Liquid nitrogen biological container bottom sample leak-proof net

Abstract

The application relates to a liquid nitrogen biological container bottom sample leakage prevention net and belongs to the technical field of biological experiment equipment. The net can conveniently take out the dropped cryopreservation tube sample from the bottom of a liquid nitrogen biological container, has good comprehensive practicability, and comprises a leakage prevention net main body, a partition column plate, a plurality of leakage prevention nets, a lifting component and a buffer protection device. The partition column plate is fixedly installed in the leakage prevention net main body and divides the leakage prevention net main body into a plurality of leakage prevention partitions. The plurality of leakage prevention nets are arranged in the leakage prevention partitions respectively, the edges of the leakage prevention nets are upwardly folded, and the edges are fixedly connected with the leakage prevention net main body and the partition column plate respectively. The lifting component is arranged on the leakage prevention net main body and is used for driving the leakage prevention net main body to lift. The buffer protection device is arranged in each leakage prevention partition and is located above the leakage prevention net and is fixedly connected with the leakage prevention net. The edge stabilizing mechanism is uniformly arranged on the outer periphery of the leakage prevention net main body in the circumferential direction and is used for keeping the leakage prevention net main body stable during lifting and relieving liquid nitrogen flow force impact.
