Description

Technical Field

[0001] This utility model belongs to the field of test tube mixing technology, and more specifically, it relates to a multi-angle test tube oscillation mixing device. Background Technology

[0002] In experimental fields such as chemical, biological, and pharmaceutical research and development, shaking the test tube is an indispensable and crucial step in the experimental process to ensure sufficient contact, reaction, or uniform mixing of different liquid components. Therefore, a test tube shaking and mixing device is needed to mix reagents within the test tube. Existing test tube shaking and mixing devices mainly consist of a base, a test tube rack, and a driving device. The test tubes are placed inside the rack, and the driving device drives the rack to vibrate rapidly. This causes the liquids inside the test tubes to churn and convection violently, ultimately achieving the experimental effect of shaking and mixing.

[0003] Existing application number CN201922050349.7 discloses a rapid shaking and dissolving device for biochemistry. Its features include: a base, a support, a test tube shaking mechanism for holding multiple test tubes, a drive mechanism for driving the test tube shaking mechanism to reciprocate, and a control mechanism for controlling the start and stop of the drive mechanism. The support is fixedly mounted on the base, and the test tube shaking mechanism is movably connected to the support. The drive mechanism includes a cam, a speed-regulating motor, and a power supply. One side of the test tube shaking mechanism is connected to the rolling surface of the cam via a movable rod. A reset mechanism is provided between the movable rod and the cam. The axis of the cam is connected to the output shaft of the speed-regulating motor, and the speed-regulating motor is connected to the power supply. The control mechanism is connected to both the speed-regulating motor and the power supply. The advantage is that it enables automated and rapid shaking and dissolving of solutions in test tubes, improving the mixing efficiency of the solution.

[0004] Based on the above, the existing test tube shaking mixing devices mostly have fixed shaking angles, which are not convenient to adjust flexibly. In actual experiments, different types of reagents have significantly different requirements for mixing conditions. If the shaking angle is too large or the frequency is too high, some sensitive reagents may undergo component denaturation and internal active structure destruction due to violent impact. Conversely, if the shaking angle is too small or the frequency is insufficient, it is difficult to form sufficient liquid convection and shear force, which can easily cause uneven mixing of reagents and directly affect the reaction efficiency and the accuracy of experimental results. Utility Model Content

[0005] To address the aforementioned technical problems, this invention provides a multi-angle test tube oscillation mixing device. This addresses the issue that existing test tube oscillation mixing devices typically have fixed oscillation angles, making flexible adjustment inconvenient. In actual experiments, different types of reagents have significantly different mixing requirements. If the oscillation angle is too large or the frequency too high, some sensitive reagents may undergo component denaturation and internal active structure damage due to violent impact. Conversely, if the oscillation angle is too small or the frequency insufficient, it is difficult to generate sufficient liquid convection and shear force, easily leading to uneven reagent mixing and directly affecting reaction efficiency and the accuracy of experimental results.

[0006] The purpose and effectiveness of this multi-angle test tube oscillation mixing device are achieved by the following specific technical means:

[0007] A multi-angle test tube oscillation mixing device includes a mixing base, a support frame, a test tube rack, a limiting frame, a guide rail, a transmission frame, an adjustment component, and a support component. The support frame is fixedly installed on the upper part of the mixing base; the test tube rack is hinged inside the support frame; the limiting frame is fixedly installed inside the test tube rack; the guide rail is fixedly installed on one side of the support frame; the transmission frame is slidably connected inside the guide rail; the adjustment component is disposed inside the mixing base; and the support component is disposed inside the mixing base.

[0008] Furthermore, the adjustment assembly includes a drive motor and a transmission disk, wherein the drive motor is fixedly installed inside the mixing base; the transmission disk is rotatably connected to one side of the mixing base and is fixedly installed at one end of the drive motor.

[0009] Furthermore, the adjustment component also includes: a sliding groove, a limiting hole, and a driving protrusion, wherein the sliding groove is formed inside the transmission disk; the limiting hole is formed inside the transmission disk; and the driving protrusion is slidably connected inside the sliding groove.

[0010] Furthermore, the adjustment assembly also includes: a hinge shaft, a drive gear, and a drive rack. The hinge shaft is fixedly installed on the outside of the support frame and rotatably connected inside the support frame. The drive gear is fixedly installed at one end of the hinge shaft. The drive rack is fixedly installed inside the transmission frame, and the drive rack and the drive gear mesh with each other.

