Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figure 1-3, a kind of blocking lever, including upper joining beam 1 and lower joining beam 2, upper 1 lower end of joining beam and lower joining beam 2
Upper end is rotatablely connected, and guiding arc slot 22 is opened up on the lower joining beam 2, guide pad 11, the guide pad is arranged on the upper joining beam 1
11 are located in guiding arc slot 22, and torsional spring 5 is arranged between the upper joining beam 1 and lower joining beam 2, and described 5 one end of torsional spring abuts upper joining beam
1,5 other end of torsional spring abuts lower joining beam 2, and lower 2 lower part of joining beam is formed for blocking isolating switch mechanism handle hole
Occlusion part 21.
Axis hole is opened up on upper joining beam 1, the axis hole is respectively formed beam barrel 13 and lower beam barrel, upper 13 He of beam barrel in two sides up and down
It is integrated injection molding between lower beam barrel and upper joining beam 1 to be formed, the lower joining beam 2 is socketed on beam barrel 13, and the torsional spring 5 is socketed on
Beam barrel 13.
It is oriented to the at L-shaped structure of arc slot 22, guiding arc slot 22 therein one slightly arc, the guide pad 11 is L shape knot
Structure.Guide pad 11 is that L shape can prevent the relatively upper joining beam 1 of lower joining beam 2 from separating.
The side bumper block 12 for cooperating with upper 1 side of joining beam is formed on upper joining beam 1.Side bumper block 12 mainly plays lower joining beam 2
Position-limiting action.
Lower joining beam 1 connects reset tension spring 6, and reset state is in when for making blocking lever breaker mechanism separating brake.
As shown in figure 4, a kind of circuit breaker operation mechanism, including front baffle, output shaft, interlocking are provided in the front baffle
Connecting lever 4, gag lever post 50 and interlock support bar 3, the output shaft and front baffle are rotatablely connected, the interlocking connecting lever 4 and output
Axis is fixedly connected, and the interlock support bar 3 is fixedly connected with front baffle, and above-mentioned blocking lever is arranged on the interlock support bar 3,
The interlock support bar 3 is passed through from upper beam barrel 13 and lower beam barrel.
When breaker mechanism is in separating brake, lower joining beam 2 resets under the action of reset tension spring 6, upper joining beam 1 and gag lever post 50
Contact limit, at this point, the occlusion part 21 of lower joining beam 2 does not block the handle hole of interrupter, therefore, handle be can be inserted,
Interrupter can carry out on/off switch operation.
When breaker is in combined floodgate, the occlusion part 21 of joining beam 2 blocks the handle hole of interrupter under interlocking connecting lever 4 pushes,
At this point, handle can not be inserted into, interrupter cannot be operated.
In addition, when manual operation station, which leaves handle so output shaft, does combined floodgate movement, interlocking is turned when operation
Arm 4 drives upper joining beam 1 to rotate, and upper joining beam 1 drives lower joining beam 2 to rotate, so that the occlusion part 21 of lower joining beam 2 is moved to manual operation
Station can hit handle, so that the relatively upper joining beam 1 of lower joining beam 2 does elastic rotary, lower joining beam 2 exists after worker takes out handle at this time
Continue rotation under the action of torsional spring 5 to block manual operation station.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
