This large-scale piano key pole of high strength has increased the reinforced wood, and the increase of thickness in the balance hole department of key pole body all is hardwood then intensity is increased about adding like this, has avoided the key pole body because of the problem that long-term use warp.

Description

High-strength large piano key rod

Technical Field

The utility model belongs to the technical field of the piano, concretely relates to large-scale piano key pole of high strength.

Background

The key bar of the piano keyboard is generally made of high-quality spruce, the thickness of the key bar is about 24 mm due to the material specification, the piano standard and the process consideration, and the length of the key bar is determined according to the size and the design of the piano. The key rod with the same thickness has no problem in small and medium-sized pianos, but the large piano has insufficient strength due to the overlong key rod, so that the playing hand feeling and sensitivity are influenced, and the good use requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a large-scale piano key pole of high strength to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a large-scale piano keybar of high strength, includes the keyboard tray, the supporting shoe is connected to the one end of keyboard tray, the supporting shoe passes through the connecting rod and rotates connection keybar body and well bedplate, well bedplate is fixed in the up end of keybar body, be equipped with on the relative keybar body lower terminal surface of well bedplate and strengthen the wood.

Preferably, the lower end of the connecting rod is rotatably connected with the supporting block.

Preferably, the support block is fixed to one end of the keyboard tray by screws.

The utility model discloses a technological effect and advantage: this large-scale piano key pole of high strength has increased the reinforced wood, and the increase of thickness in the balance hole department of key pole body all is hardwood then intensity is increased about adding like this, has avoided the key pole body because of the problem that long-term use warp.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a keyboard frame; 2. a key lever body; 3. a support block; 4. a connecting rod; 5. reinforcing wood; 6. a middle seat board.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a large-scale piano keybar of high strength as shown in fig. 1, including keyboard tray 1, supporting shoe 3 is connected to keyboard tray 1's one end, supporting shoe 3 passes through the screw fixation in keyboard tray 1's one end, supporting shoe 3 rotates through connecting rod 4 and connects keybar body 2 and well bedplate 6, the lower extreme of connecting rod 4 rotates with supporting shoe 3 to be connected, well bedplate 6 is fixed at the up end of keybar body 2, be equipped with reinforced wood 5 on the terminal surface under the relative keybar body 2 of well bedplate 6. The middle seat plate 6 is changed from the common length of 50-60 mm to 80 mm, and a reinforcing wood 5 with the length of 120 mm is stuck at the balance hole under the key rod.

Thus, the thickness at the balance hole is increased plus the strength is increased with hardwoods at both the top and bottom.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
