Description

Technical Field

[0001] This utility model relates to the field of musical instrument tuning technology, and in particular to a self-locking guitar tuning peg. Background Technology

[0002] The guitar is often considered a primary instrument in pop, rock, blues, folk, and flamenco music. In classical music, it is often performed as a solo or duet. Of course, the guitar also plays a significant supporting role in chamber music and orchestral music. The sound of the guitar is produced by the vibration of its strings, one end of which is fixed to a tuning peg on the neck of the guitar. The tuning peg is often used to tune the guitar.

[0003] Patent CN203311831U discloses a closed guitar knob. This design allows the strings to pass through a locking hole of a locking pin. By rotating the knob, the locking pin moves up and down until the strings are locked in place, which has the advantage of being easy to use.

[0004] However, further investigation revealed the following problems with the solution: the operation of locking the strings is relatively complicated. The strings must first pass through the locking hole of the locking pin, and then the locking button must be rotated to move the locking pin in order to lock the strings in place. In addition, there are many parts on the tuning peg, which not only makes the tuning peg heavy but also makes the assembly process cumbersome. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a self-locking guitar tuning peg. This invention has the function of self-locking the guitar strings, which simplifies the operation steps of locking the strings, reduces the weight of the tuning peg, and also simplifies the assembly steps of the tuning peg.

[0006] The technical solution adopted by this utility model is as follows: A self-locking guitar tuning peg includes a housing, a transmission assembly, a string-locking assembly, and a handle. The transmission assembly is disposed inside the housing, and the handle and the string-locking assembly are respectively disposed at both ends of the housing. The handle is connected to the string-locking assembly via the transmission assembly. The string-locking assembly includes a transmission shaft and a string post detachably connected to the transmission shaft. The transmission shaft is connected to the transmission assembly. The string post has a locking hole and an assembly hole communicating with the locking hole. The locking hole is used for the string to pass through, and the assembly hole is used for the transmission shaft to extend into. When the string post is connected to the transmission shaft in place, the end of the transmission shaft extends into the locking hole along the assembly hole and abuts against the string.

[0007] The drive shaft is provided with a threaded section, and the chord column is provided with a threaded hole that communicates with the assembly hole. The threaded section and the threaded hole are threadedly engaged.

[0008] The drive shaft is also provided with a clamping shaft. When the string post is connected to the drive shaft, the clamping shaft extends into the lock hole along the assembly hole to clamp the string. The end of the clamping shaft that extends into the lock hole is provided with an arc surface.

[0009] The end face of the string column away from the drive shaft has a recessed groove for tool insertion.

[0010] The axis of the lock hole intersects perpendicularly with that of the mounting hole.

[0011] The transmission assembly includes a worm gear and a worm that mesh with each other. The handle is connected to the worm, and the transmission shaft is connected to the worm gear. The handle drives the worm gear and the transmission shaft to rotate through the worm.

[0012] The housing has an annular platform inside, which is sandwiched between the drive shaft and the worm gear. The worm gear has a protrusion that abuts against the annular platform.

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0020] like Figures 1 to 5 As shown, this is an embodiment of the present invention: a self-locking guitar tuning peg, including a housing 1, a transmission assembly, a string-locking assembly, and a handle 2. The transmission assembly is disposed inside the housing 1. The handle 2 and the string-locking assembly are respectively disposed at both ends of the housing 1, and the handle 2 is connected to the string-locking assembly via the transmission assembly. The string-locking assembly includes a transmission shaft 3 and a pin 4 detachably connected to the transmission shaft 3. The transmission shaft 3 is connected to the transmission assembly. The pin 4 has a locking hole 5 and an assembly hole 6 communicating with the locking hole 5. The locking hole 5 is used for the string to pass through, and the assembly hole 6 is used for the transmission shaft 3 to extend into. When the pin 4 and the transmission shaft 3 are connected in place, the end of the transmission shaft 3 extends into the locking hole 5 along the assembly hole 6 and abuts against the string.

[0021] The beneficial effects of this design are as follows: This utility model has a self-locking function for the strings. The string locking assembly adopts a detachable drive shaft and string post. When the string post and drive shaft are connected in place, the end of the drive shaft directly extends into the lock hole and presses against the string, realizing one-step locking of the string. This simplifies the operation steps of locking the string, improves tuning efficiency and ease of use, and avoids the cumbersome process of first passing through the lock hole and then rotating the lock button in the prior art. The string locking assembly has a compact structure, significantly reducing the number of parts and the overall weight of the string button, while also simplifying the assembly steps of the string button.

