Abstract

The invention relates to an improvement of a musical instrument bass mechanism, in particular to a bass transmission mechanism of an accordion bass machine. A consonance thread rolling groove and a bass thread rolling groove of the invention are made of hard aluminum alloy materials and are made by means of disposable hot extrusion forming; an apical plate and a pushing tooth are made of stainless materials, the whole apical plate is welded with the pushing tooth, and the shape of the pushing tooth welded with the apical plate is a cylinder; the frame assembly of the accordion bass machine adopts an actively connecting method. The consonance thread rolling groove and the bass thread rolling groove of the invention are made of the hard aluminum alloy materials and are made by means of disposable hot extrusion forming, which not only improves the precision of a gadget but also prolongs the service life thereof; the apical plate and the pushing tooth are made of the stainless materials, the whole apical plate is welded with the pushing tooth, and the shape of the pushing tooth welded with the apical plate is the cylinder, which causes the pushing tooth on the apical plate and the thread rolling groove to be connected with a transferring moment so as to carry out rolling friction, thus reducing moving resistance and improving transmission sensitivity; the frame assembly of the accordion bass machine adopts the actively connecting method, thus being convenient for segmental assembly and disassembly maintenance.

Description

technical field

[0001] The invention relates to an improvement of a bass mechanism of a musical instrument, in particular to a bass drive mechanism of an accordion bass machine. technical background:

[0002] The bass transmission mechanism of the accordion bass machine is the internal transmission mechanism of the accordion bass keyboard, and the pronunciation of the bass and harmony required by the performance is realized by the transmission mechanism. The bass keyboard is composed of multiple keys, each of which is connected with a top piece. Press the top piece push teeth on the key button to push the combined action of the column, roller, ejector rod, and starter frame to open the upper cover of the sound hole. pronounce. The current production process of the accordion bass machine is to use the ordinary soft aluminum plate L2Y2 without hardness to cut, bend and stamp it. The disadvantages are that the size is difficult to guarantee, the wear resistance is poor, the pr...
