Multi-point acoustic guitar side plate shape-forming support device

Abstract

The invention discloses a cross-shaped acoustic guitar side plate shape-forming bracket, which comprises two parallel adjusting flat plates. Each of two ends of the adjusting flat plates are connectedwith an adjusting rod via a rotating shaft; the top ends of the adjusting rods on the same side are connected with supporting plates through rotating shafts; horizontal supporting rods are connectedto one sides of the supporting plates; an adjusting screw rod is arranged between the adjusting flat plates; one end of the adjusting screw rod is movably connected to one adjusting flat plate, and the other end of the adjusting screw rod passes through the other adjusting flat plate and is threadingly connected to the adjusting flat plate; longitudinal threaded sleeves are arranged on opposite outer sides of the adjusting flat plates; longitudinal supporting rods are connected in the longitudinal threaded sleeves; and the longitudinal supporting rods have outer threaded sections matching thelongitudinal threaded sleeves. The invention is easy to use, is good in shape-forming effect, is wide in application range, and is easy to store.

Description

technical field [0001] The invention relates to a shaped support frame for a guitar side plate, in particular to a multi-point shaped support device for an acoustic guitar side plate. Background technique [0002] The side panel of the acoustic guitar is embedded between the front panel and the back panel, enclosing the piano box into a gourd-shaped board. If the acoustic guitar is erected, the side panels are the top and the curved parts on both sides from top to bottom. The upper shoulders, the waist of the middle concave part, the lower shoulders of the curved parts on both sides of the lower side and the bottom bottom. In the process of making the side panels, the bendable wood pieces are bent in the mold, and the inner cavity of the mold The shape is consistent with the panel of the acoustic guitar, which is gourd-shaped. It is formed by applying glue in the mold, and then connected with the panel to form a complete piano case. [0003] After the wood chip is bent in t...

Problems solved by technology

However, since the current acoustic guitar is still mainly made by hand, and there is no professional equipment for the production of the side panels, especially the shaping part, the current method used is to nail two wooden strips into a cross shape, and according to the mold The width of the inner left and right depressions (that is, the depression of the waist of the gourd-shaped panel) and the distance between the upper and lower centers are used to select the length of the wooden strips, and made into a stereotyped bracket, pressing the left and right and downwards. live

However, there are many defects in the use of this stereotyped bracket: 1. The length of the wooden strip is fixed. During long-term use, the length is shortened due to wear and tear. The bolt fills the gap, which is very inconvenient to operate, and the bolt is easy to fall off, which affects the shaping effect; 2. Acoustic guitars of different sizes need to make brackets of different sizes, which is easy to be confused when using, and also increases the number of brackets, which is not easy to store; 3 1. The cross-shaped bracket can only support the four points of up, down, left, and right, while the upper and lower shoulders are not supported. When the wood chips are not bent properly, these two places are also prone to gaps, resulting in improper shaping. Complete, poorly shaped defects
