[0032] Specifically, the electric operating mechanism mounting device of disconnecting switch in the present application includes a fixed mounting mechanism 10, an elbow arm adjusting mechanism 20, a transmission mechanism 30 and a connecting mechanism 40. The fixed mounting mechanism 10 is used to install the elbow arm adjusting mechanism 20, so that the new electric mechanism (not shown in the figure) to be replaced is connected below the elbow arm adjusting mechanism 20 and then installed on the disconnecting switch base 510 through the fixed mounting mechanism 10. Therefore, the bottom end of the elbow arm adjusting mechanism 20 is used to connect the electric mechanism. The elbow arm adjusting mechanism 20 is used to facilitate the connection between the electric mechanism and the vertical connecting rod 520, thereby solving the problem that the new electric mechanism cannot be directly connected with the vertical connecting rod 520 in the traditional direct installation mode. The elbow arm adjusting mechanism 20 is installed and connected in the circular channel 121 provided in the fixed mounting mechanism 10. The connecting mechanism 40 is used to be connected with the vertical connecting rod 520, and then the elbow arm adjusting mechanism 20 and the connecting mechanism 40 are drivingly connected through the transmission mechanism 30. Therefore, when the new electric mechanism rotates, it can drive the vertical connecting rod 520 to rotate, thereby realizing closing and opening, instead of the manual operating mechanism box 530. Therefore, it can be understood that since the new electric mechanism is connected to the bottom end of the elbow arm adjusting mechanism 20, in order to facilitate the normal rotation of the equipment, the elbow arm adjusting mechanism 20 is connected through the circular channel 121 and is rotatably arranged, so that it can be driven to rotate when the new electric mechanism rotates.

[0043] Further, the two ends of the transmission connecting rod 310 are axially adjustable.

[0044] It should be understood that the pull ring at the two ends of the transmission connecting rod 310 can be axially adjusted along the transmission connecting rod 310 through threaded connection, so as to adapt to the spacing distance between the disconnecting switch base 510 and the vertical connecting rod 520 of different models, thereby improving the product adaptability.

[0046] It should be noted that the connecting frame 110 is used to be connected on the support of the isolating switch base 510, and can be installed by welding connection mode, while the mounting support 120 is used to pass through the crank shaft 220 (through the circular channel 121 in its own interior), so that the electric mechanism connected on the crank shaft 220 is mounted on the isolating switch base 510 through the mounting support.

[0047] Further, the connecting frame 110 is provided with a long hole 111 extending along the horizontal direction, and the mounting support 120 is adjustably connected to the connecting frame 110 by passing through the long hole 111 through the bolt.
