Description

Technical Field

[0001] This utility model relates to the field of flute technology, specifically a B-flat tailpipe for a flute. Background Technology

[0002] The B-flat tailpipe is a type of tailpipe for the flute. Flutes are generally divided into C-tailpipes and B-tailpipes, with the C-tailpipe being more common, while the B-tailpipe is relatively special. The B-flat tailpipe has multiple tone holes on its body, each with an openable / closable key cover. For example, there is a D-sharp auxiliary key on the top left side of the tailpipe, and adjacent to its right are a B-key auxiliary lever, a C-key movable wheel, and a C-sharp auxiliary key, as well as a B-key auxiliary button. These keys work together through a linkage mechanism to control the opening and closing of the tone holes, allowing for the playing of different pitches.

[0003] The existing application number is CN200910185335.4, "A variable-pitch flute". This patent allows flutists to play the tone of a bamboo flute, and can replace various bamboo flutes such as C, D, Bb, and G major. Its lowest note has a much wider range than that of the G major bamboo flute.

[0004] However, when using the existing B-flat tailpipe flute, the B-flat mouthpiece needs to be clipped to the front of the flute tailpipe for playing. The existing clipping method is a direct clip without any limiting measures on the outside, which makes it easy for the B-flat mouthpiece to shift position during playing, resulting in inaccurate tone.

[0005] Therefore, this utility model provides a flute B-flat tailpipe. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a flute B-flat tailpipe to solve the above problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a flute Bb tailpipe, including a flute tailpipe body, a Bb mouthpiece is snapped onto the outside of the flute tailpipe body, an installation mechanism is provided on the outside of the Bb mouthpiece, and a blow hole is opened inside the Bb mouthpiece.

[0008] The mounting mechanism includes a connecting ring, which is fixedly connected to the outside of the flute tailpiece body. A positioning groove is provided inside the connecting ring. A snap-fit ​​plate is fixedly connected to the outside of the Bb flute head. A limit hole is provided inside the snap-fit ​​plate. A rubber ring is fixedly connected to the outside of the connecting ring. A fixing rod is provided inside the rubber ring.

[0009] Preferably, a dustproof mechanism is provided on the outer side of the Bb-key mouthpiece. The dustproof mechanism includes a stabilizing ring, which is fixedly connected to the top of the Bb-key mouthpiece. A rotating rod is rotatably connected inside the stabilizing ring. A movable tube is fixedly connected to the outer side of the stabilizing ring. A moving rod is movably connected inside the movable tube. A compression spring is fixedly connected to the moving rod. An insertion hole is provided inside the rotating rod. A fixed plate is fixedly connected to the top of the rotating rod. A transmission tube is fixedly connected to the top of the fixed plate. A lifting rod is movably connected inside the transmission tube. A sealing plate is fixedly connected to the bottom of the lifting rod.

[0010] Preferably, the positioning grooves are symmetrically distributed inside the connecting ring, and the snap-fit ​​plate is on the same plane as the positioning groove. The snap-fit ​​plate enters the interior of the positioning groove by snapping and moving the B-flat flute head on the outside of the flute tailpiece body.

[0011] Preferably, the rubber rings are evenly distributed on the outer side of the connecting ring, and the fixing rod is located inside the limiting hole. Since the fixing rod is movably connected inside the rubber ring, and according to the material properties of the rubber ring itself, the fixing rod will have a certain friction force inside the rubber ring.

[0012] Preferably, the movable rod is movably connected to the inside of the movable tube by a compression spring, and the insertion holes are symmetrically distributed inside the rotating rod. The movable rod is moved into the inside of the insertion holes by the compression spring, thereby limiting the rotation rod.

[0013] Preferably, one end of the movable rod is located inside the through hole, and the fixed plate is rotatably connected above the B-flat mouthpiece via a rotating rod. The rotating rod rotates inside the stabilizing ring, thereby causing the fixed plate to rotate.

[0014] Preferably, the sealing disc is movably connected to the bottom of the fixed plate via a lifting rod, and the outer diameter of the sealing disc is smaller than the inner diameter of the blowing hole. The sealing disc is moved by the lifting rod, thereby sealing the blowing hole.

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The Bb tailpiece of this flute is first attached to the outside of the flute tailpiece body by snapping the Bb mouthpiece into it. The movement of the Bb mouthpiece can drive the snap plate on its outside into the positioning groove inside the connecting ring. At this time, the fixing rod moves inside the rubber ring, so that one end of the fixing rod enters the limiting hole inside the snap plate. There is a certain friction between the fixing rod and the rubber ring, so the snap plate can maintain stability inside the positioning groove and prevent the Bb mouthpiece from shifting position on the outside of the flute tailpiece body.

