[0002] Chemical reagents are various high-purity chemical substances used in chemical research, component analysis, and chemical experiments. They are widely used in the synthesis, separation, qualitative and quantitative analysis of substances and can be considered the eyes of chemists. Chemical reagents are indispensable in the daily work of factories, schools, hospitals and research institutes. When using chemical reagents, different auxiliaries need to be mixed in proportion, and using a dropper to mix chemical reagent auxiliaries is a common and accurate operation method.

[0003] A search revealed Chinese patent publication number CN218981413U, which discloses a chemical reagent and auxiliary agent mixing device. The device includes a support base, a mounting frame fixedly installed on the upper wall of the support base, and a vertically penetrating equipment slot at the center of the left and right side walls of the mounting frame. A rotating device and a dropper clamping device are installed within the equipment slot. The rotating device includes a rotating shaft vertically installed within the equipment slot, with its bottom end movably mounted on the bottom wall of the equipment slot via a bearing. This patent has the following shortcomings: while it allows for vertical addition of auxiliaries using a dropper, it cannot accommodate droppers of different diameters, only fixing droppers of a single size, thus limiting the device's applicability. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that it is impossible to vertically fix droppers of different sizes, and to propose a chemical reagent and auxiliary agent mixing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chemical reagent and auxiliary agent mixing device includes a stable base and a rectangular frame and a beaker disposed above the stable base. Multiple cylinders for fixing droppers are slidably connected to the rectangular frame. The device also includes multiple sliding rods slidably connected to the cylinders. Each sliding rod is fixedly connected to an arc-shaped clamp and a drive rod. The cylinders are provided with a drive component and a limiting component corresponding to the drive rod. A first spring is sleeved on each sliding rod, with both ends of the first spring abutting against the drive rod and the outer wall of the cylinder, respectively.

[0007] Preferably, a vertical plate is fixedly connected to the top of the stabilizing base, a cavity is formed inside the vertical plate, and a screw is rotatably connected inside the cavity of the vertical plate.

[0008] Preferably, a slider is threaded onto the screw, one end of the rectangular frame is fixedly connected to the slider, and a vertical groove is provided on one side of the vertical plate.

[0009] Preferably, a handwheel is fixedly connected to the top of the screw, the handwheel is rotatably connected to the vertical plate, and an extension block is fixedly connected to both sides of each cylinder.

[0010] Preferably, each end of the rectangular frame is fixedly connected to two mounting ears, and a guide rod is fixedly connected between each of the two mounting ears, with the extension block slidably connected to the guide rod.

[0011] Preferably, the driving component includes an annular groove plate fixedly connected to the outer wall of the cylinder, and a driving disk is rotatably connected inside the annular groove plate. The driving disk has an arc-shaped sliding hole adapted to the driving rod.

[0012] Preferably, the limiting member includes a ratchet fixedly connected to the outer wall of the cylinder, a round rod fixedly connected to the top of the drive disc, a pawl rotatably connected to the round rod, and the pawl slidably connected to the round rod.

[0013] Preferably, a pull plate is fixedly connected to the top of the pawl, a second spring is sleeved on the round rod, a support plate is fixedly connected to the top of the round rod, the two ends of the second spring are fixedly connected to the support plate and the pull plate respectively, and a baffle is fixedly connected to the drive disc.

[0014] Compared with the prior art, the present invention provides a chemical reagent and auxiliary agent proportioning device, which has the following beneficial effects:

[0015] 1. This chemical reagent and auxiliary agent mixing device, through a driving component, controls the sliding of a driving rod, which in turn moves a sliding rod on a cylinder, causing multiple arc-shaped clamps to move closer together inside the cylinder. Simultaneously, a limiting component allows the arc-shaped clamps to stop and fix at any position within the cylinder, thus achieving a clamping and fixing effect on the outer wall of the dropper. It can accommodate most droppers of different diameters, meeting the requirements of various experimental scenarios. It eliminates the need for multiple fixing devices for different droppers, improving experimental convenience. Furthermore, it provides stable support for the dropper, preventing reagent addition deviations due to unstable hand handling, ensuring more precise addition of auxiliary agents each time, and guaranteeing the accuracy of chemical reagent and auxiliary agent mixing.

