[0007] Preferably, an inverted concave plate is fixedly mounted on the four corner ends of the bottom surface of the chair board, and a rotation hole is respectively provided on the front and rear side walls of the concave plate.

[0008] Preferably, the L-shaped plate is fixedly mounted on the inner side wall of the concave plate, and a threaded hole is provided on the vertical side wall of the L-shaped plate, and a sliding opening is provided on the top surface of the horizontal part of the L-shaped plate.

[0009] Preferably, a sliding block is fixedly mounted on the top surface of the movable plate, and the sliding block is movably mounted in the sliding opening, a convex groove is provided on the inner side wall of the movable plate, and a square limiting groove is provided on the outer side wall of the movable plate.

[0010] Preferably, the screw knob and the threaded hole are threadedly connected together, and a rotating block is fixedly mounted on the outer end of the screw knob, and the rotating block is movably mounted in the convex groove.

[0011] Preferably, a connecting block is fixedly installed on the top of the chair leg, and rotating rods are fixedly installed on both side walls of the connecting block. The rotating rod is movably installed in the rotating hole, and a square limit block corresponding to the square limit groove is also fixedly installed on the end wall of the inner end rotating rod.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The folding mechanism of the present invention cooperates with the use of the piano chair, and the screw knob is rotated to drive the movable plate to move inwardly through the rotating block, so that the square limit block is moved out of the square limit groove, and then the chair legs are rotated inwardly through the rotating rods on both sides of the connecting block at the top of the chair legs. After the chair legs are rotated ninety degrees, the screw knob is rotated again to make the rotating block push the movable plate to allow the square limit block to enter the square limit groove. In this way, the four chair legs on the piano chair can be folded in this way, so that after the chair legs are folded and stored, not only the overall structure size of the piano chair is reduced, but also the piano chair can be directly placed next to the piano or on the wall when it is no longer in use, thereby reducing the space occupied by the piano chair. At the same time, it is also convenient to carry or carry the piano chair in the future, thereby achieving the purpose of facilitating the storage and use of the piano chair.
