Description

Technical Field

[0001] This utility model relates to the field of computer teaching technology, specifically a demonstration device for practical training based on computer applications. Background Technology

[0002] Computer applications study the theories, methods, technologies, and systems of applying computers to various fields. It is an interdisciplinary field that combines computer science with other disciplines and is a component of computer science itself. Computer applications provide guidance on how to participate in and implement computer activities in society. As computer technology becomes increasingly prevalent in our lives, mastering knowledge related to computer applications is becoming increasingly important.

[0003] Because existing training devices use a single screen for explanation and can only display one interface and course at a time, it is quite troublesome when they need to be integrated with other teaching projects.

[0004] To address this, a demonstration device for practical training based on computer applications is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a computer-based demonstration device for practical training and teaching, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A computer-based training demonstration device includes a table and a display screen assembly, with a support column installed on the top of the table.

[0008] The support column is equipped with a clamp, and guide rails are provided between the clamps;

[0009] The display screen group includes a main screen and two secondary screens;

[0010] The main screen is fixedly connected to the guide rail;

[0011] The secondary screen is slidably connected to the guide rail via a linkage structure, and the secondary screen is rotatably connected to the linkage structure.

[0012] Furthermore, the top of the support column is provided with an upper support plate for placing some teaching materials.

[0013] Furthermore, the tabletop is equipped with legs at the bottom, and a connecting plate is provided between the bottom ends of the legs to maintain stability, so that the whole device remains stable, which is beneficial for practical training and teaching.

[0014] Furthermore, the linkage structure includes a guide block, a connecting frame, and a connector;

[0015] The guide block is slidably connected to the guide rail, and one end of the guide block is hinged to the connecting frame. The other end of the connecting frame is hinged to the connector, and the connector is fixed to the sub-screen, so that the sub-screen can be adjusted horizontally along the guide rail for easy use. At the same time, the sub-screen can also be rotated to adjust the angle.

[0016] Furthermore, the support column is divided into two parts, a lower part and an upper part, and the clamp is fastened to the upper part.

[0017] Furthermore, the lower part is hollow inside and equipped with an electric telescopic rod. The output end of the electric telescopic rod is connected to the upper part, which can adjust the height of the secondary screen and the main screen for convenient teaching.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model adopts a multi-screen design, which can be connected to a computer host for teaching at the same time. Each screen can play the teaching and training projects separately, which is convenient to use.

[0020] The secondary screen of this invention adopts a horizontal and rotational adjustment design, which can adjust the position of the secondary screen without affecting the use of the main screen, and facilitates multi-screen playback. Attached Figure Description

[0021] Figure 1 This is a three-dimensional structural diagram of the present invention;

[0022] Figure 2 This is a schematic diagram of the main structure of this utility model;

[0023] Figure 3 This is a schematic diagram of the guide rail structure of this utility model. Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1:

[0026] Please see Figure 1-3 This utility model provides a technical solution:

[0027] A computer-based training demonstration device includes a tabletop 2 and a display screen assembly. A support column 3 is installed at the top of the tabletop 2 to support the display screen assembly. A clamp 4 is installed on the support column 3, and a guide rail 9 is installed between the clamps 4. The display screen assembly includes a main screen 7 and two secondary screens 8. The main screen 7 is fixedly connected to the guide rails 9 as the main display screen. The secondary screens 8 are slidably connected to the guide rails 9 through a linkage structure, allowing the secondary screens 8 to be horizontally adjusted. The secondary screens 8 are rotatably connected to the linkage structure, allowing the direction and angle of the secondary screens 8 to be adjusted.

[0028] like Figure 1 As shown:

[0029] An upper support plate 5 is installed at the top of the support column 3, which can hold some teaching supplies. At the same time, for the stability of the device, a support leg 1 is installed at the bottom of the table 2, and a connecting plate 6 is installed between the bottom ends of the support leg 1 to maintain stability.

[0030] like Figure 2 As shown:

[0031] The linkage structure includes a guide block 10, a connecting frame 11, and a connector 12. The guide block 10 is slidably connected to the guide rail 9, so that the guide block 10 can drive the sub-screen to move and adjust horizontally. The guide block 10 is hinged to one end of the connecting frame 11, and the other end of the connecting frame 11 is hinged to the connector 12. The connector 12 is fixed to the sub-screen 8, so that the sub-screen 8 can be rotated and adjusted. It can be rotated and adjusted not only relative to the connecting frame 11, but also relative to the guide block 10, which facilitates multi-angle adjustment of the sub-screen 8.

[0032] The support column 3 is divided into two parts: a lower part 31 and an upper part 32. The clamp 4 is fastened to the upper part 32. The lower part 31 is hollow inside, and an electric telescopic rod is installed there. The output end of the electric telescopic rod is connected to the upper part 32. The electric telescopic rod is used to adjust the height of the screen.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
