Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration of reagent tubes, and in particular to a reagent bin refrigeration module. Background Art

[0002] Existing reagent samples are usually placed in reagent tubes and are usually refrigerated at low temperatures to increase the storage time. Since the number of reagent samples is large, a test tube rack is usually set in the refrigeration chamber to store a large number of test tubes.

[0003] However, during the actual refrigeration storage process, the test tubes and the test tube racks freeze and stick to each other due to the refrigeration effect, which causes the test tubes to break. At the same time, existing test tube racks are usually installed exposed in the refrigeration space. During the process of taking reagents, the end cover needs to be opened, which causes a large amount of cold air to leak, making the refrigeration effect worse. At the same time, the entry of outside air causes water vapor in the air to condense, further exacerbating the freezing problem and making it inconvenient to take the test tubes.

The upper end of the refrigeration bin 1 is sealed by setting a sealing cover 4, and the through hole 41 is sealed by a sealing column 20. The purpose of fixing the reagent tube 7 is achieved by setting a folding sealing bag 5 to avoid shaking during transportation.

[0036] The refrigeration component is installed in the lower end cavity of the refrigeration warehouse 1. The refrigeration component includes a pair of refrigeration plates 10 symmetrically distributed on both sides of the refrigeration slot 39. A cooling inner cavity 30 is provided in the refrigeration plate 10. A cooling coil 9 is provided in the cooling inner cavity 30. The cooling coil 9 is attached to the refrigeration plate 10. The refrigeration plate 10 is electrically connected to the refrigeration pump in the control base 8. A hollow tubular heat conduction pipe 29 is provided at the lower end of the refrigeration slot 39. An insulating layer 28 wrapping the refrigeration component is provided on the inner wall of the inner cavity at the lower end of the refrigeration warehouse 1. Adjacent refrigeration slots 39 are connected by multiple groups of linearly distributed through holes 12.

[0037] By arranging the refrigeration plate 10, the cooling coil 9 and the heat conduction pipe 29, the purpose of refrigerating and preserving the lower end of the reagent tube 7 is achieved, and the through hole 12 is used to connect the lower end cavities of each refrigeration slot 39 to ensure uniform temperature refrigeration.

[0038] A sealing plug 6 is provided at the upper end of the reagent tube 7. The reagent tube 7 is vertically plugged and installed along the refrigeration slot 39, and the sealing plug 6 is located in the through hole 41.

The pressure rod 23 slides through the fixed baffle, and the second spring 24 is pressed between the pressure plate 22 and the fixed baffle.

[0040] During the feeding process, the reagent tube 7 is plugged in so that the reagent tube 7 is vertically plugged in along the rubber ring 31. At this time, the rubber ring 31 is deformed and expanded and is sleeved on the reagent tube 7. During the material removal process, the second spring 24 is compressed by squeezing the pressure rod 23, and the horizontal tooth plate 27 is engaged with the second linkage gear 34, and drives the second linkage gear 34 to rotate, thereby pulling the first linkage gear 19 to rotate, and the rotation of the first linkage gear 19 is used to drive the longitudinal tooth plate 32 to rise. During the rising process of the longitudinal tooth plate 32, the first spring 18 is compressed, and the friction between the rubber ring 31 and the reagent tube 7 is used to drive it to rise synchronously, so that the upper end of the reagent tube 7 moves to the upper end of the sealing strip 40, which is convenient for extraction.

[0041] Example 2: Based on Example 1, the lower end inner cavity of the refrigeration chamber 1 is rotatably mounted with multiple sets of rotating cone seats 11 corresponding to the refrigeration slots 39. The upper end of the rotating cone seat 11 is provided with a hemispherical card slot 13, and the lower end of the reagent tube 7 is inserted into the card slot 13.

[0042] By providing the rotating cone seat 11, the reagent tube 7 can be installed in a rotating manner.

[0043] The lower end of the rotating cone seat 11 is provided with a vertical rod 36 extending vertically to the outside of the lower end of the refrigeration warehouse 1. The vertical rod 36 is driven by a driving assembly. The lower end bearing of the vertical rod 36 is rotatably inserted into the upper end of the control base 8. A driven gear 15 is fixedly sleeved on the vertical rod 36. The driving assembly includes a transmission gear chain 16 and a driving gear 14. The inner side of the transmission gear chain 16 is engaged with the driven gear 15 on multiple groups of vertical rods 36, and the outer side of the transmission gear chain 16 is engaged with the driving gear 14. The driving gear 14 is driven by a reduction motor 37 installed in the control base 8.

[0044] The driving gear 14 is driven to rotate by the reduction motor 37, and then through the meshing connection, the transmission gear chain 16 synchronously drives multiple groups of driven gears 15 to rotate, pulling the rotating cone seat 11 to rotate slowly, so that the outer wall of the reagent tube 7 and the inner wall of the heat pipe 29 keep rotating, avoiding freezing and adhesion due to refrigeration.

[0045] Example 3: On the basis of Example 2, a side plate 26 is slidably installed on the side wall of the adjusting inner cavity 21, the front end of the side plate 26 faces the reagent tube 7, and the front end of the side plate 26 is provided with a friction layer 35 that fits the upper side wall of the reagent tube 7, one end of the side plate 26 faces the transverse tooth plate 27, and a third spring 25 is pressed between the side plate 26 and the transverse tooth plate 27, and an elastic airbag layer is provided between the third spring 25, the friction layer 35 and the side plate 26.

[0046] By arranging the side plate 26 and the friction layer 35 to cooperate, during the extrusion process of the pressure rod 23, the third spring 25 is driven to compress and the side plate 26 is caused to slide. The friction between the friction layer 35 and the outer wall of the reagent tube 7 is utilized to drive the reagent tube 7 to rotate in the slot 13, thereby preventing the reagent tube 7 from sticking to the rotating cone seat 11.
