Abstract
The utility model discloses a novel dulcimer numeral structure. The structure comprises a positioning strip and two supporting posts, wherein the bottom end of each supporting post is fixed on the positioning strip. The structure is characterized in that: an included angle between the annual ring of the wood of the positioning strip and the bottom line of the positioning strip is in a range of 0 to 30 degrees; and the included angle between the annual ring of the wood of the supporting posts and the bottom line of the positioning strip is in a range of 60 to 90 degrees. Compared with the prior art, the structure has the beneficial effects that: due to the improvement of the numeral structure, the deformation resistance of the numeral structure is greatly improved, a numeral is not easy to deform and damage, and the service life of the numeral is greatly prolonged.
Description
Technical field
The utility model relates to a kind of dulcimer, more specifically to a kind of novel dulcimer numeral structure.
Background technology
Existing dulcimer, its numeral structure adopts a plank to make usually, numeral comprises positioning strip and at least two support columns, each support column is located on the positioning strip, the top of each support column is equipped with cushion block, in order to alleviate the weight of numeral, improve the resonance performance of numeral, on positioning strip, also have a plurality of through holes.
Because the annual rings of timber of plank is parallel with positioning strip (base of positioning strip), and the positioning strip of numeral and support column be made into integration, so the annual rings of timber of positioning strip and support column all is parallel to each other.Like this, the player is when knocking string, string can apply acting force to support column, this acting force can resolve into parallel action power parallel with the direction of annual rings of timber and the vertical vertical with the direction of annual rings of timber, especially be positioned at foremost the support column with rearmost end, the parallel action power maximum that is subjected to.
Because being positioned at the part of annual rings of timber both sides, plank is equivalent to two different structural sheets, and annual rings of timber is the separatrix of two structural sheets, under the continuous action of bigger parallel action power, it is different big to be positioned at the power that the part of each annual rings of timber both sides is subjected to, therefore through after using for a long time, plank disconnects in the annual rings of timber position easily, causes support column distortion, the damage of numeral.
The annual dulcimer that this structure of a large amount of employings is all arranged, its numeral deforms, damages, and some dulcimer even numeral damage suddenly in use cause playing and have to interrupt, and bring tremendous loss and bad influence to the player.Therefore existing this numeral structure has influenced the serviceable life of dulcimer greatly, causes the numeral needs of dulcimer often to be changed.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of novel dulcimer numeral structure is provided, and can prevent effectively that numeral from deforming, damaging, and significantly prolongs the life-span of numeral, and the technical scheme of employing is as follows:
A kind of novel dulcimer numeral structure of the present utility model, comprise positioning strip and at least two support columns, each support column bottom is fixed on the positioning strip, and the top of each support column is equipped with cushion block, it is characterized in that: the angular range on the annual rings of timber of described positioning strip and the base of positioning strip is the 0-30 degree, and the angular range on the annual rings of timber of described each support column and the base of positioning strip is the 60-90 degree.
More excellent scheme, the angular range on the annual rings of timber of described positioning strip and the base of positioning strip is the 0-15 degree, the angular range on the annual rings of timber of described each support column and the base of positioning strip is the 80-90 degree.
Preferred scheme, the angular range on the annual rings of timber of described positioning strip and the base of positioning strip is the 0-5 degree, the angular range on the annual rings of timber of described each support column and the base of positioning strip is the 85-90 degree.
The scheme of selecting most, the annual rings of timber of described positioning strip is parallel with the base of positioning strip, and the annual rings of timber of described each support column is vertical with the base of positioning strip.Because the annual rings of timber of each support column is vertical with the base of positioning strip, therefore parallel with the base of positioning strip parallel action power is vertical with annual rings of timber, so the power that the part of each annual rings of timber both sides of support column is subjected to is equally big, can not cause support column to disconnect in the annual rings of timber position.
In order to alleviate the weight of numeral, improve the resonance performance of numeral, also have a plurality of through holes on the described positioning strip.
The utility model beneficial effect against existing technologies is, because the numeral structure is improved, therefore significantly promoted the non-deformability of numeral structure, makes numeral be not easy distortion, damage, and significantly prolonged the life-span of numeral.

Embodiment
Embodiment 1
As shown in Figure 2, a kind of novel dulcimer numeral structure in the present embodiment, comprise positioning strip 1 and five support columns 2, each support column 2 bottom is fixed on the positioning strip 1, and the top of each support column 2 is equipped with cushion block 4, first annual rings of timber 101 of described positioning strip 1 is 0 degree with the angle on the base 102 of positioning strip, and second annual rings of timber 201 of described each support column 2 is 90 degree with the angle on the base 102 of positioning strip 1.
Because second annual rings of timber 201 of each support column 2 is vertical with the base 102 of positioning strip 1, therefore parallel with the base 102 of positioning strip 1 parallel action power is vertical with second annual rings of timber 201, so the power that the part of support column 2 each second annual rings of timber, 201 both sides is subjected to is equally big, can not cause support column 2 to disconnect in second annual rings of timber, 201 positions.
In order to alleviate the weight of numeral, improve the resonance performance of numeral, also have a plurality of through holes 3 on the described positioning strip 1.
The non-deformability of this numeral is best, but the manufacturing cost of this numeral is very high, because will find very difficulty of such plank, so the manufacturing cost height.
Embodiment 2
The difference of present embodiment and embodiment 1 is:
First annual rings of timber 101 of described positioning strip 1 is 30 degree with the angle on the base 102 of positioning strip 1, and second annual rings of timber 201 of described each support column 2 is 60 degree with the angle on the base 102 of positioning strip 1.
The selection ratio of this numeral is easier to, but the non-deformability of numeral is relatively poor.
The difference of present embodiment and embodiment 1 is:
First annual rings of timber 101 of described positioning strip 1 is 15 degree with the angle on the base 102 of positioning strip 1, and second annual rings of timber 201 of described each support column 2 is 80 degree with the angle on the base 102 of positioning strip 1.The selection of this numeral is difficulty relatively, but the non-deformability of numeral is better.

First annual rings of timber 101 of described positioning strip 1 is 5 degree with the angle on the base 102 of positioning strip 1, and second annual rings of timber 201 of described each support column 2 is 85 degree with the angle on the base 102 of positioning strip 1.
The selection of this numeral is not easy, but the non-deformability of numeral is fine.
Embodiment 5
The difference of present embodiment and embodiment 1 is:
First annual rings of timber 101 of described positioning strip 1 is 3 degree with the angle on the base 102 of positioning strip 1, and second annual rings of timber 201 of described each support column 2 is 88 degree with the angle on the base 102 of positioning strip 1.
The selection of this numeral is very difficult, but the non-deformability of numeral is very good.
The producer can select suitable numeral structure, to adapt to consumer demand according to consumer's actual needs.
