Description

Technical Field

[0001] The present invention relates to a guitar, and more particularly to a split guitar. Background Art

[0002] In the existing guitar industry, the conventional joining and assembling process of the neck and the body is to open a dovetail groove on the body, open a tenon on the bottom of the neck that matches the dovetail groove, and then use white glue for bonding. Assembling them together before painting makes it difficult to handle the joint during painting and grinding. Moreover, the components are bonded with white glue, resulting in an unstable structure and the headstock being prone to breakage; the white glue is prone to sliding during bonding, and the assembly accuracy is low. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a split guitar with a stable structure, high assembly accuracy, and easy handling of the joint.

[0004] In order to overcome the deficiencies of the prior art, another objective of the present invention is to provide a manufacturing method for a split guitar with a stable structure, high assembly accuracy, and easy handling of the joint.

[0005] One of the objectives of the present invention is achieved by the following technical solutions:

[0006] A split guitar includes a neck, a headstock, a headplate, a body, a connecting component, a pin, and a fastener. The connecting component includes a secondary material and a connecting rod. The headstock is fixed to one end of the neck by the pin. The other end of the neck is fixed to the headplate by the fastener. The secondary material is positioned relative to the neck by the pin. The connecting rod is received in the secondary material and its end extends into the neck. The headplate is installed in the body. The headplate is provided with a secondary material fixing hole. The connecting rod is provided with a mounting hole. The secondary material is provided with a threaded hole. A screw passes through the secondary material fixing hole and the mounting hole on the connecting rod and is fixed to the threaded hole to fix the secondary material to the headplate.

[0007] Further, the included angle between the neck and the headstock is 16°.

[0008] Further, the body includes a faceplate. The faceplate is provided with a neck mounting groove. The end of the neck is embedded in the neck mounting groove.

[0009] Further, the body includes side plates. The side plates are provided with secondary material mounting grooves. The secondary material is provided with a second mounting surface. The shape of the secondary material mounting groove corresponds to the shape of the second mounting surface. The second mounting surface is embedded in the secondary material mounting groove.

[0010] Further, the headplate is provided with a second mounting groove. The second mounting surface is installed in the second mounting groove.

[0011] Furthermore, the connecting component further includes a patch which is received in the second mounting groove and located between the head plate and the auxiliary material.

[0012] Furthermore, the head plate is provided with a first mounting groove and a neck fixing hole. The neck fixing hole is located within the first mounting groove. The end of the neck is received in the first mounting groove, and the fastener passes through the neck and cooperates with the neck fixing hole.

[0013] The second object of the present invention is achieved by the following technical solution:

[0014] A method for manufacturing a split guitar for manufacturing the above split guitar, comprising the following steps:

[0015] Component manufacturing: separately manufacture different components of different guitars;

[0016] Partial assembly: Use dowel pins for positioning between the fingerboard and the neck, use dowel pins for positioning between the neck and the headstock, fix the neck and the head plate with fasteners, and use dowel pins for positioning between the auxiliary material and the neck;

[0017] Painting: Paint the components after partial assembly;

[0018] Polishing: Polish the components after partial assembly;

[0019] Full assembly: Install the head plate on the barrel body, insert the connecting rod into the auxiliary material, and fix the head plate and the auxiliary material with screws.

[0020] Furthermore, the included angle between the neck and the headstock is 16°.

[0021] Furthermore, the included angle between the neck and the vertical direction is 88°.

[0022] Compared with the prior art, the split guitar of the present invention has the following advantages:

[0023] (1) Save wood, and the components can be spliced by multiple small pieces of wood;

[0024] (2) Can be manufactured separately. After partially assembling the fingerboard, neck, headstock, and auxiliary material, paint them, and then perform assembly, reducing the operation difficulty of workers and improving the finished product rate;

[0025] (3) The greater the angle of the headstock, the greater the string tension and the better the resonance. With good resonance, the tone of the guitar is more solid and has a more granular feeling, but it is prone to breakage at the headstock. By changing the original white glue bonding to dowel pin positioning, the connection force between the headstock and the neck is enhanced. On the basis that the headstock is not easily broken, the angle of the headstock can be made larger, from the original 14° to 16°, resulting in a better tone of the guitar;

[0026] (4) By changing the original white glue bonding to pin positioning, the problem of easy sliding during white glue bonding is avoided, and the assembly accuracy is improved;

[0027] (5) By changing the original white glue bonding to pin positioning, the overall structure is stable. BRIEF DESCRIPTION OF THE DRAWINGS
