具体实施方式
帽盖20带有锁紧机构24，其用于使帽盖20可选择地进入到锁紧状态和非锁紧状态，其中在锁紧状态，帽盖20禁止从开口28上取下，而在非锁紧状态，则可以将帽盖20从开口上28上取下。在一实施例中，使用帽盖20来闭合开口28，所述开口属于油罐(未示出)填料管32的一部分。在锁紧的状态下，帽盖20不容易受到包括偷窃帽盖20和/或罐子中容纳物之类的破坏。
如图1-3和图7所示，帽盖20包括一外盖部分36(或称为“盖”)，操作者可抓紧外盖使帽盖20相对于开口28围绕轴A转动。帽盖20还包括一内螺纹部40。内螺纹部40是一形成有螺纹41的实体或部件，这些螺纹与开口28上形成的互补螺纹啮合。密封件48设置在盖36和内螺纹部40之间，垫圈52设置在用于接合开口28的内螺纹部40下面。在一些结构中，密封件48为毛毡防尘密封，该毛毡防尘密封不必是气密的。
盖36和内螺纹部40通过锁紧机构24彼此可选择地接合在一起。通常，选择性地操作锁紧机构24，使帽盖20处于不能从开口28上取下的状态。锁紧机构还能够可选择使将罩36和内螺纹部40之间的旋转传动连接断开，这样，盖36围绕轴A的扭矩不会传递给内螺纹部40，并且盖36的转动也不会导致内螺纹部40产生转动。在非锁紧状态下，为了传递扭距，锁紧机构24连接罩36和内螺纹部40，以允许把帽盖20从开口28上取下和/或安装到开口28上。锁紧机构24不需要罐子或开口28作出改变，它可以与包括标准尺寸在内的各种尺寸的帽盖和螺纹匹配。
锁紧机构24包括锁紧柱组件56(在一些结构中，是现成的锁紧柱)，该锁紧柱组件容纳在盖36的孔58内，由保持夹59对其进行定位。锁紧柱组件56包括凸轮部60，所述凸轮部可相对于盖36和锁紧柱组件56的保持件在第一位置(参见图4)和第二位置(参见图5)之间移动。在图示的实施例中，凸轮部60围绕轴A旋转。可将一键合件(未示出)插入到锁紧柱组件56中，对其操作从而使凸轮部60在第一位置和第二位置之间枢转。锁紧机构24还包括与盖36连接的滑块64。滑块64支撑在盖36上，从而能够随着盖36围绕轴A的转动而旋转，并且能够相对于盖36可选择地滑动。在图示的实施例中，滑块64被支撑着，沿盖36的径向即基本垂直于轴A的方向滑动。
滑块64带有第一和第二导向突起64A，所述导向突起从滑块64向盖36的横向壁65处伸出。横向壁65带有一对导向狭槽65A，用以接收导向突起64A，并允许滑块64在基本垂直于轴A的方向上相对于盖36仅沿着一条短径运动。滑块64还带有一凸轮从动面66，该凸轮从动面66同凸轮部60接触，使滑块64能够沿着短径移动，以下将对此进一步详细说明。
锁紧机构24还包括诸如被支撑着与内螺纹部40一同转动的护圈68结构。例如，可以将护圈68焊接、粘结或扣合到内螺纹部40。在一些实施例中，护圈68成形为与内螺纹部40分离的单独部件，将其永久地连接于(如通过旋转焊接)内螺纹部40，这样就可以把护圈68当作内螺纹部40的一部分。滑块64和护圈68分别包括齿状物组72和76，所述齿状物可选择地将滑块64和护圈68彼此连接起来，借此将盖36连接于内螺纹部40。
在非锁紧的状态下(参见图4)，锁紧柱组件56的凸轮部60移动到第一位置，这样就将滑块64推动到伸出的位置并与护圈68接合在一起，从而滑块上的一组或多组齿72与护圈上的一组或多组齿76接合在一起。由于滑块64和护圈68彼此接合固定而抵制了它们之间的转动，因此操作者可以抓紧盖36使之旋转(如以逆时针方向)，从而旋出帽盖20并将其从填料管32取下。此外，操作者也可以抓紧盖36使之旋转(如以顺时针方向)，从而旋紧帽盖20并将其安装到填料管32上。
在锁紧状态下(参见图5)，锁紧柱组件56的凸轮部60移动到第二位置，这样就使滑块64保持在缩进的位置并断开与护圈68的连接，从而滑块上的齿72与护圈上的齿76脱离。在该实施例中，滑块上的齿72被阻止同护圈上的齿76接合，盖36可以相对内螺纹部40自由转动而不会向其传递扭矩或旋转运动。因此，当破坏者试图在锁紧的结构下旋出帽盖20时，盖36会转动，但不会把扭矩传递给护圈68或内螺纹部40，因此不能将帽盖20从填料管32上旋出。
应当理解的是，在另外的结构中，锁紧机构24可以包括不同的部件和/或具有能够以不同方式操作的部件。例如，凸轮部60可以以不同的方式(如侧至侧侧向地、上下竖直地之类的滑动，竖直地枢转等)在第一和第二位置之间移动。此外，滑块64还可以以不同的方式(如在伸长和缩进位置之间枢转，而不是沿着轴线滑动)在伸长位置和缩进位置之间移动以及沿着不同的轴线滑动(如上和下)。
