[0002] Chemical reagents and auxiliaries are the various excipients and additives used in chemical experiments.

[0003] To ensure the quality of chemical reagents and auxiliaries, sampling and testing are required each time they are produced. Sampling requires the use of a sampling device, but most existing sampling devices are syringe-type. This means that after sampling, the syringe needs to be reinserted into the container for injection. The sample cannot be directly transferred to the container after sampling. As a result, when moving the sampling device, the sample inside may leak because the needle angle is downward beforehand.

[0004] Therefore, how to provide a chemical reagent and auxiliary agent sampling device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of a chemical reagent and auxiliary agent sampling device according to an embodiment of the present invention, comprising: Graduated cylinder 1; Extraction tube 3 is movably installed on the top of measuring cylinder 1; Piston rod 2 is movably inserted into the inside of measuring cylinder 1; Connecting plate 16 is fixedly installed on the bottom surface of measuring cylinder 1; The guide tube 5 is fixedly installed on the side of the measuring cylinder 1, and its bottom is movably inserted into the middle of the right end of the connecting plate 16. A partition structure is installed on the side of the lower end of the measuring cylinder 1 to block the upper end of the guide tube 5. Sample bottle 4 is located below the connecting plate 16 and is movably connected to the bottom of the guide tube 5.

[0021] In this embodiment of the utility model, when in use, the sample bottle 4 is inserted into the lower end of the guide tube 5 and fixed against the connecting plate 16. Then, the extraction tube 3 is inserted into the container to be sampled. Then, according to the scale value on the surface of the measuring cylinder 1, the extension length of the piston rod 2 is adjusted so that the sample can be quantitatively extracted. By setting a partition structure between the measuring cylinder 1 and the guide tube 5, and contacting the descending piston rod 2 inside the measuring cylinder 1, the sample bottle 4 is kept in a blocked state when not being introduced, thus preventing foreign matter from entering and causing the sample bottle 4 to become contaminated.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the bottom of the measuring cylinder 1 is movably provided with a clamping structure, which includes a slide rod 10 and a clamping plate 12. The slide rod 10 is symmetrically installed at the bottom of the right end of the connecting plate 16, and a slider 11 is symmetrically slidably installed on its surface. The clamping plate 12 is fixedly installed at the bottom of the slider 11 to clamp the surface of the sample bottle 4. A second spring 13 is movably sleeved on the surface of the slide rod 10 and movably abuts against the surface of the slider 11. The surfaces of the two clamping plates 12 are provided with reinforcing units.

[0023] In this embodiment of the utility model, when in use, the sample bottle 4 is placed between the two clamping plates 12 and inserted into the lower end of the guide tube 5. Then, under the elasticity of the second spring 13 on the surface of the slide bar 10, the slider 11 slides at the bottom of the connecting plate 16 and contacts the surface of the sample bottle 4, thereby simply clamping and fixing it. By setting up a clamping structure and a reinforcement unit, the sample bottle 4 can be clamped in multiple ways, thereby preventing the sample bottle 4 from falling when moving and collecting samples.

[0024] like Figure 2 and Figure 5 As shown, in a preferred embodiment of the present invention, the partition structure includes a movable sealing plate 6, a lifting groove 7, a top plate 8, and a first spring 9. The lifting groove 7 is opened on the inner side of the bottom end of the measuring cylinder 1. The movable sealing plate 6 is movably inserted into the upper part of the lifting groove 7 to block the guide pipe 5. The top plate 8 is fixedly installed on the inner side of the bottom of the movable sealing plate 6. The first spring 9 is fixedly installed on the bottom of the top plate 8 and is fixedly connected to the bottom of the lifting groove 7.

[0025] In this embodiment of the utility model, when in use, the extraction tube 3 is placed upward, and then the piston rod 2 is pulled outward, so that the piston rod 2 contacts the top plate 8 on the inner side of the bottom of the movable sealing plate 6, so that the top plate 8 overcomes the first spring 9 in the lifting groove 7, thereby connecting the guide tube 5 with the measuring cylinder 1, so that the sample in the measuring cylinder 1 can quickly enter the sample bottle 4 through the guide tube 5. By setting up a partition structure, the top plate 8 will not be pressurized when the piston rod 2 does not descend, thereby controlling the on / off time of the guide tube 5, which facilitates the entry time of the anti-Japanese war sample.

[0026] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the reinforcement unit includes a positioning band 15, and a through hole 14 is provided at the right end of the left side clamping plate 12. The positioning band 15 is fixedly installed at the left end of the right side clamping plate 12 and passes through the surface of the through hole 14, and is adhered to the surface of the right side clamping plate 12.

[0027] In this embodiment of the utility model, when in use, by setting a positioning strap 15 on the clamp 12, the position of the clamp 12 can be reinforced for a second time, thereby improving the stability of the sample bottle 4.

[0028] like Figure 2 and Figure 3 As shown, in a preferred embodiment of this utility model, the surface of the right through hole 14 is provided with a circular surface, and the inner side of the positioning band 15 is provided with a barbed surface.

[0029] In this embodiment of the utility model, when in use, a circular surface is provided on the surface of the right through hole 14, and a barbed surface is provided on the inner side of the positioning strip 15, thereby facilitating the adhesion between the two.

[0030] like Figure 3 As shown, in a preferred embodiment of the present invention, the length of the through hole 14 is less than the length of the clamping plate 12, and the edge of the through hole 14 is arc-shaped.

[0031] In this embodiment of the utility model, when in use, by making the length of the through hole 14 less than the length of the clamping plate 12, and by setting the edge of the through hole 14 in an arc shape, it is easier for the positioning belt 15 to enter and exit, and damage to the surface of the positioning belt 15 is reduced.

[0032] like Figure 2 and Figure 5 As shown, in a preferred embodiment of the present invention, the diameter of the movable sealing plate 6 is greater than the inner diameter of the guide tube 5, and the inner side of the top plate 8 extends into the interior of the measuring cylinder 1.

[0033] In this embodiment of the utility model, when in use, by making the diameter of the movable sealing plate 6 larger than the inner diameter of the guide tube 5, it is convenient to seal the guide tube 5 and reduce the entry of foreign objects. The top plate 8 extends to the inside of the measuring cylinder 1 through the inner side, and when the piston rod 2 descends, it will squeeze the top of the top plate 8.

[0034] The present invention provides a chemical reagent and auxiliary agent sampling device in the above embodiments. When in use, the sample bottle 4 is placed between two clamping plates 12 and inserted into the lower end of the guide tube 5. Then, under the elasticity of the second spring 13 on the surface of the slide bar 10, the slider 11 slides at the bottom of the connecting plate 16 and contacts the surface of the sample bottle 4, thereby simply clamping and fixing it. Then, pull the outer end of the positioning band 15 to adjust its length extending out of the through hole 14, thereby bringing the distance between the two clamps 12 closer and improving the stability of the two clamps 12, thus fixing the position of the sample bottle 4. Then, the extraction tube 3 is inserted into the container to be sampled. Then, according to the scale value on the surface of the measuring cylinder 1, the extension length of the piston rod 2 is adjusted so that the sample can be quantitatively extracted. Then, the extraction tube 3 is placed upwards, and the piston rod 2 is pulled outwards. This causes the piston rod 2 to contact the top plate 8 on the inner side of the bottom of the movable sealing plate 6, so that the top plate 8 overcomes the first spring 9 in the lifting groove 7, thereby connecting the guide tube 5 with the measuring cylinder 1, so that the sample in the measuring cylinder 1 can quickly enter the sample bottle 4 through the guide tube 5.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
