Abstract
The utility model relates to a worm and gear structure type drum set muffler. The worm and gear structure type drum set muffler comprises a gear and a worm. An end of the worm is fixedly connected with one end of a triangular connecting rod. The other end of the triangular connecting rod is provided with a muffling pad. With the worm and gear structure, the problem that the previous muffling device influences the sound quality is solved, the overall structure is simple, and the worm and gear structure type drum set muffler is practical.
Description
Technical field
The utility model relates to a kind of percussion instrument servicing unit, is specifically related to a kind of noise-abatement equipment of frame drum.
Background technology
Frame drum is a kind of Western percussion instrument of circle, and sound is very big when beaing performance, but student and the drummer this very big sound when practising will produce the problem that disturbs residents; A lot of for this reason drummers are rubber blanket on the drum head upper berth; Sound has obviously reduced like this, but this can influence in one's hands having an effect, and feels also just flat; Do not have feel that the effect of drummer exercise is had a greatly reduced quality, the raising of technical ability is brought certain resistance.
The frame drum that a kind of embedded with drum pad capable of adjusting volume is arranged in the market, its drum pad contacts with drum head when exercise.Reach the purpose of noise reduction, its drum pad moves down with drum head and breaks away from when formal performance, but the drum head normal articulation; The drum pad was parallel all the time with drum head when the shortcoming of this device was the drum head normal articulation; Drum pad retaining hinders sound wave and fully resonates in the middle of drum head up and down, influences tonequality.So making a kind of frame drum quieter that neither disturbs residents and do not influence practice effect is urgent problem.
Summary of the invention
Goal of the invention: the purpose of the utility model is in order to overcome deficiency of the prior art, to provide a kind of simple in structure, neither disturbs residents and does not influence the worm and gear structural formula frame drum exhaust box of performance tonequality.
Technical scheme: in order to solve the problems of the technologies described above; The described worm and gear structural formula of the utility model frame drum exhaust box; It comprises worm and worm wheel, is fixedly connected with square connecting link one end on one on said worm gear, is provided with silencing pad at the said square connecting link other end.
Said worm screw rotates.
Said square connecting link and silencing pad move up and down through worm gear.
Said worm and gear routing motion moves up and down thereby drive quieter, when need not performing or practise at ordinary times; Can be adjusted to horizontal level to quieter, fit, protection frame drum face with the drum face; When needs exercise or performance, need only rotary worm slightly, make quieter move toward oblique below; Rather than can only do level as some former quieter and move up and down, thereby influence performance tonequality.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model adopts the worm and gear structure, solved the problem that former quieter influences tonequality, and one-piece construction is fairly simple, and is practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein:
1, worm screw; 2, worm gear; 3, square connecting link; 4, silencing pad.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, the described worm and gear structural formula of the utility model frame drum exhaust box, it comprises worm screw 1 and worm gear 2, is fixedly connected with square connecting link 3 one ends on 2 one on said worm gear, is provided with silencing pad 4 at said square connecting link 3 other ends; Said worm screw 1 rotates; Said square connecting link 3 moves up and down through worm gear 2 with silencing pad 4.The utility model adopts the worm and gear structure, solved the problem that quieter influences tonequality, and one-piece construction is fairly simple, and is practical.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
