Abstract
The utility model relates to an isolation switch, in particular to the isolation switch which is automatically and fully closed or is fully opened after an operation handle is rotated to some extent when the switch is closed or opened. The utility model has the following technical scheme: a cross-the-center closing isolation switch is characterized in that a cross-the-center rotating shaft automatic rotating device is arranged between a frame and a rotating shaft; the cross-the-center rotating shaft automatic rotating device comprises a transmission rod, a telescopic rod and a spring; one end of the transmission rod is connected onto the rotating shaft and is in circumferential linkage fitness with the rotating shaft, and the other end of the transmission rod is hinged with one end of the telescopic rod; the other end of the telescopic rod is hinged on the frame; the spring is sleeved on the telescopic rod, and the elastic force of the spring forms the extending force of the telescopic rod; and by adopting the scheme, the utility model overcomes the defects of the prior art, and provides the novel isolation switch in which the rotating shaft automatically rotates so that a moving contact and a static contact are fully closed or fully opened after the rotating shaft rotates to a certain position.
Description
Technical field
The utility model relates to a kind of isolating switch, is meant switch especially when closing a floodgate or disconnect, and operating grip rotates to the isolating switch that to a certain degree back realization is closed a floodgate or disconnected fully fully automatically.
Background technology
Present isolating switch has included only framework usually, fixed contact, moving contact, rotating shaft and linking arm, linking arm one end is connected in the rotating shaft, the other end is connected on the moving contact, moving contact is by the combined floodgate and the disconnection of rotating shaft realization and fixed contact, there are following defectives in the isolating switch of said structure: need artificial rotating shaft to put in place fully when closing a floodgate, could realize the combined floodgate fully of moving contact and fixed contact like this, the rotatory force that rotating shaft needed after fixed contact contacted with moving contact when closing a floodgate is just very big, if at this time operating personnel's carelessness or strength are easy to cause fixed contact and moving contact not to close a floodgate fully inadequately, the contact-making surface of fixed contact and moving contact is just little like this, electric current is very big, is easy to generate accident.
The utility model content
The utility model overcomes the prior art defective, provides a kind of after rotating shaft forwards certain position to, and rotating shaft is rotated automatically and realized moving contact and fixed contact closes a floodgate fully or the novel isolating switch of disconnection fully.
In order to realize above purpose, the utility model is by the following technical solutions: isolating switch closes a floodgate in a kind of mistake, include framework, fixed contact, moving contact, rotating shaft and linking arm, wherein fixed contact and moving contact are fixed on the framework by insulator respectively, rotating shaft is erected on the framework, linking arm is by connecting rod and insulated tension pole is hinged constitutes, one end of linking arm is that the end of connecting rod is fixedly connected in the rotating shaft, the other end of linking arm is that the end of insulated tension pole is connected on the moving contact, moving contact rotates combined floodgate and the disconnection that realizes with fixed contact by rotating shaft, it is characterized in that: be provided with the automatic tumbler of shaft between described framework and the rotating shaft, this is crossed the automatic tumbler of shaft and includes drive link, expansion link and spring, drive link one end is connected in the rotating shaft and constitutes with it and circumferentially is linked, one end of the other end of drive link and expansion link is hinged, the other end of expansion link is hinged on the framework, and described spring housing is located on the expansion link, and its elastic force constitutes the stretching force of expansion link.
By adopting such scheme, operating personnel only need rotating shaft behind certain position when needs close a floodgate or disconnect, and rotating shaft is owing to be subjected to the promotion of expansion link, thereby realize closing a floodgate fully and disconnecting fully, concrete principle is, when rotating shaft is rotated, as long as expansion link departs from axial location, at this time spring force just extends expansion link, thereby the promotion drive link, drive link drives rotating shaft and rotates, and realizes the purpose of closing a floodgate fully and disconnecting.
Further setting of the present utility model is: described expansion link is that two connecting rod sockets constitute, wherein connecting rod one end is fixed on the framework, and this end is provided with spring base, one end and the drive link of another root connecting rod are hinged, and this end also is provided with spring base, and spring is arranged between two spring bases.
By adopting such scheme, make the simple in structure of expansion link, easily manufactured, reliable.
Below in conjunction with accompanying drawing the utility model is described in further detail
