    • An apparatus for drawing liquid samples and the like into an analytical testing machine, which includes a vertically extending guide rail fixed to a base, a movable support member slidably mounted on the guide rail for movement between an upper position and a lower position, a stopper for blocking movement of the movable support member above the upper position, an arm holding a probe at an end thereof and pivotally mounted to the movable support member at the other end, an arciform guide projecting from a pivot member so as to engage the upper surface of a fixed support member when the movable support member in its upper position and the arm is pivoted upward, and a detent mechanism fixed to the movable support member and elastically engageable with the pivot member for releasably holding the arm in a first predetermined inclination. When the movable support member is in its upper position, the arm is pivotable upward to a second predetermined inclination so as to bring the arciform guide into a position where it is vertically supported by the fixed support member.
    • 一种用于将液体样品等拉入分析试验机的装置,该分析试验机包括固定在基座上的垂直延伸的导轨,可滑动地安装在导轨上用于在上部位置和下部位置之间移动的可动支撑构件, 用于阻止可移动支撑构件在上部位置上方的运动;臂在其一端保持探针并在另一端枢转地安装到可移动支撑构件;弓形引导件,其从枢转构件突出以接合上表面 当可移动支撑构件处于其上部位置并且臂向上枢转时的固定支撑构件,以及固定到可动支撑构件并与枢转构件弹性接合以用于可释放地将臂保持在第一预定倾斜度的止动机构。 当可移动支撑构件处于其上部位置时,臂可向上枢转到第二预定倾斜度,以便将弓形引导件引导到由固定支撑构件垂直支撑的位置。

    • The present invention is concerned with a tubing pump used for conveying various kinds of fluids with a plurality of tubes different from each other in inner diameter and pressed by a rotating tube-pressing device. Each of the tubing parts of tubes to be pressed by the tube pressing device is connected to the remaining parts of the tube so as to be replaceable and to compose a tube unit in cooperation with the remaining parts. Relative position coordinating pins are provided for enabling correct replacement of tubing parts assembled into the tube unit to be pressed.
    • 本发明涉及一种用于输送具有内径不同的多个管的各种流体的管式泵,并通过旋转管压装置进行挤压。 由管按压装置按压的管的每个管道部分连接到管的其余部分,以便可替换,并与其余部分协作组成管单元。 提供了相对位置协调销以使得能够正确地更换组装到要被按压的管单元中的管件。
