[0030] Specifically, the stabilizing device 7 is symmetrically arranged as a whole, and the stabilizing shell 72 arranged inside the stabilizing device 7 is connected to the left and right sides of the connecting shell 61, ensuring that the stabilizing devices 7 arranged on both sides can achieve stable support and stable movement cooperation for the first freezing tube rack 4; the spring 75, the stop block 76 and the first guide groove 77 are all symmetrically arranged front to back, and the stop block 76 is slidably embedded in the first guide groove 77, ensuring that the stop block 76 cooperates with the first guide groove 77 to achieve efficient and stable movement cooperation; the roller 78 and the second guide groove 79 are symmetrically arranged left to right, and the roller 78 is rotatably built into the left and right sides of the connecting frame 73, ensuring that the roller 78 can assist in achieving rolling cooperation and enhance the smoothness of movement and adjustment.

[0031] Here’s how it works:

[0032] When the present cell cryopreservation tube rack box is to be used, the top cover 3 connected to the upper end of the box body 1 can be opened to expose the first cryopreservation tube rack 4 and the second cryopreservation tube rack 5 provided inside. In this way, the staff can insert the cryopreservation tubes storing cells between the first cryopreservation tube rack 4 and the second cryopreservation tube rack 5, so that the first cryopreservation tube rack 4 and the second cryopreservation tube rack 5 can realize the stable receiving and placing cooperation of the cryopreservation tubes. Finally, by re-placing the top cover 3 on the upper end of the box body 1, the sealing and closing activity can be realized, and the influence of moisture on the bacteria stored inside can be reduced. The handles 2 provided on the left and right sides of the upper end of the box body 1 can realize the convenient carrying and transporting activity.

[0033] In order to enhance the adaptability of the present cryopreservation tube rack box, a size adjustment device 6 is provided at the rear side of the box body 1, that is, by pushing the pushing end provided at the upper end of the right-side card strip 64 to the right, the right-side card strip 64 moves to the right accordingly. When the right-side card strip 64 moves to the right, the first rack 68 laterally connected to the top can be driven. In this way, the gear 69 meshing with the upper end of the first rack 68 will rotate counterclockwise to drive the second rack 610 meshing at the top, so that the second rack 610 realizes the leftward movement of the left-side card strip 64 accordingly. In this way, the card strips 64 on both sides installed at the vertical grooves on both sides of the leftward movement of the fastening plate 62 can realize opposite lateral movement to release the two The plug-in end of the side clamping strip 64 has a plug-in locking effect on the slider 63. At the same time, when the clamping strips 64 on both sides move in opposite directions, the external horizontal plug-in rod 65 and the connecting plate 66 are pushed, so that the connecting plate 66 cooperates with the fixed rod 67 plugged in on the other side to achieve mobile support cooperation, and the compression spring 611 provided on the outside of the fixed rod 67 is compressed. When the clamping strips 64 on both sides are synchronously moved out of the fastening plate 62, the first cryogenic tube rack 4 can be released from the locking effect, and can be moved up and down along the front side of the connecting shell 61 to adjust the appropriate position, and efficiently cooperate with the second cryogenic tube rack 5 to achieve stable placement of different cryogenic tubes.

[0034] When the spacing between the first cryogenic tube rack 4 and the second cryogenic tube rack 5 is adjusted, the right clamping strip 64 can be loosened to allow the compressed compression spring 611 outside the right fixing rod 67 to rebound, so as to automatically push the right clamping strip 64 to the left, and the left-moving right clamping strip 64 can cooperate with the meshing transmission of the first rack 68, the gear 69 and the second rack 610 to realize the rightward movement transmission of the left clamping strip 64. In this way, the clamping strips 64 on both sides can move relatively synchronously to move back into the fastening plate 62, and the slider 63 that has completed the adjustment activity can be plugged in and locked to ensure that the slider 63 is in a locked state, thereby ensuring that the spacing between the first cryogenic tube rack 4 and the second cryogenic tube rack 5 can be kept in a stable receiving state after the spacing is adjusted, thereby achieving the advantages of flexible adjustment of the cryogenic tube storage spacing to meet the placement of different cryogenic tubes;

[0035] Secondly, when the first cryopreservation tube rack 4 is moved up and down for adjustment, in order to ensure the stability and smoothness of the movement process, a stabilizing device 7 is also provided on the left and right sides of the size adjusting device 6, that is, during the up and down movement of the first cryopreservation tube rack 4, the fastening strips 71 fastened on the left and right sides will be synchronously driven to move, and the connecting frame 73 installed at the rear side of the fastening strips 71 and built into the stabilizing shell 72 will realize the movement guidance and stable cooperation along the guide plate 74 inserted inside, so that the first cryopreservation tube rack 4 moves smoothly and stably, and the springs 75 and the stop blocks 76 provided at the front and rear of the connecting frame 73 are cooperated. The elastic offset effect of the first guide groove 77 opened in front and behind the guide plate 74 can enhance the connection stability between the connecting frame 73 and the guide plate 74, and further ensure the movement stability of the first cryogenic tube rack 4. Secondly, rollers 78 are installed inside the left and right sides of the connecting frame 73 to roll with the second guide grooves 79 opened on the left and right sides of the guide plate 74, so as to enhance the movement smoothness of the connecting frame 73, reduce the movement jamming effect, and enable the first cryogenic tube rack 4 to achieve smooth movement and adjustment as a whole, thereby achieving the advantages of enhanced movement and adjustment stability and smoothness of the first cryogenic tube rack 4.

[0036] The utility model provides a cell freezing tube rack box, which is provided with a size adjustment device 6, that is, when the clamping strip 64 provided on one side moves, the first rack 68, the gear 69 and the second rack 610 can be meshed and transmitted to realize the synchronous movement of the clamping strip 64 provided on the other side. In this way, when the clamping strips 64 provided on both sides move synchronously relative to or oppositely, the slider 63 can be quickly locked or unlocked, so that the first freezing tube rack 4 can be conveniently moved up and down for adjustment, and the receiving spacing can be changed to meet the requirements of placing different freezing tubes, thereby achieving the advantages of flexible adjustment of the freezing tube storage spacing to meet the requirements of placing different freezing tubes, and a stabilizing device 7 is provided, that is, the connecting frame 73 can be in a stable movement with the guide plate 74, and the combination of the spring 75, the stop block 76, the first guide groove 77 and the roller 78, the second guide groove 79 can enhance the adjustment stability and smoothness, thereby achieving the advantages of enhanced movement adjustment stability and smoothness of the first freezing tube rack 4.
