[0039] See also Figure 5 and Figure 7The extrusion assembly includes two first fixing members 114, which are respectively fixed to the left and right sides of the upper part of the backpack 1, and the second springs 115 are fixed to the first fixing members 114. The lower side of the second springs 115 is fixed with a first limiting member 113, and the first limiting member 113 is squeezed and matched with the inclined surface on the corresponding latch 15. The lower part of the first limiting member 113 is provided with an inclined surface, and the first limiting member 113 is squeezed and matched with the corresponding gas cylinder box 12.

[0040] See also Figure 4-Figure 7 The inflation component includes two air valves 19, which are symmetrically fixed and connected to the left and right sides of the hose 18. A return torsion spring is arranged in the air valve 19. A fixing plate 110 is fixed to the left and right sides of the upper part of the backpack 1. The fixing plate 110 and the corresponding air valve 19 are rotatably connected. The sides of the fixing plates 110 that are close to each other are rotatably connected to pulleys 111. The sides of the air valves 19 that are away from each other are clamped and connected to the gas tank 17. A pressure switch is arranged on the side of the gas tank 17 close to the gas valve 19. The gas tank 17 and the corresponding gas cylinder box 12 are clamped and matched. A draw rope 14 is fixed to the air valve 19, and the draw rope 14 passes around the corresponding pulley 111 and passes through the corresponding shoulder strap 11.

[0041] See also Figure 1 , Figure 2 and Figure 6 , and also includes two pull rings 13, which are respectively fixed on the side of different pull ropes 14 away from the air valve 19.

[0042] See also Figure 5 and Figure 7 , and also includes four first springs 112, each two first springs 112 form a group, and each group of first springs 112 is respectively fixed between different gas cylinder boxes 12 and fixing plates 110.

[0043] The present invention can be used when people are mountaineering or traveling in the wild. When people fall into water in the wild, they can manually pull the pull ring 13 downwards, and the pull ring 13 drives the pull rope 14 to be pulled downwards, and the pull rope 14 drives the air valve 19 to rotate counterclockwise, so that the air valve 19 is opened, and the high-pressure gas in the gas tank 17 enters the air bag 16 through the hose 18, so that the air bag 16 begins to expand, and the air bag 16 expands upward and becomes larger, so that the buoyancy of the air bag 16 is increased. When the air bag 16 is fully expanded, people release the pull ring 13. Because the air valve 19 is provided with a torsion spring, when the pull rope 14 no longer pulls the air valve 19 downwards, the air valve 19 will rotate clockwise to reset, and the air valve 19 will be closed, so as to prevent the gas in the air bag 16 from leaking. The body re-enters the gas tank 17, and the expanded air bag 16 can drive people to float up to the surface, thereby reducing the possibility of people drowning and buying more rescue time for the drowning people. After people are rescued to the shore, because the gas in the gas tank 17 is discharged, people need to re-inflate the gas tank 17. When people need to take out the gas tank 17 to inflate, people first push the left and right latches 15 to the side close to each other, and the latches 15 squeeze the corresponding first limiting members 113, so that the first limiting members 113 move upward, the second springs 115 are compressed, the first limiting members 113 no longer block the gas cylinder box 12, and the first springs 112 are reset from the compressed state, and the first springs 112 drive the gas cylinder box 12 to move to the side away from each other. , so that the gas cylinder box 12 drives the gas cylinder 17 to move toward the side away from each other, and the gas cylinder 17 is separated from the gas valve 19. Because the side of the gas cylinder 17 close to the gas valve 19 is provided with a pressure switch, when the gas cylinder 17 and the gas valve 19 are engaged with each other, the switches on the gas cylinder 17 will be turned on. When the gas cylinder 17 is separated from the gas valve 19, the pressure switch is no longer squeezed, and the switches on the gas cylinder 17 will be closed. When the gas cylinder 17 is ejected, people no longer press the latch 15, and the second spring 115 is reset to drive the first limit member 113 to move downward. The first limit member 113 squeezes the latch 15 downward, so that the latch 15 is squeezed to move toward the side away from each other. People can take out the gas cylinder 17 and then inflate the gas cylinder 17. After the gas is inflated, people The gas cylinder 17 is re-engaged with the gas cylinder box 12, and then people push the gas cylinder box 12 into the backpack 1 again, the first spring 112 is compressed, the gas cylinder box 12 squeezes the first limiter 113, so that the first limiter 113 is squeezed and moved upward, and the second spring 115 is compressed. When the gas cylinder box 12 is separated from the first limiter 113, the second spring 115 is reset to drive the first limiter 113 to move downward and reset, and the first limiter 113 blocks the gas cylinder box 12 again, and the gas cylinder 17 and the gas valve 19 are re-engaged. The above operation pulls the gas valve 19 downward through the pull rope 14 to open the gas valve 19, and the high-pressure gas in the gas cylinder 17 enters the airbag 16 through the hose 18, so that the airbag 16 expands.The inflated airbag 16 can drive people to float up to the surface of the water, thereby reducing the possibility of drowning, buying more rescue time for drowning people, and avoiding the airbag 16 being set between the backpack 1 and the back of people, thereby affecting the use of the airbag 16.

