A test tube wrapping device

Abstract

The invention discloses a test tube wrapping device, which comprises a base, a contraction frame and a neck ring; the top of the base is provided with a bearing chamber matching the bottom of the test tube, and the top of the bearing chamber is provided with support grooves evenly distributed along the periphery, The support groove is provided with a first through hole; the shrink frame includes a number of sticks, the ends of the sticks pass through the first through holes and are fixedly connected to the central position of the bearing chamber, and the sticks are elastic; the neck ring includes a gripper Mechanism, the second through hole and the hidden groove; the neck ring is sleeved on the shrink frame through the second through hole; the hidden groove is embedded in the neck ring; the gripping mechanism includes a telescopic rod and a deformation claw; the telescopic rod is movably connected to the neck ring, The end of the telescopic rod is fixedly connected with the deformable claws, and the deformable claws are distributed asymmetrically around the connecting part of the telescopic rod and the deformable claws; Thin slices in the direction of the ring axis. The invention can improve the paper-wrapping efficiency of the reagent tube.

Description

technical field [0001] The invention relates to the field of air environment detection, in particular to a test tube wrapping device. Background technique [0002] When analyzing PM2.5 components, it is necessary to capture the gas, and then use different reagents to dissolve and extract the components to be analyzed. ROS is a kind of free radical, and current research shows that it is the main source of damage to the human body. Due to the high reactivity of ROS, traditional offline sampling still uses manual detection of ROS content in the atmosphere, which not only requires a lot of time and labor, but also has two serious problems: 1. The operating habits of different experimental analysts and experimental There are differences in levels, which reduces the comparability of data measured by different experimenters, and even draws wrong conclusions. 2. Part of the ROS in atmospheric particulate matter is active in chemical properties and has a short lifespan, and it take...
