Embodiment 1
[0018] Such as Figure 1~2 As shown in the present invention, a self-leveling accordion sound hole cover, the sound hole cover body 1 is processed with a key rod groove 3 connected to the key rod 6, and the cross-sectional shape of the key rod groove 3 is bottom An inverted trapezoidal structure with shorter sides, the middle part of the key rod groove 3 is provided with a transverse protrusion 2 perpendicular to the key rod groove 3 .
[0019] When the key rod groove 3 is set as an inverted trapezoidal groove body, since both sides of the key rod groove 3 are sloped surfaces, even if the sound hole cover body 1 is not aligned before installation, when the key rod 6 is pressed down for installation, it will slide down along the slope, thereby Adjust the sound hole cover body 1. Certainly from this principle we know that the width of the bottom edge of the key bar groove 3 must be equal to or slightly greater than the rear diameter or thickness of the key bar 6, and the gap be...
Embodiment 2
[0022] Such as Figure 3-6 As shown in the present invention, a self-leveling accordion sound hole cover, the sound hole cover body 1 is processed with a key rod groove 3 connected to the key rod 6, and the cross-sectional shape of the key rod groove 3 is bottom An inverted trapezoidal structure with shorter sides, the middle part of the key bar groove 3 is provided with a transverse protrusion 2 perpendicular to the key bar groove 3; the two sides of the key bar groove 3 are processed with symmetrical sizing grooves 4 ; One end of the key rod groove 3 is provided with a plug 5, and the sound hole cover body 1 and the plug 5 are integrally formed.
[0023] On the basis of embodiment 1, in this embodiment, symmetrical sizing grooves 4 are processed on both sides of the lateral protrusion 2 of the key rod groove 3, and the lateral depth of the sizing grooves 4 is 1-4mm, and each is a sizing groove 4. The length along the installation direction of the key rod 6 is 5-15 mm. After...
