Abstract
The invention discloses a bass upper nut convenient to switch the number of semicircular chord grooves. A long groove with the cross section being a regular triangle and the two ends being opened is formed in the upper end of a square strip; an adaptive regular triangular prism is arranged in the long groove; four semicircular chord grooves, five semicircular chord grooves and six semicircular chord grooves which are uniformly arranged are respectively formed in three rectangular side faces of the regular triangular prism along the length direction; the bottom end of each semicircular chord groove is higher than the upper end of the square strip; threaded holes are respectively formed in the left end and the right end of the regular triangular prism; square baffle plates are respectively arranged on the left end and the right end of the square strip; circular concave holes and communicated circular through holes are formed in the square baffle plates; after hexagon socket screws are screwed into the threaded holes, the regular triangular prism can be locked in the long groove. The bass upper nut has the advantage that the number of the semicircular chord grooves can be easily switched without replacing the square strip.
Description
Technical field
The present invention relates to musical instrument fitting technical field, capotasto on especially a kind of bass being convenient to switch semicircle string slot quantity.
Background technology
On common bass, capotasto is that square rectangular upper end edge length direction is provided with 4 uniform semicircle string slots, 5 semicircle string slots or 6 semicircle string slots, length direction and the square rectangular length direction of semicircle string slot are 90 ° of right angles, and the diameter of semicircle string slot is slightly larger than the diameter of corresponding string.Fix on the scroll head on the top of fingerboard because the strong viscose glue of square rectangular employing is adhesively fixed, and every root square rectangular on semicircle string slot quantity be changeless, when needs change string quantity, must change simultaneously there is the square rectangular of identical semicircle string slot quantity, operationally quite bother.
Summary of the invention
The object of this invention is to provide a kind of without the need to changing capotasto on the square rectangular bass that easily can switch semicircle string slot quantity.
Technical scheme of the present invention is: manufacture and design capotasto on a kind of bass being convenient to switch semicircle string slot quantity, comprise square rectangular, described square rectangular lower end adopts strong viscose glue to be adhesively fixed to fix on the scroll head on the top of fingerboard, principal feature of the present invention is: the center line of described square rectangular upper end edge length direction is provided with the elongated slot that square section is equilateral triangle, both ends open, be provided with adaptive regular triangular prism in described elongated slot, the length of side of the equilateral triangle at the left and right two ends of described regular triangular prism is longer than the length of side of the cross section equilateral triangle of elongated slot.
Three rectangle sides of described regular triangular prism are respectively equipped with 4 uniform semicircle string slots, 5 semicircle string slots and 6 semicircle string slots along its length.
Bottom in described semicircle string slot is higher than square rectangular upper end.
The left and right two ends of described regular triangular prism are respectively equipped with threaded hole, square rectangular left and right two ends are respectively equipped with square baffle plate, the width dimensions of described square baffle plate is identical with height dimension with square rectangular width dimensions respectively with height dimension, square baffle plate and square rectangular between adopt strong viscose glue gluing fixing.
The round tube hole that described square baffle plate is provided with round shrinkage pool and communicates, the diameter of described round shrinkage pool is greater than the diameter of round tube hole, the axis of circle shrinkage pool, round tube hole is identical with the axis of threaded hole, after in the hexagon socket head cap screw precession threaded hole in circle shrinkage pool and round tube hole, regular triangular prism can be made to be locked in elongated slot.
The rapidoprint of described square rectangular, regular triangular prism and square baffle plate is aldary.
Advantage of the present invention is: squarely rectangularly easily can switch semicircle string slot quantity without the need to changing.
Accompanying drawing explanation
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the B-B cut-open view of concrete structure of the present invention.
Fig. 2 is the A-A cut-open view of concrete structure of the present invention.
Fig. 3 is the vertical view of concrete structure of the present invention.
In figure, (1) is elongated slot, and (2) are semicircle string slot, and (3) are regular triangular prism, and (4) are threaded hole, and (5) are hexagon socket head cap screw, and (6) are round tube hole, and (7) are circle shrinkage pool, and (8), for square rectangular, (9) are square baffle plate.
Embodiment
Below in conjunction with embodiment, the present invention is described further.
Embodiment: as Figure 1-3, manufacture and design capotasto on a kind of bass being convenient to switch semicircle string slot quantity, comprise square rectangular (8), the lower end of square rectangular (8) adopts strong viscose glue to be adhesively fixed to fix on the scroll head on the top of fingerboard, principal feature of the present invention is: it is equilateral triangle that the center line of the upper end edge length direction of square rectangular (8) is provided with square section, the elongated slot (1) of both ends open, adaptive regular triangular prism (3) is provided with in elongated slot (1), regular triangular prism (3) is left, the length of side of the equilateral triangle at right two ends is longer than the length of side of elongated slot (1) cross section equilateral triangle.
Three rectangle sides of regular triangular prism (3) are respectively equipped with 4 uniform semicircle string slots (2), 5 semicircle string slots (2) and 6 semicircle string slots (2) along its length.
Bottom in semicircle string slot (2) is higher than the upper end of square rectangular (8).
The left and right two ends of regular triangular prism (3) are respectively equipped with threaded hole (4), the left and right two ends of square rectangular (8) are respectively equipped with square baffle plate (9), the width dimensions of the width dimensions of square baffle plate (9) and height dimension rectangular with square (8) is respectively identical with height dimension, adopts strong viscose glue gluing fixing between square baffle plate (9) and square rectangular (8).
The round tube hole (6) that square baffle plate (9) is provided with round shrinkage pool (7) and communicates, the diameter of circle shrinkage pool (7) is greater than the diameter of round tube hole (6), the axis of circle shrinkage pool (7), round tube hole (6) is identical with the axis of threaded hole (4), to justify after in hexagon socket head cap screw (5) the precession threaded hole (4) in shrinkage pool (7) and round tube hole (6), regular triangular prism (3) can be made to be locked in elongated slot (1).
