Description

Technical Field

[0001] The utility model relates to the technical field of cryopreservation tubes, in particular to a cryopreservation tube bearing structure. Background Art

[0002] Cryopreservation tubes generally refer to strain preservation tubes, which are mainly composed of preservation fluid, preservation tubes and small ceramic beads. They are a container for preserving strains in the laboratory and are used for the preservation or transfer of strains. Generally, there are 25 small ceramic beads in the strain preservation tube for the adsorption and preservation of bacteria. They can preserve common bacteria, fastidious bacteria, molds, yeasts and other fungi. They can also be preserved in strain preservation tubes under low temperature conditions. Therefore, strain preservation tubes are widely used in clinical fields, disease control fields, strain preservation centers, and pharmaceutical companies.

[0003] For normal use of cryotubes, most of them are carried and stored in test kits, that is, the cryotubes are placed vertically in the holes of the test kit and can be directly taken out when they are used. However, for current test kits and other carriers, in order to improve the utilization rate when storing cryotubes, the density of the holes is relatively high, which makes the top screw caps of the cryotubes closer when stored, and the top surfaces of the screw caps of the cryotubes are flat when stored, which makes it difficult for people's fingers to reach into the gaps between the screw caps to take out the cryotubes.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a freezing tube bearing structure, including a frame body 1 and a top cover 2, the top cover 2 is installed on the top of the frame body 1, a plurality of bearing plates 3 are equidistantly and parallelly arranged on the top of the frame body 1, a receiving groove 4 is formed between two adjacent bearing plates 3, a base 5 is arranged above the receiving groove 4, the side walls of the two adjacent bases 5 are fitted together, a hole 6 for storing freezing tubes is arranged on the top of the base 5, a lifting mechanism is arranged between the base 5 and the frame body 1, a ventilation groove 20 is arranged on the bottom and both sides of the frame body 1, and an inclined supporting leg 21 is fixedly arranged on the bottom of the frame body 1.

[0024] See also Figure 1 and 2 , the cryotube is placed in the hole 6. In order to reduce the overall volume, the gap between the screw caps on the tops of two adjacent cryotubes is small. When taking the cryotube, the base 5 where the cryotube is located is lifted as a whole by the lifting mechanism. At this time, the height of all the cryotubes on the base 5 will be higher than the height of other cryotubes, and the staff can directly take the cryotube with their fingers. In this embodiment, the support legs 21 can be set to lift the frame 1 as a whole, so that the frame 1 can not directly contact the desktop or other planes, thereby preventing contamination of the cryotube.

[0025] The lifting mechanism includes a rotating shaft 7, a driving shaft 8, a lifting seat 9 and a connecting sleeve 10. The lifting seat 9 is fixedly arranged at the bottom of the base 5, and the lifting seat 9 is just engaged in the accommodating groove 4. The bottom of the base 5 is in contact with the top of the bearing plate 3. The connecting sleeve 10 is fixedly arranged at the center position of the bottom of the lifting seat 9. The rotating shaft 7 is rotatably arranged on the inner wall of the frame 1, and the driving shaft 8 is rotatably arranged at the bottom of the frame 1. One end of the rotating shaft 7 is connected to the driving shaft 8 through a transmission member, and the top of the driving shaft 8 is connected to the connecting sleeve 10 through a driving member. The driving member includes a guide groove 11 and a guide protrusion. 12, the guide groove 11 is arranged on the inner wall of the connecting sleeve 10, there is a height difference between the top and bottom ends of the guide groove 11, the guide protrusion 12 is arranged on the surface of the driving shaft 8, and the guide protrusion 12 is engaged with the top of the guide groove 11, the guide groove 11 is spirally distributed on the inner wall of the connecting sleeve 10, and the projection of the guide groove 11 on the end face of the connecting sleeve 10 is an arc with a central angle of 180°, the transmission member includes a first bevel gear 13 fixed on the driving shaft 8 and a second bevel gear 14 fixed at one end of the rotating shaft 7, and the first bevel gear 13 and the second bevel gear 14 are meshed with each other.

[0026] See also Figure 3 , 4 and 5. After rotating the rotating shaft 7, the rotating shaft 7 can drive the second bevel gear 14 to rotate. At this time, the second bevel gear 14 can drive the driving shaft 8 to rotate through the first bevel gear 13. When the driving shaft 8 rotates, it can drive the guide protrusion 12 to rotate synchronously. However, since the connecting sleeve 10 is fixed, when the guide protrusion 12 rotates, the guide protrusion 12 will exert a vertical upward force inside the guide groove 11, and then push the connecting sleeve 10 up through the guide groove 11, so that the connecting sleeve 10 drives the base 5 to move up synchronously through the lifting seat 9. When the guide protrusion 12 rotates 180°, the guide protrusion 12 moves from the top end of the guide groove 11 to the bottom end. At this time, the lifting seat 9 drives the base 5 to move up to the highest point.

[0027] A reset mechanism is provided between the rotating shaft 7 and the frame 1, and the reset mechanism includes a torsion spring 15 and a knob 16. The knob 16 is fixed to one end of the rotating shaft 7, the torsion spring 15 is sleeved on the surface of the rotating shaft 7, and the two ends of the torsion spring 15 are respectively fixed to the knob 16 and the surface of the frame 1.

[0028] See also Figure 3In the above process, the rotation of the rotating shaft 7 is manually driven by the staff through the knob 16. Therefore, when the rotating shaft 7 is rotating, the torsion spring 15 can be driven to deform and store energy through one end of the knob 16. For the first bevel gear 13 and the second bevel gear 14, this embodiment sets the transmission ratio of the two to 1, which means that when the guide protrusion 12 rotates 180°, the knob 16 also needs to rotate 180°. At this time, the deformation degree of the torsion spring 15 is the largest, and the accumulated energy is also the largest. After releasing the knob 16, the torsion spring 15 releases energy to drive the rotating shaft 7 to reset. Under the action of the first bevel gear 13 and the second bevel gear 14, the drive shaft 8 can be driven to reset, thereby resetting through the cooperation of the guide groove 11 and the guide protrusion 12 and the gravity of the lifting seat 9, the base 5 and the cryopreservation tube as a whole.

[0029] A first area 17 is formed between the long sides of the two outermost bases 5 and the supporting plate 3, a second area 18 is formed between the short sides of the multiple bases 5 and the supporting plate 3, a third area 19 is formed between the short side of each base 5 and the corresponding lifting seat 9, and the bottom of the top cover 2 is in contact with the first area 17, the second area 18 and the third area 19 at the same time.

[0030] See also Figure 1 The widths of the first area 17, the second area 18 and the third area 19 are all the same, so that when the top cover 2 is installed on the frame 1, its outer surface can be exactly flush with the side of the frame 1, and the inner wall of the top cover 2 can contact the side walls of multiple bases 5. At this time, there will be no large gap between the top cover 2 and the base 5, so that the top cover 2 can protect the base 5 and the cryopreservation tubes inside it.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
