For example, referring to fig. 6, since the paddle body 10 takes the extending direction of the boss 20 as a central axis, the paddle bodies 10 at both sides of the boss 20 can tilt up in the thickness direction (as shown in the Y direction in fig. 6) with respect to the boss 20 to form a V-shaped structure. Thus, referring to fig. 12, embodiments of the present utility model may also form an arch structure as arch bridge 3. Illustratively, referring to fig. 12 (b), the second surface 12 is provided with two notches 111, and edges of the notches 111 are attached by two connecting pieces 30, so that the first surface 11 forms two protrusions 20. Referring to fig. 12 (c), the first surface 11 is provided with two notches 111, and is connected to edges of the notches 111 through two connecting pieces 30, so that the first surface 11 forms two protrusions 20. It should be noted that, the arch bridge 3 according to the embodiment of the present utility model is not limited to the above-mentioned structure, and a structure in which a single or multiple protrusions 20 are provided to form the arch bridge 3 falls within the scope of the present utility model.

In some possible embodiments, the manufacturing process of the paddle board 1 according to the embodiment of the present utility model may further include adhering a foamed anti-slip pad with a hardness of 35Pa to 60Pa above the first surface 11 of the paddle board body 10, so as to increase the friction force under the foot of the user, and also be softer and more comfortable. Two or more stainless steel D-rings are provided in the middle area of the first surface 11 of the paddle body 10 for securing the seat, and a seat securing means for providing a rest for the user. 4 or more elastic rope connecting pieces are arranged at the front end of the first surface 11 of the paddle board body 10, and the elastic ropes form a storage area, so that a user can conveniently place articles. Two handles are arranged at the middle part and the tail part of the paddle board body 10, so that the paddle board is convenient for a user to carry.

The embodiment of the utility model utilizes the convex part 20 which is convex inwards on the second surface 12 of the paddle board 1, which is contacted with the water surface, to improve the water diversion and direction control capability of the paddle board 1. Mainly adopts a mode of attaching the edges of the first part 110 and the second part 120 together by using the connecting sheet 30 after the notch 111 is formed on the first surface 11, a mode of connecting the edges of the first part 110 and the second part 120 together by using the connecting sheet 30 after the notch 111 is formed on the second surface 12, a mode of attaching the connecting sheet 30 to the edges of the first part 110 and the second part 120 together, and a mode of forming the first auxiliary air chamber 15 on the second surface 12, or a mode of forming the second auxiliary air chamber 16 independent of the paddle air chamber 14 on the second surface 12, so as to act as a keel in the process of moving the paddle 1 in water.

While the utility model has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a further detailed description of the utility model with reference to specific embodiments, and it is not intended to limit the practice of the utility model to those descriptions. Various changes in form and detail may be made therein by those skilled in the art, including a few simple inferences or alternatives, without departing from the spirit and scope of the present utility model.
