Abstract
A kind of circuit breaker semiaxis buckle side adjusting device, it comprises side plate (1, 1 '), double-pole lever (2) and separating brake semiaxis (3), separating brake semiaxis (3) two ends are contained in side plate (1, 1 ') on, double-pole lever (2) is contained on lever shaft (4), lever shaft (4) two ends are contained in side plate (1, 1 ') on, double-pole lever (2) one end contacts with separating brake semiaxis (3) and forms buckle side, it is characterized in that: described separating brake semiaxis (3) is through side plate (1, 1 ') adjustment screw (5) is provided with above one end, adjustment screw (5) is contained on side plate (1), adjustment screw (5) head of screw withstands separating brake semiaxis (3) can up-down adjustment.This device acts directly on separating brake semiaxis by adjustment screw, regulates year buckle side of double-pole lever and separating brake semiaxis, thus effectively controls the opening time of circuit breaker.Avoid occurring that actual year buckle side is bigger than normal, drop-away time lengthens, and affects electric life and the interrupting performance of circuit breaker; Also can avoid carrying buckle side less than normal, cause vibration in breaker closing process to cause mechanism's slide fastener.Improve degree of regulation high.
Description
Technical field
The utility model belongs to low voltage electrical apparatus technology field, specifically just relates to a kind of circuit breaker semiaxis buckle side adjusting device, realizes semiaxis buckle side size adjustable, improves the stability of semiaxis separating brake.
Background technology
Year buckle side of existing traditional omnipotent breaker is generally unadjustable, and owing to there is assembling and mismachining tolerance, actual year buckle side can exist deviation with a year buckle side for theory.When reality carry buckle side bigger than normal time, drop-away time can lengthen, and when there is larger overcurrent in circuit, contact system scaling loss is serious, affects electric life and the interrupting performance of circuit breaker; When reality carry buckle side less than normal time, circuit breaker is at making process Zhong Yishi mechanism slide fastener, and circuit breaker can not close a floodgate, produce misoperation.
In order to solve above-mentioned technical barrier, Chinese patent 200620140847.0 discloses a kind of low-voltage circuit breaker semiaxis buckle side adjusting device, it has lever, axle, side plate, semiaxis, connecting rod is formed, in the side of semiaxis, set up a semiaxis adjustment sheet, this semiaxis adjustment sheet is arranged on the side plate below semiaxis, this structure can make the buckle side of semiaxis reach adjustable, thus make separation release can in the voltage range specified time circuit breaker reliable separating brake, but this technical scheme adjustable range and the modulated plate shape of degree of regulation limit, each adjustment is all drive semiaxis to rotate the adjustment realized buckle side size by adjustment screw position in mounting hole by semiaxis adjustment sheet, adjustment process is complicated, precision is not high.
Utility model content
The purpose of this utility model is exactly complicated for existing circuit breaker semiaxis buckle side adjusting device adjustment process, the technological deficiency that degree of regulation is not high, a kind of circuit breaker semiaxis buckle side adjusting device is provided, governor motion is acted directly on semiaxis, realize the adjustment to the size of the buckle side that semiaxis and lever contact are formed, whole adjusting device structure is simple, and degree of regulation is high.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of circuit breaker semiaxis buckle side adjusting device of the utility model design, it comprises side plate, double-pole lever and separating brake semiaxis, separating brake semiaxis two ends are contained on side plate, double-pole lever is contained on lever shaft, lever shaft two ends are contained on side plate, double-pole lever one end contacts with separating brake semiaxis and forms buckle side, it is characterized in that: described separating brake semiaxis is provided with adjustment screw through above one end of side plate, adjustment screw is contained on side plate, and adjustment screw head of screw withstands separating brake semiaxis can up-down adjustment.
Further, described adjustment screw and separating brake semiaxis contact position are positioned at separating brake semiaxis rotation centerline side.
Further, described adjustment screw withstands separating brake semiaxis cantilever straight down.
Beneficial effect
The circuit breaker semiaxis buckle side adjusting device of the utility model design, acts directly on separating brake semiaxis by adjustment screw, regulates year buckle side of double-pole lever and separating brake semiaxis, thus effectively controls the opening time of circuit breaker.Avoid occurring that actual year buckle side is bigger than normal, drop-away time lengthens, and affects electric life and the interrupting performance of circuit breaker; Also can avoid carrying buckle side less than normal, cause vibration in breaker closing process to cause mechanism's slide fastener.Whole device only utilizes an adjustment screw just to achieve the object of carrying buckle side adjustment of separating brake semiaxis, and structure is simple, and easy to adjust, reliability is high.
Accompanying drawing explanation
Accompanying drawing 1 is product structure figure of the present utility model.
Accompanying drawing 2 is the utility model front views.
Accompanying drawing 3 is right views of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
As shown in accompanying drawing 1 ~ 3, a kind of circuit breaker semiaxis buckle side adjusting device, it comprises side plate 1,1 ', double-pole lever 2 and separating brake semiaxis 3, separating brake semiaxis 3 two ends are contained in side plate 1, on 1 ', double-pole lever 2 is contained on lever shaft 4, and lever shaft 4 two ends are contained in side plate 1, on 1 ', double-pole lever 2 one end contacts with separating brake semiaxis 3 and forms buckle side, it is characterized in that: described separating brake semiaxis 3 is provided with adjustment screw 5 through above one end of side plate 1,1 ', adjustment screw 5 is contained on side plate 1, and adjustment screw 5 head of screw withstands separating brake semiaxis 3 can up-down adjustment.
Described adjustment screw 5 is positioned at separating brake semiaxis 3 rotation centerline side with separating brake semiaxis 3 contact position.
Described adjustment screw 5 withstands separating brake semiaxis 3 cantilever straight down.
Under "on" position, double-pole lever 2 has counterclockwise rotation trend, props up separating brake semiaxis 3, and double-pole lever 2 is t with the buckle side of separating brake semiaxis 3, and adjustment screw 5 withstands separating brake semiaxis 3.Because existence assembling and mismachining tolerance, can there is deviation with a year buckle side for design in actual year buckle side.When reality carry buckle side bigger than normal time, adjustment screw 5 is rotated down, and separating brake semiaxis 3 rotates counterclockwise, and buckle side t reduces, drop-away time reduce; When reality carry buckle side less than normal time, a point brake lever rod 3 rotates clockwise, and buckle side t increases, not easily the phenomenon of generation mechanism slide fastener.
The circuit breaker semiaxis buckle side adjusting device structure of the utility model design is simple, acts directly on separating brake semiaxis by adjustment screw, regulates year buckle side of double-pole lever and separating brake semiaxis, thus effectively controls the opening time of circuit breaker.Avoid occurring that actual year buckle side is bigger than normal, drop-away time lengthens, and affects electric life and the interrupting performance of circuit breaker; Also can avoid carrying buckle side less than normal, cause vibration in breaker closing process to cause mechanism's slide fastener.Whole device only utilizes an adjustment screw just to achieve the object of carrying buckle side adjustment of separating brake semiaxis, and structure is simple, and easy to adjust, reliability is high.
