[0023] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0024] Embodiment 1:

[0025] like Figure 1 As shown, the present invention provides an inflatable paddle board, including an inflatable paddle board 1, an inflation port 7 is provided on the inflatable paddle board 1, a fish fin 2 is provided at the tail of the bottom surface of the inflatable paddle board 1, and the connection between the fish fin 2 and the inflatable paddle board 1 is integrally formed. An air bag 3 is provided in the fish fin 2, and the air cavity of the air bag 3 is connected to the air cavity of the inflatable paddle board 1. Before surfing, when the inflatable paddle board 1 is inflated through the inflation port 7, the air pressure generated can prop up the fish fin 2 to maintain the structural strength required for surfing.

[0026] like Figure 2 As shown, in one embodiment, the chamber of the airbag 3 fills the entire fin 2, and the frame of the fin 2 is streamlined along the forward direction of the inflatable paddle board 1 to reduce water flow resistance.

[0027] like Figure 3 As shown, in another embodiment, there are multiple airbags 3 distributed on the fish fin 2, and the shape of each airbag 3 is an elongated version of the overall shape of the fish fin 2.

[0028] Embodiment 2:

[0029] The present invention provides an inflatable paddle board, comprising an inflatable paddle board 1, an inflatable port 7 is provided on the inflatable paddle board 1, a fish fin 2 is provided at the tail of the bottom surface of the inflatable paddle board 1, and the fish fin 2 is integrally formed with the inflatable paddle board 1. Figure 4As shown, the border of the fish fin 2 is provided with a boundary rib 5, and a reinforcement rib 6 is provided inside the boundary rib 5. The boundary rib 5 is made of a deformable hard material, such as PVC plastic; the reinforcement rib 6 is made of a non-deformable hard material, such as metal. Figure 5 As shown, protrusions 20 are provided at both ends of the reinforcing rib 6, and grooves matching the protrusions 20 are provided at the position where the reinforcing rib 6 is installed on the boundary rib 5, so as to realize the removal and installation of the reinforcing rib 6. Before surfing, align the protrusions 20 with the grooves, install the reinforcing rib 6 on the boundary rib 5, and support the fish fin 2 by the structural strength of the reinforcing rib 6; when storing, remove the reinforcing rib 6 from the boundary rib 5, and deflate the inflatable paddle board 1. The material of the boundary rib 5 allows the fish fin 2 to be bent without damaging its own structure.

[0030] Embodiment 3:

[0031] Further, on the basis of Example 2, as Figure 6-8 As shown, the boundary rib 5 is composed of a first fixed rib 9, a second fixed rib 10, a first movable rib 11 and a second movable rib 12 that can be formed into the shape of a fish fin 2. The first fixed rib 9 and the second fixed rib 10 are both provided with a retractable slide 13, and the bottoms of the two retractable slides 13 are provided with sinks 14 extending to both sides of the fish fin 2. The first fixed rib 9 and the second fixed rib 10 are fixedly connected to the fish fin 2, one end of the second movable rib 12 is hinged to the bottom of the second fixed rib 10, and the other end is provided with a first sliding member 21, and the bottom of the first fixed rib 9 is provided with a second sliding member 22. The reinforcement rib 6 includes a first telescopic rib 16 and a second telescopic rib 17, the two retractable slides 13 are slidably matched with the first telescopic rib 16, the first movable rib 11 is provided with a driven slide 15, one end of the second telescopic rib 17 is provided with a third sliding member 4, and the other end of the second telescopic rib 17 is hinged to the first telescopic rib 16. The first sliding member 21 , the second sliding member 22 and the third sliding member 4 are all located inside the driven sliding groove 15 and slide, and the second sliding member 22 is located between the first sliding member 21 and the third sliding member 4 .

[0032] like Fig. 9 As shown, the first telescopic rib 16 and the second telescopic rib 17 are both provided with springs 19 for providing elastic force for outward expansion, and the first telescopic rib 16 is also fixedly provided with a toggle plate 8, and the toggle plate 8 is provided with two exposed contraction rods 18, which are fixedly connected to both ends of the spring 19 and are used to compress the length of the spring 19. The distance L between the second sliding member 22 of the first fixed rib 9 and the hinge point of the second fixed rib 10 is greater than the rotation radius R of the second fixed rib 10 around the hinge point of the second fixed rib 10, ensuring that the second movable rib 12 can rotate normally clockwise around the hinge point of the second fixed rib 10 without being affected.

[0033] Before surfing, adjust the toggle plate 8 downward, the first telescopic rib 16 moves downward along the retractable chute 13, and at the same time drives the third sliding member 4 of the second telescopic rib 17 to move along the driven chute 15, thereby lifting the first movable rib 11 and moving it downward along the path of the driven chute 15 as a whole, and the second movable rib 12 rotates clockwise to open the boundary rib 5. When the first telescopic rib 16 moves to the bottom of the retractable chute 13, under the expansion of the spring 19, the sliding members at both ends of the first telescopic rib 16 will be drawn into the sink 14, and then the toggle plate 8 is finely adjusted upward, and the first telescopic rib 16 is clamped in the sink 14 due to the elastic force of the spring 19 expanding outward, so that the position of the first telescopic rib 16 itself no longer changes; at the same time, the third sliding member 4 will move to the lowest point of the driven chute 15, and be located at the same position as the first sliding member 21, completing the secondary fixation of the reinforcement rib 6 to the boundary rib 5, and ensuring the structural strength of the fish fin 2 itself.

[0034] When storing, the retracting rod 18 is squeezed inward to move the toggle plate 8 upward, and the spring 19 is further contracted, so that the sliding parts at both ends of the first telescopic rib 16 slide out of the sink 14 and move upward along the storage and release chute 13, and at the same time drive the third sliding part 4 of the second telescopic rib 17 to move along the driven chute 15, and then pull the first movable rib 11 to move upward along the path of the driven chute 15 as a whole, and the second movable rib 12 rotates counterclockwise to store the boundary rib 5. When the first telescopic rib 16 moves to the top of the storage and release chute 13, the first movable rib 11 overlaps with the first fixed rib 9, and the second movable rib 12 rotates to between the first fixed rib 9 and the second fixed rib 10, and the first sliding part 21 and the third sliding part 4 are located in the same position side by side with the second sliding part 22. By storing the first movable rib 11 and the second movable rib 12 as the tip of the fin 2, the boundary rib 5 can be protected to prevent the fin 2 from being bent multiple times and damaging the boundary rib 5 when the inflatable paddle board 1 is stored.
