Description

Tuning device for piano

Technical Field

The utility model belongs to the technical field of the piano maintenance apparatus, concretely relates to piano is with transfer law device.

Background

The piano mainly produces sound, namely, a wooden soundboard which is fully tensioned with nearly 230 strings is connected with a cast iron frame; the 220 strings are divided into several groups to form a string system: the average tension of each string is about 90 kg, and the total tension of the whole piano is about 20 tons; the tuning of the piano is a relatively complex work, a tuning operator not only needs to tune the tone, but also needs to debug all mechanical parts of the piano normally, so that all systems are recovered to be normal, the good performance and the music effect of the piano are fully exerted, a tuning tool is only a tuning wrench, and the tuning wrench is a special tool for rotating a piano string shaft pin to adjust the tension of a string so as to raise or lower the tone; however, the existing piano tuning devices are all in the process of driving the adjusting head to rotate and tune by rotating the handle, and in the process, the force cannot be accurately controlled, and tuning adjustment cannot be accurately carried out; therefore, a tuning device for a piano, which is convenient to operate and accurate in tuning, is required.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of prior art, and provide a convenient operation, tuning is accurate for piano temperament device.

The purpose of the utility model is realized like this: the utility model provides a temperament device for piano, includes device head and handle, the overhead draw-in groove of having seted up of device, the draw-in groove comprises circular draw-in groove and the mutual intercommunication of rectangle draw-in groove, be provided with the fixed head in the circular draw-in groove, the below threaded connection of fixed head has the regulation head, the outside fixedly connected with gear of fixed head, the rectangle draw-in groove internal rotation is connected with the worm with gear intermeshing, the overhead top of device is provided with the calibrated scale, the scale mark has been carved on the calibrated scale, the symmetry is provided with the indicateing arm on the gear upper surface.

And the handle is provided with an anti-slip rubber sleeve.

The tail of the handle is provided with a hanging hole.

The adjustment head has a variety of sizes.

The dial comprises left dial and right dial, the middle part of left dial and right dial is provided with the scale mark of returning to 0.

The utility model has the advantages that: when the utility model is used, a proper adjusting head can be selected according to the type of the piano pin to be adjusted, then the adjusting head is in threaded connection with the fixed head, the worm is stirred by hands, and the gear is driven to rotate under the rotation of the worm, so that the indicator on the gear is aligned with the 0-returning scale mark; then, the adjusting head is sleeved with the piano pin, the worm is shifted by hand, the gear is driven to rotate under the rotation of the worm, and then the fixing head is driven to rotate, so that the adjusting head is driven to rotate, and the effect of fastening the piano pin is achieved; the indicating signs are arranged on the gear, and the indicating signs rotate synchronously along with the rotation of the gear, so that the rotation angle can be easily known, and the adjustment strength can be determined according to the rotation angle of the indicating signs, thereby achieving the purpose of accurate tuning; the dial consists of a left dial and a right dial, and indicator marks are symmetrically arranged on the gear, so that a left-hand user and a right-hand user can be satisfied at the same time, and the left-hand user and the right-hand user can both use the dial conveniently; when the tuning tool is used, a user can complete tuning work by one hand, and the condition that the tuning cannot be performed while sound testing and tuning are performed by two hands simultaneously is avoided; the utility model drives the gear to rotate by rotating the poking worm, so that the adjusting head rotates more slowly, and the tuning process is more accurate; the user can control the force more easily, and the phenomenon that the string is broken due to inaccurate force control is avoided; in a word, the utility model has the advantages of convenient operation, accurate tuning.
