Abstract
Description
Technical Field
[0001] This utility model relates to a musical instrument tuning tool, specifically a tuning wrench. Background Technology
[0002] When musical instruments are used for a long time or left idle, they may become out of tune. Therefore, users need to adjust and correct the pitch when playing instruments (such as the guzheng). Currently, traditional tuning wrenches require a lot of force to turn, and some preschool children do not have enough strength to adjust them themselves, making it difficult to tune the strings and easy to break the strings. In addition, existing tuning wrenches cannot fine-tune the tuning pegs, and the large range of rotation of the tuning wrench increases the difficulty of pitch adjustment. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a tuning wrench that reduces speed and increases torque through planetary reduction of a planetary reducer. When adjusting the tuning pin, less force is required, the rotation force is more even, and the tuning is more accurate.
[0004] This utility model is achieved through the following technical solution: a tuning wrench, including a planetary reducer;
[0005] The planetary reducer includes an output shaft and an input shaft;
[0006] The input shaft provides power for the rotation of the output shaft; the output shaft is used to adjust the rotation of the string pins of the musical instrument, thereby adjusting the pitch of the instrument.
[0007] As a preferred embodiment of the tuning wrench described in this utility model: a locking support rod is also hinged to the side wall of the planetary reducer; the locking support rod is engaged with the input shaft.
[0008] As a preferred embodiment of the tuning wrench described in this utility model: the output shaft has an adjustment cavity that matches the tuning pin.
[0009] As a preferred embodiment of the tuning wrench described in this utility model: a knob handle that engages with the locking support rod is mounted on the input shaft.
[0010] As a preferred embodiment of the tuning wrench described in this utility model, a handle is also installed on the side wall of the planetary reducer.
[0011] As a preferred embodiment of the tuning wrench described in this utility model, the grip installation position should not obstruct the opening / closing of the locking support rod. Attached Figure Description

[0020] This utility model structure not only fulfills the functions of a traditional tuning wrench, but also has a fine-tuning function, making the rotation force more even and the pitch more accurate; users with less strength (children) can adjust it through the knob handle of the planetary reducer to complete the understanding and learning of tuning. Detailed Implementation
[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0024] Reference Figure 1-4 As a first embodiment of the present invention, a tuning wrench is provided, including a planetary reducer 1;
[0025] The planetary reducer 1 includes an output shaft 2, an input shaft 4, a sun gear, and a planet carrier, etc. Since the planetary reducer 1 is an existing structure and belongs to existing technology, its internal structure and working principle will not be described further.
[0026] The input shaft 4 provides power for the rotation of the output shaft 2; the output shaft 2 is used to adjust the rotation of the string pins of the musical instrument, thereby adjusting the pitch of the musical instrument.
[0027] A locking support rod 7 is hinged to the side wall of the planetary reducer 1; the locking support rod 7 is engaged with the knob handle 5 on the input shaft 4.
[0028] The output shaft 2 has an adjustment cavity 3 that matches the string pin.
[0029] A knob handle 5 is mounted on the input shaft 4 and engages with the locking support rod 7.
[0030] A handle 6 is also installed on the side wall of the planetary reducer 1.
[0031] Specifically, the planetary reducer 1 of this utility model includes, but is not limited to, a single-stage, a double-stage, or a triple-stage reduction gear. The selection of different speed ratios should be determined according to the user's different forces.
[0032] When the locking support rod 7 is locked onto the knob handle 5, the knob handle 5 cannot be rotated. At this time, rotating the grip 6 drives the output shaft 2 to directly adjust the string pin and adjust the pitch. This adjustment function is the same as that of a traditional tuning wrench.
[0033] When the locking support rod 7 is opened and no longer locked onto the knob handle 5, the knob handle 5 can be rotated. At this time, rotating the knob handle 5 on the input shaft 4 will drive the output shaft 2 to rotate, thereby enabling fine-tuning of the instrument's string pins. This function is also suitable for users with less strength to adjust the string pins, ensuring even force distribution and preventing the strings 11 from breaking.
[0034] The grip 6 should be installed in a position that does not obstruct the opening / closing of the locking support rod 7.
[0035] Specifically, the positions of the grip 6 and the locking support rod 7 are not limited, but they must not interfere with each other's use of their own functions.
[0036] Reference Figure 4 and Figure 5Taking the guzheng as an example, open the tuning box 9 on the main body 8 of the guzheng. When plucking the strings to test the sound, determine the string 11 that needs tuning and identify the corresponding tuning peg 10. Insert the adjustment chamber 3 on the output shaft 2 into the corresponding tuning peg 10. Use the locking support rod 7 to close and lock it onto the knob handle 5. At this time, the knob handle 5 cannot be turned. Turn the grip 6 to drive the output shaft 2 to directly adjust the tuning peg and adjust the pitch. Determine whether fine adjustment is needed. If fine adjustment of the tuning peg 10 is needed, open the locking support rod 7 and it is no longer locked onto the knob handle 5. Relying on the contact support between the grip 6 and the bottom of the tuning box 9, rotate the knob handle 5. Turn the knob handle 5 on the input shaft 4 to drive the output shaft 2 to rotate and achieve fine adjustment of the instrument's tuning peg. If you have less strength or are a beginner, you can use fine adjustment throughout the process, which is convenient for beginners to operate and feel the changes in pitch.
[0037] Reference Figure 6 and Figure 7 When adjusting the string pins 10 at the end of the tuning box 9, the pitch can be adjusted by placing the locking support rod 7 at the bottom of the other string pins 10 and fine-tuning as described above.
[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
