Description

Technical Field

[0001] This utility model relates to the field of life jackets, and in particular to an inflatable self-heating life jacket. Background Technology

[0002] Life jackets are typically vests made of lightweight materials such as cork wrapped in cloth. They are used to provide buoyancy and protection in water, helping the wearer maintain buoyancy and avoid drowning.

[0003] Existing life jackets typically have a carbon fiber heating fabric inside and are equipped with a battery. When a person falls into the water and puts on the life jacket, the battery and the carbon fiber heating fabric are automatically connected through a circuit, and the heating fabric starts working to provide warmth to the person. However, when using life jackets to prevent drowning in water recreation activities, traditional life jackets are usually one-size-fits-all, but the body shapes of the people who need to wear them vary. This results in the life jacket being too big and not fitting snugly to the body of thinner people, while it may not fit larger people. This makes traditional life jackets less suitable and inconvenient to use, and also reduces their protective performance. Utility Model Content

[0004] The technical problem this invention aims to solve is that when using life jackets to prevent drowning in water recreation activities, traditional life jackets are usually one-size-fits-all, but the body shapes of the users vary. This results in the life jacket being too large and not fitting snugly to the body of thinner individuals, while it may not fit larger individuals. This makes traditional life jackets less suitable and inconvenient to use, and also reduces their protective performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an inflatable self-heating life jacket, including a life jacket body, an air bladder fixed to the outer surface of the life jacket body, an inflation tube passing through and connected to one side of the air bladder, a threaded cap threaded to the outer surface of the inflation tube, a limiting device provided on the outer surface of the life jacket body, and an auxiliary fixing device provided on the outer surface of the inflation tube. The limiting device includes a binding strap, a plurality of slots opened on one side of one end of the binding strap, and a square tube block fixedly connected to one side of one end of the binding strap. The other end of the binding strap is inserted into the inner wall of the square tube block. A limiting plate is rotatably connected to one side of the inner wall of the square tube block. One end of the limiting plate is inserted into the inner wall of the slot. Pull blocks are fixedly connected to both sides of one end of the limiting plate. The slot is slidably connected to the inner walls of both sides of the square tube block. Torsion springs are sleeved and connected to the outer surfaces of both sides of one end of the limiting plate. The two ends of the torsion springs are fixedly connected to one side of the limiting plate and one side of the inner wall of the square tube block, respectively. U-shaped blocks are symmetrically fixedly connected to the outer surface of the life jacket body. The binding strap is inserted into the inner wall of the U-shaped blocks.

[0006] The effect achieved by the above-mentioned components is as follows: By setting a limiting device, the existing life jacket body usually has carbon fiber heating cloth inside and is equipped with a battery. Before using the life jacket body, an inflation device is used to inflate the inner wall of the air bladder on the life jacket body through the inflation tube. After it is full, a threaded cap is screwed onto the inflation tube to seal it. When the person in the water puts on the life jacket body, the battery and carbon fiber heating cloth are automatically connected through the circuit, and the heating cloth starts to work, providing warmth to the person in the water. After putting on the life jacket body in water entertainment projects, one side of the binding rope can be tied first, and then one end of the binding strap inserted into the inner wall of the U-shaped block can be inserted into the inner wall of the square tube block. This will first squeeze and push the limiting plate to one end, causing the torsion spring to deform, making it easier to tie. One end of the strap passes through the slot, and when the limiting plate encounters the groove, the torsion spring will drive the limiting plate to reset and lock into the inner wall of the groove. This ensures that the strap can only move to one end within the square tube, tightening and fixing it in place. This allows for adjustment based on the wearer's body size, ensuring the life jacket fits snugly against the wearer's body and preventing it from falling off after falling into the water if not properly fitted. This improves the life jacket's applicability, ease of use, and enhanced protective effect. Similarly, to remove the life jacket, simply manually pull one end of the strap slightly to one side, then manually grasp the pull block and pull it upwards on both sides of the square tube to pull one end of the limiting plate out of the groove. This allows the strap to be easily removed from the inner wall of the square tube for easy removal.

[0007] Preferably, bearings are fixedly connected to both sides of one end of the limiting plate, the outer ring of the bearing is fixedly connected to one side of the inner wall of the square tube block, and the bearing is disposed in the inner wall of the torsion spring.

