[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. This portable chemical reagent quantitative sampling meter is provided with a quantitative sampling meter component group. Volatile liquid is a commonly used liquid in chemical experiments. The current method of taking liquid is to open the bottle cap and measure it with a measuring cylinder and a pipette. In the process of taking liquid in this way, a large amount of volatile gas overflows from the reagent bottle. Because it is irritating, it causes great harm to the eyes, nose and throat of the person collecting the liquid. In the corresponding designed quantitative sampling meter component group, when it is necessary to quantitatively sample the chemical reagent, first insert the lower pipe fitting into the reagent liquid, pinch the rubber tube with your hand to block the rubber tube, and then turn the knob. By rotating the knob, the threaded rod will be driven to move up and down through the internal thread. By moving the threaded rod upward, the upward movement of the threaded rod will drive the piston member upward. When the piston member moves, negative pressure will be generated. The pressure will cause the lower pipe fitting to extract the chemical reagent, and the reagent liquid will enter the metering valve through the one-way liquid valve. The amount of reagent extracted is then determined by checking the reading component group. When the required amount of reagent is reached, stop rotating the knob, insert the end of the rubber tube away from the side pipe into the container where the reagent needs to be placed, and place it above the liquid in the container without contacting the liquid. Then, the knob can be reversed to move the threaded rod downward. The downward movement of the piston will discharge the reagent through the side pipe and the rubber tube into the container where the reagent needs to be placed. At this time, the overall quantitative sampling of the reagent is completed. The design of this quantitative sampling meter component group is simple in structure, easy to operate, and compact in overall structure. It is portable enough. When quantitatively sampling volatile reagents, the sealed structure can avoid the harm of volatile gases. At the same time, the knob is connected to the threaded rod by a thread. Compared with directly pulling the threaded rod and the piston, this position drive of the piston moves more slowly, which can achieve more accurate quantitative sampling.
[0013] 2. This portable chemical reagent quantitative sampler is provided with a reading component group. When sampling, it is necessary to ensure that the scale and the liquid level are in the same horizontal plane to accurately read the reading. However, some reagent bottles are inconvenient to pick up. At the same time, after picking up, the eyes and the position of the reagent scale lines need to be repeatedly adjusted to accurately read the reading, which reduces the efficiency of the sampler when in use. In the corresponding designed reading component group, the movement of the threaded rod will drive the movement of the top plate, and the movement of the top plate will drive the top ring, the side rod and the reading piece group. The reading piece group is composed of two arc plates. The two arc plates and the bottom of the piston are in the same plane. Reading is performed by reading the scale mark value between the two arc plates in the reading piece group, which can read more accurately and quickly, avoiding slow reading and inaccurate reading.

[0028] Working principle: Volatile liquids are commonly used in chemical experiments. The current method of taking liquids is to open the bottle cap and measure with a measuring cylinder and a pipette. In this way, a large amount of volatile gas overflows from the reagent bottle during the liquid taking process. Because of its irritation, it causes great harm to the eyes, nose and throat of the person collecting the liquid. In the corresponding designed quantitative sampling meter component group 01, when it is necessary to take quantitative samples of chemical reagents, first insert the lower pipe fitting 18 into the reagent liquid, pinch the rubber tube 110 with your hand to block the rubber tube 110, and then turn the knob 12. By rotating the knob 12, the threaded rod 14 will be driven to move up and down through the internal thread. By moving the threaded rod 14 upward, the upward movement of the threaded rod 14 will drive the piston 16 to move upward. When the piston 16 moves, negative pressure will be generated. The pressure will cause the lower pipe fitting 18 to extract the chemical reagent, and the reagent liquid will enter the measuring cylinder 11 through the one-way liquid valve 17, and then the reading component will be checked. Group 02 is used to determine the amount of extraction. When the required amount of reagent is reached, stop rotating the knob 12, and insert the end of the rubber tube 110 away from the side tube 19 into the container where the reagent needs to be placed, and it is above the liquid in the container and does not contact the liquid. Then, the knob 12 can be reversed to allow the threaded rod 14 to move downward. The downward movement of the piston 16 will discharge the reagent through the side tube 19 and the rubber tube 110 into the container where the reagent needs to be placed. At this time, the overall quantitative sampling of the reagent is completed. The design of this quantitative sampling meter component group 01 has a simple structure and is easy to operate. The overall structure is small and portable enough. When quantitatively sampling volatile reagents, the sealed structure can avoid the harm of volatile gases. At the same time, the knob 12 is connected to the threaded rod 14 through a thread. This position drive of the piston 16, compared with directly pulling the threaded rod 14 and the piston 16, the movement of the piston 16 is slower, and more accurate quantitative sampling can be achieved. When sampling, it is necessary to ensure that the scale and the liquid level are at the same horizontal plane to accurately read the reading. However, some reagent bottles are not convenient to pick up. At the same time, after picking up, it is necessary to repeatedly adjust the eyes and the position of the reagent scale line to accurately read the reading, which reduces the efficiency of the sampler when in use. In the corresponding designed reading component group 02, the movement of the threaded rod 14 will drive the movement of the top plate 15, and the movement of the top plate 15 will drive the top ring 21, the side rod 22 and the reading piece group 24. The reading piece group 24 is composed of two arc-shaped plates. The two arc-shaped plates and the bottom of the piston 16 are in the same plane. The reading is performed by reading the scale mark 111 value between the two arc-shaped plates in the reading piece group 24, which can read more accurately and quickly, avoiding slow reading and inaccurate reading.
