DETAILED DESCRIPTION
[0020] 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.
[0021] See also Figure 1-Figure 3 The utility model provides a technical solution: a music score display board with convenient display angle adjustment, comprising a base 1, a connecting block 11 and a connecting shaft 2,
[0022] A connecting block 11 is welded to the inner side of the base 1, and a connecting shaft 2 is welded to the inner side of the base 1 near the connecting block 11. The connecting shaft 2 is rotatably connected to the bottom of the support plate 21. A groove 3 is provided in the middle of one side of the support plate 21, and slide grooves 31 are provided on both sides of the groove 3. The slide groove 31 is movably connected to a connecting slider 32. The connecting slider 32 is rotatably connected to the top of an electric telescopic rod 33. The bottom of the electric telescopic rod 33 is rotatably connected to a mounting shaft 34. Both ends of the mounting shaft 34 are welded to a side of the inner side of the base 1 away from the connecting block 11. Multiple groups of limiting grooves 4 are provided on both sides and the top of the support plate 21. The limiting grooves 4 are slidably connected to a limiting slider 41, and the top of the limiting slider 41 is welded to an extension plate 42.
[0023] In specific implementation, before using the electric telescopic rod 33, after putting the music score into the limit frame 6, start the electric telescopic rod 33, and the electric telescopic rod 33 drives the support plate 21 to adjust the angle. When the electric telescopic rod 33 is extended, the top of the electric telescopic rod 33 slides in the slide groove 31 on the rear side of the support plate 21, and the support plate 21 tilts downward. When the electric telescopic rod 33 is retracted, the support plate 21 tilts backward, the adjustment angle is wider, the use is more convenient, and the supporting effect is better. When the use is finished, the electric telescopic rod 33 is completely retracted, and the support plate 21 can be flipped backward until the electric telescopic rod 33 is plugged into the groove 3 on the rear side of the support plate 21, which saves more space. The music score display board with convenient display angle adjustment is convenient for display and use. The electric telescopic rod 33 is used for angle adjustment, and the range of angle adjustment is wider and more convenient.
[0024] See also Figure 1-Figure 2 It can be seen that a connecting frame 5 is arranged between the two extension plates 42, one side of the connecting frame 5 is welded to the rear side of the support plate 21, a connecting spring 51 is installed in the connecting frame 5, both ends of the connecting spring 51 are connected to one end of two groups of connecting rods 52, the other end of the connecting rod 52 is welded to the extension plate 42, a limiting frame 6 is welded to the side of the support plate 21 away from the connecting frame 5, the inner side of the limiting frame 6 is connected to one end of the limiting spring 61, the other end of the limiting spring 61 is connected to one side of the extrusion plate 62, the other side of the extrusion plate 62 is connected to the first rubber layer 63, a mounting frame 7 is welded to one side of the bottom of the base 1, the mounting frame 7 is threadedly connected to the screw 71, an extrusion block 72 is installed on the top of the screw 71, and the upper side of the extrusion block 72 is connected to the second rubber layer 73.
[0025] In specific implementation, before using the support plate 21, the installation frame 7 is plugged into the desktop to be placed. After the plugging, the screw 71 is screwed inward until the second rubber layer 73 is pressed against the lower side of the desktop. The second rubber layer 73 will increase the friction with the bottom of the desktop, and the limiting effect is better. After the installation frame 7 is clamped with the desktop, the display board is no longer restricted in the placement height. If the height is large, the electric telescopic rod 33 can be started to extend and the support plate 21 can be pressed down. After the music score is plugged into the limit frame 6, the limit spring 61 in the limit frame 6 will be squeezed forward until the first rubber layer 63 at the top of the squeezing plate 62 is squeezed with the music score. The paper pages of the music score will not loosen and fall off from the limit frame 6. The music score display board with convenient display angle adjustment has a better clamping effect.
[0026] In summary, before using the music display board with convenient display angle adjustment, first plug the installation frame 7 into the desktop, then use the screw 71 to push the second rubber layer 73 against the lower side of the desktop, put the music score into the limit frame 6 for limiting, start the electric telescopic rod 33, and the electric telescopic rod 33 drives the support plate 21 to adjust the angle until it stops after adjusting to a suitable angle.
