DETAILED DESCRIPTION OF THE EMBODIMENTS

(6) Technical solutions of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the disclosure, all other embodiments made by those skilled in the art without sparing any creative effort should fall within the protection scope of the present disclosure.

(7) The purpose of the present disclosure is to provide a paddle fin structure to solve the problems of unstable connection and poor water distribution effect of the existing paddle fin structure.

(8) In order that the above objects, features and advantages of the present disclosure may be more clearly understood, the present disclosure will be described in further detail with reference to the drawings and the detailed description thereof.

Embodiment 1

(9) Referring to FIG. 1-3, the embodiment provides a paddle fin structure, comprising a fin body 1 and a base 2, the fin body 1 is inserted into the base 2, and the fin body 1 and the base 2 are connected by a pin.

(10) Further, the fin body 1 and the base 2 are made of PA6 material, and the pin is made of ABS material.

(11) Further, as shown in FIG. 1, the bottom surface of the fin body 1 is provided with a connecting part 101, and the connecting part 101 is provided with a fastening hook 102 and an insertion hole 103 side by side. Compared with the prior art, in the present disclosure, the buckle type link mode is adopted, the stress direction of the bottom of the fin body 1 can be changed, the structural strength is increase, and the bottom is not easy to deform.

(12) Further, the front portion of the fin body 1 has a structure with a thick middle portion and two thin sides, so that the flowing water resistance can be reduced and the traveling speed can be improved.

(13) Further, the rear portion of the fin body 1 is provided with three guiding grooves 104, the angles from bottom to top are respectively 13 degrees, 9.5 degrees and 9 degrees. In that course of the flow, the flow resistance is reduced and the traveling speed is increase by proper angle diversion.

(14) For understanding, it is noted here that the location of guide grooves 104 of the fin body 1 is limited to the rear part of fin body 1. In the present disclosure, backward refers to the horizontal direction towards the guide grooves 104.

(15) Further, as shown in FIG. 2, the middle of the upper surface of the base 2 is provided with a connecting groove 201, the connecting groove 201 is engaged with the connecting part 101, the connecting groove 201 is provided with a card groove 202 engaged with the fastening hook 102. In addition, that side of the connecting groove 201 is provided with a socket 203 opposite to the insertion hole 103, and the pin is insert into the insertion hole 103 through the socket 203, which is more convenient and secure than the traditional wired connection. In order to fully consider that usage habits of human body, the position width of the socket 203 is just the size of the palm and thumb of a normal adult, and the structure is optimized to improve the user experience.

(16) Further, the socket 203 is provided with a hidden buckle grill 204, which can be hooked to the fastening hook, so that the fastening hook is not easy to fall off and is easy to store.

(17) Further, as shown in FIG. 3, the bottom surface of the base 2 is provided with a honeycomb structure 205, the thickness of the bottom is increased, and the original flat bottom is changed into a honeycomb thick bottom, so that the force can be dispersed in both transverse and longitudinal directions to ensure that it is not easy to deform.

(18) Further, the bottom of the base 2 is provided with a groove 206 for the purpose of allowing gas to flow through the bottom when glued on the paddle board so as not to thermally expand the blocking gas due to the high temperature in the summer, so that the paddle fin structure to bulge and can not to be used.

(19) The present disclosure provides a paddle fin structure, which is used by gluing the base 2 to a proper position of the paddle, inserting the connecting part 101 of the fin 1 into the connecting groove 201 of the base 2, and engaging the buckle 102 with the card groove 202. At this time, the insertion hole 103 and the socket 203 are positioned opposite to each other, and a stable connection can be achieved by inserting the pin.

(20) In the present disclosure, the principle and implementation mode of the present disclosure are illustrated by using specific example, and the above examples are only for helping to understand the method and the core idea of the present disclosure; meanwhile, for those of ordinary skill in the art, there will be changes in the specific embodiments and the scope of application according to the idea of the present disclosure.
