DETAILED DESCRIPTION

[0023] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0024] See also Figure 1 , Figure 2 , Figure 3 The utility model is a portable electro-acoustic musical instrument practice machine, comprising a box body 1, which serves as a protective storage mechanism of the vocal practice machine. The inner wall of the box body 1 is rotatably connected to a connecting rod 2, and the outer surface of the connecting rod 2 is fixedly connected to a rack 3. A plurality of racks 3 are provided and are evenly distributed on the connecting rod 2. The rotation of the connecting rod 2 will drive the rack 3 to rotate around the central axis of the connecting rod 2.

[0025] like Figure 2 , Figure 3 , Figure 5 As shown, the inner wall of the box body 1 is slidably connected with a storage box 5 and a practice box 6. The storage box 5 can store the earphones and the connecting wires to prevent the earphones and the connecting wires from being placed randomly and lost. The storage box 5 is fixedly connected with a first tooth plate 7 on the side close to the connecting rod 2, and the practice box 6 is fixedly connected with a second tooth plate 8 on the side close to the connecting rod 2. Specifically, the first tooth plate 7 and the second tooth plate 8 are the same, and the sides close to each other are both provided with teeth. The outer surfaces of the first tooth plate 7 and the second tooth plate 8 are both slidably connected with the box body 1.

[0026] Replay Figure 5The outer surfaces of the first tooth plate 7 and the second tooth plate 8 are both meshed with the rack 3. In this embodiment, the first tooth plate 7 and the second tooth plate 8 are meshed with the rack 3 so that when the storage box 5 is pulled, the storage box 5 will drive the first tooth plate 7 to slide horizontally along the box body 1. At this time, the first tooth plate 7 will engage with the rack 3 to cause the connecting rod 2 to start rotating. At this time, the connecting rod 2 will drive the second tooth plate 8 through the rack 3 to move it in the opposite direction of the first tooth plate 7, so that the practice box 6 can be pushed by the second tooth plate 8 to move horizontally along the box body 1, and then the storage box 5 and the practice box 6 are pulled out at the same time.

[0027] like Figure 2 , Figure 4 , Figure 5 As shown, T-slots 9 are provided inside the storage box 5 and the practice box 6, and the inner wall of each T-slot 9 is slidably connected to the corresponding first tooth plate 7 and second tooth plate 8. Specifically, the opening direction of the T-slot 9 is horizontal to the first tooth plate 7 and the second tooth plate 8. When the storage box 5 is pulled, the first tooth plate 7 will slide in the T-slot 9 on the practice box 6, and the second tooth plate 8 will slide in the T-slot 9 on the storage box 5, thereby increasing the integrity between the storage box 5 and the practice box 6.

[0028] In this embodiment, the ends of the storage box 5 and the practice box 6 that are close to each other are fixedly connected with push rods 10, and the push rods 10 are located below the storage box 5 and the practice box 6. The ends of the two push rods 10 that are close to each other are inserted with fixing rings 11. The fixing rings 11 are provided with slots at the ends close to the corresponding push rods 10. The size of the slots is the same as that of the push rods 10. Each fixing ring 11 is fixedly connected with a spring 12 at one end close to the connecting rod 2. Specifically, when the storage box 5 and the practice box 6 enter the box body 1, the push rod 10 will be inserted into the slot on the corresponding fixing ring 11, and then continue to push the storage box 5 and the practice box 6, and the spring 12 will be compressed at this time.

[0029] See also Figure 3 , Figure 5 One end of each spring 12 close to the connecting rod 2 is fixedly connected to the box body 1, and one end of each spring 12 away from the connecting rod 2 is fixedly connected to the corresponding fixing ring 11. Specifically, when no external force acts on the storage box 5 and the practice box 6, the spring 12 will push the corresponding storage box 5 or the practice box 6 under the action of its rebound force, so that it is pushed out of the box body 1, and then it is convenient to pull the storage box 5 and the practice box 6 to slide out of the box body 1.

[0030] Replay Figure 2 A box cover 13 is hinged on both sides of the box body 1, and an elastic plate 14 is fixedly connected to the upper surface of each box cover 13. Specifically, the box cover 13 serves as a closing mechanism of the box body 1. When the two box covers 13 are closed, the elastic force of the spring 12 can prevent the storage box 5 or the practice box 6 from sliding out and causing damage.

[0031] like Figure 2 , Figure 3 As shown, two triangular clamping plates 15 are fixedly connected to the upper surface of the box body 1, and the slope of each triangular clamping plate 15 faces the corresponding box cover 13. Each triangular clamping plate 15 is clamped with the corresponding elastic plate 14. Specifically, when the box cover 13 is closed, the elastic plate 14 will contact the corresponding triangular clamping plate 15. When the box cover 13 is continuously closed, the elastic plate 14 will be clamped with the corresponding triangular clamping plate 15. At this time, a "snap" sound will be heard, and the elastic plate 14 will reset itself and contact the box body 1.

[0032] like Figure 1 As shown, an elastic band 16 is provided below the box body 1, and both ends of the elastic band 16 are fixedly connected to the box body 1. Specifically, the elastic band 16 is elastic and can be tied around the user's arm, so that the device can be easily carried.

[0033] See also Figure 4 A display screen 4 and a sound generator 19 are fixedly mounted on the upper surface of the practice box 6. An earphone slot 18 and a connecting slot 17 are provided on the upper surface of the practice box 6.
