Description
Technical field
This utility model relates to insulation control, more specifically, it relates to a kind of compound silica gel insulator.
Background technology
Silica gel composite insulator is by glass-epoxy leading-drawing rod, silicon rubber umbrella skirt, and gold utensil three part forms.Narrow passageway can be effectively utilized and open force feed electricity, it is adaptable to city network technology is transformed, and can reduce shaft tower height, substantial amounts of human and material resources and financial resources can be saved, owing to its bending strength is high, the cascade fracture accident that porcelain pole arm easily occurs can be prevented, be the irreplaceable product of porcelain pole arm；Volume is little, lightweight, shockproof, strong shock resistance, does not need hand sweeping, provides safeguard for safe operation.
Now retrieve one section of publication number CN201281988Y Chinese patent document strengthen wind-proof type compound needle type insulator, it utilizes electric wire to be placed in wire grooves, again through screw by platen cover above metallic channel；Often coordinating an insulator pressure wire grooves to be alignd with the screwed hole of pressing plate, fixing by screwing bolt, in work high above the ground, these operating process are excessively various so that the installation of insulator is loaded down with trivial details.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide one to install compound silica gel insulator easily.
For achieving the above object, this utility model provides following technical scheme:
A kind of compound silica gel insulator, including upper gold utensil, lower gold utensil, described upper gold utensil offers appearance wire casing, the sidewall upper portion of described appearance wire casing is provided with sliding chamber, described sliding intracavity sliding is connected to telescopic block, described sliding intracavity is provided with the elastic component abutted with described telescopic block, and described elastic component drives telescopic block to eject sliding chamber.
By adopting technique scheme, holding wire casing and be used for placing electric wire, electrician has only to by simply pressing telescopic block, elastic component be compressed, and then telescopic block is moved towards sliding intracavity, so makes the opening of appearance wire casing increase so that quickly putting into of electric wire；And after electric wire is placed and held wire casing, elastic component carries out return motion under the effect without external force so that telescopic block is placed in the top of electric wire, and electric wire plays the installation process simple and fast of good anticreep effect, whole electric wire and insulator.Elastic component can be spring or gum elastic etc..
It is also preferred that the left it is arc-shaped that described telescopic block deviates from the one end in sliding chamber.
By adopting technique scheme, electric wire when slipping into appearance wire casing, electric wire and this end abutment；The end of arc-shaped is in that line contacts is linear contact lay, and it makes the contact area of telescopic block and electric wire reduce, and reduces the frictional resistance between electric wire and telescopic block, it is simple to electric wire be slides quickly into appearance wire casing.
It is also preferred that the left the bottom surface concave downward of described appearance wire casing forms cambered surface.
By adopting technique scheme, the cross section of electric wire is circular, and the surface of electric wire abuts with holding wire casing bottom surface, and the cambered surface of depression makes the contact area holding between wire casing and electric wire increase, improve the frictional force held between wire casing and electric wire so that electric wire is difficult to depart from appearance wire casing.
It is also preferred that the left one end that described telescopic block is placed in sliding intracavity sets catch, the accent in described sliding chamber is provided with retaining wall, and described catch abuts with retaining wall.
By adopting technique scheme, catch is had barrier effect by retaining wall, it is prevented that telescopic block entirety under the effect of elastic component skids off sliding chamber, and the mechanical function making telescopic block is more stable.
It is also preferred that the left described lower gold utensil includes installing plate, described installing plate offers through hole and pin-and-hole.
By adopting the detent fit on technique scheme, pin-and-hole and electric pole；Lower gold utensil after cooperation has a fulcrum force on utility poles, and electrician can rotate around this pin joint point so that by aliging with the screwed hole on electric pole and screw is fixed, and this design makes insulation more convenient with the installation on electric pole.
It is also preferred that the left be provided with full skirt group between described upper gold utensil, lower gold utensil, described full skirt group includes several full skirts, and the spacing of adjacent full skirt is identical.
By adopting technique scheme, top full skirt is in order to lower section full skirt is antifouling, which reduces the attached dirty amount of insulator, also increases creepage spacing simultaneously.If the distance between full skirt is not of uniform size, certainly will cause that the full skirt spacing that two of which is adjacent increases, then above this position, lower section full skirt antifouling property is weakened by full skirt, is unfavorable for the anti-breakdown performance that insulator is overall.
It is also preferred that the left be provided with column in the upper gold utensil place held between wire casing and full skirt group, the outer wall of described column is provided with annular groove.
By adopting technique scheme, the purpose of design of column is in that to be easy to the gripping to insulator of electrician, and annular groove is easy to electrician's embedding at thumb Yu forefinger so that electrician grips more comfortable during insulator, convenient.
It is also preferred that the left two walls of described annular groove are annular cambered surface.
By adopting technique scheme, annular cambered surface makes annular groove and contact surface between electrician's finger increases, and decreases the insulator pressure to forefinger so that it is more comfortable, convenient that electrician grips insulator, improves electrician's installation effectiveness to insulator.
Compared with prior art the utility model has the advantage of: being placed in the electric wire holding wire casing and abut with telescopic block lower surface, electric wire is played good anticreep performance by telescopic block, and telescopic block is stretched convenient so that it is more easy that electric wire is placed in the operation holding wire casing.
