[0028] Among them, the motor 3 is also equipped with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.
[0029] In the above embodiments, springs and clamping blocks located inside the test tube openings are also provided in conjunction with the first placement plate 6 and the second placement plate 7. The springs and clamping blocks can fix the test tube after it is placed inside the test tube openings. For details, please refer to the prior art with announcement number CN212855584U. Since it is not the main structure of this solution, it is not described or shown in detail in this article.
[0030] The second rotating shaft 5 has two synchronization grooves 10 inside, and the outer surface of the first rotating shaft 4 is fixedly connected to two synchronization blocks 11. The two synchronization blocks 11 are slidably connected inside the two synchronization grooves 10 respectively.
[0031] The sliding frame 2 has a rotating groove 15 inside the horizontal plate. The second rotating shaft 5 is fixedly fitted with a connecting ring 16 at one end inside the rotating groove 15. The connecting ring 16 is rotatably fitted inside the rotating groove 15.
[0032] The linkage assembly includes two connecting plates 12, both of which are fixedly connected to the upper surface of the horizontal plate of the mounting bracket 1. The two connecting plates 12 are respectively rotatably sleeved on the outer surface of the two support shafts 8. A first bevel gear 13 is fixedly sleeved on the outer surface of the first rotating shaft 4. A second bevel gear 14 is fixedly sleeved on the opposite end of the two support shafts 8. The two second bevel gears 14 are meshed with the first bevel gear 13.
[0033] The two vertical plates of the mounting bracket 1 each have a sliding groove 17 on one side of their respective surfaces. Guide rods 18 are fixedly connected inside the two sliding grooves 17. Guide blocks 19 are fixedly connected to both sides of the sliding bracket 2. The two guide blocks 19 are slidably connected inside the two sliding grooves 17 and slidably sleeved on the outside of the two guide rods 18.
[0034] A first square rod 20 is fixedly connected to the lower surface of the second placement plate 7. A second square rod 21 is slidably sleeved inside the first square rod 20. The lower end of the second square rod 21 extends slidably out of the interior of the first square rod 20 and is fixedly connected to the upper surface of the first placement plate 6.
[0035] The second square rod 21 has a positioning groove 22 inside, and the first square rod 20 has a positioning rod 23 slidably sleeved inside. Both ends of the positioning rod 23 extend out of the interior of the first square rod 20. The positioning rod 23 and the positioning groove 22 are matched. A tension spring 24 is fixedly connected between the positioning rod 23 and the outer surface of the first square rod 20. The tension spring 24 is movably sleeved on the outside of the positioning rod 23.
[0036] In the above embodiment, since the positioning rod 23 is inserted deep into the positioning groove 22 and the tension spring 24 always provides a pushing force to the positioning rod 23, when the two placement plates rotate, the positioning rod 23 will not be dislodged from the interior of the positioning groove 22 due to inertia, thereby ensuring the stability of the height of the second placement plate 7.
[0037] The lower surface of the mounting bracket 1 is fixedly connected to two support legs 25.
[0038] Working principle: The operator places the test tubes to be mixed into the test tube openings of the first placement plate 6 and the second placement plate 7, and fixes the test tubes with the help of springs and clamping blocks. Then, the switch of motor 3 is turned on. The rotation of the output shaft of motor 3 drives the rotation of the first rotating shaft 4. The rotation of the first rotating shaft 4, together with the cooperation of the synchronization block 11 and the synchronization groove 10, drives the rotation of the second rotating shaft 5. The rotation of the second rotating shaft 5 drives the rotation of the first placement plate 6. The rotation of the first placement plate 6 drives the rotation of the second square rod 21. The rotation of the second square rod 21 drives the rotation of the first square rod 20. The rotation of the first square rod 20 drives the rotation of the second placement plate 7, thus achieving the rotation of the test tubes.
[0039] Simultaneously, during the rotation of the first rotating shaft 4, the first bevel gear 13 will rotate synchronously. Through the rotation of the first bevel gear 13 and the cooperation of the two second bevel gears 14, both support shafts 8 will rotate. The rotation of the support shafts 8 will drive the rotation of the cams 9 on both sides. Since the cams 9 are fixedly sleeved on the eccentric part of the support shaft 8, the rotation of the cams 9 can lift the sliding frame 2, thereby enabling the sliding frame 2 to reciprocate up and down. Furthermore, when the sliding frame 2 moves, it will drive the guide block 19 to slide inside the sliding groove 17. When the sliding frame 2 moves up and down, the cooperation of the connecting ring 16 and the rotating groove 15 will drive the second rotating shaft 5 to move up and down. At this time, the second rotating shaft 5 will slide on the outer surface of the first rotating shaft 4, and the synchronizing block 11 will slide inside the synchronizing groove 10. Finally, the up and down movement of the second rotating shaft 5 will drive the first placement plate 6 and the second placement plate 7 to move up and down, thereby realizing the up and down oscillation of the test tube.
[0040] In addition, the staff can pull the positioning rod 23 outward to disengage it from the inside of the positioning groove 22, and then let the first square rod 20 slide outside the second square rod 21, thereby adjusting the height of the second placement plate 7. Subsequently, the positioning rod 23 is released to insert it into the inside of the positioning groove 22, so that the distance between the two placement plates is adapted to the height of the test tube.
[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
