Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, the interlocking mechanism of a kind of upper disconnecting switch, including: upper left isolator operating mechanism I, upper right isolator operating mechanism II, pull bar, adjusting nut and pin；It is characterized in that:
Described upper left isolator operating mechanism I includes: upper left isolator operation axle 1, left fixed mechanism version 3, connecting lever 4, screw rod A5, left slide mechanism plate 7, bent plate C17；
Connecting lever 4 is welded on the downside of upper left isolator operation axle 1, and screw rod A5 and left slide mechanism plate 7 are connected in left fixed mechanism version 3, and screw rod A5 can slide in the long lumbar hole in left fixed mechanism version 3, thus realizes horizontally slipping of left slide mechanism plate 7；Bent plate C17 is welded on left slide mechanism plate 7；
Described upper right isolator operating mechanism II includes: bent plate A9, right slide mechanism plate 11, screw rod B12, bent plate B13, upper right isolator operation axle 15, right fixed mechanism plate 16；
Bent plate A9 is fixed on the upside of upper right isolator operation axle 15, and screw rod B12 and right slide mechanism plate 11 are connected on right fixed mechanism plate 16, and screw rod B12 can slide in the long lumbar hole on right fixed mechanism plate 16, thus realizes horizontally slipping of right slide mechanism plate 11；Bent plate B13 is welded on right slide mechanism plate 11；
Described adjusting nut includes adjusting nut A6, adjusting nut B10, adjusting nut C14；
Described pull bar includes pull bar A2 and pull bar B8；Described connecting lever 4, pin 18 are connected with pull bar A2, and pull bar A2 is connected horizontally slipping of the right slide mechanism plate 11 of drive by adjusting nut C14 and bent plate B13, makes handle hole B opening and closing of fault；Bent plate A9, adjusting nut A6 are connected with pull bar B8, and pull bar B8 is connected horizontally slipping of the left slide mechanism plate 7 of drive by adjusting nut A6 and bent plate C17, makes handle hole A opening and closing of fault.
Pull bar A2 is hinged with connecting lever 4 by pin 18, and pull bar A2 is linked with bent plate B13 by adjusting nut C14, and pull bar B8 is connected with bent plate C17 by adjusting nut A6, and pull bar B8 is linked with bent plate A9 by adjusting nut B10.
In FIG, upper left isolator operating mechanism I and upper right isolator operating mechanism II are all in "on" position, and now the handle hole A of upper left isolator operating mechanism I is on, and the handle hole B of upper right isolator operating mechanism II is to close.Upper left isolator operating mechanism I must be first operated when needs operation upper right isolator operating mechanism II, at upper left isolator operating mechanism I handle hole A update instrument in Fig. 1, rotating 45 counterclockwise makes upper left isolator operating mechanism I be in gate-dividing state, the upper left isolator operation axle 1 of upper left isolator operating mechanism I drives pull bar A2 to act on bent plate B13 in the process, promote right slide mechanism plate 11 to slide to the right on right fixed mechanism plate 16, make the handle hole B of upper right isolator operating mechanism II open.
As in figure 2 it is shown, now operation instrument update hole B can be operated upper right isolator operating mechanism II.In fig. 2, upper left isolator operating mechanism I is in gate-dividing state, and upper right isolator operating mechanism II is all in "on" position, and now the handle hole A of upper left the isolator operating mechanism I and handle hole B of upper right isolator operating mechanism II is on.When needs operate upper right isolator operating mechanism II, the handle hole A of upper left isolator operating mechanism I time while making upper right isolator operating mechanism II be in gate-dividing state, must be made to close.In FIG at upper right isolator operating mechanism II handle hole B update instrument, rotating 45 counterclockwise and make upper right isolator operating mechanism II be in gate-dividing state, the right fixed mechanism plate 16 of upper right isolator operating mechanism II drives pull bar in the processB 8 act on bent plate C17, promote left slide mechanism plate 7 to slide to the left on right fixed mechanism plate 3, make the handle hole A of upper left isolator operating mechanism I close.
As shown in Figure 3.If upper left to be operated isolator operating mechanism I, must first operate the operation axle 16 of upper right isolator operating mechanism II, upper right isolator operating mechanism II is made to be in "on" position, pull bar B8 is made to act on bent plate C17, promoting left slide mechanism plate 7 to slide to the right on right fixed mechanism plate 3, the handle hole A of upper left isolator operating mechanism I just opens.