[0022] Further, the drive shaft 3 is provided with a threaded section 7, and the chord column 4 is provided with a threaded hole 8 that communicates with the assembly hole 6, and the threaded section 7 and the threaded hole 8 are threadedly engaged.

[0023] The beneficial effects of this design are as follows: through the threaded engagement of the threaded section and the threaded hole, a stable and reliable connection and power transmission between the drive shaft and the string post are achieved. Not only is the structure simple and easy to assemble, but the self-locking characteristic of the thread is also utilized to effectively prevent the string post from loosening during vibration, ensuring the long-term stability of the locked string. The threaded engagement provides precise feed control for the drive shaft end to press against the string, making the locking force more uniform and controllable.

[0024] Furthermore, the transmission shaft 3 is also provided with a clamping shaft 9. When the string post 4 is connected to the transmission shaft 3, the clamping shaft 9 extends into the lock hole 5 along the assembly hole 6 to clamp the string, and the end of the clamping shaft 9 that extends into the lock hole 5 is provided with an arc surface 10.

[0025] The benefits of this design are as follows: by using a clamping shaft with an arc-shaped end, it can gently and evenly press the strings in a surface-to-surface manner when inserted into the lock hole. This arc-shaped design effectively avoids cuts or stress concentrations on the strings caused by sharp edges or right angles, significantly reducing the risk of string damage during the locking process, thereby extending the lifespan of the strings and helping to maintain the stability and purity of the tone.

[0026] Furthermore, the end face of the string post 4 away from the transmission shaft 3 is recessed with a groove 11 for tool insertion.

[0027] The advantages of this design are as follows: In this embodiment, the groove is a flat slot, allowing for the use of standard tools such as a flathead screwdriver for locking and engaging. The strings can be loosened by rotating the tuning peg counterclockwise. This design also greatly facilitates the initial installation or fine-tuning of the tuning peg. This simplifies the assembly process, especially in situations where pre-adjustment of the tuning peg is required before string installation. Precise control can be achieved without relying entirely on the handle, improving operational convenience and efficiency.

[0028] Furthermore, the axes of the lock hole 5 and the assembly hole 6 are perpendicularly intersected.

[0029] The advantages of this design are as follows: by setting the axes of the lock hole and the mounting hole to intersect perpendicularly, the clamping shaft can directly and efficiently clamp the string passing through the lock hole radially. This orthogonal layout is compact, with the shortest force transmission path and no force loss, ensuring the sensitivity and reliability of the locking action, while simplifying the machining process of the internal channels.

[0030] In a further configuration, the transmission assembly includes a worm gear 12 and a worm 13 that mesh with each other. The handle 2 is connected to the worm 13, and the transmission shaft 3 is connected to the worm gear 12. The handle 2 drives the worm gear 12 and the transmission shaft 3 to rotate through the worm 13.

[0031] The advantages of this design are as follows: The worm gear and worm transmission combination, utilizing its inherent self-locking characteristics, effectively prevents the handle from reversing under force, ensuring pitch stability after tuning. Simultaneously, this structure has a large transmission ratio, making tuning operations more precise and effortless, improving feel and control accuracy.

[0032] Further, the housing 1 is provided with an annular platform 14 inside, the annular platform 14 is sandwiched between the transmission shaft 3 and the worm gear 12, the worm gear 12 has a protrusion 15 that abuts against the annular platform 14, the transmission shaft 3 is also provided with a connecting shaft 16 that passes through the annular platform 14, and the worm gear 12 is connected to the connecting shaft 16 by a fastener 17.

[0033] The beneficial effects of this design are as follows: the abutment between the ring platform and the boss provides precise axial positioning and support for the worm gear, effectively limiting the axial movement of the transmission components and enhancing transmission stability and reliability. The design of the connecting shaft passing through the ring platform ensures the alignment of the worm gear and the transmission shaft, making power transmission smoother. At the same time, this structure facilitates assembly and independent maintenance of each component. In this embodiment, the fasteners are screws using existing technology.

[0034] Furthermore, the lock hole 5 is a through hole that passes through the string post 4, and the two ends of the string post 4 corresponding to the lock hole 5 are provided with chamfered corners 18.

[0035] The beneficial effects of this design are as follows: the lock hole is a through hole, which makes it easy for the strings to pass through; the rounded corners at both ends can effectively prevent the sharp edges of the hole from scratching or wearing the strings during the string threading or locking process, thus protecting the strings and extending their service life, while making the string threading operation smoother and more fluid.

[0036] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
