Description

Technical Field

[0001] This utility model relates to the field of stirring rods, and more particularly to a multifunctional stirring rod for chemical experiments. Background Technology

[0002] Chemical laboratory stirring rods are tools used in laboratories to mix and stir liquids or solid-liquid mixtures. They are widely used in chemical, biological, pharmaceutical, and materials science fields, and are mainly used to accelerate experimental operations such as dissolution, mixing, emulsification, and suspension. Stirring rods are indispensable tools in the laboratory, and through proper selection and use, they can significantly improve experimental efficiency and the reliability of results.

[0003] Existing stirring rods, which use an integrated stirring rod connected to a motor for stirring, cannot be adjusted according to the depth and shape of containers used in experiments to hold solutions. This results in the stirring rod being too long or too short, making it difficult to fully stir the solution in the container, reducing the overall mixing effect and affecting the accuracy of the experiment.

[0004] Therefore, regarding the existing stirring rods, since the experimental process requires the use of containers of different depths and sizes to store solutions for stirring, the use of an integrated stirring rod cannot be adjusted according to the depth and shape of the container. This results in the stirring rod being too long or too short, making it difficult to fully stir the solution in the container, reducing the overall mixing effect, and affecting the accuracy of the experiment. A multifunctional stirring rod for chemical experiments can be designed, with its length adjustable according to the experimental stirring requirements to adapt to containers of different depths and sizes. This avoids uneven stirring or inconvenience caused by the stirring rod being too short or too long, ensuring that the liquid can be fully mixed during the stirring process, and meeting the multifunctional stirring requirements under different experimental conditions. Utility Model Content

[0006] The technical solution of this utility model is as follows: a multifunctional stirring rod for chemical experiments, including a fixed column, an adjusting rod, a limiting rod, a connecting frame, and a connecting plate. The adjusting rod is installed at one end of the fixed column, and a movable groove for accommodating the adjusting rod is opened inside the fixed column. The adjusting rod is movably arranged along the inside of the fixed column. A connecting frame is provided at one end of the adjusting rod, and a threaded head is installed on the inner wall of the connecting frame. The connecting frame is threadedly fixed to the adjusting rod through the threaded head.

[0007] Preferably, the fixed column is equipped with a limiting rod inside, and the limiting rod is symmetrically equipped with pins. The adjusting rod is fixed to the fixed column by inserting the limiting rod.

[0008] Preferably, the adjusting rod has multiple sets of receiving holes for accommodating the limiting rod, and the limiting rod has a receiving hole for accommodating the pin, which is then inserted and fixed to the limiting rod.

[0009] Preferably, the upper end of the connecting frame is circumferentially welded with several sets of separating rods, one end of which is fixed with a fixing sleeve, and the inside of the fixing sleeve is provided with a connecting hole to accommodate the adjusting rod.

[0010] Preferably, a connecting plate is installed at one end of the fixed column, and multiple sets of limiting bolts are circumferentially installed on the outer end of the connecting plate.

[0011] Preferably, the connecting plate is fixed by welding, and multiple sets of limiting bolts extend through the connecting plate into the interior.

[0012] Preferably, a monitoring module is installed at the end of the fixed column away from the adjusting rod, and the monitoring module is fitted into the fixed column.

[0013] The beneficial effects of this utility model are:

[0014] Compared to traditional stirring rods, this device allows for precise insertion into containers of varying depths and sizes by adjusting the length of the adjusting rod according to experimental stirring needs. This avoids uneven mixing or operational inconvenience caused by a rod that is too short or too long, ensuring thorough mixing of the liquid. It meets the multi-functional stirring requirements under different experimental conditions. The threaded head allows for the replacement of different connecting frames to flexibly adapt to various experimental needs. It is suitable for liquids of different viscosities, densities, and volumes, improving stirring efficiency and effectiveness. A monitoring module tracks the rotation speed and number of revolutions of the stirring rod, enabling researchers to precisely control stirring conditions, optimize experimental conditions, better control reaction rates and mixing effects, and improve experimental accuracy.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a multifunctional stirring rod for chemical experiments, including a fixed column 1, an adjusting rod 2, a limiting rod 3, a connecting frame 5, and a connecting plate 9. The adjusting rod 2 is installed at one end of the fixed column 1, and the fixed column 1 has an internal groove for accommodating the adjusting rod 2. The adjusting rod 2 is movably arranged along the interior of the fixed column 1. The connecting frame 5 is provided at one end of the adjusting rod 2, and a threaded head 8 is installed on the inner wall of the connecting frame 5. The connecting frame 5 is threadedly fixed to the adjusting rod 2 through the threaded head 8.

