本发明涉及一种样品架。
背景技术
在进行环氧乙烷残留量检测时，样品需要在25℃或37℃的环境下进行浸提，浸提完成后放到冰箱进行平衡，将浸提出的环氧乙烷予以液化。由于环氧乙烷在10℃-15℃左右便会汽化，在样品制备过程中，样品瓶内浸提液的温度无法监控，会对检测结果的准确性产生影响。

具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
此外，下面所描述的本发明不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
如图1所示，样品架包括架子组件1和底座组件2。
其中，架子组件1包括一个横板3，横板3上设置有多个插孔4。插孔4用于插置样品管(图中未示出，类似化学领域的试管)。横板3两侧设置有侧板16，侧板16为架子组件1的一部分，侧板16将横板3与底座组件2相连接。
底座组件2包括一个底板5，底板5位于横板3的下方，底板5中设置有多个凹槽6。凹槽6与横板3中的插孔4相对应，凹槽6用于承托样品管的底部。
凹槽6底壁开设有容纳孔9，容纳孔9中插置有温度探头7。温度探头7用于测量样品管的温度，即测量样品的温度。
底座组件2还包括显示屏8，显示屏8与对应的温度探头7相连接，用于显示温度探头7所测量的温度大小。
因此，只要样品管放在凹槽6中，通过开关开启温度探头7以及显示屏8(打开开关也即供电)，便可以实时显示样品管的温度，方便检验员在浸提操作时判定检测时机。
本例中，温度探头7设置在凹槽6的底部，这是一种优选的方案，方便于温度探头7与样品管充分接触，因为由于重力作用样品管会紧压温度探头7。更为优选的，温度探头7设置在凹槽6底部中心位置，进一步使温度探头7与样品管充分接触，因为样品管的底部多为球面形。其它实施方式中，还可以将温度探头7设置在凹槽6的侧壁。
本例中，凹槽6底壁开设有容纳孔9，温度探头7插置在容纳孔9中，这也是一种优选的方案，便于固定温度探头7。且温度探头7由于埋入容纳孔9中而被隐藏，温度探头7不会占据凹槽6的空间，这样不仅使样品管能更平稳地放置在凹槽6中，而且可以避免温度探头7将样品管挤坏。本例中，温度探头7的顶端大致与凹槽6的底面相齐平。
如图2，图2为图1中A-A剖视图，底座组件2还包括空腔10，空腔10设置在底板5下方。空腔10的一个作用是用于容纳温度探头7。
空腔10中还设置有探头固定板11，探头固定板11可通过胶水或其它常规方式固定在空腔10中。探头固定板11约中部开设有固定孔12，温度探头7插置在固定孔12中。温度探头7外周设置有外螺纹13，外螺纹13上螺拧有两个紧固螺母14，探头固定板11被夹持在两个紧固螺母14之间，从而将温度探头7固定到探头固定板11上。
设置探头固定板11的作用是为了将温度探头7固定，且方便于安装。其它实施方式中，还可以不设置探头固定板11，比如将温度探头7螺拧在容纳孔9中(在温度探头7外周设置螺纹，在容纳孔9内壁设置与温度探头7外周螺纹相匹配的螺纹)。
在温度探头7外周设置外螺纹13以及设置紧固螺母14也是一种优选的方式，主要是方便于安装和拆卸温度探头7。其它实施方式中，还可以将固定孔12制作得等于或略小于温度探头7的外径，将温度探头7紧插在固定孔12中而被固定。
如图2，本例中，温度探头7和显示屏8均由电池15供电，为了使样品架更迷你，将电池15也设置在空腔10中。电池15与显示屏8相连接，电池15与温度探头7之间通过显示屏8(显示屏8中集成有电源开关)间接相连接。
为了使样品架更迷你，还将显示屏8的至少一部分镶嵌在空腔10中。
为了更好地稳固温度探头7，将空腔10中的部件位置进行优化：探头固定板11相对于电池15更靠近底板5，这样探头固定板11与底板5之间的距离较小，有利于通过探头固定板11将温度探头7更为平稳地稳固在凹槽6底部。
综上所述，本例的样品架，将样品管底端放置在凹槽6中，通过凹槽6中 温度探头7测量样品管温度，通过显示屏8实时显示测得温度，方便检验员在浸提操作时判定检测时机。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围，凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
