DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 、 Figure 2As shown, a piano cover for a new energy electronic piano that can be flexibly rotated and positioned includes a piano body 1 and a flip cover 2. The left and right sides of the piano body 1 near the rear side and the left and right sides of the flip cover 2 near the front side are fixedly connected to a rotating mechanism 3. The outer side of the rotating mechanism 3 is fixedly connected to a first connecting rod 4, and two first connecting rods 4 are symmetrically distributed on the left and right sides. The lower surface of the flip cover 2 near the front side is rotatably connected to a flap 5, and the inner side of the flap 5 near the left and right sides is fixedly connected to a flip mechanism 6.

[0025] It should be noted that, when the flip cover 2 is buckled onto the outer side of the piano body 1 , the bottom edge of the flip cover 2 is located above the lower rotating mechanism 3 .

[0026] like Figure 2-Figure 4 As shown, the rotating mechanism 3 includes a rotating shaft 31, and the side of the rotating shaft 31 close to the flap 5 is fixedly connected to the left and right sides of the piano body 1 near the rear side and the left and right sides of the flap 2 near the front side. The inner sides of the upper and lower ends of the first connecting rod 4 are fixedly sleeved with a shaft sleeve 32, and the inner side of the shaft sleeve 32 is provided with a plurality of annularly distributed ball grooves 33, and the inner sides of the plurality of ball grooves 33 are movably sleeved with balls 34. The inner side of the rotating shaft 31 is movably sleeved with a fixed sleeve 311, and the outer side of the fixed sleeve 311 is provided with a plurality of annularly distributed fixing grooves 35 away from the flap 5. The outer side of the ball 34 is movably sleeved on the inner side of the fixed groove 35, and the outer side of the fixed sleeve 311 is fixedly connected to a plurality of annularly distributed limiting strips 310 near the flap 5. The inner side of the rotating shaft 31 is provided with a plurality of annularly distributed limiting grooves 39, and the outer side of the limiting strip 310 is movably sleeved on the inner side of the limiting groove 39.

[0027] It should be noted that the limiting groove 39 and the limiting strip 310 are used to limit the fixing sleeve 311 and the rotating shaft 31 from rotating relative to each other. When the ball 34 is located on the inner side of the fixing groove 35 , the shaft sleeve 32 cannot rotate relative to the fixing sleeve 311 .

[0028] like Figure 2-Figure 4 As shown, the inner side of the rotating shaft 31 is threadedly connected to a stud 36, and the end of the stud 36 away from the flap 5 is fixedly connected to a knob 37. The inner side of the fixing sleeve 311 is movably connected to the outer side of the stud 36, and the end of the fixing sleeve 311 away from the flap 5 is rotatably connected to the side of the knob 37 close to the piano body 1. An annular groove 38 is provided on the outer side of the fixing sleeve 311 away from the flap 5, and the annular groove 38 is located on the side of the fixing groove 35 close to the flap 5.

[0029] It should be noted that, by rotating the knob 37, the knob 37 drives the stud 36 to rotate, causing the stud 36 to move left and right. At the same time, the knob 37 drives the fixing sleeve 311 to move left and right. When the ball 34 moves into the inner side of the annular groove 38, relative rotation can occur between the sleeve 32 and the fixing sleeve 311.

[0030] like Figure 3 、 Figure 4 As shown, the difference between the length of the limiting groove 39 and the length of the limiting strip 310 is equal to the inner width of the annular groove 38 .

[0031] It should be noted that the lengths between the limit groove 39, the limit strip 310 and the annular groove 38 are such that when the fixing sleeve 311 moves to the side away from the flap 5 to the maximum distance, the ball 34 is exactly in the inner middle part of the annular groove 38 to limit the movement range of the fixing sleeve 311.

[0032] like Figure 3 As shown, the outer side of the knob 37 is provided with friction lines.

[0033] It should be noted that the friction pattern is used to increase the friction between the hand and the knob 37 , making it easier for the user to rotate the knob 37 .

[0034] like Figure 2 、 Figure 5 As shown, the flip mechanism 6 includes a second connecting rod 61, the rear end of the lower end of the second connecting rod 61 is fixedly connected to the inner side of the flip plate 5 near the left and right sides, the front end of the second connecting rod 61 is rotatably connected to the third connecting rod 62, the upper end of the third connecting rod 62 is slidably connected to the slide groove opened on the left and right sides of the flip cover 2, and the inner side of the upper end of the third connecting rod 62 is threadedly connected to a screw 63.

[0035] It should be noted that when the upper end of the third connecting rod 62 slides in the slide groove, the third connecting rod 62 and the second connecting rod 61 drive the flap 5 to rotate. When the third connecting rod 62 moves to the rearmost side, the flap 5 is just located on the inner side of the flip cover 2. At this time, the flip cover 2 and the flap 5 form a complete piano cover. When the upper end of the third connecting rod 62 moves to the frontmost side, the flap 5 rotates exactly one hundred and eighty degrees. The screw 63 is used to fix the upper end of the third connecting rod 62.

[0036] When the third link 62 is moved to the rearmost side, the flap 5 is just located on the inner side of the flip cover 2. At this time, the flip cover 2 and the flap 5 form a complete piano cover. When the upper end of the third link 62 is moved to the frontmost side, the flap 5 is rotated exactly one hundred and eighty degrees. The screw 63 is used to fix the upper end of the third link 62. The flap 5 is flipped down and fixed by the flip mechanism 6. The flip cover 2 is rotated into a stepped shape by the first link 4, so that the flip cover 2 can be used as a shelf for items such as sheet music. It has more diverse functions, convenient operation, and integrates more functions, avoiding the problem of increased overall volume caused by the dispersion of functional components. Finally, the limiting groove 39 and the limiting strip 310 are used to limit, so that relative rotation cannot occur between the fixing sleeve 311 and the rotating shaft 31. When the ball 34 is located on the inner side of the fixing groove 35, the sleeve 32 When the lever 314 is in the upright position, the lever 316 is in the upright position, and the lever 318 is in the upright position, so that the lever 314 can be rotated relative to the lever 316. When the lever 314 is in the upright position, the lever 316 is in the upright position, and the lever 318 is in the upright position, so that the lever 316 can be rotated relative to the lever 316.
