High production cost, installation are also inconvenient.
The content of the invention
In view of this, the purpose of this utility model be to provide it is a kind of it is simple in construction, cost is relatively low, stability is preferably small
The operating mechanism of type breaker.
In order to realize the above object operating mechanism of the utility model using such a miniature circuit breaker, including tripping,
Lock, moving contact, extension spring, lock torsion spring, handle, handle torsion spring, U-shaped bolt, upper pivot, lower pivot, pedestal, the upper pivot and
Under be pivotally secured within pedestal, have the first translot hole be arrangeding in parallel and the second translot hole, moving contact upper end hinged on moving contact
Connect hole, first the second translot of translot boring ratio hole length, the first translot hole and the second translot hole of moving contact be each passed through pivot and
Under be pivotally connected on pedestal, it is described lock pass through under be pivotally hinged on moving contact, lock torsion spring located at lock on, tripping hinge
The hinge hole of moving contact upper end is connected on, the handle is connected on pedestal, and handle torsion spring is located between pedestal and handle, U-shaped bolt
Connection handle and tripping, extension spring one end are connected on pedestal, and the other end is connected on the first translot hole of moving contact.
Said structure reduces the part of the operating mechanism of miniature circuit breaker, and structure is simpler, allows during closure and touches
Head contact keeps certain contact to stationary contact, allows moving contact to have certain initial kinetic energy during separating brake, improves breaking speed,
Reduce the arc time.
This practicality, which is further arranged to operating mechanism, also includes double golden pull bars, and double golden pull bars are in U-typed, double golden pull bar one end
To latch connection end, the other end is contact jaw, and centre is shaft, and there are one section of arc chute, arc chute in the lower end of the lock
There is translot on corresponding pedestal, lock connection end is connected on arc chute, and contact jaw is connected on translot.
Said structure makes double golden pull bars and snap fit more stable.
This practicality, which is further arranged to moving contact lower end, movable contact, and moving contact narrows upwards along movable contact, forms one
" V " type concave surface.
When said structure disconnects by contact, caused electric arc moves above by arc end carrying-off rather than toward moving contact.
This practicality, which is further arranged to lock, includes lock front, the lock back side, lock dropout face, limited block, and lock is de-
Buckle side protrudes backward, forms a trapezoid boss at the lock back side, limited block is located at the offside in lock dropout face, and moving contact is located at
Between trapezoid boss and limited block.
Anglec of rotation progress of the said structure to moving contact is spacing, allows moving contact to be rotated in normal working range.
This practicality is further arranged to the side that the first translot hole is connected with extension spring and assumed diamond in shape.
Said structure is maintained at a position to the stress point of moving contact by extension spring, allows the excess of stroke of extension spring to act on more preferably.

Embodiment
As Figure 1-5, the utility model is a kind of operating mechanism of miniature circuit breaker, including tripping 3, lock 2, dynamic is touched
First 4, extension spring 5, lock torsion spring 21, handle 6, handle torsion spring 61, U-shaped bolt 8, upper pivot 10, lower pivot 11, pedestal 1, double golden pull bars
7th, indication piece 9, upper pivot 10 and lower pivot 11 are fixed on pedestal 1, there is the He of the first translot hole 41 be arrangeding in parallel on moving contact 4
Second translot hole 42, the first translot hole 41 and the second translot hole 42 are Long Circles, and there is a hinge hole 45 upper end of moving contact 4, first
The translot hole 42 of translot hole 41 to the second is long, and the first translot hole 41 and the second translot hole 42 of moving contact 4 are each passed through pivot 10
It is connected to lower pivot 11 on pedestal 1, the lock 2 is hinged on moving contact 4 by lower pivot 11, and lock torsion spring 21 is located at lock
On button 2, tripping 3 is hinged on the hinge hole 45 of the upper end of moving contact 4, and indication piece 9 is sheathed in tripping 3, and the handle 6 is connected to base
On seat 1, handle torsion spring 61 is located between pedestal 1 and handle 6, and U-shaped bolt 8 connects handle 6 and tripping 3, the one end of extension spring 5 are connected to base
On seat 1, the other end is connected on the first translot hole 41 of moving contact 4, and the side that the first translot hole 41 is connected with extension spring 5 is in water chestnut
Shape.Double golden pull bars 7 are in U-typed, and double golden one end of pull bar 7 are lock connection end 71, and the other end is contact jaw 72, and centre is shaft
73, there is one section of arc chute 26 lower end of the lock 2, there is translot on the corresponding pedestal 1 of arc chute 26, latches connection end
71 are connected on arc chute 26, and contact jaw 72 is connected on translot.There is movable contact 43 lower end of moving contact 4, and moving contact 4 touches along dynamic
Point 43 narrows upwards, forms " V " type concave surface 44.Lock 2 include lock front 23, lock the back side 24, lock dropout face 22,
