[0025] The fixing component for convenient surfboard tail fin installation provided by this utility model, compared with the prior art, enables the tail fin plate 2 to be adjusted in position within the slot seat 101, and can be adjusted according to the user's needs.
[0026] Please refer to another embodiment of this utility model as well. Figures 1 to 4Support components 3 are installed on both sides of the interior of the base plate 1. The support components 3 include a slide rod 301, which is slidably connected to the interior of the slot seat 101. One end of the slide rod 301 is fixedly connected to a support block 302, which is slidably connected to the interior of the placement groove 102. The support block 302 is limited to sliding within the placement groove 102, and its outer wall fits against the outer wall of the insert 201. The other end of the slide rod 301 is fixedly connected to a limiting plate 303. The slide rod 301 is used in conjunction with the limiting plate 303 to limit its sliding within the slot seat 101. The outer wall of the slide rod 301 is fitted with... A spring 304 is provided, with one end of the spring 304 fixedly connected to the inside of the slot seat 101 and the other end of the spring 304 fixedly connected to the inside of the limiting plate 303. The spring 304 provides support for the limiting plate 303, the slide rod 301, and the support block 302, and at the same time enables flexible adjustment of the slide rod 301 and the support block 302. The slide rod 301, the support block 302, and the limiting plate 303 are made of glass fiber, which provides corrosion resistance. The spring 304 is made of stainless steel, which provides corrosion resistance.
[0027] Working principle: The base plate 1 is installed and fixed on the surfboard through the positioning hole 107. When the tail fin 2 and slot 101 need to be installed, the limiting plate 303 drives the sliding rod 301 to pull outward, causing the support block 302 to slide. Then, the insertion block 201 at the bottom of the tail fin 2 is placed inside the placement slot 102. The limiting plate 303 is released, and the elasticity of the spring 304 drives the limiting plate 303, sliding rod 301 and support block 302 to return to their original positions, causing the support block 302 and insertion block 201 to... The surface is fitted together, and the outer wall of the insert 201 is supported by the support block 302. Then, two locking blocks 104 are respectively inserted through the sliding groove 103 and locked inside the groove 202. Then, the bolt 105 is threaded into the inside of the locking block 104, and then the bolt 105 is threaded into the corresponding threaded groove 106, so that the bolt 105 limits and fixes the locking block 104 inside the groove 202, thereby realizing the limiting and fixing of the tail fin plate 2 and the slot seat 101. When the user uses the punch... When surfing, the position of the tail fin 2 can be adjusted as needed. During adjustment, rotating the bolt 105 causes it to move upward and disengage from the threaded groove 106. Then, sliding the locking block 104 causes the insert block 201 and tail fin 2 to slide. During the sliding of the insert block 201, one of the support blocks 302 will slide, while the other support block 302 will return to its original position and continue to be in contact with the outer wall of the insert block 201 due to the elasticity of the spring 304. This ensures that the two support blocks 302 always remain in contact with the outer wall of the insert block 201, supporting the insert block 201. After the locking block 104 causes the insert block 201 and tail fin 2 to slide to a suitable distance, the bolt 105 moves and aligns with the corresponding threaded groove 106. Rotating the bolt 105 causes it to be threaded into the corresponding threaded groove 106, thus limiting and fixing the locking block 104 and the insert block 201. This allows for adjustment of the installation position of the tail fin 2 and the insert block 201, improving the practicality of the surfboard and enhancing the user experience.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
