Abstract

The invention discloses chemical medicine sampling equipment. The equipment comprises a sampling mechanism; a positioning cylinder is in threaded connection with the top of the outer surface of the sampling mechanism; limiting ring hooks are fixedly connected to the top of the outer surface of the positioning cylinder; an auxiliary arc rod is movably connected to the top of the outer surface of the positioning cylinder and located between the limiting ring hooks; a pressing rod is movably connected to the end, away from the positioning cylinder, of the auxiliary arc rod and comprises an inner rod; a sleeve rod is movably connected to the outer surface of the inner rod; a contraction ring sleeve is arranged in the middle of the sleeve rod; the outer surface of the sleeve rod is movably connected with the positioning cylinder; and the outer surface of the contraction ring sleeve is movably connected with the positioning cylinder. The invention belongs to the technical field of chemical machinery. Internal air is removed, an internal vacuum environment is realized, the internal air is prevented from entering a chemical reagent during sampling, the reaction progress and rate of chemicals are reduced, the reaction time of operators is prolonged, and personnel and equipment are protected.

Description

technical field

[0001] The invention relates to the technical field of chemical machinery, in particular to a chemical drug sampling device. Background technique

[0002] Chemical reagents are relative standard substances for chemical research and component analysis, and are an important condition for scientific and technological progress. They are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. It can be said that they are the eyes of chemical workers. They are used in factories, schools and hospitals. Chemical reagents are inseparable from the daily work of the institute and the research institute. Sampling means selecting representative samples from the target objects.

[0003] According to Chinese patent CN207798467U, put the curved neck funnel into the funnel ring, then clamp the test tube with the test tube clamp, align the funnel opening at the lower end of the curved neck funnel with the test tube Then pour the reagent ...
