Abstract
The utility model relates to an operating mechanism of air circuit breaker, more specifically an operating mechanism of which the hand operation and the electric operation do not mutually interfere. In the operating mechanism, two parallel guide rails are installed on a housing by a bracket. Slide blocks on which a slide slot is installed are arranged on the guide rails. A cam passes through the slide slot by a pin shaft and then is connected to a driving mechanism, and a cambered slot is arranged on the cam. One end of a push axis is positioned in the cambered slot, and the other end is positioned in the slide slot of the slide block. The utility model has the characteristics of steady and reliable movement, no impact, long service life, etc.
Description
The utility model relates to the operating mechanism of air circuit, and is specifically a kind of manually and during electric operating, non-interfering operating mechanism.
The existing circuit breaker operating mechanism is as shown in Figure 2: motor drives cam 13 rotates, thereby drivening rod 14 is done straight reciprocating motion, and connecting rod 14 links to each other with circuit breaker handle by notch, realize the on/off switch action of circuit breaker, when manual, use palm moving axis 15, connecting rod 14 is outwards moved, break away from circuit breaker handle, could realize manual on/off switch, the manual, electronic of it connects each other simultaneously, can not realize trip avoidance function, cumbersome during operation, function ratio is less.
The purpose of this utility model is that design is a kind of simple in structure, and stable action is reliable, also has the breaker of plastic casing operating mechanism of trip avoidance function.
Its main technical schemes comprises shell and guide rail and cam slide mechanism, wherein two parallel guide rails utilize support to be installed on the shell, slide block is arranged on guide rail, and chute is set on slide block, after utilizing bearing pin to pass chute, a cam is connected with driving mechanism, a deep-slotted chip breaker is arranged on cam, one end of a push shaft is positioned at deep-slotted chip breaker, the other end is positioned at sliding fast chute, in the end of slide block one slotted hole is arranged, one end of hand lever connects bearing pin, and the other end connects another bearing pin, and the other end of this back one bearing pin is positioned at slotted hole.
The utility model has the advantages that the deep-slotted chip breaker that utilizes on the cam can be free to slide push shaft in this groove, electric operating and manual operation are not related to mutually, realized the trip avoidance function of circuit breaker; Secondly, in this device, push shaft can be free to slide in the slide block chute, as long as the friction that overcomes during action between push shaft and chute can be moved, significantly reduced used power of electric motor, reduced the volume of mechanism simultaneously, improved mechanism's traveling comfort, the noise when having reduced operation; The 3rd, push shaft and arc chute are in contact condition all the time during this device busy, thereby its stable action, do not have and impact.
During work, motor drives cam by reducing gear and rotates in the direction of arrows, the cam driven push shaft is by equidirectional rotation, push shaft links to each other with the slide block chute, can in the slide block chute, be free to slide, so push shaft can drive up and down rectilinear motion of slide block, move up and down thereby drive circuit breaker handle, reach close, the purpose of separating brake.Cam rotates a circle and can drive the upper and lower action of circuit breaker handle respectively once, this device also cam is provided with chute, thereby when carrying out manual operation with hand lever, push shaft can slide in deep-slotted chip breaker, thereby avoided the interlock of cam manually the time, reach the purpose of manual operation and electric operating mutually noninterfere, reduced the resistance when manual.In addition, this device is when electric operating, and push shaft contacts with the slide block chute all the time, has avoided the impact of push shaft to slide block, has prolonged the mechanical endurance of this mechanism.
