Description

Technical Field

[0001] This application relates to the technical field of sporting goods, and in particular to a buoyancy-adjustable life jacket. Background Technology

[0002] Buoyancy vests are essential equipment for children's water safety. Traditional children's floatation vests generally adopt a fixed buoyancy design, usually consisting of non-adjustable foam filling material or a single air chamber. Although this structure can provide basic buoyancy, it cannot be adaptively adjusted according to different children's weight, swimming skill level, or water environment, which may lead to problems of insufficient or excessive buoyancy in actual use.

[0003] Currently available adjustable buoyancy products include inflatable floaties or detachable floats. However, inflatable structures pose a risk of air leakage and are inconvenient to adjust, while detachable floats are cumbersome to disassemble and prone to parts loss. Furthermore, as children's swimming abilities improve, parents often need to purchase multiple floaties with different buoyancy levels, which not only increases the financial burden but also wastes resources. Utility Model Content

[0004] The purpose of this application is to overcome the shortcomings of the prior art and provide a buoyancy-adjustable life jacket that can adjust the buoyancy according to actual needs.

[0005] The objective of this application is achieved through the following technical solution:

[0025] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0026] Please see Figures 1 to 2 This is an embodiment of the adjustable buoyancy life jacket 10, which includes a front chest buoyancy assembly 100, a neck connecting ring 200, and a back buoyancy strap 300. The front chest buoyancy assembly 100 includes a left buoyancy plate 110 and a right buoyancy plate 120, which are connected by a detachable connector 130. The two ends of the opening of the neck connecting ring 200 are fixedly connected to the upper parts of the left buoyancy plate 110 and the right buoyancy plate 120, respectively. The two ends of the back buoyancy strap 300 are fixedly connected to the left buoyancy plate 110 and the right buoyancy plate 120, respectively. The back buoyancy strap 300 has a placement cavity (not shown) for placing buoyancy blocks (not shown), and the back buoyancy strap 300 has a replacement port (not shown) communicating with the placement cavity for replacing or adding / removing buoyancy blocks.

[0027] Specifically, when wearing the adjustable buoyancy life jacket 10, first adjust the buoyancy to a suitable level by adjusting the size or number of buoyancy blocks in the back buoyancy strap 300 according to the user's body shape and buoyancy requirements. After gently slipping the neck connecting ring 200 around the neck, place the left buoyancy plate 110 and right buoyancy plate 120 on the front of the body and secure them reliably using the detachable connector 130 to ensure that the adjustable buoyancy life jacket 10 remains firmly and snugly against the body. The double securing of the neck and chest buoyancy components 100 allows for quick donning and doffing as well as safe fixation.

[0028] In this embodiment, the adjustable buoyancy life jacket 10 allows for adjustment of the buoyancy blocks through a replacement port on the back buoyancy strap 300, thus enabling the buoyancy adjustment function of the life jacket 10 to adapt to different buoyancy requirements. Furthermore, the neck connecting ring 200, the front chest buoyancy component 100, and the back buoyancy strap 300 are fixedly connected, avoiding the problems of cumbersome disassembly and easy loss of separate floats. The double fixation of the neck connecting ring 200 and the front chest buoyancy component 100 enables quick donning and doffing as well as safe securing, ensuring stability during wear.

[0029] In another embodiment, the replacement opening is a zippered or snap-on window, which facilitates closure after the buoyancy block is replaced.

[0030] like Figure 1 As shown, in one embodiment, the neck connecting ring 200 and the left buoyancy plate 110 and right buoyancy plate 120 are integrally formed. It is understood that this integral design eliminates the need for connecting structures, resulting in a more uniform and stable buoyancy distribution, improving the safety and durability of the adjustable buoyancy life jacket 10, and enhancing the overall safety and durability of the product.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the two ends of the back buoyancy strap 300 are sewn to the lower parts of the left buoyancy plate 110 and the right buoyancy plate 120, respectively. It can be understood that the back buoyancy strap 300 is separated from the front chest buoyancy assembly 100 by a sewn connection structure, which restricts the displacement of the buoyancy blocks within the placement cavity during use, maintaining a stable buoyancy distribution. At the same time, the sewn connection structure ensures both connection stability and improved wearing comfort.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, there are multiple placement cavities. Specifically, in this embodiment, there are six placement cavities, providing balanced buoyancy support while ensuring flexibility of movement. The modular structure allows the buoyancy scheme to be freely adjusted according to the user's body size and buoyancy requirements.

[0033] like Figure 2 As shown, in one embodiment, a shielding portion 310 is provided on the side of the back buoyancy strap 300 facing the front chest buoyancy assembly 100. One end of the shielding portion 310 is connected to the side of the back buoyancy strap 300 away from the front chest buoyancy assembly 100, and the shielding portion 310 is used to shield the replacement port. Specifically, in this embodiment, the replacement port is located at the bottom of the back buoyancy strap 300. The shielding portion 310 covers the replacement port and extends upward along the back buoyancy strap 300, forming an anti-detachment structure through the extension of the shielding portion 310 to prevent the buoyancy block from falling out during use. At the same time, using the shielding portion 310 to replace the traditional connector simplifies the assembly process.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the height of both ends of the back buoyancy band 300 is lower than the height of the middle section. It is understood that by lowering the height of the ends of the back buoyancy band 300 relative to the user's armpits, friction between the back buoyancy band 300 and the armpits or arms is avoided during use, improving wearing comfort and reducing the feeling of restriction. Furthermore, the middle section is higher than the ends to ensure sufficient buoyancy support for the back.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the two ends and the middle of the back buoyancy band 300 are smoothly connected by an arc-shaped transition section. The arc-shaped transition between the two ends and the middle of the back buoyancy band 300 avoids sharp edges at the connection point, thus preventing scratches and further improving wearing comfort.

[0036] like Figure 1 As shown, in one embodiment, the front chest buoyancy assembly 100 further includes a first connecting strap 140 and a second connecting strap 150. One end of the first connecting strap 140 is fixedly disposed on the side of the left buoyancy plate 110 facing away from the back buoyancy belt 300, and one end of the second connecting strap 150 is fixedly disposed on the side of the right buoyancy plate 120 facing away from the back buoyancy belt 300. The detachable connector 130 includes a male buckle 131 and a female buckle 132 that are interlocked. The male buckle 131 is disposed at the other end of the first connecting strap 140, and the female buckle 132 is disposed at the other end of the second connecting strap 150. The male buckle 131 and the female buckle 132 are fastened together. It can be understood that placing the first connecting strap 140, the second connecting strap 150, and the detachable connector 130 on the front surface of the front chest buoyancy assembly 100 avoids side friction and improves wearing comfort. At the same time, the single-point fastening at the front chest facilitates quick wearing.

[0037] Compared with the prior art, this application has at least the following advantages:

[0038] The aforementioned adjustable buoyancy life jacket features a replacement port on the back buoyancy strap, allowing for adjustment of the buoyancy blocks and thus enabling buoyancy adjustment to meet different buoyancy requirements. Furthermore, the neck connecting ring, chest buoyancy assembly, and back buoyancy strap are securely connected, avoiding the problems of cumbersome disassembly and easy loss of separate floats found in split-type life jackets.

[0039] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