此外，可以提供各种结构使盖36与内螺纹部40旋转连接。例如，可以在盖36和内螺纹部40之间提供摩擦接合(而不是齿啮合)。在一些结构中，帽盖20包括不同类型的齿啮合，如用以防止帽盖20被过紧地固定在填料管32上的棘齿组件，这种棘齿组件可以防止对帽盖20和/或填料管32造成损害，并且向使用者提供了听觉上和/或触觉上的反馈，以告知使用者已经达到了足够等级的扭矩(如达到或大于最小保持扭矩)等。棘齿组件包括在盖36和内螺纹部40之间形成棘齿啮合的组件。在这种结构中，滑块64被构造成能够与内螺纹部40形成棘齿啮合。例如，滑块64可以具有一个或多个柔性接合件，用以在帽盖20处于非锁紧状态下沿帽盖安装方向与内螺纹部40形成棘齿啮合。不管是否提供了棘齿作用，在可选的实施例中，帽盖20中的齿啮合可以具有不同的定位、数量和齿形72，76。
在一些实施例中，如图2，4和5所示，滑块64包括两个肋84，这两个肋与滑块成为一整体，并且从滑块64表面88向外凸出。肋84沿着面向着盖36的方向从平坦表面88伸出。肋84被构造成当滑块64从锁紧位置移动到非锁紧位置以及从非锁紧位置移动到锁紧位置时，能够扣合到盖36内部相应的肋92上。这就在锁紧的/非锁紧的帽盖20发生变化(即当滑块64从缩进位置移动到伸出位置，或反之)时，向使用者提供了触觉和/或听觉上的反馈。在一些实施例中，滑块64上的肋84和盖36上相应的肋92明确地将滑块64定位在锁紧位置或非锁紧位置上，并且还可以防止滑块64偶然运动离开所要求的位置。
如图1-3和7所示，在一些实施例中，防尘罩95被可转动地安装在盖36上，用以保护锁紧机构24不受到粗粒条件和碎屑。防尘罩95包括图示的实施例中可看到的标记98，其用以表示防尘罩95从密闭位置到打开位置的转动方向。
在一些实施例中，最好如图7所示，盖36包括邻近锁紧机构的可看到的标记102，其用以表示键合件的转动方向，以便实现锁紧操作和相对的解锁操作。在图示的实施例中，标记102包括一“锁紧”的挂锁符号，一“解锁”的挂锁符号和相应的弯箭头。
至少在图8-14中示出了根据第二实施例的帽盖200及其单独的部分。帽盖200围绕轴A’转动，并可选择地与开口28接合。帽盖200包括一些与图1-7所示的帽盖20共有的特征，这些特征用同样的附图标记表示。这里将详细说明不同于第一实施例的元件和特征。帽盖200包括外盖部分204(或简单称作“盖”)和连接于盖204用以转动的滑块208。滑块208包括四个凹口212，它们分别与盖204的横向壁220内表面上的杆件216接合。滑块208还包括齿224，用于与帽盖200的内螺纹部232上互补的齿228啮合。滑块的齿224间隔地围绕在滑块208外围的周围。在图示的实施例中，滑块208通常为圆形并且带有一凸缘236部。凹口212和齿224从凸缘部236径向伸出。在图示的实施例中，每个齿224在圆周上间隔在一对相邻的凹口212之间，反之亦然。滑块的每个齿224都形成在棘齿件240的远端。
滑块208包括形成在中心孔252内壁250上的螺纹248。帽盖200还包括锁紧机构256，该锁紧机构带有一锁紧柱组件260和一致动件264。在一些实施例中，锁紧柱组件260与图2-5和7所示的锁紧柱组件56基本相同，其被容纳在盖204的开口262中。致动件264带有用以同滑块208的螺纹248相接合的螺纹268。锁紧柱组件260包括可与致动件264接合的凸轮部272。在一些实施例中，凸轮部272和致动件264彼此恒定地传动接合在一起，以便在锁紧柱组件260由键合件(未示出)制动时，致动件264的转动量基本等同于凸轮部272围绕轴A’的转动量。在图示的实施例中，凸轮部272容纳在致动件264的凹陷处276，并且凸轮部272和致动件264围绕轴A’的转动比为1∶1。
当致动件264在凸轮部272的带动下转动时，致动件驱使滑块208沿平行于轴A’的方向移动。滑块208经由凹口212和杆216受到固定不能相对于盖204转动。因此，致动件264的转动驱使滑块208沿轴A’与内螺纹部232上的齿228接合和脱离。
当滑块的齿224与内螺纹部232的齿228啮合时，帽盖200处于非锁紧状态，可以使盖204沿逆时针方向围绕轴A’转动，从而将帽盖200从开口28上取下。经由滑块的齿224和内螺纹部232的齿228，在盖204和内螺纹部232之间沿取下帽盖的方向形成了传动连接。当帽盖200处于非锁紧状态时，盖204沿顺时针方向(安装帽盖的方向)在开口上208转动，在盖204和内螺纹部232之间形成了扭矩限制的传动连接。当沿安装帽盖的方向向盖204施加的扭矩超过预定值时，滑块208的棘齿件240径向向内偏斜以允许棘齿件远端的齿224滑过内螺纹部232的齿228。
当滑块的齿224与内螺纹部232的齿228脱离时，帽盖200处于锁紧状态，并且在盖204和内螺纹部232之间的任一方向上都没有传动连接。因此，不能通过沿帽盖取下方向围绕轴A’的转动把帽盖200从开口28上取下。
这里公开的对帽盖附加的改进包括设置系绳把帽盖20或200保持在填料管，或诸如车架或车体之类的其它部件上。不同长度和结构的系绳都可以提供给帽盖20和200。帽盖20或200可以带有排气孔或不带排气孔，可以具有外螺纹或内螺纹，并且还可以具有不同尺寸和类型的螺纹。
