Description
本发明涉及生物分子实验领域，尤其涉及一种便于调节高度的离心管架。
在生物科学研究领域，离心管已得到十分广泛的应用，在实际的实验室研究与试验中，离心管的使用频率非常高，是一种不可或缺的实验耗材，几乎每个生物化学和分子生物学实验室都要准备多种型号的离心管。
由于一般的离心管都是管状的，不方便直接放置在平台上，因此实验室一般将离心管安放在离心管架上。然而，目前常用的离心管架通常是高度固定的，仅在管架的顶板上开设有供离心管放置的插孔，底板上开设有供离心管从插孔插入后托住底端的锥形孔，这些离心管架一般只适合在某一种特定情形下使用，适用的离心管尺寸规格单一，也不适合在多种场合下使用，导致其具有一定的局限性，例如，一般用于放置规格为1.5ml或者2ml离心管的离心管架不适合用来放入特定液位高度的水浴锅中加热时使用，导致在使用水浴锅加热时都需要将离心管从离心管架上取下，然后将其放置到泡沫浮漂上才能利用水浴锅加热，加热好后再将离心管放回离心管架中，这就造成了水浴操作过程复杂，实验效率低下。
发明内容
鉴于现有技术存在的不足，本发明提供了一种便于调节高度的离心管架，可以克服现有技术中高度固定的离心管架存在的缺陷，该离心管架的高度可以灵活地进行调节，且可以适用于放置更多种规格的离心管，能够满足不同的实验需求。
为了实现上述的目的，本发明采用了如下的技术方案：

实施例1
参阅图1，示出了本实施例的一种便于调节高度的离心管架，主要包括第一面板10、第二面板20以及设于第一面板10与第二面板20之间的长度可调的若干支撑组件30，每个支撑组件30的两端分别与第一面板10、第二面板20连接。第一面板10、第二面板20上均开设有供离心管P自外部插入并穿设的插孔，且第二面板20的至少一个插孔的直径不同于第一面板10上的任何一个插孔的直径。
第一面板10、第二面板20上均可开设有复数个插孔，每个面板上插孔的规格还可以有多个。例如，如图2所示，示出的是第一面板10、第二面板20上均设有不同规格的插孔的情形，第一面板10上开设有一圈围绕其边缘的直径较小的第一插孔101和位于第一插孔101围成的区域内的第二插孔102，与第一插孔101相比，第二插孔102的直径较大。
例如，图2中，第一面板10、第二面板20的表面轮廓呈矩形，第一插孔101呈一圈矩形轮廓排列，第一插孔101的直径为11mm，可用来放置1.5ml和2ml的离心管，横向(第一面板10的长度方向)排列的第一插孔101之间的间距为2mm，纵向(第一面板10的宽度方向)排列的第一插孔101之间的间距为 4mm。第二插孔102的直径为28mm，可用来放50ml的离心管，横向排列的第二插孔102之间的间距为6mm，纵向排列的第二插孔102之间的间距为4mm。横向上，第二插孔102距离临近的第一插孔101的距离为5mm，纵向上，第二插孔102距离临近的第一插孔101的距离为2mm。
与第一面板10相似，第二面板20上开设有一圈围绕其边缘的直径较小的第三插孔201和位于第三插孔201围成的区域内的第四插孔202，与第三插孔201相比，第四插孔202的直径较大。第三插孔201的直径可以与第一插孔101相同，可用来放置1.5ml和2ml的离心管，第四插孔202的直径可以比第二插孔102的直径小，例如，17mm，可用来放置15ml的离心管。
可以理解的是，本实施例的第一面板10、第二面板20的形状并不限于矩形，也可以是圆形、椭圆形等。
第一面板10、第二面板20可以均由医疗级聚丙烯(Polypropylene，即PP)材质制成，可以耐酒精等温和的有机溶剂，工作温度范围为-196℃～121℃，能满足水浴锅的温度需求。
组装完成后，第一面板10上的第一插孔101、第二插孔102分别与下方的第二面板20上的第三插孔201、第四插孔202正对，即，第一面板10上的各插孔的中心与第二面板20上的各插孔的中心完全一致。这样，当第一面板10朝上、第二面板20朝下使用时，中间的第二插孔102可以用于放置50ml的离心管，外围的第一插孔101可以用于放置1.5ml和2ml的离心管，离心管P与塑性的第一面板10过盈配合从而被卡持在对应的插孔内，第一插孔101与下方的第三插孔201正对、第二插孔102与下方的第四插孔202正对，可以在必要时通过调节支撑组件30的工作长度来将对应规格的离心管P的末端抵接在第三插孔201、第四插孔202表面，从而防止离心管发生振荡或摇晃。当第二面板20朝上、第一面板10朝下使用时，中间的第四插孔202可以用于放置15ml的离心管，可以在必要时通过调节支撑组件30的工作长度将15ml的离心管的末端伸入到第二插孔102内防止其横向晃动，外围的第三插孔201可以用于放置1.5ml和2ml的离心管。
