The process of transferring the sample cartridge from the sample storage rack 9 to the docking mechanism 1 is as follows: the rotary motion driving mechanism 4 drives the transfer mechanism 2 to rotate so that the transfer mechanism 2 faces the sample storage rack 9, i.e., so that the sample temporary storage space of the transfer mechanism 2 is opposed to the sample placement space of the sample storage rack 9; the transfer mechanism 2 reciprocates once forward and backward in a direction perpendicular to the vertical direction with respect to the sample storage rack 9 under the drive of the horizontal movement drive mechanism 3 to transfer the sample cartridge in the sample placing space into the sample temporary storage space; then the transfer mechanism 2 is driven by the rotary motion driving mechanism 4 to rotate, so that the transfer mechanism 2 faces the docking mechanism 1, namely, the sample temporary storage space of the transfer mechanism 2 is opposite to the external docking space of the docking mechanism 1; then the transfer mechanism 2 reciprocates forward and backward relative to the docking mechanism 1 in a direction perpendicular to the vertical direction once under the driving of the horizontal movement driving mechanism 3 to transfer the sample cartridge located in the sample temporary storage space into the external docking space, that is, transfer the sample cartridge onto the docking mechanism 1, so that the user can further take the sample cartridge out of the biological sample storage device.

When the output shaft of the first motor 41 rotates, the transfer mechanism 2 and the horizontal movement drive mechanism 3 are driven to rotate along the axis parallel to the vertical direction.

The first motor 41 is configured to drive the transfer mechanism 2 and the horizontal movement driving mechanism 3 to rotate along an axis parallel to the vertical direction, so that the sample placing space of the transfer mechanism 2 can be respectively opposite to the sample placing space of the sample storage rack 9 and the external docking space of the docking mechanism 1. The connection mode of the first motor 41, the transfer mechanism 2 and the horizontal movement driving mechanism 3, and the power of the first motor 41 are not limited, and can be set accordingly according to the actual application requirements.

Further, the output shaft of the first motor 41 may be directly or indirectly connected to the transfer mechanism 2 and the horizontal movement driving mechanism 3. For example, the output shaft of the first motor 41 may be directly connected to the transfer mechanism 2 and the horizontal movement drive mechanism 3, respectively; the transfer mechanism 2 can also be connected with the output shaft of the first motor 41 and the horizontal motion driving mechanism 3; or the horizontal motion driving mechanism 3 is connected with the output shaft of the first motor 41 and the transfer mechanism 2; alternatively, the output shaft of the first motor 41 is indirectly connected to the transfer mechanism 2 and the horizontal movement driving mechanism 3 through the mounting mechanism.

In addition, the installation position of the code scanning mechanism is not limited, but it is required to ensure that the code scanning mechanism can read and obtain the barcode information on the sample cartridge when the sample cartridge is located in the external docking space of the docking mechanism 1.

Optionally, in order to increase the number of sample cartridges that can be placed, at least two sample supports with different heights are vertically disposed on the sample storage rack 9, and a sample placing space for placing the sample cartridges is disposed on each sample support.

Among them, because among the prior art, if the sample box stacks up from top to bottom in refrigerator 8, when will be followed the top of sample box and will be located a certain sample box on top layer and take out, need earlier to shift the sample box that is located its top in proper order, just can take out this sample box, lead to the inefficiency of taking out of sample box. This embodiment is through setting up elevating system 5, when elevating system 5 is connected with sample storage rack 9, elevating system 5 can drive sample storage rack 9 and remove along vertical direction for transfer mechanism 2, thereby can place the high position adjustment in space to the high position with transfer mechanism 2 butt joint with a sample in sample storage rack 9, be about to the sample place the space highly and sample in vertical direction and keep in the space adaptation, with further place the space with the sample from the sample through transfer mechanism 2 and shift the sample to sample temporary storage space, perhaps shift the sample box to the sample from sample temporary storage space and place the space.

In addition, the specific structure, shape and size of the lifting mechanism 5 and the connection mode of the lifting mechanism 5 and the sample storage rack 9 are not limited, and can be set correspondingly according to the actual application requirements. For example, the lifting mechanism 5 and the sample storage rack 9 may be fixedly connected, and the lifting mechanism 5 and the sample storage rack 9 may be detachably connected.

Further, in order to increase the number of sample cartridges that can be stored in the biological sample storage apparatus, a plurality of sample storage racks 9 may be provided, and one or more sample placing spaces may be provided on each sample storage rack 9. When the number of the sample storage racks 9 is plural, in order to simplify the structural complexity of the elevating mechanism 5, it is preferable that the elevating mechanism 5 is detachably connected to all the sample storage racks 9.

Further, in consideration of the fact that different sample storage racks 9 may be placed at different horizontal positions in the low-temperature storage space of the refrigerator 8, that is, different horizontal positions of the different sample storage racks 9 on a plane parallel to the horizontal plane, the horizontal position of the sample storage rack 9 with respect to the elevating mechanism 5 may be adjusted by providing the adjusting mechanism 6 for adjusting the horizontal position so that the horizontal position of the target rack is located at a position where the target rack can be connected to the elevating mechanism 5, that is, the target rack is located at a horizontal position where the elevating mechanism 5 is connected to the elevating mechanism, so that the elevating mechanism 5 can be connected to the target rack by further movement.
