Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of musical instruments, in particular to an adjusting device for adjusting the angle of a guitar scale line. Background Art
[0002] Guitar is a plucked instrument that produces sound by plucking the guitar strings with fingers to generate vibrations. The guitar mainly produces sound through the guitar strings, that is, the scale wires. The scale wires are an important part of the guitar. Different scale wires are made of a variety of different elastic materials and can produce sounds of different styles. After the scale wires are installed on the guitar, the scale wires are prone to deviation during use or installation, which results in multiple scale wires not being kept on the same plane. At this time, an adjustment device is required to adjust the angle of the scale wires so that the scale wires are on the same plane for better and more convenient playing. The adjustment device clamps and fixes the scale wires through the front fixture. After fixation, the scale wires can be adjusted by manually pulling the adjustment device. It is convenient and quick to use, and at the same time, it prevents the scale wires from cutting the user's hands during the adjustment process, which is safer.
[0003] Although the above-mentioned prior art can solve the corresponding technical problems, it still has certain defects: during the adjustment process of the existing adjustment device, when adjusting the angle of the thinner scale wire, due to the low strength of the thinner scale wire, it is easy to cause the adjustment device to apply too much pressure on the scale wire when fixing the scale wire, thereby generating a groove weak point on the surface of the scale wire. When the guitar is installed in the guitar for playing, if the player plays more vigorously, it is easy to cause the weak point to be repeatedly stressed and cause the scale wire to break, thereby making the scale wire more fragile and reducing its service life. Utility Model Content
[0004] The utility model aims to provide an adjusting device for adjusting the angle of a guitar scale line, which can protect the scale line and avoid reducing the life of the scale line, in view of the defects and shortcomings of the prior art.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an adjustment device for adjusting the angle of a guitar scale line, comprising a first inner pressure handle and a second inner pressure handle whose middle section is movably engaged with the first inner pressure handle, the first inner pressure handle comprising a handle body and a clamping block arranged at the end of the handle body, a buffer cavity is arranged in the clamping block, and a buffer reinforcement block connected to the buffer cavity is also arranged on the side of the clamping block contacting the scale line; when adjusting, the scale line contacts the buffer reinforcement block and squeezes the second inner pressure handle and the handle body, so that the second inner pressure handle and the clamping block squeeze and fix the scale line, and the excessive squeezing force is absorbed by the buffer cavity and the buffer reinforcement block.
[0006] A further improvement is that: the bottom of the first inner pressure handle is covered with an anti-slip cover.
[0007] A further improvement is that: the bottom of the second inner pressure handle is covered with an anti-slip cover.
[0008] A further improvement is that a plurality of pressure-resistant columns are arranged in the buffer cavity, and a hollow ball made of elastic material is arranged in the middle section of the pressure-resistant column.
[0009] A further improvement is that an air flow channel communicating with the buffer cavity is also provided on the other side of the clamping block.
[0010] A further improvement is that the buffer reinforcement block includes an air pressure plate arranged on the side of the clamping block contacting the scale line and an elastic pressure plate arranged on one side of the air pressure plate, and the elastic pressure plate is embedded with a plurality of air pressure pipes connected to the inner wall of the air pressure plate, and the other side of the air pressure plate is also provided with an exhaust pipe connected to the inner wall of the air pressure plate and the buffer cavity, a blocking block is provided in the exhaust pipe, and a freely movable closing ball is also provided in the exhaust pipe.
[0011] A further improvement is that a pull-back spring is provided between the outer wall of the closing ball and the inner wall of the exhaust pipe.

[0013] A further improvement is that a friction pressure plate is provided on the end of the compressed air pipe located on the outer wall of the elastic pressing plate.
[0014] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when adjusting the scale line, the utility model can insert the scale line into the position of the buffer reinforcement block, and at the same time squeeze the first inner pressure handle and the second inner pressure handle from both sides, so that the first inner pressure handle and the second inner pressure handle are contracted and then fixed, and pressure is applied to the elastic pressing sheet to squeeze out the air inside it. At this time, the adsorption force on the scale line can be generated through the air pressure tube, and at the same time, the elastic pressing sheet is deformed to absorb the excessive pressure, and the buffer cavity cooperates to fully release and absorb the excessive pressure, thereby ensuring the fixing effect while not generating indentations on the surface of the scale line, the adjusted scale line is not easy to break, and has a long service life.

[0019] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.