[0011] Furthermore, the adjustment assembly also includes a limit frame and a return spring, wherein the limit frame is fixedly installed on one side of the support frame; and the return spring is fixedly installed at the middle position at the bottom of the limit frame and the transmission frame.

[0012] Furthermore, the support assembly includes a threaded screw and a drive block, wherein the threaded screw is rotatably connected inside the mixing base; two sets of drive blocks are provided, and the two sets of drive blocks are slidably connected to each other at the bottom of the mixing base, and the two sets of drive blocks are threadedly connected to both ends of the threaded screw.

[0013] Furthermore, the support assembly also includes: guide posts, connecting rods, and support posts. Two pairs of guide posts are provided, and the two pairs of guide posts are fixedly installed at both ends of the bottom of the hybrid base. Two pairs of connecting rods are provided, with one end of each pair of connecting rods hinged to the bottom of the two sets of drive blocks, and the two pairs of connecting rods are slidably connected to the outside of the two pairs of guide posts. Two pairs of support posts are provided, and the two pairs of support posts are fixedly installed at the top of the two pairs of connecting rods.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, this invention features an adjustment component. A drive motor rotates the transmission disc, and a drive protrusion pushes the transmission frame to slide back and forth along a guide track, achieving continuous motion with the help of a return spring. The sliding of the transmission frame is transmitted through the meshing of a drive rack and drive gear, transforming it into the periodic oscillation of the test tube rack, thus achieving reagent mixing through oscillation. Simultaneously, by changing and fixing the position of the drive protrusion within the sliding groove, the stroke of the transmission frame can be flexibly adjusted, thereby changing the oscillation amplitude of the test tube rack. This satisfies the varying oscillation angle requirements of different reagents, avoiding uneven mixing or reagent damage caused by a fixed angle.

[0016] Secondly, this invention features a support assembly. By turning a threaded screw, two sets of drive blocks slide relative to each other. The traction connecting rod expands outward or retracts inward under the constraint of the guide column, causing the support column to expand or contract synchronously. When the oscillation amplitude is large, the support column expands outward to increase the contact area, improve the stability of the device, and prevent tipping and displacement. When not in use, the support column retracts to reduce the storage volume, facilitating storage and transportation, thus balancing experimental safety and ease of use.

[0017] This invention has the advantages of flexible adjustment, stable support, and convenient use. Through the flexible and adjustable oscillation angle design and the retractable support structure, it effectively solves the limitations of fixed parameters in traditional devices. It can not only adapt to the mixing requirements of different reagents, but also ensure the stability and ease of operation of the experimental process, making it more widely applicable.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides a multi-angle test tube oscillation mixing device, including a mixing base 1, a support frame 2, a test tube rack 3, a limiting frame 4, a guide rail 5, a transmission frame 6, and an adjustment component. The support frame 2 is fixedly installed on the upper part of the mixing base 1; the test tube rack 3 is hinged inside the support frame 2; the limiting frame 4 is fixedly installed inside the test tube rack 3; the guide rail 5 is fixedly installed on one side of the support frame 2; the transmission frame 6 is slidably connected inside the guide rail 5; and the adjustment component is disposed inside the mixing base 1.

[0029] The adjustment assembly includes a drive motor 101 and a transmission disk 102. The drive motor 101 is fixedly installed inside the mixing base 1. The transmission disk 102 is rotatably connected to one side of the mixing base 1 and is fixedly installed at one end of the drive motor 101.

[0030] The adjustment component also includes a sliding groove 103, a limiting hole 104, and a driving protrusion 105. The sliding groove 103 is formed inside the transmission disk 102; the limiting hole 104 is formed inside the transmission disk 102; and the driving protrusion 105 is slidably connected inside the sliding groove 103.

[0031] The adjustment assembly also includes: a hinge shaft 401, a drive gear 402, and a drive rack 601. The hinge shaft 401 is fixedly installed on the outside of the support frame 2 and is rotatably connected inside the support frame 2. The drive gear 402 is fixedly installed at one end of the hinge shaft 401. The drive rack 601 is fixedly installed inside the transmission frame 6, and the drive rack 601 and the drive gear 402 mesh with each other.

