Consumable uncovering and covering structure

Abstract

The invention discloses a consumable uncovering and covering structure. The structure comprises an adapter plate, a consumable cover fixing plate and a consumable body fixing plate, wherein the adapter plate, the consumable cover fixing plate and the consumable body fixing plate are sequentially arranged from top to bottom; the adapter plate and the consumable body fixing plate are movably arranged on a plurality of vertically arranged guide rods in a sleeving mode and can move up and down along the guide rods, a first guide rod upper limiting block is arranged at the upper end of each guide rod and located above the adapter plate, and a first guide rod lower limiting block is arranged at the lower end of each guide rod and located below the consumable body fixing plate; the adapter plateis connected with the consumable cover fixing plate through a plurality of second guide rods; a consumable cover fixing mechanism is arranged at the bottom of the consumable cover fixing plate; and the consumable body fixing plate is provided with a plurality of consumable body fixing grooves. Through the consumable uncovering and covering structure, sample pollution caused by manual operation canbe avoided; and meanwhile, the operation efficiency of uncovering and covering a consumable can be improved, and manual fatigue strength can be reduced.

Description

technical field [0001] The invention relates to the field of instrument automation, in particular to a consumable switch cover structure. Background technique [0002] Nucleic acid is the carrier of the genetic information of organisms. Whether it is to study nucleic acid sequence and structure, or to explore gene function and expression, it is necessary to separate, purify and detect nucleic acid. [0003] With the advancement of science and technology, the automation of nucleic acid extraction and detection equipment will be an inevitable trend. However, fully automatic nucleic acid detection should not only be limited to the automation of nucleic acid extraction and detection process, but should also include steps such as sample addition, product transfer, and waste treatment, so as to minimize the interaction between operators and samples, reagents, and reaction products. , and contact with waste consumables to reduce the risk of biological contamination and biological ...

Problems solved by technology

[0009] However, the opening and closing operations of the existing nucleic acid reaction consumables are all done manually, which will increase the risk of sample contamination. At the same time, the efficiency of manual operation is low and the intensity of manual fatigue is high.