[0044] Example 2: Based on Example 1, please refer to Figure 8-Figure 10 , and also includes a balancing mechanism that can intuitively reflect the balanced state of the center of gravity of the items in the backpack 1, the balancing mechanism includes a balancing board 2, the balancing board 2 is rotatably connected to the lower part of the backpack 1, a pointer 22 is fixed to the front of the balancing board 2, the pointer 22 is rotatably connected to the backpack 1, and the left and right sides of the lower part of the backpack 1 are slidably connected to the second limiting members 21, the rear parts of the second limiting members 21 are squeezed and matched with the balance board 2, and the second limiting members 21 are grooved on the sides close to each other, and a limiting component that can limit the second limiting member 21 is connected to the backpack 1.

[0045] See also Fig.10 The limiting component includes two extrusion blocks 23, which are symmetrically slidably connected to the left and right sides of the lower part of the backpack 1. The sides of the extrusion blocks 23 that are away from each other are provided with inclined surfaces. The extrusion blocks 23 are snap-fitted with the grooves on the corresponding second limiting members 21. The extrusion blocks 23 are extruded and fitted with the corresponding second limiting members 21. A third spring 24 is fixedly connected between the extrusion blocks 23 and the backpack 1.

[0046] Because people will put a lot of supplies in the backpack 1 when traveling outdoors in case of emergency, and when there are a lot of things in the backpack 1, it is easy to cause the backpack 1 to be unbalanced. When the center of gravity of the backpack 1 is unbalanced, people will suffer from muscle soreness on one side of the shoulder after carrying the backpack 1 for a long time. Therefore, a balancing mechanism is provided that can intuitively reflect the balanced state of the center of gravity of the items in the backpack 1. The following is its working principle: first, people pull the second limiting members 21 forward, and the second limiting members 21 squeeze the inclined surface on the rear side of the corresponding squeezing block 23 during the forward movement, so that the squeezing blocks 23 move toward the side close to each other, and the third spring 2 4 are compressed. When the second limiting member 21 and the extrusion block 23 are separated, people no longer pull the second limiting member 21 forward, and the third spring 24 is reset. The third spring 24 drives the extrusion block 23 to move to the side away from each other. At the same time, the second limiting member 21 no longer restricts the balance board 2, so that the balance board 2 can flip up and down. Then people put items into the backpack 1. When the center of gravity of the objects in the backpack 1 is unbalanced, the balance board 2 will rotate, and the balance board 2 drives the pointer 22 to rotate. The deflection of the pointer 22 can show the direction in which the center of gravity of the objects in the backpack 1 is biased. After knowing this, people can adjust the objects in the backpack 1. The backpack 1 is arranged until the center of gravity of the objects in the backpack 1 is approximately in the middle position. Then, the second limiting member 21 is pushed backward again, and the second limiting member 21 squeezes the corresponding squeezing block 23, so that the squeezing blocks 23 move toward the side close to each other, the third spring 24 is compressed, and the second limiting member 21 supports the balance board 2 again. When the grooves on the second limiting member 21 are aligned with the corresponding squeezing blocks 23, the second limiting member 21 no longer squeezes the squeezing blocks 23, and the third spring 24 is reset. The third spring 24 drives the squeezing blocks 23 to move toward the side away from each other, and the squeezing blocks 23 are aligned with the corresponding The groove on the corresponding second limit piece 21 is engaged with the squeeze block 23, and the second limit piece 21 will not slide out of the backpack 1 under the limiting effect of the squeeze block 23 on the second limit piece 21, so that the second limit piece 21 can support the left and right sides of the balance board 2 respectively, so that the items in the backpack 1 can always keep the center of gravity balanced. The above operation is carried out by setting the balance board 2 and the pointer 22, so that when people put items into the backpack 1, they can clearly understand whether the center of gravity of the objects in the backpack 1 is balanced, and make adjustments accordingly. Therefore, people no longer need to carry the backpack 1 on their backs to feel that the center of gravity is very balanced, which saves time and effort.