[0032] The adjustment assembly also includes a limit frame 106 and a return spring 602. The limit frame 106 is fixedly installed on one side of the support frame 2; the return spring 602 is fixedly installed at the middle position of the bottom of the limit frame 106 and the transmission frame 6.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In use, first place the test tubes to be processed into the test tube rack 3, and use the limiting frame 4 to stabilize and limit the upper part of the test tubes to prevent them from shifting during the oscillation process. When oscillation is required, start the drive motor 101. The motor output shaft drives the transmission disk 102 to rotate at a constant speed. The drive protrusion 105 on the transmission disk 102 moves synchronously in a circular motion, which in turn pushes the transmission frame 6 to slide back and forth along the guide rail 5. During this process, the guide rail 5 provides precise guidance for the transmission frame 6 to ensure its stable movement trajectory.

[0035] When the transmission frame 6 reciprocates, it simultaneously drives the return spring 602 to stretch and compress. When the driving protrusion 105 disengages from the pushing force on the transmission frame 6, the elastic restoring force of the return spring 602 assists the transmission frame 6 to quickly return to its original position, ensuring the continuity of the reciprocating motion. Simultaneously, the reciprocating sliding of the transmission frame 6 drives the internal driving rack 601 to reciprocate up and down. Since the driving rack 601 meshes with the driving gear 402, the linear motion of the rack is converted into the rotational motion of the driving gear 402, which in turn drives the hinge shaft 401 to oscillate back and forth. Finally, the test tube rack 3 oscillates periodically around the hinge shaft 401, achieving the oscillation and mixing of the reagents in the test tubes.

[0036] To adjust the oscillation angle, slide the drive protrusion 105 along the sliding groove 103 to the target position, then pass a bolt through the drive protrusion 105 and screw it into the corresponding limiting hole 104 to complete the fixation. The different positions of the drive protrusion 105 within the sliding groove 103 cause variations in the stroke of its driving transmission frame 6, ultimately resulting in differences in the swing amplitude of the test tube rack 3, thus achieving flexible adjustment of the oscillation angle.

[0037] Example 2:

[0038] Based on Example 1, such as Figures 1 to 5 As shown, it also includes a support assembly, which is disposed inside the hybrid base 1.

[0039] The support components include a threaded screw 701 and a drive block 702. The threaded screw 701 is rotatably connected inside the mixing base 1. Two sets of drive blocks 702 are provided, and the two sets of drive blocks 702 are slidably connected to the bottom of the mixing base 1. The two sets of drive blocks 702 are threadedly connected to both ends of the threaded screw 701.

[0040] The support assembly also includes: guide posts 704, connecting rods 703, and support posts 7. Two pairs of guide posts 704 are provided, and the two pairs of guide posts 704 are fixedly installed at both ends of the bottom of the hybrid base 1. Two pairs of connecting rods 703 are provided, and one end of the two pairs of connecting rods 703 is respectively hinged to the bottom of the two sets of drive blocks 702. The two pairs of connecting rods 703 are respectively slidably connected to the outside of the two pairs of guide posts 704. Two pairs of support posts 7 are provided, and the two pairs of support posts 7 are respectively fixedly installed at the top of the two pairs of connecting rods 703.

[0041] The specific usage and function of this embodiment are as follows:

[0042] When the swing amplitude of the test tube rack 3 increases, the centrifugal force and vibration impact force on the entire device will increase accordingly, which may easily lead to problems such as tipping, displacement, or decreased stability of the device. At this time, the stability of the device can be enhanced by adjusting the support components: a knob is provided at one end of the threaded screw 701. Turning the knob at one end of the threaded screw 701 drives the threaded screw 701 to rotate. Using the reverse thread structure at both ends of the screw, the two sets of drive blocks 702 are driven to slide synchronously relative to each other along the bottom of the mixing base 1.

[0043] When the drive block 702 moves, it synchronously pulls the connecting rod 703 to swing. Since the connecting rod 703 is slidably connected to the guide post 704 through a groove, under the limiting and guiding action of the guide post 704, the swinging connecting rod 703 will extend outward and maintain a stable posture. As the connecting rod 703 extends, the support post 7 at its top expands outward in sync, thereby effectively increasing the contact area between the device and the placement surface, significantly improving the overall support stability, and preventing swaying or tipping during oscillation.

[0044] When no oscillation mixing operation is required, the screw 701 can be turned in the opposite direction to make the drive block 702 slide towards each other, which will cause the connecting rod 703 and the support column 7 to retract inward, reducing the overall space occupied by the device and making it easier to store, transport and carry.
