[0004] The above-mentioned technical scheme is adopted to meet the use needs of personnel. Under the effect of overall coordination, the oscillator for cell preservation fluid can perform multiple effective oscillations during use, which greatly improves the effect of the oscillation operation and is convenient for personnel to use. However, the above-mentioned technical scheme does not have the function of adjusting the inner diameter size of the placement seat. When using test tubes of different diameters, it is necessary to replace placement seats of different diameters, which not only increases the cost of the laboratory, but also reduces the applicability of the cell preservation fluid oscillator.

[0005] Therefore, we proposed a cell preservation fluid oscillator to solve the above problems. Utility Model Content

At the same time, in the process of the clamps clamping the test tubes, the telescopic inner tube will be subjected to pressure and retract into the telescopic outer tube, causing the pressure measuring spring to retract at the same time.

Two moving blocks 5 are threadedly connected to the outer surface of the bidirectional threaded rod 4, and each moving block 5 is slidably connected to the inside of the placement seat 1. The outer surface of the L-shaped rod 14 is rotatably connected to a support block 15, and the left side surface of the support block 15 is fixedly connected to the inner wall of the outer shell 12. The support block 15 can increase the supporting points of the L-shaped rod 14, improve the firmness of the L-shaped rod 14, and prevent the possibility of the L-shaped rod 14 loosening after long-term use, thereby effectively increasing the service life of the L-shaped rod 14.

[0026] The outer surface of the bidirectional threaded rod 4 is fixedly connected to the anti-collision ring 6, the outer surface of the L-shaped rod 14 is rotatably connected to the transmission block 16, the interior of the transmission block 16 is rotatably connected to the sliding rod 17, the sliding rod 17 is slidably connected to the interior of the outer shell 12, and the transmission block 16 can transmit power, and can transmit the power generated by the L-shaped rod 14 during rotation to the sliding rod 17 through the transmission block 16, so that the sliding rod 17 has the ability to slide.

[0027] The inner wall of each moving block 5 is fixedly connected to two telescopic outer tubes 7, and the interior of each telescopic outer tube 7 is slidably connected to a telescopic inner tube 8. The interior of the sliding rod 17 is slidably connected to a stabilizing rod 19, and the inner top wall of the outer shell 12 is fixedly connected to a fixing plate 18. The left end of the stabilizing rod 19 is fixedly connected to the right side surface of the fixing plate 18, and the right end of the stabilizing rod 19 is fixedly connected to the inner wall of the outer shell 12. The stabilizing rod 19 can increase the force position of the sliding rod 17 during movement, improve the stability of the sliding rod 17 during movement, prevent the possibility of displacement of the sliding rod 17 during movement, and improve the stability of the device.

[0028] The inner wall of each telescopic outer tube 7 is fixedly connected with a pressure sensor 9, and each pressure sensor 9 is electrically connected to the servo motor 3 through a wire. The top of the sliding rod 17 is fixedly connected with a mounting bracket 20, and the inside of the mounting bracket 20 is rotatably connected with a rotating rod 21. The top of the rotating rod 21 penetrates the outer shell 12 and is fixedly connected to the bottom end of the placement seat 1. The rotating rod 21 is slidably connected to the inside of the outer shell 12. By utilizing the cooperation of the mounting bracket 20 and the rotating rod 21, the placement seat 1 can be able to rotate. The placement seat 1 can be driven to rotate by rotating the rotating rod 21, thereby improving the effect of the device during oscillation.

[0029] The ends of the two groups of telescopic inner tubes 8 that are away from each other are fixedly connected to pressure measuring springs 10, and the ends of the two groups of pressure measuring springs 10 that are away from each other are respectively fixedly connected to the side surfaces of the two groups of pressure sensors 9 that are close to each other.

[0030] The ends of the two sets of telescopic inner tubes 8 that are close to each other are fixedly connected with a clamping plate 11. The outer surface of the two-way threaded rod 4 is sleeved with an auxiliary bearing 24, and the auxiliary bearing 24 is embedded in the inside of the placement seat 1. The auxiliary bearing 24 can effectively reduce the power generated by the two-way threaded rod 4 during rotation, making the two-way threaded rod 4 more sensitive during rotation. At the same time, it can also reduce the wear rate of the two-way threaded rod 4 and increase the service life of the two-way threaded rod 4.

[0031] The working principle of the utility model is as follows: when in use, firstly, the test tube containing cells is placed in the placement groove 2, and then the servo motor 3 is started, and the power generated by the servo motor 3 is used to drive the bidirectional threaded rod 4 to rotate forward or reversely, and the auxiliary bearing 24 can increase the effect of the bidirectional threaded rod 4 during rotation, thereby making the two moving blocks 5 drive the clamping plates 11 to move closer to or away from each other, and when the clamping plates 11 contact the test tube, the telescopic inner tube 8 will drive the pressure measuring spring 10 to retract into the telescopic outer tube 7 due to the pressure, and at this time, the pressure sensor 9 can sense the pressure of the pressure measuring spring 10, and when the pressure reaches a preset value, send an electrical signal to the servo motor 3 through a wire, and stop it from running, thereby realizing the ability to fix test tubes of different diameters, and at the same time, it can also avoid excessive clamping pressure causing damage to the test tube or excessive pressure causing damage to the test tube.

When the L-shaped rod 14 rotates, it can make the sliding rod 17 move repeatedly inside the shell 12 through the cooperation of the transmission block 16. At this time, the stabilizing rod 19 and the fixing plate 18 can guide the moving direction of the sliding rod 17. The sliding rod 17 can drive the mounting frame 20 and the rotating rod 21 to move, so that the placement seat 1 is repeatedly moved. At the same time, the rotating rod 21 can drive the auxiliary gear 22 to move when it moves. When the auxiliary gear 22 moves, it can rely on the cooperation with the guide tooth block 23 to make the rotating rod 21 rotate, so that the placement table 1 rotates at the same time, which effectively improves the effect of the oscillation, not only reduces the cost of the laboratory, but also increases the applicability of the cell preservation fluid oscillator.
