Abstract

Mouthpiece is adjusted the utility model discloses a kind of saxophone and enters tolerance structure, is against on the inner cavity upper wall of flute head including flute head and the shaft being rotatably connected between the front and rear wall of flute head inner cavity, the shaft.The shaft is fixed with the regulating mechanism for changing flute head inner cavity air inlet section by rotation.When adjusting into tolerance, then loosening nut rotates spin-block, spin-block drives shaft rotation, thus promote flapper, the direction rotation of the inner cavity lower wall of Xiang Ditou, in this way, the intracavity section of flute head reduces because of the blocking of baffle, the arrival end blow gas pressure of such flute head increases, air inflow reduces, and entering tolerance maximum when initial, when initial in this way, flute head opening is larger, accomplish that adjustable range is bigger, tightening nut after regulating.The baffle of rotation can scrape rubber membrane, to jack up rubber membrane, in downwardly convex arc-shaped, such resistance also avoids the gas blown into from flowing to the interior of baffle and flute head with regard to smaller.

Description

A kind of saxophone adjusts mouthpiece and enters tolerance structure

Technical field

Enter tolerance the utility model relates to saxophone mouthpiece and adjust field, specially a kind of saxophone adjusts mouthpiece and enters Tolerance structure.

Background technique

We are familiar with saxophone, are useful in many play.Saxophone is blown by flute head, subsequently into tube body into Row pronunciation, the size of flute head opening determine to be open bigger into tolerance, and air inlet is more convenient, play wind instruments it is more laborsaving, still, excessive energy It will affect pronunciation, and the flute head of the saxophone in market is open substantially fixed, air inflow is fixed, it is difficult to adjust, for this reason, it may be necessary to It is a kind of to adjust into tolerance.

Utility model content

Mouthpiece is adjusted the purpose of this utility model is to provide a kind of saxophone and enters tolerance structure, to solve above-mentioned background The problem of being proposed in technology.

To achieve the above object, the utility model provides the following technical solutions: a kind of saxophone adjusts mouthpiece and enters tolerance Structure is against on the inner cavity of flute head including flute head and the shaft being rotatably connected between the front and rear wall of flute head inner cavity, the shaft On wall；

The shaft is fixed with the regulating mechanism for changing flute head inner cavity air inlet section by rotation.

Preferably, the regulating mechanism include be fixed in shaft along in the horizontally disposed abutting flute head of airintake direction The baffle of chamber front and rear wall, and the both ends of shaft stretch out flute head and are provided with retention mechanism.

Preferably, the retention mechanism includes the spin-block for being fixed on shaft one end, and the other end of shaft is connected with abutting The secure component of flute head.

Preferably, the secure component is nut.

It preferably, further include the elasticity for slowing down air intake resistance on the downside of baffle and eliminating the air inlet noise that baffle generates Rubber membrane, the rubber membrane are fixedly connected along the both ends of flute head airintake direction with flute head.

Compared with prior art, the utility model has the beneficial effects that

1, when adjusting into tolerance, then loosening nut rotates spin-block, spin-block drives shaft rotation, so that baffle be promoted to turn It is dynamic, the direction rotation of the inner cavity lower wall of Xiang Ditou, in this way, the intracavity section of flute head reduces, such flute because of the blocking of baffle The arrival end blow gas pressure of head increases, and air inflow reduces, and it is initial when enter tolerance maximum, when initial in this way, flute head opening is big by one A bit, accomplish that adjustable range is bigger, tightening nut after regulating；

2, the baffle rotated can scrape rubber membrane, to jack up rubber membrane, in downwardly convex arc-shaped, such resistance is just It is smaller, it also avoids the gas blown into from flowing between baffle and the internal chamber wall of flute head, avoids generating echo, influence blowing for saxophone Play, accomplish it is round and smooth enter gas, more smooth nature.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to Fig. 1 to 3, the utility model, which provides a kind of saxophone and adjusts mouthpiece, enters tolerance structure technology scheme: one Kind saxophone adjusts mouthpiece and enters tolerance structure, including flute head 1 and turn being rotatably connected between 1 inner cavity front and rear wall of flute head Axis 2, shaft 2 are against on the inner cavity upper wall of flute head 1.

Shaft 2 is fixed with the regulating mechanism for changing 1 inner cavity air inlet section of flute head by rotation, and regulating mechanism includes being fixed on The baffle 21 along the horizontally disposed abutting 1 inner cavity front and rear wall of flute head of airintake direction in shaft 2, and the both ends of shaft 2 are stretched out Flute head 1 is provided with retention mechanism, and shaft 2 rotates, and baffle 21 is driven to rotate, to change air inlet section, changes air inflow, fastening Mechanism includes the spin-block 22 for being fixed on 2 one end of shaft, and the other end of shaft 2 is connected with the secure component for pushing against flute head 1, passes through Secure component limits shaft 2 and rotates, and secure component is nut 23, pushes against flute head 1, is fixed, and further includes being located under baffle 21 Side slow down air intake resistance and eliminate baffle 21 generate air inlet noise elasticity rubber membrane 24, rubber membrane 24 along flute head 1 into The both ends in gas direction are fixedly connected with flute head 1, and the baffle 21 of rotation jacks up rubber membrane 24, are made an uproar so that baffle 21 be avoided to tilt generation The rubber membrane 24 of sound, jack-up is arc-shaped.

When adjusting into tolerance, then loosening nut 23 rotates spin-block 22, spin-block 22 drives shaft 2 to rotate, to promote to keep off Plate 21 rotates, the direction rotation of the inner cavity lower wall of Xiang Ditou 1, tightening nut 23 after regulating.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
