac 6, four mounting seats 64 are provided on the sac 6, the three safety air pressure valves 61 and the air charging and discharging valve 62 are respectively installed on the sac 6 through the four mounting seats 64, and the air source device 2 provides air source to the sac 6 on the packaging device 3 through the air inlet interface 63.

[0025] like Figure 8 and Figure 9 As shown, the gas source device 2 includes a gas cylinder 21, an integrated valve 22, and an outlet pipe 23. The integrated valve 22 is disposed at the outlet end of the gas cylinder 21. One end of the outlet pipe 23 is connected to the integrated valve 22, and the other end is connected to the air inlet interface 63. The integrated valve 22 includes a vent pipe 24, a stop valve 25, a pressure gauge 27, a solenoid valve 26, a safety valve 28, and an air charging connector 29. The stop valve 25 is used to open and close the vent pipe 24; the pressure gauge 27 is used to measure and display the air pressure in the vent pipe 24; the solenoid valve 26 is used to control the opening and closing of gas delivery; the safety valve 28 is used to shut off and stop the gas supply according to the air pressure to ensure safe gas supply; and the air charging connector 29 is used to inflate the gas cylinder 21.

[0026] like Figure 10As shown, the operation mode of the integrated valve 22 is: open the stop valve 25 before use. When in use, the solenoid valve 26 receives the system electrical signal and opens the valve. High-pressure air enters the bag 6 from the gas cylinder 21 through the ventilation pipe 24. During this process, the pressure gauge 27 monitors the air pressure during the inflation process. Once the safety pressure is exceeded, the safety valve 28 will be closed in time to stop further inflation to ensure that the airbag 6 will not rupture during the inflation process.

[0027] During the inflation process, the airbag 6 becomes larger and larger, and the protective cover 4 also becomes larger. The protective cover 4 and the airbag 6 break through the constraints of the packaging device 3 and finally Figure 1 and Figure 3 The status shown becomes Figure 2 and Figure 5 During the inflation process of the airbag 6, the airbag 6 is exhausted synchronously through the three safety air pressure valves 61, which not only controls the air pressure in the airbag 6 but also prevents the bag 6 from rupturing due to over-rapid inflation.

[0028] This can ensure that the bladder 6 can be stably inflated without any accidents. The bladder 6 can provide stable buoyancy, and because the bladder 6 is effectively fixed by the protective cover drawstring 5 and the packaging device 3 is effectively fixed by the base 11 during the inflation and ascent process, the structural strength of the overall device is relatively high. Under the action of the buoyancy of the bladder 6, the overall device can rise at a stable speed without positional deviation, etc., ensuring that the overall device can accurately float to the water surface.
