Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of test -tube rack especially relates to a sample cryopreservation test -tube rack. BACKGROUND

[0002] In order to guarantee biological activity and structural stability, some biological sample test tubes such as cell strains, DNA / RNA specimens, plasma protein samples etc. need to be stored in a low temperature environment. During the storage process, the droplets on the surface of the sample test tube condense when cold, which easily leads to the freezing adhesion of the sample test tube and the test -tube rack. This phenomenon makes the later sample taking extremely inconvenient.

[0003] At present, the test -tube rack for cryopreservation sample test tubes usually adopts the mode of reducing the contact area between the test tube and the test -tube rack (such as using thinner plate material) to avoid the freezing adhesion caused by freezing. However, this test -tube rack has poor supporting effect on the sample test tube due to the point contact supporting mode. The sample test tube is easily tilted and even the sample is scattered due to the small supporting surface. SUMMARY

[0004] Therefore, the utility model aims at providing a sample cryopreservation test -tube rack to solve the inconvenient use and poor supporting stability of the test -tube rack in the background art.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] The utility model relates to a sample cryopreservation test -tube rack, which comprises

[0007] A base;

[0008] A sliding plate, which is slidingly arranged on the base;

[0009] A top plate, which is arranged on the base and above the sliding plate, and has a plurality of through holes for placing test tubes; the through holes are arranged along the thickness direction of the top plate.

[0010] By adopting the above technical scheme, the base in the utility model plays a supporting role on other part structures, the top plate with a plurality of through holes plays a limiting role on the sample test tubes placed in the through holes, and can cooperate with the base to fix the position of the test tube to avoid the tilting of the test tube. The sliding plate installed on the base directly contacts the bottom of the test tube. If the bottom of the test tube is frozen and adhered, the user can move the sliding plate to separate the test tube from the sliding plate without directly applying force to the test tube, so that the test tube can be conveniently taken off from the utility model. Compared with the prior art, the utility model has a larger contact area with the surface of the test tube, better supporting effect, and is easy to take out after freezing adhesion of the test tube, and is more convenient to use.

[0017] Further, the drive rod is provided in multiple, and the multiple drive rods are uniformly distributed along the sliding direction of the sliding plate.

[0018] By adopting the above technical scheme, the structure design of the drive rod provided in multiple increases the action points of the drive rod and the sliding plate, so that the process of driving the relative sliding between the sliding plate and the base can be performed synchronously at multiple points, making the operation process more convenient and labor-saving, and avoiding the shaking of the whole due to the rotation of the drive rod.

[0020] By adopting the above technical scheme, the limiting plate can further improve the support stability of the test tube in cooperation with the top plate. The limiting plate is slidingly arranged on the base and is in threaded cooperation with the rod body, so that the limiting plate can be lifted and lowered along with the rotation of the rod body, and it is easier to be detached when the test tube is frozen and adhered.

[0021] Further, the limiting plate further comprises a sleeve corresponding to the installation positions of the limiting holes one by one, and the inner diameter of the sleeve is consistent with the limiting hole.

[0046] In the present embodiment, the sample cryopreservation test tube rack comprises a base 1, a sliding plate 2 and a top plate 3. The base 1 comprises a bottom plate and two side plates arranged vertically on the bottom plate. The top plate 3 is detachably arranged on the top of the side plate of the base 1 by bolt connection or clamping. The top plate 3 has a plurality of through holes 31 arranged along the thickness direction of the top plate 3. The through holes 31 are circular holes. The diameter of the through holes 31 is consistent with the outer diameter of the sample test tube. The top plate 3 is parallel to the bottom plate of the base 1. The sliding plate 2 is a rectangular plate slidingly arranged on the base 1. The sliding plate 2 is below the top plate 3.

The sample test tube passes through the through hole 31, and the bottom of the sample test tube abuts against the upper surface of the sliding plate 2. When the sample test tube is frozen and adhered, the user can make the sliding plate 2 slide relative to the base 1, so that the sliding plate 2 is separated from the bottom of the sample test tube, and then the sample test tube is pressed to separate the sample test tube from the top plate 3, thereby achieving the technical effect that the sample test tube frozen and adhered is separated from the test tube rack without pulling the sample test tube and avoiding sample spilling.
