Abstract
The invention discloses a kind of tri-station isolating switch station locking mechanism.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, handle drives axle being provided with one can the handle of driving handle driving shaft and isolating switch main shaft synchronous axial system, alignment pin is provided with inside guidance panel, isolating switch main shaft is installed with the stop collar be positioned at inside guidance panel, the front end face of stop collar is provided with limited impression, between the axle head of stop collar rear end face and isolating switch main shaft, Compress Spring is installed.After adopting above-mentioned structure, when needs breaking-closing operating, turning handle can be undertaken spacing by alignment pin and positioning sleeve, stop the misoperation phenomenon of operating force difference in breaking-closing operating process and appearance completely, its vibrational power flow is simple, operation uses very convenient, and operating accuracy improves greatly, more substantially increase the reliability of use.
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, ground connection three stations, existing tri-station isolating switch is all generally comprise a handle, handle is connected with rotation axis, rotation axis is hinged with V-arrangement contact knife, by the action of handle drives V-arrangement contact knife, because tri-station isolating switch does not have reliable locking mechanism from closing position to open position and between open position to earthing position in existent technique, therefore be easy to misoperation in the course of the work, reliably can not carry out breaking-closing operating.
Summary of the invention
It is simple, easy to operate that the technical problem to be solved in the present invention is to provide a kind of structure, 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, handle drives axle being provided with one can the handle of driving handle driving shaft and isolating switch main shaft synchronous axial system, alignment pin is provided with inside guidance panel, isolating switch main shaft is installed with the stop collar be positioned at inside guidance panel, the front end face of stop collar is 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 also at least provided with one along the arrangement of guidance panel circumference, and limited impression is equal with the quantity of alignment pin.
After adopting above-mentioned structure, the alignment pin arranged inside stop collar on isolating switch main shaft and guidance panel is fixedly mounted on due to what arrange, be combined with simultaneously can only with the axial relative movement of isolating switch main shaft and can not circumference handle drives axle in relative rotation, thus when needs breaking-closing operating, turning handle can be undertaken spacing by alignment pin and positioning sleeve, stop the misoperation phenomenon of operating force difference in breaking-closing operating process and appearance completely, its vibrational power flow is simple, operation uses very convenient, operating accuracy improves greatly, more substantially increase the reliability of use.

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, the guidance panel 2 comprising isolating switch main shaft 1 and be fixed on isolating switch framework, isolating switch main shaft 1 also can move to axial with a nested installation of handle drives axle 3, handle drives axle 3 being provided with one can the handle 4 of driving handle driving shaft 3 and isolating switch main shaft 1 synchronous axial system, alignment pin 5 is provided with inside guidance panel 2, isolating switch main shaft 1 is installed with the stop collar 6 be positioned at inside guidance panel, the front end face of stop collar 6 is provided with the limited impression 7 relative with alignment pin 5 radial position, Compress Spring 8 is installed between the axle head of stop collar 6 rear end face and isolating switch main shaft 1, when gate-dividing state, the limited impression 7 that alignment pin 5 is positioned at stop collar 6 carries out spacing to it, prevent the rotation of positioning sleeve, when needs operate again, driving handle makes handle drives axle drive isolating switch main shaft 1 to extrude Compress Spring, positioning sleeve is made to depart from alignment pin 5, then turning handle can drive isolating switch main shaft 1 synchronous axial system to realize from separating brake to closing position action or separating brake to earthing position action, wherein, said alignment pin 5 is also at least provided with one along the arrangement of guidance panel circumference, limited impression 7 is equal with the quantity of alignment pin 5.
