Description

Technical Field

[0001] The utility model relates to the field of environmental monitoring quality control, in particular to a weighing work cabinet for constant weight of environmental monitoring quality control samples. Background Art

[0002] In environmental testing organizations, most atmospheric environment testing laboratories lack sample processing conditions in a constant temperature and humidity environment. Differences in environmental humidity and temperature may cause measurement errors in samples. Therefore, when monitoring the environment, it is necessary to ensure that the objects to be tested are weighed inside a cabinet at a suitable temperature.

[0003] The existing weighing cabinet needs to be opened manually, and the sample objects to be tested are placed in the working cabinet for weighing. The cabinet door is opened manually, the samples are placed in for weighing, and then taken out again. In this way, the air enters and exits the cabinet for a long time, which can easily cause unstable temperature and humidity. Frequent opening of the cabinet door may result in greater weighing errors. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a weighing work cabinet for constant weight of quality control samples for environmental monitoring includes a cabinet 1 and an electronic balance 101. A feeding structure 2 is installed at the upper end of the cabinet 1. The feeding structure 2 includes a bracket 3, and a cylinder 4 is installed at the upper end of the bracket 3. A guide cylinder 5 is installed on the inner wall of the upper end of the cabinet 1, and a carrying cylinder 6 is installed at the output end of the cylinder 4. A motor 7 is installed at the upper end of the carrying cylinder 6, and a clamping rod 8 is installed on the outer wall of the output shaft of the motor 7. The clamping rod 8 consists of two arc rods and a vertical rod.

[0024] In this embodiment, a sealing gasket 9 is installed on the inner wall of the clamping rod 8 .

[0025] The sealing gasket 9 is used to ensure that the clamping rod 8 is firmly in contact with the sample storage bottle.
