Referring to fig. 1 and 2, an embodiment of the present invention provides an interlocking structure of a switching-on/off switch and a rocking handle, including an electric cabinet frame 100, a switching-on/off switch rotating member 200, a connecting rod 300, a supporting member 400, a linkage assembly 500 and a shielding plate 600 are arranged in the electric cabinet frame 100, the switching-on/off switch rotating member 200 is provided with an insertion through hole 210, the supporting member 400 is provided with a guide groove 410, one end of the connecting rod 300 is hinged to the switching-on/off switch rotating member 200, the other end of the connecting rod 300 is provided with a protruding rod 310, the protruding rod 310 passes through the guide groove 410 and slides in the guide groove 410, one end of the linkage assembly 500 is connected to the protruding rod 310, the other end of the linkage assembly 500 is connected to the shielding plate 600, and a front panel of; the opening and closing rotary member 200 rotates clockwise, the protruding rod 310 slides along the guide slot 410, and the linkage assembly 500 drives the shielding plate 600 to move and shield the crank insertion hole 110.
In this embodiment, an interlocking structure of opening and closing the brake to the crank insertion hole 110 is realized, and the opening and closing rotary member 200 and the shielding plate 600 are linked by the link 300, the support member 400 and the linkage assembly 500. After the switch is switched on, the electric cabinet drawer can be electrified and cannot be inserted into the rocking handle, otherwise, danger can be caused. When the switching-on/off rotating member 200 rotates clockwise to the switching-on position, the shielding plate 600 shields the crank insertion hole 110, and the crank cannot be inserted. When the rocking handle is inserted into the rocking handle insertion hole 110, the shielding plate 600 is blocked by the rocking handle and cannot move, so that the switching-on/switching-off rotating piece 200 cannot rotate to switch on, and at the moment, the electric cabinet drawer can only be in a switching-off state.
