Description

Technical fields:

[0001] This utility model relates to the field of foldable guitar technology, and in particular to a foldable guitar. Background technology:

[0002] Because guitars are generally large, foldable guitars have appeared on the market to facilitate carrying and storage. For example, Chinese utility model patent application number CN202322922833.0 discloses a two-section folding guitar, including a body, neck, and pivot structure. Although it can be folded and greatly reduced in overall length, making it easier to carry and store, it is done by folding the neck backward and fitting it to the rear of the body. This not only adds extra thickness after folding, resulting in a larger overall thickness, but also, since the neck often has a fretting mechanism and the body often has a plucking mechanism, folding the neck backward to shorten the overall length will inevitably cause one of the fretting or plucking mechanisms to be downward and under pressure when placed horizontally. Utility model content:

[0003] The purpose of this invention is to provide a foldable guitar that addresses the shortcomings of existing technologies. It shortens the overall length by folding without increasing the thickness, and the overall thickness after folding is small. When placed horizontally, it will not compress the fingering mechanism or the string plucking mechanism.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a foldable guitar, including a body, a neck, a pivot structure, a string plucking device on the body, and a string pressing device on the neck. The bottom side of the neck is hinged to the top side of the body through the pivot structure, and the neck can be rotatably fitted to one side of the body. When the neck is folded and fitted to one side of the body, the string plucking device on the body and the string pressing device on the neck are both facing upwards.

[0005] A further improvement to the above solution is that the rotating shaft structure includes a rotating shaft seat and two double-ended screws respectively inserted into the rotating shaft seat. Each double-ended screw includes a central shaft portion located in the middle and two threaded ends located at both ends. The two double-ended screws are respectively inserted into the rotating shaft through their central shaft portions. Nuts are threadedly connected to the two threaded ends of each double-ended screw. Rotating shaft assemblies are respectively provided on both sides of the central shaft portion of each double-ended screw. The rotating shaft assembly includes a connecting piece, a fixing washer, and an elastic washer. The connecting piece is configured to rotatably fit onto the double-ended screws. A movable washer is located on one side of the center rod of the double-ended screw. A fixed washer is used to securely fit onto one side of the center rod of the double-ended screw and abut against the movable washer. The end face of the movable washer that abuts against the fixed washer is a concave-convex surface extending around the axial direction. The end face of the fixed washer that abuts against the movable washer is also a matching concave-convex surface. An elastic washer is used to fit onto one side of the center rod of the double-ended screw and abut against at least the opposite sides of the movable and fixed washers. The movable washer, fixed washer, and elastic washer are sandwiched between the center rod and the nut. A connecting piece is used to connect to the body or neck of the instrument.

[0006] A further improvement to the above scheme is that the double-ended screw has a shaft through hole along the axial direction, and a side through hole connected to the shaft through hole is opened on the side of the central rod of the double-ended screw. The rotating shaft seat is formed with a through groove, and the side through holes of the two double-ended screws are connected through the through groove.

[0007] A further improvement to the above solution is that the rotating shaft assembly further includes a central washer and an end washer fitted on one side of the central rod of the double-ended screw. The central washer is used to abut against the central rod, and the end washer is used to abut against the nut.

[0008] A further improvement to the above scheme is that a central washer, a movable washer, a fixed washer, an elastic washer, and an end washer are arranged sequentially between the central rod and the nut.

[0009] A further improvement to the above solution is that the connecting piece has mounting holes.

[0010] A further improvement to the above solution is that the connecting piece and the movable washer are located on the same plane.

[0011] A further improvement to the above solution is that the connecting piece and the movable washer are integrally L-shaped.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a foldable guitar, including a body, a neck, a pivot structure, a plucking device on the body, and a pressing device on the neck. The bottom side of the neck is hinged to the top side of the body through the pivot structure, and the neck can be rotatably fitted to one side of the body. When the neck is folded and fitted to one side of the body, the plucking device on the body and the pressing device on the neck are both facing upwards.

[0013] Compared to existing folding guitars, this invention folds the neck to one side to shorten the overall length. While shortening the overall length, it does not add extra thickness. The overall thickness after folding is small. When the neck is folded and fitted to one side of the guitar body, the plucking mechanism on the guitar body and the fretting mechanism on the neck are both facing upwards. When placed horizontally, it will not compress the fretting mechanism or the plucking mechanism. Attached image description:

Detailed implementation method:

[0019] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-4As shown, this utility model includes a guitar body 1, a neck 2, a pivot structure 3, a plucking string device 4 mounted on the guitar body 1, and a pressing string device 5 mounted on the neck 2. The bottom side of the neck 2 is hinged to the top side of the guitar body 1 via the pivot structure 3, allowing the neck 2 to rotatably fit against one side of the guitar body 1. When the neck 2 is folded and fitted against one side of the guitar body 1, both the plucking string device 4 on the guitar body 1 and the pressing string device 5 on the neck 2 face upwards. Compared to existing folding guitars, this utility model folds the neck 2 to one side to shorten the overall length. While shortening the overall length through folding, it does not add extra thickness, resulting in a smaller overall thickness after folding. When the neck 2 is folded and fitted against one side of the guitar body 1, both the plucking string device 4 on the guitar body 1 and the pressing string device 5 on the neck 2 face upwards, preventing compression of the pressing string device 5 and the plucking string device 4 when placed horizontally.

