Electric operating mechanism

Abstract

The invention discloses an electric operating mechanism comprising a sliding block that is capable of driving a circuit breaker directly or indirectly to realize opening or closing based on own reciprocating motion. The electric operating mechanism also includes a cam, a connecting rod, one pair of guiding pressing plates, and a motor. One end of the connecting rod is in rotation connection with the cam and the other end rotates with the sliding block. The guiding pressing plates are arranged at the two opposite sides of the sliding block and enable the sliding block to slide back and forth. The motor drives the cam to make rotation by a gear set; the e output shaft of the motor is disposed downwardly. The cam is arranged right above the gear set; and the sliding block and the gear set arearranged in a horizontal direction. Compared with the prior art, the electric operating mechanism has the following advantages: the height of the electric operating mechanism is reduced effectively;the moving direction of the sliding block is controlled by the guiding pressing plates, so that the overall height of the mechanism is reduced and the cost is lowered; and since connecting structuresof all parts are dismounted conveniently, the parts can be replaced separately if any damage is caused and thus overall scrapping is not needed, so that the cost is lowered.

Description

technical field [0001] The invention relates to an electric operating mechanism. Background technique [0002] In the electric operating mechanism in the prior art, the cam and the slide block are usually arranged up and down, so that the overall height of the electric operating mechanism is very high, resulting in a relatively large occupied space. For example, the Chinese utility model patent No. ZL201720842222.7 discloses a secondary positioning mechanism of an energy storage electric operating mechanism. A crank is installed on the main shaft, and the crank is movably linked with the slider through a connecting rod. During the rotation of the main shaft, the crank can be driven. Turning, the slider can drive the circuit breaker handle to move back and forth during the reciprocating movement on the guide post, so that the circuit breaker can be switched between the closing state and the opening state. The slider, gear and cam of the electric operating mechanism are up an...

AI Technical Summary

Problems solved by technology

The slider, the gear and the cam of the electric operating mechanism are up and down structures, and the height is high, and the guide column is used as the guide for the slider to move, resulting in an increase in the thickness of the slider and the overall height of the mechanism.
