Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a shaking device suitable for different reagent tubes. Background Technology

[0002] In laboratory research in fields such as chemistry, biology, and medicine, vortex oscillators are an indispensable piece of routine equipment. Vortex oscillators are laboratory equipment used for fixing, shaking, and mixing reagents, solutions, and chemical substances, and are mainly used in medical, bioengineering, chemical, and pharmaceutical research fields.

[0003] A typical vortex shaker includes a main body, a shaking platform mounted on the main body, and a lifting frame. A test tube adapter is detachably mounted on the shaking platform. In use, the test tube is placed on the test tube adapter, and then the adapter is installed on the shaking platform. The main body is started, and the lifting frame presses down, pressing the test tube tightly into the adapter. Through the vibration of the shaking platform, the sample in the test tube is rapidly mixed, shaken, dissolved, or homogenized.

[0004] However, when attempting to place this combination of test tubes of varying heights on a conventional shaker, the holding device can only hold all the test tubes simultaneously on a single horizontal plane. This results in taller test tubes being firmly pressed down, while shorter test tubes may not be pressed down at all or the pressure may be insufficient.

[0005] Based on this, the present invention designs a shaking device applicable to different reagent tubes to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: the lifting frame includes a sponge pad, support frames symmetrically arranged on the machine body, and a stabilizing plate. The stabilizing plate is horizontally mounted between the two support frames. The stabilizing plate has several strip-shaped holes extending along a first direction. A pressing block is slidably arranged in the several strip-shaped holes. There is a preset height difference between the several pressing blocks. Several fixing frames are fixedly mounted on the stabilizing plate. The fixing frames have threaded holes. A screw is threaded into the threaded holes. The other end of the screw is fixedly connected to the pressing block.

[0007] By adopting the above technical solution, this invention, through the setting of a stabilizing plate with strip-shaped holes and a pressure block that can slide inside it, allows the operator to independently adjust the position of each pressure block according to the different heights of the test tubes, thereby adapting to and pressing test tubes of different heights in a row. Through the threaded engagement of the screw and the fixing frame, fine-tuning of the height of each pressure block and reliable locking and fixing are achieved, ensuring that all test tubes can be uniformly and stably pressed during high-speed oscillation, effectively preventing the test tubes from loosening, and greatly improving the safety of the oscillation device and its compatibility with test tube groups of different specifications.

[0008] Preferably, the bottom of the pressing block is provided with a limiting groove for accommodating the test tube cap.

[0009] By adopting the above technical solution, a limiting groove is opened at the bottom of the pressure block, which can accurately accommodate and lock the cap of the test tube. This design transfers the holding force from the side of the cap to the top of the cap, avoiding the test tube tilting that may be caused by lateral force, making the fixation of the test tube more stable and reliable, and also effectively preventing the cap from loosening and falling off during vibration.

[0010] Preferably, a sponge pad is adhesively provided at the bottom of the groove.

[0011] By adopting the above technical solution, the sponge pad can effectively prevent scratches on the surface of the test tube cap, protect the reagent tube, and the adhesive setting also makes it easy to replace the sponge pad, ensuring the protective effect of the sponge pad.

[0012] Preferably, the lifting frame includes at least one telescopic guide rod, the fixed end of which is connected to the bottom of the fixed frame, and the movable end of which is connected to the top of the pressing block.

[0013] By adopting the above technical solution, vertical guidance and additional support are provided for the up and down movement of the pressure block, preventing the pressure block from shaking or deflecting during adjustment or oscillation, ensuring the verticality and stability of the pressing action, and making the entire lifting frame structure more robust and its operation more stable.

[0014] Preferably, the test tube adapter is provided with a plurality of grooves, the cross-section of the grooves is trapezoidal and the inner wall of the groove is provided with anti-slip steps.

[0015] By adopting the above technical solution, the lower half of the test tube can be better wrapped and fixed. The trapezoidal groove can accommodate test tubes of different diameters. Together with the pressure block above, it achieves double restriction of the test tube at the top and bottom, which greatly improves the overall stability during the oscillation process.

[0016] Preferably, a knob is fixedly provided at the top end of the adjusting screw.

[0017] By adopting the above technical solution, operators can easily and effortlessly perform rotational adjustments without the need for tools, greatly improving the convenience and efficiency of operation.

