Embodiment
Referring to figs. 1 through Fig. 3, the isolating switch embodiment of the utility model insulated column link detachable is described further.
A kind of isolating switch of insulated column link detachable, comprise insulated column, connecting rod, gangbar 5, connecting rod comprises left connecting rod 3 and right connecting rod 4, and left connecting rod 3 is connected by gangbar 5 with right connecting rod 4, connecting rod comprises connecting portion 8, installation portion 7, insulated column is provided with bulge loop 9, and installation portion 7 is provided with the bolt removably connected with bulge loop 9, and left connecting rod 3 and right connecting rod 4 are provided with the bolt removably connected with gangbar 5.By such setting, when left connecting rod 3 breaks down damage, can be keeped in repair separately by the left connecting rod 3 of dismounting or directly be changed, save expense, improve efficiency, the assembly and disassembly of right connecting rod 4 in like manner; Left connecting rod 3 is connected with right connecting rod 4 by gangbar 5, achieves relatively rotating of two insulated columns.
Fig. 1 gives a kind of isolating switch integral vertical stereogram of insulated column link detachable, right insulated column 2 comprises positive stop strip 13 and limiting plate 14, right insulated column 2 also comprises base plate and fixed leg 10, limiting plate 14 is connected with base plate is vertical and is connected with fixed leg 10, positive stop strip 13 is vertically connected on bulge loop 9, positive stop strip 13 away from one end of bulge loop 9 and limiting plate 14 inconsistent, movable because fixed leg 10 is fixing bulge loops 9, this makes it possible to realize the restriction that right insulation rotates counterclockwise angle, positive stop strip 13 is provided with adjustable bolt away from one end of bulge loop 9, bolt and limiting plate 14 inconsistent, by screwing or unscrew the distance of the rectangular contact limiting plate 14 of stud adjustable limit, therefore, it is possible to realize the change of spacing angle, adjust according to actual needs, by setting the first stopping means, achieve the spacing counterclockwise of left insulated column 1, and the second stopping means achieves the spacing counterclockwise of right insulated column 2, and left insulated column 1 is relative with the motion of right insulated column 2, namely when left insulated column 1 rotates counterclockwise, right insulated column 2 rotates clockwise, just can realize counterclockwise with clockwise jointly spacing in conjunction with the first stopping means and the second stopping means like this, ensure that the fail safe that left insulated column 1 and right insulated column 2 use, be easier to realize simultaneously.
Left connecting rod 3 also comprises external connection portion 6, and external connection portion 6 is provided with the front motion bar and rear motion bar that are connected by bolt with left connecting rod 3, front motion bar and rear motion bar and corresponding threaded bolt contacts face copper facing.Often there is iron rust in contact-making surface in the past in use for some time, therefore the flexibility of front motion bar and rear motion bar can be affected, even may rear iron filings of long duration pile up cause before motion bar and rear motion bar stuck, by ensure that contact-making surface not easily gets rusty after contact-making surface copper facing, after employing a period of time, still there is good mobility, useful life increases, and fail safe improves.
The installation portion 7 of external connection portion 6, connecting portion 8, right connecting rod 4 is equipped with chamfering.This avoid and be scratched when operator link, improve the fail safe of operation; Installation portion 7 comprises Inner arc 11 and external arc 12, external arc 12 is identical with the diameter of bulge loop 9, can by bulge loop 9 positioning spiro pit of insulated column with rear left connecting rod 3 and right connecting rod 4 by arranging like this, align during concrete operations external arc 12 and bulge loop 9 edge, therefore improves operating efficiency.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
