Problems solved by technology

At present, some pipettes are equipped with an adjustment mechanism to adjust the distance between the tips. Usually, the adjustment method is a knob. Matching, it is easy to cause liquid pollution, and it is impossible to realize stepless adjustment of the distance, and the distance adjustment components of the existing pipette are relatively complicated, which cannot meet the requirements of overall disinfection and sterilization of the pipette

Abstract

The invention provides a button type spacing adjusting device and a pipettor. The button type spacing adjusting device in the technical scheme comprises a shell, a front adjusting button, a rear adjusting button and a driving wheel, wherein the front adjusting button and the rear adjusting button are connected to the shell in a floatable manner, the driving wheel is rotatably connected to the interior of the shell for correspondingly linking a plurality of spaced suction heads to move so as to enlarge or reduce the spacing between adjacent two suction heads when the driving wheel moves forward or reversely, one-way transmission mechanisms are correspondingly arranged between the front adjusting button and the driving wheel and between the rear adjusting button and the driving wheel, and the one-way transmission mechanism is used for correspondingly linking the driving wheel to rotate forwards or reversely when the front adjusting button or the rear adjusting button is pressed downwards. The driving wheel is driven to rotate in a small range through the short-distance downward pressing action of the front adjusting button and the rear adjusting button, so that the effect of fine adjustment is achieved, and the precision of adjusting the distance between the suction heads is improved.

Description

technical field [0001] The invention relates to the technical field of laboratory appliances, in particular to a button-type spacing adjustment device and a pipette. Background technique [0002] Pipettes are widely used in biology, chemistry and other fields. At present, the tip spacing of most multi-channel pipettes used in laboratories is not adjustable, but they are generally used in laboratories to hold Liquid containers usually have different specifications, and the density and spacing of slots on containers of different specifications are different. Since the distance between the tips of the existing multi-channel pipette is fixed, when it is necessary to perform a pipetting operation on containers of different specifications, it is necessary to replace pipettes of different specifications to meet the requirements for pipetting. At present, some pipettes are equipped with an adjustment mechanism to adjust the distance between the tips. Usually, the adjustment method ...
