Technical Field

[0001] The utility model relates to the technical field of water ski board manufacturing, and particularly to a fin structure on a water ski board. Background Art

[0002] There is a Chinese invention patent application with the application number CN202110995469.3 and the name "A New Type of Water Ski Board", which discloses a new type of water ski board, including a rear race board. The shape of the rear race board is an arc shape that is narrow at the front and wide at the rear. A base and a holder are installed on the top wall of the rear race board. The base is located at the rear end of the rear race board, and the holder is located in the middle position of the rear race board. A wave breaker is installed at the front end of the rear race board, and the direction of the wave breaker is set perpendicular to the direction of the rear race board. A limiting mechanism that mutually restricts the wave breaker is opened on the top wall of the rear race board. A receiving groove is opened on the bottom wall of the rear race board, and the receiving groove is located in the rear half of the bottom wall of the rear race board. A tail wing is installed in the receiving groove, and a movable mechanism is installed in the tail wing. A receiving mechanism is opened in the rear race board, and the receiving mechanism and the receiving groove are on the same axis. The receiving mechanism is used to receive the tail wing. The water ski board in this invention not only maintains the strength of the rear race board on the premise of being relatively light in weight, but also the tail wing can be retracted into the receiving groove when hitting a rock, protecting the safety of the tail wing. However, the tail wing structure of this water ski board is still relatively single and cannot attract children, and the entertainment effect is relatively average. Therefore, the structure of this water ski board still needs to be further improved. Summary of the Invention

[0004] The technical solution adopted by the utility model to solve the above technical problem is as follows: The fin structure on this water ski board includes a fin body that can be connected to the board body of the water ski board. It is characterized in that fin threaded holes are arranged at intervals at the end of the fin body, the fin body is screwed to the board body, a fin through hole is arranged on the fin body, and an impeller that can rotate relative to the fin body as the board body moves is arranged in the fin through hole.

[0005] As an improvement, the fin body can preferably be in a blade shape, and an arc-shaped concave part is arranged at the tail end of the fin body.

[0006] Further improvement, the fin through hole can preferably be arranged at the rear part of the fin close to the arc-shaped concave part.

[0007] As an improvement, the impeller can preferably be detachably connected in the fin through hole.

[0008] For further improvement, a fixing groove may preferably be provided on the side wall of the fin body corresponding to the through hole of the fin. A connecting cover is arranged in the fixing groove, and a connecting rod is clamped between the fixing groove and the connecting cover. The impeller is sleeved on the connecting rod.

[0009] For further improvement, a wear-resistant sleeve may preferably be sleeved on the connecting rod, and the impeller is sleeved on the wear-resistant sleeve.

[0010] For further improvement, a limiting sleeve may preferably be sleeved on the connecting rod, and the limiting sleeve abuts against the wear-resistant sleeve.

[0011] For further improvement, the limiting sleeve may preferably have the same diameter as the wear-resistant sleeve. A fitting recess is provided on the fixing groove, and the limiting sleeve is stuck on the fitting recess.

[0012] For further improvement, a connecting recess may preferably be provided on the fixing groove, and a cover projection is provided on the connecting cover. The cover projection is inserted into the corresponding connecting recess.

[0013] For further improvement, the outer wall of the connecting cover may preferably be a smooth arc surface.

[0014] Compared with the prior art, the advantages of the present utility model are as follows: An impeller is provided on the fin body. When the water ski board moves, the impeller will rotate automatically under the action of water flow, which has a strong entertainment effect and is suitable for children to swim and play with each other, and has a good use effect; The impeller is installed on the fin body, and the installation and disassembly are very convenient.
