[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Example 1:

[0027] Please see Figures 1-6The instrument shown in the diagram for mixing multiple EP tubes by oscillation includes a shaker 1, a control panel 2, and a handheld top cover 3. It also includes an oscillation interface 4 on the shaker 1, with a base post 7 inside the oscillation interface 4. A top post 13 is detachably mounted on the base post 7. Both the base post 7 and the top post 13 are made of stainless steel, a material with excellent corrosion resistance, suitable for various chemical reagent environments. Multiple retaining rings 8 are installed on both the base post 7 and the top post 13. A pipe rack 9 is detachably installed between multiple fixing rings 8 in a group; the fixing rings 8 can firmly fix the pipe rack 9 and will not loosen even under severe vibration. The pipe rack 9 is sleeved on the receiving base column 7 or the receiving upper column 13. The fixing rings 8 are threaded to the receiving base column 7 or the receiving upper column 13. There is also a storage component 5 installed on the receiving base column 7, which is used to store EP pipes; and a connecting component 6 installed on the receiving base column 7, which is used to connect the multi-layer pipe rack 9.

[0028] Furthermore, the storage component 5 includes mounting slots 27 evenly spaced within the pipe rack 9. Each mounting slot 27 contains a fixing pad 11 for securing the EP tube. The fixing pad 11 is made of silicone, which has good elasticity and flexibility, allowing it to tightly conform to the EP tube and adapt to its diameter, thus achieving stable fixation for EP tubes of different diameters. The inner diameter of the fixing pad 11 can be set according to the EP tube diameter, facilitating the placement of EP tubes of different diameters. Each mounting slot 27 has a rotatably connected handle 12 at its top, which is connected to the mounting plate via a pivot. The top edge of the mounting groove 27 is rotatably connected, and a damping device is provided at the pivot, so that the clamp 12 has a certain resistance during rotation, making it easy for the experimenter to control its opening and closing angle. Each clamp 12 is equipped with a tube rack cover 10, which can cover the mounting groove 27 to prevent the EP tube from falling off the tube rack 9. The inner side of the tube rack cover 10 is provided with a sealing ring. When the tube rack cover 10 covers the mounting groove 27, the sealing ring can fit tightly with the edge of the mounting groove 27 to form a sealing structure, effectively preventing the EP tube from falling off the tube rack 9 during vibration, and also preventing external dust and impurities from entering the mounting groove 27.

[0029] Furthermore, the connecting component 6 includes a connecting groove 14 formed on the receiving base post 7. The connecting groove 14 has symmetrical slots 15 that communicate with it. Each slot 15 has a top post 16 movably connected inside. The top post 16 can slide horizontally within the slot 15. In its natural state, the return spring 18 is in a relaxed state. Each of the two top posts 16 has a snap button 17 fixedly connected to its far end. Each of the two top posts 16 has a top block 19 fixedly connected to its near end. Each of the two top blocks 19 has an electromagnetic suction 20 installed at its near end.

[0030] Specifically: Both top posts 16 are fitted with return springs 18. The return springs 18 and compression springs 22 are made of stainless steel spring wire, which has good elasticity and fatigue resistance. They can maintain stable elasticity during long-term extension and contraction, ensuring the normal operation of the connecting parts 6. The ends of the two return springs 18 that are far apart from each other are fixedly connected to the snap button 17, and the ends of the two return springs 18 that are close to each other are fixedly connected to the receiving bottom post 7. By pressing the snap button 17, the top post 16 can be adjusted to squeeze the top block 19, which makes it easier to squeeze the locking block 24 on the receiving upper post 13 through the top block 19, thereby facilitating the disassembly of the receiving upper post 13.

[0031] Example 2:

[0032] This embodiment provides a further explanation of Example 1, based on... Figure 5 and Figure 6 As shown, it is worth noting that a protrusion 26 is engaged inside the connecting groove 14. The top of the protrusion 26 is fixedly connected to the receiving column 13. The protrusion 26 is cylindrical, and its outer diameter matches the inner diameter of the connecting groove 14, so that it can be tightly engaged inside the connecting groove 14. The protrusion 26 has symmetrically opened limiting grooves 21 inside. A compression spring 22 is installed inside each of the two limiting grooves 21. A limiting block 23 is installed at the ends of the two compression springs 22 that are far apart from each other. A locking block 24 is installed on the outside of each of the two limiting blocks 23. The size of the two locking blocks 24 corresponds to the locking groove 15.