[0018] 2. When the blowhole inside the Bb tailpiece of this flute is not in use, the moving rod is pulled to move one end of the moving rod out of the through hole. At this time, the rotating rod rotates inside the stabilizing ring, thereby causing the rotating rod to move the fixing plate at the top of the Bb tailpiece. When the fixing plate moves the sealing plate to the top of the blowhole, the lifting rod moves inside the transmission tube, thereby causing the lifting rod to move the sealing plate into the blowhole, preventing external dust from entering the interior of the Bb tailpiece.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A flute with a B-flat tailpipe includes a flute tailpipe body 1, a B-flat mouthpiece 2 that is snapped onto the outside of the flute tailpipe body 1, an installation mechanism 3 that is provided on the outside of the B-flat mouthpiece 2, and a blow hole 5 that is provided inside the B-flat mouthpiece 2.

[0026] The mounting mechanism 3 includes a connecting ring 31, which is fixedly connected to the outside of the flute tail tube body 1. The connecting ring 31 has a positioning groove 32 inside. The outside of the Bb flute head 2 is fixedly connected to a snap-fit ​​plate 33. The snap-fit ​​plate 33 has a limit hole 34 inside. The outside of the connecting ring 31 is fixedly connected to a rubber ring 35. The rubber ring 35 has a fixing rod 36 inside.

[0027] Furthermore: the positioning grooves 32 are symmetrically distributed inside the connecting ring 31, the snap-fit ​​plate 33 is on the same plane as the positioning grooves 32, the rubber rings 35 are evenly distributed on the outside of the connecting ring 31, and the fixing rod 36 is located inside the limiting hole 34.

[0028] It should be noted that: by moving the B-flat mouthpiece 2 on the outside of the flute tailpiece body 1, the locking plate 33 enters the positioning groove 32. Since the fixing rod 36 is movably connected inside the rubber ring 35, and according to the material properties of the rubber ring 35, the fixing rod 36 will have a certain friction inside the rubber ring 35.

[0029] As a further improvement of this utility model, a dustproof mechanism 4 is provided on the outside of the Bb flute mouthpiece 2. The dustproof mechanism 4 includes a stabilizing ring 41, which is fixedly connected to the top of the Bb flute mouthpiece 2. A rotating rod 42 is rotatably connected inside the stabilizing ring 41. A movable tube 43 is fixedly connected to the outside of the stabilizing ring 41. A moving rod 44 is movably connected inside the movable tube 43. A compression spring 45 is fixedly connected to the moving rod 44. An insertion hole 46 is opened inside the rotating rod 42. A fixing plate 47 is fixedly connected to the top of the rotating rod 42. A transmission tube 48 is fixedly connected to the top of the fixing plate 47. A lifting rod 49 is movably connected inside the transmission tube 48. A sealing plate 410 is fixedly connected to the bottom of the lifting rod 49.

[0030] Furthermore: the moving rod 44 is movably connected to the inside of the moving tube 43 via the compression spring 45, the through holes 46 are symmetrically distributed inside the rotating rod 42, one end of the moving rod 44 is located inside the through hole 46, the fixed plate 47 is rotatably connected to the top of the Bb mouthpiece 2 via the rotating rod 42, the sealing plate 410 is movably connected to the bottom of the fixed plate 47 via the lifting rod 49, and the outer diameter of the sealing plate 410 is smaller than the inner diameter of the blow hole 5.

[0031] It should be noted that: the compression spring 45 causes the moving rod 44 to enter the interior of the insertion hole 46, thereby limiting the rotation rod 42. The rotation rod 42 rotates inside the stabilizing ring 41, thereby causing the rotating rod 42 to drive the fixed plate 47 to rotate. The lifting rod 49 drives the sealing plate 410 to move, thereby causing the sealing plate 410 to seal the blowing hole 5.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: With the flute tailpiece body 1 in place, the Bb mouthpiece 2 is first snapped onto the outside of the flute tailpiece body 1. The movement of the Bb mouthpiece 2 causes its outer snap-fit ​​plate 33 to enter the positioning groove 32 inside the connecting ring 31. At this time, the fixing rod 36 moves inside the rubber ring 35, causing one end of the fixing rod 36 to enter the limiting hole 34 inside the snap-fit ​​plate 33. The fixing rod 36 and the rubber ring 35 have a certain frictional force, thus maintaining the stability of the snap-fit ​​plate 33 inside the positioning groove 32 and preventing the Bb mouthpiece 2 from shifting position outside the flute tailpiece body 1. Furthermore, by setting up a Bb mouthpiece 2, when the blow hole 5 inside the Bb mouthpiece 2 is not in use, by pulling the moving rod 44, one end of the moving rod 44 is moved out from inside the insertion hole 46. At this time, the rotating rod 42 rotates inside the stabilizing ring 41, thereby causing the rotating rod 42 to drive the fixing plate 47 to move at the top of the Bb mouthpiece 2. When the fixing plate 47 drives the sealing plate 410 to move to the top of the blow hole 5, the lifting rod 49 moves inside the transmission tube 48, thereby causing the lifting rod 49 to drive the sealing plate 410 into the inside of the blow hole 5, preventing external dust from entering the inside of the Bb mouthpiece 2.
