Abstract
The utility model discloses a tapered screw-thread fit device for fixing a core rod of a composite insulator of an overhead power-transmission line, and the device comprises a connecting sleeve. The upper end of the connecting sleeve is provided with a tapered thread hole. The interior of the tapered thread hole is provided with a finger-shaped tapered external threaded pipe in screw-thread cooperation, and is also provided with a clamping hole which cooperates with the core rod of the composite insulator in a diameter cooperation manner. The device provided by the utility model is simple in structure, and is easy to install. A core rod clamping strip can firmly press the core rod of the insulator, thereby effectively preventing the severe accident that a wire falls to the ground, and adverse effects, wherein the accident and the adverse effects are all caused by the brittle break of the core rod of the composite insulator.
Description
Technical field
The utility model relates to insulator jockey, is specifically related to the overhead power transmission line composite insulator plug fixture that tapered thread coordinates.
Background technology
That composite insulator has is lightweight, good antifouling effect and the advantage such as operation maintenance workload is few, in the construction of electrical network with in servicely obtain a large amount of uses.But along with the sharp increase of composite insulator usage quantity, its fault and rate of failure also mouth become to increasing, especially composite electric insulator core bar Fragile Split, though probability of happening is little, consequence is serious, even may cause the generation of electrical network serious accident.
In order to address the above problem, number of patent application is that CN201210086116.2 discloses a kind of built on stilts electric power transmission line compound inslation sub-connecting device, and this apparatus structure is more complicated, and installation process is more loaded down with trivial details.
Utility model content
For compound inslation sub-connecting device in prior art, this apparatus structure is more complicated, the problem that installation process is more loaded down with trivial details, the overhead power transmission line composite insulator plug fixture that the utility model provides a kind of tapered thread simple in structure to coordinate.
To achieve these goals, the technical solution adopted in the utility model is: the overhead power transmission line composite insulator plug fixture that tapered thread coordinates, comprise branch sleeve, branch sleeve upper end is conical screw hole, in conical screw hole, be the finger-like conical external screw thread pipe of threaded engagement, in finger-like conical external screw thread pipe, establish the clamping hole coordinating with composite electric insulator core bar diameter.
The index of described finger-like conical external screw thread pipe is one of in 2,3,4,5.
The finger of described finger-like conical external screw thread pipe be with coordinate with plug circular-arc.
Beneficial effect is: the utility model is simple in structure, installs simple and easyly, and plug clamping strip can firmly be pressed on core rod of insulator, can effectively prevent that wire because causing after composite electric insulator core bar brittle failure such as lands at serious accident and the dysgenic generation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the male-pipe schematic diagram in branch sleeve of the present utility model.
Embodiment
As shown in Figure 1, the overhead power transmission line composite insulator plug fixture that tapered thread coordinates, comprise branch sleeve 2, branch sleeve 2 upper ends are conical screw hole 4, in conical screw hole 4, be the finger-like conical external screw thread pipe 3 of threaded engagement, in finger-like conical external screw thread pipe, establish the clamping hole coordinating with composite electric insulator core bar diameter.
As Fig. 2, the index of finger-like conical external screw thread pipe is one of in 2,3,4,5, the finger 5 of finger-like conical external screw thread pipe be with coordinate with plug circular-arc.
The finger 5 of conical external screw thread pipe 3 can firmly be pressed on core rod of insulator, can effectively prevent that wire because causing after composite electric insulator core bar brittle failure such as lands at serious accident and the dysgenic generation.To be enclosed within after core rod of insulator with the conical external screw thread pipe 3 referring to, screw branch sleeve 2 fixing.