[0008] The effect achieved by the above components is that by setting torsion springs, the limit plate can be rotated easily while reducing rotational wear between the two sides and the inner wall of the square tube block, thereby improving the service life of the limit plate.

[0009] Preferably, a guide block is fixedly connected to one side of the inner wall of the square tube block, and the guide block is disposed in the inner wall of the end of the square tube block away from the pull block.

[0010] The effect achieved by the above components is that by setting the guide block, the entrance of the square block can be guided, so that after one end of the binding strap is inserted, it is not easy to collide with one end of the torsion spring and the limiting plate, which facilitates operation and use.

[0011] Preferably, a protrusion is fixedly connected to the end of the binding strap away from the square block, and the cross-section of the protrusion is trapezoidal.

[0012] The effect achieved by the above components is that by setting protrusions, the area of ​​one end of the binding strap can be reduced, making it easier to quickly align and snap into the inner wall of the square tube block.

[0013] Preferably, the auxiliary fixing device includes a round hole rod, and the outer surface of the threaded cap is provided with a plurality of rectangular grooves. One end of the round hole rod is fixedly connected to the outer surface of the inflation tube. A locking rod is slidably connected to the inner wall of one end of the round hole rod. A spring is sleeved and connected to the outer surface of one end of the locking rod. The two ends of the spring are fixedly connected to one side of the round hole rod and the locking rod, respectively. One end of the locking rod is inserted into the inner wall of the rectangular groove.

[0014] The effect achieved by the above-mentioned components is as follows: By setting up an auxiliary fixing device, when the threaded cover is put on to seal the airbag after it is fully inflated, the locking rod can be manually pulled to one end in a certain position in the inner wall of the round hole rod, causing the spring to contract. Then, after the threaded cover is tightened, the locking rod is released, and under the reset action of the spring, one end of the locking rod can be driven into the corresponding rectangular groove, which limits and fixes the tightened threaded cover, making it less likely to slip and leak air, improving the sealing effect and avoiding reducing the protective performance of the life jacket body.

[0015] Preferably, one end of the lever is fixedly connected to an operating block, and both sides of the operating block are fixedly connected to several anti-slip strips.

[0016] The effect achieved by the above components is that by setting up the operating block and anti-slip strip, the contact area and friction of one end of the lever can be increased, making it easier to manually grasp and pull one end.

[0017] Preferably, a telescopic protective cover is fixedly connected to one side of the circular hole rod. The telescopic protective cover is sleeved on the outer surface of one end of the spring and the locking rod, and one end of the telescopic protective cover is fixedly connected to one side of the locking rod.

[0018] The effect achieved by the above components is that by setting up a telescopic protective cover, the outer surface of the spring can be protected, preventing external dust and impurities from falling into the middle of the spring and causing it to get stuck, thus facilitating its use.

[0019] Preferably, a reinforcing rod is fixedly connected to both sides of one end of the circular hole rod, and one end of the reinforcing rod is fixedly connected to the outer surface of the inflation tube.

[0020] The effect achieved by the above-mentioned components is that by setting up reinforcing rods, the connection area between the round hole rod and the outer surface of the inflation tube can be increased, making the connection more secure and stable, and less prone to breakage or damage.

[0021] The beneficial effects of this utility model are:

[0022] By setting a limiting device, after putting on the life jacket body in water recreation projects, one side of the binding rope can be tied first. Then, one end of the binding strap, which is inserted into the inner wall of the U-shaped block, is inserted into the inner wall of the square tube block. This causes the limiting plate to rotate to one end, causing the torsion spring to deform, making it easier for one end of the binding strap to pass through. At the same time, when the limiting plate encounters the slot, the torsion spring will drive the limiting plate to reset and lock into the inner wall of the slot, so that the binding strap can only move to one end in the square tube, tightening and fixing it. This allows for adjustment according to the wearer's body size, ensuring that the life jacket body fits snugly against the wearer's body, preventing it from falling off after falling into the water due to improper wearing. This improves the applicability of the life jacket body, making it easier to use and enhancing the protective effect. Attached Figure Description

