Coiled test tube rack

[0030] see figure 1 and figure 2 :

[0031] The invention discloses a coiled test tube rack, which includes a coiled column 1, the coiled column 1 includes a mounting base 11, a column 13 is fixedly mounted on the mounting base 11, and a rotating ring 12 is provided outside the column 13 , the rotating ring 12 can rotate around the column 13, and the top of the column 13 is provided with a sliding groove 131, and a limit block 132 is slidably installed in the sliding groove 131, and a limiting block 132 is installed on the top of the rotating ring. Bit slot 121.

[0032] In this embodiment, the inner wall of the sliding groove 131 is a rough surface, the length of the limiting block 132 is greater than the length of the limiting groove 121, that is, when the limiting block 132 slides to the limiting groove 121 When it is inside, a part of the limiting block 132 is still located in the slot of the slide 131, and a moving piece is fixedly installed above the limiting block 132

[0037] see image 3 :

[0038] The difference between this embodiment and Embodiment 1 is that the coiled test tube rack disclosed in this embodiment has two coiled columns 1, and the two coiled columns 1 are fixedly installed on a cuboid base at intervals. 5 on.

[0039] Further, in this embodiment, there is a second storage chain 4 above the first storage chain 3, and the second storage chain 4 and the first storage chain 3 have the same chain structure, and the second storage chain 4 has the same chain structure as the first storage chain 3. One end of a storage chain 3 and a second storage chain 4 are fixedly connected to the rotating ring 12 of a coiled column 1, and the other ends of the first storage chain 3 and the second storage chain 4 are fixedly connected to another coiled column 1 on the rotating ring 12.

[0040] In this embodiment, the storage hole on the first storage chain 3 is a blind hole with an upward opening, and the shaft 33 of the second storage chain 4
