Description

链轮护板
技术领域
本发明涉及一种链轮护板，更特别是涉及一种能够改装的链轮护板，该链轮护板包括共面链轮表面、护板表面和紧固件轴环表面。
背景技术
骑自行车正成为一种越来越流行的娱乐形式和交通方式。多年来广泛地重新设计的领域是自行车传动系。
重新设计的传动系的一个特定部件是前链轮组件。前链轮组件具有在链轮附近的链/辐条保护器，以便防止鞋带和衣服卷入。
通常，现有的链/辐条保护器附接在曲柄轮毂上或者使用轴向卡扣配合而固定在最大链轮上。尽管这些现有的辐条/链保护器总体很好地工作，但是它们通常作为初始部件而被附接。在这些情况下，用于改装护板的可能性很小。还需要能够对现有自行车曲柄进行改装的部件，它相对简单地制造和装配。
考虑到上面所述，本领域技术人员由本公开显然知道有改进自行车链轮护板的需求。
现有技术的代表是美国专利8888629，该美国专利8888629公开了一种自行车链轮组件，它包括链轮元件和链保护器。链轮元件有绕中心旋转轴线布置在外周上的多个齿以及至少一个第一附接元件。链保护器包括保护部分以及布置在该保护部分的径向内侧的附接部分。附接部分有至少一个第二附接元件，该第二附接元件响应于在链轮元件与链保护器之间的相对旋转运动而与第一附接元件匹配。
还需要一种能够改装的链轮护板，该链轮护板包括共面链轮表面、护板表面和紧固件轴环表面。本发明满足了这种需要。
发明内容
本发明的主要方面是提供一种能够改装的链轮护板，该链轮护板包括共面链轮表面、护板表面和紧固件轴环表面。
通过下面对本发明说明和附图，将指出或显然知道本发明的其它方面。
本发明包括一种链轮护板，该链轮护板包括：链轮，该链轮有链轮径向辐条，并有在外周上的齿，该齿布置在平面CL1中，各链轮径向辐条与第一柱形表面连通；圆形部件，该圆形部件有圆形部件径向辐条，各圆形部件径向辐条与第二柱形表面连通；轴环，该轴环有外部柱形表面，紧固件与该轴环接合，第一柱形表面和第二柱形表面与外部柱形表面接合，且都在平面CL2中共面，平面CL1偏离平面CL2。
附图说明
包含在说明书中并构成说明书一部分的附图表示了本发明的优选实施例，并且与说明书一起用于解释本发明的原理。
图1是正视透视图。
图2是后视透视图。
图3是侧视透视图。
图4是曲柄的侧视图。
图5是自行车的侧视图。
具体实施方式
图1是正视透视图。护板10与曲柄链轮的外周配合。曲柄用于自行车上。
护板10是圆形的，并使用与轴环32接合的螺纹紧固件30而安装在链轮20上。垫圈31保证紧固件30在使用时不会松动。
轴环32包括外部柱形表面33。表面33与接收表面21接合。表面21是柱形的，形成在链轮20的两个辐条22a和22b之间。表面21在已知链轮中是典型的。
表面21与表面33接合。各径向辐条22a和22b包括偏移部分22c，该偏移部分22c使得齿23沿旋转轴线A-A沿轴向位移。齿23与带或其它环形部件接合。
护板10包括径向辐条11a和11b。辐条11a和11b的顶点11c包括柱形表面13。表面13与表面33接合。
图2是后视透视图。齿23在与旋转轴线A-A垂直的平面CL1上。护板外环14在与旋转轴线A-A垂直的平面CL2上。平面CL1与平面CL2偏移距离“x”。偏移部分22c使得现有链轮能够通过护板10而改装，而不需要在链轮20中钻安装孔。轴环32、表面13和表面31在平面CL2中共面。轴环32的外边缘与凹口25接合，从而使轴环32相对于链轮20的位置定位。凹口25位于链轮20的内侧并在辐条22a和22b之间，从而提高了安装的装置的美学外观。
图3是侧视透视图。多个紧固件30能够用于将护板安装在现有链轮上。
图4是曲柄的侧视图。曲柄臂40以本领域已知的方式从曲柄的各侧伸出。护板10防止鞋带或裤腿接触链轮或与环形部件缠结。
一种链轮护板包括：链轮，该链轮有链轮径向辐条，并有在外周上的齿，该齿布置在平面CL1中，各链轮径向辐条与第一柱形表面连通；圆形部件，该圆形部件有圆形部件径向辐条，各圆形部件径向辐条与第二柱形表面连通；轴环，该轴环有外部柱形表面，紧固件与该轴环接合，第一柱形表面和第二柱形表面与外部柱形表面在平面CL2中接合，且平面CL1偏离平面CL2。
图5是自行车的侧视图。曲柄70安装在自行车底部托架80上。带B(或链)接合在链轮20和后轮90的轮毂之间。自行车还包括框架F、座椅S、前轮91、手把H，都是本领域已知的。
尽管本文已经介绍了本发明的形式，但是本领域技术人员显然知道，在不脱离本文所述的本发明精神和范围的情况下，可以对部件的构造和关系进行变化。
