AI Technical Summary
Existing refrigerated storage boxes lack effective restraint measures when carrying filter membrane cartridges, making the cartridges prone to bumps, shaking, or inversion during transportation, affecting the integrity of the samples and the reliability of the analysis results.
A rotary clamping limit mechanism and shock-absorbing pads are installed in the drawer compartment of the refrigerated storage box. The limit mechanism stabilizes the filter membrane box through springs and limit blocks, while the shock-absorbing pads absorb external forces through sponge or foam material, providing cushioning protection.
It effectively prevents the filter membrane box from being bumped or inverted during transportation, improves storage stability, ensures the safety of the filter membrane box and the integrity of the sample, and reduces the risk of damage.
