Detailed Description

The technical solution of the present invention will be further described and explained with reference to the accompanying drawings. The terms of orientation used in the detailed description are only used to facilitate a person skilled in the art to understand the technical solutions described in the present application according to the visual orientations shown in the drawings. Unless otherwise specifically stated or limited, the terms "disposed," "mounted," "connected," and the like are to be construed broadly and their specific meanings in the present disclosure may be understood by those skilled in the art as appropriate.

As shown in fig. 1 to 7, a tail fin for a surfboard comprises a body 1, wherein the body 1 is fixedly connected to the bottom of the surfboard through a connecting bottom end 5, and the structure is shown in fig. 1; certainly, the tail fin connecting piece 20 and the tail fin clamping piece 21 can be additionally arranged at the bottom end of the tail fin and clamped in the seat body of the surfing board or the groove of the surfing board, the tail fin connecting piece 20 plays a limiting role, the tail fin clamping piece 21 plays a role in fixing the position in a screwing mode, and other detachable connecting modes, such as screw connection, clamping of the clamping pieces, insertion and the like, can be determined by the technical personnel in the field according to actual conditions. The body 1 is processed with hollow out construction 2 in its middle part position department, and hollow out construction 2 selects the structure shape that has the aesthetic feeling according to actual need. The front end part 3 of the body 1 protrudes towards the direction far away from the hollow structure 2, the rear end part 4 of the body 1 bends towards the direction close to the hollow structure 2, and the front end part 3, the rear end part 4 and the connecting position of the top ends of the front end part 3 and the rear end part 4 all adopt a smooth transition structural form. Because the hollow structure 2 is added on the tail fin, although a certain structural form for reinforcing the hollow structure 2 is added, the overall weight is still lower compared with the tail fin without the hollow structure. The utility model discloses in hollow out construction 2 that increases can also increase the flow that the water body passed the tail fin, reduce the resistance between rivers and the tail fin when turning to, for the surfing provides better steering capacity, also reduced partly surfboard stability simultaneously, this just makes surfing fan or surfer when using the fretwork tail fin, needs have better equilibrium and operational capability, and then can improve surfing's stimulation degree.

Body 1 can adopt left body 1A, the concatenation of right body 1B to constitute, left side body 1A's outer border position department is fixed with rather than integrative border connection arch 7, border connection arch 7 sets up on left body 1A along left body 1A's outer border protrusion. The edge connecting bulge 7 forms a left groove 6 for accommodating the colloid structure on the left body 1A. The left body 1A is further provided with a left reinforcing part 9 which is integrated with the hollow structure 2 and distributed along the edge of the hollow structure 2 at the edge position of the hollow structure 2, and a left reinforcing caulking groove 16 is arranged at the connecting position of the outer edge of the left reinforcing part 9 and the left body 1A.

Still distribute a plurality of joint sleeves 10 in the left recess 6 of left side body 1A, joint sleeve 10 constitutes integral structure with left body 1A, just joint sleeve 10 is the tubular structure who comprises a plurality of stand jack catchs 18, and a plurality of stand jack catchs 18 form the joint face inside the tubular structure who encloses.

The edge glue injection groove 8 is formed in the end face of the edge connecting protrusion 7 in the downward direction, and the distribution path of the edge glue injection groove 8 along the outer edge of the left body 1A is the same as the path of the edge connecting protrusion 7.

The end surfaces of the edge connecting bulge 7, the clamping sleeve 10 and the left reinforcing part 9 are the same in height relative to the bottom surface of the left groove 6.

The shape of the right body 1B is matched with that of the left body 1A, and the two are buckled and bonded to form the body 1.