[0018] In summary, this application has the following beneficial technical effects: By setting a stabilizing plate with strip-shaped holes and a pressure block that can slide inside it, the operator can independently adjust the position of each pressure block according to the different heights of the test tubes, thereby adapting to and pressing test tubes of different heights in a row. Through the threaded engagement of the screw and the fixing frame, fine-tuning of the height of each pressure block and reliable locking and fixing are achieved, ensuring that all test tubes can be pressed evenly and stably during high-speed oscillation, effectively preventing the test tubes from loosening, and greatly improving the safety of the oscillation device and its compatibility with test tube groups of different specifications.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] A shaking device suitable for different reagent tubes includes a body 1, a shaking platform 2 mounted on the body 1, and a lifting frame. The body 1 integrates a drive motor and control circuit. The shaking platform 2 is connected to the output shaft of the drive motor through an eccentric mechanism, which can generate vortex oscillation after startup. The surface of the platform is provided with a replaceable test tube adapter 5. The lifting frame includes a support frame 3 and a stabilizing plate 4 symmetrically mounted on the body 1. The stabilizing plate 4 is horizontally mounted between the two support frames 3. The stabilizing plate 4 has several strip-shaped holes 11 extending in a first direction. A pressure block 12 is slidably mounted in the several strip-shaped holes 11. There is a preset height difference between the several pressure blocks 12. Several fixing frames 6 are fixedly mounted on the stabilizing plate 4. The fixing frames 6 have threaded holes. A screw 9 is threadedly connected in the threaded holes. The other end of the screw 9 is fixedly connected to the pressure block 12.

[0025] In use, place test tubes of different heights into the adapter and rotate screw 9. Since screw 9 is threadedly connected to the fixing frame 6, rotation will push the connected pressure block 12 downward. The pressure block 12 itself has a height difference, which can simultaneously and naturally press the tube caps of different heights. The downward stroke of each pressure block 12 can be finely adjusted by knob 8 to ensure that all test tubes are pressed evenly. Set the oscillation speed and time, start the device, and the oscillation platform 2 will drive the test tubes to vortex oscillate. The lifting frame remains stationary, and the pressure block 12 on it is kept in a fixed position under the self-locking action of the adjusting screw 9, continuously providing stable downward pressure. After oscillation, rotate knob 8 in the opposite direction to raise the pressure block 12, and all test tubes can be removed.

[0026] The bottom of the pressing block 12 is provided with a limiting groove 13 for accommodating the test tube cap. A sponge pad 14 is glued to the bottom of the groove 10. After the pressing block 12 is pressed down, the top of the test tube abuts against the sponge pad 14. The two sides of the groove 10 limit the test tube, so that the test tube will not easily shake. The sponge pad 14 can effectively prevent scratches on the surface of the test tube cap and protect the reagent tube.

[0027] The lifting frame includes at least one telescopic guide rod 7. The fixed end of the telescopic guide rod 7 is connected to the bottom of the fixed frame 6, and its movable end is connected to the top of the pressure block 12. When the operator rotates the adjusting screw 9 to drive the pressure block 12 to rise or fall, the inner guide rod of the telescopic guide rod 7 performs precise axial telescopic movement within the outer sleeve, effectively preventing the pressure block 12 from radially swaying or deflecting during pressure or vibration, and ensuring the verticality and stability of the pressing action.

[0028] The test tube adapter 5 is provided with several grooves 10. The cross-section of the groove 10 is trapezoidal and the inner wall of the groove is provided with anti-slip steps 15. The trapezoidal structure makes the groove 10 have a guiding function, which makes it easy to insert the bottom of the test tube and center it. This tapered design allows a single groove 10 to fit test tubes of various diameters within a certain size range. When the test tube is inserted into the groove 10, the test tube wall can be embedded and locked in the anti-slip steps 15, which greatly increases the static friction between the test tube and the adapter and enhances the stability of the test tube placement.

[0029] A knob 8 is fixedly installed at the top of the adjusting screw 9. Rotating the knob 8 causes the screw 9 to rotate, and the limit block can move up and down quickly. This allows the operator to easily and effortlessly perform rotational adjustment without tools, greatly improving the convenience and efficiency of operation.

[0030] The implementation principle of this embodiment is as follows: When in use, test tubes of different heights are placed in the adapter. Rotating the knob 8 on the corresponding pressing block 12 drives the adjusting screw 9 to rotate, and the pressing block 12 moves downward. The inner guide rod of the telescopic guide rod 7 then performs precise axial telescopic movement within the outer sleeve. After the pressing block 12 is pressed down, the top of the test tube contacts the sponge pad 14. The two sides of the groove 10 limit the test tube, preventing it from easily shaking. The pressing blocks 12 themselves have a height difference, which can simultaneously and naturally press the caps of different heights. The pressing stroke of each pressing block 12 can be finely adjusted by the knob 8 to ensure that all test tubes are evenly pressed. After setting the oscillation speed and time, the device is started. The oscillation platform 2 drives the test tubes to perform vortex oscillation. The lifting frame remains stationary, and the pressing block 12 on it remains fixed in position under the self-locking action of the adjusting screw 9, continuously providing stable downward pressure. After the oscillation ends, the knob 8 is rotated in the opposite direction to raise the pressing block 12, and all test tubes can be removed.
