Abstract

The utility model relates to a trombone piston structure in the instrument field. The utility model is characterized in that the radiuses of the two modulation pipes of the cylinder paw are equal, the radiuses of the inlet pipe and the outlet pipe of the cylinder paw are equal, and the proportion between the radiuses of the modulation pipe and the radiuses of the inlet pipe and the outlet pipe is from 1/1.10 to 1/1.15. The utility model with reasonable structure design uses cylinder paw with modulation pipes of smaller diameter instead of the cylinder paw with the same diameter with the inlet pipe and the outlet pipe, thereby, the veracity of the swing is effectively improved and the air stream of player is reduced. As a result, the applicable colony of trombone playing is increased and the routine cultural life of people is enriched.

Description

The trombone piston structure

Technical field

The utility model relates to the trombone in musical instrument field, especially the trombone piston structure.

Background technology

Trombone is a kind of Western blowing instrument that people prefer.The difference pronunciation of trombone is to realize by the size that the tolerance of air-flow in piston is distributed.The piston of existing trombone is for being provided with four isometrical cylinder claws with the footpath on piston, the connection draft tube is different with the cylinder claw of escape pipe with the function that the cylinder claw that is connected pitch pipe is produced, the tolerance adjustment of the cylinder claw of pitch pipe needs sensitive more, to realize pronouncing accurately musical note.Therefore because it is isometrical that the set cylinder claw of existing trombone is, it is bigger to need the player to play wind instruments tolerance.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of reasonable in design is provided, plays wind instruments trombone the piston structure narrow-minded and musical note of can realizing accurately pronouncing.

The utility model solves its technical matters and takes following technical scheme to realize:

This trombone piston structure, constitute by piston, cylinder claw, the cylinder claw is four and uniform with directly being packed on the piston, the draft tube and the escape pipe of cylinder claw are packed in lower part of piston, two pitch pipes of cylinder claw are packed in the top of piston, it is characterized in that: two pitch pipes of cylinder claw are isometrical, and the draft tube of cylinder claw and escape pipe are isometrical, and the caliber size of pitch pipe: the caliber size of draft tube and escape pipe=1: 1.10-1.15.

And, the caliber size φ 15.4mm of best pitch pipe; The optimum tube diameter size φ 17.0mm of draft tube and escape pipe.

Advantage of the present utility model and good effect are:

The utility model reasonable in design, employing substitutes and draft tube, the isometrical cylinder claw of escape pipe than the pitch pipe cylinder claw of minor diameter, can improve the accuracy of pronunciation musical note effectively, reduce player's the tolerance of playing wind instruments, improve the suitable colony that trombone is played, enrich people's daily culture life.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but is not limited to the content that present embodiment is narrated.

This trombone piston structure is made of piston 3 and cylinder claw, and the cylinder claw is four and uniformly is packed on the piston with the footpath that the draft tube of cylinder claw 2 is packed in lower part of piston with escape pipe 5, and the two is coaxial state after extending.Two

pitch pipes

1,4 of cylinder claw are packed in the top of piston, in order to adapt to the rational deployment of pitch pipe, one of two pitch pipes of general cylinder claw are skewed extension (as the pitch pipe 4 of the cylinder claw in the present embodiment), two pitch pipes of cylinder claw are isometrical, the draft tube of cylinder claw and escape pipe are isometrical, and the caliber size of pitch pipe: the caliber size of draft tube and escape pipe=1: 1.10-1.15.

The caliber size of the best pitch pipe in this present embodiment: φ 15.4mm; The optimum tube diameter size of draft tube and escape pipe: φ 17.0mm.

Claims

1. trombone piston structure, constitute by piston, cylinder claw, the cylinder claw is four and uniform with directly being packed on the piston, the draft tube and the escape pipe of cylinder claw are packed in lower part of piston, two pitch pipes of cylinder claw are packed in the top of piston, it is characterized in that: two pitch pipes of cylinder claw are isometrical, and the draft tube of cylinder claw and escape pipe are isometrical, and the caliber size of pitch pipe: the caliber size of draft tube and escape pipe=1: 1.10-1.15.

2. trombone piston structure according to claim 1 is characterized in that: the caliber size φ 15.4mm of best pitch pipe; The optimum tube diameter size φ 17.0mm of draft tube and escape pipe.
