[0026] This invention provides a multi-tube vortex mixer for biological experiments.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A multi-tube vortex mixer for biological experiments includes a fixed base 1, a vortex mixer fixedly connected inside the fixed base 1, a support plate 2 fixedly connected to the eccentric oscillating structure of the vortex mixer, a first soft pad 21 fixedly connected to the top of the support plate 2, and a test tube bottom placed on the first soft pad 21 to support the bottom of the test tube. The first soft pad 21 improves the protection effect on the bottom of the test tube.

[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5 The top of the fixed base 1 is fixedly connected to two fixed sliding rods 3, and a mounting frame 4 is slidably connected between the two fixed sliding rods 3. Multiple movable seats 5 are slidably connected inside the mounting frame 4. Side sliding grooves 41 are provided at both ends of the mounting frame 4, and connecting slides 6 are fixedly connected to both ends of the movable seats 5. The two connecting slides 6 are slidably connected inside the two side sliding grooves 41 respectively. The side sliding grooves 41 and connecting slides 6 are used to support the movable seats 5 to slide inside the mounting frame 4. Each movable seat 5 is provided with a slot 51. The slot 51 is V-shaped. By bringing the two movable seats 5 close to each other, the two slots 51 clamp and fix the outer wall of the test tube. The distance between the two movable seats 5 can clamp test tubes of different sizes. A second soft pad 52 is fixedly connected to the inner wall of the slot 51. The second soft pad 52 improves the protection effect on the outer wall of the test tube.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The mounting frame 4 is equipped with a limiting mechanism to restrict the sliding of the movable seat 5 inside the mounting frame 4. This limiting mechanism restricts the sliding of the movable seat 5 inside the mounting frame 4, thereby fixing the installation position of the movable seat 5. The limiting mechanism includes a connecting strip 11 fixed to the mounting frame 4, with multiple mounting holes 12 arranged in a linear array on the connecting strip 11. A movable insert rod 61 is slidably connected inside the connecting slide 6. One end of the movable insert rod 61 is inserted into the mounting hole 12. By pulling one end of the movable insert rod 61 out of the mounting hole 12, the movable seat 5 can slide freely inside the mounting frame 4. The seat 6 has an inner sliding groove 62 inside, and a fixing block 63 is fixedly connected inside the inner sliding groove 62. The movable insert rod 61 slides inside the fixing block 63. A baffle 64 is fixedly connected to the movable insert rod 61. The baffle 64 and the fixing block 63 are connected by a spring 65. Under the action of the fixing block 63 and the spring 65, the movable insert rod 61 can quickly slide upward and reset when no force is applied. This also increases the stability of one end of the movable insert rod 61 when it is inserted into the mounting hole 12. There are multiple sets of movable insert rods 61. The bottom of each set of movable insert rods 61 is fixedly connected by a connecting rod 66. The connecting rod 66 facilitates the downward sliding of two movable insert rods 61 together.

[0030] Please refer to it again. Figure 1 and Figure 6 Two fixed sliding rods 3 are each slidably connected to a second sleeve 73. A pressure plate 7 is provided between the two second sleeves 73. The pressure plate 7 includes a combination plate 71 hinged to the two second sleeves 73. The two combination plates 71 form the pressure plate 7 to press the top cover of the test tube. The two combination plates 71 are each provided with a connecting groove 72 at one end close to each other. A connecting strip 9 is inserted between the two connecting grooves 72. By pulling the connecting strip 9 out of the connecting groove 72, the connection between the two combination plates 71 is separated. By flipping the combination plate 71, it is easy to take the test tube on the mounting frame 4 for installation. A third soft pad 8 is fixedly connected to the bottom of the pressure plate 7. The third soft pad 8 is used to protect the top of the test tube when it is pressed.

[0031] Please refer to it again. Figure 1Two fixed sliding rods 3 are each slidably connected to a first sleeve 42. The mounting frame 4 is fixedly connected between the two first sleeves 42. By controlling the first sleeve 42 to slide on the fixed sliding rod 3, the installation height of the mounting frame 4 can be adjusted. The first sleeve 42 and the second sleeve 73 are both threadedly connected to fixing bolts. The fixed sliding rod 3 has a fixing hole that matches the fixing bolt. One end of the fixing bolt is inserted into the fixing hole. By rotating the fixing bolt, one end of the fixing bolt is turned into the fixing hole to fix the position of the first sleeve 42 or the second sleeve 73, thereby fixing the installation position of the pressure plate 7 or the mounting frame 4.

[0032] Working principle: After installing the device in a suitable position and connecting it to the municipal power supply, pull the connecting strip 9 out from between the two connecting slots 72, control the two combined plates 71 to flip and open the top of the mounting frame 4, then insert the test tube between the two slots 51. By pulling the connecting rod 66 downward, the two movable rods 61 are pulled out from inside the two combined plates 71, allowing the movable seat 5 to slide freely. The test tube is clamped and fixed by controlling the two slots 51. After adjustment, release the connecting rod 66, and under the action of the spring 65, the movable rods 61 will be inserted into the assembly. The interior of the composite plate 71 restricts the sliding of the movable seat 5. By adjusting the distance between each movable seat 5, test tubes of different sizes can be clamped and fixed. After fixing, the connecting strip 9 is inserted between the two connecting slots 72 by closing the two composite plates 71. By rotating the fixing bolt on the second sleeve 73, the fixing bolt is pulled out from the fixing hole. The second sleeve 73 is controlled to slide on the fixing slide rod 3, so that the pressure plate 7 is pressed on the top of the test tube. The position of the pressure plate 7 is fixed by the fixing bolt. Then the eccentric structure inside the vortex generator can be activated to vortex mix the test tube.
