Supporting frame used for electronic piano

Abstract

The invention discloses a supporting frame used for an electronic piano. The supporting frame comprises a supporting plate and a piano box, a placement plate is arranged in the piano box, the two endsof the placement plate are in sliding connection with the inner wall of the piano box through sliders, and the tow ends on the bottom surface of the placement plate are connected with the internal bottom surface of the piano box through hydraulic telescoping rods. One outer side of the piano box is connected with a cover plate through hinges, the two ends on the back side of the piano box are provided with vertical columns, L-shaped connecting rods are rotationally connected in the vertical columns, and supporting blocks are arranged at the upper ends of the L-shaped connecting rods. The twoends on the surface of the supporting plate are provided with sleeves, adjusting rods are arranged in the sleeves, the adjusting rods are fixedly connected with the sleeves through tightening bolts, and the tops of the adjusting rods are fixedly connected with the bottom surface of the piano box. By means of the supporting frame, the electronic piano is stably placed, the supporting frame is convenient to use, the electronic piano is placed in the piano box when not in use, the dustproof and waterproof effects are good, the electronic piano is not prone to collision or falling or damage, the placement height of the electronic piano is easy to adjust, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of electronic piano auxiliary equipment, in particular to a support frame for an electronic piano. Background technique [0002] An electric piano is an electroacoustic musical instrument. It emerged in the 1960s and 1970s, and was popular in the 1980s and early 1990s as a musical instrument used to replace the piano on some occasions. The sounding principle of the electric piano is to use the keyboard as an on-off switch to form electrophoresis. Once the key is pressed, the internal crystal oscillator starts to work, forming a pulse to generate a waveform of a certain frequency, which is then amplified by the frequency divider and sent to the speaker for sound. When the electronic piano is in use, it is usually placed on a fixed support frame. The traditional piano support frame has a single functional structure and poor applicability. The height of the piano cannot be adjusted after placement, which will ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a support frame for an electronic piano to solve the problem that the traditional piano support frame in the prior art has a single functional structure, poor applicability, and the height of the piano after placement cannot be adjusted. It will be a big inconvenience, and the electronic piano is placed directly on the support frame without protection and cover. The surface of the electronic piano is easy to accumulate and adhere to dust, or it will be damaged by moisture and water.