[0020] See also Figure 1-3As shown, the technical solution adopted in this specific embodiment is: an adjustment device for adjusting the angle of the guitar scale line, comprising a first inner pressure handle 1 and a second inner pressure handle 2 whose middle section is movably engaged with the first inner pressure handle 1, wherein the first inner pressure handle 1 comprises a handle body 11 and a clamping block 12 arranged at the end of the handle body 11, wherein a buffer cavity 13 is arranged in the clamping block 12, and a buffer reinforcement block 15 connected to the buffer cavity 13 is further arranged on the side of the clamping block 12 contacting the scale line, wherein the buffer reinforcement block 15 comprises an air pressure plate 21 arranged on the side of the clamping block 12 contacting the scale line and an air pressure plate 21 arranged on the side of the air pressure plate 21 The elastic pressing sheet 22 on the side is embedded with a plurality of compressed air pipes 23 connected to the inner wall of the air pressure plate 21. The other side of the air pressure plate 21 is also provided with an exhaust pipe 25 connected to the inner wall of the air pressure plate 21 and the buffer cavity 13. A blocking block 26 is provided in the exhaust pipe 25. A freely movable closing ball 27 is also provided in the exhaust pipe 25. When adjusting, the scale line contacts the buffer reinforcement block 15 and squeezes the second inner pressure handle 2 and the handle body 11, so that the second inner pressure handle 2 and the clamping block 12 squeeze the fixed scale line, and absorbs the excessive pressure through the buffer cavity 13 and the buffer reinforcement block 15. When using the squeezing force, install the scale wire that needs to be adjusted between the top of the first inner pressing handle 1 and the top of the second inner pressing handle 2, and align the outer wall of the scale wire with the buffer reinforcement block 15, then press the first inner pressing handle 1 and the second inner pressing handle 2 internally, so that the top of the first inner pressing handle 1 and the top of the second inner pressing handle 2 fit each other, and continue to apply force. At this time, the scale wire can squeeze the elastic pressing piece 22 of the buffer reinforcement block 15, so that it is squeezed and deformed, and the air inside it is pressed into the air pressure plate 21, and the air is discharged from the exhaust pipe 25. At the same time, the air pressure pushes the closing ball 27 outward, causing it to lose its fit with the blocking block 26, and then Expel the gas and then loosen it slightly to allow the elastic pressing sheet 22 to recover slightly. At this time, the gas will flow back from the exhaust pipe 25, pushing the closing ball 27 so that the closing ball 27 is blocked at the blocking block 26, and the exhaust pipe 25 is closed. At this time, the air pressure difference can generate suction at the air pressure pipe 23, thereby adsorbing and fixing the surface of the scale line, and at the same time, additional reinforcement is performed in conjunction with the applied pressure. When the pressure is too large, it can be buffered and absorbed by the elastic pressing sheet 22 and the buffer cavity 13, thereby ensuring the fixing effect while not generating indentations on the surface of the scale line. The adjusted scale line is not easy to break and has a long service life.
[0021] The bottom of the first internal pressure handle 1 is provided with an anti-slip cover 3, which is helpful to avoid slipping during the internal pressure process and make the force transmission smoother;
[0022] The bottom of the second internal pressure handle 2 is covered with an anti-slip cover 3, which is helpful to avoid slipping during the internal pressure process and make the force transmission smoother;
[0023] The buffer cavity 13 is provided with a plurality of anti-pressure columns 14, and two are provided in this embodiment. The middle section of the anti-pressure column 14 is provided with a hollow ball made of elastic material, which is conducive to generating elastic force when the buffer cavity 13 is deformed when the pressure is too large, and then absorbing the pressure and converting it into elastic force to be flexibly applied to the scale line without affecting the fixing effect;
[0024] The other side of the clamping block 12 is also provided with an air flow channel connected to the buffer cavity 13, which is conducive to exhausting the air generated by extrusion;
[0025] A pull-back spring 28 is provided between the outer wall of the closing ball 27 and the inner wall of the exhaust pipe 25, which is conducive to enabling the closing ball 27 to recover and fit on the blocking block 26 more quickly after the air is squeezed out, thereby generating a more stable and stronger suction force at the compressed air pipe 23;
[0026] The outer wall of one end of the exhaust pipe 25 located in the air pressure plate 21 is provided with an air collecting sheet 29, which is conducive to collecting the compressed air over a larger area so that the gas can be discharged better;
[0027] The end of the compressed air pipe 23 located on the outer wall of the elastic pressing plate 22 is provided with a friction pressure plate 24, which is beneficial to increase the fitting effect between the end of the compressed air pipe 23 and the scale line, and provide friction resistance, further enhancing the fixing effect.
[0028] Working principle of the utility model: When the utility model is used, the scale line that needs to be adjusted is installed between the top of the first inner pressure handle 1 and the top of the second inner pressure handle 2, and the outer wall thereof is aligned with the buffer reinforcement block 15, and then the first inner pressure handle 1 and the second inner pressure handle 2 are pressed internally, so that the top of the first inner pressure handle 1 and the top of the second inner pressure handle 2 fit each other, and force is continuously applied, at this time, the scale line can squeeze the elastic pressing sheet 22 of the buffer reinforcement block 15, so that it is squeezed and deformed, and the air inside it is pressed into the air pressure plate 21, and the air is discharged from the exhaust pipe 25, and at the same time, the closed ball 27 is pushed outward by air pressure, so that it loses contact with the blocking block 2 6, and then the gas is discharged, and then slightly loosened, the elastic pressing sheet 22 can be slightly restored, and the gas will flow back from the exhaust pipe 25, pushing the closing ball 27 so that the closing ball 27 is blocked at the blocking block 26, and the exhaust pipe 25 is closed. At this time, the air pressure difference can generate suction at the pressure pipe 23, and then the surface of the scale line is adsorbed and fixed, and at the same time, additional reinforcement is performed with the applied pressure, and when the pressure is too large, it can be buffered and absorbed by the elastic pressing sheet 22 and the buffer cavity 13, thereby ensuring the fixing effect while not generating indentations on the surface of the scale line, the adjusted scale line is not easy to break, and has a long service life.