此种离心管架既可以利用同一面板放置多种规格的离心管，又可以通过翻转而放置其他规格的离心管，因此，本实施例的离心管架具有更强的兼容性。
本实施例可以在离心管架的四周均安装有支撑组件30，以实现良好的稳定性和操作性。如图3所示，本实施例的支撑组件30具体可以包括相互连接的第 一连接杆31和第二连接杆32以及连接在第一连接杆31和第二连接杆32之间的衔接杆33，第一连接杆31的一端与第二面板20连接，第二连接杆32的一端与第一面板10连接，衔接杆33的两端分别连接第一连接杆31的另一端和第二连接杆32的另一端，以在旋转过程中调节与第一连接杆31和/或第二连接杆32的重合长度。
可以理解的是，本实施例的附图3虽然仅示出了第一连接杆31和第二连接杆32通过衔接杆33相连的情形，本领域的技术人员根据本实施例可以适当增加连接杆的数量，从而使得支撑组件30由更多段结构连接而成，例如，可以在第二连接杆32顶端通过衔接杆33连接另一个第一连接杆31。
这里，第二连接杆32与衔接杆33通过螺纹配合的方式可转动地连接。具体是在第二连接杆32内表面设有内螺纹，衔接杆33朝向第二连接杆32的一端设有外螺纹，内螺纹与外螺纹配合，使得衔接杆33可在旋转过程中伸入第二连接杆32内，并改变伸入长度。
而在衔接杆33的另一端所在侧，本实施例的支撑组件30还具有阻尼环34，阻尼环34沿第一连接杆31的轴向上位置可调地套设于第一连接杆31上，可以在衔接杆33的挤压下与衔接杆33、第一连接杆31过盈配合。阻尼环34为弹性材料，例如，形成为橡胶圈的构造，通过利用材料的阻尼特性，阻尼环34既可以在第一连接杆31上任一调节位置，又可以在衔接杆33的挤压下发生形变，从而被夹紧在衔接杆33与第一连接杆31之间而阻止衔接杆33继续向下运动，从而维持衔接杆33在第一连接杆31上的位置恒定。
当需要调节支撑组件30的工作长度时，只需要旋转衔接杆33，使得衔接杆33脱离阻尼环34，然后通过再次旋转衔接杆33而改变其与第二连接杆32的螺纹配合长度即可实现调节支撑组件30的工作长度的改变，然后再次利用衔接杆33挤压阻尼环34实现固定。此种方式可用于改变衔接杆33与第二连接杆32的组合长度，而本实施例还可以进一步通过调节阻尼环34在第一连接杆31的轴向上的位置来改变衔接杆33与第一连接杆31的组合长度，进一步增大调节范围。
较佳地，第二连接杆32的内径大于衔接杆33的外径，衔接杆33的内径大于第一连接杆31的外径，衔接杆33在旋转过程中具有第二连接杆32套设于第一连接杆31外围的状态。也就是说，当第二连接杆32与衔接杆33的螺纹配合长度较长时，第二连接杆32可以缩短至与第一连接杆31也存在重叠长度，使 得支撑组件30的最短长度可以非常短。为了避免衔接杆33完全进入第二连接杆32内影响操作，衔接杆33上靠近第一连接杆31所在端的外周面上还凸设有限位挡圈330，限位挡圈330的外径大于第二连接杆32的内径，这样，第二连接杆32与衔接杆33的组合长度最短的状态是第二连接杆32的端面抵接限位挡圈330，限位挡圈330可以作为此时的操作部位进行旋转。
在其他实施方式中，第一连接杆31也可以与衔接杆33通过螺纹配合的方式可转动地连接。但是需要注意的是，当衔接杆33的两端分别与第一连接杆31、第二连接杆32螺纹连接时，第一连接杆31、第二连接杆32的螺纹旋向应相反，这样，在衔接杆33旋转过程中，第一连接杆31、第二连接杆32同时朝向或背离衔接杆33运动，从而改变支撑组件30的高度。
实施例2
如图4所示，本实施例与实施例1略有不同，主要在于衔接杆33与第二连接杆32的配合方式不同。
为了实现衔接杆33的旋转操作，本实施例的衔接杆33的与第一连接杆31配合的一端具有内螺纹，第一连接杆31上对应设有外螺纹，衔接杆33与第一连接杆31螺纹配合，在衔接杆33旋转过程中，其与第一连接杆31的螺纹配合长度发生变化。可以理解，也可以设置为衔接杆33上设置外螺纹，第一连接杆31上设置内螺纹，外螺纹与内螺纹配合实现同样的效果。
本实施例中，衔接杆33上靠近第二连接杆32所在端的外周面上凸设有限位柱331，第二连接杆32内中空设置，且沿其轴向上开设有贯穿其一个端面和周面的长孔320、自长孔320的长度方向的多个部位朝周向延伸形成的多个限位孔321。组装时，衔接杆33插设于第二连接杆32内，当衔接杆33在第二连接杆32内轴向移动的过程中，限位柱331可沿长孔320滑动，在衔接杆33相对于第二连接杆32转动的过程中，限位柱331进入对应的限位孔321内，从而可以限制衔接杆33在第二连接杆32内的轴向移动，如此则可以实现衔接杆33与第二连接杆32的组合长度的锁定。当需要调节组合长度时，只需要反向旋转衔接杆33，使限位柱331脱离限位孔321而进入长孔320内，然后调节衔接杆33伸入第二连接杆32的长度至合适位置后，再次旋转衔接杆33，使限位柱331自长孔320卡入另一个限位孔321内实现位置锁定。
