[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a digital circuit experiment box, including a box body 1, a box cover 2, a circuit board 3, a buckle 4, a card block 5, a handle 6, a partition bar 7, a wire storage box 8, a spring 9, a drawer 10, a clamping ring 11, a pressure plate 12, and a groove 13.

[0031] This device has the effect of being easy to repair and replace, specifically:

[0032] A box cover 2 is arranged on the upper surface of the box body 1, and the box body 1 and the box cover 2 are rotatably connected. A circuit board 3 is installed inside the box body 1, and a buckle 4 is rotatably arranged on the surface of the box cover 2. A card block 5 is correspondingly arranged on the surface of the box body 1. The circuit board 3 is a split structure, and the split structure is convenient for local maintenance and replacement of a certain circuit. The split structure includes a partition bar 7, and the partition bar 7 divides the surface of the circuit board 3 into various small modules, and the various modules of the circuit board 3 are electrically connected to each other to form a whole;

[0033] like Figure 2 and Figure 5 As shown, digital circuit experiments can be carried out using the circuit board 3 in the box 1. When the circuit board 3 is damaged during the experiment, the dividing strip 7 divides the circuit board 3 into independent modules. Therefore, if a part of the circuit board 3 is damaged, there is no need to replace the entire circuit board 3. The damaged module of the circuit board 3 can be repaired and replaced before continuing to use.

[0034] This device has the effect of storing wires, specifically:

[0035] A wire placement structure is provided inside the box 1. The wire placement structure utilizes a moving wire storage box 8 to store the wires. The wire placement structure includes a wire storage box 8. The wire storage box 8 is an open structure, and the wire storage box 8 is slidably connected to the inner wall of the box 1. A spring 9 is provided on the lower surface of the wire storage box 8, and the other end of the spring 9 is fixed to the bottom surface of the box 1. A drawer 10 is slidably provided on the inner wall of the wire storage box 8, and the drawer 10 passes through the side surface of the wire storage box 8. A handle 6 is provided on one side of the drawer 10, and a spring 9 is provided on the other side of the drawer 10. The other end of the spring 9 is fixed to the inner wall of the drawer 10. A plurality of snap rings 11 are provided on the surface of the drawer 10. Two drawers 10 are provided in parallel up and down inside the drawer 10, and the structures of the two drawers 10 are exactly the same.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the box cover 2 is closed with the box body 1, the wire storage box 8 is stored inside the box body 1. At this time, the spring 9 on the lower surface of the wire storage box 8 is in a compressed state. At the same time, the spring 9 on the side of the drawer 10 is also in a compressed state. The buckle 4 is separated from the card block 5, and the box cover 2 is rotated to open the box cover 2 on the surface of the box body 1. After the pressure of the box cover 2 is lost, the wire storage box 8 is bounced up by the spring 9, which is convenient for taking the wires. The wire storage box 8 is pulled upward by hand, and the wire storage box 8 drives the drawer 10 to move upward. When the drawer 10 moves upward and is aligned with the box 1, After the side wall is separated, the drawer 10 loses the pressure of the box body 1 and pops up to the right under the action of the spring 9, exposing the surface of the drawer 10. At this time, the wire can be taken out from the surface of the clamping ring 11 in the drawer 10 to conduct the experiment. After the experiment is completed, the clamping ring 11 in the drawer 10 is used to clamp and store the wire. The drawer 10 is held and pushed toward the inside of the wire storage box 8. The drawer 10 compresses the spring 9 inward. When the drawer 10 completely enters the wire storage box 8, the wire storage box 8 is pressed downward. At this time, the box cover 2 is rotated and engaged with the box body 1 to complete the storage of the wire storage box 8.

[0037] This device has the effect of clamping materials, specifically:

[0038] The surface of the box cover 2 is provided with a clamping structure, which can fix the text materials during the experiment by rotating the pressing plate 12, so as to facilitate the experiment. The clamping structure includes a pressing plate 12, which is rotatably connected to the inner surface of the box cover 2. The inner surface of the box cover 2 is provided with a groove 13, and the pressing plate 12 is accommodated in the groove 13. Semicircular taking openings are provided on both sides of the groove 13. The pressing plate 12 and the box cover 2 form a telescopic structure;

[0039] like Figure 2 and Figure 6 As shown, when the box cover 2 is opened for the experiment, the semicircular taking openings on both sides of the groove 13 are used to pull the pressing plate 12 out of the groove 13 and rotate it, and the pressing plate 12 is used to press the text data on the inner surface of the box cover 2, which can facilitate the viewing of the text data during the experiment. After the experiment is completed, the pressing plate 12 is rotated to store the pressing plate 12 in the groove 13, which can prevent the pressing plate 12 from pressing the circuit board 3 when the box cover 2 is closed, thereby preventing the circuit board 3 from being damaged.

[0040] Working principle: When using the digital circuit experiment box, the dividing strip 7 divides the circuit board 3 into multiple modules. Each module is independently arranged and electrically connected. When a part of the circuit board 3 is damaged, only the damaged module needs to be repaired and replaced before it can be used again. A wire storage box 8 is slidingly arranged in the box body 1. When the box cover 2 is closed, the wire storage box 8 is compressed in the box body 1. When the box cover 2 is opened, the wire storage box 8 bounces up under the action of the spring 9 on the lower surface, which is convenient for taking and placing the wires. A sliding drawer 10 is arranged in the wire storage box 8 to store and organize the wires to prevent the wires from being entangled and knotted. A groove 13 is arranged on the surface of the box cover 2. The retractable pressing plate 12 is accommodated in the groove 13. The pressing plate 12 is rotatably connected to the box cover 2. The pressing plate 12 can be used to temporarily fix text materials on the inner surface of the box cover 2, which is convenient for checking materials during the experiment and increases the overall practicality.
