Abstract

The utility model relates to a violin family end pin with an enlarged perspective function. The violin family end pin is made of acrylic and formed by a pin body, a pin cap and baffle rings, wherein the pin body, the pin cap and the baffle rings are in a cylindrical shape. The pin cap is coaxially manufactured at the upper end of the pin body, the baffle rings are coaxially manufactured on the pin body under the pin cap at intervals, a groove is formed on the pin body between the pin cap and the baffle rings, an upper arc face is manufactured on the upper end face of the pin cap, and a lower arc face is manufactured on the lower end face of the pin body. The end pin is made of acrylic materials which have high definition perspective performance, so that placing conditions of a sound pin can be visually inspected, when the position of the sound pin needs adjusting, only strings of the violin family needs loosening without the need to dismantle the end pin, and the adjustment and installation can be achieved through the end pin. When the position of the end pin is ensured to be installed in place, the strings of the violins can be tightened again, so that troubles are reduced, and a defect that damage of the end pin caused by frequent dismantling of the end pin is avoided.

Description

Violin stern post with magnification fluoroscopy function

Technical field

The utility model belongs to the musical instrument field, relates to violin and comprises violin, viola etc., especially a kind of violin stern post with magnification fluoroscopy function.

Background technology

Our violin seen comprises violin, viola at present, and its stern post (also being the tail button) is that characteristics are wooden hard with ebony or the wooden one-tenth of jujube mostly, and color and other accessories are unified, and major function is a fixing chord-drawing plate on body.In assembling, debugging and the use of violin, because being the solid wood material, makes stern post, in case after being in place, just can't see through the installation site situation that sound column is checked in the stern post hole again.Although sound column just is in place after closing qin; And through the stern post hole sound column being carried out debugging; But in order to obtain best sound effect; Need adjustment repeatedly in the initial accordatura of the position of sound column after string assembling, the tuning, and in the future because the variation of humidity or use in the qin sound takes place variation sound column is debugged, is changed, also need carry out trickle adjustment to sound column.And when the tuning post, do not see through the stern post hole and observe accurate verticality and the faying face that sound column and surface backplate just can not be detected in the position of sound column, particularly to the beginner.So in order to realize best tonequality, the best way is that string is loosened and takes off the position that stern post is observed sound column when adjusting sound column at every turn, all can have influence on the qin sound because the trickle crooked or faying face of sound column is unstable.And existing version causes and must unload stern post at every turn and adjust sound column, and is pretty troublesome, very loaded down with trivial details, and damage the stern post hole easily.

Summary of the invention

The purpose of the utility model is to overcome the prior art deficiency, provides a kind of and can conveniently observe, adjust the violin stern post with magnification fluoroscopy function of sound column installation situation.

The technical scheme that the utility model adopts is:

A kind of violin stern post with magnification fluoroscopy function; The stern post of being made by acrylic is made up of columniform shaft, cap, baffle ring; The coaxial cap of processing in the upper end of shaft, coaxial spaced is shaped on baffle ring on the shaft below the cap, and the shaft between cap and this baffle ring forms groove; It is characterized in that: process cambered surface in the upper surface of cap, process lower camber side in the lower surface of shaft.

And the last cambered surface of said cap is that coaxial mirror image is symmetrical set with the lower camber side of shaft lower end.

The utility model advantage and good effect are:

1, this stern post adopts acrylic material to make, and has the perspective performance of high definition, the situation of laying that can the macroscopic examination sound column; Only need when needing to regulate the sound column position string Panasonic; Will not unload by stern post, through stern post adjustment is installed and gets final product, wait to be sure of again string to be tightened after the sound column position is in place; So both reduced trouble, and avoided stern post again because of often unloading the drawback of damaging the stern post hole.

2, this stern post end face and lower surface is all processed coaxial cambered surface above that, forms convex lens, and each structure and parts installation situation in can magnification fluoroscopy qin case have strengthened observing effect, have improved the assembling and setting level of violin.

3, this stern post one-piece construction is simple, and design science is reasonable, and is easy to use, improved the acoustical quality of violin, also can improve the efficient of tuning simultaneously.

Fig. 1 is the structural front view of the utility model; ,

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that the A-A of Fig. 2 is to cross-sectional view.

Embodiment:

Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.

A kind of violin stern post with magnification fluoroscopy function, the material selection acrylic of whole stern post is made, and has whole penetrating effect.Stern post is made up of columniform shaft 5, cap 2, baffle ring 4, and the coaxial cap of processing in the upper end of shaft is processed cambered surface 1 in the upper surface of cap; Coaxial spaced is shaped on baffle ring on the shaft below the cap, and the shaft between cap and this baffle ring forms groove 3, is used to fasten chord-drawing plate; Process lower camber side 6 in the lower surface of shaft, the last cambered surface of cap is that coaxial mirror image is symmetrical set with the lower camber side of shaft lower end, forms the convex lens with enlarging function thus.

Claims

1. violin stern post with magnification fluoroscopy function; The stern post of being made by acrylic is made up of columniform shaft, cap, baffle ring; The coaxial cap of processing in the upper end of shaft, coaxial spaced is shaped on baffle ring on the shaft below the cap, and the shaft between cap and this baffle ring forms groove; It is characterized in that: process cambered surface in the upper surface of cap, process lower camber side in the lower surface of shaft.

2. the violin stern post with magnification fluoroscopy function according to claim 1 is characterized in that: the last cambered surface of said cap is that coaxial mirror image is symmetrical set with the lower camber side of shaft lower end.