进一步地，限位孔321还可以包括位于其末端的锁定部分3210，锁定部分3210具有相对于限位孔321的其他部分朝向第二连接杆32的轴向延伸的扩孔部 分，使得限位柱331进入锁定部分3210后不易脱出。
为了实现更好的锁紧效果和操作体验，离心管架还可以包括安装在第二连接杆32内的弹性件35，弹性件35被衔接杆33的端部弹性地压缩于第二连接杆32内，可以反向抵接衔接杆33，限位柱331可在弹性件35的弹力下牢牢地抵接在锁定部分3210，从而最大限度地避免了意外松脱的风险。弹性件35可以是压簧，也可以是硅胶、树脂等弹性材料。
本实施例附图示出的是衔接杆33与第二连接杆32只通过一个限位柱331配合的情形，但是需要说明的是，限位柱331也可以成对设置，例如，可以在衔接杆33的周向上关于中心轴对称地设置两个限位柱331，第二连接杆32上对应的长孔320、限位孔321的数量也对应设置，可以提高衔接杆33的运动和锁定的稳定性。
实施例3
如图5所示，在上述实施例的基础上，本实施例对离心管架做出了进一步的改进。
图5示出了本实施例的支撑组件滑动到位后，离心管架的一种使用状态示意图；图6示出了本实施例的支撑组件滑动到位后，离心管架的上下面板的位置关系示意图，图6中，仅为示出第二插孔、第四插孔、锥形孔的相对位置关系，未画出第一插孔101及第一面板10上的其他结构。
本实施例的离心管架的支撑组件30被可滑动地设置在第一面板10上，第一面板10的内表面开设有与其上的至少部分插孔相邻的锥形孔100，如，与第二插孔102相邻，且设置在第二插孔102的同一侧，以对应第二面板20上的第四插孔202的位置，锥形孔100的孔径小于第二面板20上的第四插孔202。
在第一面板10朝上的使用状态下，第一面板10与第二面板20正对，第一面板10上的插孔也与第二面板20上的对应插孔正对，但是锥形孔100与第一面板10上的插孔错开，放置在较大孔径的第二插孔102内的离心管的末端可以由正下方的较小孔径的第四插孔202承托；在第二面板20朝上的使用状态下，需要相对于第一面板10沿预设方向滑动支撑组件30，第二面板20随支撑组件30同步移动，直至第二面板20上的第四插孔202与第一面板10上的锥形孔100正对，则停止滑动支撑组件30，从第二面板20插入的离心管P的末端作为可以抵接在锥形孔100内。
在其他实施方式中，也可以将支撑组件30可滑动地设置在第二面板20上，同时也在第二面板20上开设可承托离心管的锥形孔，这里不再赘述。
如图7，为本实施例的离心管架的内部结构示意图。结合图5和图7所示，本实施例的离心管架包括设置在第一面板10上的载板40和平移机构50，支撑组件30固定在载板40上，平移机构50包括丝杆51，载板40内开设有螺纹孔400，丝杆51穿设于螺纹孔400内，以在转动的过程中带动载板40在第一面板10上移动。
当需要移动支撑组件30时，转动丝杆51，以驱动载板40在第一面板10上沿预定方向移动，当移动至第四插孔202与锥形孔100正对时，则停止转动丝杆51，与第四插孔202对应的规格的离心管则可以由第四插孔202与锥形孔100进行固定。通过调节支撑组件30的工作高度，可以使得离心管架可以适应不同规格的离心管的承托。
为实现对载板40进行限位，丝杆51的两端可以利用固定板511、512进行固定，具体是在第一面板10的长度方向的两端分别固定有固定板511、512，丝杆51的两端分别可转动地固定在固定板511、512上，丝杆51的一端可以通过连接有“Z”形的把手52，通过转动把手52可以驱动丝杆51转动。
综上所述，本发明实施例的离心管架中的上下的第一面板和第二面板上具有不同种规格的插孔，可以通过翻转离心管架来放置更多种型号的离心管，并且，可以通过调节支撑组件的工作长度来使得离心管架可以适用更多不同的应用场景，满足不同的实验需求。而且，本发明实施例还通过将支撑组件设置为可相对于面板滑动，改变上下两块面板之间的插孔的位置关系，实现离心管的末端的承托效果，避免了实验过程中离心管的晃动。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
