Abstract

The utility model relates to an extension rod tail vane for a surfing sailboard, which is manufactured into a U-shaped structure by bending circular pipe-shaped materials. Unilateral holes which can be connected and fixed with the control stick of the sailboard are arranged on the pipe wall of a circular pipe; a plastic element connected with a wind sail is fixed on the outer circumference at the bending part of the U-shaped circular pipe; flat-shaped concave surfaces which are symmetrical are arranged at the bending part of the U-shaped circular pipe; and the plastic element connected with the wind sail is fixed on the concave surface. The utility model overcomes the problem that the strength of a prior aluminum pipe is reduced during the drawing and bending processes; the tabling of the extension rod tail vane and the plastic element is tighter through the concave surface, thereby the volume of the projecting part of the plastic element on the outer circumference of the U-shaped pipe is reduced so that the integrity presents a streamline shape, the damage of prominences to a user is reduced, and the strength of the U-shaped pipe is improved, so that the operation control to the surfing sailboard is more stable and laborsaving.

Description

A kind of surfing windsurfing extension rod tail vane

Technical field

The utility model relates to the surfing windsurfing extension rod tail vane of sailing boat or surfing windsurfing, particularly a kind of structural development.

Background technology

At present, existing surfing windsurfing generally comprises the deck of boat, is fixed with mast on the deck of boat, is fixed with sail and control stalk on the mast, is connected with the U-shaped extension rod tail vane that can regulate extending length at the end of control stalk.Normally circular aluminum pipe of U-shaped extension rod or carbon fiber pipe, have the monolateral hole that many places can be connected with control stalk and fix on the tube wall of U-shaped pipe, be fixed with on the excircle of U-shaped pipe crooked position and sail bonded assembly Plastic Parts, Plastic Parts is provided with and is used for connecting and the fixing rope of sail.In the use of surfing windsurfing, the crooked position of U-shaped pipe is stressed bigger, and is more fragile; The Plastic Parts volume that is fixed on the U-shaped pipe excircle is bigger, and it protrudes the position and may damage the user.

The utility model content

At the deficiency of above existing surfing windsurfing extension rod tail vane, it is higher that the purpose of this utility model provides a kind of intensity, the firm more and labour-saving surfing windsurfing extension rod tail vane of operation control.

The purpose of this utility model is achieved by the following technical solution:

A kind of surfing windsurfing extension rod tail vane, make the U-shaped structure by pipe shape material bending, have the monolateral hole that many places can be connected with the windsurfing control stalk and fix on the tube wall of U-shaped pipe, on the excircle of U-shaped pipe crooked position, be fixed with and sail bonded assembly Plastic Parts, the crooked position of described U-shaped pipe is provided with concave surface, can fix on concave surface and sail bonded assembly Plastic Parts.

As optimal technical scheme of the present utility model, also be provided with internal lining pipe in the pore of described U-shaped pipe U-shaped crooked position.

As optimal technical scheme of the present utility model, described U-shaped pipe is metal tube or carbon fibre tube, and the U-shaped crooked position of metal tube or carbon fibre tube forms symmetrical pancake concave surface through forging and pressing or casting.

The beneficial effects of the utility model are: the crooked position of U-shaped aluminum pipe forms symmetrical pancake concave surface through forging and pressing, overcome the existing aluminum pipe defective that intensity reduces in the stretch bending process, make the chimeric tightr of extension rod tail vane and Plastic Parts by concave surface, reduce Plastic Parts and on U-shaped pipe excircle, protruded the volume at position, the utility model integral body has more streamline contour, reduced the injury that ridge may cause the user, improved the intensity of U-shaped pipe, firm and laborsaving more to the operation control of surfing windsurfing.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

Fig. 1 is the structural representation of the utility model sailing boat;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the structural representation of looking up of Fig. 2.

The specific embodiment

As shown in Figure 1 to Figure 3, a kind of surfing windsurfing extension rod tail vane, after bending, make the U-shaped structure by circular aluminum pipe, be used for the surfing windsurfing, windsurfing comprises the deck of boat 2, be fixed with mast 3 on the deck of boat 2, be fixed with sail 5 and control stalk 4 on the mast 3, be connected with the U-shaped extension rod tail vane 1 that to regulate extending length at the end of control stalk 4.Have the monolateral hole 12 that many places can be connected and fix with windsurfing control stalk 4 on the tube wall of U-shaped extension rod tail vane 1, U-shaped crooked position at U-shaped extension rod tail vane 1 forms symmetrical pancake concave surface 11 after forging and pressing, also be provided with internal lining pipe in the pore of the U-shaped crooked position of U-shaped extension rod tail vane 1.

In the present embodiment, be fixed with on the concave surface of U-shaped extension rod tail vane 1 crooked position and sail 5 bonded assembly Plastic Parts, be equipped with on the Plastic Parts and be used for connecting and the fixing rope of sail.
