But existing switch isolation ground connection linkage complex structure, complex operation, protective value is poor, is unfavorable for practical application.
Summary of the invention
For the problems referred to above, it is simple that the purpose of this utility model is to provide a kind of structure, and easy to use, fail safe is high, practical switch isolation ground connection linkage.
Realize the technical solution of the utility model as follows:
Switch isolation ground connection linkage, comprise fixed head, mechanism panel and interlock board, described fixed head and mechanism panel connect and compose a rectangular housing, interlock board is arranged in rectangular housing and also can moves left and right on mechanism panel, interlock board and mechanism panel fit, interlock board is provided with gathering sill, mechanism panel is provided with the plush copper be inserted in for bindiny mechanism's panel and interlock board in gathering sill, interlock board both sides are respectively arranged with carries out spacing position-limit mechanism to it, and interlock board both sides are provided with the fore shaft adapted with position-limit mechanism.
Have employed above-mentioned scheme, moving left and right of interlock board can make circuit disconnect, and electrical equipment is stopped using, and when circuit normally uses, interlock board is firmly pinned by position-limit mechanism, and the fore shaft of position-limit mechanism and interlock board can clamp mutually, prevents displacement.When serious overload or short circuit and the fault such as under-voltage occur circuit, by operation position-limit mechanism, interlock board is moved to the left or to the right, thus circuit is disconnected, play a protective role; Gathering sill not only plays connection function, can also limit the displacement of interlock board, prevents interlock board shift-out mechanism panel, can work in effective moving range, and structure is simple, and easy to use, fail safe is high, practical.
Described position-limit mechanism comprises and is arranged on rotatable blocking lever on fixed head, blocking lever is provided with at least one arc-shaped cam, the guide plate be arranged on fixed head is provided with below blocking lever, be provided with below guide plate overhead cam through guide plate and fixed head and outward extending door hanging column, door hanging column is connected by spring with between guide plate and can moves up and down, guide plate is also provided with and is fixed on a hanging column the gag lever post that interlock board limits, advantage can realize the effect of reducing when being arc-shaped cam rotation, thus a hanging column can be made to move up and down, gag lever post coordinates with the fore shaft of interlock board makes interlock board fix, but be separated with it by mobile gag lever post interlock board.
Described gag lever post parallels with blocking lever, guide plate is provided with the first chute moved up and down for gag lever post, one end of gag lever post extends to mechanism panel, mechanism panel is provided with second chute corresponding with the first chute, gag lever post is also connected with limiting plate, limiting plate is arranged on the outer surface of mechanism panel, advantage is that limiting plate is connected with gag lever post and may be used for fixture panel, the position-limiting action of gag lever post can be ensured like this, prevent gag lever post from departing from the second chute, thus lose the effect of locking interlock board.
Advantage is when normally using, and interlock board is positioned at the centre position of mechanism panel, and door hanging column withstands cam, when needs cut off circuit, rotate blocking lever, cam and then rotates, because cam is arcuate structure, so can by door hanging column toward pressing down, now gag lever post along with door hanging column press down while move down along the first chute and the second chute, such gag lever post is separated with the fore shaft of interlock board, be separated after interlock board just can move to the left or to the right, cut off circuit, realize the effect disconnected; Otherwise realize closed effect, structure is simple, easy to use.
