Detailed ways

In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field belonging to this application. The terms used in the specification of the present application are only for the purpose of describing specific embodiments, and are not used to limit the present application.

As shown in FIG. 1, an easily retractable swimming ring includes an annular ring body 1, the ring body 1 is a closed annular structure, and the ring body 1 is made of a lightweight solid material. Solid materials include EPE, EPS, EVA, NBR, EPP, SBR, TPE, SEBS, EPDM, etc. The advantage of using lightweight solid material to make the ring body is that compared with the hollow inflatable structure, there is no danger of air leakage and buoyancy failure. Moreover, the processing and molding process of the lightweight solid material is relatively simple, and the shape design and The production process has great advantages.

The ring body 1 is provided with a plurality of first notches 11 distributed along the annular direction at its upper end surface, and the ring body 1 is provided with a plurality of second notches 12 distributed along the annular direction at its lower end surface. Specifically, the first incision 11 and the second incision 12 are linearly cut from the upper end surface and the lower end surface of the ring body 1 to the middle side of the ring body by using a sheet-shaped die. The first incision 11 penetrates through the upper end surface, inner side and outer side of the ring body, but the first incision 11 does not penetrate to the lower end surface; the second incision 12 penetrates through the lower end surface, inner side and outer side of the ring body, but The second cutout 12 does not penetrate to the upper end surface. Moreover, as shown in FIG. 5 , the bottom position A of the first incision 11 is lower than the bottom position B of the second incision 12. The function of this setting is that when the first incision and the second incision are opened, the entire ring body can be driven. Circumference increases. In this embodiment, the number of the first notches 11 and the second notches 12 is 6 respectively, and both of them are evenly distributed on the upper end face and the lower end face of the ring body 1 . The positions are staggered with each other in sequence.

In other aspects, the first incision 11 and the second incision 12 can also be made by an integral groove, such as cutting into a triangular or U-shaped cross-section. This also belongs to the protection scope of the present invention.

As shown in FIG. 2 , when the ring body 1 is subjected to the force of being stretched, for example, the two opposite sides of the ring body are respectively held with both hands and pulled to the outside. At this time, due to the force of the ring body, the ring When the first incision and the second incision are in a state of being pulled apart, the opening of the first incision 11 and the second incision 12 will become larger, so that the circumference of the entire ring body will increase, so the inner diameter of the ring body 1 will increase; when the force of the ring body being stretched becomes smaller or removed, the stress acting on the first incision and the second incision of the ring body becomes smaller or disappears. The openings of the first incision and the second incision will become smaller, so that the overall circumference of the ring body becomes smaller, so that the inner diameter of the ring body becomes smaller. 3 and 4, the ring body 1 in Fig. 3 is in a state when the inner diameter is not increased, and the inner diameter is a at this time, and the ring body 1 in Fig. 4 is in a state when the inner diameter is increased, at this time The inner diameter is b, the inner diameter b value is greater than the inner diameter a value, and the size of the inner diameter b value will be different according to the size of the force when the ring body 1 is stretched. The above description also reflects the adaptability of the increase or decrease of the inner diameter and width of the ring body of the swimming ring, which is reflected when the ring body 1 is sheathed on swimmers of different body types.

In some embodiments, as shown in FIG. 6 , the ring body 1 is a non-closed annular structure, and an opening 13 is added at a certain part of the ring body 1 by cutting, and the opening 13 makes the ring body 1 non-closed. The ring body 1 is provided with a connecting device 14 at the opening, and the connecting device straddles both sides of the opening 13. In this embodiment, the connecting device 14 is a Velcro, and the connecting device 14 can make the ring body 1 at the opening 13. The two ends of the ring body 1 are kept aligned and fixed, and the ring body 1 can also be unfolded and flattened by removing the connecting device. In addition, the connecting device 14 can also be a snap connecting belt, a snap connecting belt or a hook connecting belt, etc., which also belong to the protection scope of the present invention.

In some embodiments, as shown in FIG. 7 , in addition to the ring body 1 , the swimming ring also includes a stretchable belt 3 , and the stretchable belt 3 is made of elastically stretchable material, such as a rubber belt, a stretchable braided belt, and the like. An annular groove surrounding the ring body 1 is provided at the outer side of the ring body 1 , and the telescopic belt 3 is sleeved on the annular groove of the ring body 1 . Since the telescopic belt 3 has an elastic expansion and contraction function, the diameter of the telescopic belt 3 will be gradually stretched at the same time as the outer diameter of the ring body 1 changes from small to large during the process from which the ring body 1 is not stretched to being stretched. On the contrary, when the ring body 1 is stretched from being stretched to not being stretched, the diameter of the telescopic belt 3 will be gradually reduced as the outer diameter of the ring body 1 changes from large to small. The function of the telescopic belt 3 is mainly to apply additional inward contraction force to the ring body 1 during the process of expanding or shrinking the ring body 1, so as to enhance the wrapping and compact effect of the ring body when worn.

In some embodiments, as shown in FIG. 8, in addition to the ring body 1, the swimming ring also includes a wrapping layer 2 for wrapping the ring body 1. The figure shows a schematic diagram of the wrapping layer being partially opened. The wrapping layer 2 is made by seaming several pieces of waterproof fabrics, the wrapping layer 2 closely fits the contour of the ring body 1, and the contour of the wrapping layer 2 also conforms to the contours of the first incision 11 and the second incision 12, So that the ring body 1 will not be affected by the wrapping layer 2 when it is stretched.

The above-mentioned embodiments only represent the embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as limiting the scope of the present invention. It should be pointed out that for those of ordinary skill in the art, some modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
