TECHNICAL FIELD

[0001] The utility model relates to triangle piano technical field especially triangle piano cast iron plate front frame dustproof plate. BACKGROUND

[0002] Piano is a kind of keyboard instrument, and piano is composed of keys (including white keys and black keys) and metal string sound board. After piano is used for a period of time, dust, chaff, hair impurities are easy to accumulate in the position of cast iron plate front frame, and because of the densely packed pegs and strings in this position, it is not only not easy to clean, but also the hygroscopicity of dust accumulation for a long time can cause rust and unattractive.

[0003] Therefore, it is necessary to provide a new triangle piano cast iron plate front frame dustproof plate to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0004] To solve the above technical problems, the utility model provides triangle piano cast iron plate front frame dustproof plate.

[0005] The triangle piano cast iron plate front frame dustproof plate provided by the utility model comprises a wood board, the number of wood boards is two, two symmetrically arranged through cavities are formed in the two wood boards, an elastic cloth is arranged above the two wood boards, the elastic cloth is sleeved on the two wood boards and is fixed on the wood boards by nails, and an elastic strip is arranged below the two wood boards and is fixed on the elastic cloth.

[0006] Preferably, the material of the elastic cloth is acoustic sound transmission cloth.

[0007] Preferably, the material of the elastic strip is polyester and rubber thread.

[0008] Compared with the related art, the triangle piano cast iron plate front frame dustproof plate provided by the utility model has the following beneficial effects:

[0009] The triangle piano cast iron plate front frame dustproof plate provided by the utility model is placed on the cast iron plate front frame of the triangle piano when in use, the elastic cloth wrapped on the wood board is used for protection, dust, rubber chaff, hair and other impurities can be prevented from falling on the position of the triangle piano front frame, the cast iron plate front frame of the triangle piano is kept clean, the interior of the triangle piano is kept clean for a long time, the opportunity of rust of the pegs and strings is reduced, the triangle piano user can conveniently clean regularly when the device is directly taken down.
