Biological sample quality-guaranteeing storage and transportation device for genetic engineering

The invention provides a genetic engineering biological sample quality-guaranteeing storage and transportation device which comprises a liquid nitrogen tank and a damping mechanism, a placing groove is formed in the liquid nitrogen tank, a storage mechanism is arranged in the placing groove, an anti-collision mechanism is arranged outside the liquid nitrogen tank, the damping mechanism is arranged below the liquid nitrogen tank, and the damping mechanism comprises a damping groove and a connecting seat. And damping springs are fixedly mounted at the bottoms in the damping grooves. By arranging the damping mechanism, when the liquid nitrogen container bumps during transportation, a connecting seat below the liquid nitrogen container downwards extrudes a lower pressing plate, so that the lower pressing plate extrudes a damping spring, and when the bottom of the liquid nitrogen container abuts against a plastic plate on a protection plate, the damping spring starts to rebound and reciprocates back and forth, so
