Description

Technical Field

[0001] The utility model relates to the technical field of stringed instruments, in particular to a magnetic adsorption type truss rod adjusting mechanism for stringed instruments. Background Technique

[0002] The neck of a stringed instrument such as a wooden guitar is prone to bending due to the changes in the use environment, the replacement of guitar strings of different specifications, or the tension generated by adjusting different tones, and a truss rod is required for precise adjustment. The truss rod of a stringed instrument is a steel bar or rod that passes through the inside of the neck and under the fingerboard, and keeps the neck straight by resisting the tension of the strings and the natural tendency of the wood. Nuts are provided at one or both ends of the truss rod, and its tension is adjusted by the nuts. When the truss rod is loosened, the neck will be slightly bent due to the tension of the strings. When the truss rod is tightened, the truss rod resists the tension of the strings to straighten the neck.

[0003] There are two styles of the structure of the existing truss rod. The first is a steel bar type truss rod built into the guitar. When the guitar fingerboard is bent, an Allen wrench is inserted to rotate the truss rod to adjust the tightness of the guitar fingerboard so that the guitar fingerboard returns to being straight. The second is a spoke nut truss rod, which is connected to the screw by welding a spoke nut, and the guitar fingerboard is made straight by rotating the spoke.

[0004] The truss rod of an old guitar is located at the rear of the neck. Adjusting the tightness of the neck requires tools such as a screwdriver to complete, and the guitar guard plate or the neck needs to be removed in advance. This structure requires an Allen wrench to adjust the truss rod, which is easy to cause scratches or damage to the guitar panel and strings. The truss rod of a newer guitar is located behind the nut or at the bottom of the neck, without a cover, and an Allen wrench is required for adjustment. This structure adjusts the truss rod by welding a spoke nut, and the installation and disassembly are cumbersome. If a part fails during use, it cannot be repaired. Content of the Utility Model

[0026] Refer to Figures 1 - 6 A magnetic adsorption type truss rod adjusting mechanism for a stringed instrument, which includes a detachably connected magnetic adsorption terminal 1 and a main body 2. The magnetic adsorption terminal 1 includes: a rotating head 11, a connecting rod 12 connected to the rotating head 11, and a magnetic adsorption head 13 disposed at the end of the connecting rod 12 and integrally provided with the connecting rod 12; an external angle wrench 14 connected to the end of the magnetic adsorption head 13. The external angle wrench 14 includes an internal connection part 142 installed inside the magnetic adsorption head 13 and the connecting rod 12, and an external connection part 141 extending to the outside of the magnetic adsorption head 13; the main body 2 includes a spoke 21 and an internal angle nut 22. A screw rod is provided inside the spoke 21, and the bending degree of the spoke 21 can be adjusted by a nut and the screw rod.

[0027] The internal angle nut 22 is detachably connected to the external connection part 141 of the external angle wrench 14. The external angle wrench 14 is an external hexagonal screw or an external octagonal screw, and the corresponding internal angle nut 22 is an internal hexagonal nut or an internal octagonal nut. The rotating head 11 is provided with a plurality of adjustment holes. The magnetic adsorption head 13 is a permanent magnet.

[0028] The magnetic adsorption head 13 is a hollow structure. The connecting rod 12 is provided with an internal connection cavity. The length of the internal connection part 142 of the external angle wrench 14 is greater than the length of the magnetic adsorption head 13, and the internal connection part 142 is fixedly connected to the internal connection cavity of the connecting rod 12. The length of the magnetic adsorption head 13 is L1, and the length of the connecting rod 12 is L2. In a preferred manner, L1:L2 is 0.25 - 0.5.

[0029] When the magnetic adsorption type truss rod adjusting mechanism for a stringed instrument is in use, the magnetic adsorption terminal 1 of the truss rod is detached from the main body 2, the main body 2 is installed and connected to the neck of the instrument, the stringed instrument is stably placed, and the magnetic adsorption head 13 is positioned at the adjusting position of the truss rod. The magnetic adsorption head 13 is a permanent magnet and can be adsorbed on the truss rod for convenient adjustment.

[0030] A connection is established between the inner joint portion 142 of the external angle wrench 14 and the magnetic suction head 13. By inserting a pin-shaped tool into the adjustment hole, or directly manually connecting and fixing the external joint portion 141 of the external angle wrench 14 of the magnetic suction terminal 1 to the internal angle nut 22 on the main body 2.

[0031] By inserting a pin-shaped tool into the rotating head 11, the rotating head 11 is provided with a number of adjustment holes, and fine adjustment can be carried out through different holes. The pin-shaped tool is inserted into the rotating head 11 and drives the rotating head 11 to rotate. The external angle wrench 14 and the internal angle nut 22 are driven to rotate through the connecting rod 12 and the magnetic suction head 13, and the internal angle nut 22 adjusts the tension of the truss rod through the screw rod inside the spoke 21. Once the truss rod is adjusted to the appropriate position, the tension of the adjusted truss rod can be maintained.

[0032] After fixation, check whether the string height and playing performance of the stringed instrument meet the expectations. If necessary, further fine-tuning can be carried out. After confirming that the adjustment result is satisfactory, the pin-shaped tool can be removed to complete the entire adjustment process. After the adjustment is completed, the stringed instrument can be reused for playing, and the truss rod will remain in the adjusted tension state to maintain the tone and playing performance of the instrument.

[0033] When the magnetic suction terminal 1 and the main body 2 need to be replaced after long-term use, a pin-shaped tool can be inserted into the adjustment hole, and the magnetic suction terminal 1 can be moved in the direction opposite to the main body 2 to separate the magnetic suction terminal 1 from the main body 2, which is convenient for replacement and maintenance.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
