Piano pedal auxiliary device capable of adjusting height

Abstract

The invention discloses a piano pedal auxiliary device capable of adjusting the height. The piano pedal auxiliary device comprises a base, a support, a pressing device and a vertical lifting device. The pressing device comprises an auxiliary pedal, a rapping hammer and a power transmission mechanism. The power transmission mechanism is used for transmitting the pressure borne by the auxiliary pedal to the rapping hammer and pushing the rapping hammer to vertically move so as to press the piano pedal. The pressing device further comprises a linkage mechanism. The linkage mechanism comprises a first lead screw transmission mechanism. The first lead screw transmission mechanism comprises a first lead screw and a first lead screw nut. The upper end of the first lead screw is installed on a third transmission block, and the lower end of the first lead screw vertically extends downwards. The position, making contact with the first lead screw, of the rapping hammer is provided with a recedinghole. The linkage mechanism further comprises a synchronous driving mechanism which is used for driving the first lead screw nut to rotate so that the first lead screw and the support can synchronously rise and fall. The piano pedal auxiliary device can adjust the height of a pedal so that the pedal can adapt to children at different heights.

Description

technical field [0001] The invention relates to a piano, in particular to a height-adjustable piano pedal auxiliary device.
