Description

Subassembly convenient to piano assembly

Technical Field

The utility model relates to a piano assembly technical field especially relates to an subassembly convenient to piano assembly.

Background

With the improvement of living standard of people, the requirements on living quality are higher and higher. The demand of people on the piano is continuously improved, particularly, the education of vast children and teenagers needs a large number of pianos, the manufacturing industry of the pianos is started, and the problems of production efficiency and production quality are solved.

The main components of the piano are mark, shell, keyboard, hammer and pedal. The mark is a string system assembly of the piano, and belongs to a sound source part of the piano; the shell is used for decoration of the outer surface of the piano and protection of the inner structure, and comprises a central disc, a piano cover, piano legs, a top cover, side walls (commonly called ears), side plates and the like, wherein the central disc is used for placing a keyboard.

The assembly sequence of the prior piano production is mainly that piano shell side plates on two sides of a mark are firstly installed, then a middle plate is connected with the side plates, a leg support middle plate is installed, and finally a keyboard, a string hitting hammer and other parts inside the piano are installed. However, the assembly method is easy to cause damage to the shell, the installation of the keyboard, the hammer and other parts is time-consuming and labor-consuming, and the adjustment of the internal strings is more inconvenient.

Detailed Description

The technical solution of the present invention is further explained by the accompanying drawings and examples.

Example 1

With reference to fig. 1 to 2, an assembly for facilitating piano assembly is provided, which includes a middle plate holder 1, a mark fixing plate 2, and a connecting plate 3. The middle disc fixing frame 1 and the mark fixing plate 2 are fixedly connected through two ends of the connecting plate 3, the connecting plate 3 is vertically connected with the middle disc fixing frame 1 and the mark fixing plate 2, and the connecting plate 3 is shortest in length in the connecting direction when in vertical connection, so that plates are saved. In some embodiments, the central disc fixing frame 1, the mark fixing plate 2 and the connecting plate 3 are integrally formed, so that the product structure is more stable.

The central disc fixing frame 1 comprises a side plate 11 and a bottom plate 12, the side plate 11 and the bottom plate 12 are used for limiting the length and the height direction of the central disc 6 respectively, and two central disc fixing frames 1 are arranged on two sides of the central disc 6 to fix the central disc 6. All set up screw hole 4 on well dish mount 1 and the mark fixed

plate

2, 4 screw holes 4 evenly arrange on the mark fixed plate 2, evenly arrange 3 screw holes 4 respectively on curb plate 11 and the bottom plate 12 for with 6 side of well dish and bottom surface fixed connection.

With reference to fig. 3 to 4, when the product is used, the mark fixing plate 2 and the mark 5 are fixedly connected by using screws, the middle disc fixing frame 1 and the middle disc 6 are fixedly connected, at the moment, the middle disc 6 and the mark 5 are connected into a whole, the structure is stable, then, components such as a keyboard, a hammer and the like can be installed on the middle disc 6, a sound source system can be adjusted at any time, and after the internal structure is installed and debugged, a piano shell is finally installed.
