Storage box of eight-connection pipe cover

Technical Field

The utility model relates to the technical field of PCR reaction devices, in particular to a storage box with eight connecting pipe covers.

Background

Polymerase Chain Reaction (PCR) is a molecular biology technique for amplifying and amplifying specific DNA fragments, and can be regarded as special DNA replication in vitro, and the greatest feature of PCR is that a trace amount of DNA can be greatly increased. In the field of molecular biology, PCR is often used to amplify specific DNA (deoxyribonucleic acid) fragments, and then to detect and diagnose genetic diseases, pathogens, and tumors. The PCR technology has the characteristics of strong specificity, high sensitivity, good automation and repeatability, accurate quantification, less pollution and the like, so the PCR technology gradually becomes an important technical tool in molecular biology and other fields. The PCR reaction needs to be performed in a PCR tube. Currently, PCR technology is used for nucleic acid detection. After a sample is manually collected, adding a sample solution into a PCR tube, adding a system reagent into the PCR tube, covering the PCR tube with a cover, and putting the PCR tube into PCR equipment for amplification and fluorescent quantitative detection. Because the number of samples for daily molecular biology detection is large, and the volume of a single PCR tube is small, in order to realize large-throughput detection and convenient transfer, the PCR tubes on the market are usually in an eight-row form, that is, eight PCR tubes are connected in sequence into one row, and correspondingly, the caps of the eight-row PCR tubes are also in a form that eight caps are connected into one row, as shown in FIG. 1. The mode that adopts artifical gland in the past is with the tube cap pressure equipment at PCR eight ally oneself with pipe, but this kind of way is high to staff's requirement, and wastes time and energy, inefficiency, still has the risk of sample pollution and infection, consequently, the mode of traditional manual operation has not satisfied present demand, and the automation instrument replaces traditional manual experiment and has been the trend in current market, adopts the automatic gland of machine realization PCR eight ally oneself with pipe promptly.

The prior art discloses a PCR reaction tube press cover system and a using method thereof, the system comprises a reaction tube carrier arranged on the upper surface of a bearing base and two ball screws penetrating through the upper surface of the bearing base, and the reaction tube carrier is positioned between the two ball screws; the two ball screws are respectively provided with a driving wheel and a driven wheel which are connected through a connecting piece; one end of each of the two ball screws is connected with a gland device, and the gland devices are positioned at the upper part of the reaction tube carrier; the other end of the ball screw is connected with a driving motor; the gland device comprises a movable base, a pipe cap carrier and a cover plate, and a ball screw penetrates through the movable base; the interior of the movable base is provided with a hollow first groove; the inside of the pipe cover carrier is provided with a strip-shaped hollow second groove; the pipe cover carrier is movably arranged in the first groove, and the cover plate is movably arranged on the upper surface of the movable base through a fixing piece; the ball screw penetrates through the movable base to realize the up-and-down movement of the movable base. The movable base is of an internal hollow structure, a first groove is formed in the hollow edge, and the first groove can facilitate the movable placement of the pipe cover carrier. The tube cap carrier is internally provided with a strip-shaped hollow second groove which is used for placing the PCR reaction tube cap so that the cap pressing device can press the PCR reaction tube cap on the PCR reaction tube in the downward movement process. This patent moves downward by a capping device, thereby pressing a cap onto a PCR reaction tube. The hollow second recess of bar of the tube cap carrier of this patent can only place a tube cap, just need place the tube cap once more after carrying out a gland, can't carry out continuous gland, and is inefficient, uses inconveniently.