[0016] 2. This chemical reagent and auxiliary agent mixing device allows the pawl to slide on the round rod and compress the second spring by pulling the handle upwards. This disengages the pawl from the ratchet, causing the drive disc to rotate in the opposite direction. The spring force of the first spring assists in the reverse rotation and reset, allowing the slide rod to disengage the arc-shaped clamp from the dropper, enabling quick disassembly and replacement of other chemical reagents and auxiliary agents. This helps improve the efficiency of chemical reagent and auxiliary agent mixing. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Referring to Figures 1-8, a chemical reagent and auxiliary agent mixing device includes: a stable base 1, a rectangular frame 2 and a beaker 18 disposed above the stable base 1, a plurality of cylinders 3 for fixing droppers are slidably connected on the rectangular frame 2, and a plurality of sliding rods 4 are slidably connected on the cylinders 3. Each sliding rod 4 is fixedly connected to an arc-shaped clamp 5 and a drive rod 6. The cylinders 3 are provided with a drive component 7 and a limiting component 8 corresponding to the drive rod 6. A first spring 28 is sleeved on the sliding rod 4, and the two ends of the first spring 28 abut against the drive rod 6 and the outer wall of the cylinder 3, respectively. The drive component 7 can control the sliding of the drive rod 6. The movement causes the sliding rod 4 to slide on the cylinder 3, which in turn causes multiple arc-shaped clamps 5 to move closer to each other inside the cylinder 3. At the same time, the limiting component 8 can stop and fix the arc-shaped clamps 5 at any position inside the cylinder 3, thereby achieving the effect of clamping and fixing the outer wall of the dropper. It can adapt to most droppers of different diameters and meet the requirements of droppers in different experimental scenarios. There is no need to prepare multiple fixing devices for different droppers, which improves the convenience of experiments. It can also provide stable support for the dropper, avoid reagent addition deviation caused by unstable hand, ensure more accurate addition of auxiliary agents each time, and ensure the accuracy of chemical reagent and auxiliary agent ratio.

[0029] A vertical plate 10 is fixedly connected to the top of the stable base 1. A cavity is opened inside the vertical plate 10, and a screw 11 is rotatably connected inside the cavity of the vertical plate 10.

[0030] A slider 12 is threaded onto the screw 11, one end of the rectangular frame 2 is fixedly connected to the slider 12, and a vertical groove 13 is provided on one side of the vertical plate 10.

[0031] A handwheel 14 is fixedly connected to the top of the screw 11. The handwheel 14 is rotatably connected to the vertical plate 10. An extension block 15 is fixedly connected to both sides of each cylinder 3. By rotating the handwheel 14, the screw 11 can be driven to rotate in the cavity of the vertical plate 10. The vertical groove 13 on one side of the vertical plate 10 can limit the movement trajectory of the slider 12. When the screw 11 rotates, the slider 12 can automatically drive the rectangular frame 2 to move up and down, thereby achieving the benefit of free adjustment of the height between the dropper and the beaker 18.

[0032] Two mounting ears 16 are fixedly connected to both ends of the rectangular frame 2, and guide rods 17 are fixedly connected between the two mounting ears 16. The extension block 15 is slidably connected to the guide rods 17. Through the guide rods 17 on the rectangular frame 2, the left and right positions of the dropper can be arbitrarily adjusted. With the help of the slider 12, the position of the dropper can be adjusted up, down, left and right at will, thereby increasing the convenience of chemical reagent and auxiliary agent preparation.

