[0025] like Figures 1 to 5 As shown, the utility model provides an electrical and electronic experiment teaching platform, including a main box body 1, which is rectangular as a whole, and a box cover 2 of adapted size is rotatably connected to one side of the upper end surface of the main box body 1 for opening and closing the main box body 1, and a plurality of mounting grooves 3 are provided on the upper end surface of the main box body 1 (the number of mounting grooves 3 is at least 11, and the width of each mounting groove 3 is changed according to the actual installed module size), and an active cavity 9 is provided below each mounting groove 3 inside the main box body 1. The active cavity 9 is U-shaped as a whole, and a downward pressure port 10 is provided in the middle of the active cavity 9, which passes through the main box body 1 and is connected to the mounting groove 3. At the same time, side grooves 11 are provided at both ends of the U-shape of the active cavity 9, which pass through the main box body 1 and are connected to the mounting groove 3.

[0026] like Figure 1 、 2 As shown, multiple installation slots 3 are fixed with sockets 6 at the bottom, and the connection terminals of the sockets 6 pass through the bottom of the main box 1 and are connected to the external power supply system. Electronic modules 7 that are connected to the sockets 6 are movably connected in the grooves of multiple installation slots 3. At the same time, snap-in slots 8 are provided on both sides of the electronic module 7 at positions aligned with the side slots 11, and the width of the snap-in slots 8 is consistent with the width of the side slots 11.

[0027] like Figure 2 、 3As shown in FIG. 5 , the fixing mechanism 4 includes a force-bearing block 41 inserted into the movable cavity 9 by the lower pressure port 10. The top of the force-bearing block 41 is conical, and the conical surface of the force-bearing block 41 protrudes from the bottom surface of the mounting groove 3 under normal conditions. The movable cavity 9 is located on both sides of the force-bearing block 41 and is rotatably connected with a rotating plate 44, and the ends of the two rotating plates 44 facing each other are in contact with the bottom of the force-bearing block 41. The ends of the two rotating plates 44 away from the force-bearing block 41 are rotatably connected to each other. The two limit blocks 45 are L-shaped as a whole, and the middle part of the limit block 45 is movably connected with a rotating rod fixed to the inner wall of the movable cavity 9, thereby forming the rotation of the limit block 45. Both ends of the U-shaped inner wall of the movable cavity 9 are rotatably connected with the clamping blocks 46. The tops of the two clamping blocks 46 are conical, and the conical surfaces are aligned with the side grooves 11. Under normal conditions, the conical surfaces of the clamping blocks 46 are flush with the notches of the side grooves 11. At the same time, the bottom of the clamping block 46 forms a clamping connection with the limit block 45 (such as Figure 3 shown).

[0028] It should be noted that a fixing groove 42 is provided on the side surface of the force-bearing block 41 located in the active cavity 9, and a first spring 43 is fixed to the bottom of the force-bearing block 41. The first spring 43 is fixed to the bottom surface of the active cavity 9 on the other side relative to the force-bearing block 41. At the same time, the two clamping blocks 46 are fixed to the opposite side surfaces with second springs 47, and the two second springs 47 are fixed to the inner wall of the active cavity 9 at one end away from the clamping block 46.

[0029] like Figure 4 、 5 As shown, the inner walls of the multiple active cavities 9 are located on the adjacent sides of the two side grooves 11 and are all provided with reset grooves 12 on the top of the main box body 1, and the reset groove 12 is L-shaped. The return mechanism 5 includes an insert 51 that is movably inserted into the fixed groove 42. The side of the insert 51 away from the force block 41 is inclined, and the inclined surface abuts against the end of the rotating plate 44. The end of the insert 51 away from the force block 41 is located in the reset groove 12 and is fixed with a bottom plate 52. The bottom plate 52 is relative to the insert 51. A telescopic rod 53 is fixed to the top of the other end, and a push block 54 is fixed to the end of the telescopic rod 53 away from the bottom plate 52. Semicircular sliders are provided on both sides of the push block 54, and the upper end surface of the push block 54 is flush with the upper end surface of the main box body 1. At the same time, a layer of rubber film is glued around the push block 54 at the opening of the top of the reset groove 12 to ensure sealing. Slide grooves 13 are provided on both sides of the push block 54 at the top of the reset groove 12, and the slide grooves 13 are in contact with the semicircular sliders on both sides of the push block 54.

[0030] It should be noted that a plurality of mounting slots 3 are all provided with fixing mechanisms 4 and return mechanisms 5 of the same structure, and the internal structure dimensions of a single fixing mechanism 4 and return mechanism 5 are adjusted according to the dimensions of the corresponding electronic module 7 .

[0031] The principle and process of the present invention are as follows: when using the present device, a person inserts the electronic module 7 for displaying electronic signals into the installation slot 3. As the electronic module 7 is inserted downward, the bottom of the electronic module 7 abuts against the conical top of the force-bearing block 41, thereby exerting downward pressure on the force-bearing block 41. At the same time, the electronic module 7 is limited by the installation slot 3 and thus connects with the pins of the socket 6. At the same time, when the force-bearing block 41 is pressed downward, the telescopic rod 53 is movable and retracted to receive the downward pressure of the force-bearing block 41, thereby causing the bottom plate 52 to move synchronously to prevent misalignment.

[0032] When the bottom of the electronic module 7 abuts against the bottom of the mounting groove 3, the force-bearing block 41 is pressed downward, thereby applying downward pressure to one end of the two rotating plates 44, causing the two rotating plates 44 to rotate with the rotating rod in the middle of themselves as a fulcrum, thereby converting the downward pressure into a rotational force and transmitting it to the limit block 45. The two limit blocks 45 receive the rotational force, thereby rotating with the rotating rod in the middle of themselves as the center. As the two limit blocks 45 rotate, the abutment against the clamping block 46 is cancelled, so that the two second springs 47 apply a pulling force to the clamping block 46. At the same time, as the two limit blocks 45 continue to rotate, the L-shaped plate surface at the bottom of the limit block 45 applies a thrust to the other side of the bottom of the clamping block 46, causing the clamping block 46 to rotate with the rotating rod in the middle of itself as a fulcrum. The conical surface of the top of the clamping block 46 protrudes from the side groove 11 and is then clamped in the clamping groove 8, forming a clamping fixation for the electronic module 7;

[0033] When the electronic module 7 is fixed, the personnel connects the external power supply equipment, so that the electronic module 7 feeds back electronic signals for teaching demonstration. After the demonstration is completed, the personnel pushes the push block 54, and the push block 54 is pushed and moves along the slide groove 13, thereby driving the telescopic rod 53 to move synchronously, and the telescopic rod 53 drives the bottom plate 52 to move horizontally, thereby pulling the plug block 51 out of the fixed groove 42, and the pulling-out distance is consistent with the groove width of the fixed groove 42, so that the plug block 51 is just pulled out of the groove range of the fixed groove 42 and is located in the opening of the side wall of the force-bearing block 41, which is convenient for subsequent return. As the plug block 51 leaves the groove range of the fixed groove 42, the two rotating plates 44 lose their overall abutment effect with the force-bearing block 41, thereby causing the two second springs 47 to apply thrust to the bottom of the two clamping blocks 46, causing the two clamping blocks 46 to rotate out of the clamping groove 8, so that the electronic module 7 is adjusted to an active state.
