Abstract

一个用于驱动带头部的紧固件的工具具有一位于工具上的开口。该开口由工具的一壁所限定。该壁具有一组平面。该组平面在其端部处由一个连接部分而连接在一起来限定该开口。每个连接表面具有与平面平滑连接的凸面。一个凹面与该凸面平滑连接。该凸面和凹面限定了具有相同半径的圆弧。

Description

螺母调整器
本发明涉及一个用于驱动带头部的紧固件的工具，特别是涉及一种套筒型工具或者一个螺母调整器。
当松开或者张紧带头部的紧固件时，希望在不损坏或破坏头部的情况下拆除或张紧该紧固件。通常，紧固件头部是六面的，在本领域中以六边形头部所公知。当紧固一个六边形头部时，在相邻平面侧的顶点附近而非该顶点处施加一个力是非常重要的。这可以防止顶点被弄圆，从而能够用一个螺母调整器或类似工具轻易地旋转该六边形头部。
现有技术中存在着各种用于紧固六边形头部的工具。下面的美国专利显示了各种用于完成六边形头部的紧固或松开而进行的各种设计。这些美国专利限定了圆周定位并在六边形头部施加力的不同表面。这些工具显示在美国专利第4,581,957；5,481,948；4,882,957；5,012,706；5,284,073；5,131,312；4,512,220；5,092,203；4,930,378；4,598,616；4,765,211；5,219,392；和5,388,486中。尽管这些工具看起来似乎可以满足于其预定目标地工作，但发明者仍力争改进该现有技术。
本发明提供了一种工具，它在六边形头部的顶点处设置以间隔。位于平面相交处的工具孔，减少了应力集中，从而减少了一个凹形套筒破裂的可能性。本发明具有一个接触表面，其提供了一个改善的机械优势。本发明提供了的具有一个接触表面的工具使得其可以在旋转的两个方向上施加相等的力。该工具还在离开其顶点处与六边形头部接触，从而减少了弄圆该六边形头部的多边形形状的可能性。
根据本发明的一方面，一个用于驱动带头部的紧固件的工具包括一个位于该工具内的开口。该开口由工具的壁所限定而成。该壁具有一组平面，这些平面通过位于其端部的连接表面彼比连接来限定开口。每个连接表面具有与平面平滑连接的凸形表面。而且，一个凹形表面与该凸形表面相平滑连接。该凹面和凸面限定了具有同样半径的圆弧。凹面相对于工具的中心轴线是对称的。凸面与平面在一切点处相交。而且，凸面与凹面也在一切点处相交。凸面与紧固件头部接触使得接触点是在这样一个角度的位置处，即从对分平面处到工具中心的连线和从接触点到工具中心的连线间的夹角，该夹角大约是十九到二十三度(19°-23°)。此外，凸面和凹面的半径与平行平面间的距离成比例，该半径为该距离的百分之八(8％)。而且，凹面位于中心位于工具的中心处的一个圆上。该圆的直径大约是平行平面间距离的1.178倍。不论紧固件是被松开还是紧固，接触面都在六边形头部施加相等的力。
从下面结合附图和所附权利要求的详细描述，本发明的其他目的和优点对于本领域的技术人员来说将会变得更加清楚明了。
图1是根据本发明的螺母驱动套筒的透视图。
图2是具有根据本发明的套筒的延伸件的侧视图。
图3是套筒在箭头3方向的的平面视图。
图4是图3中位于圆4内的部分放大视图。
图5是本发明的另一实施例的平面视图。
图6是本发明的一附加实施例的平面视图。
参看附图，特别是参看图1，显示了一个螺母驱动套筒并用参考数字10标注。套筒10包括限定一中心孔14的一个壁12。该中心孔14具有一多边形形状，最好是一个六边形，以容纳紧固件的六边形头部16。
中心孔14由一组平面18和连接部分20所限定。各平面18彼此相互定位，使得彼此平行的这些平面间具有一个距离H。距离H限定了给特定套筒适用的头部尺寸。
平面18可以在通过套筒的整个距离上延伸，或者它们也可以终止在沿着套筒的任意处。
连接表面20最好地显示在图4所示的放大图中。连接表面20包括一个凸面22，它平面18和凹面24连续地连接。凹面24与凸面22连续地连接。这样，在相邻的平面处，每个凸面22引导入凹面24。凸面22和凹面24都限定了圆弧。每条圆弧由半径R所限定，凸面和凹面中的半径R是相同的。该半径的尺寸与平行平面间的距离(H)成比例。该比例是半径为0.08H。
凸面22在该凸面的曲面的切点处与平面18结合。类似地，凹面24在该凹面的曲面的切点处与凸面22结合。另外，可以从点划线所画的圆26看到，该凹面沿着一个中心位于工具中心处的圆。该圆26具有1.178倍H的尺寸。这样，外侧区域的圆相切地通过中心在套筒中心处的圆。
工具接触六边形头部的点是沿着凸面的。该接触点位于相对于工具中心有一角度(α)的位置处。作一条从平面18的中点到中心的线L1，再作一条从中心到接触点的线L2，线L1和L2间的该角度在十九到二十三度(19°-23°)之间。接触点的该位置提供了在施加力方面的增加的机械优势。而且，在旋转的两个方向都可在六边形头部施加相等的力。
参看图5和6，本发明显示了一个封闭的盒形端扳手30和封闭端扳手40。可以理解到，平面和连接部分与前面所述的相同，并且用相同的标号表示。
尽管上面详细地描述了本发明的最佳实施例，但是本发明也可以在不脱离所附的权利要求的范围内和等效情况下作出各种改变、变化和变形。
