Description

A horizontal piano sustain lever drive bushing

technical field

The utility model relates to the field of musical instrument parts and equipment, in particular to a transmission shaft sleeve for a horizontal piano sustain bar.

Background technique

The strings are the sound source of all stringed instruments. If the sound is not accurate, adjust the strings to achieve the standard pitch. The industrial name of the string is piano wire, which is a special steel wire specially made for the production of musical instruments. These strings of different lengths, diameters, and tensions are arranged in an orderly manner to form the sounding body of the piano, that is, the resonance plate, and the core of the resonance plate is composed of strings of different lengths, diameters, and tensions. The strings on the piano are divided into five sections when they are fixed, and the third section is the effective string length, that is, the vibration emitted by this section is transmitted to the soundboard and heard by us. The other 1st, 2nd, 4th and 5th chord lengths are invalid chord lengths, and the vibration is not transmitted to the soundboard. The principle of the double overtone column is to place a metal resonator on the fifth invalid string length to stimulate the vibration of the strings in this section, thereby emitting rich overtones. Many people say that Steinway's treble has a metallic tone, which is the effect of having rich overtones.

The U-shaped transmission rod currently on the market is fixedly welded on the sustainer rod, so it is not easy to change the angle and position.

Utility model content

The purpose of this utility is to overcome the shortcomings existing in the prior art, and provide a horizontal piano sustainer lever drive bushing, which uses the sustainer lever drive bushing to realize the problem that the U-shaped drive rod is not easy to change the angle and position , to solve the problems raised in the background art above.

In order to achieve the above purpose, the utility model provides the following technical solutions: a horizontal piano sustainer lever drive bushing, including a U-shaped transmission rod, a sustainer lever, a fixing screw, a sliding groove and a fixing block, the sustainer The driving rod passes through the sliding opening in the sliding groove and is fixed by a set screw; the two U-shaped rods of the U-shaped transmission rod are passed through the two circular holes on the side of the sliding groove; the side of the sustaining sound driving rod is fixed Welded with fixing blocks.

Preferably, the two U-shaped rods of the U-shaped transmission rod form a U-shaped structure, and the cross-sectional diameter of the U-shaped rods is slightly smaller than the inner diameter of the circular hole on the side of the slide groove.

Preferably, the damper rod is a cylindrical structure, and the diameter of the sustainer rod is slightly smaller than the inner diameter of the sliding opening in the sliding groove.

Preferably, the sliding groove is a cylindrical hollow structure.

Preferably, the side of the damper lever is fixedly welded with no less than three fixed blocks, and the distance between the fixed blocks is greater than the section length of the sliding groove.

Compared with the prior art, the beneficial effect of the utility model is that: the horizontal piano sustainer lever drive bushing adopts the sustainer lever drive bushing, and the U-shaped transmission rod is fixed with fixing screws, and the U-shaped transmission rod The position is adjusted by the nut. At the same time, the sustain lever moves inside the sliding groove. When the position is determined, it is fixed by screws. Its structure is simple and easy to use; it solves the problem that the U-shaped transmission rod is difficult to change the angle and position.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution: a horizontal piano sustain lever drive bushing, including U-shaped transmission rod 1, sustain lever 2, fixing screw 3, sliding groove 4 and The fixed block 5, the sustainer lever 2 passes through the sliding opening in the sliding groove 4, and is fixed by the fixing screw 3; the two U-shaped rods of the U-shaped transmission rod 1 pass through the two circles on the side of the sliding groove 4 On the shaped hole; the side of the sustainer lever 2 is fixedly welded with a fixed block 5 .

The two U-shaped rods of the U-shaped transmission rod 1 form a U-shaped structure, which solves the problem that the U-shaped transmission rod is not easy to change the angle and position. The cross-sectional diameter of the U-shaped rod is slightly smaller than the inner diameter of the circular hole on the side of the sliding groove 4. It is convenient for the U-shaped transmission rod 1 to be inserted into the circular hole on the side of the slide groove 4; the sustain tone lever 2 is a cylindrical structure, and the diameter of the sustain tone lever 2 is slightly smaller than the inner diameter of the slide port in the slide groove 4, and the tone sustain The driving rod 2 can be freely transmitted in the sliding opening in the sliding groove 4; the sliding groove 4 is a cylindrical hollow structure; The distance between the blocks 5 is greater than the section length of the sliding groove 4, which is convenient for the U-shaped transmission rod 1 arranged on the sliding groove 4 to change its position between the fixed blocks 5.
