[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Figures 1 to 4 It is a schematic structural diagram of an adjustable rotating magnetic field generating device according to an embodiment of the present invention, the main body of which includes a magnetic field generating component 100, a driving device 200, a controller 300 and a base 400.

[0031] The magnetic field generating assembly 100 is used to generate a rotating magnetic field. Specifically, the magnetic field generating assembly 100 includes a mounting seat 110 and one or more rotating arms 120 extending radially outward along the peripheral wall of the mounting seat 110. Each of the rotating arms 120 is connected to a mounting arm 130, and the mounting arm 130 can move along the axial direction of the rotating arm 120. The rotating arm 120 is perpendicular to the mounting arm 130, and the bottom end of the mounting arm 130 is connected to an annular magnet 140. The culture dish is placed under the magnetic field generating assembly 100, and multiple rotating arms 120 enclose a space for placing the culture dish. When the annular magnet 140 rotates, a radial rotating magnetic field is generated toward the culture dish. In this embodiment, the outer wall of the upper end of each mounting arm 130 is provided with a through hole 130a adapted to the outer diameter of the rotating arm 120, and the top end of the rotating arm 120 is threadedly connected with a first adjusting bolt 150 for fixing the position of the mounting arm 130. When the first adjusting bolt 150 fixes the mounting arm 130 on the rotating arm 120, the end of the first adjusting bolt 150 abuts against the outer wall of the rotating arm 120. When the intensity of the rotating magnetic field needs to be adjusted, the first adjusting bolt 150 is first loosened to separate the end of the first adjusting bolt 150 from the outer wall of the rotating arm 120, and then the mounting arm 130 is pushed to move axially on the rotating arm 120 to move away from or close to the mounting seat 110 (away from or close to the culture dish), and finally the first adjusting bolt 150 is tightened to fix the mounting arm 130 on the rotating arm 120, thereby controlling the distance between the annular magnet 140 and the culture dish, thereby controlling the intensity of the rotating magnetic field and creating a platform for cell and animal modeling. Figure 5 As shown, a magnetic field simulation diagram generated by the rotating magnetic field generating device of the utility model.

[0032] Preferably, in this embodiment, more than one rotating arm 120 is symmetrically arranged at a certain angle on the outer peripheral wall of the mounting base 120, and the rotating arms 120 can be arranged in two, three or four, so as to make the rotating magnetic field more stable. In addition, the annular magnet 140 connected to the bottom end of one of the mounting arms 130 can also be removed and used as needed.

[0033] The controller 300 is located above the magnetic field generating assembly 100, and the driving device 200 is used as a power device to drive the mounting seat 110 to rotate synchronously, thereby driving the rotating arm 120, the mounting arm 130 and the annular magnet 140 to rotate synchronously with the axis of the mounting seat 110 as the center, forming a rotating magnetic field. In this embodiment, the driving device 200 is a motor, and the output shaft of the motor passes through the bottom shell of the controller 300 and then extends downward to connect with the top of the mounting seat 110. A display screen 310 and a control button 320 are provided on the front end shell of the controller 300. The control button 320 can adjust the speed of the motor, thereby controlling the magnetic field frequency, and the display screen 310 can display the number of revolutions of the motor.

[0034] Preferably, in the present embodiment, the bottom end of the rotating arm 120 is threadedly connected with a second adjusting bolt 160, and the peripheral wall of the second adjusting bolt 160 can be sleeved with more than one annular magnet 140. The second adjusting bolt 160 is used to fix the annular magnet 140 sleeved on the second adjusting bolt 160 on the rotating arm 120. At the same time, different numbers of annular magnets 140 can be sleeved on the second adjusting bolt 160 according to experimental requirements, so as to further adjust the strength of the rotating magnetic field. When the rotating arm 120 rotates, the annular magnet 140 and the second adjusting bolt 160 are in a tightly connected state, maintaining a synchronous rotation state with the rotating arm 120.

[0035] The top edge of the base 400 is connected with a support rod 410, which is located at the top edge of the base 400. Along the length direction of the support rod 410, the support rod 410 is slidably connected with a sliding seat 420 up and down. The outer wall of the sliding seat 420 is connected with a connecting rod 430 and a third adjusting bolt 440. The end of the connecting rod 430 is fixedly connected with the rear end housing of the controller 300. The third adjusting bolt 440 is threadedly connected with the sliding seat 420. When the third adjusting bolt 440 fixes the sliding seat 420 on the support rod 410, the end of the third adjusting bolt 440 abuts against the outer wall of the support rod 410. In the experiment, the heights of the culture dishes are all different. By adjusting the moving position of the sliding seat 420 on the support rod 410, the height of the controller 300 connected to the support rod 410 can be adjusted, so that the height of the magnetic field generating assembly 100 connected to the controller 300 from the culture dish can be adjusted. Multiple degrees of freedom can be adjusted to adapt to culture dishes of different heights.

[0036] Preferably, in this embodiment, a storage portion 500 is provided at the top of the base 400, and the top of the storage portion 500 is open for placing a culture dish. The storage portion 500 can be bonded to the top middle area of ​​the base 400 and located below the magnetic field generating assembly 100. Before the experiment is carried out, the culture dish is placed in the storage portion 500 to prevent the culture dish on the base 400 from shifting when the driving device 200 drives the magnetic field generating assembly 100 to move.

[0037] Combination Figures 1 to 5 , an adjustable rotating magnetic field generating device of this embodiment, the specific use process is as follows:

[0038] First, according to the height of the culture dish, the height of the controller 300 is adjusted, the culture dish is placed in the opening at the top of the storage portion 50, and the driving device 200 is started to drive the magnetic field generating assembly 100 to rotate as a whole, thereby generating a stable rotating magnetic field. When the magnetic field strength needs to be adjusted, the distance between the annular magnet 140 and the culture dish can be controlled by adjusting the axial movement of the mounting arm 130 on the rotating arm 120, or the number of annular magnets 140 sleeved on the second adjusting bolt 160 can be replaced, so that the strength of the rotating magnetic field can be adjusted according to the experimental requirements.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
