Technical Field

The invention relates to the field of pianos, in particular to an adjustable piano.

Background

A piano is a keyboard instrument among western classical music, and is classified into a grand piano and an upright piano. Because grand piano is relatively space-consuming, people want to use grand piano upright. This led to the appearance of early upright pianos. Therefore, grand pianos are much earlier than upright pianos. The vertical piano adopts a design scheme that the strings are staggered, so that the height and the thickness are effectively saved. Nowadays, the performance of the piano is becoming more and more popular, especially for players or singers, playing while playing is already an indispensable content for stage performance, however, when players play the piano, the duration of time moves back and forth or lean towards the body due to the need of playing keys at two ends, and long-time playing can generate great load on the waist and the lumbar.

Disclosure of Invention

The invention provides an adjustable piano, which enables a seat to move horizontally smoothly, and players do not need to twist waist to play, so that waist muscles or vertebrae are not damaged.

The technical purpose of the invention is realized by the following technical scheme: the utility model provides an adjustable piano, includes piano body and seat, wherein, the piano body includes the musical instrument foot, both sides the musical instrument foot passes through the seat slide linkage, the seat can horizontal slip on the seat slide.

Preferably, the seat slide rail is a cylindrical straight rod, the seat comprises a horizontal chute and an auxiliary chute, the horizontal chute is an arc straight chute which is formed by horizontally extending upwards sunken lower surface of the seat, the auxiliary chute is a rectangular straight chute which is formed by upwards sunken side of the lower surface of the seat far away from the horizontal chute, and a roller is arranged in the auxiliary chute.

Preferably, the seat has an instep surface and a leg rest surface, the instep surface is a plane horizontally extending from an inner vertical surface of the seat to an outer side, and the leg rest surface is an inclined plane extending obliquely upward from a tip end of the instep surface to an upper surface of the seat.

Preferably, the seat is further provided with a slide control part for controlling the seat to move on the seat slide rail in a fast and slow manner.

Preferably, the slip control part comprises a tread vertical groove, a pedal transverse groove, a vertical blocking rod and a transverse elastic plate, the tread vertical groove is a vertical groove which vertically penetrates downwards from the pedal face to the transverse sliding groove, the pedal transverse groove is a horizontal vertical groove which reversely extends from two side wall faces of the tread vertical groove, the vertical blocking rod is a straight rod which is positioned in the tread vertical groove, the transverse elastic plate is a flat plate which horizontally and reversely extends from two sides of the vertical blocking rod to two sides of the pedal transverse groove, and the transverse elastic plate is connected to the lower surface of the pedal transverse groove through a spring.

Preferably, a lock stop portion for locking the seat slide is further provided.

Preferably, the locking part comprises a transverse cavity, a lock seat rod and rail surface grooves, the transverse cavity is a horizontal cavity which penetrates from the inner vertical surface of the seat to the transverse sliding groove, the lock seat rod is a straight rod arranged in the transverse cavity, the rail surface grooves are grooves which are recessed inwards from the surface of the seat sliding rail, and the rail surface grooves are distributed at intervals in the horizontal direction.

Preferably, the transverse through cavity comprises a middle thin cavity and an end wide cavity, the end wide cavity is located at two ends of the middle thin cavity, the vertical cross-sectional area of the middle thin cavity is smaller than that of the end wide cavity, the lock seat rod comprises a middle thin rod and an end wide rod, the middle thin rod is located in the middle thin cavity, the end wide rods are located in the end wide cavities at two sides, and the vertical cross-sectional area of the end wide rods is larger than that of the middle thin rod.

Preferably, the end wide rod is further provided with an easy-to-slide surface, and the easy-to-slide surface is a circular table surface obliquely extending from the vertical surface of the end wide rod to the cylindrical wall surface.

In conclusion, the invention has the following beneficial effects: the chair can move smoothly, and players do not need to twist waist to play, so that waist muscles or vertebrae are prevented from being damaged.
