[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 3, in the embodiment of the present utility model, a sampling device for facilitating the production of electrolyte includes a sampling container 1 with open tops and bottoms. A quantitative mechanism is slidably installed outside the sampling container 1, and the quantitative mechanism is used to hold a fixed volume of electrolyte. A counterweight 6 is slidably connected up and down at the bottom opening of the sampling container 1. The counterweight 6 at the highest point is used to close the bottom opening of the sampling container 1, and the outer diameter of the upper half of the counterweight 6 matches the inner diameter of the bottom opening of the sampling container 1, and the lower half of the counterweight 6 is in a conical structure; a connecting rod 5 is fixedly connected to the top of the upper half of the counterweight 6, and a handle 11 is fixedly connected to the top of the connecting rod 5.

[0019] In this embodiment: First, according to the volume of the sample to be taken, the quantitative mechanism is adjusted. After the adjustment is completed, the device is lowered by holding the handle 11. When the liquid level of the electrolyte is flush with the bottom end face of the sliding part of the adjustment mechanism, at this time, the sampling container 1 cannot move downward. At this time, hold the handle 11 and push the connecting rod 5 downward. The downward-moving handle 11 pushes the counterweight 6 downward. At this time, the counterweight 6 moves downward, while the sampling container 1 remains stationary. Only the upper half of the counterweight 6 is effectively misaligned with the bottom opening of the sampling container 1. At this time, the liquid flows through the bottom opening of the sampling container 1 and into the sampling container 1, and the air in the sampling container 1 is squeezed out until the liquid level height in the sampling container 1 is flush with the external liquid level of the sampling container 1, and the purpose of quantitative liquid sampling can be completed;

[0020] After sampling is completed, at this time, pull the handle 11 upward. The upward-moving handle 11 drives the counterweight 6 upward through the connecting rod 5. At this time, the sampling container 1 remains stationary. Until the counterweight 6 contacts the bottom end of the sampling container 1, the counterweight 6 can pull the entire sampling container 1 upward. At this time, the sealing member on the top plane of the lower half of the counterweight 6 deforms under the action of the extrusion force, and the electrolyte in the sampling container 1 can be sealed to prevent the electrolyte from flowing out of the bottom opening of the sampling container 1.

[0021] Please refer specifically to Figure 1 and Figure 2 , four inclined rods 7 are fixedly connected to the top of the sampling container 1, a fixed ring 8 is fixedly connected to the top ends of the four inclined rods 7, a fixing plate 9 is fixedly connected to the outer circumference of the connecting rod 5, a sliding rod 10 is integrally formed at the bottom end of the fixing plate 9, and a circular hole for the sliding rod 10 to slide up and down is opened inside the fixed ring 8. An anti-detachment block 15 is integrally formed at the bottom end of the sliding rod 10.

[0022] In this embodiment: When the handle 11 moves downward, the handle 11 drives the connecting rod 5 downward. The downward-moving connecting rod 5 drives the fixing plate 9 to move downward synchronously. The fixing plate 9 drives the sliding rod 10 to move downward along the circular hole inside the fixed ring 8;

[0023] When the handle 11 drives the connecting rod 5 to move upward, the upward moving connecting rod 5 drives the fixing plate 9 to move upward synchronously. The fixing plate 9 then drives the sliding rod 10 to move upward along the circular hole inside the fixing ring 8 until the top surface of the anti-detachment block 15 contacts the bottom end of the fixing ring 8. This design method can prevent the sampling container 1 from rotating during the sampling process and avoid excessive shaking of the liquid level caused by the rotation of the sampling container 1.

[0024] Please refer specifically to Figure 1 and Figure 2 , the quantitative mechanism includes two guide rails 2 symmetrically and fixedly connected to the outer periphery of the sampling container 1. An upper slider 14 is slidably connected up and down inside the guide rail 2. A sliding plate 3 that is slidably connected up and down to the outer periphery of the sampling container 1 is fixedly connected to the outside of the upper slider 14. A rubber pad is fixedly connected by adhesive glue at the contact position between the upper slider 14 and the inner wall of the guide rail 2. The quantitative mechanism also includes a lower slider 13 that is slidably connected up and down to the inner wall of the guide rail 2. The lower slider 13 is located below the upper slider 14, and the outer wall of the lower slider 13 is slightly smaller than the inner wall of the guide rail 2. A floating plate 4 that is slidably connected up and down to the outer periphery of the sampling container 1 is fixedly connected to the outer periphery of the lower slider 13. Scale lines are formed vertically on the outer periphery of the sampling container 1.

[0025] In this embodiment: First, by pulling the sliding plate 3 up and down, the sliding plate 3 drives the upper slider 14 to be stressed. This force overcomes the friction of the rubber pad, realizing the up and down movement of the upper slider 14 inside the guide rail 2 until the bottom end surface of the sliding plate 3 is flush with the scale of the sampling volume. Then, when the sampling container 1 is lowered into the electrolyte, when the floating plate 4 contacts the electrolyte liquid level, the bottom of the floating plate 4 is always located on the electrolyte liquid surface. As the sampling container 1 is lowered, the receiving groove 12 at the bottom of the sliding plate 3 accommodates the floating plate 4. At this time, under the restriction of the floating plate 4, the sampling container 1 cannot move downward, which realizes quantitative liquid sampling.

[0026] Please refer specifically to Figure 2 , a receiving groove 12 is opened at the bottom end of the sliding plate 3, and the inner wall of the receiving groove 12 is fitted with the outer wall of the floating plate 4.

[0027] In this embodiment: After the receiving groove 12 completely coincides with the floating plate 4, the bottom end surface of the floating plate 4 is flush with the bottom end surface of the sliding plate 3, which is also flush with the scale line, and quantitative sampling according to the scale can be realized.

[0028] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
