Abstract
A kind of breaker operating mechanism, move up and down for driving the insulation push rod of contact, comprise leading portion to be hubbed on swing arm on Shell of circuit breaker swingably and to be connected the driving mechanism driving swing arm leading portion to swing, it is characterized in that: described swing arm leading portion end face is formed with rail groove, described insulation push rod lower end is provided with the roller rolling and be disposed in rail groove, be provided with for making roller be in spring in rail groove all the time between described swing arm and described insulation push rod, swing up and down in process at swing arm leading portion, roller can move along rail groove, the frictional resistance between swing arm and insulation push rod can be reduced like this, make swing arm and the smooth and easy action of insulation push rod, extend the useful life of swing arm and insulation push rod.
Description
Technical field
The utility model relates to a kind of breaker operating mechanism.
Background technology
Vacuum circuit-breaker mainly comprises housing, vacuum interrupter is in the housing set, the fixed contact in vacuum interrupter is arranged on by fixing conducting rod, the moving contact in vacuum interrupter is arranged on by active conductive bar, the insulation push rod be connected with active conductive bar, connect the operating mechanism driving insulation push rod to move up and down, operating mechanism mainly comprises leading portion and is hubbed on swing arm on Shell of circuit breaker swingably and is connected the driving mechanism driving swing arm leading portion to swing, the front end of swing arm is flexibly connected with insulation push rod lower end, insulation push rod can be promoted move up and down when swing arm swings, resulting belt dynamic/static contact is closed with moving contact or be separated, at present, there is complex structure in being flexibly connected between swing arm with insulation push rod, action has some setbacks, serious wear, the problems such as useful life is short.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides that a kind of structure is simple, action is smooth and easy, the breaker operating mechanism of long service life.
The purpose of this utility model realizes by following technical solution:
A kind of breaker operating mechanism, move up and down for driving the insulation push rod of moving contact, comprise leading portion to be hubbed on swing arm on Shell of circuit breaker swingably and to be connected the driving mechanism driving swing arm leading portion to swing, it is characterized in that: described swing arm leading portion end face is formed with rail groove, described insulation push rod lower end is provided with the roller that is disposed in rail groove of rolling, and is provided with for making roller be in spring in rail groove all the time between described swing arm and described insulation push rod.
Further, described swing arm both sides are respectively arranged with lower connecting pin, and relative described insulation push rod both sides are respectively arranged with connecting pin, and described spring comprises in swing arm both sides and is stretched in two between upper and lower connecting pin.
Further, the width of described rail groove is slightly larger than the diameter of described roller.
Further, described rail groove is straight-line groove.
Further, described roller is by the ceramic bearing of bolt-locking in described insulation push rod lower end.
The utility model has following beneficial effect:
Be flexibly connected by roller and rail groove between swing arm with insulation push rod, in the process that swing arm leading portion swings up and down, roller can roll along rail groove, the frictional resistance between swing arm and insulation push rod can be reduced like this, make swing arm and the smooth and easy action of insulation push rod, wear and tear between peventing member, extend the useful life of swing arm and insulation push rod, in the downward swing process of swing arm, swing arm is moved downward by spring traction insulation push rod, spring can make roller and rail groove keep Structure deformation, can be used as again traction element and buffer element.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial left side view of Fig. 1.
Fig. 3 is structural representation of the present utility model, and swing arm leading portion makes dynamic and static contact be separated to lower swing.
Embodiment
With reference to shown in Fig. 1, Fig. 2 and Fig. 3, circuit breaker mainly comprises housing 1, arrange vacuum interrupter 2 within the case 1, be arranged on fixed contact in vacuum interrupter 2 by fixing conducting rod, be arranged on the moving contact in vacuum interrupter 2 by active conductive bar.
Breaker operating mechanism, comprises swing arm 4, driving mechanism and insulation push rod 3, and insulation push rod 3 is connected with active conductive bar.
Swing arm 4 is hubbed on Shell of circuit breaker swingably, driving mechanism connects driving swing arm 4 leading portion and swings up and down, driving mechanism is that prior art here no longer describes in detail, swing arm 4 leading portion end face is formed with linearly extended rail groove 41, insulation push rod 3 lower end is provided with the ceramic bearing 5 rolling and be disposed in rail groove 41, be provided with for making ceramic bearing 5 be in spring 6 in rail groove 41 all the time between swing arm 4 and insulation push rod 3, the width of rail groove 41 is slightly larger than the diameter of ceramic bearing 5, ceramic bearing 5 is arranged on insulation push rod 3 lower end by wheel seat, swing arm 4 both sides are respectively arranged with lower connecting pin 62, the wheel seat both sides of relative insulation push rod 3 are respectively arranged with connecting pin 61, spring 6 comprises and is positioned at swing arm 4 both sides and is stretched in, lower connecting pin 61, two between 62.
The above, be only preferred embodiment of the present utility model, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