[0022] Please see Figures 1-3 In this embodiment, the fixed column 1 is provided with a limiting rod 3 inside, and pins 4 are symmetrically installed on the limiting rod 3. The adjusting rod 2 is fixed to the fixed column 1 by inserting it through the limiting rod 3. After the length of the adjusting rod 2 is adjusted, it is fixed by limiting it with the limiting rod 3 to prevent the adjusting rod 2 from loosening or shifting due to vibration or external force during the stirring process, thereby improving the stability of the stirring process. The adjusting rod 2 has multiple sets of receiving holes for accommodating the limiting rod 3 inside, and the limiting rod 3 has a receiving hole for accommodating the pin 4 inside. The pin 4 is inserted and fixed to the limiting rod 3. By using the pin 4 to assist in the firm limiting of the limiting rod 3, it is prevented from falling off during the rotation process, thus ensuring the stable conduct of the stirring experiment.

[0023] Please see Figures 2-3 In this embodiment, the upper end of the connecting frame 5 is circumferentially welded with several sets of separating rods 6, and one end of each set of separating rods 6 is fixed with a fixing sleeve 7. The fixing sleeve 7 has a connecting hole for accommodating the adjusting rod 2. One end of the fixing column 1 is equipped with a connecting plate 9, and the outer end of the connecting plate 9 is circumferentially equipped with several sets of limiting bolts 10. By using the connecting plate 9 in combination with the limiting bolts 10 to assist the fixing column 1 in connecting and installing with the motor, it is ensured that the stirring rod will not loosen or shift during high-speed rotation, providing stable connection support.

[0024] Please see Figures 2-4In this embodiment, the connecting plate 9 is fixed by welding, and multiple sets of limiting bolts 10 extend through the connecting plate 9 into the interior. A monitoring module 11 is installed at the end of the fixed column 1 away from the adjusting rod 2. The monitoring module 11 is fitted into the fixed column 1. By using the monitoring module 11 to monitor the rotation speed and number of revolutions of the stirring rod, multi-functional stirring work is achieved, which makes it easier for experimental personnel to accurately control the stirring conditions, optimize the experimental conditions, better control the reaction rate and mixing effect, and improve the accuracy of the experiment.

[0025] During operation, firstly, adjust the length of the adjusting rod 2 according to the experimental stirring requirements to adapt to containers of different depths and sizes. This ensures the stirring rod can accurately reach into the container for stirring, avoiding uneven stirring or operational inconvenience caused by the stirring rod being too short or too long. This ensures thorough mixing of the liquid during stirring. After adjusting the adjusting rod 2 along the inside of the fixed column 1, insert the limiting rod 3 into the inside of the fixed column 1 to limit and fix it, preventing the adjusting rod 2 from loosening or shifting due to vibration or external force during stirring. Secondly, insert the pin 4 into the inside of the limiting rod 3 for secondary fixation. After the adjusting rod 2 is adjusted and fixed, use a threaded head... 8. Different connecting frames 5 can be replaced according to stirring requirements to flexibly adapt to various experimental needs. It is suitable for liquids with different viscosities, densities and volumes, and meets the multi-functional stirring needs under different experimental conditions. After the separation rod 6 is installed, multiple sets of limit bolts 10 are used to assist the connection plate 9 in connecting to the motor to ensure that the monitoring module 11 is electrically connected to the motor and provides stable connection support. The adjusting rod 2 is placed in the designated container, and the motor is started to drive the adjusting rod 2 to rotate and stir. At the same time, the monitoring module 11 monitors the rotation speed and number of revolutions of the stirring rod, which makes it easy for the experimenters to accurately control the stirring conditions, optimize the experimental conditions, and achieve stable chemical experiments.

[0026] Through the above steps, by adjusting the length of the regulating rod 2 according to the experimental stirring requirements, it can adapt to containers of different depths and sizes, allowing the stirring rod to accurately extend into the container for stirring. This avoids uneven stirring or inconvenience caused by the stirring rod being too short or too long, ensuring that the liquid is fully mixed during the stirring process. It meets the multi-functional stirring requirements under different experimental conditions. By using the threaded head 8 to replace different connecting brackets 5 according to stirring requirements, it can flexibly adapt to various experimental needs and is suitable for liquids of different viscosities, densities, and volumes, improving stirring efficiency and effect. The monitoring module 11 monitors the rotation speed and number of revolutions of the stirring rod, allowing experimenters to accurately control stirring conditions, optimize experimental conditions, better control reaction rate and mixing effect, and improve experimental accuracy.
