Embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of drawer interlocking mechanism of low-voltage load switch-box, comprise left push rod 21, the right push rod 22 in the drawer that is arranged on the low-voltage load switch-box and be positioned at left push rod 21 and the locking plate 3 of 22 of right push rods, locking plate 3 one ends and the installed part 4 activity attachings, the other end that are fixed in the drawer-bottom board upper surface and the through hole of offering on drawer-bottom board 5 are corresponding, and the position of this through hole 5 is positioned at the front upper place of the screw mandrel 18 of the bottom surface that is contained in drawer-bottom board.Also be provided with the return unit that is connected with locking plate 3 on drawer-bottom board, this return unit comprises connector 6 and extension spring 7, and connector 6 fixedly is loaded on the drawer-bottom board lower surface, and extension spring 7 one ends are loaded on the connector 6, the other end is connected with locking plate 3 one ends.Installed part 4 bottoms are installed with rotating shaft 8, and an end movable set of the locking plate 3 that is connected with extension spring 7 is in this rotating shaft 8, and locking plate 3 can rotate around this rotating shaft 8.
The fixed-site of corresponding left push rod 21 is equiped with alignment pin 91 No. one on the locking plate 3, and left side push rod 21 blocks alignment pin 91 No. one when promoting left push rod 21.Installed part 4 upper ends fixedly are equiped with No. two alignment pins 92 that are used to limit locking plate 3 strokes.
When left push rod 21 and right push rod 22 are installed, the left plate 10 that left side push rod 21 penetrates drawer extends in the drawer, the left side end fixed cover that exposes outside drawer left plate 10 of push rod 21 is equipped with left washer 11, also is set with the left stage clip 12 that is positioned at 10 of this left side washer 11 and drawer left plates on the left push rod 21; The right plate 13 that right push rod 22 penetrates drawer extends in the drawer, and the end fixed cover that right push rod 22 exposes outside drawer right plate 13 is equipped with right washer 14, also is set with the right stage clip 15 that is positioned at 13 of this right side washer 14 and drawer right plates on the right push rod 22.
In order to make left push rod 21 and right push rod 22 more reliable and more stable, on the upper surface of drawer-bottom board, also be fixed with left pusher bar support 16 and right pusher bar support 17, left side push rod 21 passes drawer left plate 10 and left pusher bar support 16 successively, and right push rod 22 passes drawer right plate 13 and right pusher bar support 17 successively.
Operating state of the present utility model is as follows,
When needing interruption maintenance, as shown in Figure 3, on-load switch to power network line carries out sub-switching operation earlier, get a rocking bar then, rocking bar is inserted the screw mandrel that is loaded on the drawer-bottom board bottom surface, by counterclockwise shaking screw mandrel, after shaking travel switch on the low-voltage load switch-box and sending the index signal that puts in place, can take out rocking bar.Again left push rod is applied to the right power, left push rod level is moved right, left push rod promotes an alignment pin on the locking plate, force locking plate to rotate around the shaft, along with constantly moving of left push rod, the locking plate other end moves down and passes through hole bumping post screw hole, and extension spring is stretched; Promote right push rod with horizontal thrust left again, make right push rod block locking plate, thereby locking plate is tightly blocked by left push rod and right push rod simultaneously, locking plate one end shelters from the screw hole position again, this moment, rocking bar can not insert in the screw mandrel, had avoided misoperation, safeguard work personnel's safety.
In the time of need sending electricity, as shown in Figure 2, at first remove horizontal thrust to right push rod, right push rod is owing to the elastic force that is subjected to adorning stage clip thereon automatically resets, make right push rod no longer stick locking plate, remove the horizontal thrust to left push rod again, the elastic force that left push rod is subjected to adorning stage clip thereon automatically resets, and makes an alignment pin on the not tight snapclose sheet of left push rod.Locking plate is under the tension of extension spring at this moment, and upwards rotation resets around the shaft, and the locking plate part of originally passing through hole moves up again, and then removes blocking screw hole.Can insert rocking bar is inserted in the screw mandrel this moment, the screw mandrel that moves in the direction of the clock, and drawer advances, and after shaking travel switch and sending the index signal that puts in place, can take out rocking bar, finishes transmission process.
The foregoing description is the utility model preferred implementation, need to prove, under the prerequisite that does not break away from inventive concept of the present utility model, any conspicuous replacement is all within protection range of the present utility model.
