Power-driven operation device

Abstract

The invention discloses a power-driven operation device for a miniature circuit breaker. The power-driven operation device comprises a shell, a round disc, a hook and a driving lever, wherein a motor is arranged in the shell, an output shaft of the motor is provided with a worm, and the round disc is arranged in the shell, the outer circumference of the round disc is provided with a groove, one side of the round disc is provided with a driving rod gear, and the other side of the round disc is provided with a driving rod round disc; the driving rod is arranged on the driving rod round disc through a connecting rod, and a gear set is arranged between the driving rod gear and the worm so as to transmit the power of the motor to the driving rod gear; the shell is provided with a sliding button connected with the hook; and the hook can be clamped in the groove on the round disc by driving the sliding button, and meanwhile, the end part of the hook is capable of withstanding the driving rod round disc to prevent the driving rod round disc from rotating. The power-driven operation device disclosed by the invention is simple in structure, reliable, low in cost, high in security and capable of locking the driving rod.

Description

technical field [0001] The invention relates to an improvement of an electric operating device, in particular to an electric operating device in a miniature circuit breaker with the function of locking a lever, which is simple in structure, reliable and low in cost. Background technique [0002] Under the premise of the continuous improvement of various indicators of the current miniature circuit breakers, the applicable occasions of the miniature circuit breakers are becoming more and more extensive. The miniature circuit breakers are basically used in the terminals of low-voltage power distribution, and automatic control and remote control functions are required. There are more and more occasions.

[0003] Existing electric operating devices for miniature circuit breakers, such as application number: 201120291912.0, title of invention: transmission mechanism for electric operating mechanisms for miniature circuit breakers discloses a transmission mechanism for electric operating mechanisms for miniature circuit breakers, including a housing, a housing A driving motor is installed in the body, and a handle that can rotate around a fixed axis is installed on the housing. A gear is installed at the lower end of the handle and is located in the housing. The gears mesh with the gears, and there is a gap between the crank arm and the matching device of the driving gear; the handle of the electric operating mechanism of the miniature circuit breaker with this structure cannot be locked. If the circuit breaks down and needs to be repaired, the handle may be misoperated, posing a safety threat to the maintenance personnel.
