Specific implementation mode
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 includes breaker frame and one end With the pedestal 7 of breaker frame body articulated connection, the other end of pedestal 7 is equipped with spring stack, spring 9, bullet is set on spring stack Spring 9 is butterfly spring, and one end top of butterfly spring is press-fitted in the block machine of guide post upper end, and the cooperation of other end top pressure is open circuit Device frame body is relatively fixed on the spring base of connection, and when pedestal 7 is rotated around hinged end, 9 forced compression of spring provides elastic force. Pedestal 7 is that there are two the U-shaped groove structures of vertical parallel-plate for tool.
The moving contact 2 of breaker is connect by moving contact pull rod 3 with connecting rod 4, and the other end of connecting rod 4 is hingedly connected to push plate 6 on the position at middle part, and one end of push plate 6 is hingedly connected on insulated tension pole 5, and the other end is connected to bottom by regulating mechanism On seat 7, regulating mechanism is nut-screw rod adjustment structure, including adjusting screw rod 11 and adjusting nut 12 in the present embodiment, is adjusted The upper end for saving screw rod 11 is equipped with hinge hole, and 8 rolling assembling of axis pin in hinge hole, by axis pin 8 and adjusting screw rod 11 cut with scissors by push plate 6 It connects in succession.Two risers of pedestal 7 are equipped with the slot hole vertically extended, and the both ends of axis pin 8 are respectively from corresponding riser On slot hole in stretch out and with the hole wall block of slot hole both sides coordinate, in this way be conducive to enhance adjusting screw rod 11 connect with pedestal it is strong Degree.The bottom plate of pedestal is equipped with through-hole, the upper end block machine 121 with outward extension of adjusting nut 12, block machine block cooperation 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 equipped with outer hexagonal structure, and tightening sleeve 13 is fitted to tune by the interior hexagonal structure rotation stop being adapted to therewith It saves on nut, and the periphery of tightening sleeve 13 is equipped with for clamping the clamping structure tightened for spanner, is rotated and is twisted with spanner When fixed 13, tightening sleeve 13 drives adjusting nut on adjusting screw rod 11 along threads turn, is realized in rotation process and adjusts spiral shell Bar moves up and down, to drive push plate 6 to move up and down.Further include for the locking on pedestal that adjusting nut is locked Mechanism, retaining mechanism includes fastening nut 14 of the spinning on adjusting screw rod, the upper surface of fastening nut 14 in the present embodiment Apply upward jacking force to it with merging with the lower face top pressure of tightening sleeve 13, under the action of jacking force, tightening sleeve it is upper End face block cooperation is on the downside of the bottom plate of pedestal, in this way, being exactly that adjusting nut is relatively fixed on pedestal.Tightening sleeve packet The interior hexagonal structure of the pressing plate 131 for including body and being fixed on body one end, tightening sleeve is arranged in the inner circumferential of body, makes set Body constitutes rotation stop set 132, and tightening sleeve is easy to process using separate structure.
The actuating unit of the other end of insulated tension pole 5 and breaker connects, and when combined floodgate, actuating unit passes through insulated tension pole 5 It drives push plate 6 to be rotated around the articulated shaft of itself and pedestal, pushes moving contact 2 to move upwards by connecting rod 4 in rotation process, moving contact After 2 contact with static contact 1, actuating unit work on realize breaker the excess of stroke, at this time due to moving contact with static contact Fitting can not continue to move up, and pedestal is made to be rotated around its articulated shaft in this way, and spring stress compresses during base rotation, The elastic force of spring ensure that the contact between dynamic/static contact, increase contact area, to reduce contact resistance.It is practical raw During production, due to the influence of foozle, the practical excess of stroke of breaker can generate 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 adjusting, first unscrew fastening nut 14 with Wrench, then with pulling Hand is stuck on the periphery of tightening sleeve to rotate tightening sleeve, and tightening sleeve drives adjusting nut rotation, under the action of helicitic texture, adjust Section screw rod moves up, and moving contact can be driven to move up by connecting rod 4 when adjusting screw rod moves up, adjust spiral shell Bar can drive moving contact to move down when moving down by connecting rod 4, to realize the adjusting of breaker over-travel, adjust in this way Journey is simple and convenient, and avoids when the excess of stroke is adjusted and dismantled to breaker.
In above-described embodiment of invention, adjustment structure uses nut screw regulating mechanism, in other implementations of the present invention In example, the multiple pin holes of setting can also be spaceds on adjusting screw rod, by by the different location on adjusting screw rod pin hole and Bolt cooperation on pedestal, which is realized, to be adjusted;Adjusting nut rotation and matching by fastening nut and tightening sleeve are driven by tightening sleeve It closes and realizes that the locking of adjusting nut can also be arranged in the lower end of adjusting nut to downward in other embodiments of the invention The extended segment of certain length is stretched, the end of extended segment is provided for the outer hexagonal structure that spanner is tightened, and extended segment is close to pedestal Part on setting external screw thread and assemble a nut, the nut in tightening nuts makes the cooperation of the bottom plate block of itself and pedestal realize The locking of adjusting nut unscrews the nut on adjusting nut when needing to operate adjusting nut, then passes through the outer of extended segment end Six sides operate adjusting nut;Push plate constitutes yoke frame, and in other embodiments, yoke frame can also be column construction;It adjusts Nut can also be coordinated with tightening sleeve by keyway realizes that rotation stop is connect;Pedestal can also be vertically arranged or be obliquely installed, this When pedestal hinge joint and the position of spring be adaptively adjusted.
