Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory equipment, and in particular to a test tube mixing device. Background Technology
[0002] The reason why reagents in test tubes need to be mixed during experiments is to ensure that the reagents react fully in order to obtain accurate experimental results. Reagent mixing is usually accelerated by shaking, stirring or agitation. Mixed reagents can react more quickly and evenly, thereby improving the efficiency and accuracy of the experiment.
[0003] Currently, the common practice for mixing reagents inside test tubes is to hold the test tube and shake it back and forth to mix them. However, when dealing with reagents that are difficult to mix or when preparing a mixture of reagents in multiple test tubes, the number of times the test tubes are shaken manually increases, which can easily lead to arm pain, high fatigue, and low efficiency. Utility Model Content
[0004] This disclosure relates to a test tube mixing device. Driven by a motor, the rotating frame rotates, which in turn drives the test tube rack to rotate around an axis, thereby achieving effective mixing of reagents inside the test tubes. The linkage shaft is driven to rotate by the meshing of a fixed gear and a moving gear. The rotation of the linkage shaft drives the test tube rack to rotate, thereby ensuring that the reagents inside the test tubes are fully mixed. This effectively shortens the time required for mixing reagents inside the test tubes and significantly improves mixing efficiency.
[0005] In a first aspect, this disclosure provides a test tube mixing device, specifically comprising: a support base, a motor, a rotating frame, a timing belt, a test tube rack, a manual screw, a linkage shaft, and a chain; the motor is externally mounted on the support base, and the timing belt is externally connected to the motor; the rotating frame is connected to the top of the support base, and the timing belt is connected to the rotating frame; the test tube rack is externally connected to the rotating frame, with test tubes located inside the test tube rack, and the manual screw is connected to the top of the test tube rack; the linkage shaft is externally connected to the rotating frame, with one end of the linkage shaft connected to the support base and the other end of the linkage shaft connected to the chain, which is connected to the test tube rack.
[0006] Furthermore, the test tube rack has a screw hole at the top, and a manual screw is threaded into the screw hole. A chuck is provided at the bottom of the manual screw, and the chuck contacts the test tube cap. When the test tube is placed inside the test tube rack, the manual screw is rotated to make the chuck and the test tube cap come into close contact, thereby achieving a stable clamping of the test tube.
[0007] Furthermore, a spring is fitted around the manual screw, with the top of the spring contacting the test tube rack and the bottom of the spring contacting the clamp. The spring increases the rotational resistance of the manual screw, effectively preventing the manual screw from loosening during use.
[0008] Furthermore, the rotating frame is equipped with a counterweight ball inside, and the rotating frame is rotatably connected to the support base. The test tube rack is also rotatably connected to the rotating frame. The addition of the counterweight ball ensures the stability of the rotating frame's rotation.
[0009] Furthermore, a small pulley is mounted on the drive shaft of the motor, and a large pulley is provided on the outside of the rotating frame. The small pulley is connected to the large pulley via a synchronous belt. Driven by the motor, the rotating frame can rotate, thereby driving the test tube rack to rotate around the axis, so as to achieve effective mixing of reagents inside the test tubes.
[0010] Furthermore, the linkage shaft is rotatably connected to the rotating frame, one end of the linkage shaft is provided with a moving gear, and the top of the support base is provided with a fixed gear, which meshes with the moving gear.
[0011] Furthermore, a large sprocket is provided at the bottom of the test tube rack, and a small sprocket is provided at the other end of the linkage shaft. The small sprocket is connected to the large sprocket via a chain. When the rack to be rotated rotates, the linkage shaft will be driven to rotate by the meshing of the fixed gear and the moving gear. The rotation of the linkage shaft will drive the test tube rack to rotate, thereby ensuring that the reagents inside the test tubes are fully mixed.
[0012] This invention provides a test tube mixing device, which has the following advantages: In use, after the test tube is placed inside the test tube rack, the manual screw is rotated to make the clamp and the test tube cap come into close contact, thereby achieving a stable clamping of the test tube and ensuring stability during the rotation and mixing of the test tube, preventing it from shaking or falling off. Furthermore, the use of a spring increases the rotational resistance of the manual screw, effectively avoiding the loosening of the manual screw during use, and further enhancing the reliability and safety of the test tube clamping.
[0013] In addition, the stability of the rotating frame is ensured by adding a counterweight ball; driven by a motor, the rotating frame rotates, which in turn drives the test tube rack to rotate around the axis, achieving effective mixing of the reagents inside the test tubes; while the rotating frame rotates, the linkage shaft is driven to rotate by the meshing of the fixed gear and the moving gear, and the rotation of the linkage shaft will drive the test tube rack to rotate, thereby ensuring that the reagents inside the test tubes are fully mixed, which can effectively shorten the time required for mixing the reagents inside the test tubes and significantly improve the mixing efficiency.

By adopting the above technical solution, after the test tube is placed inside the test tube rack 5, the manual screw 6 is rotated to make the clamp 61 make tight contact with the test tube cap, thereby achieving a stable clamping of the test tube, ensuring stability when the test tube is rotated and mixed, and preventing it from shaking or falling off; and the spring 7 is used to increase the rotational resistance of the manual screw 6, effectively avoiding the loosening phenomenon that may occur during the use of the manual screw 6, further enhancing the reliability and safety of the test tube clamping.
[0022] In this embodiment of the present disclosure, a counterweight ball 31 is provided inside the rotating frame 3, the rotating frame 3 is rotatably connected to the support base 1, the test tube rack 5 is rotatably connected to the rotating frame 3, a small pulley 21 is installed on the drive shaft of the motor 2, a large pulley 32 is provided outside the rotating frame 3, and the small pulley 21 is connected to the large pulley 32 through a synchronous belt 4.
