Description

Technical Field

[0001] The invention relates to the field of lifesaving, and in particular to a lifesaving device. Background Art

[0002] In water activities, rescue and other scenarios, life-saving devices play a vital role in ensuring the safety of people's lives. Some traditional life-saving devices such as life jackets and life-saving bracelets have certain limitations and problems during the inflation process.

[0003] On the one hand, for inflatable life-saving devices, the inflation speed of the airbag is a key factor. In an emergency, every second matters. However, some existing inflatable life-saving devices have the problem of slow inflation, which may cause the drowning person to fail to obtain sufficient buoyancy in time, increasing the risk of drowning. This is mainly due to the internal structure of the device, which makes the gas release and transmission mechanism inefficient and lacks a design structure that can quickly transfer the gas in the cylinder to the airbag.

[0004] On the other hand, the airbags of traditional inflatable life-saving devices are prone to entanglement during storage and inflation. The airbags are usually stored in a folded state. When inflated quickly, due to the impact force of the gas and the folded state of the airbags themselves, they are easily entangled with each other, which in turn affects the normal deployment and use of the airbags, reducing the reliability and effectiveness of the life-saving device.

[0005] In addition, after the life-saving device is used, it is also important to roll up and store the airbag. The airbag rolling process of some existing life-saving devices is cumbersome and requires a lot of time and effort to fold. In addition, improper rolling methods may affect the deployment of the airbag during the next use, such as causing entanglement when inflating again, which brings inconvenience to the reuse of the life-saving device.

[0016] Compared with the related art, the life-saving device provided by the present invention has the following beneficial effects:

[0017] 1. The present invention uses compressed air in a gas cylinder to be transported in an air delivery pipe. When the compressed air is transported to the bucket-shaped cavity, the driving blades simultaneously drive the short shaft to rotate. The side gear on the upper end of the short shaft drives the central gear ring meshed with it to drive the rotating end of the rotary joint to rotate accordingly. The counter joint connected with it drives the airbag placed on the partition net plate to rotate in the opposite direction. The centrifugal force is used to accelerate the airbag to be thrown away during inflation, thereby avoiding the entanglement problem of the folded and stored airbag during sudden inflation, ensuring that the airbag can be deployed normally and quickly, and improving the reliability and safety of the lifesaving device.

[0018] 2. The present invention pinches the top of the airbag and rotates the torsion plate to drive the short shaft to drive the upper side gear to rotate, driving the central gear ring meshed with it to drive the rotating end of the rotary joint and the alignment joint to rotate simultaneously, driving the airbag to rotate forward, and using the rotating torque to twist the airbag into a strip shape, and then twist the plate to the partition net plate on the middle shell, without complicated folding steps, which is not only convenient and fast, but also ensures that the airbag can be quickly and tangled when used next time, thereby improving the operability and reusability of the lifesaving device;

[0019] 3. The present invention uses a pressure plate at one end of the pressure rod to make it slide relative to the inside of the fixed tube. One end of the pressure rod drives the rack rod to slide relative to the limit rail at the same time, driving the sub-gear meshing with it to drive the rotating shaft to rotate, so that the valve body is automatically in an open state, so that the gas in the gas cylinder can quickly flow through the plug-in tube and the gas delivery pipe to the inside of the airbag, so that the airbag can be quickly inflated and deployed, so as to help people who fall into the water float quickly;

[0020] 4. The present invention drives the steel cable to slide relative to the built-in auxiliary rail tube inside the fixed tube through the pressing block. The steel cable is pulled relative to the curved tube at the same time, so that it can drive the back plate to slide relative to the short tube. The back plate then drives the slide rod to drive the wedge-shaped head to retract from the bayonet on the clamping block. At this time, under the action of the torsion spring, the hanging ear on the cover quickly rotates and pops open relative to the engaging seat on the middle shell, so that the airbag stored in the middle shell can be quickly deployed later, further accelerating the deployment speed of the airbag, effectively shortening the life-saving time, and quickly providing buoyancy support for people who fall into the water in an emergency.

[0021] 5. In the present invention, after the gas cylinder is inserted into the gas cavity tube in advance and screwed and fastened, the sealing cap of the gas cylinder mouth is pushed open to form a through connection channel with the plug-in tube. This design makes the preparation work simple and convenient, ensures that the life-saving device can be quickly put into use in an emergency, and provides reliable initial conditions for subsequent gas delivery and airbag inflation.

[0037] It should be noted that: compressed air is delivered to the bucket-shaped cavity, causing the driving blades 48 to rotate simultaneously, driving the short shaft 46 to rotate, and the side gear 47 at the upper end of the short shaft 46 rotates simultaneously, driving the center gear ring 45 meshing with it to rotate, thereby driving the rotating end of the rotary joint 43 to rotate.

