DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1-8The utility model provides a technical solution: a portable music stand for music teaching, comprising: a box 1, legs 2, handles 3, receiving columns 4, mounting holes 5, studs 6, extension columns 7, fixed legs 8, receiving plates 9, baffles 10, music boards 11, pressing sheets 12, bulbs 13, shading plates 14, switches 15, threaded rods 16, slides 17, connecting rods 18, box covers 19 and sponge pads 20;

[0032] When using the portable music stand for music teaching, Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, first unscrew all the legs 2 at the bottom of the box 1, then unzip the box 1 and the box cover 19, then remove the box cover 19 from the top of the box 1, take out the receiving plate 9 and the receiving column 4 from the top of the box 1, prop up the fixed legs 8 on both sides of the receiving column 4, rotate the receiving column 4, and screw it into the screw hole in the middle of the upper side of the box 1. After the fixed legs 8 are aligned with the screw holes on the upper side of the box 1, screw the screws into the screw holes in the fixed legs 8, and then the receiving column 4 can be firmly fixed to the upper side of the box 1, and then the receiving plate 9 is screwed onto the extension column 7 on the upper side of the receiving column 4. At this time, the music stand is roughly assembled. If the ground is uneven or the height of the legs 2 is different, the music stand will shake, then the legs 2 can be rotated and adjusted as needed until the music stand does not shake.

[0033] like Figure 2 As shown, unscrew the stud 6 from the front side of the receiving column 4, hold the extension column 7 and lift it up. After adjusting to a suitable height, screw the stud 6 into the screw hole in the extension column 7 through the mounting hole 5 on the front side of the receiving column 4, and the height adjustment is completed;

[0034] like Figure 3 and Figure 4 As shown, when it is just taken out, the receiving plate 9 is in a parallel state with the music board 11 and the connecting rod 18, and the slide 17 is located at the inner rear side of the receiving plate 9. The threaded rod 16 of the receiving plate 9 is rotated. Since the threaded rod 16 is rotatably connected with the receiving plate 9, the threaded rod 16 is threadedly connected with the slide 17. The rotation of the threaded rod 16 will bring the slide 17 forward, and the slide 17 is rotatably connected with the connecting rod 18, and the connecting rod 18 is rotatably connected with the music board 11. When the slide 17 moves forward, it will lift the music board 11, so that the angle between the receiving plate 9 and the music board 11 can be adjusted. When it is adjusted to a suitable angle, the threaded rod 16 can be loosened.

[0035] like Figure 2 and Figure 4As shown, when the sheet music board 11 is raised, the pressing plate 12 above the sheet music board 11 is turned to the side, and the sheet music is placed on the sheet music board 11. At this time, the lower side of the sheet music will hit the baffle 10, and the baffle 10 can prevent the sheet music from sliding off. Then the pressing plate 12 is lifted and pressed onto the sheet music. The pressing plate 12 is made of a hard elastic material and can clamp the sheet music to prevent the sheet music from turning pages due to wind. In addition, a soft pad is provided on the upper side of the pressing plate 12 to protect the sheet music from being crushed by the pressing plate 12. If the light in the classroom is dim, turn on the switch 15 on the portable music stand for music teaching, and the light bulb 13 will light up and shine on the sheet music on the sheet music board 11. In addition, a shading plate 14 fixedly connected to the sheet music board 11 is provided on the upper side of the light bulb 13 to prevent the light from shining on the eyes of the students listening to the lecture, and also reduce the light from shining on the eyes of the teacher, so as to protect the eyes of the teacher and the students.

[0036] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, after the teaching is completed, the music stand needs to be folded up. First, the music board 11 is dropped by rotating the threaded rod 16 until the music board 11 is parallel to the receiving plate 9, and the connecting rod 18 is between the receiving plate 9 and the music board 11, which does not affect the folding process. Then, the receiving plate 9 is rotated to remove it, and then the screws above the fixed legs 8 are unscrewed, the receiving column 4 is rotated to remove it, and the stud 6 is removed, and the extension column 7 is received in the receiving column 4, and the zipper between the box 1 and the box cover 19 is pulled up. The sponge pad 20 on the inside of the box cover 19 can clamp the equipment between the box 1 and the box cover 19 to prevent the receiving column 4 and the music board 11 from shaking when the box 1 is erected, which will damage the equipment for a long time. Then all the legs 2 on the lower side of the box 1 are screwed into the box 1, and the handle 3 can be lifted to carry the music stand away, which is very convenient to carry.
