Description

Technical Field

[0001] The utility model relates to the technical field of accordions, in particular to a shoulder strap for an accordion. Background Art

[0002] The accordion is a keyboard instrument that can be played both solo and as an accompaniment. It can not only play beautiful monophonic melodies, but also polyphonic music. It can also play rich harmonies with both hands like a piano. The accordion has a grand sound and rich timbre variations. The clever combination of fingers and bellows can play music of many different styles.

DETAILED DESCRIPTION

[0023] See also Figure 1-5An accordion shoulder strap comprises an accordion body 1, an adjusting mechanism 2 is arranged on the outside of the accordion body 1, the adjusting mechanism 2 comprises a supporting plate 201, the outer surfaces of the supporting plate 201 are respectively fixedly connected with two shrinking belts 202 and two fixing columns 216, the outer surface of the accordion body 1 is fixedly connected with two connecting columns 215, the outer surface of each connecting column 215 is fixedly connected with a reinforcing plate 3, the front surface of each reinforcing plate 3 is fixedly connected with the back surface of the accordion body 1, and the connecting column 215 and the accordion body 1 can be reinforced by the reinforcing plate 3 to enhance the stability of the device.

[0024] The outer surface of each connecting column 215 is fixedly connected to the first connecting strap 203, the outer surface of each first connecting strap 203 is fixedly connected to the anti-slip belt 204, the outer surfaces of the two anti-slip belts 204 are commonly fixedly connected to the second connecting strap 205, the outer surface of each fixed column 216 is fixedly connected to the fixing block 6, the back side of each fixing block 6 is fixedly connected to the outer surface of the support plate 201, and the fixing block 6 can be used to reinforce the fixing column 216 and the support plate 201 to prevent them from shifting during use.

[0025] The outer surface of the second connecting strap 205 is fixedly connected to the first fixing strap 206, the outer surfaces of the two first connecting straps 203 are commonly fixedly connected to the second fixing strap 207, a protective shell 209 is provided on the outer side of the second connecting strap 205, and the back side of the accordion body 1 is fixedly connected to two reinforcement frames 4, and the inner wall of each reinforcement frame 4 is fixedly connected to the outer surface of the fixing column 216. The fixing column 216 and the accordion body 1 can be fixed by the reinforcement frame 4 to avoid the problem of displacement and instability during use.

[0026] The inner wall of the protective shell 209 is fixedly connected to the first bearing 210, the inner ring of the first bearing 210 is fixedly connected to the rotating disk 208, and the end of the rotating disk 208 close to the second connecting strap 205 is fixedly connected to the first gear 211. The inner wall of each reinforcement frame 4 is threadedly connected to two groups of fixing bolts 5, and the outer surface of each group of fixing bolts 5 is threadedly connected to the inner wall of the accordion body 1. The reinforcement frame 4 and the accordion body 1 can be fixed by the fixing bolts 5, thereby further enhancing the stability of the device.

[0027] The outer surface of the first gear 211 is meshed with two second gears 212, and each second gear 212 is fixedly connected to a winding roller 213 at one end close to the second connecting strap 205, and the outer surface of each winding roller 213 is fixedly connected to a second bearing 214. A rubber pad 7 is provided on the outer side of the accordion body 1, and the outer surface of the rubber pad 7 is fixedly connected to the outer surface of the support plate 201. The rubber pad 7 can provide a buffering effect on the support plate 201, thereby enhancing the applicability of the device.

[0028] The working principle of the utility model is as follows: when in use, firstly, the first gear 211 is rotated by twisting the rotating disk 208, and then the two second gears 212 are driven to rotate, and then the winding roller 213 is rotated, thereby the shrink belt 202 can be loosened, so that the accordion strap can be put on, and after the accordion strap is put on, the shrink belt 202 is retracted by using the rotating disk 208 to make the winding roller 213 shrink, so that the wearing effect can be achieved, and the use effect of the device is enhanced. When the accordion strap is worn, since the shoulder of the strap is made of the anti-slip belt 204, the strap can be effectively prevented from colliding with the performer's clothes. The friction between them is small and relatively smooth, which can easily cause the shoulder straps to slip off the wearer's shoulders, and has a good anti-slip effect, thereby enhancing the applicability of the device. When the wearer uses the accordion for a long time, the support plate 201 can distribute the pressure of the accordion on the shoulder straps, thereby achieving the purpose of saving effort when wearing the straps for a long time and enhancing the practical effect of the device. The rubber pad 7 provided on the support plate 201 can buffer the pressure of the accordion on the wearer, thereby achieving a better use effect, and can effectively avoid the problem that the accordion is large in size, which can easily cause the performer to consume a lot of labor when using the accordion for a long time, and the shoulder straps cause scratches on the shoulders.