[0033] The driving component 7 includes an annular groove plate 19 fixedly connected to the outer wall of the cylinder 3. A driving disk 20 is rotatably connected inside the annular groove plate 19. The driving disk 20 has an arc-shaped sliding hole 21 adapted to the driving rod 6. The annular groove plate 19 can provide stable support for the driving disk 20, so that the driving disk 20 can rotate stably. When the driving disk 20 rotates, it will drive the arc-shaped sliding hole 21 to rotate at the same time, which will automatically cause the driving rod 6 to slide in the arc-shaped sliding hole 21, and drive the sliding rod 4 to slide on the cylinder 3. When the sliding rod 4 slides into the cylinder 3, it will compress the first spring 28. The first spring 28 helps to reset the sliding rod 4, the arc-shaped clamping plate 5, and the driving rod 6.

[0034] The limiting component 8 includes a ratchet 22 fixedly connected to the outer wall of the cylinder 3, a round rod 23 fixedly connected to the top of the drive disk 20, a pawl 24 rotatably connected to the round rod 23, and the pawl 24 slidably connected to the round rod 23.

[0035] A pull plate 25 is fixedly connected to the top of the pawl 24. A second spring 26 is sleeved on the round rod 23. A support plate 27 is fixedly connected to the top of the round rod 23. The two ends of the second spring 26 are fixedly connected to the support plate 27 and the pull plate 25, respectively. A baffle 9 is fixedly connected to the drive disc 20. By holding the support plate 27 and rotating it, the round rod 23 can be rotated, which in turn drives the drive disc 20 to rotate. At the same time, the pawl 24 will rotate along the ratchet 22. Under the action of the second spring 26, the pawl 24 will automatically slide and disengage from the ratchet 22. Under the action of the baffle 9, the pawl 24 can only rotate in one direction, which can automatically lock the drive disc 20, thereby automatically locking and fixing the dropper for stable chemical reagent mixing experiments. Through the baffle 9, the pawl 24 can only rotate in one direction, which can stably fix the drive disc 20 and make the dropper more stable during use.

[0036] In this invention, during the chemical reagent and auxiliary agent mixing experiment, the beaker 18 is placed on the stable base 1. Then, droppers containing chemical reagents and auxiliary agents are placed one by one into the appropriate positions inside the cylinder 3. Simply hold the support plate 27 and rotate it in one direction to cause the pawl 24 to twist, disengaging it from the ratchet 22. Simultaneously, the drive disc 20 rotates, causing the drive rod 6 to slide within the arc-shaped sliding hole 21. Each sliding rod 4 slides towards the center of the cylinder 3, clamping and fixing the droppers with the arc-shaped clamping plate 5. Releasing the support plate 27 then fixes the pawl 24 to the ratchet 22, preventing the drive disc 20 from rotating in the opposite direction. This automatically fixes the position of the sliding rod 4, stably clamping the droppers inside the cylinder 3. Then, chemical reagents and auxiliary agents are added to the beaker 18, and the process is completed via the rectangular frame 2. The guide rod 17 allows the cylinder 3 to slide the dropper left and right on the rectangular frame 2, facilitating position adjustment without moving the beaker 18. When adjusting the distance between the dropper and the beaker 18, simply turn the handwheel 14 to rotate the screw 11, causing the slider 12 to slide, which in turn moves the rectangular frame 2, thus adjusting the distance between the dropper and the beaker 18. When disassembling the dropper, simply hold the handle 27 and pull the pull plate 25 upwards to allow the pawl 24 to slide on the round rod 23 and compress the second spring 26, disengaging the pawl 24 from the ratchet 22. This allows the drive disc 20 to rotate in the opposite direction, and with the elastic force of the first spring 28 assisting in the reverse rotation and reset, the slide rod 4 can disengage the arc-shaped clamp 5 from the dropper, completing quick disassembly and rapid replacement of other chemical reagents and auxiliaries, which helps improve the efficiency of chemical reagent and auxiliary preparation.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
