Description

Technical Field

[0001] The utility model relates to the technical field of educational demonstration tools, in particular to a sex chromosome combination demonstration device. Background Art

[0002] Human somatic cells have 22 pairs of autosomes and one pair of sex chromosomes, for a total of 46 chromosomes. The autosomes are identical in males and females, but the difference lies in the 23rd pair of sex chromosomes, which are different in males and females: XY and XX, respectively. Current teaching methods often use images or videos to help students understand the differences in the 23rd pair of sex chromosomes, but they lack the ability to actually experience them. The impact of the 23rd pair of chromosomes on gender makes it difficult for students to grasp. Utility Model Content

[0003] The utility model provides a sex chromosome combination demonstration device, which is intended to demonstrate the matching relationship between sex chromosomes and gender.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A sex chromosome combination demonstration device comprises a horizontally arranged transparent drum and vertically arranged side supports on a demonstration platform. Both ends of the transparent drum are rotatably connected to the side supports. A detection switch is provided above the transparent drum, between the side supports. An X chromosome simulation block and X and Y chromosome simulation blocks are placed in a receiving cavity of the transparent drum. When the X chromosome simulation block and the upper side surfaces of the X and Y chromosome simulation blocks form different chromosome combinations after the transparent drum is rotated, the detection switch turns on the relevant circuit in the indicator light.

[0006] In the above scheme, an X chromosome simulation block and X and Y chromosome simulation blocks are placed in the receiving cavity of the transparent drum. A detection switch is provided above the transparent drum between the side supports. When the transparent drum rotates, when the X chromosome simulation block and the upper side surfaces of the X and Y chromosome simulation blocks form different chromosome combinations, the detection switch turns on the relevant circuit in the indicator light, thereby demonstrating the matching relationship between sex chromosomes and gender.

[0012] like Figures 1 to 5 A sex chromosome combination demonstration device is shown. A demonstration platform 1 is provided with a horizontally arranged transparent drum 10 and vertically arranged side supports 20. The two ends of the transparent drum 10 are rotatably connected to the side supports 20. A detection switch 21 is provided above the transparent drum 10, between the side supports 20. An X chromosome simulation block 30 and X and Y chromosome simulation blocks 40 are placed within a receiving cavity 11 of the transparent drum 10. When the upper side surfaces of the X chromosome simulation block 30 and the X and Y chromosome simulation blocks 40 form different chromosome combinations after the transparent drum 10 is rotated, the detection switch 21 turns on the relevant circuit in the indicator light 50.

[0013] In the above scheme, the demonstration platform 1 is provided with a horizontally arranged transparent drum 10 and a vertically arranged side support 20. The receiving cavity 11 of the transparent drum 10 contains an X chromosome simulation block 30 and X and Y chromosome simulation blocks 40. When the transparent drum 10 is rotated, the upper surfaces of the X chromosome simulation block 30 and the X and Y chromosome simulation blocks 40 form different chromosome combinations. The detection switch 21 activates the relevant circuits in the indicator light 50 based on the combination of the upper surfaces of the X chromosome simulation block 30 and the X and Y chromosome simulation blocks 40. The detection switch 21 can be a color detection switch. When the transparent drum 10 is rotated, the detection switch 21 activates the relevant circuits in the indicator light 50 based on whether the colors of the upper surfaces of the X chromosome simulation block 30 and the X and Y chromosome simulation blocks 40 are the same or different.

[0014] Of course, to indicate an equal probability of sex chromosome combinations XX and XY, the X chromosome simulation block 30 and the X / Y chromosome simulation blocks 40 are preferably cube blocks. Xs are engraved on all six sides of the X chromosome simulation block 30, while Xs or Ys are symmetrically engraved on the six sides of the X / Y chromosome simulation blocks 40. The detection switch 21 can be a photoelectric detection switch. The X side of the X chromosome simulation block 30 and the X / Y chromosome simulation blocks 40 have the same brightness, while the Y side of the X chromosome simulation block 30 and the X / Y chromosome simulation blocks 40 have different brightness. After the transparent drum 10 rotates, the detection switch 21 activates the relevant circuit in the indicator light 50 based on whether the brightness of the upper side of the X chromosome simulation block 30 and the X / Y chromosome simulation blocks 40 are the same or different.

[0015] Furthermore, the indicator light 50 includes a first indicator light 51 and a second indicator light 52 on the demonstration platform 1. When the brightness of the upper side of the X chromosome simulation block 30 and the X, Y chromosome simulation block 40 is the same or different, the relevant circuit in the first indicator light 51 or the second indicator light 52 is turned on.

[0016] In the above solution, the first indicator light 51 and the second indicator light 52 are engraved with the words "male" and "female". When the brightness of the upper side of the X chromosome simulation block 30 and the upper side of the X and Y chromosome simulation blocks 40 are the same, the relevant circuit of the first indicator light 51 is turned on and illuminated. When the brightness is different, the relevant circuit in the second indicator light 52 is turned on and illuminated.

[0017] Furthermore, the Y surface of the X / Y chromosome simulation block 40 is a light-emitting surface, and the detection switch 21 is a photoelectric switch connected in series to the circuit between the power supply and the first indicator light 51 and the second indicator light 52. When the detection switch 21 does not receive light from the Y surface of the X / Y chromosome simulation block 40, the detection switch 21 closes to the first indicator light 51, powering on the first indicator light 51 and lighting up the first indicator light 51. When the detection switch 21 receives light from the Y surface of the X / Y chromosome simulation block 40, the detection switch 21 closes to the second indicator light 52, powering on the second indicator light 52 and lighting up the second indicator light 52.

[0018] Furthermore, to ensure that the X chromosome simulation block 30 and the X and Y chromosome simulation blocks 40 do not interfere with each other, the accommodating chamber 11 of the transparent drum 10 includes a first accommodating chamber 11 and a second accommodating chamber 12 arranged adjacent to each other. The X chromosome simulation block 30 and the X and Y chromosome simulation blocks 40 are respectively located in the first accommodating chamber 11 and the second accommodating chamber 12.

[0019] Preferably, in order to facilitate the user to shake the transparent drum 10 , a bent shaking handle 60 is installed at one end of the transparent drum 10 .

[0020] Furthermore, in order to ensure that the X chromosome simulation block 30 and the X and Y chromosomes have one side facing upward after shaking, which is convenient for detection by the detection switch 21, the outer cross-section of the transparent drum 10 of the simulation block 40 is circular, and the inner cross-section is a regular pentagon.
