Description

带有滑座和可调冲头的冲孔器
本申请为中国专利申请号96191196.4的分案申请。
技术领域
本发明涉及一种带有滑座和可调冲头的冲孔器。
背景技术
带有抽出式滑座的冲孔器是已知的。具有可调冲头位置的滑座式冲孔器也是已知的，但是要求拆掉滑座进行调整。
发明内容
概括地说，本发明是一个滑座式可调的手动冲孔器，无须拆掉滑座从冲孔器的底部便可完成调整。压板手柄用来增力。
本发明提出一台手动冲孔器包括：a)一个具有一个上部平坦表面的手柄；b)一个销轴，用于可枢转地安装该手柄于一个基座，以绕该销轴的一个纵向轴线作转动；c)该手柄还具有：i)一个设置在与该上部平坦表面成90度的远处折边端部，该远处折边端在一个与该销轴分隔的一侧上与该纵向轴线平行延伸；ii)一个设置在与该上部平坦表面成90度的近处垂直折边部，该近处垂直折边部在该销轴分隔的该一侧相反的侧上与该纵向轴线平行延伸并从该冲孔器的一个第一端延伸到该冲孔器的一个第二端；和d)该近处垂直折边部在上部平坦表面之下的位置端接于一个反向卷边部，该反向卷边部限定设置在该上部平坦表面之下的直立唇状部。
本发明还在于，a)该手柄具有一个总长度；和b)该反向卷边部具有小于该手柄总长度的卷边长度并从邻近该冲孔器第一端的一个第一点延伸到邻近该冲孔器第二端的一个第二点。
此外，还包括：一个设置在远处折边端部和近处垂直折边部之间并与该纵向轴线分隔开的手柄凹坑限定的冲孔器接合区，以在手柄绕该纵向轴线枢轴转动时，与滑动安装在手柄之下的冲孔销接合来使这些冲孔销穿过将要冲孔的材料。
还包括滑动安装在手柄之下并设置在远处折边端部和近处垂直折边部之间的冲孔销，这些冲孔销与该纵向轴线分隔开，以在手柄绕该纵向轴线枢轴转动时，使这些冲孔销穿过将要冲孔的材料。

图6是装上滑座的冲孔器的单独的底部透视图；
图7是基座的顶部透视图，滑座伸出来排空；
图8是滑座的顶透视图；
图9是压板手柄的顶视图；和
图10是从反向卷边边缘所视的手柄的正视图。
具体实施方式
在图1至图4中，冲孔器10包括基座11，端部支承板12a，12b，上部为平坦表面13的手柄14，设置为绕支承板12a，12b上的销轴16a，16b转动的手柄凹坑13a，13b，13c。杠杆17可枢转地安装在支架18a，18b上。还示出了冲孔组件头21a，21b，21c和装在基座导轨板11a，11b上的滑座23。组件头21a-c包括槽部卷边凸出34a-c，这些卷边伸进槽40内以防止组件头21a-c移动时产生转动(参照图7)。
具体参考图2，手柄14由金属板材制成并包括大体垂直于平坦表面13的远处折边端14a(远离销轴16b)；远处平坦部14b，凹坑部13a，近处平坦部14c；垂直于平坦表面13和反向卷边部15的近处垂直折边部14d。反向卷边部15的作用是增强和加强手柄14并包括弧形部15a和直立唇状部15b。
手柄14的金属板材厚度为T。下面的表1给出了手柄14各部相对厚度T的比例范围。
表1
  部位   尺寸   范围
  1.近处折边2.卷边宽度   ab   6T-8T2.5T-4T
  3.卷边深度4.近处折边加卷边深度   cd   2.5T-4T9T-11T
参考图4-8，可以看到，冲孔组件头21a，21b和21c可以用紧定螺丝26a，26b和26c来调整，这些紧定螺丝可以在调整槽27，28(图5)中运动，而组件头的槽部卷边凸出34a-c在纵向基座槽40中运动。槽40是基座上表面11U之下的一纵向区域并且是一较低基座表面111。槽部卷边凸出34a-c延伸超过基座表面11u到其下面，表面11u允许卷边凸出34a-c在组件头调整期间在槽40内来回移动，并同时防止组件头21a-c在松开期间发生转动，移动组件头是为了调整冲孔间距和组件头的再紧固。如果组件头21a-c谋略转动，它的卷边凸出34a-c将咬住基座边缘11e来防止这种转动。卷边凸出34a-c可以是其它形状的，但最好是弯曲的翻卷形状。调整螺丝以螺纹拧入机壳螺纹孔31a、31b和31c中(图4)。冲孔销P示于图4。基座底面11c示于图5。滑座23有一个中部槽29，使得无须拆除滑座23便可调整螺丝26a-c。
图7示出滑座23滑开用来倒空，并进而示出基座导轨板11a，11b，支承板12a，12b，调整槽27，28和调整螺丝26a-c以及槽40。
在图8中，滑座中部槽29由具有端部29a，29b的围环36围护起来，比围环36的高度36h几乎抵靠基座底面11c以防止纸屑通过中部槽28漏出或跑出。还示出了滑座折边23a，23b和滑座开槽端23c，以及滑座封闭端23d。槽缝37a，37b使得滑座23无须从基座导轨板11a，11b上卸下便可滑开。当滑座23滑开时，围环端部29a接合紧定螺丝26c来限制滑座的移动。中部槽29比外侧调整螺丝26a和26c之间的距离(D)长，以便允许滑座23相对于基座11滑动。中部槽29的长度小于滑座23的总长度，从而当搬动和使用冲孔器10时，全部积存在围环36一侧的冲下的纸屑可以经过围环端部29a，29b转移到另一侧。
最后，在图9和图10中，手柄14的反向卷边部15的长度B小于手柄14的总长度A。最好，从反向卷边部的第一端点51到第二端点52量度的长度B是长度A的至少60％。
