Abstract

The invention discloses a high-precision weighing device for a test box. The device comprises a bottom plate; guide slide wheels matched with guide slide rails are fixedly mounted on the lower surfaces of each of supporting legs respectively; a connecting plate is fixedly mounted on the outer sides of the two supporting legs on the right side of the bottom plate; a connecting shell is fixedly mounted at one side of the connecting plate; two limiting holes are formed in the outer side of the connecting shell; a movable rod connected with a damping base is arranged in the connecting shell; a mounting groove is formed in the outer side of the movable rod; a reset spring is fixedly mounted at the inner side of the mounting groove; and one end of the reset spring is fixedly connected with a protruding block corresponding to the limiting holes. According to the high-precision weighing device for the test box of the invention, the connecting shell and the movable rod are adopted; the total length of the connecting shell and the movable rod is adjusted by controlling a position relation between the protruding block and the limiting holes, so that a distance between an accessory cabin and aweighing cabin is fixed; the arms of a user will not be clamped and harmed by the accessory cabin and the weighing cabin, and therefore, safety is high.

Description

technical field [0001] The invention relates to the technical field of detection and weighing equipment for ambient air and fixed pollution source particles, in particular to a high-precision weighing device for a test chamber. Background technique [0002] With the frequent occurrence of dust storms and smog weather, the air pollution problem has attracted more and more people's attention. The detection of air quality is also particularly important. The monitoring, analysis and research of particulate matter in the air is the focus of current environmental protection work. At present, the commonly used monitoring methods include light transmission method, laser backscattering method, charge method, β-ray absorption method, filter weighing method, etc. Among them, the filter weighing method is the most widely used one at present. Its basic principle is that a certain volume of dust-containing gas passes through a filter membrane of known weight, and the dust particles in th...
