Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a sampling equipment for chemical detection. Background Art

[0002] Chemistry is a basic natural science that studies the composition, structure, properties, transformations, and applications of matter at the atomic and molecular levels. It originates from life and production practices and continues to develop with the progress of human society. Unlike particle physics and nuclear physics, which study smaller scales, chemistry studies the material structure, chemical bonds, intermolecular forces, and other interactions of atoms, molecules, and ions (clusters). The scale at which it studies is the closest to the macroscopic in the microscopic world, and therefore its natural laws are most closely related to the physical and chemical properties of matter and materials in the macroscopic world in which humans live. During chemical testing, liquid samples are sampled using sampling equipment.

[0003] A Chinese patent application (CN202223331416.0) discloses a chemical detection sampling device, which is small in size and easy to carry by providing a shell, a liquid storage tank, a scale line, a handheld mechanism and a piston assembly. The device generates negative pressure by moving the piston to achieve water sampling. However, when the existing chemical detection sampling equipment is used, after sampling a liquid, it is impossible to sample other liquids. A new sampling equipment needs to be replaced, otherwise the sample will be mixed and cannot be used, resulting in low sampling efficiency. Therefore, a sampling device for chemical detection is proposed. Summary of the Invention

One end of the rotating shaft 18 is fixedly connected to the partition frame 14. One side of the partition frame 14 is evenly distributed with card slots 16, and one side of the partition frame 14 is evenly distributed with limiting slots 17. A disposable sampler 25 is provided inside the card slot 16, so that the disposable sampler 25 is separated and loaded into the partition frame 14. One side of the disposable sampler 25 is engaged with the limiting slot 17. The limiting slot 17 prevents the disposable sampler 25 from shifting up and down. The partition frame 14 cooperates with the storage tube 11 to prevent the disposable sampler 25 from shifting horizontally. In order to facilitate the disassembly and assembly of the disposable sampler 25, a cover plate 13 is hinged on one side of the storage tube 11.

[0029] In this embodiment, specifically: in order to prevent different liquid samples from mixing, a socket 12 is opened on one side of the storage tube 11, and a sampling needle 24 is inserted into the interior of the socket 12. One side of the sampling needle 24 is engaged with the disposable sampler 25, which facilitates the disassembly and replacement of the sampling needle 24, so that different disposable samplers 25 use different sampling needles 24.