[0020] The rotating shaft structure 3 includes a rotating shaft seat 31 and two double-ended screws 32 respectively inserted into the rotating shaft seat 31. Each double-ended screw 32 includes a central rod portion 321 located in the middle and two threaded ends 322 located at both ends. The two double-ended screws 32 are respectively inserted into the rotating shaft through the central rod portion 321. Nuts 33 are threadedly connected to the two threaded ends 322 of each double-ended screw 32. Rotating shaft assemblies 34 are respectively provided on both sides of the central rod portion 321 of the two double-ended screws 32. Component 34 includes a connecting piece 35, a fixing washer 36, and an elastic washer 37. The connecting piece 35 has a mounting hole 351, through which the connecting piece 35 is connected to the body 1 or the neck 2. The connecting piece 35 is provided with a movable washer 38 for rotatably fitting onto one side of the central rod portion 321 of the double-ended screw 32. The fixing washer 36 is fixedly fitted onto one side of the central rod portion 321 of the double-ended screw 32 and matches and abuts against the movable washer 38. The movable washer 38 abuts against the fixing washer. The end face of ring 36 is a concave-convex surface extending axially. The end face of the fixed washer 36, which abuts against the movable washer 38, is also a matching concave-convex surface. The elastic washer 37 is fitted onto one side of the central rod portion 321 of the double-ended screw 32 and at least abuts against the opposite sides of the movable washer 38 and the fixed washer 36. The movable washer 38, the fixed washer 36, and the elastic washer 37 are clamped between the central rod portion 321 and the nut 33. The connecting piece 35 is used to connect to the body 1 or the neck 2 of the instrument. The pivot structure 3 of this utility model... The specific working principle is similar to that of the rotating shaft structure 3 disclosed in Chinese Utility Model Patent Application No. CN202322922833.0, and will not be repeated here. The difference between the rotating shaft structure 3 of this utility model and that of the former is that the former includes four screws. This utility model replaces four screws with two double-headed screws 32, which not only reduces the number of parts and facilitates assembly, but also makes it easier to make the rotating shaft seat 31 thinner due to the absence of screw heads and shaft hole connection structures, thus making it easier to make the whole structure thinner.

[0021] The double-ended screw 32 has an axial through-hole 323, and the side of the central rod 321 of the double-ended screw 32 has a side through-hole 324 that communicates with the axial through-hole 323. The rotating shaft seat 31 is formed with a wire passage groove 311. The side through-holes 324 of the two double-ended screws 32 are connected through the wire passage groove 311. Through the cooperation of the axial through-hole 323, the side through-hole 324, and the wire passage groove 311, the wire can be inserted from the axial through-hole 323 of one double-ended screw 32 and then sequentially passed through the side through-hole 324 of the same double-ended screw 32, the wire passage groove 311 of the rotating shaft seat 31, and the side through-hole 324 of the other double-ended screw 32 before exiting from the axial through-hole 323 of the other double-ended screw 32. This enables the electrical connection between the body 1 and the neck 2, achieving not only aesthetically pleasing concealed wiring but also effectively reducing the risk of wire damage.

[0022] The rotating shaft assembly 34 also includes a center washer 39 and an end washer 40 fitted on one side of the center rod 321 of the double-ended screw 32. The center washer 39 is used to abut against the center rod 321, and the end washer 40 is used to abut against the nut 33. The center washer 39 and the end washer 40 can ensure that the force is received smoothly and reduce friction, thereby ensuring smoother overall rotation.

[0023] In this embodiment, a central washer 39, a movable washer 38, a fixed washer 36, an elastic washer 37, and an end washer 40 are arranged sequentially between the central rod 321 and the nut 33.

[0024] Compared to the connecting piece 35 and the movable washer 38 which are arranged perpendicularly to each other, the connecting piece 35 and the movable washer 38 of this utility model are located on the same plane, which not only makes the whole easier to process and manufacture, but also allows the whole to be made thinner.

[0025] If the connecting piece 35 is made too narrow, the connection strength will be insufficient. Compared to making the connecting piece 35 and the movable washer 38 both very wide, this utility model uses a structural design where the connecting piece 35 is relatively wide and the movable washer 38 is relatively narrow. The connecting piece 35 and the movable washer 38 together form an L-shaped structure, which meets the connection strength requirements while making the overall structure more compact and saving materials.

[0026] Working principle:

[0027] Fold the neck 2 upwards and unfold it to the top of the body 1 to complete the guitar's rotation and unfolding. Fold the neck 2 downwards and fold it to fit snugly against one side of the body 1 to complete the guitar's rotation and folding. Compared to existing folding guitars, this invention shortens the overall length by folding the neck 2 to one side. While shortening the overall length, it does not increase the thickness. The overall thickness after folding is small. When the neck 2 is folded and snugly against one side of the body 1, the plucking mechanism 4 on the body 1 and the fretting mechanism 5 on the neck 2 are both facing upwards. When placed horizontally, they will not be squeezed.

[0028] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
