Moreover, since the left-right spacing between the second through hole 71 on the leftmost side of the right movable plate 7 and the left end face of the right movable plate 7 is smaller than x, and only the second through hole 71 on the leftmost side of the right movable plate 7 penetrates the accommodating cavity 73, at this time, it is only necessary to ensure that the left movable plate 8 and the right movable plate 7 are inserted and then parallel to the laminate 4, and by means of reasonable position adjustment, 4 third through holes 81 included in each row of the third through holes 81 on the left movable plate 8 are aligned with 4 first through holes 41 from left to right in a corresponding row of the first through holes 41 on the laminate 4, and 4 second through holes 71 included in each row of the second through holes 71 on the right movable plate 7 are aligned with 4 first through holes 41 from right to left in a corresponding row of the first through holes 41 on the laminate 4.
When the latching portion is engaged with the second positioning portion, that is, when the front protrusion 831 and the rear protrusion are respectively latched into the second front recess 7321 and the second rear recess 7322 (see fig. 2), since a left-right interval between the center of the front protrusion 831 and the right end surface of the left movable plate 8 is less than or equal to a left-right interval between the center of the second front recess 7321 and the adjacent second through hole 71, and a left-right interval between the center of the second front recess 7321 and the left end surface of the right movable plate 7 is less than or equal to a left-right interval between the center of the front protrusion 831 and the adjacent third through hole 81, the right-most third through hole 81 on the left movable plate 8 is completely withdrawn from the accommodating chamber 73. Moreover, thanks to the design that x is smaller than d and y/2 is not an integer multiple of d+x, each of the first through holes 41 on the laminate 4 at this time will have a third through hole 81 on the left movable plate 8 or a second through hole 71 on the right movable plate 7 corresponding thereto, and the orthographic projection of the first through hole 41 on the bottom plate 3 at this time will overlap with the orthographic projection portion of the corresponding third through hole 81 or second through hole 71 on the bottom plate 3 but not entirely.
In this embodiment, the left pulling plate 5 further includes a first operating portion 55 connected to the first body portion 51 for facilitating gripping, and the right pulling plate 6 further includes a second operating portion 65 connected to the second body portion 61 for facilitating gripping. Specifically, the first operation portion 55 includes two spaced apart first vertical bars 551 connected to the upper end of the first main body portion 51, and a first cross bar 552 connected between the two first vertical bars 551, and an experimenter may perform a pulling operation on the left pulling plate 5 by holding the first cross bar 552. The second operating portion 65 includes two spaced apart second vertical bars 651 connected to the upper end of the second main body portion 61 and a second cross bar 652 connected between the two second vertical bars 651, and an experimenter may perform a pulling operation on the right pulling plate 6 by holding the second cross bar 652.
The operation mode of using the test tube rack to clean batch test tubes is described as follows:
first, the left pulling plate 5 and the right pulling plate 6 are held by hand and rotated to the right and left sides, respectively, so that the locking portions of the left movable plate 8 are engaged with the first positioning portions, that is, the front protrusions 831 and the rear protrusions are locked into the first front recesses 7311 and the first rear recesses 7312, respectively, and then the left pulling plate 5 and the right pulling plate 6 are pressed down so that the first front locking portions and the first rear locking portions are locked with the first front positioning portions 131 and the first rear positioning portions 141 thereunder, respectively. By the above operation, the left movable plate 8 and the right movable plate 7 are adjusted to a lower level (in order to enable the test tube to be raised above the left movable plate 8 and the right movable plate 7), and the third through holes 81 on the left movable plate 8 and the second through holes 71 on the right movable plate 7 are each aligned with the first through holes 41 on one of the laminate plates 4. Then, 21 test tubes are inserted into 21 first through holes 41 (see fig. 8) in the laminate 4 after passing through the left movable plate 8 or the right movable plate 7, respectively.
After the test tube is inserted, the test tube rack and the test tube are integrally placed in deionized water for cleaning.
After the cleaning is finished, the left pulling plate 5 and the right pulling plate 6 are lifted up, so that the first front clamping portion and the first rear clamping portion are respectively clamped with the first front positioning portion 131 and the first rear positioning portion 141, which are arranged above, the second front clamping portion and the second rear clamping portion are respectively clamped with the second front positioning portion and the second rear positioning portion, which are arranged above, then, the left pulling plate 5 and the right pulling plate 6 are respectively rotated towards the left side and the right side, so that the clamping portion of the left moving plate 8 is matched with the second positioning portion, even if the front protruding point 831 and the rear protruding point are respectively clamped into the second front recess 7321 and the second rear recess 7322. Through the above-described operation, the horizontal heights of the left and right movable plates 8 and 7 rise to be higher than the test tube, and the orthographic projection of the first through holes 41 on the deck 4 on the bottom plate 3 is made to overlap partially but not entirely with the orthographic projection of the corresponding third through holes 81 or second through holes 71 on the bottom plate 3 (see fig. 9). At this time, it is necessary to invert the rack, and the test tube does not fall from the rack while the mouth of the test tube partially coincides with one of the second through holes 71 or one of the third through holes 81 (see fig. 10), so that the washing liquid in the test tube can be drained, thereby efficiently completing the batch washing of the test tube. Moreover, during the cleaning and draining process, the experimenter does not need to touch the test tube by hand, so that the easily polluted elements on the hands/gloves of the experimenter are prevented from entering the cleaned test tube.
It is worth mentioning that each part of test-tube rack need not assemble through extra connecting piece, but directly splice together, simple structure is convenient for unpick and wash and replace vulnerable part.
