[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0029] See also Figure 1-4 In the utility model, a biological culture device for biological experiments includes a box body 1, three fixed plates 2 are fixedly installed inside the box body 1, a group of placement holes are opened inside the fixed plate 2, a group of culture dishes 3 are movably installed on the fixed plate 2, the bottom ends of the culture dishes 3 pass through and extend to the outside of the placement holes, a rotating tube 4 is provided at the bottom of the fixed plate 2, one end of the rotating tube 4 passes through and is rotatably connected to the outside of the box body 1, a group of motors 5 are installed on the outside of the box body 1, the output end of the motor 5 is fixedly connected to one end of the rotating tube 4 through a coupling, a group of guide tubes 6 connected thereto are fixedly connected to the rotating tube 4, a telescopic part 7 is provided on the guide tube 6 that contacts the bottom of the culture dish 3, an air guide component 8 is provided inside the rotating tube 4, and an adjusting part 9 is provided between the fixed plate 2 and the culture dish 3.

[0030] In the present invention, the box body 1 is used to support the entire device, and the placement hole on the fixed plate 2 is used to place the culture dish 3. During the biological culture process, when the culture dish 3 needs to be shaken, the motor 5 can be started to drive the rotating tube 4 to rotate. During the rotation of the rotating tube 4, the telescopic member 7 will contact the bottom of the culture dish 3, causing it to shake up and down, and the user can use the air guide component 8 to adjust the length of the telescopic member 7 in advance according to the use requirements of the biological culture characteristics, change the resistance to the culture dish 3, and change the up and down shaking amplitude. At the same time, the setting of the adjustment member 9 can be used to make the culture dish 3 rotate and shake during the up and down shaking process.

[0031] See also Figure 1-3 , wherein: the telescopic member 7 includes a sliding rod 71 and a first piston plate 72, the outer side of the first piston plate 72 is slidably connected to the inside of the guide tube 6, one end of the sliding rod 71 is fixedly connected to the top of the first piston plate 72, and the other end of the sliding rod 71 is fixedly connected to the wear-resistant ball 10 that contacts the bottom of the culture dish 3.

[0032] The air guide assembly 8 includes an electric push rod 81 and a second piston plate 82. The electric push rod 81 is fixedly installed to the inside of the rotating tube 4. One end of the electric push rod 81 is fixedly connected to the outside of the second piston plate 82. The outside of the second piston plate 82 is slidably connected to the inside of the rotating tube 4.

[0033] Wherein: the bottom end of the guide tube 6 is installed with a micro electromagnetic valve 11 inside the rotating tube 4.

[0034] In the present invention, when the user needs to increase the shaking amplitude, the corresponding micro-solenoid valve 11 can be opened, and then the electric push rod 81 drives the second piston plate 82 to extend forward, so that the gas inside the rotating tube 4 is introduced into the corresponding guide tube 6. Then the gas will squeeze the corresponding first piston plate 72, so that the sliding rod 71 drives the wear-resistant ball 10 to move outward, so that when it contacts the bottom of the culture dish 3, the culture dish 3 can be pushed to a higher position. Then the micro-solenoid valve 11 is closed to complete the adjustment.

[0035] When the user needs to reduce the shaking amplitude, the corresponding micro solenoid valve 11 can be opened, and then the electric push rod 81 drives the second piston plate 82 to retract, thereby drawing the gas in the corresponding guide tube 6 back into the rotating tube 4. At this time, the corresponding first piston plate 72 is affected by the negative pressure, which will drive the wear-resistant ball 10 on the sliding rod 71 to move toward the direction of the rotating tube 4, so that the pushing position is lowered when it conflicts with the bottom of the culture dish 3, thereby reducing the shaking amplitude.

[0036] See also Figure 1-4, wherein: the adjusting member 9 includes two docking protrusions 91 and two docking grooves 92, the two docking protrusions 91 are symmetrically installed on the outside of the culture dish 3 along the center, the docking grooves 92 are opened to the inside of the fixed plate 2 and connected to the placement hole, and the docking protrusions 91 are movably connected to the inside of the docking grooves 92.

[0037] The cross-section of the docking groove 92 is wavy in front view, and the docking protrusion 91 and the culture dish 3 are connected by rotation.

[0038] In the present invention, after the culture dish 3 is resisted by the wear-resistant ball 10, it will move upward. During its movement, the docking protrusion 91 on the outside of the culture dish 3 will move along the wavy docking groove 92, causing the culture dish 3 to rotate left and right, increasing the shaking mode. Similarly, after the wear-resistant ball 10 is separated from the culture dish 3, when the culture dish 3 falls under the influence of gravity, the docking protrusion 91 on the outside will also reset along the wavy docking groove 92 again, and perform left and right rotation movement again.

[0039] See also Figure 1 , wherein: a fan connected to the interior of the box 1 is installed on the top of the box 1, and a light is installed on the inner wall of the box 1, one end of the light passes through and extends to the outside of the three fixed plates 2 in sequence.

[0040] In the utility model, the arrangement of the fan and the illumination lamp can ensure the ventilation performance and illumination performance of the biological culture environment, which is convenient for the growth of the organisms.

[0041] It should be noted that the various devices in this application are common devices in the market, and can be selected according to specific needs during specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection.
