Description
技术领域
[0001]本实用新型涉及试验装置技术领域，特别是涉及一种液体试剂滴定装置。
背景技术
[0002]采用连续流动分析仪检测烤后千烟叶片中的淀粉含量时，烟叶样品中需要缓慢一 滴一滴的加入总量为1.2ml的高氯酸，并且不停的搅拌，长期以来实验员都是通过滴管手动 滴加，每次只能向一个样品中滴加高氯酸，并且由于每个人滴加的速度不同，即使同一人在 滴加试剂过程中因产生疲劳，也会导致滴加速度前后不同，从而影响检测的准确性，此时需 要一种能均匀控制滴加速度的装置。 实用新型内容
[0003] 本实用新型的目的是提供一种液体试剂恒量滴加装置，以解决上述现有技术存在 的问题，一次能向多个样品中恒量稳定地滴加试剂，使每个样品中的试剂滴加速度相同，大 大减少误差，提高检测效率和准确性。
[0004] 为实现上述目的，本实用新型提供了如下方案:本实用新型提供一种液体试剂恒 量滴加装置，包括支架横臂及若干个液体试剂容器，各所述液体试剂容器的顶部均开口，各 所述液体试剂容器底部均带有一滴管，各所述滴管规格相同，所述若干个液体试剂容器相 互间隔固定于所述支架横臂上。
[0005] 本实用新型液体试剂恒量滴加装置，其中，所述支架横臂上开有若干个通孔，各所 述液体试剂容器分别设置于一个所述通孔内。
[0006] 本实用新型液体试剂恒量滴加装置，其中，所述液体试剂容器为玻璃针筒，所述玻 璃针筒顶部带有凸出玻璃针筒圆周表面的定位片，所述定位片抵靠在所述支架横臂上表 面。
[0007] 本实用新型液体试剂恒量滴加装置，其中，所述滴管为无针针头。
[0008] 本实用新型液体试剂恒量滴加装置，其中，所述支架横臂一端通过连接架设置于 支架立杆上，所述连接架上开有第一容置槽和第二容置槽，所述支架立杆位于所述第一容 置槽内，所述支架横臂位于所述第二容置槽内，所述第一容置槽的槽壁上螺纹连接有用于 固定所述立杆支架的顶杆，所述第二容置槽的槽壁上螺纹连接有用于固定所述支架横臂的 顶杆。
[0009] 本实用新型液体试剂恒量滴加装置，其中，所述支架立杆底部固定有底座。
[0010] 本实用新型相对于现有技术取得了以下技术效果：由于本实用新型液体试剂恒量 滴加装置包括支架横臂及若千个液体试剂容器，各液体试剂容器底部均带有一滴管，各滴 管规格相同，因此使用时在重力作用下液体试剂容器内的试剂会经各滴管以相同的速度滴 下，从而避免因试剂滴入速度不同而使反应速度不同，影响检测的准确性，并且由于液体试 剂容器设置多个，可同时向多个样品中滴加试剂，提高工作效率。
附图说明
[0011] 为了更清楚地说明本实用新型实施例或现有技术中的技术方案，下面将对实施例 中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本实用新型的 一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据 这些附图获得其他的附图。

[0013] 图2为本实用新型液体试剂恒量滴加装置的俯视图；
[0014] 图3为本实用新型液体试剂恒量滴加装置的左视图。
[0015] 附图标记说明：支架横臂11、玻璃针筒12、定位片121、无针针头13、支架立杆14、底 座141、连接架15、第一顶杆16、第二顶杆17。
具体实施方式
[0016] 下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行 清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的 实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下 所获得的所有其他实施例，都属于本实用新型保护的范围。
[0017] 如图1、2、3所示，本实用新型提供一种液体试剂恒量滴加装置，包括支架横臂11及 十个液体试剂容器，各液体试剂容器的顶部均开口，各液体试剂容器底部均带有一滴管，支 架横臂11上相互间隔开有若干个通孔，各液体试剂容器分别固定于一个通孔内，液体试剂 容器还可设置少于十个或多于十个。
[0018] 进一步，为使本装置结构更简单、更便于取材，如图1、2、3所示，液体试剂容器采用 顶部敞口的玻璃针筒12,滴管采用无针针头13,各无针针头13的规格相同，玻璃针筒I 2顶部 带有凸出玻璃针筒12圆周表面的定位片121，玻璃针筒12放置在通孔内后定位片121抵靠在 支架横臂11上表面，使玻璃针筒12的位置固定。
[0019] 实际使用本实用新型液体试剂恒量滴加装置向烟叶样品中滴入高氯酸时，将多个 烟叶样品分别放置于一个玻璃针筒12下方，用移液枪向每个玻璃针筒12中都加入1. 2ml高 氯酸，在地球引力的作用下高氯酸经多个无针针头13分别滴入多个烟叶样品中。
[0020] 如图2所示，支架横臂11 一端通过连接架15设置于支架立杆14上，连接架15上开有 第一容置槽和第二容置槽，支架立杆14位于第一容置槽内，支架横臂11位于第二容置槽内， 第一容置槽的槽壁上螺纹连接有用于固定立杆支架14的第一顶杆16,第二容置槽的槽壁上 螺纹连接有用于固定支架横臂11的第二顶杆17,支架立杆14底部固定有底座141。通过连接 架15可调整支架横臂11的高度。
[0021] 本实用新型中应用了具体个例对本实用新型的原理及实施方式进行了阐述，以上 实施例的说明只是用于帮助理解本实用新型的方法及其核心思想；同时，对于本领域的一 般技术人员，依据本实用新型的思想，在具体实施方式及应用范围上均会有改变之处。综上 所述，本说明书内容不应理解为对本实用新型的限制。
