Problems solved by technology

Therefore, the installation of this kind of fin plate needs auxiliary tools such as screwdrivers to complete, and the replacement of the fin plate is inconvenient. In addition, due to the existence of the threaded hole, when sand or other small impurities enter the threaded hole, it will be difficult to install the fin plate. During the process of boarding, the screw will be stuck mechanically, which will prevent the fin board from being firmly fixed in the slot on the base board

Abstract

The invention relates to a fish fin. The fish fin comprises a baseplate and a fish fin plate, wherein a strip groove is formed in the baseplate. The fish fin is characterized in that outer convex guide shafts are arranged on the front and back end surfaces of one end of the bottom of the fish fin plate; vertical clamping grooves and transverse chutes are formed in the front and back side walls of one end of the strip groove; the guide shafts can be inserted through the clamping grooves and slipped into the chutes to form rotary connection; a buckle is rotationally connected into the other end of the strip groove through a rotating shaft part in the middle of the buckle; one end of the buckle extends outside the strip groove to form a wrenching part for manual wrenching, and the other end of the buckle extends into the strip groove to form a clamping part; and a clamping groove clamped with the clamping part is formed in the other end of the bottom of the fish fin plate. The fish fin can be conveniently assembled and disassembled without needing other tools, and is not prone to generating the blockage fault.

Description

Technical field [0001] The invention relates to an accessory for surfboard and SUP (STAND UP BOARD), in particular to a fish fin installed on the bottom surface of the surfboard and SUP to ensure the balance of the surfboard and SUP during sailing. Background technique [0002] Existing surfboards and SUPs must be equipped with one or more fins (also called tail rudders) on the bottom surface. Fish fins are necessary structures for surfboards and SUPs. They are often used for specific purposes and replaced with different fish. fin. Traditional surfboards and SUPs directly fix the fins on the bottom surface and cannot be replaced by users themselves, which no longer meets the requirements of use, especially those detachable or inflatable surfboards and SUPs that require a removable fish. Fins in order to reduce the volume during transportation. [0003] Recently, assembling structures that provide fins for mounting on surfboards and SUPs are developing towards modular assembly. Th...
