Abstract

The invention discloses a sample preservation device for animal and plant quarantine experiments, and relates to the technical field of experimental sample preservation. The sample preservation device comprises a cylinder, an assembly cover and a sample loading assembly, the assembly cover is clamped to the top end of the cylinder, a piston fixing assembly is fixedly mounted on the inner wall of the top of the assembly cover, a built-in end plate is fixedly installed at the end, close to the top, of the cylinder, through grooves which are evenly distributed are formed in the built-in end plate, metal clamping cylinders are fixedly installed on the inner walls of the through grooves, heat exchange assemblies are installed on the outer walls of the circumferences of the metal clamping cylinders, bottom springs are fixedly installed in the metal clamping cylinders, and a bottom frame seat is fixedly mounted at the bottom end of the cylinder. According to the piston fixing assembly, an arranged compression spring can be used for pushing an abutting ring, and the abutting ring is clamped into a clamping ring groove in the top end of each piston block, so that each piston block can be independently and effectively fixed, and the piston blocks are prevented from bumping and being separated from a sample loading pipe in the transportation process.

Description

technical field [0001] The invention discloses a sample storage device for animal and plant quarantine experiments, and relates to the technical field of experimental sample storage. Background technique [0002] In order to prevent animal infectious diseases, parasitic diseases and dangerous plant diseases, insects, weeds and other harmful organisms from being introduced into and out of the country, and to protect agriculture, forestry, animal husbandry, fishery production and human health, it is necessary to quarantine the entry and exit animals and plants . In the process of animal and plant quarantine, it is often necessary to use a sample preservation and transportation device, and set a foam layer at the bottom of the test tube containing the sample for buffer protection. [0003] However, the existing sample storage device still has the following disadvantages. First, the existing sample storage device generally uses springs to cooperate with the pressing plate to si...
