Description
Technical field
The utility model relates to a kind of Manual adjustable insulating bar for operate high pressure electric equipment.
Background technology
The action bars of the operation of operating a switch to high voltage electric equipment is generally all regular length, is not easy to carry, just need to long action bars for the higher or longer-distance operation of operating a switch, and in small space, long action bars can not use again, can only change short operation bar again.Also there is at present flexible action bars, this action bars is made up of fixed lever and motion bar, between fixed lever and motion bar, adopt rotary fastening structure to carry out fastening, because being pipe, fixed lever and motion bar make, in the course of time, because rotary fastening structure adopts the mode of screw threads for fastening, firmly twist the situation that there will be stripped thread, it is fixing not firm to cause regulating after length.
Utility model content
The utility model is in order to solve weak point of the prior art, the Manual adjustable insulating bar of time saving and energy saving when a kind of adjusting is provided, the phenomenon of avoiding occurring sliding axially.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of Manual adjustable insulating bar, comprise lower insulated tube and upper insulated tube, upper insulated tube lower end is plugged in lower insulated tube, upper insulated tube upper end is provided with operating head, inside, described upper insulated tube lower end is provided with movable block, lower insulated tube lower end is provided with fixing closure plate, upper insulated tube is in axial direction arranged with twice pilot hole, lower insulated tube upper end is provided with the guide pad through pilot hole, between two guide pads, be provided with the locating piece of collar plate shape, locating piece external diameter is less than lower insulated tube internal diameter, between locating piece and fixing closure plate, be rotatably connected to screw mandrel, screw mandrel passes movable block and is threaded with movable block, screw mandrel, line setting that lower insulated tube and upper insulated tube are concentricity, screw mandrel lower end is connected with the connecting rod that is positioned at fixing closure plate below, connecting rod is vertical with screw mandrel lower end and be fixedly connected with, connecting rod outer end is vertically provided with handlebar, handlebar is located on connecting rod and can moves up and down along connecting rod, fixing closure plate lower surface is along being circumferentially evenly provided with at least two and can peg graft location notchs of coordinating upper and lower corresponding with handlebar.
Described locating piece upper surface is connected with the back-up block of collar plate shape, and the circumferential surface of back-up block is evenly provided with at least four spherical grooves, is equipped with and the upper insulated tube inwall ball being connected that rolls in each spherical groove.
Adopt technique scheme, when in needs telescopic adjustment when insulated tube, turning handle bar, drive screw mandrel to rotate by connecting rod, under spacing the stopping of guide pad, the movable block being connected with wire rod thread drives upper insulated tube to move axially, the pilot hole of going up on insulated tube moves axially along guide pad, so just easily quickly action bars is carried out the effect of axial length adjusting, ball on back-up block circumferencial direction play support and feel relieved in insulated tube, also play and reduce the effect that moves axially frictional force.When regulating after length, upwards pushing handle bar, handlebar upper end enters in location notch, between handlebar and connecting rod, have certain frictional force, handlebar also and between location notch is pegged graft and is coordinated, and also has certain frictional force, so just can ensure that handlebar can be inserted in location notch securely, due to by handlebar location, so just can screw mandrel be maintained static by connecting rod, thereby guarantee that the length between upper insulated tube and lower insulated tube keeps stable.
In sum, the utility model is simple in structure, easy operating, regulates very laborsaving, and regulates after putting in place and can keep consistent length constant, thereby improve the fail safe in operating process.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of Manual adjustable insulating bar of the present utility model, comprise lower insulated tube 1 and upper insulated tube 2, upper insulated tube 2 lower ends are plugged in lower insulated tube 1, upper insulated tube 2 upper ends are provided with operating head 3, operating head 3 is existing mature technology, concrete structure repeats no more, upper insulated tube 2 inside, lower end are provided with movable block 4, lower insulated tube 1 lower end is provided with fixing closure plate 5, upper insulated tube 2 is in axial direction arranged with twice pilot hole 6, lower insulated tube 1 upper end is provided with the guide pad 7 through pilot hole 6, between two guide pads 7, be provided with the locating piece 8 of collar plate shape, locating piece 8 external diameters are less than lower insulated tube 1 internal diameter, between locating piece 8 and fixing closure plate 5, be rotatably connected to screw mandrel 9, screw mandrel 9 passes movable block 4 and is threaded with movable block 4, screw mandrel 9, line setting that lower insulated tube 1 and upper insulated tube 2 are concentricity, screw mandrel 9 lower ends are connected with the connecting rod 10 that is positioned at fixing closure plate 5 belows, connecting rod 10 is vertical with screw mandrel 9 lower ends and be fixedly connected with, connecting rod 10 outer ends are vertically provided with handlebar 11, handlebar 11 is located on connecting rod 10 and can moves up and down along connecting rod 10, fixing closure plate 5 lower surfaces along be circumferentially evenly provided with at least two with the location notch 12 of handlebar corresponding and cooperation of can pegging graft Shang Xia 11.
Locating piece 8 upper surfaces are connected with the back-up block 13 of collar plate shape, and the circumferential surface of back-up block 13 is evenly provided with at least four spherical grooves, are equipped with and the upper insulated tube 2 inwalls ball 14 being connected that rolls in each spherical groove.
