Abstract

The utility model provides a shackle insulator, which comprises an insulator bod, be equipped with four big full skirts on the middle part outer wall of insulator body, be equipped with a cyclic annular location boss on the outer wall of insulator body lower part, the insulator body is in be equipped with a ring groove between cyclic annular location boss and the full skirt, insulator body edge self the central axis is equipped with the blind hole, be equipped with the screw rod in the blind hole, the screw rod is fixed in in the blind hole, during the insulator installation, the screw rod passes the mounting hole fit in that the installed part is corresponding and screws up. Adopt the design of blind hole to save a large amount of steel quantities to electromechanical and the didirtresistance ability of the effectual improvement of insulator original paper enables. The problem of through -hole intermediate metal through bolt long -term exposure rusing to the metal -ware under wind and rain infiltration erosion environment is solved.

Description

A kind of shackle insulator
Technical field
The utility model relates to transmission line equipment field, particularly relates to a kind of shackle insulator.
Background technology
Butterfly ceramic insulator is the insulator of the butterfly be made up of electrotechnical ceramics, for fixing distribution line terminal, as insulation and fixing cord use on angle pole, is also widely used in circuit suspension insulator simultaneously and coordinates.The porcelain piece of shackle insulator is with the larger full skirt of two or four, and shape is as butterfly.
The butterfly ceramic insulator of prior art, the centre of insulator body is provided with through hole, the structure of through hole needs longer drift bolt when installing and using and installs inconvenience, complex operation, complex procedures when installation, is not easy to use in the power construction of work high above the ground in the wild.
Utility model content
The technical problems to be solved in the utility model, is to provide a kind of shackle insulator, solves existing shackle insulator and installs inconvenience, complex structure, unhandy problem.
The utility model is achieved in that a kind of shackle insulator, comprise insulator body, the middle part outer wall of described insulator body is provided with four large full skirts, the outer wall of described insulator body bottom is provided with an annular locating lug boss, and described insulator body is provided with an annular recess between described annular locating lug boss and full skirt; Described insulator body is provided with blind hole along its center axis; Be provided with screw rod in blind hole, described screw rod is fixed in blind hole, and when described insulator is installed, screw rod was tightened through the installing hole that installed part is corresponding interior cooperation.
Wherein, described screw rod is fixed in blind hole by adhesive.
Wherein, the bottom of described blind hole is hemisphere face.
Wherein, described blind-hole bottom is provided with resilient coating, and described resilient coating is silicon sulfide resilient coating.
The utility model has the advantage of:
The design of one, employing blind hole saves a large amount of rolled steel dosage, and insulator original paper can be made effectively to improve electromechanics and antifouling property.
Two, solve through hole intermetallic metal drift bolt and be chronically exposed to problem of corroding to metal-ware under wind and rain infiltration etch environment.
Three, solve the problem of power construction personnel field high altitude operation fitting operation complex procedures, reduce installation difficulty.
Accompanying drawing explanation
Fig. 1 is the structural representation of shackle insulator of the present utility model
The large full skirt-5 of insulator body-1 annular recess-2 annular locating lug boss-3 blind hole-4
Resilient coating-6 hemisphere face-7.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
Consult shown in Fig. 1, a kind of shackle insulator, comprise insulator body 1, the middle part outer wall of described insulator body 1 is provided with four large full skirts 5, the outer wall of described insulator body 1 bottom is provided with an annular locating lug boss 3, and described insulator body 1 is provided with an annular recess 2 between described annular locating lug boss 3 and full skirt; Described insulator body 1 is provided with blind hole 4 along its center axis; Be provided with screw rod in blind hole 4, described screw rod is fixed in blind hole 4, and when described insulator is installed, screw rod was tightened through the installing hole that installed part is corresponding interior cooperation.In present embodiment, described insulator body is by blind hole 4, and screw rod becomes an insulator original paper by adhesive with insulator body entire combination, changes in prior art the mode adopting through hole, saves a large amount of raw material.Be arranged at the annular recess 2 in insulator body 1 and annular locating lug boss 3, when adopting solder welding, melt solder can springtail in this annular recess 2, just firmly metal installation base can be fixed on insulator body 1 outer wall without the need to arranging metal shelves ring herein, thus make the fitting operation of installation component more convenient.
In above-mentioned execution mode, the bottom surface of described blind hole 4 is hemisphere face 7, and the end face of described screw rod adopts the head matched with described hemisphere face 7, makes the two tight connecting, prevents from leaving space.The face of described hemisphere face 7 is provided with resilient coating 6, and described resilient coating 6 preferably adopts sulphurated siliastic resilient coating 6.Resilient coating 6 described in employing, the resilient coating 6 described in when bolt is fit in described blind hole 4 can play the effect of buffering, and preventing insulator body 1 to be subject to shock energetically and producing crack etc. affects quality.
The embodiment of the utility model shackle insulator is only described in upper; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
