Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument temperament adjustment equipment, in particular to a piano temperament adjustment tool. Background Art

[0002] To put it simply, piano tuning is to tighten the strings to reach the standard pitch, but piano tuning is a more complicated job. The tuner not only needs to tune the piano accurately, but also needs to adjust the mechanical parts of the piano to make each system return to normal. Tools are needed to adjust the piano, and the mute clip is one of them.

[0003] In the middle range of a piano, one note is composed of three strings. When a tuner is adjusting a note, in order to accurately find the string that needs to be adjusted, the tuner usually fixes the other two strings and lets the string being tested sound alone, so as to perform precise tuning. A mute clip is a tool for fixing the strings. However, when using the existing mute clip, on the one hand, the strings are thin, and the tuner needs to accurately insert the slender mute clip between the two strings that need to be fixed, which is inconvenient for the tuner to operate. On the other hand, the mute clip fixes the two strings by inserting and squeezing them, which will cause wear on the strings, and long-term squeezing will cause metal fatigue of the strings, reducing the service life of the strings. Utility Model Content

[0004] The utility model discloses a piano tuning tool, aiming to solve the technical problems that the existing piano mute clip is inconvenient for the tuner to operate and reduces the service life of the piano strings.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A piano tuning tool comprises a handle, wherein a fixing mechanism is arranged inside the handle; the fixing mechanism comprises three sliding parts slidably distributed inside the handle, a pushing block is fixed on the top of the sliding part, a clamping part is arranged on the outside of the sliding part, and a spring is horizontally connected between the inner side of the sliding part and the interlayer inside the handle.

[0007] By providing three separate sliding parts and setting the outer side of the sliding part as a snap-fit ​​structure, each string can be individually fixed using the snap-fit ​​part. On the one hand, it can reduce the damage to the strings when the tool is used. On the other hand, the user can freely change the number of clamped strings according to needs, and the functionality is richer.

[0008] In a preferred embodiment, positioning mechanisms are provided on both sides of the outside of the handle; the positioning mechanisms include positioning plates rotatably mounted on both sides of the outside of the handle, and the side ends of the positioning plates and the handle's rotatable mounting locations are rotatably connected to a pressure plate, which fits the outside of the handle.

[0009] By providing a freely rotatable positioning plate structure, the user pinches the pressure plate to control the rotation of the positioning plate. When the two positioning plates are located on both sides of the three strings, the side ends of the three sliding parts can be aligned with the three strings, so that the user does not need to carefully observe the position of the strings, making the tool more convenient to use.

[0010] In a preferred solution, a spring block is connected between the positioning plate and the outer side of the handle, a limit block is horizontally fixed to the outer side of the handle, and the side end of the pressure plate is sleeved inside the limit block.

[0011] The spring block is provided to provide power for the reset rotation of the positioning plate, and the limit block restricts the pressure plate, so that the pressure plate fits the side end of the handle and does not reverse outward, thereby ensuring the convenience and perfection of the tool when used.

[0012] In a preferred solution, a rubber pad is fixed to one side of the positioning plate close to the handle, and sponge strips are symmetrically fixed to both sides of the inner wall of the engaging portion.

[0013] The rubber pad and the sponge strip structure are provided to contact the strings, thereby reducing the wear of the strings when the tool is in use.

[0014] As can be seen from the above, the piano temperament adjustment tool provided by the utility model has the following improvements and effects compared with the prior art:

[0015] First, three separate sliding parts are provided inside the handle, and the outer side of the sliding part is provided as a snap-fit ​​structure, so that each string can be individually fixed by using the snap-fit ​​part. On the one hand, it can reduce the damage to the strings when the tool is used, and on the other hand, the user can freely change the number of clamped strings according to needs, making the functionality richer.

[0016] Secondly, by providing a positioning plate structure, the user pinches the pressure plate to control the rotation of the positioning plate. When the two positioning plates are located on both sides of the three strings, the pressure plate is released, and the automatically reset rotating positioning plates will be engaged on both sides of the three strings, so that the side ends of the three sliding parts can be aligned with the three strings, thereby eliminating the need for the user to carefully observe the position of the strings and omitting the calibration step, making the tool more convenient to use.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] The utility model discloses a piano temperament adjustment tool which is mainly used in the scene of piano temperament adjustment.

[0025] Reference Figures 1 to 4 A piano tuning tool comprises a handle 1, wherein a fixing mechanism 2 is arranged inside the handle 1; the fixing mechanism 2 comprises three sliding parts 201 slidably distributed inside the handle 1, a pushing block 202 is fixed on the top of the sliding part 201, a clamping part 203 is arranged on the outer side of the sliding part 201, and a spring 204 is horizontally connected between the inner side of the sliding part 201 and the interlayer inside the handle 1.

