Technical Field

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

[0002] Chemistry is a type of natural science that studies the composition, properties, structure and laws of change of substances at the molecular and atomic levels, and creates new substances. Chemistry is one of the main methods and means used by humans to understand and transform the material world, and is an important symbol of social civilization.

[0003] In the process of conducting chemical experiments, sampling of liquid samples for chemical experiments is one of the indispensable processes. Samplers are required for liquid sampling, and most common liquid samplers are droppers. The applicant believes that dropper sampling has the following problems:

[0004] 1. When doing chemical experiments, there are often more than one type of liquid that needs to be sampled, but the dropper can only absorb one type of liquid when sampling. The next sampling can only be continued after the absorbed liquid is put into the beaker. Generally, during the experiment, there are many experimental items, and repeated absorption actions will waste a lot of time;

[0005] 2. During the experiment, it is necessary to mix several liquids to see the effect, but the dropper does not have the mixing conditions, so the inhaled chemical liquid needs to be placed in another beaker for mixing and observation, which will also cause the problem mentioned in the first question. Utility Model Content

[0006] The utility model aims to provide a chemical experiment sampler to solve the problem that more than one type of liquid needs to be sampled during chemical experiments, and a dropper can only absorb one type of liquid during sampling, and the next sampling can only be continued after the absorbed liquid is placed in a beaker. Generally, there are many experimental items during experiments, and repeated absorption actions will waste a lot of time. During experiments, it is necessary to mix several liquids to see the effect, but the dropper does not have the mixing conditions, so it is necessary to put the absorbed chemical liquid in another beaker for mixing and observation, which will also cause the problem in the first question mentioned above.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chemical experiment sampler, comprising:

[0008] A volume container, wherein a suction port is arranged at the bottom of the volume container, and a top plate is fixedly arranged at the top of the volume container;

[0009] A push rod is arranged at the top of the volume container, a hollow movable rod is arranged at the bottom of the push rod, and a solid movable rod is arranged at one end of the hollow movable rod.

[0010] Preferably, a thread groove is formed at the bottom of the volume container, the top of the suction port is embedded in the thread groove and threadedly connected thereto, and the inner wall of the volume container is flush with the inner wall of the top of the suction port.

[0011] Preferably, the volume container is hollow, the bottom of the push rod passes through the top plate and is embedded in the volume container to be movably connected thereto, and the outer side of the bottom of the push rod is tightly fitted with the inner wall of the volume container.

[0012] Preferably, a limit piece is fixedly provided on the top of the top plate, a slide groove is provided on the outer side of one end of the limit piece, and one end of a hollow movable rod is embedded in the slide groove and movably connected with the slide groove.

[0013] Preferably, the two hollow movable rods are crossed in an "X" shape, and a first connecting shaft is arranged on the outside of one end of the hollow movable rod, and one solid movable rod is embedded in the inside of one hollow movable rod and is rotatably connected to it through the first connecting shaft.

[0014] Preferably, the two solid movable rods cross to form an "X" shape, and a sliding rod is fixedly arranged between the two hollow movable rods located at one end of the sliding groove.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. This device pushes the slide rod, which drives the hollow movable rod and the solid movable rod to push the push rod upward, so the liquid will be sucked into the volumetric container. If you stop pushing the slide rod, the device will stop sucking the chemical liquid, and if you continue to push the slide rod, the device will continue to suck the chemical liquid;

[0018] 2. There are scales on the outside of the volumetric device, so you can see how many milliliters have been absorbed when sampling chemical liquids. The space of the volumetric device is large enough, so some chemical liquids that need simple mixing and observation can be directly placed in the volumetric device and shaken for mixing and observation.

[0027] See also Figure 1-4 The utility model provides a technical solution: a chemical experiment sampler, comprising a volume container 10, the interior of which is slidably connected with a push rod 13, the bottom of the volume container 10 is threadedly fixed with a suction port 11, and the top of the volume container 10 is integrally fixedly connected with a top plate 12;

[0028] The stopper 20 is integrally fixedly connected to the top plate 12, the outer side of one end of the hollow movable rod 23 is slidably connected to the stopper 20 through the slide groove 21, and a slide rod 22 is welded and fixed between the two hollow movable rods 23 on the outer side of the stopper 20;

[0029] The solid movable rod 24 is embedded in the hollow movable rod 23 and is rotatably connected to it through the first connecting shaft. A connecting head 25 is welded and fixed to the bottom of the top of the push rod 13. The top of one hollow movable rod 23 is rotatably connected to the connecting head 25 through the second connecting shaft, and the "X" where the two hollow movable rods 23 cross is rotatably connected through the third rotating shaft.

[0030] Working principle: insert the suction port 11 into the thread groove at the bottom of the volume container 10, rotate the suction port 11 clockwise so that the top of the suction port 11 is fixed with the bottom thread of the volume container 10, and put the suction port 11 at the bottom of the volume container 10 into the chemical experiment product to be sucked;

[0031] The slide bar 22 is pushed toward one end of the limit member 20, so that the slide bar 22 slides toward one end of the slide groove 21 inside the slide groove 21. When the slide bar 22 slides toward one end of the slide groove 21, it drives one end of the hollow movable rod 23 to extend toward the top of the limit member 20, and when the hollow movable rod 23 extends, it drives one end of the solid movable rod 24 to extend toward the top of the other end of the limit member 20. The slide bar 22 is pushed continuously, so that the hollow movable rod 23 and the solid movable rod 24 continue to extend upward. Therefore, one of the hollow movable rod 23 and the solid movable rod 24 will push the push rod 13 upward, so that the push rod 13 slides upward inside the volumetric container 10, so that the chemical experiment product in the beaker will be drawn into the volumetric container 10.

[0032] When the push rod 13 is pushed downward, the hollow movable rod 23 and the solid movable rod 24 will move downward on the top of the volume container 10 , so that the chemical experiment product inside the volume container 10 will also be discharged from the suction port 11 .
