Description

Technical Field

[0001] The utility model relates to the technical field of mixing instruments, in particular to an oscillating mixing instrument. Background Technique

[0002] In the field of biotechnology, oscillating mixing instruments are usually used in experimental operations such as cell culture, cell extraction, DNA / RNA extraction, and enzyme reactions. It usually consists of a motor, an oscillator, a fixture, and a container. The motor provides power to drive the operation of the oscillating mixing instrument, generating a stirring effect through rotational or vibrational motion. The oscillator controls the frequency and amplitude of the oscillation, enabling the solution or suspension to be evenly mixed in the container. The fixture is used to fix the container to prevent it from sliding or tilting during the mixing process. It can quickly and effectively achieve the mixing, dissolution, and uniform dispersion of samples, improving the experimental efficiency and accuracy. In the existing device, the oscillation amplitude is fixed, and the oscillation amplitude of the device cannot be adjusted, which is not convenient for oscillating different samples, and the practicability is poor.

[0003] A constant-temperature oscillating mixing instrument (publication number: CN218475209U) is provided in the prior art. The device includes a mixing instrument box body. The top end of the mixing instrument box body is connected with a vibration platform through a driving mechanism. A mixing rack is placed on the top end of the vibration platform. The vibration platform and the mixing rack are connected through an installation mechanism. This application is more rapid and convenient compared with the traditional connection method of using multiple bolts to connect the vibration platform and the mixing rack. By operating the driving lever, the block can be made to lose its limit, so as to realize the disassembly of the mixing rack. The operation steps are simple and time-saving, and at the same time, the loosening problem caused by the bolt connection method is avoided. On the basis of facilitating connection and disassembly, the stability of the mixing rack during oscillation is ensured. At the same time, the power cord can be wound and placed, avoiding the disadvantage that the power cord is placed in a mess and not easy to access. Moreover, the embedded groove prevents the wound power cord from protruding excessively from the outer wall of the mixing instrument box body, making it more convenient for the overall storage of the device.

[0004] When the device is in use, the oscillation amplitude of the device cannot be adjusted. For example, different experimental samples may have different requirements for the oscillation amplitude. Some samples are more sensitive to a larger oscillation amplitude, while other samples may require a smaller oscillation amplitude. If the oscillation amplitude cannot be adjusted, the requirements of different experimental samples may not be met, resulting in damage to the samples or unsatisfactory experimental results. Therefore, we need to propose an oscillating mixing instrument. Content of the Utility Model

[0027] An oscillation assembly for cooperating with the adjusting assembly 4 is provided inside the base 1.

[0028] The oscillation assembly includes a moving plate 5 rotatably connected to the outside of the cam 41. The moving plate 5 is slidably connected to the base 1.

The output ends of two uniformly distributed telescopic rods 7 are fixedly connected to the side wall of the moving plate 5. The two telescopic rods 7 are fixedly connected to the base 1. Springs 8 are provided on the outer sides of the two telescopic rods 7.

[0029] Exemplarily, under the action of the cam 41, the moving plate 5 moves, and at the same time, under the action of the spring 8, it resets and moves back and forth left and right, playing an oscillating role on the upper test tube 13. When the moving plate 5 moves, the moving wheel 6 facilitates the movement of the moving plate 5, and the telescopic rods 7 play a guiding and limiting role.

[0030] A placing platform 9 is fixedly connected to the upper end of the moving plate 5. A mixing shell 10 is provided at the upper end of the placing platform 9.

[0031] Exemplarily, the placing platform 9 mounts the mixing shell 10.

[0032] A box cover 11 is provided at the upper end of the mixing shell 10. A placing plate 12 is fixedly installed inside the mixing shell 10.

[0033] Exemplarily, the box cover 11 seals the mixing shell 10, and the placing plate 12 facilitates the storage of the test tube 13.

[0034] A plurality of through holes are uniformly formed inside the placing plate 12. Test tubes 13 are slidably connected inside the plurality of through holes.

[0035] Exemplarily, the through holes facilitate the installation of the test tubes 13.

[0036] The upper end of the placement platform 9 is provided with a lifting assembly 14 for facilitating the removal of the test tubes 13. The lifting assembly 14 includes a double-shaft motor 141 fixedly installed on the placement platform 9.

The rotating motor 2 drives the cam 41 to rotate through the rotating rod 3. The cam 41 controls the position of the moving plate 5. Under the action of the cam 41, the moving plate 5 moves and at the same time resets under the action of the spring 8, performing left and right reciprocating movements, which plays an oscillating role on the upper test tubes 13. When different oscillation frequencies are required, the machine is stopped, and the knob 46 is rotated. The knob 46 drives the first lead screw 44 to rotate. A threaded movement occurs between the first lead screw 44 and the second fixed plate 45, controlling the movement of the second fixed plate 45.

When the sliding groove 42 moves, the first fixed plate 43 and the sliding groove 42 play a guiding role for the cam 41.

[0041] After the oscillation ends, the dual-axis motor 141 is turned on to drive the second screw 142 to rotate. Thread movement occurs between the second screw 142 and the internal thread block 144, controlling the internal thread block 144 to move away from the dual-axis motor 141. When the internal thread block 144 moves, it drives the articulated rod 145 to move.
