[0019] 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.

[0020] Embodiment 1:

[0021] See also Figure 1-3 The utility model provides a technical solution: a piano chair for piano teaching, comprising a piano chair board 8, two sets of fixing parts 2, a cushion 9 is arranged on the piano chair board 8, a connecting part 10 is installed at the bottom of the cushion 9, and the bottom of the connecting part 10 passes through the bottom wall of the piano chair board 8, and a latch 11 is slidably connected in the connecting part 10 transversely;

[0022] Both ends of the lower surface of the piano seat board 8 are connected with telescopic parts 3, and the two groups of telescopic parts 3 are slidably connected to the inner cavity of the fixing parts 2, and the bottoms of the two groups of fixing parts 2 are provided with anti-slip bottom plates 1, and fixed seats 4 are installed between adjacent fixing parts 2. Both ends of the inner cavity of the fixing seats 4 are slidably connected with positioning rods 7, and each group of telescopic parts 3 is provided with multiple groups of positioning holes 6 compatible with the positioning rods 7.

[0023] The piano seat board 8 is fixedly connected to the top of the two groups of telescopic parts 3, and the fixing seat 4 is fixedly installed between the adjacent fixing parts 2. The use height of the piano seat board 8 can be adjusted by sliding the telescopic part 3 with the fixing part 2. The use height of the piano seat board 8 can be adjusted, and the use height of the piano chair for teaching with an adjustable steel ball can be suitable for students of different heights. It has a wide range of applications. When adjusting the height of the piano seat board 8, the two groups of positioning rods 7 are not connected to the positioning holes 6 opened in the telescopic part 3. At this time, the position of the telescopic part 3 is not restricted and can slide smoothly in the fixing part 2. After determining the use height of the telescopic part 3, the two groups of positioning rods 7 are connected to the positioning holes 6 opened in the corresponding telescopic part 3, that is, the position of the telescopic part 3 is locked, so as to avoid the piano seat board 8 from sliding down after the use height of the piano chair is determined, thereby improving the use stability of the piano chair; the cushion 9 improves the comfort of the piano chair when in use. By pulling the latch 11 and the connecting part 10, the connecting part 10 can be quickly detached from the piano seat board 8, thereby realizing the rapid replacement of the cushion 9. After the cushion 9 is damaged, it is not necessary to replace the entirety.

[0024] Among them, preferably, the inner wall of the fixed seat 4 is slidably connected with two groups of sliding plates 12, and a compression spring 13 is installed between adjacent sliding plates 12, and the outer sides of the two groups of sliding plates 12 are respectively connected with the two groups of positioning rods 7, and the bottom of the fixed seat 4 is provided with a through slot 14, and the through slot 14 is connected with the inner cavity of the fixed seat 4, and two groups of operating rods 15 are slidably connected in the through slot 14, and the tops of the two groups of operating rods 15 are respectively connected with the bottom walls of the two groups of sliding plates 12;

[0025] The sliding plate 12 is fixedly connected to the operating rod 15, and the sliding plate 12 is fixedly connected to the positioning rod 7. When adjusting the use height of the piano chair, the two groups of operating rods 15 slide in relative directions in the through slots 14. At this time, the adjacent sliding plates 12 are close, the compression springs 13 are compressed, and the two groups of positioning rods 7 are both stored in the inner cavity of the fixed seat 4. At this time, the telescopic member 3 can slide smoothly. When the use height of the piano chair is determined, the positioning rod 7 is aligned with the positioning hole 6 opened in the corresponding telescopic member 3, and the operating rod 15 is released. The compressed compression spring 13 can automatically return to its position, so that the two groups of sliding plates 12 move in opposite directions, and the two groups of positioning rods 7 move in opposite directions and are connected in the corresponding positioning holes 6, that is, the position of the telescopic member 3 is fixed, so as to prevent the piano chair from sliding down after the use height is determined, and the operation is simple and convenient.

[0026] Preferably, a through hole compatible with the connecting piece 10 is opened in the piano seat board 8, and a connecting hole compatible with the pin 11 is opened in the connecting piece 10; the through hole and the connecting hole are both set through, which facilitates the quick disassembly and assembly of the connecting piece 10 and the piano seat board 8, the quick disassembly and assembly of the pin 11 and the connecting piece 10, and the replacement of the cushion 9.

[0027] Preferably, a limiting plate 5 is installed at the bottom of the two groups of telescopic parts 3, and the limiting plate 5 is slidably connected to the inner cavity of the fixing part 2; the limiting plate 5 plays a limiting role to prevent the telescopic part 3 from escaping from the inner cavity of the fixing part 2.

[0028] Preferably, pull rings are installed at the bottom of the two sets of operating rods 15, and the hand-held ends of the pull rings are covered with anti-skid rubber sleeves; the pull rings facilitate pulling the operating rods 15, and the anti-skid rubber sleeves play an anti-skid role to prevent the hands from slipping when holding the pull rings.

[0029] Embodiment 2:

[0030] Reference Figure 1 This embodiment is different from the first embodiment in that: the lower surfaces of the two sets of anti-skid bottom plates 1 are embedded with corrugated protrusions; the protrusions increase the friction between the anti-skid bottom plates 1 and the working ground, further improving the stability of the entire piano chair when in use.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
