Description

Technical Field

[0001] This utility model relates to the field of swimming ring technology, specifically to a swimming ring with an adjustable opening size. Background Technology

[0002] Swimming rings are a common inflatable water toy, mainly used in swimming pools, water parks, and beaches to provide buoyancy assistance and help non-swimmers or those who are not good at swimming maintain buoyancy and balance for water recreation activities. They are usually made of plastic and have advantages such as being inexpensive, having a variety of patterns, and being easy to carry. Swimming rings are different from professional lifesaving equipment such as life rings. They can only be used in shallow, safe environments such as swimming pools under adult supervision and should never be used as a substitute for life rings in deep water areas or natural water bodies to avoid the risk of drowning.

[0003] However, because users' body shapes can easily change, existing swimming rings have fixed sizes and cannot be adjusted. This can easily lead to situations where users grow larger and can no longer wear the swimming ring, rendering it unusable. Therefore, there is an urgent need for a swimming ring with an adjustable opening size. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this application provides a swimming ring with an adjustable opening size. By hooking any two annular sleeves with a protective sleeve, folding or releasing the outer skin of the elastic sleeve, and adjusting the extension length of the elastic sleeve, the opening diameter of the inflatable tube is changed, thereby achieving size adjustment of the swimming ring to meet the needs of people of different body types and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable swimming ring includes: an inflatable tube with a telescopic section, the telescopic section including an elastic sleeve, the elastic sleeve and the inflatable tube being integrally formed and spliced ​​to form the swimming ring; the outer wall of the elastic sleeve is evenly provided with several annular sleeves, two adjacent annular sleeves can be folded to the outer skin of the elastic sleeve between them, and a protective sleeve is provided around the outside of the inflatable tube, the protective sleeve being able to slide and fit outside the telescopic section, pulling any two annular sleeves to displace and fold the outer skin of the elastic sleeve to control the extension or contraction of the inflatable tube.

[0007] Preferably, the protective sleeve is composed of waterproof tape wrapped around the outside of the inflatable tube and then spliced ​​together.

[0008] Preferably, a zipper lock is provided at both ends of the waterproof belt. The zipper lock teeth are fixed to both ends of the waterproof belt, and the protective sleeve is locked by moving the zipper lock head on the zipper teeth.

[0009] Preferably, two connecting pieces are provided at both the upper and lower ends of the annular sleeve in a symmetrical arrangement. The two connecting pieces are sewn to the outer wall of the annular sleeve to pull its displacement.

[0010] Preferably, each of the two connecting pieces has an annular groove at one end that is close to the other, and the inner wall of the protective sleeve has two symmetrically distributed limiting hooks that engage with each other inside the annular groove to pull the connecting piece.

[0011] Preferably, a limiting iron ring is embedded inside the annular through groove, and the connecting piece contacts the limiting iron ring and the limiting hook.

[0012] Preferably, a groove is provided between the lower end face of the connecting piece and the outer wall of the annular sleeve, and the limiting hook engages inside the annular through groove and extends into the groove.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By installing an elastic sleeve on the inflatable tube, when not inflated, the protective sleeve can be slid onto the elastic sleeve. By using the limit hook to hook the connecting piece on any two annular tubes, the outer skin of the elastic sleeve can be folded or released, adjusting the extension length of the elastic sleeve so that the inside of the folded elastic sleeve cannot be inflated. This changes the diameter of the inflatable tube opening, allowing for size adjustment of the swimming ring to meet the needs of people of different body types. Attached Figure Description

[0021] Combination Figures 1-4 As shown in this embodiment, a swimming ring with an adjustable opening size includes: an inflatable tube 1, an inflatable tube 1 with a telescopic part 2, the telescopic part 2 including an elastic sleeve 21, the elastic sleeve 21 and the inflatable tube 1 being integrally formed and spliced ​​to form a swimming ring; by folding or releasing the outer skin of the elastic sleeve 21, the inner part of the folded elastic sleeve 21 cannot be inflated, thereby changing the opening diameter of the inflatable tube 1 integrally formed with it, and realizing the size adjustment of the swimming ring.

