[0031] Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 lies in that: Specifically, the fixing component 6 includes a test tube rack 61, a holding rack 62, an adjusting component 63, a placement groove 64, a telescopic seat 65, a spring rod 66 and a clamping plate 67. Among them, a holding rack 62 is arranged on the surface of the fixing rod 7, a test tube rack 61 is arranged above the holding rack 62, an adjusting component 63 is arranged between the test tube rack 61 and the holding rack 62, a placement groove 64 is arranged in the middle of the test tube rack 61, a clamping plate 67 is arranged in the middle of the placement groove 64, a telescopic seat 65 is arranged on one side of the clamping plate 67, and spring rods 66 are arranged on both sides of the telescopic seat 65.

[0033] By adopting the above technical solution, when it is necessary to freeze a biological sample, the test tube is placed into the placement groove 64. After the test tube is placed into the placement groove 64, the clamping plate 67 in the middle will clamp it through the rebound of the spring rod 66, so that the test tube rack 61 can fix test tubes with different diameters. Since a holding rack 62 is arranged below the test tube rack 61, the bottom of the test tube can be supported, and an adjusting component 63 is arranged between the test tube rack 61 and the holding rack 62, so that the test tube rack 61 can be adjusted according to the length of the test tube.

[0034] Specifically, the adjusting component 63 includes a handwheel 631, a slider 632, an adjusting screw 633 and a rotating base two 634. Among them, a slider 632 is arranged at one end of the test tube rack 61, an adjusting screw 633 is arranged between the test tube rack 61 and the holding rack 62, a rotating base two 634 is arranged at one end of the adjusting screw 633, and a handwheel 631 is arranged at the other end of the adjusting screw 633.

[0035] By adopting the above technical solution, after the test tube is placed into the test tube rack 61, rotate the handwheel 631 to drive the adjusting screw 633 to rotate. After the adjusting screw 633 rotates, the test tube rack 61 will move up and down, so that the staff can adjust the test tube rack 61 according to the length of the test tube.

[0036] Specifically, a chute is arranged on the surface of the fixing rod 7, and the test tube rack 61 is connected to the chute through the slider 632.

[0037] By adopting the above technical solution, a chute is arranged on the surface of the fixing rod 7, and the test tube rack 61 is connected to the chute through the slider 632, so that the staff can control the test tube rack 61 to move up and down by rotating the adjusting screw 633.

[0038] When this embodiment is in use, when it is necessary to freeze a biological sample, the test tube is placed into the placement groove 64. After the test tube is placed into the placement groove 64, the clamping plate 67 in the middle will clamp it through the rebound of the spring rod 66, so that the test tube rack 61 can fix test tubes of different calibers. Since a supporting rack 62 is arranged below the test tube rack 61, the bottom of the test tube can be supported. And an adjusting assembly 63 is arranged between the test tube rack 61 and the supporting rack 62. After the test tube is placed into the test tube rack 61, turning the hand wheel 631 drives the adjusting screw rod 633 to rotate. After the adjusting screw rod 633 rotates, the test tube rack 61 will move up and down, so that the staff can adjust the test tube rack 61 according to the length of the test tube.

[0039] In the present utility model, the damper 31 is a publicly known technology, and the selected model is ZTE-1.

[0040] In the present utility model, the telescopic rod 32 is a publicly known technology, and the selected model is FRGSS100-400.

[0041] The structure and working principle of the freezer cabinet body 1 of the present utility model have been disclosed in a biological sample freezing storage device disclosed in Chinese Patent Publication No. CN216592382U.

[0042] The working principle and usage process of the present utility model: When the present utility model is in use, the freezer cabinet for storing biological samples moves. When transporting biological samples, it is necessary to push the freezer cabinet body 1 to move. Universal wheels 37 are arranged below the freezer cabinet body 1, so that the freezer cabinet body 1 can be pushed to move, which is convenient for the staff to transport the biological samples in the cabinet. When it is necessary to move the freezer cabinet body 1, reverse the threaded rod 35 to drive the fixed block 36 to rise. After the fixed block 36 rises, push the freezer cabinet body 1 to move through the handle 4. When the freezer cabinet body 1 moves to the corresponding position, rotate the threaded rod 35 to drive the fixed block 36 to descend, so as to fix the freezer cabinet body 1. Since a telescopic rod 32 and a damper 31 are arranged between the fixed seat 33 and the freezer cabinet body 1, the freezer cabinet body 1 during movement can be shock-absorbed. And the damper 31 and the telescopic rod 32 are arranged between the freezer cabinet body 1 and the fixed seat 33 through fixing bolts, which is convenient for the staff to install;

[0043] In use, for the tube fixation of the refrigeration and freezing device for storing biological samples, when the biological sample is frozen, tubes of different calibers need to be fixed. When the biological sample needs to be frozen, the tube is placed in the placement groove 64. After the tube is placed in the placement groove 64, the clamping plate 67 in the middle will clamp it through the rebound of the spring rod 66, so that the test tube rack 61 can fix tubes of different calibers. Since a support rack 62 is provided below the test tube rack 61, the bottom of the tube can be supported. And an adjustment assembly 63 is provided between the test tube rack 61 and the support rack 62. After the tube is placed in the test tube rack 61, turning the hand wheel 631 drives the adjustment screw rod 633 to rotate. After the adjustment screw rod 633 rotates, the test tube rack 61 will move up and down, so that the staff can adjust the test tube rack 61 according to the length of the tube.
