Computer engineering experimental demonstration devices are specially designed experimental tools designed to help students gain a deeper understanding of the theoretical knowledge of computer science and related engineering fields through hands-on operation and observation.

[0003] Experimental demonstration videos can be displayed using display devices. However, when playing videos on a monitor, teachers need to pause the video to highlight key points. Frequent pausing makes it difficult for viewers to quickly grasp the general content of the video. Additionally, dust can accumulate on the monitor surface over time, affecting its display. Therefore, it is necessary to propose a computer science engineering experiment demonstration device. Utility Model Content

The drive gear drives the rack to move outward, and the rack drives the second display to move outward, placing the second display outside the first display. This increases the display area of ​​the first display. As the second display moves outward, the first cleaning brush cleans the surface of the second display. After the second display moves outside the first display, the... Two springs push the circular pusher block into the loop block, limiting the loop block's position. When the second display screen moves back inside the first display screen, it drives the loop block to move inward. The loop block then drives the second cleaning brush to clean the first display screen. The number of display devices can be increased or decreased as needed. The sub-screen displays the key points of the demonstration video, eliminating the need for teachers to frequently stop the video to focus on the key points. This allows viewers to quickly grasp the general content of the video. The first and second cleaning brushes can be used to clean the first and second displays, preventing dust from adhering to their surfaces and affecting their use. Attached Figure Description

[0023] Please see Figure 1-9This utility model provides a technical solution: a computer engineering experimental demonstration device, including a first outer shell 1, a support frame 2, and a cleaning mechanism 3. A first display 4 is fixedly connected to the inner wall of the first outer shell 1. A support frame 2 is fixedly connected to one outer wall of the first outer shell 1. A second outer shell 5 is symmetrically slidably connected to the upper surface of the support frame 2. A second display 6 is fixedly connected to the inner wall of the second outer shell 5. A rotating rod 7 is rotatably connected to the upper surface of the support frame 2. A drive gear 8 is fixedly connected to the outer wall of the rotating rod 7. A rack 9 is fixedly connected to one outer wall of the second outer shell 5. The drive gear 8 meshes with the rack 9. A T-shaped mounting groove is provided on one outer wall of the first outer shell 1. One end of the second outer shell 5 extends into the T-shaped mounting groove.

[0024] The cleaning mechanism 3 includes a herringbone block 31. The outer wall of the first housing 1 is symmetrically connected to the herringbone block 31. A first mounting groove is opened through one side of the outer wall of the herringbone block 31. A first cleaning brush 32 is slidably connected to the inner wall of the first mounting groove. The first cleaning brush 32 abuts against the second display 6. A cavity is opened through the inside of the herringbone block 31. A conical block 33 is slidably connected to the inner wall of the cavity. A limiting hole 34 is opened through the outer wall of the first housing 1 relative to the position of the conical block 33. The conical block 33 extends through into the limiting hole 34. A first spring 35 is fixedly connected to the inner top wall of the cavity. The other end of the first spring 35 abuts against the conical block 33, so that the first spring 35 can be used to push the conical block 33 into the limiting hole 34.

[0025] The outer wall of the second outer shell 5 has a through-hole for mounting cavity relative to the position of the U-shaped block 31. A circular push block 10 is slidably connected to the inner wall of the mounting cavity. A second spring 11 is fixedly connected to one side of the inner wall of the mounting cavity. The other end of the second spring 11 abuts against the circular push block 10, so that the second spring 11 can be used to push the circular push block 10 into the cavity and push the conical block 33 out of the limiting hole 34.

[0026] The inner wall of one side of the herringbone block 31 is provided with a second mounting groove, and the inner wall of the second mounting groove is slidably connected to a second cleaning brush 12. A threaded hole 13 is provided through the outer wall of one end of the herringbone block 31. One end of the threaded hole 13 extends through into the first cleaning brush 32 and the second cleaning brush 12 and is threadedly connected to a fixing bolt 14. One end of the fixing bolt 14 extends out of the threaded hole 13 and is fixedly connected to a handle 15, so as to facilitate the use of the fixing bolt 14 to limit and fix the first cleaning brush 32 and the second cleaning brush 12.

[0027] The lower surface of the support frame 2 is fixedly connected to a drive motor 16, and the output end of the drive motor 16 is fixedly connected to the rotating rod 7 through a coupling, so that the drive motor 16 can drive the rotating rod 7 to rotate.

[0028] Among them, the lower surface of the support frame 2 is symmetrically fixedly connected with T-shaped frames 17, and the lower surfaces of the two T-shaped frames 17 are symmetrically fixedly connected with rotating wheels 18. The rotating wheels 18 are set as universal wheels, which facilitates the movement of the device by using the rotating wheels 18.

[0029] The outer walls of both sides of the first outer shell 1 are fixedly connected with blocking blocks 19, which facilitates the use of blocking blocks 19 to limit the movement of the loop block 31.

[0030] Specifically, when using this utility model, the first display 4, the second display 6, and the drive motor 16 are all connected to an external drive source via a controller. The device is moved to the desired position by rotating the wheel 18. The first display 4 can then be turned on to play a computer engineering experiment demonstration video. Starting the drive motor 16 drives the rotating rod 7 and the drive gear 8 to rotate. The drive gear 8 drives two racks 9 to move to both ends. As the racks 9 move, they simultaneously drive the second display 6 to move outwards, moving it outwards from the inside of the first display 4. This adds two secondary screens to the demonstration device. The first display 4 plays the computer engineering experiment demonstration video, while the second display 6 displays the key experimental points. Before using the second display 6, the loop block 31 can be moved to both sides of the first outer shell 1. The first spring 35 pushes the conical block 33 into the limiting hole 34, fixing the loop block 31 in place. When the second display 6 moves outwards, it passes the loop block 31, and the second display 6 on one side of the loop block 31... The cleaning brush 12 cleans the surface of the second display 6, removing dust. When the second display 6 is fully unfolded, the second spring 11 pushes the circular push block 10 into the cavity and pushes the conical block 33 upward. The conical block 33 moves out of the limiting hole 34. After the first display 4 and the second display 6 are used, the drive motor 16 is started to drive the rotating rod 7 and the drive gear 8 to rotate in opposite directions. The drive gear 8 drives the rack 9 and the second display 6 to move inward. The second display 6 drives the loop block 31 to move inward through the circular push block 10. The loop block 31 uses the first cleaning brush 32 to clean the surface of the first display 4. The handle 15 can be used to remove the fixing bolt 14 from the threaded hole 13. The first cleaning brush 32 and the second cleaning brush 12 are taken out of the loop block 31 and cleaned. After cleaning, the first cleaning brush 32 and the second cleaning brush 12 are inserted into the loop block 31, and the handle 15 is used to turn the fixing bolt 14 into the threaded hole 13.
