Problems solved by technology

[0002] Many experiments in hospital laboratories, chemical and biological industries often face the need to detect and process a large number of samples, or require the operation of multiple detection reagents. The pipette is a small-capacity liquid transfer and sampling device commonly used in such experiments. , used to draw samples or reagents in experimental operations, especially more frequently in the use of 96-well plates. During experimental operations, the operator needs to adjust the dose of the pipette according to the different doses of the liquid drawn. Us...

Embodiment 1

[0017] Such as Figure 1-2 The shown dose adjustment device of a pipette includes: a cylindrical portion 1 with an open tooth end, a double-layer gear 2, a number wheel 3, the open-tooth end of the cylindrical portion 1 and the double-layer gear 2 The small tooth layer meshes, the large tooth layer of the double-layer gear 2 meshes with the number wheel 3. The cylinder part 1 drives the sliding rod to slide, and the other end opposite to the open tooth end is provided with anti-slip patterns for External rotation adjusts the dose. Through the meshing of multiple compact gears, the force of rotation adjustment is greatly reduced on the premise of ensuring accurate dosage adjustment.

Embodiment 2

[0019] Such as Figure 1-6 The shown dose adjustment device of a pipette includes: a cylindrical portion with an open toothed end 1, a double-layer gear 2, and a number wheel 3. There are three number wheels 3, which are the number one number wheel 4, Number two number wheel 5 and number three number wheel 6, the number wheels are meshed and connected by small gears with long and short teeth at intervals, and the open end of the cylindrical portion 1 meshes with the small tooth layer of the double-layer gear 2, so The large tooth layer of the double-layer gear 2 meshes with the full tooth layer 12 of the number one number wheel 4, and the single tooth layer 11 of the number one number wheel 4 meshes with the long teeth 9 of the pinion gear 7. The full tooth 10 of the gear 7 meshes with the full tooth layer 12 of the second number wheel 5, and the single tooth layer 11 of the second number wheel 5 meshes with the long teeth 9 of the second pinion 8, and the second small The ful...

Abstract

The invention discloses a dosage adjustment device of a pipettor. The dosage adjustment device of the pipettor comprises a round tube part provided with a tooth punching end, double-layer gears and a digit wheel, wherein the tooth punching end of the round tube part is meshed with a small tooth layer of the double-layer gears, a big tooth layer of the double-layer gears is meshed with the digit wheel, the inside of the round tube part drives a sliding rod to slide, and anti-skid threads are arranged at the other end, opposite to the tooth punching part, of the outside of the round tube part and are used for rotation of the outside to adjust a dosage. Because a plurality of compact gears are meshed, on the premise that accurate dosage adjustment is ensured, strength for rotating adjustment is greatly reduced. Great strength is not needed, the dosage can be adjusted easily and accurately, the whole adjustment process is smooth in motion, and the dosage adjustment device of the pipettor is suitable for routine work carried out every day.

Description

Technical field [0001] The invention relates to the field of micro-liquid-taking instruments, in particular to a dose adjusting device of a pipette. Background technique [0002] In hospital laboratories, many experiments in the chemical and biological industries often face the need to detect and process large quantities of samples, or require multiple detection reagents. Pipette is a small-volume liquid transfer and sample addition device commonly used in such experiments. It is used to draw samples or reagents in experimental operations, especially in the use of 96-well plates more frequently. During experimental operations, the operator needs to adjust the dose of the pipette according to the amount of liquid to be drawn, usually the pipette The adjustment of the digital pulley is to drive the push rod by rotating the external digital pulley to cause the internal solvent to change to absorb the corresponding dose of solution. Since the setting position of the digital pulley is...
