Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of testing tables, and particularly relates to a testing table used for low-temperature treatment of strain samples. Background Art
[0002] Cryopreservation can store blood, bacteria, cells, etc. for a long time for subsequent testing. When using existing cryopreservation boxes, they need to be taken out of the cryostat and the samples stored in the cryopreservation boxes are used for subsequent testing or bacterial culture.
[0003] At the same time, during the strain culture test process, the sample needs to be taken out of the refrigerator first, and then thawed to a smoothie state with strains that can be separated using tools, and then transferred to the culture dish using tools.
[0004] When inspectors need to deal with a large number of strain cultures, and each sample in a cryopreserved tube needs to wait for thawing, sampling, transfer, etc., this will cause the freezer to need to be opened and closed frequently, and the biological freezing temperature inside the refrigerator will be difficult to maintain at -86 degrees, affecting the preservation of frozen biological samples. At the same time, frequent opening and closing can easily cause damage to the refrigerator.
[0005] If all the cryopreservation tubes of the strain samples to be cultured and tested are taken out, it will be difficult to complete all of them in a short period of time. If the strain samples in the cryopreservation tubes are thawed to liquid, the samples are easily invalidated and cannot be put back into the refrigerator for freezing and subsequent use.
[0006] Therefore, after taking out the samples from the cryostat, how to maintain them at a relatively low temperature (below -10°C) for a long time, without the need for experimenters to walk back and forth between the test bench and the refrigerator, and to avoid frequent opening of the refrigerator, is the technical problem to be solved in this case. Utility Model Content
[0007] The utility model aims to solve the above problems existing in the prior art and provides a test bench for low-temperature treatment of strain samples.
[0008] The purpose of the utility model can be achieved through the following technical solutions: a test bench for low-temperature treatment of strain samples, characterized in that it includes a top plate and supporting cabinets arranged at the bottom of both sides of the top plate, an opening is arranged on the top plate, a low-temperature operation panel is flipped in the opening, and a refrigeration instrument is installed on one side of the low-temperature operation panel.
[0009] The working principle of the utility model is as follows: when low-temperature operation is not required, the other side of the low-temperature operation board, that is, the side without the refrigeration instrument, is located at the top and combined with the top plate to form an integral operation platform. In this state, the operation platform will not be affected by the volume of the refrigeration instrument and will not interfere with the experimental operation; when low-temperature operation is required, the low-temperature operation board is turned over, and the side with the refrigeration instrument installed will turn up for the operator to use, and can be turned down after use, which is very convenient.
[0010] In the above-mentioned test bench for low temperature treatment of strain samples, a hollow rotating shaft is arranged in the middle of the low temperature operation board, and a threading hole communicating with the inner cavity of the rotating shaft is opened on one side of the low temperature operation board where the refrigeration instrument is installed.
[0011] The above-mentioned test bench for low-temperature treatment of strain samples also includes a locking member for locking the low-temperature operation panel and an unlocking plate for unlocking the low-temperature operation panel.
[0012] In the above-mentioned test bench for low temperature treatment of strain samples, the locking member includes two symmetrically arranged locking blocks, and two locking grooves are symmetrically arranged on one side of the low temperature operation plate, and the two locking grooves are used for two locking blocks to be inserted respectively to lock the low temperature operation plate.
[0013] In the above-mentioned inspection table for low-temperature treatment of strain samples, two slots are symmetrically arranged on one side of the opening, and the two locking slots each include a filling slot and a slot opened in the middle of the side wall of one side of the filling slot. The two slots and the two filling slots are respectively connected to form two slide slots, and the two locking blocks are respectively located in the two slide slots and can move along the length direction of the slide slots. The two locking blocks each include a filling block and an insertion block.
[0014] In the above-mentioned test bench for low-temperature treatment of strain samples, limiting grooves are provided on both side walls of the two slots, and limiting blocks are provided on both sides of the two filling blocks.
[0015] In the above-mentioned test bench for low-temperature treatment of strain samples, one end of the unlocking plate is hinged to one end of the two filling blocks away from the low-temperature operation plate, and the top plate is provided with a connecting groove between the two grooves for connecting the two grooves.
[0016] In the above-mentioned test bench for low-temperature treatment of strain samples, a bottom edge of one end of the unlocking plate away from the low-temperature operation plate is provided with a rounded corner.
[0017] In the above-mentioned test bench for low-temperature treatment of strain samples, a hand-grip groove is provided on the top plate at a side of the connecting groove away from the opening, and the hand-grip groove is connected to the connecting groove.
[0018] Compared with the prior art, it has the following advantages:
[0019] 1. A reversible low-temperature operation board is designed. When a large number of cryopreservation tubes need to be operated, it can be turned over and used when the refrigeration instrument is needed, which is very convenient. When the refrigeration instrument is not needed, only the low-temperature operation board needs to be turned back to the bottom to keep the surface of the inspection table flat, avoiding the refrigeration instrument from occupying the inspection table space.
[0020] 2. By designing an insert and disengagement locking structure, the locking groove cleverly forms an operating groove after the locking block is disengaged, so that people can hold it to conveniently flip the low-temperature operating panel.
[0021] 3. The unlocking plate can be pulled out and rotated upwards to pull the unlocking block. It is easy to operate and can avoid accidental overturning caused by touch, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS

The second method is selected in this embodiment.
[0032] To be more specific, a hollow rotating shaft 5 is provided in the middle of the low-temperature operating panel 4, and a threading hole 6 connected to the inner cavity of the rotating shaft 5 is provided on one side of the low-temperature operating panel 4 on which the refrigeration instrument is installed; the power supply line of the refrigeration instrument passes through the threading hole 6 and passes out through the rotating shaft 5. In this design, when the low-temperature operating panel 4 is turned over, the power supply line will not be entangled or knotted.
[0033] To be more specific, it also includes a locking member 7 for locking the low-temperature operating panel 4 and an unlocking plate 8 for unlocking the low-temperature operating panel 4.

[0036] To explain in further detail, one end of the unlocking plate 8 is hinged to the end of the two filling blocks 20 away from the low-temperature operating panel 4, and a connecting groove 17 for connecting the two grooves 11 is opened between the two grooves 11 on the top plate 1; the depth of the connecting groove 17 is equivalent to the thickness of the unlocking plate 8. In the locked state, the unlocking plate 8 is embedded in the connecting groove 17 and the two grooves 11, and the top surface of the unlocking plate 8 is flush with the top surface of the top plate 1. When unlocking, the unlocking plate 8 is lifted and rotated upward, so that a person can hold it to pull the unlocking block, and pulling it in the direction away from the low-temperature operating panel 4 can pull out the locking block 9, thereby unlocking the low-temperature operating panel 4. The structure is ingenious.
[0037] To be more specific, a bottom edge of one end of the unlocking plate 8 away from the low-temperature operation plate 4 is provided with a rounded corner 18 ; the rounded corner 18 is provided to facilitate the unlocking plate 8 to rotate into the connecting groove 17 .
[0038] To elaborate further, a hand groove 19 is provided on the top plate 1 on the side of the connecting groove 17 away from the opening 3, and the hand groove 19 is connected to the connecting groove 17; the depth of the hand groove 19 is equivalent to the thickness of the unlocking plate 8, and due to the setting of the rounded corner 18, the finger can be inserted under the rounded corner 18, so that the unlocking plate 8 can be easily picked out and lifted.
[0039] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
