[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0025] Example 1
[0026] See Figures 1-3 This embodiment discloses a diving fin, including a fin cover 1 and a webbed plate 2; the fin cover 1 is open at one end and connected to the webbed plate 2 at the other end. In this embodiment, the upper surface and / or lower surface of the webbed plate 2 is provided with ribs, the ribs extend along the length direction of the webbed plate 2, and a portion of the ribs is connected to the surface of the fin cover 1.
[0027] Furthermore, to enhance the rebound performance of the fins, this embodiment provides two ribs on both the upper and lower surfaces of the fin plate 2, with the ribs on the upper surface corresponding one-to-one with those on the lower surface. Specifically, the rib on the upper surface of the fin plate 2 is the upper rib 3; a portion of the upper rib 3 protrudes onto the surface of the shoe cover 1, and the height of the protrusion of the upper rib 3 on the fin plate 2 gradually decreases from the end closer to the shoe cover 1 to the end farther away from the shoe cover 1. The rib on the lower surface of the fin plate 2 is the lower rib 8; a portion of the lower rib 8 protrudes onto the surface of the shoe cover 1, and the height of the lower rib 8 on the fin plate 2 gradually decreases from the end closer to the shoe cover 1 to the end farther away from the shoe cover 1. In this embodiment, the two lower ribs 8 on the lower surface of the fin plate 2 are arranged opposite each other and have a certain height, especially forming a groove 9 at the junction of the fin plate 2 and the shoe cover 1, which is beneficial for guiding water flow and further improving propulsion efficiency during diving or swimming.
[0028] Furthermore, auxiliary ribs 4 are provided on the upper and lower surfaces of the web plate 2, and the auxiliary ribs 4 are located on the outer side of the ribs; the auxiliary ribs 4 on the upper and lower surfaces of the web plate 2 correspond to each other. By setting the auxiliary ribs 4, the resilience performance of the web plate 2 is further improved, making the web plate 2 more resilient after being bent under force.
[0029] Furthermore, the two side edges of the fin 2 are bent towards the upper surface. Reinforcing ribs 7 are provided at the bent points on both sides of the lower surface of the fin 2. In this embodiment, the bent side edges of the fin 2 allow the upper surface to concentrate water as much as possible on the force-bearing surface of the fin 2 when the diver uses it for propulsion, thus enabling the fin 2 to make fuller contact with the water and achieve efficient propulsion. The reinforcing ribs 7 not only improve the strength of the bent area but also provide good resilience at that location, ensuring the overall resilience of the fin 2.
[0030] Furthermore, the lower surface of the shoe cover 1 is provided with a first anti-slip part 10 and a second anti-slip part; the first anti-slip part 10 is located in the middle of the lower surface of the shoe cover 1, and the ribs on the lower surface of the web plate 2 are connected to the first anti-slip part 10; the first anti-slip part 10 is provided with a plurality of protrusions 11 and a plurality of recesses 12; the lower surface of the shoe cover 1 is provided with second anti-slip parts on both sides, and the second anti-slip parts include a plurality of protrusions 13, the surface of which is relatively smooth, and its shape can be flexibly set. The shape and layout of the protrusions 11, recesses 12 and protrusions 13 in this embodiment can be found in [reference needed]. Figure 2 .
[0031] Furthermore, the shoe cover 1 has mounting parts 6 on both sides, which are used to connect to the two ends of the foot buckle. The opening of the shoe cover 1 is generally equipped with a foot buckle to secure the diver's instep and has a certain degree of elasticity. In this embodiment, the shoe cover 1 has mounting parts 6 on both sides, facilitating assembly with the foot buckle. Furthermore, the mounting parts 6 are integrally injection molded with the fin, resulting in a simple and reliable structure.
[0032] Furthermore, the end of the webbed fin 2 is provided with a through hole 5. This through hole 5 allows the fins to be easily hung up for convenient storage. Positioning the through hole 5 at the end of the webbed fin 2 reduces its impact on performance.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
