Description
Technical field
The present invention relates to a kind of circuit breaker, be specifically related to jockey between the circuit breakers pole between a kind of potting breaker two limit poles and middle pole.
Background technology
Traditional kettle style circuit breaker as shown in Figure 1, limit pole 61 and middle pole 71 form certain angle, middle pole 71 maintains static, the bottom of the tank body of limit pole is separately installed with a fixed pin shaft, limit pole 61 can rotate around fixed pin shaft, the angle of limit pole and middle pole can be adjusted like this, in order to reduce volume in Product transport process, two limit poles are adjusted to parallel with middle pole, behind scene, again two limit poles are adjusted to certain angle, also will guarantee the location of angle simultaneously.
The angle location of the limit pole of traditional kettle style circuit breaker, adjustment adopts jockey between circuit breakers pole as shown in Figure 2, pole, limit fixed mount 11 is equipped with pole, the limit bearing pin 21 that an Intermediate Gray is porose, interpole fixed mount 51 is equipped with the interpole bearing pin 41 that an Intermediate Gray is porose, one end of connecting rod 31 penetrates in the hole of pole, limit bearing pin 21, the other end penetrates in the hole of interpole bearing pin 41, being located through separately of pole, limit bearing pin 21 and interpole bearing pin 41, the adjusting nut in outside realizes, simultaneously by screwing or unscrew in pole, limit bearing pin 21, the adjusting nut in outside, the spacing of pole, limit fixed mount 11 and interpole fixed mount 51 can be adjusted respectively.When being applied on potting breaker, pole, limit fixed mount 11 is welded on the tank body of limit pole, interpole fixed mount 51 is welded on the tank body of middle pole, by the distance of adjusting edge pole fixed mount 11 with interpole fixed mount 51, just the angle of adjustable side pole and middle pole, can also guarantee the location of angle simultaneously.
But, the interpolar jockey of said structure, there is following problem: 1, connecting rod is fixed length part, distance between pole, limit fixed mount and interpole fixed mount, all the time the relative position with both on adjusting rod is corresponding, and the distance adjustment both namely being realized by the position of adjustment two fixed mounts on adjusting rod, when adjusting, must unclamp or tighten two adjusting nuts that two fixed mounts are corresponding, operate cumbersome; 2, because middle pole is fixed, position adjust of the interpole fixed mount corresponding with middle pole on adjusting rod can not be excessive, otherwise two interpolar jockeys of middle pole both sides can be made to interfere, it is longer that this just requires that connecting rod is positioned at the thread segment of fixed mount side, pole, limit, the adjusting nut of fixed mount side, pole, limit is made to need to screw in very long distance, adjustment is inconvenient and time-consuming, inefficiency; 3, in transportation, limit pole and middle pole want keeping parallelism, and this just requires the distance reducing pole, limit fixed mount and interpole fixed mount, but after reducing, it is long that pole, limit fixed mount is stretched out in one end that connecting rod is positioned at pole, limit fixed mount, easily collides with; 4, the hole passed for adjusting rod on pole, limit bearing pin and interpole bearing pin must ensure that adjusting rod can slide, if adjusting nut is not tightened, in transportation, adjusting rod generation axial motion, makes limit pole shake.
