Description

Technical Field

[0001] This utility model relates to the field of musical instruments, and in particular to a novel octave wheel assembly for electric wind instruments. Background Technology

[0002] The electronic wind instrument is an innovative instrument that combines traditional instruments with modern technology; it is also known as the electronic saxophone or electronic recorder. It uses electronic technology to simulate the sound of traditional wind instruments while possessing unique playing methods and functions. The electronic wind instrument can simulate hundreds of timbres, including the sounds of traditional wind instruments and other instruments, and can even create sounds never heard on real instruments.

[0003] The octave wheel is a knob on an electronic wind instrument used to adjust the instrument's pitch. By adjusting the octave wheel, the player can move the pitch of the wind instrument up or down by one octave.

[0004] In common octagonal rollers, the roller and shaft are in direct contact. As the roller rotates, it slides and rubs against the shaft, leading to wear, high rolling resistance, noise, and the need for regular maintenance. Poor contact is also a common problem. Adding a bearing directly between the roller and shaft results in greater wobble, is prone to poor contact, and is more complicated to assemble.

[0005] In order to solve the problems existing in the background art, this utility model provides a novel octave wheel assembly for electric blowpipes. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a novel octave wheel assembly for electric blowpipes.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A novel octave wheel assembly for an electric blowpipe includes an octave wheel bracket, an elongated groove above the bracket, an octave wheel within the groove, and a plug for connection to a fixed chamber on one side below the bracket. The octave wheel includes a roller and a shaft located in the middle of the roller. An annular groove is provided between the inner side of the roller and the outer side of the shaft, and ball bearings are provided within the annular groove. A retainer is provided between the ball bearings.

[0009] Furthermore, the cage includes multiple arcs, the sides of which meet to form a large arc, and each arc has a ball bearing in its hole.

[0010] Furthermore, each arc is a curved ring, and the outer surface of each arc is arc-shaped.

[0011] Furthermore, the octagonal wheel is connected to the long groove by a nut.

[0012] Furthermore, the outer end of the roller is provided with threads for connection with a nut.

[0013] Furthermore, a hexagonal hole is provided on the outer side of the inner bottom surface of the shaft, and the hexagonal hole is connected to the round hole at the bottom of the octagonal wheel.

[0014] Furthermore, a circuit board is provided on the lower side of the octagonal wheel bracket.

[0015] Furthermore, a sound-smoothing strip is provided on one side of the upper surface of the octave wheel bracket.

[0016] Furthermore, the outer surface of the roller is either knurled or smooth.

[0017] The advantages of this utility model are as follows: the octagonal wheel assembly has a compact structure, good electrical contact, minimal shaking during use, no rolling noise during rolling, avoids maintenance, and is easy to install by plugging into the fixed compartment, making operation simple.

[0024] The specific solutions and embodiments of this utility model will be further described with reference to the accompanying drawings.

[0025] When using the octave wheel, some people are used to using their left hand (dominant hand) and others are used to using their right hand (reverse hand). Therefore, the slide strips on the octave wheel assembly need to be positioned on the left or right side of the wind instrument, respectively. Figure 1 As shown, the mounting area of ​​the existing octave wheel assembly includes a forward socket 1 and a reverse socket 2 for connecting the octave wheel assembly.

[0026] like Figure 2-5A novel octave wheel assembly for an electric blower includes an octave wheel bracket 6, an elongated groove above the octave wheel bracket 6 containing an octave wheel 8, and a plug 4 for connection to a fixed chamber on one side below the octave wheel bracket 6. The octave wheel 8 includes a roller 12 and a shaft 13 located in the middle of the roller 12. An annular groove is provided between the inner side of the roller 12 and the outer side of the shaft 13, and ball bearings 9 are provided in the annular groove. A retainer 11 is provided between the ball bearings 9.

[0027] The 8-axis wheel assembly can be fixed in the fixed compartment in two ways. In these two installation methods, the 8-axis wheel assembly rotates 180 degrees and the plug 4 is inserted into the forehand or backhand position respectively. The same set of components can switch between forehand and backhand by adjusting the installation direction.

[0028] The cage 11 comprises multiple arcs, each containing a ball bearing 9 within a hole. These arcs are arranged on a large circumference. The arcs can also be closed rings as shown in the figure. Each arc is a curved ring, with its outer surface being arc-shaped. The outer surface shown in Figure 5 is the outer surface that makes up the large arc, while the inner surfaces can also have the same curvature. The balls 9 are separated from each other by the cage 11. The balls 9 are in close contact with the grooves of the inner ring of the roller 12 and the outer ring of the shaft 13 to reduce wobble and eliminate rolling noise.

[0029] The octagonal wheel 8 is connected to the long groove by the nut 5.

[0030] The outer end of the roller 13 is provided with a thread, which is used to connect with the nut 5 and fix it to the octagonal wheel 8 assembly.

[0031] The outer surface of roller 12 is either knurled or smooth.

[0032] The inner bottom surface of shaft 13 has a hexagonal hole 10 on the outer side, which is connected to the round hole at the bottom of the octagon wheel 8 and is used to engage with a screwdriver.

[0033] A circuit board 2 is provided on the lower side of the octave wheel bracket 6. A sound-sliding strip 7 is provided on one side of the upper surface of the octave wheel bracket 6.

[0034] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
