Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to a multi-stage drag-reducing progressive water-guiding hole frog shoe plate. Background Technology

[0002] Fins are a common piece of equipment for water activities, especially diving, where almost everyone wears fins. When the user kicks, the webbed parts of the fin bend, and the rebound force of the webbed parts generates forward force to help the user move forward.

[0003] Fins are widely loved by diving enthusiasts and professional athletes. They provide tremendous thrust when divers kick, helping them move forward. However, when divers pull their legs back, they also encounter water resistance, which hinders their forward movement. This is because fins come into contact with water, and a large amount of water enters the fins, increasing their resistance. To address this, we propose a multi-stage drag-reducing progressive water-guiding fin plate. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this invention is to provide a multi-stage, progressively sized water-guiding hole frog shoe plate to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage drag-reducing progressive water-guiding hole fin plate, comprising a fin plate, wherein a plurality of first water-guiding holes are uniformly provided on the surface of the fin plate, the plurality of first water-guiding holes are symmetrically distributed on both sides of the edge of the fin plate, mounting blocks are symmetrically rotatably connected to the side of the fin plate, and fins are fixedly installed between two mounting blocks, wherein first grooves are symmetrically provided on the bottom of the fin plate, and adjusting plates are slidably connected inside the two first grooves, the surface of the adjusting plates is in slidable contact with the bottom of the fin plate, a plurality of second water-guiding holes are uniformly provided on the surface of the adjusting plates, the plurality of second water-guiding holes are positioned opposite the plurality of first water-guiding holes, and a linkage component is provided at one end of the fins.

[0007] Furthermore, the linkage component includes a mounting plate, a rotating rod, a movement slide, and a second slide groove. The mounting plate is symmetrically fixedly mounted on one end of the flipper, and a rotating rod is rotatably connected between the two mounting plates. The bottom of the shoe plate is provided with a second slide groove, and a movement slide is slidably connected inside the second slide groove. The inner wall of the movement slide is slidably connected to the end of the rotating rod, and the side of the movement slide is fixedly connected to the end of the adjustment plate.

[0008] Furthermore, the bottom of the shoe plate is provided with a limiting strip, which is positioned directly opposite the fins and contacts the upper surface of the fins.

[0009] Furthermore, the diameter of the first water guide hole is equal to the diameter of the second water guide hole, and the length of the second chute is equal to the radius of the first water guide hole.

[0010] Furthermore, both the mounting block and the end of the flipper are arc-shaped.

[0011] Furthermore, the surface of the adjustment plate is provided with a shark fin.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This fin board reduces resistance when the diver pulls their legs back by setting a first water guide hole, helping the diver move forward. When the diver kicks, the fins rotate relative to each other, and the surface of the fins contacts the limit strip. Under the action of the linkage component, the first water guide hole closes, and the water guide hole stops guiding water. This increases the thrust when the athlete kicks, helping the diver move forward. Attached Figure Description

[0022] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0023] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] This utility model provides, for example Figure 1-4The multi-stage drag-reducing progressive water-guiding perforated fin plate shown includes a fin plate 1. The surface of the fin plate 1 is uniformly provided with a plurality of first water-guiding holes 2, which are symmetrically distributed on both sides of the edge of the fin plate 1. A mounting block 3 is symmetrically rotatably connected to the side of the fin plate 1, and a fin 4 is fixedly installed between two mounting blocks 3. The bottom of the fin plate 1 is symmetrically provided with first sliding grooves 5, and an adjusting plate 6 is slidably connected inside two of the first sliding grooves 5. The surface of the adjusting plate 6 slides in contact with the bottom of the fin plate 1. The surface of the adjusting plate 6 is uniformly provided with a plurality of second water-guiding holes 7, which are positioned opposite to the plurality of first water-guiding holes 2. A linkage component is provided at one end of the fin 4. When this device is in operation, the diver puts the fin on... When the athlete kicks the water, the fins 4 experience forward resistance. At this time, the fins 4 rotate to a position parallel to the shoe plate, and the limiting strip 12 contacts the surface of the fins 4. The second water guide hole 7 of the adjusting plate 6 does not coincide with the first water guide hole 2. At this time, the first water guide hole 2 and the second water guide hole 7 lose their water guiding function, increasing the thrust when the diver kicks the water. When the diver pulls his legs back, the fins 4 rotate, driving the rotating rod 9 to move. At this time, the end of the rotating rod 9 slides in the movement slide 11, and the movement slide 11 also slides in the second slide groove 10, driving the adjusting plate 6 to slide in the first slide groove 5. At this time, the first water guide hole 2 coincides with the second water guide hole 7, and the shoe plate 1 begins to guide water, reducing the resistance when the athlete pulls his legs back.

[0025] The linkage assembly includes a mounting plate 8, a rotating rod 9, a movement slide 11, and a second slide groove 10. The mounting plates 8 are symmetrically fixed at one end of the flippers 4, and the rotating rod 9 is rotatably connected between the two mounting plates 8. The bottom of the shoe plate 1 is provided with a second slide groove 10, and the movement slide 11 is slidably connected inside the second slide groove 10. The inner wall of the movement slide 11 is slidably connected to the end of the rotating rod 9, and the side of the movement slide 11 is fixedly connected to the end of the adjustment plate 6. When the flippers 4 rotate, it drives the rotating rod 9 to move. At this time, the end of the rotating rod 9 slides in the movement slide 11, and the movement slide 11 also slides in the second slide groove 10, which drives the adjustment plate 6 to slide in the first slide groove 5.

[0026] The bottom of the shoe plate 1 is provided with a limiting strip 12, which is positioned directly opposite the fin 4. The limiting strip 12 contacts the upper surface of the fin 4. When the fin 4 rotates to a position parallel to the shoe plate, the limiting strip 12 contacts the surface of the fin 4.

[0027] The diameter of the first water guide hole 2 is equal to the diameter of the second water guide hole 7, the length of the second sliding groove 10 is equal to the radius of the first water guide hole 2, the first water guide hole 2 and the second water guide hole 7 coincide, and the shoe plate 1 begins to guide water.

[0028] Both the mounting block 3 and the fins 4 have arc-shaped ends to reduce the resistance of the component in water.

[0029] The surface of the adjustment plate 6 is provided with a shark fin to reduce the resistance of the linkage component in water.

[0030] In summary, when using this fin board, the diver puts the board on their feet. When the athlete kicks, the fins 4 experience forward resistance. At this time, the fins 4 rotate to a position parallel to the fin board, and the limiting strip 12 contacts the surface of the fins 4. The second water guide hole 7 of the adjusting plate 6 does not coincide with the first water guide hole 2. At this time, the first water guide hole 2 and the second water guide hole 7 lose their water guiding function, increasing the thrust when the diver kicks. When the diver pulls their legs back, the fins 4 rotate, driving the rotating rod 9 to move. At this time, the end of the rotating rod 9 slides in the movement slide 11, and the movement slide 11 also slides in the second slide groove 10, driving the adjusting plate 6 to slide in the first slide groove 5. At this time, the first water guide hole 2 coincides with the second water guide hole 7, and the fin board 1 begins to guide water, reducing the resistance when the athlete pulls their legs back. This completes the entire workflow.
