3 be set to 1 lower part of breaker body and be in integrated molding structure, the control switch 4 be set to 1 front central of breaker body and
It is connected by articulate, the manipulation hand handle 5 is set to 4 front of control switch and engagement connection, the protective device 6 of squeegeeing are set
In 1 inside of breaker body and it is located at 4 rear of control switch；
It is described squeegee protective device 6 by scaling squeegee air bag 61, circular arc item 62, push away mechanism of qi structure 63 and form, the scaling is mended
It stitches air bag 61 and is set to 4 lower edges rear of control switch, 62 both ends of circular arc item and scaling air bag 61 of squeegeeing are connected, described
It pushes away mechanism of qi structure 63 and is set to scaling and squeegee the lower section of air bag 61 and perforation connection.
The scaling squeegees air bag 61 by air bag 611, extruding slot 612, stretching structure 613, end cap 614,615 groups of spring
At the extruding slot 612 is set to 611 front surface of air bag and is in integrated molding structure, and the stretching structure 613 is uniformly equidistantly set
In 611 outer surface of air bag, the end cap 614 is set to 611 both ends of air bag and nested encryptions, 615 both ends of spring and end cap 614
Welding.
The air bag 61 of squeegeeing that scales sets there are two and is respectively arranged on 4 lower edges rear of control switch, by being equipped with
The expansion of 613 free shrink of stretching structure.
The circular arc item 62 is equipped with two and is set to 4 two sides of control switch in symmetry shape, and both ends are squeegeeed with two scalings
Air bag 61 is connected.
It is described push away mechanism of qi structure 63 by mechanism body 631, air cavity 632, push away gas plate 633, ejection block 634, electro-hydraulic compression bar 635,
Even gas hose 636 forms, and in bucket-shaped, the air cavity 632 is set to inside mechanism body 631 mechanism body 631, described to push away gas
Plate 633 is set to the inside of air cavity 632 and uses transition fit, the ejection block 634 be set to push away 633 front surface of gas plate and with electro-hydraulic pressure
The welding of 635 upper end of bar, electro-hydraulic 635 lower end of compression bar are flexibly connected with hydraulic cylinder, and the even gas hose 636 is passed through with air cavity 632
Lead to and connects.
The even gas hose 636 is equipped with 10-20 item, is uniformly equidistantly set to 632 two sides of air cavity, the even gas in two equal parts
636 both ends of hose are connected with air cavity 632, the perforation of air bag 611 respectively.
The inner end of the manipulation hand handle 5 is in semi-circular structure 5a, and the both ends the semi-circular structure 5a are equipped with engagement protrusion 5b, described
Manipulation hand handle 5 engages connection with the extruding slot 612 for scaling air bag 61 of squeegeeing by engagement protrusion 5b, and the semi-circular structure 5a's is interior
It is equipped with and fastens grain 5c, the manipulation hand handle 5 engages connection with control switch 4 by fastening grain 5c.
When the control switch 4 is in closed state, i.e., it is in be now placed in the air bag of 4 top edge of control switch to the bottom
611 be in swelling state when, just to control switch 4 close when top edge expose gap replenish.
When the control switch 4 is in open state, i.e., it is now placed in 4 lower edge of control switch in pendulum upwards at this time
When air bag 611 is in swelling state, the gap that lower edge exposes when opening just to control switch 4 is replenished.
Working principle of the present invention is as follows: breaker is installed on electric energy external surface, correctly connects route, Ji Ketong
Cross push away or under pull manipulation hand handle 5 and realize that manipulation control switch 4 controls breaker and unlatches and closes；When breaker to be opened
When, control switch 4 is swung up using fastening grain 5c by manipulation hand handle 5, the gap of 4 lower edge of control switch is because few at this time
Manipulation the blocking of hand handle 5 is completely exposed；While manipulation hand handle 5 above pushes away, the engagement protrusion 5b being equipped with using the upper end is embedding
Enter to squeeze in slot 612, extruding backward is applied to air bag 611, and under the effect of the elastic potential energy of spring 615, to 611 liang of air bag
End is squeezed, and the air in air bag 611 is squeezed into air cavity 632 by even gas hose 636, is now placed in control switch 4
The air bag 611 of lower surface loses the extruding of engagement protrusion 5b, and will push away gas plate 633 by electro-hydraulic compression bar 635, ejection is matched forward
It closes, the air of air cavity 632 is squeezed into another air bag 611 by spring 615, is issued in the auxiliary of stretching structure 613
Raw expansion, the exposed gap of 4 lower edge of control switch is blocked；When breaker to be closed, similarly make underlying gas
Capsule 611 is shunk, and the air bag 612 being located above expands, and the gap of 4 lower edge of control switch is blocked, worm ant, dust and water are prevented
Vapour enters circuit breaker internal by the gap.
Problems solved by the invention is that the external breaker of electric energy meter of the prior art is provided at electric energy external surface, in sudden and violent
It is exposed in external environment, because of swinging up and down for its switch, lower edges can there are its top edges when gap, the especially switch bottom
And its lower edge gap is larger when putting on switch, causes to have worm ant, dust and steam and enters circuit breaker internal, the present invention passes through
Above-mentioned component is combined with each other, and the present invention passes through the protective device of squeegeeing being equipped with, and can normally be put not influencing killer switch
Under the premise of dynamic, more flexibility by killer switch there are gap block, i.e. switch is following in when upwardly opening
Edge loses blocking for handle, exposes biggish gap, blocks the gap using the air bag of expansion, switchs top edge at this time
Because there is handle to block without processing of squeegeeing, air bag is in contraction state, can prevent it from influencing the swing of switch, can effectively prevent worm
Ant, dust and steam are entered circuit breaker internal, protective breaker.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention, for this field skill
