[0035] In the specific embodiment of the present invention, the working principle and internal structure of the digital electronic piano 1 are common knowledge to those skilled in the art, and thus will not be described in detail. The installation groove 10 is configured to rotate the connecting shaft 12 .

[0036] Specifically, the protective mechanism is arranged on the digital electronic piano 1, and the protective mechanism includes a cover plate 2, a slide groove 7 and a limit slide bar 9. There are two slide grooves 7, both of which are opened on the digital electronic piano 1, and the two slide grooves 7 are symmetrically arranged. The limit slide bar 9 is slidably connected between the two slide grooves 7, and the cover plate 2 is fixedly connected to the circumferential surface of the limit slide bar 9.

[0037] In a specific embodiment of the utility model, the slide groove 7 is configured to be slidably connected to the limit slide bar 9, which is slidably connected between the two slide grooves 7 so that the limit slide bar 9 can slide in the two slide grooves 7. The cover plate 2 is fixedly connected to the limit slide bar 9 so that the cover plate 2 can be moved by the limit slide bar 9, and the cover plate 2 can be rotated through the limit slide bar 9. The limit slide bar 9 is moved to one end of the slide groove 7 so that the cover plate 2 can be rotated, and the cover plate 2 is rotated into the rotating groove 8.

[0038] Specifically, the rotating parts are arranged on the digital electronic piano 1, and each group of rotating parts includes a rotating shaft 12 and a socket 13. The rotating shaft 12 is rotatably connected between the side walls of the mounting groove 10, and a plurality of sockets 13 are provided. The plurality of sockets 13 are all opened on the circumferential surface of the rotating shaft 12, and the plurality of sockets 13 are symmetrically arranged.

[0039] In a specific embodiment of the utility model, the rotating shaft 12 is rotatably connected between the side walls of the mounting groove 10, so that the rotating shaft 12 can be rotated. The setting of the socket 13 is used to movably insert the plug rod 15. The plug rod 15 is movably inserted into the socket 13, so that the plug rod 15 can limit the rotation of the rotating shaft 12. The rotation of the rotating shaft 12 can drive the connecting tube 3 to rotate, so that the connecting tube 3 can be retracted into the mounting groove 10.

[0040] Specifically, the plug-in limit component is arranged on the digital electronic piano 1, and the plug-in limit component is connected to the rotating component. The plug-in limit component includes a pull rod 6, a vertical plate 11, a limit plate 14, an insertion rod 15 and a spring 16. Two vertical plates 11 are provided, and the two vertical plates 11 are fixedly connected between the side walls of the mounting groove 10. Two insertion rods 15 are provided, and the two insertion rods 15 are movably plugged into the two vertical plates 11, and the same side ends of the two insertion rods 15 are respectively movably plugged into two of the insertion holes 13. Two limit plates 14 are provided, and the limit plates 14 are fixedly connected to the circumferential surface of the insertion rod 15. Two springs 16 are provided, and the two springs 16 are fixedly connected between the limit plate 14 and the vertical plate 11, and the two springs 16 are respectively sleeved on the two insertion rods 15. The pull rod 6 is fixedly connected to the same side end of the two insertion rods 15.

[0041] In a specific embodiment of the utility model, the two vertical plates 11 are used to connect the insertion rod 15. By movably inserting the insertion rod 15 into the insertion hole 13, the rotation of the rotating shaft 12 can be limited. The movement of the insertion rod 15 can be limited by the setting of the limit plate 14 and the spring 16. By fixing the insertion rod 15 and the limit plate 14, the movement of the insertion rod 15 can drive the movement of the limit plate 14, and the movement of the limit plate 14 can compress the spring 16.

[0042] Specifically, two groups of support mechanisms are provided, each group of support mechanisms is arranged on each group of adjustment mechanisms, and each group of support mechanisms includes a connecting tube 3, an L-shaped support foot 4 and a fixing screw 5. The connecting tube 3 is fixedly connected to the circumferential surface of the rotating shaft 12, one end of the L-shaped support foot 4 is movably inserted in the connecting tube 3, the fixing screw 5 is threadedly connected to the side end of the connecting tube 3, and one end of the fixing screw 5 is movably inserted on the L-shaped support foot 4.

[0043] In a specific embodiment of the utility model, the connection tube 3 is used to connect the L-shaped supporting foot 4, and the cover plate 2 and the connection tube 3 are used to support the digital electronic piano 1. The height of the digital electronic piano 1 can be adjusted by adjusting the length of the L-shaped supporting foot 4 inserted into the connection tube 3, so that the digital electronic piano 1 is suitable for use by people of different heights. The L-shaped supporting foot 4 can be fixed to the connection tube 3 by the setting of the fixing screw 5, thereby fixing the adjusted length of the connection tube 3 and the L-shaped supporting foot 4.

[0044] Specifically, a rotation groove 8 is provided at a side end of the digital electronic piano 1 .

[0045] In a specific embodiment of the present invention, the rotation groove 8 is provided for placing the cover plate 2 .

[0046] The working principle or working process of the digital electronic piano that is easy to disassemble and assemble provided by the utility model is as follows: the cover plate 2 is pushed to move, and the movement of the cover plate 2 drives the limit slide bar 9 to move, so that the limit slide bar 9 slides in the slide groove 7. When the limit slide bar 9 moves to one end of the slide groove 7, the cover plate 2 can be rotated by the limit slide bar 9, so that the cover plate 2 is rotated into the rotating groove 8, and the pull rod 6 is pulled. The movement of the pull rod 6 drives the insertion rod 15 to move, and the movement of the insertion rod 15 drives the limit plate 14 to move. The limit plate 14 moves the compression spring 16. After the insertion rod 15 is moved out of the insertion hole 13, the rotating shaft 12 can be rotated. The rotation of the rotating shaft 12 drives the connecting tube 3 to rotate, thereby adjusting the position of the connecting tube 3, and rotating the fixing screw 5 so that the L-shaped supporting foot 4 can move in the connecting tube 3. The L-shaped supporting foot 4 slides in the connecting tube 3, thereby adjusting the distance between the digital electronic piano 1 and the L-shaped supporting foot 4, and tightening the fixing screw 5 to fix the position of the L-shaped supporting foot 4.