[0033] Specifically, magnetic blocks 25 are installed on the side of the two card blocks 24 that are close to each other. The positions of the two magnetic blocks 25 correspond to the electromagnetic attractor 20. When the electromagnetic attractor 20 is energized, the magnetic blocks 25 are attracted, which helps to improve the stability of the connection between the bottom column 7 and the top column 13.

[0034] When it is necessary to connect the bottom support column 7 and the top support column 13, the protrusion 26 can be inserted into the connecting groove 14, and then the locking block 24 will automatically be inserted into the locking groove 15. At the same time, the electromagnetic suction 20 is activated through the control panel 2, which attracts the magnetic suction block 25, increasing the stability of the connection between the bottom support column 7 and the top support column 13. The connecting component 6 can adopt a multi-level joint assembly mode, increasing the number of EP tube racks 9 that can be used. At the same time, it can be quickly installed and disassembled, which is convenient for experiments and can reduce experimental data errors, thereby making it easier to achieve the expected accurate data results.

[0035] The principle behind this solution is as follows:

[0036] First, when the shaker 1 is started, the motor inside the shaker 1 transmits power to the shaking interface 4 through the transmission mechanism, causing the receiving bottom column 7 and the receiving upper column 13 to generate high-frequency oscillation motion. Since the EP tube is fixed to the receiving column by the fixing ring 8 and the tube rack 9, the EP tube will move synchronously with the oscillation of the receiving column, thereby achieving thorough mixing of the reagents in the tube. The control panel 2 is equipped with adjustment buttons for oscillation frequency, oscillation time, etc., allowing the experimenter to set appropriate oscillation parameters according to experimental needs and precisely control the oscillation process.

[0037] Secondly, when installing the pipe support 9, first place the pipe support 9 onto the supporting bottom column 7 or the supporting upper column 13, so that the annular flange of the pipe support 9 is located between the two retaining rings 8. Then rotate the retaining rings 8 at the bottom of the pipe support 9. When removing the pipe support 9, rotate the retaining rings 8 in the opposite direction, and then the pipe support 9 can be removed from the supporting column.

[0038] When it is necessary to place the EP tube, open the clamp 12 and place the EP tube into the mounting slot 27. Due to the good elasticity of the fixing pad 11, it will automatically adapt to the diameter of the EP tube and firmly fix the EP tube at the bottom of the mounting slot 27. Then close the clamp 12 so that the tube rack cover 10 covers the mounting slot 27, and the sealing ring fits tightly with the edge of the mounting slot 27, completing the storage of the EP tube.

[0039] Finally, when connecting the bottom support column 7 and the top support column 13, align the protrusion 26 at the bottom of the top support column 13 with the connecting groove 14 at the top of the bottom support column 7, and then press the top support column 13 down. During the insertion of the protrusion 26 into the connecting groove 14, the locking block 24 is squeezed by the inner wall of the connecting groove 14 and moves inwards towards the protrusion 26, compressing the compression spring 22. When the locking block 24 moves to the slot 15 position, under the elastic force of the compression spring 22, the locking block 24 automatically pops out and locks into the slot 15, achieving the initial connection between the bottom support column 7 and the top support column 13. At this time, the electromagnetic suction 20 is activated via the control panel 2. The electromagnetic suction 20 generates magnetism when energized, attracting the magnetic suction block 25, further enhancing the connection stability between the bottom support column 7 and the top support column 13.

[0040] When it is necessary to disassemble the upper support column 13, press the snap button 17. The snap button 17 pushes the top column 16 into the slot 15. The top column 16 presses against the top block 19. The top block 19 pushes the locking block 24 into the protrusion 26, and the compression spring 22 is compressed again. At the same time, the electromagnetic suction 20 is de-energized and loses its magnetism. After the locking block 24 is completely removed from the slot 15, the upper support column 13 can be removed from the lower support column 7.

[0041] It should be noted that the oscillator 1 and the electromagnetic attractor 20 are both equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.

Furthermore, under the teachings of this utility model, modifications to these features and embodiments can be made to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
