Description

Technical Field

[0001] This utility model belongs to the technical field of surfboard accessories, and more specifically, it relates to a foldable surfboard fin base. Background Technology

[0002] Surfing is an extreme sport that uses ocean waves as power and surfboards to glide on the water. It combines skill, spectacle, and challenge. The surfboard is the core equipment of surfing. The front and rear ends of the surfboard are slightly narrower, and there is a fin at the rear that plays a stabilizing role. The fin is usually set perpendicular to the board.

[0003] The fin base of a surfboard is a key component that connects the fin to the surfboard. Existing fin bases are generally fixed structures that do not have a folding function, take up a lot of space, and are inconvenient to carry and store, making them rather inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a foldable surfboard fin base that is foldable.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a foldable surfboard fin base is provided, including a first base and a second base. A thin film hinge is fixedly connected to the lower connection of the first base and the second base. A first limiting shell is fixedly connected to the top of the first base, and a second limiting shell is fixedly connected to the top of the second base. A fin is placed inside the second limiting shell and the first limiting shell. The first base includes a first seat body. A first fixing hole is provided inside the first seat body. A first magnetic block is fixedly connected to the lower part of the first seat body.

[0006] Optionally, the second base includes a second seat body, the interior of which is provided with a second fixing hole, and a second magnetic block is fixedly connected to the lower part of the second seat body.

[0007] Optionally, the second limiting shell includes a second housing fixedly connected to the top of the second base body, the interior of the second housing is provided with a second slot, and the front and rear sides of the interior of the second housing are provided with limiting grooves.

[0008] Optionally, the fin includes a post placed inside the second limiting shell and the first limiting shell. Limiting strips are fixedly connected to both the front and rear sides of the post. A connecting plate is fixedly connected to the top of the post, and the fin body is fixedly connected to the top of the connecting plate.

[0009] Optionally, the first limiting shell includes a first housing fixedly connected to the top of the first base, and the interior of the first housing is provided with a first slot.

[0010] Optionally, the magnetism of the first magnetic block is opposite to that of the second magnetic block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model is provided with a first base, a second base, and a film hinge, which can fold the base. The film hinge is made of thermoplastic polyurethane with a thickness of 1 mm, which allows the first base and the second base to rotate relative to each other, so that the lower parts of the first base and the second base can fit together, thereby folding the base, reducing the space occupied by the base, and making it easy to carry and store the base. After folding, the first magnetic block and the second magnetic block can be attracted together, ensuring that the folded base is more stable.

[0013] 2. This utility model is provided with a first limiting shell and a second limiting shell. By aligning the insertion post with the second slot and the limiting strip with the limiting groove, the insertion post and the limiting strip can be inserted into the second slot and the limiting groove of the folded base. After the insertion post and the limiting strip are fully inserted, the base is unfolded so that the insertion post enters the first slot. Then, the base can be fixed to the surfboard with bolts through the first fixing hole and the second fixing hole. Under the limiting action of the limiting groove, the insertion post cannot move upward. Under the blocking action of the first shell and the second shell, the insertion post cannot move left or right, thereby fixing the fin and ensuring the stability of the fin during use. When disassembling, unscrew the bolts and rotate the first base to disengage the insertion post from the first slot, so that the fin can be pulled out from the second base for easy replacement.
