[0020] In order to better illustrate the content of the utility model, the following will be expanded and described in combination with the drawings and the embodiment:

[0021] There are Figures 1-4The utility model discloses an elevator alternating -current motor rotating shaft, including the axle 1, one end fixedly connected with the connecting disc 2 of axle 1, the annular edge place annular array of connecting disc 2 is provided with a plurality of notches 10, the fixed bolt 3 can be inserted into in the notch 10, the head and the tail of fixed bolt 3 are provided with the gasket 4, the gasket 4 of fixed bolt 3 tail is provided with the nut 5, the inner wall of notch 10 is slidably provided with the limiting column 9 that can be stuck fixed bolt 3, the side surface of connecting disc 2 close to axle 1 is inserted and slidably connected with control column 13, the inside of connecting disc 2 is provided with the locking mechanism 900 for extruding control column 13 through gasket 4 and controlling limiting column 9 to limit and lock fixed bolt 3.

[0022] Further, the locking mechanism 900 includes a sliding space 7 provided in the sidewall of the notch 10, the limiting column 9 is slidably arranged in the sliding space 7, the sliding space 7 is communicated with a limiting space 14, the limiting column 9 is provided with a connecting end 8 slidably connected to the limiting space 14, the first spring 6 is fixedly connected between the connecting end 8 and the inner wall of the limiting space 14.

[0023] Further, one end of the limiting column 9 is provided with an extrusion inclined surface 11.

[0024] Further, the left side of the sliding space 7 is communicated with an extrusion space 12, and the extrusion space 12 penetrates the left surface of the connecting disc 2.

[0025] Further, the extrusion space 12 is slidably connected with the control column 13 which can extrude and contact the extrusion inclined surface 11 of the limiting column 9.

[0026] Further, the control column 13 extrudes and contacts the gasket 4.

[0027] Specifically, in the initial state, the limiting column 9 is located inside the sliding space 7 under the tension of the first spring 6, and the control column 13 protrudes into the extrusion space 12 under the extrusion of the limiting column 9;

[0028] When the fixed bolt 3 needs to be connected, the fixed bolt 3 extends into the notch 10 and penetrates through the two gaskets 4, and when the nut 5 is continuously screwed in, the nut 5 moves and extrudes the gasket 4, so that the gasket 4 approaches the side surface of the connecting disc 2, and then the gasket 4 extrudes the control column 13 and presses the control column 13 into the inside of the extrusion space 12, at this time the limiting column 9 protrudes out of the sliding space 7 under the pushing of the control column 13, and the position of the fixed bolt 3 is locked and limited, that is, through the continuous tightening of the nut 5, the fixed bolt 3 itself is also limited in the notch 10;

[0029] When the fixing bolt 3 needs to be removed, only the nut 5 needs to be slightly screwed out, at this time the gasket 4 is no longer pressed by the nut 5, and then under the action of the first spring 6, the limiting column 9 will be pulled into the sliding space 7, at this time the fixing bolt 3 can be directly taken out, without completely unscrewing the nut 5.
