Abstract
The utility model discloses a cable branch is isolation switch mechanism for case in the cable branch case field, including setting up the switch body in the insulating cylinder, switch body one end is articulated with the interior moving contact of insulating cylinder, the middle part of the switch body is articulated mutually with isolation pull rod lower extreme, it is equipped with static contact and grounding contact respectively to correspond the switch body other end in the insulating cylinder, the insulating cylinder upside is equipped with actuating mechanism, actuating mechanism includes the swing arm that is connected with motor shaft, the swing arm tip articulates there is the intermediate draw bar, the intermediate draw bar other end is articulated mutually with a branch that has two ramose actuating levers, the actuating lever is the V font, two ramose department and fixed main shaft fixed connection of being connected of actuating lever, another branch of actuating lever is with to keep apart the pull rod upper end articulated mutually. The utility model discloses a set up actuating mechanism at the insulating cylinder upside for the bulk reduction of insulating cylinder, the structure of cable branch case is compacter, and the overall dimension of cable branch case is miniaturized, and the whole high transmission efficiency of mechanism saves the cost.
Description
Technical field
The utility model belongs to cable branch box field, is specifically related to a kind of isolation switch mechanism.
Background technology
In prior art, there is a kind of isolation switch mechanism, its structure comprises the knife brake be arranged in insulating cylinder, moving contact in one end of knife brake and insulating cylinder is hinged, the middle part of knife brake is hinged with the lower end of isolation pull bar, in described insulating cylinder, the other end of corresponding knife brake is respectively equipped with fixed contact and grounding contact, is provided with the cylinder for driving isolation pull bar in described insulating cylinder.During this institution staff, the piston rod external part of cylinder drives the motion of isolation pull bar, and isolation pull bar drives knife brake moving contact to rotate, and closes a floodgate when knife brake is connected with fixed contact, ground connection when knife brake is connected with grounding contact.Its weak point is: cylinder is arranged in insulating cylinder, the space that piston rod due to cylinder needs when stretching out motion is comparatively large, causes the volume of insulating cylinder also will become large thereupon, finally causes the size of cable branch box to become large, structure is compact not, increases production cost.
Utility model content
The purpose of this utility model is to provide a kind of cable branch box isolation switch mechanism, and make its compact conformation, transmission efficiency is high, reduces insulating cylinder volume.
The purpose of this utility model is achieved in that a kind of cable branch box isolation switch mechanism, comprise the knife brake be arranged in insulating cylinder, moving contact in one end of knife brake and insulating cylinder is hinged, the middle part of knife brake is hinged with the lower end of isolation pull bar, in described insulating cylinder, the other end of corresponding knife brake is respectively equipped with fixed contact and grounding contact, driving mechanism is provided with on the upside of described insulating cylinder, described driving mechanism comprises the swing arm be connected with machine shaft, swing arm end is hinged with intermediate draw bar, the other end of intermediate draw bar is hinged with a branch of the drive rod with Liang Ge branch, drive rod is in the shape of the letter V, the connection of described drive rod Liang Ge branch is fixedly connected with fixed main shaft, another branch of described drive rod is hinged with the upper end of isolation pull bar.
During utility model works, machine operation drives swing arm to rotate, and intermediate draw bar drives drive rod around main axis, and drive rod drives knife brake moving contact to rotate through isolation pull bar, close a floodgate when knife brake is connected with fixed contact, ground connection when knife brake is connected with grounding contact.Compared with prior art, the beneficial effects of the utility model are: by being arranged on the upside of insulating cylinder by driving mechanism, make the smaller volume of insulating cylinder, the structure of whole cable branch box is compacter, the overall dimension realizing cable branch box is miniaturized, whole mechanism driving efficiency is high, saves cost.
As further improvement of the utility model, described fixed contact is corresponding with the inlet wire conducting rod in insulating cylinder side-face wire feeding end to be connected.Long cable section of ingoing line is connected with fixed contact by inlet wire conducting rod.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is arranged in cable branch box.
Fig. 2 is structural representation of the present utility model.
Wherein, 1 insulating cylinder, 2 knife brakes, 3 moving contacts, 4 isolation pull bars, 5 fixed contacts, 6 grounding contacts, 7 swing arms, 8 intermediate draw bars, 9 drive rods, 10 main shafts, 11 ends of incoming cables, 12 inlet wire conducting rods.
Embodiment
As Fig. 1, shown in 2, for a kind of cable branch box isolation switch mechanism, comprise the knife brake 2 be arranged in insulating cylinder 1, moving contact 3 in one end of knife brake 2 and insulating cylinder 1 is hinged, the middle part of knife brake 2 is hinged with the lower end of isolation pull bar 4, in insulating cylinder 1, the other end of corresponding knife brake 2 is respectively equipped with fixed contact 5 and grounding contact 6, driving mechanism is provided with on the upside of insulating cylinder 1, described driving mechanism comprises the swing arm 7 be connected with machine shaft, swing arm 7 end is hinged with intermediate draw bar 8, the other end of intermediate draw bar 8 is hinged with a branch of the drive rod 9 with Liang Ge branch, drive rod 9 is in the shape of the letter V, the connection of drive rod 9 Liang Ge branch is fixedly connected with fixed main shaft 10, another branch of drive rod 9 is hinged with the upper end of isolation pull bar 4.Fixed contact 5 is corresponding with the inlet wire conducting rod 12 in insulating cylinder 1 side-face wire feeding end 11 to be connected.
During work, machine operation drives swing arm 7 to rotate, and intermediate draw bar 8 drives drive rod 9 to rotate around main shaft 10, and drive rod 9 drives knife brake 2 moving contact 3 to rotate through isolation pull bar 4, close a floodgate when knife brake 2 is connected with fixed contact 5, ground connection when knife brake 2 is connected with grounding contact 6.By being arranged on the upside of insulating cylinder by driving mechanism, make the smaller volume of insulating cylinder, the structure of whole cable branch box is compacter, and the overall dimension realizing cable branch box is miniaturized, and whole mechanism driving efficiency is high, saves cost.
The utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection range of the present utility model.
