[0027] like Figure 3-4As shown, the utility model provides a technical solution of a piano cover buffer structure: the buffer mechanism 7 includes a sleeve 71, a support rod 72 and two positioning plates 73. The interior of the sleeve 71 is sleeved with the exterior of the support rod 72. A left-right through-hole 1 710 is provided on the side of the sleeve 71 close to the L-shaped fixed plate 5. A connecting hole 711 is provided in the middle of one end of the sleeve 71 close to the L-shaped fixed plate 5. A left-right through-hole 2 720 is provided on the side of the support rod 72 close to the sliding iron block 6. A mounting rod 74 is inserted in the middle of the two positioning plates 73. The left and right sides of the mounting rod 74 are respectively provided with threads 740. The left and right sides of the mounting rod 74 are respectively threadedly connected with threaded sleeves 75. 4 and the threaded sleeve 75 are used to install the sleeve 71 and the support rod 72. The bottoms of the two positioning plates 73 are fixedly connected to the top of the transverse surface of the L-shaped fixed plate 5. The outer wall of the mounting rod 74 is plugged into the inner wall of the socket 710. The sliding iron block 6 is mirror-set with the same structure as the positioning plate 73, the mounting rod 74 and the threaded sleeve 75. The outer wall of the end of the support rod 72 away from the sliding iron block 6 is fixedly connected to a rubber sleeve 76. The outer wall of the rubber sleeve 76 overlaps the inner wall of the sleeve 71. The middle part of the end of the rubber sleeve 76 away from the support rod 72 is fixedly connected to a rubber plug 77. When the support rod 72 is extended and retracted along the inner wall of the sleeve 71, the rubber sleeve 76 increases the friction between the support rod 72 and the inner wall of the sleeve 71.

[0028] like Figure 5 As shown, the utility model provides a technical solution for the piano cover closing buffer structure: the left and right sides of the inner wall of the movable groove 4 are respectively provided with sliding grooves 401, the left and right ends of the sliding iron block 6 are respectively fixedly connected with slide plates 61, the outer wall of the slide plate 61 is slidably connected to the inner wall of the sliding groove 401, the slide plate 61 slides along the inner wall of the sliding groove 401, so as to improve the stability of the movement of the sliding iron block 6, the positioning assembly 8 comprises a plurality of springs 81 and a magnet plate 82, the top of the inner wall of the movable groove 4 is equidistantly arrayed with the same number of mounting grooves 402 as the springs 81, the tops of the plurality of springs 81 are respectively fixedly connected to the inner walls of the plurality of mounting grooves 402, and the bottoms of the plurality of springs 81 are all fixedly connected to the tops of the magnet plates 82, when the piano cover is closed, the sliding iron block 6 moves to the magnet plate 82 and is magnetically fitted with the magnet plate 82, so as to automatically adjust the position of the device body fitting the piano.

[0029] The working principle of this piano cover buffer structure is described in detail below.

[0030] like Figure 1-5As shown, when in use, first, the second connecting plate 2 is rotated out of the connecting groove 3 in the first connecting plate 1 through the connecting sleeve rod 9, so that the support rod 72 extends along the inner wall of the sleeve 71, and the socket 1 710 in the sleeve 71 and the socket 2 720 in the support rod 72 are respectively rotated along the outer wall of the mounting rod 74, so that the device is turned outward to open, and then the buffer device is respectively attached to the surface of the piano body and the piano cover by the double-sided tape 10. When the piano cover is closed, the second connecting plate 2 is turned inward, so that the support rod 72 is retracted along the inside of the sleeve 71. The rubber sleeve 76 shrinks and slides downward along the inner wall of the sleeve 71, discharging the gas in the sleeve 71 through the connecting hole 711. At the same time, the slide plates 61 on both sides of the slide block 6 slide along the inner walls of the slide groove 401 respectively. When the slide plate 61 slides to the magnet plate 82, the magnet plate 82 is magnetically attached to the surface of the slide block 6 and squeezes the spring 81 into the installation groove 402, which plays a certain buffering role and can automatically adjust the position of the device body and the piano, so that the rubber plug 77 is inserted into the inside of the connecting hole 711, thereby closing the second connecting plate 2 inside the connecting groove 3.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
