Description

Technical Field

[0001] The utility model relates to the technical field of swimming equipment, in particular to a snorkeling swimming fin. Background Art

[0002] A fin is a wearable device that provides additional propulsion force for the wearer during water activities and is widely used in swimming, diving, bodyboarding, prone surfing, surf rescue and swimming training. Due to its wide surface, it can provide strong forward power for swimming and diving.

[0003] Existing fins are relatively large in size. Although they can provide greater forward power when treading water, the fins will also be subject to corresponding resistance. To solve the above problems, the Chinese utility model patent with the publication number CN216536824U discloses a fin for swimming training, which includes a fin body. One end of the upper surface of the fin body is provided with a foot fixing sleeve, and two symmetrically distributed fasteners are arranged on the outer side of the foot fixing sleeve. A connecting column is fixedly connected to the middle of the inner side of the fastener, and the connecting column is connected through the through holes opened on both sides of the fixing sleeve. An elastic sheet is inlaid in the middle of the outer side of the fastener. A limiting frame with a "U" - shaped structure is fixedly connected to the inner side of the elastic sheet. A plurality of equally - spaced teeth are fixedly connected to the upper surface of the limiting frame. A strap passes through the fastener, and a plurality of convex teeth adapted to the teeth are arranged on both sides of the inner side of the strap. One end of the inner side of the fastener is provided with a pressing block with an arc - shaped structure, and the pressing block is attached to the outer side wall of the strap. A plurality of convex strips are fixedly connected to the outer side surface of the elastic sheet, and two symmetrically distributed reinforcing ribs are fixedly connected to one end of the outer side of the elastic sheet. A through hole is opened in the upper part of the foot fixing sleeve. Although part of the water entering the foot fixing sleeve can be discharged from this through hole, part of the water entering the foot fixing sleeve enters the space of the foot fixing sleeve near the bottom of the through hole, thus generating a certain resistance to forward movement and not meeting the increasing requirements of modern people for fins.

[0004] Therefore, the prior art needs to be improved. Content of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a snorkeling swimming fin with reduced resistance.

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0028] To facilitate the understanding of this embodiment, a snorkeling and swimming fin disclosed in the embodiments of the present utility model will be introduced in detail first.

[0029] Embodiment:

[0030] Please refer to Figures 1 - 3 , a snorkeling and swimming fin of the present application includes a fin body 100. A fin piece 101 is provided at the front end of the fin body 100, and a shoe body 102 is provided at the rear end of the fin body 100. The shoe body includes a shoe chamber structure and a sole structure, wherein the shoe chamber structure is integrally formed with the fin piece. The upper part of the shoe body 102, that is, the upper part of the shoe chamber structure, has an entrance 1021 for the wearer's foot to enter the shoe chamber; one end of the shoe body 102 close to the fin piece 101 is provided with a drainage opening 1022, and the size of the drainage opening 1022 is basically the same as the size of the end of the shoe chamber close to the fin piece 101, so as to be able to drain the water in the shoe chamber fastest; when swimming, the water entering the shoe body 102 flows out from the drainage opening 1022, effectively reducing the water resistance of the fin, and at the same time enabling the fin piece 101 to have a certain thrust on the water body, ensuring the wearing practice of the fin and effectively improving the practicability of the fin; a protrusion 1011 is provided along the width direction of the fin piece 101 close to the drainage opening 1022, and the cross-section of the protrusion 1011 is triangular, which is used to limit the toes of the wearer and is also beneficial to the flow of the water discharged from the drainage opening 1022.

[0031] As a preferred mode of this embodiment, both ends of the protrusion 1011 are bent towards the shoe body 102 to completely cover the toes of the wearer.

[0032] As a preferred embodiment of the present embodiment, two ribs 1012 are provided along the length direction on one side of the protrusion 1011 relative to the shoe body 102, and one end of the two ribs 1012 relative to the protrusion 101 is far from the central axis of the webbed piece 101; the cross-sections of the two ribs 1012 are triangular, and the height and width of the two ribs 1012 gradually decrease in the direction away from the protrusion 1011. Through the above structural design, the water body can further slide horizontally across the foot fin, increasing the swimming speed.

[0033] As a preferred embodiment of the present embodiment, an enhancement part 1023 is formed on the surface of the rear end of the shoe body 102, the rear end of the rear part of the shoe body (i.e., the shoe chamber structure), and the rear end of the rear part of the shoe chamber, for improving the strength of the shoe chamber structure.

[0034] As a preferred embodiment of the present embodiment, side edges 1024 are provided on both sides of the front end of the shoe body 102 near the enhancement part, and the side edges 1024 extend along the edge of the webbed piece 101 in the direction away from the shoe body 102; the height of the side edges 1024 reaches the highest at the position corresponding to the protrusion 1011, and then gradually decreases in the direction of the enhancement part 1023 and in the direction of the webbed piece 101 respectively. The ends of the two side edges 1024 away from the shoe body 102 are bent towards each other. When in use, the two side edges 1024 capture, temporarily hold and guide the water discharged towards the front edge of the webbed piece 101 during the upward and downward movement of the foot fin. The guiding of this water within a period of time reduces the loss of discharged water on each side of the surface of the webbed piece by capturing and holding a certain volume of water. This period of time is close to the time between each upward and downward movement within the side edges 1024, which increases the amount of water pushed towards the front edge of the webbed piece, thereby increasing the forward propulsion force provided during the wearer's kicking of the foot fin. The two side edges 1024 further provide increased traction and direction control by increasing the number of surfaces or edges in contact with the water and thus enable the wearer to use the foot fin to produce a "rudder-like" effect when being propelled forward by the waves.

[0035] As a preferred embodiment of the present embodiment, a diversion groove 1013 is provided near the free ends of the two ribs 1012 on the webbed piece 101. The diversion groove 1013 is arranged in an inverted convex platform structure. When treading water, the smaller end of the diversion groove 1013 is stressed, and less water flows through the diversion groove 1024, ensuring the treading water effect. When sliding forward, the water flows through the larger end of the diversion groove 1024, and more water flows through the diversion groove 1024, reducing the resistance received by the foot fin body 100 and further enhancing the practicality of the device.

[0036] In summary, through the above structural design, the present utility model solves the deficiencies in the prior art and has the characteristics of reasonable structure, reduced resistance, and strong practicality.

[0037] In addition, in the description of the embodiments of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" shall be understood in a broad sense.
