Problems solved by technology
At present, when the extraction instrument is actually used, the extraction column in the extraction instrument is placed directly on the flow control valve at the top of the extraction instrument. The contact area between the extraction column and the flow control valve is small, and there are no other fixing devices. The extraction column is on the top of the extraction instrument. It is easy to tilt and sometimes dumps, which makes the extraction column separate from the flow control valve, resulting in extraction failure

The invention discloses an independent fixing apparatus for extraction columns on the top of an extraction instrument. The apparatus is characterized by comprising a top plate, fixing support assemblies, and adjustment pressing-loosening assemblies, wherein the fixing support assemblies are installed outside four corner regions of the top plate, the adjustment pressing-loosening assemblies are installed on the top plate, each fixing support assembly comprises a fixed side plate, a movable side plate, and a locking-loosening handle, and each adjustment pressing-loosening assembly comprises a handle disc, a screw rod, a fixed disc, and a buffering cushion. The apparatus has the advantages of simple design and convenient adjustment, can ensure stable contact between the extraction columns andflow control valves, and prevents the extraction columns from tilting or tipping on the flow control valves to affect normal extraction.
Description
technical field [0001] The invention relates to the field of extraction column fixing devices, in particular to an independent fixing device for the extraction column at the top of an extraction instrument. Background technique [0002] Extractor is a commonly used sample pre-processing device in environmental monitoring, food safety, drug analysis and other analysis and testing. The traditional extractor uses vacuum negative pressure as the power source, so that the liquid loaded into the extraction column enters the recovery test tube inside the extractor through the extraction column and the flow control valve. The extractor is easy to operate and has a wide range of applications. At present, when the extraction instrument is actually used, the extraction column in the extraction instrument is placed directly on the flow control valve at the top of the extraction instrument. The contact area between the extraction column and the flow control valve is small, and there are...
