Description

用于药品检验分析的滴定调速装置
技术领域
本发明涉及一种用于药品检验分析的滴定调速装置。
背景技术
药品检测时候有时候需要借助滴定分析仪，但是现在所使用的仪器结构复杂，控制和操作不方便，不能够方便的调整滴速。
发明内容
为克服现有技术的缺陷，本发明提供一种用于药品检验分析的滴定调速装置，本发明的技术方案是：
用于药品检验分析的滴定调速装置，包括底座、立柱和顶板，所述的立柱安装在底座和顶板之间的一侧，所述的顶板上安装有滴管，在所述的滴管内安装有调速机构，该调速机构通过安装在立柱上的气缸驱动，该气缸的伸缩杆上安装有套筒，套筒的另一端沿滴管的径向伸入至滴管内，所述的伸缩杆滑动的安装在导轨上，该导轨通过安装在底座上的支撑杆支撑，所述的调速机构包括弹性带，所述的弹性带为数个，沿圆周方向围成一封闭的球体，每一弹性带的两个端部安装在滴管的内壁上，中间部分向外突出，所述的套筒与弹性带滑动配合。本发明的优点是：能够方便的调整滴液速度，操作简单，使用方便，易于控制。
附图说明
图1是本发明的主体结构示意图。
具体实施方式
下面结合具体实施例来进一步描述本发明，本发明的优点和特点将会随着描述而更为清楚。但这些实施例仅是范例性的，并不对本发明的范围构成任何限制。本领域技术人员应该理解的是，在不偏离本发明的精神和范围下可以对本发明技术方案的细节和形式进行修改或替换，但这些修改和替换均落入本发明的保护范围内。
参见图1，本发明涉及一种用于药品检验分析的滴定调速装置，包括底座1、立柱3和顶板2，所述的立柱3安装在底座1和顶板2之间的一侧，所述的顶板2上安装有滴管8，在所述的滴管8内安装有调速机构，该调速机构通过安装在立柱3上的气缸4驱动，该气缸4的伸缩杆7上安装有套筒9，套筒9的另一端沿滴管的径向伸入至滴管8内，所述的伸缩杆7滑动的安装在导轨6上，该导轨6通过安装在底座1上的支撑杆3支撑，所述的调速机构包括弹性带10，所述的弹性带10为数个，沿圆周方向围成一封闭的球体，每一弹性带10的两个端部安装在滴管8的内壁上，中间部分向外突出，所述的套筒9与弹性带10滑动配合。
本发明的工作原理是：通过气缸的驱动，伸缩杆沿导轨前移，此时套筒将把所有弹性片罩入其内，弹性带的膨胀面积缩小，进而缩小了对滴液的阻挡面积，增加了液体流速。当需要减小液体流速时，气缸伸缩杆缩回，弹性带膨胀，增大了对滴液的阻挡面积，减少了液体流速。