[0032] Figure 1-5The inflatable self-heating life jacket shown includes a life jacket body 1. An air bladder 4 is fixed to the outer surface of the life jacket body 1. An inflation tube 5 is threaded through and connected to one side of the air bladder 4. A threaded cap 6 is threaded to the outer surface of the inflation tube 5. A limiting device 2 is provided on the outer surface of the life jacket body 1, and an auxiliary fixing device 3 is provided on the outer surface of the inflation tube 5. The limiting device 2 includes a binding strap 21. A plurality of slots 22 are opened on one side of one end of the binding strap 21. A square tube block 23 is fixedly connected to one side of one end of the binding strap 21, and the other end of the binding strap 21 is attached to the inner wall of the square tube block 23. The square tube block 23 is rotatably connected to one side of the inner wall of the square tube block 23. One end of the limit plate 24 is inserted into the inner wall of the slot 22. Pull blocks 25 are fixedly connected to both sides of one end of the limit plate 24. The slot 22 is slidably connected to the inner walls of both sides of the square tube block 23. Torsion springs 26 are sleeved and connected to both sides of the outer surface of one end of the limit plate 24. The two ends of the torsion springs 26 are fixedly connected to one side of the limit plate 24 and one side of the inner wall of the square tube block 23, respectively. U-shaped blocks 27 are symmetrically fixedly connected to the outer surface of the life jacket body 1. The binding straps 21 are inserted into the inner wall of the U-shaped blocks 27. Existing life jacket bodies 1 typically have carbon fiber heating fabric inside and are equipped with batteries. Before using the life jacket body 1, an inflation device is used to inflate the inner wall of the air bladder 4 on the life jacket body 1 through the inflation tube 5. After it is fully inflated, a threaded cap 6 is screwed onto the inflation tube 5 to seal it. When the person in the water puts on the life jacket body 1, the battery and the carbon fiber heating fabric are automatically connected through the circuit, and the heating fabric starts to work, providing warmth to the person in the water. In water recreation activities, after putting on the life jacket body 1, one side of the binding rope can be tied first, and then one end of the binding strap 21, which is inserted into the inner wall of the U-shaped block 27, can be inserted into the inner wall of the square tube block 23. This will cause the limiting plate 24 to rotate to one end, causing the torsion spring 26 to deform, making it easier for one end of the binding strap 21 to pass through. At the same time, the limiting plate 24 rotates to one end, causing the torsion spring 26 to deform, making it easier for one end of the binding strap 21 to pass through. When plate 24 encounters slot 22, torsion spring 26 will drive limiting plate 24 to reset and engage in the inner wall of slot 22, so that the binding strap 21 can only move to one end in the square tube, tightening and fixing it. This allows for adjustment according to the wearer's body size, ensuring that the life jacket body 1 fits snugly against the wearer's body, preventing it from falling off after falling into the water due to improper fit. This improves the applicability of the life jacket body 1, making it easier to use and enhancing its protective effect. Similarly, when it needs to be removed, simply pull one end of binding strap 21 slightly to one end, then manually grasp the pull block 25 and pull it upwards on both sides of the square tube to pull one end of limiting plate 24 out of slot 22. Then, it is easy to remove one end of binding strap 21 from the inner wall of square tube block 23 for easy removal.

[0033] Figure 1-5Bearings 28 are fixedly connected to both sides of one end of the limiting plate 24 shown. The outer ring of the bearing 28 is fixedly connected to one side of the inner wall of the square tube block 23. The bearing 28 is set in the inner wall of the torsion spring 26. By setting the torsion spring 26, the limiting plate 24 can be rotated easily, while reducing the rotational wear between the two sides and the inner wall of the square tube block 23, thereby improving the service life of the limiting plate 24.

[0034] Figure 1-5 A guide block 29 is fixedly connected to one side of the inner wall of the square tube block 23 shown. The guide block 29 is located in the inner wall of the end of the square tube block 23 away from the pull block 25. By setting the guide block 29, the entrance of the square tube block 23 can be guided, so that after one end of the binding strap 21 is inserted, it is less likely to collide with the torsion spring 26 and the end of the limiting plate 24, which facilitates operation. A protrusion 210 is fixedly connected to the end of the binding strap 21 away from the square tube block 23. The cross-section of the protrusion 210 is trapezoidal. By setting the protrusion 210, the area of ​​one end of the binding strap 21 can be reduced, making it easier to quickly align and snap into the inner wall of the square tube block 23.

