DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a chemical reagent laboratory solution delivery device, including a funnel 4, a connecting tube 12 fixedly connected to the bottom of the funnel 4, the neck of the funnel 4 is reasonably designed, which can control the flow rate of the solution and avoid splashing or overflowing of the solution during the pouring process. The outer wall of the connecting tube 12 is slidably connected to a holding tube 1, which is made of chemically resistant glass material with good transparency and chemical stability. It can accommodate various chemical solutions without reaction or damage. A plurality of card slots 5 are opened inside the holding tube 1, and both sides of the connecting tube 12 are fixedly connected It is connected to a fixed block 3, which is made of sturdy engineering plastics, has good insulation performance and chemical corrosion resistance, and can remain stable in various chemical experimental environments. The outer wall of the fixed block 3 is fixedly connected with a pull ring 6, which is made of stainless steel. The surface is finely polished, smooth and not easy to rust. It also has good corrosion resistance, ensuring that it will not be worn or corroded due to contact with the hand during long-term use. One side of the pull ring 6 is fixedly connected with a moving column 7, which is made of high-strength aluminum alloy material, with light weight and high strength. , it can remain stable in the process of transmitting tension without bending or deformation. One side of the moving column 7 is fixedly connected with a card column 10. The card column 10 is made of high-quality steel. The surface is quenched, with high hardness and good wear resistance. It can maintain good shape and dimensional accuracy during long-term plugging and unplugging. The card column 10 is set on the inner wall of the card slot 5, and the outer wall of the moving column 7 is provided with a spring 9. One side of the spring 9 is fixedly connected with a fixing ring 8. The fixing ring 8 is fixedly connected to the inside of the fixed block 3. The bottom of the fixed block 3 is fixedly connected with an indicator strip 11. The indicator strip 11 is made of fresh It is made of bright colored plastic, which is convenient for users to accurately read the height of the solution. The outer wall of the indicator bar 11 is provided with a fixed plate 2, which is fixedly connected to the outer wall of the holding tube 1. The fixed plate 2 is made of stainless steel plate, and the surface is polished and smooth. The outer wall of the fixed plate 2 is fixedly connected with multiple data strips 20. The data strips 20 are printed on the outer wall of the fixed plate 2 using high-precision printing technology. The scale is clear and not easy to wear, which can provide an accurate reference for the adjustment of the indicator bar 11. An adjustment component is provided at the bottom of the holding tube 1, and the adjustment component is used to adjust the flow rate of the solution.

[0034] Specifically, during the use of the device, when the pull rings 6 on both sides are first pulled, the pull ring 6 will drive the card column 10 to move out of the card slot 5 through the moving column 7 during the movement. The card column 10 will drive the spring 9 to compress during the movement. During the compression process, the spring 9 can store energy to provide power for the subsequent reset operation. Then the indicator bar 11 at the bottom of the fixed block 3 moves up and down. The indicator bar 11 can be adjusted according to the value on the data bar 20 on the outer wall of the fixed plate 2. After the indicator bar 11 is moved to a suitable height, the pulling force of the pull ring 6 is released. At this time, the rebound force of the spring 9 is used to push the card column 10 to move to the inside of the card slot 5, thereby fixing the card column 10 in the position, thereby ensuring the stability of the fixed block 3. Then, the solution is poured into the interior of the holding tube 1 through the funnel 4. When the top of the solution reaches the bottom of the connecting tube 12, the precise control of the amount of solution poured is achieved, thereby ensuring the accuracy of the chemical experiment.

