Abstract
Description
Technical Field
[0001] This utility model relates to the field of surfboard technology, and in particular to a durable V-shaped surfboard. Background Technology
[0002] A surfboard is a piece of equipment used for surfing. Modern surfboards are typically 1.5 to 2.7 meters long, about 60 centimeters wide, and 7 to 10 centimeters thick. They are lightweight and flat, slightly narrower at both ends, and have a stabilizing tail fin at the bottom rear. To increase friction, a waxy coating is applied to the surface. The total weight of a surfboard is only 11 to 26 kilograms.
[0003] Existing surfboards are generally of a one-piece structure, meaning the board body is fixed to the tail fin. This makes the tail fin prone to damage after prolonged use, eventually rendering the entire surfboard unusable, reducing its lifespan, increasing operating costs, and resulting in low durability. Utility Model Content
[0004] The present invention aims to provide a durable V-shaped surfboard that overcomes or at least partially solves the above-mentioned problems.
[0005] To achieve the above objectives, the technical solution of this utility model is specifically implemented as follows:
[0006] This utility model provides a durable V-shaped surfboard, including a V-shaped board body, a triangular connecting plate, and a tail fin. The triangular connecting plate is matched and disposed at the triangular notch of the V-shaped board body, and a stop bar is provided on the lower side of the triangular connecting plate and the V-shaped board body. The stop bar is fixedly connected to the V-shaped board body and the triangular connecting plate by bolts. A guide groove is provided inside the triangular connecting plate, and a guide rail is slidably connected in the guide groove. The guide groove is disposed between the triangular connecting plate and the V-shaped board body. The tail fin is integrally connected to the lower side of the guide rail, and the tail fin is arranged perpendicularly to the triangular connecting plate.
[0007] As a further embodiment of this utility model, the interior of the V-shaped plate is integrally connected with a positioning protrusion, and the upper side of the triangular connecting plate is provided with a positioning hole, and the positioning protrusion is matched and disposed in the positioning hole.
[0008] As a further embodiment of this utility model, notches and grooves are provided on the lower sides of both the V-shaped plate and the triangular connecting plate, and the stop bar is matched and disposed in the notches and grooves.
[0009] This invention provides a durable V-shaped surfboard with the following advantages: the assembly method facilitates easy disassembly and replacement, simplifies operation, reduces usage costs, and improves the durability and lifespan of the surfboard. Attached Figure Description
[0010] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0016] See Figure 1-3 This utility model provides a durable V-shaped surfboard, including a V-shaped board body 1, a triangular connecting plate 2, and a tail fin 5. The triangular connecting plate 2 is matched and disposed at the triangular notch of the V-shaped board body 1, and a stop bar 3 is provided on the lower side of the triangular connecting plate 2 and the V-shaped board body 1. The stop bar 3 is fixedly connected to the V-shaped board body 1 and the triangular connecting plate 2 by bolts. A guide groove 6 is provided inside the triangular connecting plate 2, and a guide rail 4 is slidably connected in the guide groove 6. The guide groove 6 is disposed between the triangular connecting plate 2 and the V-shaped board body 1. The tail fin 5 is integrally connected to the lower side of the guide rail 4, and the tail fin 5 is arranged perpendicularly to the triangular connecting plate 2.
[0017] The V-shaped plate 1 has an integrally connected positioning protrusion 11 inside. The upper side of the triangular connecting plate 2 has a positioning hole 21, and the positioning protrusion 11 is matched and set in the positioning hole 21. The lower sides of both the V-shaped plate 1 and the triangular connecting plate 2 have notches, and the stop bar 3 is matched and set in the notches, which can align the triangular connecting plate 2 with the V-shaped plate 1 and ensure the stability of the connection.
[0018] In use, the tail fin 5 is slidably connected to the guide groove 6 via the guide rail 4. Then, the triangular connecting plate 2 is aligned and set at the triangular notch of the V-shaped plate 1. Then, the stop bar 3 is placed at the bottom end of the triangular connecting plate 2 of the V-shaped plate 1 and fixed with bolts. The tail fin 5 can be stably installed on the lower side of the V-shaped plate 1, thus achieving the purpose of combined installation.
[0019] When the tail fin 5 is damaged, simply loosen the bolts, separate the triangular connecting plate 2 from the V-shaped board body 1, and then replace the tail fin 5 with a new one. The operation is simple and the replacement is convenient, which reduces the cost of use and improves the durability and service life of the surfboard.
[0020] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
