Embodiment
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment of the breaker of the present invention, as shown in Figures 2 to 7, breaker include breaker frame and one end
The base 7 being articulated and connected with breaker support body, the other end of base 7, which is provided with spring stack, spring stack, is set with spring 9, bullet
Spring 9 is butterfly spring, and one end top of butterfly spring is press-fitted on the gear platform of guide pillar upper end, and it is open circuit that other end top pressure, which coordinates,
Device support body is relatively fixed on the spring base of connection, and when base 7 is rotated around hinged end, there is provided elastic force for the forced compression of spring 9.
Base 7 is the U-lag structure with two vertical parallel-plates.
The moving contact 2 of breaker is connected by moving contact pull bar 3 with connecting rod 4, and the other end of connecting rod 4 is hingedly connected to push pedal
6 on the position at middle part, and one end of push pedal 6 is hingedly connected on insulated tension pole 5, and the other end is connected to bottom by governor motion
On seat 7, governor motion is nut-screw rod adjustment structure in the present embodiment, including adjusting screw rod 11 and adjusting nut 12 are adjusted
The upper end for saving screw rod 11 is provided with hinge hole, and the rolling assembling of bearing pin 8 is in hinge hole, and push pedal 6 is cut with scissors by bearing pin 8 with adjusting screw rod 11
Connect in succession.Two risers of base 7 are provided with vertically extending elongated hole, and the two ends of bearing pin 8 are respectively from corresponding riser
On elongated hole in stretch out and coordinate with the hole wall blocks of elongated hole both sides, be so beneficial to strengthen that adjusting screw rod 11 is connected with base is strong
Degree.The base plate of base is provided with through hole, and the upper end of adjusting nut 12 is provided with the gear platform 121 stretched out, and the gear platform block coordinates
In the upper hole of through hole along upper, the lower end of adjusting nut 12 is stretched out from the lower end of through hole, and extension constitutes rotation prevention portion 122, rotation stop
The periphery in portion 122 is provided with outer hexagonal structure, tightens set 13 and is coordinated by the interior hexagonal structure rotation stop being adapted to therewith installed in tune
Save on nut, and tighten the periphery of set 13 and be provided with the clamping structure for being used for being tightened for spanner clamp, rotated and twisted with spanner
During tight set 13, tighten set 13 and drive adjusting nuts on adjusting screw rod 11 along threads turn, regulation spiral shell is realized in rotation process
Bar is moved up and down, so as to drive push pedal 6 to move up and down.Also include being used for the locking on base that adjusting nut is locked
Mechanism, in the present embodiment retaining mechanism include spinning the clamp nut 14 on adjusting screw rod, the upper surface of clamp nut 14
Apply upward jacking force to it with tightening the lower surface top pressure of set 13 with merging, in the presence of jacking force, tighten the upper of set
End face block coordinates on the downside of the base plate of base, is exactly that adjusting nut is relatively fixed on base so.Tighten set bag
The pressing plate 131 for including body and being fixed on body one end, the interior hexagonal structure for tightening set is arranged in the inner circumferential of body, makes set
Body constitutes rotation stop set 132, tightens set and is easy to processing using Split type structure.
The other end of insulated tension pole 5 and the actuating unit of breaker are connected, and during combined floodgate, actuating unit passes through insulated tension pole 5
Drive push pedal 6 to be rotated around it with the jointed shaft of base, promote moving contact 2 to move upwards by connecting rod 4 in rotation process, moving contact
After 2 contact with static contact 1, actuating unit, which works on, realizes the excess of stroke of breaker, now due to moving contact with static contact
Laminating can not be continued to move up, and base is rotated around its jointed shaft, spring stress compresses during base rotation,
The elastic force of spring ensure that the contact between dynamic/static contact, increase contact area, so as to reduce contact resistance.It is actual raw
During production, due to the influence of foozle, the actual excess of stroke of breaker can produce error with the design excess of stroke, it is therefore desirable to carry out
The excess of stroke is adjusted.When breaker in the present embodiment carries out excess of stroke regulation, first unscrew clamp nut 14 with Wrench, then with pulling
Hand is stuck on the periphery for tighten set tightens set to rotate, and tightens set and drives adjusting nut to rotate, in the presence of helicitic texture, adjusts
Section screw rod is moved up, and by connecting rod 4 moving contact can be driven to move up when adjusting screw rod is moved up, be adjusted spiral shell
Bar can drive moving contact to move down when moving down by connecting rod 4, so as to realize the regulation of breaker over-travel, so adjust
Journey is simple and convenient, and breaker is dismantled when avoiding excess of stroke regulation.
In above-described embodiment of invention, adjustment structure uses nut screw governor motion, in other implementations of the present invention
Example in, can also on adjusting screw rod the multiple pin-and-holes of interval setting, by by the pin-and-hole at the diverse location on adjusting screw rod with
Latch on base, which coordinates, realizes regulation；Adjusting nut is driven to rotate and by clamp nut with tightening matching somebody with somebody for set by tightening set
The locking for realizing adjusting nut is closed, in other embodiments of the invention, can also be set in the lower end of adjusting nut to downward
The extension of certain length is stretched, the end of extension is provided for the outer hexagonal structure that spanner is tightened, and extension is close to base
Part on external screw thread be set and assemble a nut, the nut in tightening nuts makes it with the base plate block of base coordinate to realize
Then the locking of adjusting nut pass through the outer of extension end, it is necessary to when operating adjusting nut, unscrew the nut on adjusting nut
Six sides operate adjusting nut；Push plate constitutes yoke frame, and in other embodiments, yoke frame can also be column construction；Regulation
Nut can also realize that rotation stop is connected with tightening set by keyway cooperation；Base can also be vertically arranged or be obliquely installed, this
When base pin joint and the position accommodation of spring.
