Description

A kind of light-duty cornet

Technical field

The utility model belongs to wind instrument field, is related to a kind of light-duty cornet.

Background technology

Existing cornet is metal material, very heavy, not readily portable, is also not easy to play, expends player a large amount of Muscle power, and use light material, the cornet as made from plastic material, then the characteristic because of material in itself, being typically considered to can not Reach the performance audio of traditional copper cornet.In addition, not only material cost is higher for copper cornet, and costly, and it is easily rotten Erosion, intraoral aqueous vapor enters membership corrosion tubular body during performance, so as to influence to use；Simultaneously copper rich glug number is needed through conventional Number oil is maintained, and is otherwise easily got rusty, it not only needs the number of purchasing oil to pay financial cost in maintenance, but also to expend guarantor Foster cost of labor.

The content of the invention

The technical problem that the utility model is solved is to provide a kind of manufacture craft simply, rational in infrastructure, and tone color is graceful, New cornet easy to use.

The technical scheme that the utility model is used by solution its technical problem is：

A kind of light-duty cornet, including main tube body, piston apparatus and looped pipeline, the inlet end setting number of the main tube body Mouth, outlet side is horn mouth, and main tube body also includes four tuning pipeline sections, respectively the first big syphon, the second big syphon, first Small bend pipe, the second small bend pipe, are straight tube between number mouth and the first big syphon, also have one section of whistle pipe number between mouth and straight tube, horn mouth with There is sound tube between second big syphon, support member is set between straight tube and sound tube part, the main tube body is generally spliced Plastics integrative-structure；The piston apparatus is made up of three piston boit connections, and the structure of three piston boits is consistent, all including modeling Expect piston, plastic key, piston only, plastic roof and plastic bottom cover composition, the plastic roof is located at plastic key Between piston only, and cover on piston only, the plastic bottom cover is covered in the bottom of plastic piston shell, and plastics are pressed The pole of key lower end is connected with piston only upper-end contact；Passage, each piston boit are all offered on three piston boits On all open up two looped pipeline blow vents, each looped pipeline two ends are bonded at the two looped pipeline blow vents, therefore the piston apparatus On be connected with 3 looped pipelines, respectively the first looped pipeline, the second looped pipeline and the 3rd looped pipeline, two pistons of the piston apparatus both sides There is the supervisor's passage being connected with main tube body on post respectively.

Further, setting looped pipeline water valve on supervisor's water valve, the 3rd looped pipeline is provided with first big syphon.

Further, the support member is plastics sheet structure and two ends are bonded on straight tube and sound tube respectively, is supported Part has two, positioned at piston apparatus both sides.

Further, the whistle pipe be uniform wall thickness polymeric material molding, and the whistle pipe body include to connect First conical pipe of number mouth, the second conical pipe, and it is connected to the first straight tube and the second straight tube therebetween, first cone Shape pipe and the second conical pipe are oppositely arranged by the small side in aperture each other, and first straight tube is along the first taper pore Straight tube formed by the small side in footpath is horizontal-extending, second straight tube is along the small side level in the second conical pipe aperture Straight tube formed by extension, the aperture of second straight tube is less than the aperture of first straight tube and therefore in the outer wall of two straight tubes Single stair-stepping outer wall stage portion and inwall stage portion have been staggered to form respectively with internal face connection end.

The utility model is had an advantageous effect in that compared with prior art：

Compared with prior art, cornet body of the present utility model is made of integrally moulded, simple in construction, and respectively It need to be only bonded between part by glue, easy to make, light weight, cost are low, and plastics non-corrosive, anticorrosive, guarantor Support and be also very easy to, need to only be rinsed with clear water, even if using also as snug as a bug in a rug, and right under cold or hot weather Deep improvement has been carried out in piston apparatus, the structure of original copper piston bush has been abandoned completely, many redundancy portions are eliminated Mechanical engagement between part, each part is more directly effectively, simple smooth, manufactures also simpler convenience, substantially reduces Cost is manufactured, especially whistle tubular construction is improved, the polymeric material wind instrument such as plastics sound hair is overcome completely Tapering this defect of shortage texture, the sound sent is simple and honest and deep, so more changeable, abundant melody, practicality can be played out It is stronger.

Embodiment

In order that obtaining those skilled in the art further understands feature of the present utility model and technology contents, according to attached Figure is made described further below to the utility model.

As illustrated in fig. 1 and 2, the utility model provides a kind of light-duty cornet, including main tube body, piston apparatus and looped pipeline, The inlet end setting mouth 2 of the main tube body, outlet side is horn mouth 3, and main tube body also includes four tuning pipeline sections, respectively For the first big syphon 6, the second big syphon 5, the first small bend pipe 8, the second small bend pipe 7, supervisor is provided with first big syphon 6 Be straight tube 14 between water valve 13, the big syphon of number mouth 2 and first, also have one section of whistle pipe 1 number between mouth and straight tube, horn mouth with it is second largest curved Have sound tube 15 between pipe, between straight tube 14 and sound tube 15 set support member 4, the support member 4 be plastics sheet structure and Two ends are bonded on straight tube 14 and sound tube 15 respectively, and support member has two, positioned at the both sides of piston apparatus 16, supervisor's pipe The plastics integrative-structure that body is generally spliced.

As shown in figure 3, described piston apparatus 16 is made up of three piston boit connections, the structure of three piston boits is consistent, All constituted including plastic piston shell 21, plastic key 17, piston only 24, plastic roof 18 and plastic bottom cover 19, the work There is inside and outside piston bush sliding engagement with one another inside shell 21 beyond the Great Wall, the plastic roof is located at plastic key 17 and piston only Between 24, and cover in piston only upper end, the plastic bottom cover 19 is covered in the bottom of plastic piston shell, the piston sheet Body 24 includes piston only shell, piston head, connecting rod, spring, spring top stator, spring bottom stator, the piston only Shell is be bonded with plastic piston shell to form integrative-structure, and the piston head is metal material, and the connecting rod is plastic material, even Extension bar is fixedly linked with piston head, and spring bottom stator, spring and spring top stator are socketed in the connecting rod successively On, the pole 20 of plastic key lower end is connected with piston only upper-end contact；Passage is all offered on three piston boits, Two looped pipeline blow vents 22 are opened up on each piston boit, each looped pipeline two ends are bonded at the two looped pipeline blow vents, therefore 3 looped pipelines, respectively the first looped pipeline 9, the second looped pipeline 10 and the 3rd looped pipeline 11, the 3rd pair are connected with the piston apparatus Set on pipe on looped pipeline water valve 12, two piston boits of the piston apparatus both sides has the supervisor being connected with main tube body respectively Passage 23.
