Description

Technical Field

[0001] The utility model relates to the field of guzheng, in particular to a guzheng box body made of composite materials. Background Art

[0002] Traditional guzheng box bodies adopt wooden structures. However, wood is a porous material, and the levels of temperature and humidity will directly affect the water content of the wood, leading to water absorption and dehydration of the wood, which will cause the wood to expand and contract, resulting in changes in the physical properties of the wood itself, causing cracks in the guzheng box body, and ultimately affecting the sound quality of the guzheng, which needs to be improved. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a guzheng box body made of composite materials, which has the effect of preventing the deformation or cracking of the guzheng box body.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: A guzheng box body made of composite materials includes a panel, side plates, a back plate, a head plate, and a tail plate. The side plates are arranged on both sides of the panel and are integrally formed therewith. The head plate and the tail plate are arranged at both ends of the back plate and are integrally formed therewith. The panel, side plates, back plate, head plate, and tail plate are all made of carbon fiber composite materials and are buckled and adhesively fixed to form a box body structure with a hollow interior.

[0005] In a preferred example of the utility model, it can be further configured that: both the panel and the back plate include a skin layer and a foam core layer. The skin layer is made of carbon fiber composite material, and the foam core layer is located inside the skin layer.

[0006] In a preferred example of the utility model, it can be further configured that: the thickness of the foam core layer is 30 - 40 mm.

[0007] In a preferred example of the utility model, it can be further configured that: a film adhesive layer is arranged between the skin layer and the foam core layer.

[0008] In a preferred example of the utility model, it can be further configured that: the thickness of the film adhesive layer is 0.1 - 0.2 mm.

[0009] In a preferred example of the utility model, it can be further configured that: slots for installing sound beams and tuning peg plates are arranged on the inner sides of the side plates.

[0010] In a preferred example of the utility model, it can be further configured that: the height of the slots is 3 - 5 mm.

[0011] In summary, the utility model has the following beneficial effects:

[0012] 1. The guzheng box body is made of a composite of resin and fiber materials, insensitive to temperature and humidity changes, does not require special maintenance, and has no risk of deformation or cracking, thus being able to improve the sound quality of the guzheng and having stable quality performance;

[0013] 2. Multiple components of the guzheng box body are integrally formed. The composite material can form parts with relatively complex shapes, such as the front panel, side panels, bottom panel, head board, and tail board of the guzheng, which can be integrally formed through preliminary design, reducing the assembly time and the possibility of cracking;

[0014] 3. The guzheng box body uses carbon fiber composite materials, which are thinned and lightened. The strength of the composite material is much greater than that of wood, and the thickness of the sound board can be greatly reduced. The traditional guzheng weighs 7 - 10 kg and has a large volume, while the composite material guzheng weighs about 3 kg, greatly improving the portability of the guzheng.

[0020] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0021] As Figure 1 , Figure 2 shown, a composite material guzheng box body includes a front panel 1, side panels 2, a back panel 3, a head board 4, and a tail board 5. The side panels 2 are arranged on both sides of the front panel 1, and the two are integrally formed. The head board 4 and the tail board 5 are arranged at both ends of the back panel 3, and the three are integrally formed.

[0022] As Figure 1 , Figure 2 shown, the front panel 1, side panels 2, back panel 3, head board 4, and tail board 5 are all made of carbon fiber composite materials, and are buckled and bonded to each other to form a box body structure with a hollow interior.

[0023] As Figure 1 , Figure 2 , Figure 4As shown, both the panel 1 and the back panel 3 include a skin layer 11, a foam core layer 12, and a film layer 13. The skin layer 11 is made of a carbon fiber composite material. The foam core layer 12 is located inside the skin layer 11, and the thickness of the foam core layer 12 is 30 - 40 mm. The film layer 13 is located between the skin layer 11 and the foam core layer 12, and the thickness of the film layer 13 is 0.1 - 0.2 mm.

[0024] Therefore, the guzheng box body is made of a composite of resin and fiber materials, is not sensitive to changes in temperature and humidity, does not require special maintenance, and has no risk of deformation and cracking. Thus, it can improve the sound quality of the guzheng and has stable quality performance.

[0025] Multiple components of the guzheng box body are integrally formed. The composite material can form parts with relatively complex shapes, such as the panel 1 and the side panel 2, the bottom panel and the head panel 4, and the tail panel 5 of the guzheng, which can be integrally formed through preliminary design, reducing the assembly time and the possibility of cracking.

[0026] The guzheng box body uses a carbon fiber composite material, which reduces the thickness and weight. The strength of the composite material is much greater than that of wood, and the thickness of the soundboard can be greatly reduced. The traditional guzheng weighs 7 - 10 kg and has a large size, while the composite material guzheng weighs about 3 kg, greatly improving the portability of the guzheng.

[0027] As Figure 3 shown, a slot 6 for installing the sound beam and the tuning peg plate is provided on the inner side of the side panel 2. The height of the slot 6 is 3 - 5 mm, so as to achieve the rapid assembly of the sound beam and the tuning peg plate, making the production process of the guzheng easier and more convenient.

[0028] The specific embodiments are only explanations of the present invention and are not limitations thereof. Those skilled in the art can make modifications to the embodiments without creative contributions according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
