Piano pedal auxiliary device with adjustable height

Abstract

The invention discloses a piano pedal auxiliary device with an adjustable height and relates to the field of piano auxiliary mechanisms. The piano pedal auxiliary device comprises a vertical piano body and an installation fixing box. The surface of the installation fixing box is sleeved with a lifting sleeve box and a pedal mounting box; a linear bearing is installed on the top face of the pedal mounting box and sleeved with a transmission clamping strip, a transmission ball sleeve, a ball head connecting piece, a transmission ball rod and an abutting transmission block are installed at the bottom end of the transmission clamping strip; a hoisting support and an elastic telescopic rod are installed on the top face of an inner cavity of the pedal mounting box; and a lead screw lifting mechanism is installed on the inner side of the installation fixing box and the lifting sleeve box. According to the invention, the same external auxiliary pedal structure is arranged in the lifting sleevebox; by treading the peripheral auxiliary pedal, the force of treading the peripheral auxiliary pedal by a human body is transmitted to the original piano pedal by utilizing the transmission clampingstrip and the transmission ball rod; and compared with the traditional electric structure, the mechanical transmission structure has no delay, so that the control in the music creation process is smoother, and the creation experience of a user is improved.
