The invention relates to a shading positioner suitable for a DNA sequencing instrument reaction cabin. The shading positioner comprises a slidable positioning and locking block and a turnover pedestal assembly, and the slidable positioning and locking block and the turnover pedestal assembly are elastically connected and are used for opening and closing a reaction chip mounting seat and a reaction cabin pedestal in a reaction cabin assembly; the slidable positioning and locking block is provided with a locking jaw, and after mounting is completed, the upper end surface of the slidable positioning and locking block is in contact with the inner side surface of the reaction chip mounting seat, and the locking jaw is hooked on the outer side end portion of the reaction chip mounting pedestal; and a shading positioning assembly is fixed to the reaction cabin pedestal, and the slidable positioning and locking block is outward pressed when the reaction chip mounting seat is opened. The shading positioner suitable for the DNA sequencing instrument reaction cabin comprises two symmetrically arranged composition parts, and the reaction cabin assembly can be conveniently opened or closed through a spring assembly between the two parts and a hooking structure, so a chip can be simply and easily replaced, and the shading positioner has the advantages of simple operation and stable structure.
Description
technical field [0001] The invention relates to the field of DNA sequencing, in particular to a light-shielding positioning device suitable for a reaction chamber of a DNA sequencer. Background technique [0002] In the field of DNA sequencing technology, the reaction chip component is the core part of the tester, and its operation convenience and compact structure are important indicators. [0003] The Chinese patent "Reaction Chamber for DNA Sequencer" in the prior art discloses a reaction chamber structure, which includes two parts that cooperate with each other, including the reaction pool body and the mounting seat, and the reaction pool body is provided with an annular concave The installation base is provided with a through installation cavity, and the installation cavity is provided with a plurality of positioning slots, and each positioning slot is provided with a sliding tongue that slides into the installation cavity to hold the sequencing chip; the reaction pool ...
