Description
Technical field
The utility model relates to a kind of insulating bar with auto-lock function, belongs to electrical equipment technical field.
Background technology
In the operation maintenance of 10kV power distribution network, be quite large to the proportion shared by fuse switch operation, particularly fuse device failure replacement.Usually, the fuse switch of bar rack type distribution transformer, 10kV distribution line branch, 10kV cable branch etc. is all mounted in road limit, and all installation site is higher, need step on bar when breaking down and work.Work the method for cutting in and out do safety measure, it is also hard to guard against for sometimes having done safety measure, when dislodging cartridge fuse, always on tenterhooks, prevents high-altitude fish accident, particularly ascend a height process time, the working range of people only has about 50cm, and work angle is 25
0left and right, during operation, people faces up head, substantially faces the cartridge fuse of top.When plucking, hanging, cartridge fuse hangs on insulating bar, crumbling, just in case cartridge fuse falls down hindered oneself and other people during operation, although fall from high altitude anti-as the emphasis of safety, due to the impact such as environment, geographical position of operation, or hard to guard against.
In view of this, the present inventor studies this, and develop a kind of insulating bar with auto-lock function specially, this case produces thus.
Utility model content
For preventing fuse switch to fall from high altitude the generation of event, improve operating reliability and fail safe, the purpose of this utility model is to provide a kind of insulating bar with auto-lock function.
To achieve these goals, solution of the present utility model is:
A kind of insulating bar with auto-lock function, comprise insulating bar and the operating head being arranged on insulating bar top, described operating head comprises the screw rod be connected with insulating bar, and the Metallic rod be screwed onto on screw rod, wherein, described Metallic rod comprises the Metallic rod main body vertical with screw rod, Metallic rod main body is connected with connector by connecting rod, connector is screwed onto on screw rod, along with the rotation of screw rod, screw rod, Metallic rod main body, connecting rod and connector form one for placing the operating space of cartridge fuse operation ring seal.
As preferably, described insulating bar and operating head are detachable, the link at insulating bar top is provided with circle first ring gear, screw rod bottom is provided with the second ring gear that a circle matches with the first ring gear, the centre of the first ring gear and the second ring gear is equipped with a screw, coordinated the setting angle of fixed insulation bar and operating head by the first ring gear and the second ring gear, then by the cooperation of screw and wing nut, make operating head firmly be arranged on insulating bar top.
As preferably, the screw bottom described screw rod is opening through hole, forms U-type groove, the design of U-type groove, more convenient when screw rod and insulating bar can be made to fixedly mount.
As preferably, connecting rod and the screw rod of described Metallic rod are horizontally disposed with, between the two apart from being 40-50mm.
As preferably, described Metallic rod is integral type structure.
As preferably, the diameter of described screw rod is 12-16mm, and pitch is 3-5mm, and material is steel.
When fuse switch breaks down or when other needs of work take drop type cartridge fuse, the Metallic rod main body of insulating bar penetrates in drop type cartridge fuse operation ring, then insulating bar is rotated, screw rod is rotated, up move in top, screw tip props up the lower arc surface of Metallic rod main body, now, screw rod, Metallic rod main body, connecting rod and connector form a closed space, thus the operation ring lock of fuse switch in the space that this is closed, pluck, can not slippage be come directly towards from insulating bar and fall down when hanging fuse switch, in addition, when the operation ring width of fuse switch is larger, cannot be locked in closed space, now, arc surface under the operation ring lock of fuse switch is directly propped up by screw tip, it is stably fixed on operating head, from landing operating head when preventing from taking.
The fuse switch cartridge fuse that the insulating bar with auto-lock function described in the utility model can be adapted to different model is extractd and hangs, and has simple for structure, easy to operate, the features such as cost is low.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the insulating bar structural representation of the present embodiment;
Fig. 2 is operating head and the insulating bar link assembling schematic diagram of the present embodiment;
Fig. 3 is the present embodiment operating head and drop type cartridge fuse operation ring connection diagram;
Fig. 4 is the present embodiment operating head and another kind of drop type cartridge fuse operation ring connection diagram.
Embodiment
As shown in Figure 1-2, a kind of insulating bar with auto-lock function, comprise insulating bar 1 and the operating head 2 being arranged on insulating bar 1 top, described operating head 2 comprises the screw rod 21 be connected with insulating bar, and the Metallic rod be screwed onto on screw rod 21, wherein, described Metallic rod comprises the Metallic rod main body 22 vertical with screw rod 21, Metallic rod main body 22 is connected with connector 24 by connecting rod 23, connecting rod 23 and screw rod 21 are horizontally disposed with, distance is 43mm between the two, connector 24 is screwed onto on screw rod 21, along with the rotation of screw rod 21, screw rod 21, Metallic rod main body 22, connecting rod 23 and connector 24 form one for placing the operating space of cartridge fuse operation ring seal.
In the present embodiment, described insulating bar 1 and operating head 2 are detachable, the link 11 at insulating bar 1 top is provided with circle first ring gear 12, screw rod 21 bottom is provided with match with the first ring gear 21 second centre being provided with screw 13, second ring gear 25 in the middle of ring gear 25, first ring gear of installing of a circle and is provided with the through hole of a style of opening, form U-type groove 26, the notch of U-type groove 26 is downward, and the design of U-type groove 26 is more convenient when screw rod and insulating bar can be made to fixedly mount.When insulating bar 1 is connected with operating head 2, first the first ring gear 21 second ring gear 25 dislocation is fixed setting angle, then will both fix tightlies by pad 3 and wing nut 4.Prevent displacement.
Described Metallic rod main body 22, connecting rod 23 and connector 24 is integral type structure.
