Description

Wind instrument's wooden receiver

Technical Field

The utility model relates to a wind instrument packing carton specifically is a wind instrument's wooden lid of accomodating.

Background

Wind instruments in China are popular, and are still the main instruments in civilian weddings and funerals and folk custom festivals. Bamboo is inexplicable with Chinese wind instruments, and the best raw material for manufacturing national musical instruments such as flute, cucurbit flute, bawu, flute, sheng and the like is still bamboo, mainly because the bamboo has the best sound effect. The Bawu is divided into three types, namely high pitch, middle pitch and low pitch Bawu because the bamboo sound tube is different in length and thickness. The tube body is blown transversely when it is thick and long, and blown vertically when it is thin and short. The great sound chamber of diameter is equipped with on upper portion to the vertical blowing bawu usually, and for convenient to carry, vertical blowing bawu sound chamber and sound pipe design are for dismantling the connection, just with the sound chamber and the sound pipe separation of bawu when not using, put into the storage compartment of bawu receiver respectively in, because the sound chamber diameter is great, the receiver is thicker, and it is inconvenient to carry, and the outward appearance is not pleasing to the eye. The inventor has applied for the name "receiver of vertical blowing bawu" application number is 2020204946259's patent technical scheme, and this technical scheme makes the receiver volume of vertical blowing bawu less, convenient to carry, and the appearance is pleasing to the eye. But in the production and use process, the periphery of the upper plane of the box cover is provided with the chamfer with the same width, the appearance is regular and beautiful, the box cover and the box body are easy to warp upwards at two ends, and the product percent of pass is low by 10-20%.

Disclosure of Invention

The utility model discloses to "a vertically blow Bawu's receiver" application number is 2020204946259 patent technical scheme lid upper plane periphery makes the constant width chamfer, lid and the equal easy problem of warping up deformation, the qualification rate low of box body, provide a new technical scheme of blowpipe musical instrument's wooden receiver.

The technical scheme of the utility model is that: the utility model provides a blowpipe musical instrument's wooden receiver is equipped with storage compartment on the rectangle box body, lid below indent, is the limit of evagination all around, and the edge all around on the lid plane all is equipped with chamfer, its characterized in that: the short edges of the periphery of the upper plane of the box cover and the lower plane of the box body are provided with inclined short chamfers, and the long edges of the box cover are provided with inclined long chamfers.

The inclined short chamfer angle is as follows: the outer ends of the two short chamfers are wide, and the inner ends of the short chamfers are gradually narrowed; the inclined long chamfer is composed of two symmetrical long chamfers, the outer ends of the two long chamfers are wide, and the inner ends of the long chamfers are gradually narrowed; the inclined short chamfer angle is as follows: each short chamfer is symmetrically inclined towards two sides by an angle B, B = 10-25 degrees along the central line of the length direction of the storage box, and then is inclined by an angle c, c = 10-25 degrees with the horizontal plane of the box body, and the inclined long chamfers are as follows: each long chamfer angle is inclined at an angle a of 2-8 degrees towards two sides symmetrically along the central line of the box cover in the width direction, and then is inclined at an angle c of 10-25 degrees with the horizontal plane of the box body.

The aspect ratio of receiver be greater than 3:1

The storage boxes of slender wind instruments such as a bawu, a flute, a xiao and the like are all flat long boxes, the storage box of the prior vertical blowing bawu is made of high-quality wood, the storage box of the vertical blowing bawu is in a flat and long rectangular shape, and the box body is usually made in the length direction of the wood. The inventor's prior art patent is also a flat elongated box with an aspect ratio of about 4:1, the peripheral 15-20 degrees chamfers of aequilate that make in plane on the lid, see fig. 4, the receiver appearance of making is pleasing to the eye regular, but the receiver of making is placed a period of time after, the receiver both ends warp the deformation upwards very easily, the low 10% -20% that causes of percent of pass of receiver. Through the repetition test, according to the utility model discloses a receiver that the scheme was made, the chamfer on every limit is by the unequal wide two sections of constituteing of symmetry gradual change, the establishment at both ends of chamfer outer end broad, the narrower establishment in the middle of chamfer inner, the chamfer on lid and the box body is the unequal wide chamfer of 8 symmetry gradual changes for stress on lid and the box body obtains balancing, lid and box body are placed for a long time and are warp again, the qualification rate of receiver rises to 90% -95%. According to the utility model discloses a by 8 sections the unequal width chamfers of symmetry gradual change have formed graceful lines on lid and the box body of technical scheme preparation, do the utility model discloses an outward appearance hyperchromia. The utility model discloses be particularly suitable for the wooden receiver of long and thin musical instrument, can extensively be applicable to the wooden receiver of crossblow bawu or vertical blowing bawu, also can be applicable to the wooden receiver of long and thin wind pipe musical instrument such as flute, xiao. The utility model discloses think about ingenious, the preparation is convenient, and the appearance is pleasing to the eye, and receiver stable in quality indeformable has improved the product percent of pass greatly, is a novel blowpipe musical instrument's wooden lid of accomodating.
