Description

A kind of spike bar violoncello easy to adjust

[technical field]

The utility model belongs to musical instrument and makes the field, relates generally to a kind of spike bar violoncello easy to adjust.

[background technology]

All kinds of violoncello spike bars that generally use at present be produced complete after, spike bar surface is without any length mark.The spike bar is to be placed in the middle of the tail button of violoncello lower end, and it is external that this end of bung flange and rubber tip is exposed at qin, and this end of pin-and-hole is hidden in the qin body.A knob is arranged on the tail button, it is unclamped, the spike bar can be pulled out to qin is external, screw again knob and withstand from the side the spike bar, with locking spike bar.The violoncellist needs to adjust the length that the spike bar exposes the qin body before performance, allows qin and health keep suitable angle, then strikes up again.But the player adjusts the protruded length of spike bar often with range estimation and experience, and each the performance goes to past repeatedly debugging the spike bar could be fixed on relatively suitable state several times, relatively expends time in, and affects player's performance.

[utility model content]

The purpose of this utility model solves the problems of the prior art exactly, a kind of spike bar violoncello easy to adjust is proposed, the player can be settled at one go when adjusting spike bar protruded length, be convenient to the player and accurately control spike bar protruded length and qin height, bring convenience for player's performance, simultaneously also can make things convenient for the people such as teacher and the head of a family to distinguish player's playing state, in order in time make corresponding guidance or help.

For achieving the above object, the utility model proposes a kind of spike bar violoncello easy to adjust, comprise qin body and spike bar, on the described qin body tail button is installed, the upper end of described spike bar has pin-and-hole, the lower end of spike bar is equipped with rubber tip and bung flange, and the upper end of described spike bar is passed the tail button and extend in the qin body, and some scales and some readings are carved with in the surface of described spike bar.

As preferably, also comprise knob, described knob is installed on the tail button, but rigid staybolt foot lever when knob screws, the spike bar was removable when knob unscrewed, and is simple in structure, and adjusting and location are convenient.

As preferably, described scale and reading arrange rationally between the bung flange and pin-and-hole on the spike bar.

As preferably, the equal parallel equidistant setting of all scales, the axis of scale and spike bar is perpendicular, and reading increases to the upper end successively from the lower end of spike bar, handling ease reads conveniently, and is simple in structure, distinguishes easily, reasonable in design, meet and read custom, easy to use.

The beneficial effects of the utility model: the utility model has changed the spike bar surface state of conventional violoncello spike bar, so that the player can read the scale on it more intuitively, thereby can when adjusting spike bar protruded length, settle at one go, saved the repeatedly trouble of debugging, do not affect overall performance and the use of spike bar, can not cause harmful effect to the overall appearance of spike bar and violoncello, be convenient to the player and accurately control spike bar protruded length and qin height, bring convenience for player's performance, simultaneously also make things convenient for the people such as teacher and the head of a family to distinguish player's playing state, in order in time make corresponding guidance or help, the utility model is rational in infrastructure, simply, ingenious, handling ease, with low cost, it is rapid to be convenient to the user, regulate exactly the protruded length of violoncello spike bar, can be widely used on the violoncello of all kinds and model.

Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
