Abstract
Description
Technical Field
[0001] This utility model relates to the field of biochemical detection technology, and in particular to a test tube rack and a sampling transfer system. Background Technology
[0002] Test tubes are common instruments in biology and chemistry laboratories, used as reaction containers for small amounts of reagents. They are convenient to use, whether at room temperature or under heat, and are widely used in hospitals and testing institutions, enjoying popularity among medical personnel. Existing test tube racks typically consist of a vertical plate, a base plate, and a perforated plate. Test tubes are inserted into the holes on the perforated plate to secure them for easy access. However, existing test tube racks are functionally limited and do not meet the needs of operators requiring diverse use of the racks. The only solution is the time-consuming and laborious process of moving test tubes back and forth, which is very inconvenient. Furthermore, existing test tube racks are mainly arranged in a single row, resulting in poor stability when sampling at the front. Utility Model Content

A buckle groove adapted to the buckle is provided on the test tube rack body. A placement groove adapted to the placement protrusion is provided at the upper end of the insertion unit. Therefore, the elastic clamping structure is used to limit the position of test tubes within the insertion unit. The elastic clamping ring achieves its positioning on the test tube rack body by engaging with the buckle and the buckle groove.
[0007] The bottom of the insertion unit is provided with a limiting arc groove that fits the test tube. Therefore, the limiting arc groove fits the bottom of the test tube, facilitating stable placement of the test tube.
