Technical Field

[0001] The utility model relates to the field of guqin groove belly, in particular to a guqin groove belly structure. Background Art

[0002] The guqin, also known as the yaoqin, jade qin, or seven-stringed qin, is a traditional Chinese plucked string instrument with a history of over 3,000 years. It is considered one of the eight musical instruments, the silk instrument. It boasts a wide range, deep timbre, and a long-lasting lingering sound. The trough, the space between the guqin's arched top and bottom plates, is carved into its interior.

[0003] In actual use by people in this field, the internal parts of the existing troughs are all carved, which may lead to carving errors. After carving errors, the entire instrument body cannot be used due to the wrong sound reception, which results in a waste of materials and the craftsmen's time. Therefore, a trough belly structure for guqin is proposed to solve the above problems. Utility Model Content

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4 As shown, a guqin groove-belly structure includes a guqin body 1, a groove-belly body 2 is formed on one side of the guqin body 1, a neck 3 is provided on one side of the guqin body 1, a first sound receiving device 4 is provided inside the groove-belly body 2, a second sound receiving device 5 is provided inside the groove-belly body 2, a fixing assembly 6 is provided inside the first sound receiving device 4, a fixing post 7 is provided inside the guqin body 1, an insertion slot 8 is formed on one side of the first sound receiving device 4, the fixing post 7 is inserted into the insertion slot 8, and a clamping slot 9 is formed on both sides of the fixing post 7;

[0023] During operation, the trough belly body 2 is generally carved by craftsmen, so it is inevitable that the first Na Yin 4 will be carved incorrectly. When the first Na Yin 4 is carved incorrectly, it is only necessary to carve the first Na Yin 4 into a fixed column 7 and open a slot 9 on the fixed column 7. After that, the prefabricated first Na Yin 4 can be taken out and then put on the outside of the fixed column 7. In this way, the fixed column 7 is inserted into the inside of the plug-in slot 8 and then fixed by the fixing component 6.

[0024] Furthermore, the card slot 9 includes a bidirectional screw rod 601, two movable plates 602 and two insertion rods 603. The bidirectional screw rod 601 is rotatably connected to the inside of the first ring 4. The two movable plates 602 are symmetrically slidably connected to the inside of the first ring 4, and the movable plate 602 is threadedly connected to the outside of the bidirectional screw rod 601. The two insertion rods 603 are fixedly connected to one side of the corresponding movable plate 602.

[0025] During operation, the bidirectional screw rod 601 is rotated, and the threaded cooperation between the bidirectional screw rod 601 and the movable plate 602 will drive the two movable plates 602 to move toward each other, so that the insertion rod 603 is inserted into the interior of the card slot 9, thereby fixing the first sound box 4 on the fixed column 7. In this way, even if the engraving fails, the prefabricated first sound box 4 can be used to avoid the waste of the entire piano body 1. Since the movable plate 602 cannot rotate, and the connection positions of the two movable plates 602 and the bidirectional screw rod 601 are different, the moving directions are also different.

[0026] Furthermore, a chute 10 is provided inside the first sound sensor 4, and a slide plate 11 is fixedly connected to one side of the movable plate 602, and the slide plate 11 is slidably connected to the inside of the chute 10;

[0027] During operation, this enables the movable plate 602 to move smoothly inside the first sensor 4.

[0028] Furthermore, a ball 12 is rotatably connected to one side of the slide 11, and the ball 12 contacts the inner wall of the chute 10;

[0029] During operation, the balls 12 can reduce friction, thereby making the movable plate 602 move more easily.

[0030] Furthermore, one end of the bidirectional screw rod 601 extends to the outside of the first sound box 4, and the end of the bidirectional screw rod 601 located outside the first sound box 4 is fixedly connected to the handle 13;

[0031] During operation, the bidirectional screw rod 601 can be conveniently rotated by the handle 13 .

[0032] Furthermore, two symmetrically distributed concave grooves 14 are provided inside the groove belly body 2, and the cross section of the concave groove 14 is a "V"-shaped combined with circular arc design;

[0033] During operation, the concave grooves 14 are provided to increase the harmonics of the vibration when playing the piano. The shape of the concave grooves 14 is a "V" shape combined with an arc design. The harmonics enter the concave grooves 14 to produce resonance, and the reflection of the arc is more rounded, which can make the tone more rounded, with vicissitudes and ancient charm, thereby making the sound of the piano more charming.

[0034] Furthermore, the width of the concave groove 14 is 20 mm to 40 mm.

[0035] This size makes it easy for craftsmen to carve when working.

[0036] Working principle: The trough belly body 2 is generally carved by craftsmen, so it is inevitable that there will be mistakes in carving the first Na Yin 4. When the first Na Yin 4 is carved incorrectly, it is only necessary to carve the first Na Yin 4 into a fixed column 7 and open a slot 9 on the fixed column 7. Then, the prefabricated first Na Yin 4 can be taken out and then put on the outside of the fixed column 7. In this way, the fixed column 7 is inserted into the inside of the plug-in slot 8, and the bidirectional screw rod 601 is rotated at the same time. Then, the threaded fit between the bidirectional screw rod 601 and the movable plate 602 will drive the two movable plates 602 to move. Move toward each other, so that the insertion rod 603 is inserted into the interior of the card slot 9, thereby fixing the first sound box 4 on the fixed column 7. In this way, even if the engraving fails, the prefabricated first sound box 4 can be used to avoid wasting the entire piano body 1. The second sound box 5 can also use this method. By setting the concave groove 14, the harmonics of vibration when playing the piano are increased. The shape of the concave groove 14 is a "V" shape combined with an arc design. The harmonics enter the concave groove 14 to resonate, and the reflection of the arc is more rounded, which can make the tone more rounded, vicissitudes of life and ancient charm, thereby making the sound of the piano more charming.