[0038] refer to Figure 3 and Figure 7 As shown, a bucket-shaped cavity is provided at one end of the gas delivery pipe 32, and the driving blades 48 are arranged inside the bucket-shaped cavity. One end of the short shaft 46 passes through the wall of the gas delivery pipe 32, and one end of the short shaft 46 is installed and connected with a torsion plate 49.

[0039] It should be noted that the compressed air in the gas cylinder 31 is transported in the gas pipe 32. When it is transported to the bucket-shaped cavity, the driving blades 48 rotate at the same time, driving the short shaft 46 to rotate, thereby providing driving force while deflating.

[0040] refer to Figure 4 and Figure 5As shown, a plug-in tube 6 is fixedly connected to the inner shell wall of the air cavity tube 3, a top head 61 is fixedly connected to the inner wall of the air inlet pipe port of the plug-in tube 6, a valve body 62 is installed and connected in the air inlet pipe of the plug-in tube 6, a rotating shaft 63 is provided on the valve body 62, a sub-gear 64 is fixedly connected to the top of the rotating shaft 63, a fixed tube 65 is fixedly connected to the inner wall of the air cavity tube 3, a pressure rod 66 is slidably connected inside the fixed tube 65, one end of the pressure rod 66 is fixedly connected to a rack rod 67, the rack rod 67 and the sub-gear 64 are meshed with each other, the other end of the pressure rod 66 is fixedly connected to a pressure plate, a limiting rail 68 is fixedly connected to the inner wall of the plug-in tube 6, and the rack rod 67 is slidably connected to the limiting rail 68.

[0041] It should be noted that: the rack rod 67 slides relative to the limit rail 68 at the same time, driving the sub-gear 64 meshing with it to rotate, and the sub-gear 64 drives the rotating shaft 63 to rotate, so that the valve body 62 is automatically in an open state, so that the gas in the gas cylinder 31 can quickly flow through the plug-in tube 6 and the gas pipe 32 to the inside of the airbag 5, so that the airbag 5 can be quickly inflated and deployed, so as to help people who fall into the water to float quickly.

[0042] refer to Figure 5 and Figure 6 As shown, a pressure block 661 is fixedly connected to the pressure rod 66, and the pressure block 661 is arranged inside the fixed tube 65. The inside of the fixed tube 65 is fixedly connected with an internal seat 651. The pressure rod 66 is slidably connected to the internal seat 651. A first spring 662 is sleeved and connected to the pressure rod 66, one end of the first spring 662 is connected to the internal seat 651, and the other end of the first spring 662 is connected to the pressure block 661.

[0043] It should be noted that: pressing the pressure plate at one end of the pressure rod 66 makes it slide relative to the inside of the fixed tube 65, and the pressure block 661 on the pressure rod 66 moves at the same time, causing the first spring 662 to undergo elastic deformation, and one end of the pressure rod 66 can drive the rack rod 67 to slide relative to the limiting rail 68.

[0044] refer to Figure 2 and Figure 8As shown, a cover 7 is provided on the disc shell 4, a hanging ear 71 is provided on the shell wall of the cover 7, an engaging seat 72 is provided on the shell wall of the middle shell 41, the hanging ear 71 is rotatably connected to the engaging seat 72, a small torsion spring is installed and connected between the hanging ear 71 and the engaging seat 72, a clamping block 8 is provided on the shell wall on the other side of the cover 7, the clamping block 8 is provided with a bayonet, a clamping frame 81 is provided on the shell wall of the middle shell 41, the clamping block 8 is aligned with the clamping frame 81, a short cylinder 82 is fixedly connected to the shell wall of the clamping frame 81, a slide rod 83 is slidably connected to the cylinder wall at one end of the short cylinder 82, one end of the slide rod 83 is fixedly connected to the back plate, the other end of the slide rod 83 is fixedly connected to the wedge-shaped head 84, a second spring 85 is sleeved on the slide rod 83, one end of the second spring 85 is connected to the back plate, and the other end of the second spring 85 is connected to the inner wall of the short cylinder 82.

[0045] It should be noted that: when the card frame 81 rotates to abut against the inclined surface of the wedge-shaped head 84, the wedge-shaped head 84 drives the slide bar 83 to slide relative to the short tube 82, and the second spring 85 is elastically deformed. When the bayonet on the card frame 81 rotates to overlap with the wedge-shaped head 84, the second spring 85 restores its elastic deformation, so that the slide bar 83 drives the wedge-shaped head 84 to retract from the bayonet on the card block 8, and automatic locking can be achieved, so that after the airbag 5 is installed, it can be automatically locked by the cover 7 and the middle shell 41.

[0046] The back plate slides relative to the short cylinder 82, and the back plate drives the slide bar 83 to slide accordingly, and the second spring 85 undergoes elastic deformation, so that the slide bar 83 drives the wedge-shaped head 84 to retract and leave the slot on the block 8. At this time, under the action of the torsion spring, the hanging ear 71 on the cover 7 quickly rotates and pops open relative to the fitting seat 72 on the middle shell 41, so that the airbag 5 stored inside the middle shell 41 can be quickly deployed later, further accelerating the deployment speed of the airbag 5.

