Sample conveying tray for chemical examination

Abstract

The invention discloses a sample conveying tray for chemical examination and relates to the technical field of trays. The tray comprises a tray body and a tray cover, wherein the tray body comprises abox body, a supporting plate is arranged on the box body through a plurality of supporting columns, and a plurality of through holes for placing test tubes are formed in the supporting plate; two sides of the box body are provided with first flanges which are folded outwards, the upper surface of each first flange is provided with a side plate which is vertically arranged, and each side plate isprovided with a second flange which is folded outwards. The bottom side surface of the flange I is provided with an L-shaped flange which is folded towards the inner side; the tray cover comprises a cover body covering the box body, and a test tube sleeve covering the top of the test tube is arranged on the side face of the inner top of the cover body. The tray cover is arranged on the box body, and the test tube sleeve is arranged on the side surface of the inner top of the tray cover, so that convection between the interior of a test tube and air is reduced by utilizing the box body, the tray cover and the test tube sleeve in a sample feeding process, and the tray cover is opened in an inspection process, thereby being convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of trays, in particular to a sample delivery tray for chemical testing. Background technique [0002] In the fields of medical treatment, cosmetics production, chemical experiments, biological experiments, etc., sampling and testing are often required. The existing sampling process mostly uses test tubes as storage containers for liquid samples. After the samples are collected through the test tubes, the test tubes are sent for inspection The existing test tube rack is simple in structure and poor in stability. At the same time, the inside of the test tube is easy to form convection with the air during the moving process, resulting in a decrease in the accuracy of the sample; The sealing plug at the end of each test tube needs to be opened, and the sealing plug needs to be cleaned and dried after each use, so as to avoid contamination of the liquid sample in the test tube by the substance contaminated by the...
