[0002] In the field of modern chemical reagent testing, pipettes are the core tools for accurately measuring and transferring liquids. Their frequency of use and operational precision directly affect the accuracy and reliability of experimental results. As chemical analysis technology develops towards micro and trace detection, the reliance on pipettes is increasing. In the experimental process, it is often necessary to use multiple pipettes of different specifications at the same time to meet diverse detection needs.

[0003] Different researchers have different heights, and therefore different suitable operating heights. Without height adjustment mechanisms, taller people may need to bend over to operate, while shorter people may need to stand on tiptoe or use auxiliary tools to elevate themselves. Both of these factors make operation uncomfortable and can lead to physical fatigue over time, affecting work efficiency and experimental accuracy. Utility Model Content

A knob drives a first bevel gear, which in turn drives a second bevel gear, which in turn drives a screw. The screw drives a sliding plate, which in turn drives a connecting plate, which in turn drives a mounting platform. This allows each user to adjust the pipette to their ideal height, making operation more comfortable and natural, reducing fatigue caused by bending over or tiptoeing, and improving work efficiency and experimental accuracy.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a pipette suspension bracket structure for chemical reagent testing, comprising: a base plate 1 serving as the main support; a fixed box 2 connected to the base plate 1 via a rotating assembly; a knob 3 rotatably connected to the inner wall of the fixed box 2; a screw 6 connected to the knob 3 via a transmission assembly; a sliding plate 7 threadedly connected to the outer wall of the screw 6; connecting plates 8 fixedly connected to both sides of the top of the sliding plate 7; and a mounting platform 9 fixedly connected to the top of the connecting plate 8. The transmission assembly includes a first bevel gear 4 located at the rear end of the knob 3 and a second bevel gear 5 located on the outer wall of the screw 6, with the first bevel gear 4 and the second bevel gear 5 meshing together. The outer wall of the screw 6 is rotatably connected to the inner wall of the fixed box 2, and the outer wall of the sliding plate 7 is slidably connected to the inner wall of the fixed box 2. The inner wall of the mounting platform 9 is provided with multiple placement slots 10, and the inner wall of the knob 3 is provided with bolts 11.

[0024] Specifically, when adjusting the height of the pipette suspension bracket, the following steps can be taken: Rotate knob 3, which is coaxially connected to the first bevel gear 4. Rotating knob 3 will cause the first bevel gear 4 to rotate synchronously. The first bevel gear 4 meshes with the second bevel gear 5, and the rotation of the first bevel gear 4 transmits power to the second bevel gear 5, causing it to rotate as well. The second bevel gear 5 is fixedly connected to the screw 6, and the rotation of the second bevel gear 5 in turn drives the screw 6 to rotate. The screw 6 and the sliding plate 7 are connected by a thread. When the screw 6 rotates, the sliding plate 7 will move along the axial direction of the screw 6. The sliding plate 7 is connected to the connecting plate 8. The movement will cause the connecting plate 8 to move synchronously, and the connecting plate 8 is fixedly connected to the mounting platform 9, ultimately realizing the up and down movement of the mounting platform 9. In this way, experimenters of different heights can adjust the pipette on the mounting platform 9 to the ideal height according to their own needs, avoiding physical fatigue caused by bending over or tiptoeing, making the operation more comfortable and natural, and helping to improve work efficiency and experimental accuracy. After adjusting to the appropriate height, turn the bolt 11 to make its end fit tightly against the fixing box 2, thereby restricting the rotation of the knob 3 and fixing the adjusted height. The placement slot 10 set on the mounting platform 9 can be used to safely and stably place the pipette.

[0025] Reference Figure 3 and Figure 4 The rotating assembly includes a connecting platform 12 fixedly connected to the top of the base plate 1. A rotating rod 13 is rotatably connected to the inner wall of the connecting platform 12. A gripping plate 14 is fixedly connected to the right end of the rotating rod 13. A fixing cylinder 15 is fixedly connected to the inner wall of the gripping plate 14. A limiting plate 16 is slidably connected to the inner wall of the fixing cylinder 15. A pull rod 17 is fixedly connected to the inner wall of the limiting plate 16. A spring 18 is provided between the inner walls of the fixing cylinder 15 and the limiting plate 16. The outer wall of the fixing box 2 is fixedly connected to the outer wall of the rotating rod 13. A plurality of fixing holes 19 are provided on the inner wall of the connecting platform 12 corresponding to the pull rod 17. One end of the spring 18 is connected to the limiting plate 16, and the other end of the spring 18 is connected to the inner wall of the fixing cylinder 15.

[0026] Specifically, when the angle of the support needs to be adjusted, first pull the lever 17 to disengage it from the fixing hole 19. Then, hold the grip plate 14 and rotate the rotating rod 13 using the grip plate 14 as the fulcrum. Since the rotating rod 13 is connected to the fixing box 2, the fixing box 2 will also rotate as the rotating rod 13 rotates, thereby driving the pipette fixed on it to adjust its angle. In this way, the angle of the pipette can be flexibly changed to suit the operating habits and observation lines of different experimental personnel, effectively relieving hand fatigue. When the angle is adjusted to the ideal position, release the lever 17. Under the elastic action of the spring 18, the limiting plate 16 will rebound under force, driving the lever 17 to re-insert into the fixing hole 19, thereby firmly fixing the adjusted angle and ensuring that the support angle remains stable and does not shift during subsequent use.

[0027] Working principle: First, when the angle needs to be adjusted, pull the lever 17 to disengage it from the fixing hole 19. Then, grasp the grip plate 14 and simultaneously rotate the rotating rod 13. As the rotating rod 13 rotates, it drives the fixing box 2 to rotate, allowing for angle adjustment to suit different operating habits and viewing angles, reducing hand fatigue. Once the desired position is reached, release the lever 17. When the lever 17 is released, the spring 18 will spring the limiting plate 16, causing it to move. As the limiting plate 16 springs, the lever 17 moves and inserts into the fixing hole 19 for fixation. To adjust the height, rotate the knob 3. The first bevel gear 4 rotates, which in turn drives the second bevel gear 5 to rotate. The second bevel gear 5 rotates, which in turn drives the screw 6 to rotate. The screw 6 rotates, which in turn drives the slide plate 7 to move. The slide plate 7 moves, which in turn drives the connecting plate 8 to move. The connecting plate 8 moves, which in turn drives the mounting platform 9 to move. This allows each person to adjust the pipette to the ideal height according to their own height, making the operation more comfortable and natural, reducing physical fatigue caused by bending over or standing on tiptoe, and improving work efficiency and experimental accuracy. When the appropriate height is reached, the bolt 11 is turned to make the fixed box 2 fit against the knob 3 for fixation. The placement slot 10 can be used to place the pipette.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
