[0021] like Figure 1 As shown, this solution is mainly used for electrical practical training and improves upon the shortcomings of existing teaching tools. Specifically, it includes the following features: 1. Demonstration board 1, as attached Figure 1 To be continued Figure 4 As shown, the demonstration board 1, as the main component of the entire teaching aid, is composed of two boards for easy storage, and is attached to... Figure 1 It can be seen that the upper first display panel 11 and the lower second display panel 12 are simultaneously attached. Figure 1 It can be seen that the first display plate 11 and the second display plate 12 are rotatably connected by a connecting shaft on the contact surface. As can be seen from the attached figure, this embodiment is a vertical folding, and similarly it can also be set to a horizontal folding. In order to lock the first display plate 11 and the second display plate 12 after they are opened, as can be seen from the attached figure, the first locking member 13 is provided on the left and right sides of the connection between the first display plate 11 and the second display plate 12. After opening, it locks and prevents shaking. If it is a folding design on the left and right, the first locking member 13 should be provided on the upper and lower sides of the connection. In cases of teaching interruptions during break times or for other reasons, it is necessary to protect the already connected electrical circuits. This application incorporates a protective device, as shown in the attached document. Figure 7 With appendix Figure 8As shown, a dustproof mounting groove 16 is provided above the front of the first display board 11 and the second display board 12. Matching dustproof clips 71 are provided on the left and right sides of the dust cover 7. The dust cover 7 can cover the front of the demonstration board 1 through the dustproof clips 71, thereby playing a protective role. When teaching needs to continue, the dust cover 7 can be lifted up and removed, which is convenient and quick.

[0022] Meanwhile, in order to lock the first display panel 11 and the second display panel 12 after they are combined, locking buckles 17 and locking slots 18 are respectively provided on the first display panel 11 and the second display panel 12, so that they can be locked after they are combined.

[0023] Meanwhile, the first display panel 11 and the second display panel 12 are respectively provided with a first handle 14 and a second handle 15. After the first display panel 11 and the second display panel 12 are combined, the first handle 14 and the second handle 15 are combined to form a handle that can be lifted, making it convenient to lift and move.

[0024] II. Demonstration rail 2, as attached Figure 1 With appendix Figure 5 As shown, the device is used to move the demonstration equipment and is mainly set on the front of the demonstration board 1. Specifically, it includes several horizontally parallel horizontal moving guide rails 21 and several horizontally parallel vertical moving guide rails 22. The horizontal moving guide rails 21 and the vertical moving guide rails 22 are interconnected and used to move the demonstration equipment. At the same time, multiple vertical placement guide rails 23 are connected below each horizontal moving guide rail 21, thereby fulfilling the functions of moving and limiting the demonstration equipment. At the same time, a guide rail inlet 24 is provided on at least one transverse moving guide rail 21 to facilitate the entry of the instrument.

[0025] III. Electrical installation components 6, as attached Figure 1 With appendix Figure 6 As shown, the electronic components used for teaching are installed. Therefore, in order to install them, the surface of the electrical mounting device 6 is an electrical mounting plate 61. Several bolt through slots are provided on the surface of the electrical mounting plate 61, so that the electronic components can be installed on the electrical mounting plate 61 by bolts. At the end of the electrical mounting plate 61, there is a snap-fit ​​sliding post 62. Since the demonstration track is U-shaped, the snap-fit ​​sliding post 62 is provided with a snap-fit ​​inner groove 63, so that it can be snapped into the demonstration track and slide. After the bolts are installed, the other side of the electrical mounting plate 61 will be higher. Therefore, in order to make the electrical mounting plate 61 fit the demonstration board 1, increase stability, and prevent the bolts from causing jamming, the side of the electrical mounting plate 61 near the snap-fit ​​sliding column 62 is concave. This prevents the bolts from protruding and ensures that the electrical mounting plate 61 fits the demonstration board 1.

[0026] IV. Component storage assembly 4, as shown in the attached document Figure 2 With appendix Figure 3 As shown, the device storage assembly 4 is used to store the electrical installation device 6. Considering that the demonstration board 1 needs to be folded and merged, and to avoid being restricted after merging, the device storage assembly 4 is set in the inner groove on the back of the demonstration board 1. It mainly consists of several placement guide rail slots 41, which are T-shaped in the attached figure. Similarly, they can also be L-shaped. At the same time, there should be an insertion port. In this design, the insertion port is located in the middle position. The structure of the placement guide rail slots 41 is the same as the structure of the demonstration track. A second locking member 42 is provided on the placement guide rail slots 41. After being inserted, it is locked, thereby reaching the limit and realizing the storage of the electrical installation device 6. When in use, the second locking member 42 is released, the electrical installation device 6 slides upward and can be taken out from the insertion port for direct use.

[0027] V. Cable organizer 3, as attached Figure 2 As shown, similar to the device storage component 4, considering that the demonstration board 1 needs to be folded and merged to avoid being restricted after merging, the connecting wire storage component 3 is also set in the inner groove on the back of the demonstration board 1. It is mainly composed of several storage slots and is used to store the connecting wires.

[0028] VI. Retractable support frame 5, as attached Figure 2 With appendix Figure 7 As shown, the retractable support frame 5 includes two parts: an H-shaped support frame 51 and a ground support block 52. A corresponding insertion hole is provided at the lower end of the demonstration board 1. The H-shaped support frame 51 is inserted into the insertion hole to complete the support. At the same time, the ground support block 52 is set below the H-shaped support frame 51 to increase the support area and make it more stable. When not in use, a support frame placement slot 53 and a support block placement slot 55 are provided on the back of the demonstration board 1. Two or more elastic tightening straps 54 are provided outside the support frame placement slot 53 for placing the H-shaped support frame 51. The middle position of the H-shaped support frame 51 is a telescopic rod to reduce its volume. Similarly, the two sides can also be telescopic rods. The support block placement groove 55 is used to place the ground support block 52. A third locking element 56 is provided on the support block placement groove 55 to lock and limit the bottom support block.

[0029] The first locking component 13, the second locking component 42, and the third locking component 56 mentioned above are all snap-on designs, which are simple to edit. Similarly, other locking components can also be used, such as the elastic tightening band 54 mentioned above or Velcro, etc.

[0030] During teaching, the mounting bases, which hold electrical components such as buttons and circuit breakers, are moved flexibly between the upper and lower plates via a guide rail structure. After confirming the position, wiring demonstrations can be conducted.

[0031] If teaching is temporarily interrupted during the teaching process, the existing wiring electrical circuit can be protected by dust cover 7.

[0032] At the end of the teaching period, the teaching aids can be folded and stored to reduce space occupation and facilitate quick transportation of the entire set of teaching aids according to changes in teaching location.

[0033] This technical solution also allows for the complete storage of electrical components and the addition of teaching aids for wiring components, and is easy to transfer to various teaching locations. The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
