Abstract
The utility model discloses a circuit breaker manual operation mechanism, including the support, install the operation rotor on the support, the support below has set firmly the internal gear, and internal gear and a loose gear meshing, loose gear are articulated with the one end of first connecting rod, the other end and the operation rotor fixed connection of first connecting rod, and the internal gear below is equipped with a slider, and the slider is articulated with the second connecting rod, second connecting rod and loose gear fixed connection are equipped with the pusher dog on the slider. When the operation rotor is rotated, the operation rotor can drive the movable gear to rotate in the inner gear, the movable gear drives the sliding block to slide through the second connecting rod, the shifting claw on the sliding block can drive the handle of the circuit breaker, the operation rotor can rotate 360 degrees in the same direction, also can rotate 180 degrees in the clockwise direction after rotating 180 degrees in the anticlockwise direction, and then can enable the circuit breaker to be opened or closed. The utility model has the advantages of reliable structure, small operating force and flexible operation.
Description
Technical Field
The utility model belongs to the technical field of the circuit breaker, concretely relates to manual operation mechanism of circuit breaker.
Background
The manual operation mechanism is to carrying out the operation of closing and opening to the circuit breaker of installing in the cabinet door from the cabinet door is outer, generally has the interlocking function with the cabinet door, opens when the cabinet door, and the circuit breaker can not be closed a floodgate, and when the circuit breaker in the position of closing a floodgate, the cabinet door can not be opened. The conventional manual operation mechanism is an eccentric mechanism mainly based on a cam structure, or a central mechanism mainly based on a rack and pinion type.
The existing defects are as follows: firstly, can't realize rotatory one direction and just can make the circuit breaker realize separating brake, combined floodgate operation simultaneously, must make the circuit breaker separating brake of anticlockwise rotation earlier when the operation, rethread clockwise rotation makes the circuit breaker combined floodgate. Secondly, the operation is hard, and the mechanism spring of circuit breaker can offset manual revolving force, especially to big shell frame product, can not bring good operation experience for the user.
Disclosure of Invention
The utility model aims to solve the technical problem that a manual operation mechanism with reliable structure, small operating force and flexible operation is provided.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme: the utility model provides a circuit breaker manual operation mechanism, includes the support, installs the operation rotor on the support, and the support below has set firmly the internal gear, and internal gear and a loose gear meshing, loose gear and the one end of first connecting rod are articulated, the other end and the operation rotor fixed connection of first connecting rod, and the internal gear below is equipped with a slider, and the slider is articulated with the second connecting rod, second connecting rod and loose gear fixed connection, are equipped with the pusher dog on the slider.
When the operation rotor rotates, the operation rotor can drive the movable gear to rotate in the inner gear, the movable gear drives the sliding block to slide through the second connecting rod, and the pusher dog on the sliding block can drive the handle of the circuit breaker to enable the circuit breaker to be opened or closed. The operation rotor can rotate 360 degrees in the same direction, also can rotate 180 degrees anticlockwise and then rotate 180 degrees clockwise, and can enable the breaker to be opened or closed.
