Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figures 1 to 7, this breaker tripping mechanism includes being installed on support by being socketed with the axle 1 of torsion spring 1
Trigger assembly 2 on 1, constitutes the first transmission；By being socketed with the latch components that the axle 28 of torsion spring 27 is installed on support 1
5, constitute the second transmission.
Further, the trigger assembly 2 of first transmission is provided with for touching touching for circuit breaker handle bar linkage structure
The 2-2 of arm one is sent out, for arranging the 2-3 of trigger arm two of frizzen 6, for the locking boss 2-4 being engaged with latch components 5, with
And the 2-1 of torsion spring hole clipping two of the one end for clamping torsion spring 1, the other end of torsion spring 1 is connected in the torsion spring on support 1
In the 1-4 of hole clipping one.
In trip status, trigger assembly 2 is set to have what the axis direction along axle 1 was rotated by the twisting force of torsion spring 1
Trend, while locking boss 2-4 lock platform tight against latch components 5 in setting of the trigger assembly 2 with setting on a component 2 is touched
The upper limb of 5-4.
Further, the latch components 5 of second transmission be provided be plugged in it is spacing in the upper limit position groove 1-2 of support 1
Boss 5-1, for the stage clip buckle 5-3 of clamping stage clip 10, for trigger assembly 2 in the locks that coordinate of locking boss 2-4
Platform 5-4, and the 5-2 of torsion spring draw-in groove two of the one end for clamping torsion spring 27, the other end of torsion spring 27 is connected in located at support 1
On the 1-3 of torsion spring draw-in groove one in.
In trip status, latch components 5 are made to have the trend rotated along the axis direction of axle 28 by the effect of torsion spring 27
Simultaneously latch components 5 drive the lower edge of the locking boss 2-4 arranged in latch components 5 to be against the upper limb of lock platform 5-4.
Further, as shown in fig. 6, stage clip 10 is a curved bar type metal elastic force part, one end and the latch components 5 of stage clip 10
Dynamic, remaining main part of stage clip 10 is positioned as desired by multiple stage clip buckle 5-3.
Further, as shown in figure 1, offer on the support 1 one for coordinate installation breaker main shaft escape groove 1-
5.It is easy to the installation of breaker.
As shown in Figures 2 to 7, dead bolt 9 is not the main component of this breaker tripping mechanism, but on breaker
Drive mechanism, for convenience of the reference object arranged to the description of mechanism.
The operation principle of this breaker tripping mechanism is as follows：
Trip status：Dead bolt 9 leaves latch components 5, trigger assembly 2 is had along axle 1 by the twisting force of torsion spring 1
The trend that axis direction is rotated, while trigger assembly 2 sends out the locking boss 2-4 arranged on component 2 tight against in lock group with shake-up
The upper limb of the lock platform 5-4 arranged on part 5.Latch components 5 are made to have the axis direction along axle 28 to rotate by the effect of torsion spring 27
Trend, while latch components 5 drive latch components 5 on arrange locking boss 2-4 lower edge be against latch platform 5-4 it is upper
Edge, realizes threading off.
Lock process：Dead bolt 9 is rotated by the driving of breaker link mechanism to the direction of close latch components 5, when dead bolt 9
Root edge when compressing stage clip 10, stage clip 10 drives the axle that latch components 5 overcome the torsion of torsion spring 27 to make latch components 5 along axle 28
Line direction rotates, and the side of the lock platform 5-4 in latch components 5 abuts with the end face of dead bolt 9, until dead bolt 9 penetrates lock
The lower edge of platform 5-4 is detained, now trigger assembly 2 is acted on by torsion spring 27, insert the locking boss 2-4 being arranged on trigger assembly 2

2, the 2-2 of trigger arm one drive trigger assembly 2 to rotate around axle 1, make locking boss 2-4 slip away and latch the side of platform 5-4, while lock
Buckle assembly 5 is rotated by the effect of torsion spring 27 around axle 28, and dead bolt 9 is skidded off from the bottom side of lock platform 5-4, and dead bolt 9 is upspring realization
Thread off.
Automatic dropout process：During the tripping relay action touch trigger bar 6 such as the overload of breaker, short circuit, under-voltage, triggering
Bar 6 drives trigger assembly 2 to rotate around axle 1 in the presence of the 2-3 of trigger arm two, makes locking boss 2-4 slip away and latches platform 5-4
Side, while latch components 5 by torsion spring 27 effect around axle 28 rotate, dead bolt 9 from lock platform 5-4 bottom side skid off,
Dead bolt 9 is upspring and realizes threading off.
In sum, this breaker tripping mechanism solves the structure problem of circuit breaker tripping by said structure, optimizes
Breaker releasing structure, reduces the requirement of breaker manufacturing process and assembly technology, you can improve the production effect of breaker
Rate, can improve the reliability of breaker again, also allow for breakdown maintenance and the functional rehabilitation of breaker.
