Abstract

The utility model discloses a piano string fastening device which is a string clamping device arranged between a tuning page and a nut or additionally arranged on the nut. The piano string fastening device is characterized in that the string clamping device is composed of an upper clamp, a lower clamp and fastening screws, wherein strings are arranged between the upper clamp and the lower clamp, the upper clamp and the lower clamp are fastened through the fastening screws, and therefore fixedly clamping of the strings is achieved. The piano string fastening device has the advantages that the string clamping and fixing device which is simple in structure is additionally arranged under the premise of not changing the existing basic structure of a piano, the defect that the piano is apt to be out of tune is overcome, and intonation of the piano can be kept for a long time.

Description

A kind of piano string fastener

Technical field the utility model belongs to piano string fastening appliance technical field, relates to a kind of for to prevent that the string detonieren is used for clamping the piano string fastener of string.

The piano of background technology prior art normally relies on peg to set up the pitch of string, like carrying or use, the influence of humiture in addition for a long time, very easily causes the peg change, causes the string detonieren.Especially used the long period, the deformation of soundboard, Ma Qiao, iron skeleton and the change of peg are to cause that string is loosening, the piano detonieren, can not keep the principal element of accuracy in pitch for a long time.

The purpose of summary of the invention the utility model is to solve the loosening technical matters of prior art string, a kind of piano string fastener is provided, to overcome the deficiency of prior art.

To achieve these goals, the utility model piano string fastener, it is between peg and capotasto or the folder string device that on capotasto, installs additional; Said folder string device is made up of upper and lower folder and holding screw; String places between the upper and lower folder, and is after the temperament, by holding screw that upper and lower folder is fastening; Thereby accomplished fixing to clamp of string, fundamentally prevented to take place because of the peg change causes the phenomenon of piano detonieren.

The beneficial effect of the utility model is, under the prerequisite that does not change existing piano basic structure, installs string fastener simple in structure additional, overcome the defective of the easy detonieren of piano, can keep the accuracy in pitch of piano for a long time.

Description of drawings Fig. 1 is the structural representation that between peg and capotasto, adds clamping string device;

Fig. 2 is the structural representation that on capotasto, adds clamping string device.

Among the figure: press from both sides string bar 21,, press from both sides string bar 3, holding screw 4, string 5, peg 6, capotasto 7, iron skeleton down

Embodiment is as shown in Figure 1, and the utility model is the folder string device that between peg and capotasto, installs additional, and wherein upper and lower folder is last folder string bar 1 and following folder string bar 2, with the folder string device of holding screw 3 compositions; Under press from both sides and be drilled with a hole on the string bar 2, cooperates with holding screw 3 with last folder string bar 1, accomplish the task of the string 4 that is fixedly clamped, this embodiment is suitable in the installation of the middle and high range of sound.

Folder string device as shown in Figure 2, as on capotasto 6, to install additional, an end of string 4 is fixedly connected on the peg 5, and the lower end of peg 5 is fixedly mounted on capotasto 6 and the iron skeleton 7; Wherein upper and lower folder is last folder string bar 1 and capotasto 6, forms folder string device with holding screw 3; On capotasto 6, bore the silk hole, cooperate with holding screw 3 with last folder string bar 1, accomplish the task of the string 4 that is fixedly clamped, this embodiment is suitable for installing at bass area.

Because piano is divided into two kinds in vertical and bedroom, the difference of string row is bigger; With regard to same piano, nearly more than 200 of string, and diameter is different; Because high, medium and low sound is different; Each sound is made up of single, double joint, three strings respectively again, thus the folder string device of forming by upper and lower folder and holding screw to apply in a flexible way, must be different because of qin, because of the range of sound different; Adopt the folder of different geometries; Cooperate quantity different, the different holding screw of arranging, segmentation or the whole mode that clamps constitute folder string device.Attention: in working order down, the distance between the working surface of upper and lower folder is equal to or less than by the diameter of folder string; To be prerequisite not cause the string tension variation, confirm the position of folder string, reach the fixedly optimum efficiency of string.When piano tuning finishes, holding screw clamps whole strings one by one.In addition, folder string device defines the displacement of string to all directions in the folder string, so produce advantages of good positioning effect simultaneously, it is uniform and stable that string is arranged, and further stablized the performance of piano.Above-mentioned folder string device makes the string of clamping become the integral body that conditions each other, and can make piano after each temperament, and detonieren not for a long time keeps the accuracy in pitch of piano.The utility model need not change the structure of piano, can be widely used in various vertical, horizontal pianos.

Claims

1. piano string fastener; It is between peg and capotasto or the folder string device that on capotasto, installs additional; It is characterized in that said folder string device is made up of upper and lower folder and holding screw, string places between the upper and lower folder, and is by holding screw that upper and lower folder is fastening.
