Description

Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a sampler for chemical reagents. Background Art

[0002] A chemical reagent sampler is a tool or device specifically used to obtain chemical reagent samples. Its main function is to represent the original chemical reagent through sampling for subsequent analysis and processing. Samplers are widely used in chemistry, biology, medicine, environmental protection and other fields.

[0003] The existing samplers for chemical reagents also have the following problems. The existing devices generally fix the sampler and then adjust the height of the sampler to sample the chemical reagent. Referring to the sampler for chemical reagents disclosed in the patent application with reference to announcement number CN215877993U, the utility model fixes the sampling tube in the inner cavity of the fixed ring through a fastening component. By operating the adjustment component, the sliding frame, the connecting arm, the fixed ring and the sampling tube are lowered, so that the sampling tube is extended into the chemical reagent pool. The depth is determined by the scale line on the sampling tube. When the depth reaches the appropriate depth, the lifting rod is pulled upward to draw the chemical reagent into the inner cavity of the sampling tube through the liquid extraction port. During extraction, the sampling tube is in a stable state, so that the depth of the extracted chemical reagent is stable, thereby making the chemical reagent detection result highly accurate.

[0004] However, the above-mentioned technical device rotates the bolt to drive the clamp to fix the sampler for sampling. After sampling, the bolt is rotated in the opposite direction to take down the sampler, which is inconvenient to use. After sampling, some chemical reagents will adhere to the outside of the sampler. After taking it off, the outside of the sampler needs to be wiped, which increases the operation steps, reduces the convenience of use, and is generally practical. Utility Model Content

The opposite sides of the mounting plate 231 are movably mounted with an arc plate 232, and the arc plate 232 is arc-shaped. A movable rod 233 is fixedly mounted on one side of the arc plate 232. A cleaning cotton 235 is fixedly mounted on the side of the arc plate 232 away from the movable rod 233. A spring 234 is sleeved on the outer side of the movable rod 233. One end of the rod 233 movably passes through the opposite side of the mounting plate 231 and extends to the outside of the mounting plate 231, and the moving trajectory of the arc plate 232 can be limited by the movable rod 233. One end of the spring 234 away from the arc plate 232 is fixedly installed on the opposite side of the mounting plate 231, and the other end of the spring 234 is fixedly installed on one side of the arc plate 232. One side of the cleaning cotton 235 is tightly attached to the outside of the sampler body 221, and the elastic force of the spring 234 can be used to resist the arc plate 232 so that the cleaning cotton 235 is tightly attached to the outside of the sampler body 221.