[0047] refer to Figure 6 and Figure 8 As shown, a curved tube 9 is fixedly connected to the tube wall of the short tube 82, and the other end of the curved tube 9 is connected to the tube wall of the fixed tube 65. A steel cable 91 is provided inside the curved tube 9, one end of the steel cable 91 is connected to the back plate, and the other end of the steel cable 91 is connected to the pressing block 661. A built-in auxiliary rail tube 92 is provided inside the fixed tube 65, and the steel cable 91 is slidably connected to the built-in auxiliary rail tube 92.

[0048] It should be noted that the built-in auxiliary rail tube 92 and the curved tube 9 are used in combination so that the steel cable 91 can slide stably for traction;

[0049] The movement of the pressing block 661 drives the steel cable 91 to slide relative to the built-in auxiliary rail tube 92 inside the fixed tube 65. The steel cable 91 is pulled relative to the curved tube 9 at the same time, so that it can drive the back plate to slide relative to the short tube 82, so that pressing the pressure rod 66 can drive the sliding rod 83 to move simultaneously.

[0050] The working principle of a life-saving device provided by the present invention is as follows: the gas cylinder 31 is inserted into the interior of the gas cavity tube 3 in advance and screwed into a tightened state, so that the top head 61 at the air inlet port of the plug-in tube 6 pushes open the sealing cap at the bottle mouth of the gas cylinder 31, so that a through connecting channel is formed between the gas cylinder 31 and the plug-in tube 6, which is convenient for subsequent life-saving use.

[0051] When encountering an emergency, the pressure plate at one end of the pressure rod 66 is pressed to make it slide relative to the inside of the fixed tube 65. The pressure block 661 on the pressure rod 66 moves at the same time, causing the first spring 662 to undergo elastic deformation. One end of the pressure rod 66 drives the rack rod 67 to slide relative to the limit rail 68 at the same time, driving the sub-gear 64 meshing with it to rotate. The sub-gear 64 drives the rotating shaft 63 to rotate, so that the valve body 62 is automatically in an open state, so that the gas in the gas cylinder 31 can quickly flow through the plug-in tube 6 and the gas supply pipe 32 to the inside of the airbag 5, so that the airbag 5 can be quickly inflated and deployed to help people who fall into the water float quickly.

[0052] The movement of the pressure block 661 drives the steel cable 91 to slide relative to the built-in auxiliary rail tube 92 inside the fixed tube 65. The steel cable 91 is pulled relative to the curved tube 9 at the same time, so that it can drive the back plate to slide relative to the short tube 82, and the back plate then drives the slide bar 83 to slide. The second spring 85 undergoes elastic deformation, so that the slide bar 83 drives the wedge-shaped head 84 to retract and leave the bayonet on the block 8. At this time, under the action of the torsion spring, the ear 71 on the cover 7 quickly rotates and bounces open relative to the mating seat 72 on the middle shell 41, so that the airbag 5 stored inside the middle shell 41 can be quickly deployed subsequently, further accelerating the deployment speed of the airbag 5, so as to effectively shorten the subsequent life-saving time.

[0053] The compressed air in the gas cylinder 31 is transported in the gas pipe 32. When it is transported to the bucket-shaped cavity, the driving blades 48 rotate at the same time, driving the short shaft 46 to rotate. The side gear 47 on the upper end of the short shaft 46 rotates at the same time, driving the central gear ring 45 meshing with it to rotate, so that it drives the rotating end of the rotary joint 43 to rotate accordingly. The alignment joint 44 connected to it drives the airbag 5 placed on the partition mesh plate 441 to rotate in the opposite direction, and the centrifugal force is used to accelerate the airbag 5 to be thrown away, which can effectively prevent the folded and stored airbag 5 from being entangled when suddenly inflated, and prevent it from being entangled when quickly inflated, ensuring that it can be deployed normally and quickly, which is very safe and efficient.

[0054] After use, when the airbag 5 is rolled up and stored, pinch the top of the airbag 5 and rotate the torsion disk 49 at the lower end of the short shaft 46 at the same time, so that the short shaft 46 drives the side gear 47 at the upper end to rotate, driving the central gear ring 45 meshing with it to rotate, so that it drives the rotating end of the rotating joint 43 and the alignment joint 44 to rotate at the same time, driving the airbag 5 to rotate in the forward direction, and using the rotating torque to twist the airbag 5 into a strip shape, and then twist the disk to the partition mesh disk 441 on the middle shell 41, so as to realize quick and convenient rolling up of the airbag 5 without the need for cumbersome folding steps, while also ensuring that it can be quickly and tangle-free unfolded when used next time.
