如图6所示，沿轮圈1的外圈依次设有若干通孔二11，在轮圈1的内圈与通孔二11对应的位置上依次设有若干通孔三12，通孔二11与通孔三12相互贯穿，通孔二11与通孔三12用于使辐条帽2从轮圈1外圈插入并露出于内圈，通孔二11的直径大于通孔三12的直径，通孔二11的直径稍大于辐条帽沿22的直径尺寸，用于使辐条帽2的辐条帽沿22穿过，通孔三12的直径稍大于辐条帽杆21的直径，且通孔三12的孔径小于辐条帽沿的外径，用于使辐条帽2的辐条帽杆21插入，辐条帽2插入轮圈1后，辐条帽2的辐条帽沿22抵靠在轮圈1下部的内侧壁上，辐条帽2的辐条帽杆21和固定螺杆23露出于通孔三12，用于固定连接辐条5。
如图1和图7所示，辐条帽2通过辐条帽固定螺母3固定在轮圈1上时，辐条帽固定螺母3与轮圈1之间还设有垫片4，垫片4为矩形形状，垫片4接触轮圈1内圈的一面设有弧形槽41，垫片4中心位置设有通孔四42，通孔四42用于使辐条帽2插入。垫片4用于避免辐条帽固定螺母3与轮圈1的接触面不够以及适应不同车轮的辐条不同角度的设置。
如图1和图8所示，辐条5的辐条主体52为碳纤维复合材料，辐条5的辐条主体52两端连接有辐条连接件一51，辐条连接件一51为金属材质，辐条连接件一51的端部设有螺纹，用于和辐条帽2的通孔一24内的螺纹螺接固定以及和花鼓法兰6连接。在本实施例中，辐条5的辐条主体52和辐条连接件一51之间的连接方式可采用胶结固定的方式，在其它实施例中，辐条5的辐条主体52和辐条连接件一51之间的连接方式可采用拉铆的方式，辐条5的辐条主体52也可以采用其它材质，例如钛合金或高碳钢材质。
如图1和图9所示，辐条5一端连接有花鼓法兰6，花鼓法兰6整体呈花鼓造型，花鼓法兰6由花鼓壳本体61、轴承端盖62和轴承组成，轴承端盖62设置在花鼓壳本体61的两端中心位置，轴承安装在轴承端盖62的内部，轴承端盖62与轴承可拆卸的连接，花鼓壳本体61两端具有圆弧形凸起部，圆弧形凸起部上设有若干通孔五63，通孔五63为螺纹孔，用于和辐条5的辐条连接件一51固定连接。
使用时，自行车在行驶时，车轮的轮圈1外包裹着轮胎,在行驶过程中车轮载重与地面接触，产生的压力通过轮胎传递给轮圈1，辐条5通过辐条帽2和花鼓法兰6固定在轮圈1内为轮圈1提供支撑，因为载重，车轮下方的辐条因为受到轮圈自身的拉力降低，受到了来自地面和载重的压力，辐条一端连接的辐条帽发生移动，导致下方辐条的长度缩短，花鼓法兰的轴心位置会发生移动，上方辐条因为受到较大拉力，辐条一端连接的辐条帽发生移动，辐条相应拉长。但是辐条帽2上安装连接有辐条帽固定螺母3，辐条帽固定螺母3将辐条帽2牢固的固定在轮圈1上，使辐条和轮圈具有一体性。在下方辐条因为受到拉力降低要产生缩短的时候，因为辐条帽固定螺母抵靠轮圈内圈壁上，为辐条提供向上的支撑力，使辐条无法产生缩短，进而上方的辐条也不会产生拉长，保证了自行车在骑行过程中，轮圈不会容易发生变形。
实施例 2。
实施例2提供的一种自行车辐条固定结构与实施例1提供的一种自行车辐条固定结构基本相同，其不同之处在于辐条的结构不同。
如图10所示，辐条5与花鼓法兰6的连接方式可以根据辐条的设计采用不同的方案，辐条5的辐条主体52只有一端连接有辐条连接件一51，辐条5的辐条主体52采用一体式碳纤维的材质，碳纤维的辐条5另一端可设为楔形膨大头53，辐条5的楔形膨大头53与花鼓法兰6相连接，花鼓法兰6与辐条5的楔形膨大头53的连接处可以根据辐条端部形状相应作出改变。
