[0028] See also Figures 1 to 6 The utility model provides a technical solution: a sample storage box.

[0029] In the first embodiment, a mounting hole 6 is provided on one side surface of the box cover 1, and a storage groove 8 is provided on the same side surface of the box cover 1. A spring 9 is fixed on the inner wall surface of the storage groove 8, and a limit block 4 is provided on the inner wall surface of the storage groove 8. Due to the elasticity of the spring 9, the spring 9 will reset and hold the baffle 15 to make the limit block 4 disengage from the storage groove 8, so that the limit tooth groove 16 is re-engaged with the limit gear 2, and the limit gear 2 is limited, so that the box cover 1 is fixed to the outer surface of the sample storage box body 3;

[0030] A transmission tooth groove 10 is provided on the side surface of the sample preservation box body 3, and a transmission gear 14 is provided on the same side surface of the sample preservation box body 3. When the box cover 1 moves on the outer surface of the sample preservation box body 3, the transmission tooth groove 10 will drive the transmission gear 14 to rotate, and the rotation of the transmission gear 14 will drive the limit gear 2 to rotate. A guide rod 13 is inserted and fixed at the end of the transmission gear 14, and the limit gear 2 is fixed at one end of the guide rod 13.

[0031] On the basis of embodiment 1, in order to adjust the height of the sample preservation box body 3, a through groove 5 and an annular groove 7 are provided on the arc surface of the inner wall of the mounting hole 6, the through groove 5 penetrates the inner surface of the box cover 1, a notch 11 is provided at the end of the storage groove 8, and a baffle 15 is provided on the inner surface of the notch 11.

[0032] The baffle 15 has a limit block 4 fixed on its surface, a limit tooth groove 16 is provided on the limit block 4 surface, an annular block 12 is fixed on the arc surface at both ends of the guide rod 13, and a transmission gear 14 is fixed on the arc surface of the guide rod 13 between the annular blocks 12 at both ends.

[0033] There are multiple groups of annular grooves 7, which are symmetrically distributed on the inner wall surface of the mounting hole 6. There are multiple groups of annular blocks 12, which are symmetrically distributed on the outer surface of the guide rod 13. The annular blocks 12 correspond to the annular grooves 7. The annular blocks 12 are clamped in the annular grooves 7. The two are movably connected and play a positioning role as the guide rod 13 rotates on the inner wall of the mounting hole 6 to prevent the guide rod 13 from escaping from the mounting hole 6.

[0034] There are multiple groups of through grooves 5, which are symmetrically distributed on the inner wall surface of the mounting hole 6, and the transmission gear 14 corresponds to the through grooves 5. The transmission gear 14 is located in the through grooves 5. The transmission gear 14 corresponds to the transmission tooth groove 10 at the same time. The transmission gear 14 is clamped with the transmission tooth groove 10 in a gear clamping manner. When the box cover 1 moves on the outer surface of the sample preservation box body 3, the transmission gear 14 will be driven to rotate through the transmission tooth groove 10, and the rotation of the transmission gear 14 will drive the limit gear 2 to rotate.

[0035] The bottom area of ​​the storage groove 8 is the same as the bottom area of ​​the baffle 15, the area of ​​the slot 11 is the same as the bottom area of ​​the limit block 4, and the bottom area of ​​the storage groove 8 is larger than the area of ​​the slot 11, and the baffle 15 corresponds to the storage groove 8, and the baffle 15 is stuck in the storage groove 8, and the two are movably connected, so the baffle 15 will not be separated from the storage groove 8, so the limit block 4 will not be completely separated from the storage groove 8.

[0036] During actual use, when the sample preservation tube is placed in the sample preservation box body 3, the limit block 4 is pressed to store the limit block 4 in the storage groove 8. At this time, the limit of the limit gear 2 disappears, and then the box cover 1 can be clamped on the outer surface of the sample preservation box body 3, and the transmission gear 14 is clamped in the transmission tooth groove 10. Then the box cover 1 is pressed to move on the outer surface of the sample preservation box body 3. When the height of the box cover 1 matches the height of the sample preservation tube, stop pressing the box cover 1 and stop pressing the limit block 4. Due to the elasticity of the spring 9, the spring 9 will reset and hold the baffle 15 to make the limit block 4 disengage from the storage groove 8, so that the limit tooth groove 16 is re-locked with the limit gear 2, and the limit gear 2 is limited, so that the box cover 1 is fixed on the outer surface of the sample preservation box body 3. This structure is simple and easy to operate, which is conducive to improving its use effect.

[0037] Although 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.