[0035] Reference Figure 4 - Figure 5 , the adjustment component includes an arc-shaped card plate 18, which is arranged at the bottom of the holding tube 1, and the outer wall of the holding tube 1 is fixedly connected to a fixed tube 13, and a slide groove 21 is opened inside the fixed tube 13. The fixed plate 2 14 is rotatably connected to the inside of the fixed tube 13. The fixed plate 2 14 is made of a solid aluminum alloy plate and has high strength and stability. It can withstand various forces generated during operation. The outer wall of the fixed plate 2 14 is fixedly connected to a control plate 19. The control plate 19 is made of high-strength plastic material and the surface is anti-slip treated to facilitate easy pulling by the user. The control plate 19 is slidably connected to the inside of the slide groove 21. A plurality of slide grooves 15 are opened on the top of the fixed plate 2 14, and a plurality of leakage holes 22 are opened at the bottom of the fixed plate 2 14. The fixed plate 2 14 is provided with a plurality of slide grooves 15. It is placed at the bottom of multiple arc-shaped card plates 18. The arc-shaped card plates 18 are made of corrosion-resistant stainless steel material with good toughness and strength, and can maintain their shape unchanged during long-term use. The inside of one side of the arc-shaped card plate 18 is fixedly connected with a slide bar 16. The slide bar 16 is made of wear-resistant nylon material and has a low friction coefficient. The slide bar 16 is slidably connected to the inner wall of the slide groove 15. The inside of the other side of the arc-shaped card plate 18 is fixedly connected with a rotating shaft 17. The rotating shaft 17 is made of high-quality steel, has been precisely processed, has a smooth surface, and has low rotational resistance, which can ensure the smooth rotation of the arc-shaped card plate 18. The rotating shaft 17 is rotatably connected to the inside of the fixed plate 2 14. The arc-shaped card plate 18 is set at the top of the leakage hole 22, and the leakage holes 22 are evenly distributed in a specific area and arranged in a circular array.

[0036] Specifically, when the device is pouring reagents, when the control plate 19 is first pulled, a force is generated and transmitted to the fixed plate 2 14. As the control plate 19 is pulled, the fixed plate 2 14 begins to rotate. During the rotation of the fixed plate 2 14, the arc-shaped card plate 18 is driven to rotate with the rotating shaft 17 as the center of the circle, and the slide bar 16 on the other side of the arc-shaped card plate 18 will also slide smoothly on the inner wall of the slide groove 15. By adjusting the rotation angle of the arc-shaped card plate 18, the exposed area of ​​the leakage hole 22 can be accurately controlled. When the solution flow rate needs to be adjusted, the exposed area of ​​the leakage hole 22 is changed by changing the rotation angle of the arc-shaped card plate 18, so as to achieve targeted adjustment of the flow rate of the solution from the inner wall of the leakage hole 22 to the inside of the reagent. This can avoid the situation where the solution flow rate is too fast or too slow, thereby affecting the chemical catalytic reaction. Moreover, since the leakage holes 22 are distributed in a ring array, the solution can flow evenly into the inside of the reagent. This uniform inflow method avoids the accumulation of solutions that affect the mixing of solutions inside the reagents. The uniform distribution of solutions helps to fully mix the components inside the reagents, improves the efficiency and uniformity of chemical reactions, and enhances the applicability of the equipment, enabling it to meet the needs of different chemical experiments and reactions.

[0037] Working principle: When using the device, first pull the pull rings 6 on both sides. During the movement, the pull rings 6 will drive the card column 10 to move out of the card slot 5 through the moving column 7. The card column 10 will drive the spring 9 to compress during the movement, and then move the indicator bar 11 at the bottom of the fixed block 3 up and down. According to the data strip 20 on the outer wall of the fixed plate 2, the indicator bar 11 is moved to a suitable height. Then, release the pulling force of the pull ring 6, and use the rebound force of the spring 9 to push the card column 10 to move to the inside of the card slot 5. Use the card slot 5 to fix the card column 10 to ensure the stability of the fixed block 3. Then, pour the solution into the inside of the holding tube 1 through the funnel 4. When the top of the solution reaches the bottom of the connecting tube 12, the precise control of the amount of solution poured is achieved to ensure chemical reality. In order to improve the accuracy of the test, when the reagent is poured into the equipment, the control plate 19 is pulled to rotate the fixed plate 2 14. During the rotation of the fixed plate 2 14, the arc-shaped card plate 18 will be driven to rotate with the rotating shaft 17 as the center of the circle, and the slide bar 16 on the other side of the arc-shaped card plate 18 will slide on the inner wall of the slide groove 15. The exposure area of ​​the leakage hole 22 is controlled by adjusting the rotation angle of the arc-shaped card plate 18, so that the flow rate of the solution from the inner wall of the leakage hole 22 to the inside of the reagent is adjusted according to the actual situation, so as to avoid the situation where the solution flow rate is too fast or too slow, thereby affecting the chemical catalytic reaction. In addition, the leakage holes 22 in the annular array are used to make the solution flow evenly into the reagent, so as to avoid the accumulation of solution and thus affecting the mixing of the solution inside the reagent, thereby enhancing the applicability of the equipment.
