Description

Technical Field

[0001] The utility model relates to the technical field of guitar musical instruments, in particular to an improved guitar tuning device. Background Art

[0002] Guitar is a plucked instrument that produces sound by plucking the guitar strings with fingers to generate vibrations. In order to make the guitar produce the expected sound, a guitar tuning device is needed to adjust the tightness of the guitar strings before playing the guitar. The guitar tuning device is usually installed at the end of the guitar and is intertwined with the guitar strings. When the tightness of the strings needs to be adjusted, the guitar tuning device can be rotated to loosen or tighten the strings wrapped thereon, and then the strings can be gently stroked to judge whether the tightness is appropriate by the sound produced. The adjustment is relatively convenient and simple.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, it still has certain defects: after the existing tuning device is twisted for tuning multiple times, the rotation will wear and consume the lubricating oil in the tuning device, resulting in uneven rotation during the tuning process and blockage. It is difficult to accurately control the rotation angle, and it is necessary to frequently disassemble and add lubricating fluid and readjust the strings. The maintenance cycle is short, and the disassembly and reassembly are very complicated, requiring the use of multiple tools, which is inconvenient to use. Utility Model Content

[0004] The utility model aims to provide an improved guitar tuning device with a long maintenance period, anti-blocking and convenient use 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 improved guitar tuning device, comprising a connecting handle and a mounting plate arranged at the end of the connecting handle, wherein a plurality of tuners are embedded on the mounting plate, wherein the tuners include a mounting block embedded in the mounting plate and a tuning shaft movably engaged with the inner wall of the mounting block, wherein a thermal lubrication device having one side in contact with the outer wall of the tuning shaft is further provided in the mounting block, and after the lubricating fluid between the tuning shaft and the mounting block is consumed, the tuning shaft is twisted quickly to cause friction and heat generation between the tuning shaft and the mounting block, thereby generating thermal expansion and extrusion, and the thermal lubrication device outputs the lubricating fluid to be smeared on the tuning shaft.

[0006] A further improvement is that a twisting handle is also provided at the upper end of the winding axis.

[0007] A further improvement is that: the lower end of the winding shaft is also provided with a friction disk whose outer wall and the inner wall of the mounting block are in contact with each other.

[0008] A further improvement is that a friction bulge is provided on the inner wall of the mounting block at a position corresponding to the friction disc.

[0009] A further improvement is that the thermal lubrication device includes an oil tank embedded in the mounting block and an air pressure tank arranged in the oil tank, an air pressure plate is sealingly and slidably arranged between the oil tank and the air pressure tank, one side of the air pressure tank is provided with a compressed air pipeline connected to the air pressure tank, the inner wall of the compressed air pipeline is sealed and slidably provided with a compressed air rack, the end of the compressed air rack away from the compressed air pipeline is provided with a pressure sliding block that fits into the outer wall of the winding shaft, and the side of the oil tank close to the winding shaft is provided with a pressure one-way pipeline connected to the oil tank.

[0010] A further improvement is that a plurality of arc-shaped grooves are provided on the surface of the air pressure plate close to the air pressure chamber.

[0011] A further improvement is that an oil pipe connected to the oil tank is provided on the side of the oil tank away from the winding axis.

[0012] A further improvement is that a tubular sponge column is provided at one end of the pressure one-way pipe close to the string-winding axis.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: after the lubricating liquid between the winding shaft and the mounting block is consumed, the winding shaft can be twisted quickly to make it expand by friction, and then the expansion squeezes the thermal lubrication device to squeeze out the lubricating liquid in the oil tank and apply it to the surface of the winding shaft, preventing the winding shaft from becoming dry and difficult to rotate to control the angle, and at the same time greatly extending the maintenance cycle, making the disassembly frequency lower and more convenient to use.