实施例 3。
实施例3提供的一种自行车辐条固定结构与实施例1提供的一种自行车辐条固定结构大致相同，其不同之处在于辐条与辐条帽的结构不同。
如图11所示,辐条5包括辐条主体52、和辐条主体52一端连接的辐条连接件二55,辐条主体52为碳纤维材质，辐条主体52为扁条形，辐条连接件二55为金属材质，辐条5的辐条主体52和辐条连接件二55之间的连接方式可采用胶结固定的方式或者拉铆的方式，辐条连接件二55与辐条帽2连接的一端设有连接孔54，连接孔54设有内螺纹，用于连接辐条帽2，辐条5的另一端与花鼓法兰6连接，辐条5另一端与花鼓法兰6的连接方式可以采用实施例1或者实施例2的连接方式。
如图12所示, 辐条帽2包括相连接的辐条帽杆21、辐条帽沿22、用于扳手旋拧的固定螺杆23、辐条连接杆25，辐条帽沿22的直径尺寸大于辐条帽杆21的直径，所述辐条帽杆21设有用于连接辐条帽固定螺母3的外螺纹，固定螺杆23的一端与辐条帽杆21相连接，固定螺杆23的另一端与辐条连接杆25相连接，所述辐条连接杆25与辐条5连接的端部设有外螺纹，辐条帽2采用金属材质。
实施例 4。
本发明的实施例4提供一种自行车辐条固定结构，包括第一固定件2a、第二固定件3a和辐条4a，辐条4a一端设有辐条连接件41a，辐条连接件41a穿过轮圈1a内圈上的通孔二11a后与第一固定件2a、第二固定件3a分别从轮圈1a内圈的内侧和外侧固定，辐条4a另一端连接花鼓法兰。
作为本发明的一种实施方式，第一固定件2a、第二固定件3a可以是具有螺纹连接功效的各种结构。进一步，第一固定件2a、第二固定件3a可以是样式相同或不同的螺母，螺母样式可以是顶部带凸沿或不带凸沿的螺母，也可以是带垫圈的螺母。螺母的形状可以是外六角形或其他形状。
作为本发明的一种实施方式，如图14所示，第一固定件2a包括螺母本体21a和凸沿22a，凸沿22a从螺母本体21a的底面向外凸出，螺母本体21a和凸沿22a可以是一体成型。螺母本体21a可以设置外六角形结构用于扳手旋拧使第一螺母2a与辐条4a旋紧或松开。辐条连接件41a可以是设置在辐条4a一端的外螺纹。螺母本体21a中心位置设有贯穿的通孔一23a，通孔一23a设有内螺纹用于与辐条连接件41a的外螺纹螺接。第二固定件3a的结构可以与第一固定件2a相同或不同。图14所示的第二固定件3a的结构与第一固定件2a相同。装配时，辐条连接件41a依次穿过第二固定件3a、通孔二11a、第一固定件2a，而后使用扳手将第一固定件2a和第二固定件3a旋紧使第一固定件2a的下表面紧贴轮圈1a内圈的内侧，第二固定件3a的下表面紧贴轮圈1a内圈的外侧。图14中，轮圈1a为图1中轮圈1的横截面。常规的自行车辐条固定结构只在轮圈1a内圈的内侧设置螺母或辐条帽，使用该方法编制的车轮中辐条4a只能提供拉力。在本实施例中，第一固定件2a、第二固定件3a分别从轮圈1a内圈的内侧和外侧与辐条4a固定，使辐条不仅能提供拉力还可以提供支撑力，提升了车轮整体结构的稳定性。
以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭示如上，然而并非用以限定本发明，任何本领域技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
