AI Technical Summary

Technical Problem

Existing biological sample cold storage boxes have low space utilization and cumbersome limiting operations, requiring multiple adjustments of the screw to achieve the limiting effect, resulting in low usage efficiency.

Method used

The design incorporates a multi-layered placement plate and a dual limiting mechanism, including a first limiting component and a second limiting component. The first limiting component achieves side clamping through a clamping block and a baffle, while the second limiting component achieves top compression through a squeezing plate and an elastic sheet. Combined with a temperature detector and a control panel, this ensures stable sample storage.

Benefits of technology

It improves the utilization rate of the chamber space, simplifies the limiting operation, prevents sample shaking, ensures the safety of biological samples, and can monitor and adjust the temperature in real time, thus improving the ease of use and efficiency.

Abstract

This utility model discloses a biological sample cold storage box, relating to the field of sample storage technology. It includes a box body and a door. A placement plate is fixedly installed inside the box body. Several placement slots are evenly distributed on the upper surface of the placement plate. An installation slot is provided at the bottom of the box body, and an ice box slides within the installation slot. A limiting mechanism is provided at the upper end of the placement plate to prevent sample vessels from shaking. The limiting mechanism includes a first limiting member and a second limiting member. The first limiting member is used to adapt to sample vessels of different sizes, and the second limiting member is used to compress the top of the sample vessels. This utility model improves the actual utilization rate of the box space through multiple placement plates. Turning the handle drives the screw to rotate, causing multiple clamping blocks to slide synchronously along the guide rod, cooperating with the baffle to clamp and limit sample vessels of different sizes. A temperature detector is provided to monitor the internal temperature in real time, allowing users to intuitively understand temperature changes within the box.
