Abstract
The invention discloses a position locking mechanism of a three-position isolating switch. The position locking mechanism comprises an isolating switch main shaft and an operation panel fixed on an isolating switch frame, the isolating switch main shaft and a handle drive shaft are mounted in a nested manner and can move axially relative to each other, the handle drive shaft is equipped with a handle that can drive the handle drive shaft to rotate synchronously with the isolating switch main shaft, an inner side of the operation panel is provided with a locating pin, the isolating switch main shaft is fixedly equipped with a position-limiting sleeve located at an inner side of the operation panel, a front end face of the position-limiting sleeve is provided with a position-limiting groove, and a compression spring is mounted between a rear end face of the position-limiting sleeve and a shaft end of the isolating switch main shaft. After adopting the abovementioned structure, when switching-closing operation is needed, the handle is rotated and position limiting can be performed through the locating pin and the locating sleeve, a misoperation phenomenon that occurs due to different operating force in the process of switching-closing operation is completely eradicated, and the position locking mechanism of the three-position isolating switch is simple in structure and very convenient to operate and use, and the operating accuracy and the use reliability are greatly improved.
Description
Technical field
The present invention relates to a kind of direct-current switch cabinet parts, specifically a kind of tri-station isolating switch station locking mechanism.
Background technology
Tri-station isolating switch is the switching mechanism with separating brake, combined floodgate, three stations of ground connection, existing tri-station isolating switch is all generally to comprise a handle, on handle, be connected with rotation axis, on rotation axis, be hinged with V-arrangement contact knife, by handle drives V-arrangement contact knife, move, in existent technique due to tri-station isolating switch from closing position to open position and open position to there is no reliable locking mechanism between earthing position, therefore be easy in the course of the work misoperation, can not reliably carry out breaking-closing operating.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, easy to operate, the tri-station isolating switch station locking mechanism that operation accurately, reliability is high.
In order to solve the problems of the technologies described above, tri-station isolating switch station locking mechanism of the present invention, comprise isolating switch main shaft and be fixed on the guidance panel on isolating switch framework, isolating switch main shaft also can move to axial with a nested installation of handle drives axle, on handle drives axle, being provided with one can driving handle driving shaft and the synchronous handle rotating of isolating switch main shaft, guidance panel inner side is provided with alignment pin, on isolating switch main shaft, be installed with the stop collar that is positioned at guidance panel inner side, on the front end face of stop collar, be provided with the limited impression relative with alignment pin radial position, between the axle head of stop collar rear end face and isolating switch main shaft, Compress Spring is installed.
Described alignment pin is arranged and is at least provided with one along guidance panel circumference, and limited impression equates with the quantity of alignment pin.
Adopt after above-mentioned structure, due to the alignment pin that stop collar on isolating switch main shaft and guidance panel inner side arrange that is fixedly mounted on arranging, coordinating simultaneously can only axially relatively move with isolating switch main shaft and can not be circumferentially handle drives axle in relative rotation, thus when needs breaking-closing operating, turning handle can be undertaken spacing by alignment pin and positioning sleeve, the misoperation phenomenon of having stopped operating force difference in breaking-closing operating process completely and having occurred, its structure arranges simply, operation is used very convenient, operating accuracy improves greatly, more greatly improved the reliability of using.

Embodiment
Below in conjunction with the drawings and specific embodiments, tri-station isolating switch station locking mechanism of the present invention is described in further detail.
As shown in the figure, tri-station isolating switch station locking mechanism of the present invention, comprise isolating switch main shaft 1 and be fixed on the guidance panel 2 on isolating switch framework, isolating switch main shaft 1 also can move to axial with a nested installation of handle drives axle 3, on handle drives axle 3, being provided with one can driving handle driving shaft 3 and the synchronous handle 4 rotating of isolating switch main shaft 1, guidance panel 2 inner sides are provided with alignment pin 5, on isolating switch main shaft 1, be installed with the stop collar 6 that is positioned at guidance panel inner side, on the front end face of stop collar 6, be provided with the limited impression 7 relative with alignment pin 5 radial positions, between stop collar 6 rear end faces and the axle head of isolating switch main shaft 1, Compress Spring 8 is installed, when gate-dividing state, the limited impression 7 that alignment pin 5 is positioned at stop collar 6 carries out spacing to it, prevented the rotation of positioning sleeve, when needs operate again, driving handle makes handle drives axle drive isolating switch main shaft 1 extruding Compress Spring, make positioning sleeve depart from alignment pin 5, then turning handle can drive synchronous rotation of isolating switch main shaft 1 to realize from separating brake to closing position action or separating brake moves to earthing position, wherein, said alignment pin 5 is arranged and is at least provided with one along guidance panel circumference, limited impression 7 equates with the quantity of alignment pin 5.
