Invention content
The purpose of this utility model is that there are the above problems for existing technology, it is proposed that a kind of arc-chutes quick acting switching-off
Disjunction mechanism, the disjunction mechanism of the arc-chutes quick acting switching-off the technical problem to be solved is that：How to enable arc-chutes fast
Fast separating brake.
The purpose of this utility model can be realized by following technical proposal：A kind of cutting machine of arc-chutes quick acting switching-off
Structure, including housing, moved end guide rod component and connecting lever component, the both ends expansion bearing of the moved end guide rod component on housing, and
The moved end guide rod component opposite housing can be stretched out or be retracted under connecting lever component effect, which is characterized in that described
Disjunction mechanism further includes elastic component, and the elastic component can be to the moved end when the moved end guide rod component is in stretching state
Guide rod component generates the active force for making it have movement tendency round about, and the elastic component first end is connected on housing,
The second end of the elastic component is connected on the moved end guide rod component.
The principle of the utility model is as follows：The moved end guide rod component of the disjunction mechanism of arc-chutes quick acting switching-off stretches out housing section
Divide and connect with the moving contact of arc-chutes, moving contact and static contact can be made to contact and close when moved end guide rod component stretches out housing
Lock, when moved end guide rod component is retracted housing, moving contact and static contact separate and separating brake.By in moved end guide rod component and housing
Between elastic component is set, make moved end guide rod component in "on" position, elastic component is compressed and moved end guide rod component generated anti-
It to active force, is retracted for moved end guide rod component into housing and pretightning force is provided, when connecting lever component drives moved end under external force
When guide rod component is retracted into housing, the pretightning force and external force collective effect of elastic component lead moved end on the guide rod component of moved end
Bar assembly is accelerated in the speed at initial stage that retraction acts, so as to improve opening velocity.
In a kind of disjunction mechanism of above-mentioned arc-chutes quick acting switching-off, the elastic component is from nature to compressive state
Compression travel be less than the moved end guide rod component from stretch out shape to contraction state movement travel.Here signified compressed line
Journey refers to that elastic component is in non-stress to the first end of elastic component during confined state along moved end guide rod component axial direction
Move distance, pass through this set so that at the initial stage that elastic component is retracted in moved end guide rod component in housing, elastic component can
As the power-assisted of moved end guide rod retraction, which improves the speed of moved end guide rod component retraction, helps to improve arc-chutes
Arc quenching effect；And moved end guide rod is further retracted and retraction is after the compression travel of elastic component is more than, the elastic force of elastic component

Embodiment two：
As shown in figure 4, in the present embodiment, the mechanism and embodiment one of disjunction mechanism are essentially identical, the difference lies in：Bullet
Property part 6 be spring 6b, spring 6b is set on moved end guide rod component 4, and moved end guide rod component 4 is equipped with annular convex platform 4a1, spring
6b one end and annular convex platform 4a1 against, the spring 6b other ends and housing 1 madial wall against.Scheme as a further preference,
Spring 6b is volute spring 6b, and one end that volute spring 6b is relatively large in diameter is resisted against on the madial wall of housing 1, and volute spring 6b is straight
The smaller one end of diameter is resisted against on annular convex platform 4a1.Using the spring 6b being set on moved end guide rod component 4 as elastic component 6,
Since spring 6b and moved end guide rod component 4 are co-axially mounted, the action direction of elastic force and an extreme direction one of moved end guide rod component 4
It causes, therefore the stability of the retraction of moved end guide rod component 4 is more preferable, and the elastic force of volute spring 6b can changing with compression Chengdu
Become and increase, when compressing to the limit, elastic force is maximum, with the contact of compressive state, close to annular convex platform 4a1 one end
Elastic force gradually decrease, gradually decrease in this way volute spring 6b to 4 retraction of moved end guide rod component action the later stage power-assisted, and by
Step changes into resistance, realizes power-assisted and steady excessive, the stationarity that raising moved end guide rod component 4 is retracted of resistance.
The principle of the utility model is as follows：The moved end guide rod component 4 of the disjunction mechanism of arc-chutes quick acting switching-off stretches out housing 1
Part connect with the moving contact of arc-chutes, when moved end guide rod component 4 stretch out housing 1 when can make moving contact and static contact contact and
It closes a floodgate, when moved end guide rod component 4 is retracted housing 1, moving contact and static contact separate and separating brake.When arc-chutes are in "on" position
When, at this time under the action of cam 5 lower part of connecting lever component 3 far from 5 center of circle of cam, 3 top of connecting lever component to separating brake component 2 into
Row squeezes accumulation of energy；Elastic component 6 deforms upon, the accumulation of energy simultaneously of elastic component 6；Excess of stroke spring 4c is equally extruded and generates acting in opposition
Power；When the rotational angle for changing cam 5, when so that the cam 5 is no longer bear against connecting lever 3 lower part of component, separating brake component 2 is to connecting lever component 3
Top act, make its drive moved end guide rod component 4 moved to the inside of housing 1, while the acting in opposition of excess of stroke spring 4c
Also collective effect on moved end guide rod component 4, makes it be retracted into housing 1, by more for power and the resilient force power of elastic component 6
The superposition that recast is exerted oneself makes moved end guide rod component 4 be retracted speed and is significantly increased, so as to improve opening velocity.In addition, elastic component 6
The later stage that 4 retraction of guide rod component acts in moved end becomes resistance, becomes flat retraction action, the buffering of cooperation excess of stroke spring 4c
Effect, moved end guide rod component 4 are retracted more steadily, so as to improve the stability of arc-chutes separating brake.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
