Description

Technical Field

[0001] The invention belongs to the technical field of teaching devices, and in particular relates to a double-blocking cell cycle operation teaching model. Background Art

[0002] When teaching cell cycle-related issues, in order to let students understand the specific cycle changes intuitively and specifically, it is generally necessary to use physical models to simulate the cell cycle state. In the double blocking experiment of 3H-TDR labeling with the cell cycle as the background, since the synchronization of the cell cycle involves the concept of life, scientific exploration, social responsibility and other investigations, the 3D model that can dynamically simulate various situations can effectively help students understand its principles;

[0003] However, the existing cell demonstration models are mostly simple in structure and function, and cannot help students understand the principles in complex situations. Students cannot understand the double blocking principle in a simple and profound way.

[0004] To this end, those skilled in the art have proposed a double-blocking cell cycle operation teaching model to solve the problems raised by the background technology.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to a person of ordinary skill in the art. Summary of the invention

[0006] The purpose of the present invention is to provide a double-blocked cell cycle operation teaching model to solve the problems raised in the background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A double-blocked cell cycle operation teaching model, including:

[0009] An installation mechanism, the installation mechanism comprises a bottom plate and a accommodating outer cover fixedly mounted on the upper surface of the bottom plate, a transparent top plate is arranged on the upper surface of the accommodating outer cover, a cell inlet is provided on the transparent top plate, a separation cylinder is fixedly mounted on the lower surface of the cell inlet, the separation cylinder has a circular cylinder structure, a slot is provided on the upper surface of the transparent top plate, the number of the slots is six, and a first latch, a second latch, a third latch, a fourth latch, a fifth latch and a sixth latch are respectively plugged into the six slots;

[0010] The driving mechanism includes a motor mounting base fixedly mounted on the upper surface of the base plate and a turntable arranged inside the accommodating outer cover, a driving motor is installed inside the motor mounting base, one end of the driving motor includes an output shaft, a connecting hole is opened on the lower surface of the turntable, the connecting hole is plugged into the output shaft, the cross-sectional shape of the turntable is trapezoidal, a plurality of partition tracks are arranged on the upper surface of the turntable, and the partition cylinder is located above the turntable.

[0011] Preferably, a cell outlet is provided on a peripheral side of the containing outer cover, the position of the fifth latch is adapted to the position of the cell outlet for blocking the cell outlet, and the sixth latch is located at one end of the fifth latch.

[0012] Preferably, the first latch and the fourth latch are located on the same central axis.

[0013] Preferably, a discharge groove is provided on the peripheral side of the separation cylinder, the position of the third latch is adapted to the position of the discharge groove for blocking the discharge groove, and the second latch is located at one end of the third latch.

[0014] Preferably, the first latch, the second latch, the third latch, the fourth latch, the fifth latch and the sixth latch all include a handle and a partition fixedly connected to the lower surface of the handle.

[0015] Preferably, a wiring port is provided on the peripheral side of the containing outer cover, and the wiring port is electrically connected to the driving motor.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention sets a driving motor to drive the turntable to rotate, and the separation cylinder on the transparent top plate can divide the turntable into two inner and outer circles. In the initial state, the first pin and the second pin are pulled out. At this time, the small ball used to simulate the cell enters the inner circle on the turntable from the cell inlet. The driving motor can drive the turntable to rotate. At this time, the first pin and the second pin are inserted, that is, the state when 3H-TDR is doped is simulated. At this time, the baffle will automatically close, so that the small ball is blocked and rolls into the pipeline due to gravity, indicating that some cells stay in the G1 / S phase. At the same time, the cells in the S phase are blocked by the baffle and stay still, indicating that the cells in the S phase directly terminate the cell process. At this time, the third pin is pulled out, and the fourth pin on the same central axis as the third pin is inserted. At this time, the balls enter the outer circle through the discharge groove. Since the fourth pin and the third pin are on the same central axis, the balls in the inner and outer circles will rotate at the same speed, which can simulate the state when 3H-TDR is washed away. At this time, the whole pipeline rotates along with the cylindrical inclined plane, so that the cells in the G1 / S phase that stay there can run the cycle together. Through this device, the cell cycle and the double blocking effect of 3H-TDR can be relatively simply and effectively represented, which is convenient for students to understand. Finally, after the demonstration is completed, the fifth pin can be pulled out to open the cell outlet to let the balls out.

[0018] (2) The present invention has the advantages of low cost, convenient and fast operation, high model accuracy and high quality by setting up 3D printing teaching equipment. Moreover, the teaching model made by 3D printing technology can break through the limitations of traditional teaching facilities and provide richer and more diverse teaching resources. If the model is damaged, it can even be easily remade, which is very suitable for use as a teaching aid.

[0026] Embodiment 1:

[0027] See also Figure 1-Figure 4 As shown, a double-blocked cell cycle operation teaching model includes:

A driving motor 18 is installed inside the motor mounting base 17. One end of the driving motor 18 includes an output shaft 19. A connecting hole 15 is opened on the lower surface of the turntable 14. The connecting hole 15 is plugged into the output shaft 19. The cross-sectional shape of the turntable 14 is trapezoidal. A plurality of partition tracks 16 are arranged on the upper surface of the turntable 14. The partition cylinder 12 is located above the turntable 14.

[0030] Specifically, a cell outlet 22 is opened on the side of the containing outer cover 2, the position of the fifth latch 9 is adapted to the position of the cell outlet 22 for blocking the cell outlet 22, and the sixth latch 10 is located at one end of the fifth latch 9.

The second latch 6 is located at one end of the third latch 7 .

[0033] As can be seen from the above, the device is provided with a driving motor 18 for driving the turntable 14 to rotate, and the separation cylinder 12 on the transparent top plate 3 can divide the turntable 14 into two inner and outer circles. In the initial state, the first latch 5 and the second latch 6 are pulled out. At this time, the small ball used to simulate the cell enters the inner circle on the turntable 14 from the cell inlet 4. The driving motor 18 can drive the turntable 14 to rotate.

At this time, the entire pipeline rotates along with the cylindrical inclined plane, so that the cells in the G1 / S phase that are retained can run the cycle together. Through this device, the cell cycle and the double blocking effect of 3H-TDR can be relatively simply and effectively represented, which is convenient for students to understand. Finally, after the demonstration is completed, the fifth pin 9 can be pulled out to open the cell outlet 22 to discharge the balls.
