Description

PCR reagent split charging box Technical Field The utility model relates to the technical field of kits, in particular to a PCR reagent split charging box. Background At present, most reagent manufacturers are large packages, namely, a large number of reagent (PCR amplification reagent) manufacturers provide large-capacity packages (for tens of experiments), a whole bottle of reagent is not used in a single experiment, the reagent can be used after being dissolved, only a part of the reagent is used in each experiment, the rest part of the reagent needs to be repeatedly frozen and thawed (frozen and preserved and re-dissolved in use), and the activity and stability of the reagent can be obviously reduced by re-dissolution (repeated frozen and thawed), so that the accuracy and reliability of an experiment result are influenced. In order to solve the problem of repeated freeze thawing, the laboratory generally adopts the method that after the large-package reagent is dissolved for the first time, the large-package reagent is immediately split into small parts, the small-part split-package reagent is put back into a certain vacancy of a reagent box provided by an original factory for storage, but the design of the reagent box of the original factory is mainly used for accommodating large-package reagent tubes carried by the reagent box when the reagent box leaves a factory, the split-package tubes cannot be vertically fixed in a box like the original package tubes, the split-package tubes can only incline or lie horizontally, not only occupy unreasonable space, but also the sealing performance of a cover is possibly poor in a non-vertical state, so that the reagent is easy to leak, waste is caused, a working table is polluted, even other reagents are influenced, and the reagent box also usually contains a positive reference substance for experimental quality control, if the positive reference substance and the reagent to be detected split-packaged by the laboratory are stored in the same open reagent box lattice, cross pollution risk exists, and once the positive reference substance leaks, the split-package reagent beside is easy to pollute, so that a false positive result appears in a subsequent experiment. Disclosure of utility model Based on the above description, the utility model provides a PCR reagent dispensing cartridge, which solves the technical problems pointed out in the background art. The technical scheme for solving the technical problems is as follows, a PCR reagent split charging box comprises: The box body comprises a lower seat, a first boss and a second boss are arranged on the lower seat, the first boss and the second boss are arranged at intervals, and pipe holes which vertically penetrate into the lower seat are respectively formed in the first boss and the second boss, namely a reagent pipe hole and a comparison pipe hole; The cover body is detachably arranged with the box body and comprises a first mark cover and a second mark cover, and the first mark cover and the second mark cover are respectively sleeved on the outer sides of the first boss and the second boss. On the basis of the technical scheme, the utility model can be improved as follows. Further, the total number of the reagent tube holes is ninety-six, and the reagent tube holes are arranged in eight rows and twelve columns. Further, the number of the control tube holes is ten, four of the control tube holes are large holes, six of the control tube holes are small holes, and the control tube holes are arranged in five rows and two columns. Further, the length and the width of the first mark cover are respectively larger than those of the second mark cover so as to be distinguished. Further, the first mark cover and the second mark cover are respectively provided with a mark cavity. Further, the front and back sides of the boss I and the boss II are both provided with grooves, the front and back sides of the mark cover I and the mark cover II are both provided with accommodating cavities, the PCR reagent split charging box further comprises two groups of locking structures, each locking structure comprises a sliding strip positioned in the accommodating cavity, two groups of limiting protruding blocks matched with the grooves are respectively arranged on one opposite sides of the sliding strips, and each locking structure further comprises an adjusting transmission part for enabling the two groups of limiting protruding blocks to move oppositely or reversely. Further, the center department at mark lid one and mark lid two tops all has seted up the perforation, adjust the drive unit and still including rotating the transmission shaft of connecting in corresponding perforation inboard, the bottom of transmission shaft is fixed with the meshing wheel, is provided with the driving strip in the left and right sides of meshing wheel, and the driving strip is fixed with a plurality of meshing teeth with the draw runner looks fixed c
