Fixing device for surfboard tail fin

Abstract

A fixing device for a surfboard tail fin comprises a fixing seat fixed to the bottom face of the tail portion of a surfboard. A strip-shaped fixing groove where the tail fin can be embedded is axially formed in the bottom of the fixing seat. Limiting notches are formed in the left inner wall and the right inner wall of the front portion of the strip-shaped fixing groove. Tail fin protruding shafts capable of supporting the bottom faces of the corresponding limiting notches are arranged on the two sides of the front portion of the top of the tail fin in a protruding manner. Openings allowing the tail fin protruding shafts to enter and exit out of the limiting notches are formed in the position, close to the limiting notches, of the side wall of the strip-shaped fixing groove. A locking mechanism capable of fixing the tail fin into the strip-shaped fixing groove when the tail fin protruding shafts are buckled to the limiting notches together is arranged in an inner cavity of the tail portion of the strip-shaped fixing groove. The fixing device has the beneficial effects that the tail fin is firmly fixed, a use effect is good, time and labor are saved in the installing and detaching processes, the structure is simple, and transportation or carrying is convenient; and the top face of the fixing seat is a rectangular board, the contact area of the fixing seat and the surfboard can be increased, the fixing seat and the rectangular board are of an integrated structure made of plastic integrally, the weight is small, the occupied space is small, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a surfing appliance, in particular to a fixing device for a tail fin of a surfboard. Background technique [0002] An existing Chinese utility model patent with the patent number CN201220523415.3 titled "Surfboard Tail Rudder Fixing Module" discloses a surfboard tail rudder fixing module, which is combined at the bottom of the surfboard to provide a connecting tail rudder, The rudder fixing module includes a strip-shaped fitting part, a resisting part formed around the bottom end of the fitting part, a tail rudder slot formed at the bottom end of the fitting part, and a plurality of fitting parts from the fitting part. The bottom end of the bottom part is connected obliquely to the screw hole on the side wall of the rudder slot. For this reason, the fitting part of the tail rudder fixing module can be used to embed the bottom surface of the surfboard, and the resisting part can be pressed against the bottom surface of the surf...

AI Technical Summary

Problems solved by technology

However, the device is only fixed by friction between the screw or screw rod and the tail rudder, which is prone to loosening, and the fixation is not firm enough. When removing the tail rudder, it is time-consuming and laborious to unscrew the screw or screw rod, which is very inconvenient to use. Therefore, the structure of the fixing module is still needs further improvement
