The other end edge of the follower lever is fixed with sliding pin, the sliding pin relatively described driving lever in rotary course
Circumferentially positioned radial direction is moved with being reciprocally moveable.
Further, the driving lever is provided with the groove radially extended as the center of circle with active rotation axle center, institute near the other end
Sliding pin is stated to be slided in the groove.
Further, the driven axis of rotation is located on same vertical curve with the active rotation axle center and the sliding pin
When, the active rotation axle center is located between the driven axis of rotation and the sliding pin.
Further, the driven axis of rotation and the distance in active rotation axle center are 28.3 millimeters.
Further, the driven axis of rotation is 50.2 millimeters to the distance of the sliding pin, and the driving lever rotates 90
When spending, the follower lever rotational angle is 44.2 degree.
A kind of power distribution cabinet operating mechanism, it is characterised in that：Including above-described rotating mechanism.
The utility model has the following advantages relative to prior art：
Tie point at the end edge of follower lever, is not being changed the premise of axis of rotation position by the utility model
Under, extend the radius of turn of driving lever so that driving lever needs the angle for turning over smaller.