One end of the round hole rod 32 is fixedly connected to the outer surface of the inflation tube 5. A locking rod 33 is slidably connected to the inner wall of one end of the round hole rod 32. A spring 34 is sleeved on the outer surface of one end of the locking rod 33. The two ends of the spring 34 are fixedly connected to one side of the round hole rod 32 and the locking rod 33, respectively. One end of the locking rod 33 is inserted into the inner wall of the rectangular groove 31. After the airbag 4 is fully inflated, when sealing it with the threaded cap 6, you can first manually pull the lever 33 to one end in the inner wall of the round hole rod 32 to a certain position, causing the spring 34 to contract. Then, after the threaded cap 6 is tightened, release the lever 33 so that, under the reset action of the spring 34, one end of the lever 33 can be driven into the corresponding rectangular groove 31, limiting and fixing the tightened threaded cap 6, making it less likely to slip and leak air, improving the sealing effect, and avoiding reducing the protective performance of the life jacket body 1.

[0036] Figure 1-5An operating block 35 is fixedly connected to one end of the lever 33 shown. Several anti-slip strips 36 are fixedly connected to both sides of the operating block 35. By setting the operating block 35 and anti-slip strips 36, the contact area and friction of one end of the lever 33 can be increased, making it easier to manually grasp and pull one end. A telescopic protective cover 37 is fixedly connected to one side of the round hole rod 32. The telescopic protective cover 37 is sleeved on the outer surface of one end of the spring 34 and the lever 33, and one end of the telescopic protective cover 37 is fixedly connected to one side of the lever 33.

Reinforcing rods 38 are fixedly connected to both sides of one end of the round hole rod 32, and one end of the reinforcing rod 38 is fixedly connected to the outer surface of the inflation tube 5.

[0037] Working principle: Existing life jacket bodies 1 typically have carbon fiber heating fabric inside and are equipped with batteries. Before using the life jacket body 1, an inflation device is used to inflate the inner wall of the air bladder 4 on the life jacket body 1 through the inflation tube 5. After it is fully inflated, a threaded cap 6 is screwed onto the inflation tube 5 to seal it. When the person in the water puts on the life jacket body 1, the battery and the carbon fiber heating fabric are automatically connected through the circuit, and the heating fabric starts to work, providing warmth to the person in the water. In water recreation activities, after putting on the life jacket body 1, one side of the binding rope can be tied first, and then one end of the binding strap 21, which is inserted into the inner wall of the U-shaped block 27, can be inserted into the inner wall of the square tube block 23. This will first squeeze and push the limiting plate 24 to rotate to one end, causing the torsion spring 26 to deform, making it easier for one end of the binding strap 21 to pass through. When the limiting plate 24 encounters the slot 22, the torsion spring 26 will drive the limiting plate 24 to reset and lock into the inner wall of the slot 22, so that the binding strap 21 can only move to one end in the square tube, tightening and fixing it. This allows for adjustment according to the wearer's body size, ensuring that the life jacket body 1 fits snugly against the wearer's body, preventing it from falling off after falling into the water due to improper fit. This improves the applicability of the life jacket body 1, making it easier to use and enhancing the protective effect. Similarly, when it needs to be removed, simply manually pull one end of the binding strap 21 slightly to one end, then manually grasp the pull block 25 and pull it upwards on both sides of the square tube to pull one end of the limiting plate 24 out of the slot 22. Then, it is easy to remove one end of the binding strap 21 from the inner wall of the square tube block 23, making it easy to remove.

[0038] After the airbag 4 is fully inflated, when sealing it with the threaded cap 6, you can first manually pull the lever 33 to one end in the inner wall of the round hole rod 32 to a certain position, causing the spring 34 to contract. Then, after the threaded cap 6 is tightened, release the lever 33 so that, under the reset action of the spring 34, one end of the lever 33 can be driven into the corresponding rectangular groove 31, limiting and fixing the tightened threaded cap 6, making it less likely to slip and leak air, improving the sealing effect, and avoiding reducing the protective performance of the life jacket body 1.
