Abstract

The invention relates to the technical field of biological medical instruments, and particularly discloses a rotating mechanism for a freeze-storage tube cover screwing. The mechanism comprises a first rotating rod, a first fixing block, a first rotating column, a second rotating rod, a second fixing block and a second rotating column, a second chain wheel is arranged at the upper end of the firstrotating rod, the second rotating column is located below the first rotating column, the first rotating column is connected with the second rotating column through a plurality of transmission pieces,the lower end of the second rotating rod is movably sleeved with a cover screwing head through an adjusting mechanism, cover screwing openings matched with the tube cover of the freeze-storage tube in shape is formed in the cover screwing head, a first spring is arranged at the position, located between the second rotating column and the cover screwing head, of the second rotating rod, the two cover screwing openings are located right above clamping positions of two clamping grooves, a plurality of mounting holes are formed in the first rotating column in the axial direction, and the transmission pieces are arranged in the mounting holes. The mechanism has the characteristics that the cover screwing efficiency is relatively high, the labor cost is relatively low, the screwing effect is relatively good, and the application range is relatively wide.

Description

technical field [0001] The invention relates to the technical field of biomedical devices, in particular to a rotating mechanism used for capping cryopreservation tubes. Background technique [0002] Cryopreservation tube is a disposable medical vessel commonly used in medical and laboratory research to store biological samples. In the era of translational medicine, a large number of biological sample banks began to be built. Personalized diagnosis and precise treatment for each person require biological samples. Long-term ultra-low temperature storage, low temperature storage can keep biological tissues such as blood, stem cells, and immune cells active for a long time. When storing, biological samples need to be submerged in a suitable freezing medium (such as liquid nitrogen). At present, the commonly used containers for storing biological samples are cryopreservation tubes. There are two types of storage tubes. In order to make the cryopreservation tube have good sealin...
