Abstract
The utility model discloses a structure is prevented changeing by clarinet key post, including preventing changeing the device, it includes key support connnection portion and fixed part to prevent changeing the device, key support connnection portion sets up between key post and body, the fixed part passes through the bolt and is connected with the body, key support connnection portion is connected with the fixed part. The utility model discloses a preventing that the rotor passes through first ring and fixes the key post on the body with the second ring, playing dual fixed effect, it is rotatory, not hard up that the key post in which direction can not take place to the stability of key post and the performance quality of clarinet have been improved.
Description
Technical field
The utility model relates to musical instruments accessory technical field, particularly a kind of clarinet key post anti-rotation structure.
Background technology
Clarinet key post is mainly used in fixing key lever and button, and the key post of existing clarinet is generally threaded connection mode with body is fixedly connected with, namely bolt is set at key post root, body is provided with corresponding bolt hole, then direct key post is screwed on body, realize being fixedly connected with of key post and body, but there is a drawback in this mode: after clarinet uses a period of time, key post is very easy to loosen, and then cause that button is not in place, deviation appears in button, thus affect the playing quality of clarinet.
Utility model content
For solving the problem that existing clarinet key post easily loosens, the utility model discloses a kind of clarinet key post anti-rotation structure, comprise anti-rotation device, described anti-rotation device comprises key post connecting portion and fixed part, described key post connecting portion is arranged between key post and body, described fixed part is connected with body by bolt, and described key post connecting portion is connected with fixed part.
As further improvement of the utility model, described anti-rotation device is anti-rotation sheet, and described key post connecting portion is the first annulus, and described fixed part is the second annulus, and described first annulus and the second annulus connect and compose the figure of eight.
As further improvement of the utility model, described key post is fixedly connected with body through the first annulus, and described bolt is fixedly connected with body through the second annulus.
The beneficial effects of the utility model are:
Key post is fixed on body by the first annulus and the second annulus by anti-rotation sheet of the present utility model, play dual fixing effect, key post in which direction all can not rotate, loosen, thus improves the stability of key post and the playing quality of clarinet.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Fig. 3 is the structural representation of the utility model anti-rotation sheet.
Mark in figure: 1-anti-rotation sheet; 11-first annulus; 12-second annulus; 2-key post; 3-body; 4-bolt.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
As shown in Figure 1 to Figure 3, a kind of clarinet key post anti-rotation structure, comprise anti-rotation sheet 1, anti-rotation sheet 1 is provided with the first annulus 11 and the second annulus 12, first annulus 11 and the second annulus 12 connect and compose the figure of eight, key post 2 is fixedly connected with body 3 through the first annulus 11, and bolt 4 is fixedly connected with body 3 through the second annulus 12.
During use, first on body 3, offer the groove corresponding to anti-rotation sheet 1 shape, and in groove, offer 2 bolts hole, again anti-rotation sheet 1 is put into groove, then key post 2 is screwed in one of them bolt hole through the first annulus 11, and by bolt 4, second annulus 12 is screwed in another bolt hole, key post 2 is fixed on body.
By the way, play the effect of dual retainingf key post 2, key post 2 in which direction all can not rotate, loosen, thus improve the stability of key post 2 and the playing quality of clarinet.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
