[0014] Example 1

[0015] like Figures 1 to 3As shown, the utility model discloses a piano string axis support platform, including a supporting base plate 1, an adjusting screw 2, an adjusting nut 3, an adjusting base 4, a screw mounting seat 5, a screw 6, a slider 7, a slider locking nut 8, an adjusting base plate 9, a lifting screw 10, a locking nut 11, and a support plate 12; a rectangular notch is opened on the rear side of the upper surface of the supporting base plate 1, and an adjusting screw 2 is installed at the four corners of the lower surface; the adjusting screw 2 is installed in the adjusting base 4, can move up and down, and is equipped with an adjusting nut 3 to lock and fix; the screw mounting seat 5 is installed on the supporting base 1. The rear side of the upper surface of the bottom plate 1 is located on the left and right sides of the rectangular notch; the two ends of the screw rod 6 are installed on the screw rod mounting seat 5, and each screw rod 6 is equipped with two sliders 7. The slider 7 can move left and right on the screw rod 6, and the two sides are equipped with slider locking nuts 8 to fix; the adjustment bottom plate 9 is installed on the upper surface of the slider 7, connecting the sliders on the two screw rods 6, and a number of screw holes are opened in the center; the lifting screw 10 is installed in the screw hole of the adjustment bottom plate 9, and the upper and lower sides are equipped with locking nuts 11 to fix; the support plate 12 is welded and fixed to the top of the lifting screw 10. The support bottom plate 1 is a stainless steel flat plate with high flatness and strength, which is easier to fit with the piano center; the adjustment bottom plate 9 can move on the screw rod 6, and when using the adjustment bottom plate for support, it can move freely without moving the whole; the lifting screw 10 is detachable and can be installed separately according to the position of the string axis, so that the support point position is more free.

[0016] Working principle of the utility model: When the utility model is used, the whole is first moved to the lower side of the piano middle plate, and one of the supporting bottom plate 1, the adjusting bottom plate 9 and the supporting plate 12 is selected for support according to the fixing condition of the bottom of the middle plate. If a supporting base plate 1 is used for fixing, the adjusting screw 2 is lifted and lowered to make the supporting base plate 1 fit against the bottom of the middle disk, and the adjusting nut 3 is tightened to fix the adjusting screw 2; if an adjusting base plate 9 is used for support, the adjusting screw 2 is lifted and lowered to make the adjusting base plate 9 fit against the bottom of the middle disk, and the slider 7 is moved to move the adjusting base plate 9 to a suitable position, and then the adjusting nut 3 and the slider locking nut 8 are locked; if a support plate 12 is used for support, the adjusting screw 2 is lifted and lowered to make the adjusting base plate 9 close to the middle disk, and after moving the adjusting base plate 9 to a suitable position, the lifting screw 10 is rotated to make the support plate 12 fit against the middle disk, and then the adjusting nut 3, the slider locking nut 8, and the locking nut 11 are locked, and finally the chord to be replaced can be knocked into the blind hole of the chord plate to avoid plastic deformation of the chord plate or the middle disk due to excessive force or tilting.