[0026] In this embodiment: when the user needs to adjust the piano temperament, the user needs to first hold the handle 1, and align the side end of the handle 1 with the three strings of the temperament that need to be adjusted, and push the two pushing blocks 202 in sequence, so that the sliding part 201 at the bottom of the pushing block 202 overcomes the resistance of the spring 204 and moves outward, and the clamping part 203 located on the outside of the sliding part 201 will move synchronously and clamp into the outside of the string at the corresponding position. At this time, the user presses the corresponding key on the piano to drive the corresponding hammer to strike the three strings, among which the two clamped strings cannot make a sound, while the unfixed strings make a sound. The user then decides whether to adjust according to the timbre, and repeats this process to debug the three strings separately, thereby completing the adjustment work.

[0027] It should be additionally explained that: a sliding groove 3 is provided on the top of the handle 1 , and the push block 202 passes through the inside of the sliding groove 3 , and the sliding groove 3 provides space for the movement of the push block 202 .

[0028] Reference Figures 1 to 3 In a preferred embodiment, positioning mechanisms 4 are provided on both sides of the outside of the handle 1; the positioning mechanisms 4 include positioning plates 401 rotatably mounted on both sides of the outside of the handle 1, and the side ends of the positioning plates 401 and the handle 1 where they are rotatably mounted are rotatably connected to a pressing plate 402, which is attached to the outside of the handle 1.

[0029] In this embodiment: when the user needs to adjust the piano pitch, the user needs to first hold the handle 1 and press the pressure plates 402 located on both sides of the handle 1. The pressure plates 402 under force drive the positioning plates 401 to rotate, thereby increasing the angle between the two positioning plates 401, and align the two positioning plates 401 with the outside of the three strings that need to adjust the pitch, and fit the handle 1 to the three strings. The reset positioning plates 401 will be slightly clamped on the outside of the three strings to complete the positioning.

[0030] Among them, it should be supplemented that: a spring block 403 is connected between the positioning plate 401 and the outer side of the handle 1; the user presses the pressure plate 402 to increase the angle between the two positioning plates 401, and aligns the two positioning plates 401 with the outer sides of the three strings that need to be adjusted. Then, as the user fits the handle 1 to the three strings, the user releases his hand pressing the pressure plate 402, and the spring block 403, which is no longer affected by the pulling force, shrinks and deforms, thereby driving the two positioning plates 401 to reset and rotate, and lightly clamp them on the outer sides of the three strings, thereby completing the positioning work.

[0031] Further, it is supplemented that a limit block 404 is fixed horizontally on the outer side of the handle 1, and the side end of the pressure plate 402 is sleeved inside the limit block 404. The limit block 404 restricts the pressure plate 402 to prevent the pressure plate 402 from folding outward.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, a rubber pad 405 is fixed to one side of the positioning plate 401 close to the handle 1 , and sponge strips 205 are symmetrically fixed to both sides of the inner wall of the engaging portion 203 .

[0033] In this embodiment: when the positioning plate 401 is lightly clamped on the outside of the three strings, the rubber pad 405 located at the side end of the positioning plate 401 will contact the strings, and when the engaging portion 203 is engaged with the outside of the strings, two symmetrically distributed sponge strips 205 will contact the strings; the rubber pad 405 and the sponge strips 205 can reduce the wear of the tool on the strings.

[0034] Working principle: When the user needs to adjust the piano tuning, the user needs to hold the handle 1 and press the pressure plates 402 on both sides of the handle 1. The pressure plates 402 under force drive the positioning plates 401 to rotate, thereby increasing the angle between the two positioning plates 401, and aligning the two positioning plates 401 with the outside of the three strings that need to adjust the tuning, and fitting the handle 1 to the three strings. The reset positioning plates 401 will be slightly clamped on the outside of the three strings to complete the positioning, and then the user pushes the two push blocks in turn. 202, causing the sliding portion 201 at the bottom of the pushing block 202 to overcome the resistance of the spring 204 and move outward, and the engaging portion 203 located on the outer side of the sliding portion 201 will move synchronously and engage with the outer side of the string at the corresponding position. At this time, the user presses the corresponding key on the piano to drive the corresponding hammer to strike the three strings, of which the two engaged strings cannot make a sound, while the unfixed strings make a sound. The user then decides whether to adjust according to the timbre, and repeats this process to adjust the three strings separately, thereby completing the adjustment work.

[0035] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