[0047] See also Figure 11-13, and also includes a tightening mechanism that can prevent the backpack 1 from being separated from people due to movement when drowning. The tightening mechanism includes four support plates 34, each two support plates 34 form a group, and each group of support plates 34 is symmetrically fixed on the left and right sides of the lower part of the backpack 1. The left and right sides of the backpack 1 are rotatably connected with adjustment rods 3, and the adjustment rods 3 are rotatably connected to the corresponding support plates 34. A ratchet 32 ​​is fixed on the side where the adjustment rods 3 are close to each other, and a roller 31 is fixed on the side where the ratchet 32 ​​is close to each other. The roller 31 is fixedly connected to the slidable end of the corresponding shoulder strap 11, and the roller 31 is rotatably connected to the corresponding support plate 34. A first torsion spring 33 is fixed between the roller 31 and the support plate 34, and a blocking component that can block the rotation of the ratchet 32 ​​is connected to the pull rope 14.

[0048] See also Fig.13 The blocking assembly includes a moving frame 35, which is fixed between the side of the pull rope 14 close to the roller 31. The lower sides of the left and right sides of the moving frame 35 are rotatably connected with pawls 36, the pawls 36 are rotatably connected to the corresponding rollers 31, and the pawls 36 are squeezed and fitted with the corresponding ratchet wheels 32.

[0049] Because if people fall into the water, they will struggle and float in the water, which may cause the backpack 1 to separate from the people, making them lose the buoyancy of the airbag 16. Therefore, a tightening mechanism is provided to prevent the backpack 1 from separating from the people in the water. The following is its working principle: when people fall into the water, they manually pull the pull ring 13 downward, thereby driving the pull rope 14 to be pulled downward, and the pull rope 14 drives the movable frame 35 to move upward, and the movable frame 35 drives the pawl 36 to move, so that the pawl 36 rotates counterclockwise, and the pawl 36 no longer restricts the ratchet 32, so that the first torsion spring 33 is reset from the twisted state, and the first torsion spring 33 is reset to drive the roller 31 to rotate counterclockwise, and the roller 31 drives the ratchet 32 ​​and then drives the adjusting rod 3 to rotate counterclockwise, and the roller 31 rotates counterclockwise, so that the roller 31 reels the corresponding shoulder strap 11, and the shoulder strap 11 is tightened, so that the shoulder strap 11 drives the backpack 1 to be closely attached to the people, thereby preventing the backpack 1 from separating from the people, avoiding To prevent people from drowning due to the loss of the buoyancy of the airbag 16, people then release the pull ring 13. When people are rescued to the shore, they can pull the pull ring 13 again, so that the pull rope 14 drives the moving frame 35 to move upward, and then people turn the adjusting rod 3 clockwise, the adjusting rod 3 drives the ratchet 32 ​​and then drives the roller 31 to rotate clockwise, the first torsion spring 33 is twisted, and then people release the pull rope 14, the pull rope 14 drives the moving frame 35 and then drives the ratchet 36 to rotate clockwise. The pawl 36 is reset so that it squeezes and restricts the ratchet 32 ​​again. The above operation drives the movable frame 35 through the pull rope 14 and then drives the pawl 36 to rotate counterclockwise, so that the pawl 36 no longer blocks the ratchet 32, and then the roller 31 is driven by the first torsion spring 33 to rotate counterclockwise. The roller 31 reels the shoulder strap 11, so that the shoulder strap 11 drives the backpack 1 to fit closely with the people, thereby preventing the backpack 1 from separating from the people and preventing people from drowning due to the loss of the buoyancy of the airbag 16.

[0050] See also Figure 14-16 , and also includes a protection mechanism that can protect the airbag 16 to prevent the airbag 16 from being scratched by external objects during outdoor movement. The protection mechanism includes two third fixing members 41, and the third fixing members 41 are fixed to the upper side of the backpack 1. A protection plate 4 is rotatably connected between the third fixing members 41, and a second torsion spring 42 is fixed between the protection plate 4 and the third fixing member 41 on the left.

[0051] Because there are many trees in the wild, people will encounter many trees when walking in the wild, so the airbag 16 may be scratched by branches, thus affecting its use. Therefore, a protection mechanism that can protect the airbag 16 is provided. The following is its working principle: In order to protect the airbag 16, a protection plate 4 is provided. Before the airbag 16 is inflated, the protection plate 4 can separate the airbag 16 from the outside world, thereby protecting the airbag 16. When the airbag 16 is inflated, the airbag 16 expands upward and squeezes the protection plate 4, causing the protection plate 4 to rotate counterclockwise, and the second torsion spring 42 is twisted. After the airbag 16 is deflated and contracted, the second torsion spring 42 is reset to drive the protection plate 4 to rotate clockwise and reset. The above operation is performed by setting a protection plate 4, and the protection plate 4 separates the airbag 16 from the outside world, thereby preventing external objects from causing damage to the airbag 16, thereby affecting its use.

[0052] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims.