[0022] In this embodiment, the outer wall of the elastic sleeve 21 is uniformly provided with a plurality of annular sleeves 22. Two adjacent annular sleeves 22 can be folded to fold the outer skin of the elastic sleeve 21 between them, and a protective sleeve 3 is provided around the outside of the inflatable tube 1. The protective sleeve 3 is slid to the outside of the elastic sleeve 21, and any two annular sleeves 22 are hooked by the limiting hook 31 on the protective sleeve 3. The two annular sleeves 22 are pulled closer to each other, and the annular sleeve 22 and the outer skin of the elastic sleeve 21 between the two annular sleeves 22 are folded to realize the extension or contraction of the elastic sleeve 21.

[0023] In this embodiment, the protective sleeve 3 is composed of a waterproof tape wrapped around the outside of the inflatable tube 1 and then spliced ​​together. The waterproof tape is wrapped around the outside of the inflatable tube 1, and the pull head of the zipper lock 32 is driven to move on the zipper teeth to connect and lock the two ends of the waterproof tape, thus completing the splicing of the protective sleeve 3 and facilitating the subsequent disassembly and assembly of the protective sleeve 3.

[0024] In this embodiment, two connecting pieces 23 are symmetrically distributed at both the upper and lower ends of the annular sleeve 22. The two connecting pieces 23 are sewn to the outer wall of the annular sleeve 22 to pull its displacement. The limiting hook 31 pulls the annular sleeve 22 to move through the connecting pieces 23, adjusts and limits the position of the annular sleeve 22, and prevents the outer skin of the elastic sleeve 21 folded between the two annular sleeves 22 from stretching after inflation, thus ensuring the inflation and use of the swimming ring after the size is adjusted.

[0025] In this embodiment, each of the two connecting pieces 23 has an annular through groove 231 at one end close to the other. The inner wall of the protective sleeve 3 is provided with two symmetrically distributed limiting hooks 31. The limiting hooks 31 are engaged inside the annular through groove 231 to pull the connecting piece 23. By engaging the limiting hooks 31 in the annular through groove 231 to pull the connecting piece 23, the position of the annular sleeve 22 on the connecting piece 23 can be adjusted and limited, thereby realizing the adjustment and limiting of the position of the annular sleeve 22.

[0026] In this embodiment, a limiting iron ring 24 is embedded inside the annular through groove 231, and the connecting piece 23, the limiting iron ring 24, and the limiting hook 31 are in contact. When the swimming ring is used, the limiting iron ring 24 rubs against the limiting hook 31, which prevents the connecting piece 23 from directly contacting the limiting hook 31, and prevents the connecting piece 23 from being damaged due to long-term wear with the limiting hook 31, thus extending its service life.

[0027] In this embodiment, a groove 232 is provided between the lower end face of the connecting piece 23 and the outer wall of the annular sleeve 22. The limiting hook 31 is engaged inside the annular through groove 231 and extends into the groove 232. After the limiting hook 31 is engaged in the annular through groove 231, one end that enters the annular through groove 231 can extend into the groove 232 and pull the connecting piece 23 in the groove 232 to prevent the limiting hook 31 from contacting the annular sleeve 22 and scratching its surface, thereby protecting the annular sleeve 22.

[0028] The working principle of this utility model is as follows: The swimming ring with adjustable opening size proposed in this application is achieved by setting an elastic sleeve 21 on the inflatable tube 1. When not inflated, the protective sleeve 3 is slid onto the elastic sleeve 21. The connecting piece 23 on any two annular tube sleeves 22 is hooked by the limiting hook 31, and the outer skin of the elastic sleeve 21 is folded or released to adjust the extension length of the elastic sleeve 21. This prevents the inside of the folded elastic sleeve 21 from being inflated, thereby changing the opening diameter of the inflatable tube 1 and realizing the size adjustment of the swimming ring to meet the needs of people of different body types.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
