The purpose of this utility model is achieved through the following technical solutions：
A kind of insulator crossarm, including cross-arm body, the cross-arm body include plug and are placed on the insulation sleeve of plug appearance,
It is fixed in the middle part of the cross-arm body by the first clip on electric pole, the cross-arm body is provided at both ends with wire clamp connection sheet, institute
State wire clamp connection sheet to be arranged in cross-arm body by connecting rod, the connecting rod can adjust position up and down relative to cross-arm body
Put, be hinged with a supporting rod between the cross-arm body upper connecting rod and electric pole, the first anchor ear is arranged with second armful on electric pole
Bind round, be provided with the adjusting rod parallel with cross-arm body on second anchor ear, the supporting rod other end is provided with sleeve, institute
Sleeve is stated to be placed on adjusting rod.
Further, insulation annular protrusion is provided with the insulation sleeve.
Further, the wire clamp connection sheet is four, and cross-arm body often holds setting two.
Further, three connecting holes, three connecting hole shapes in connection sheet are provided with each wire clamp connection sheet
Into a triangle.
Further, first anchor ear is the cylinder of lower ending opening, and the cross-arm body is fixed on the by fixing card
One anchor ear top surface.
The beneficial effects of the utility model are：
A kind of insulator crossarm of the utility model, can cast out insulator completely, can simplify the installation of transmission line of electricity, improve
Installation effectiveness, moreover it is possible to reduce material cost, can also adjust the height of trolley wire as needed when in use, using more convenient.
Other advantages, target and feature of the utility model will be explained in the following description to a certain extent
State, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or
Person can be instructed from the practice of the utility model.The target of the utility model and other advantages can be said by following
Bright book is realized and obtained.
Brief description of the drawings
In order to make the purpose of this utility model, technical solution and advantage clearer, below in conjunction with attached drawing to this practicality
It is new to be described in further detail, wherein：
Fig. 1 is the utility model structure diagram.
Embodiment
Hereinafter reference will be made to the drawings, and the preferred embodiment of the utility model is described in detail.It is it should be appreciated that it is preferred that real
Example is applied only for illustrating the utility model, rather than in order to limit the scope of protection of the utility model.
As shown in Figure 1, a kind of insulator crossarm, including cross-arm body, cross-arm body include plug 1 and are placed on plug appearance
Insulation sleeve 2, cross-arm body middle part are fixed on electric pole 4 by the first clip 3, and cross-arm body is provided at both ends with wire clamp connection sheet 5,
Wire clamp is set directly in wire clamp connection sheet, and wire clamp connection sheet 5 is arranged in cross-arm body by connecting rod 6, and connecting rod 6 is opposite
Position can be adjusted up and down in cross-arm body, therefore can adjust the height for the wire clamp being fixed in wire clamp connection sheet 5, and then can be adjusted
The height of trolley wire is saved, is hinged with a supporting rod 7 between cross-arm body upper connecting rod 6 and electric pole 4, the first anchor ear 3 on electric pole 4
The second anchor ear 8 is arranged with, the adjusting rod 9 parallel with cross-arm body is provided with the second anchor ear 8,7 other end of supporting rod is set
Sleeve is equipped with, sleeve is placed on adjusting rod 9, sleeve can be limited to position appropriate on adjusting rod, supporting rod by screw thread
Setting can limit cross-arm body rotation, and supporting rod and can also arrive supporting role, can strengthen the fastness of cross-arm body.
Insulation annular protrusion is provided with insulation sleeve, it can improve the retting-flax wastewater of cross-arm, and the definition of retting-flax wastewater is
The ratio between highest operating voltage that the creep distance of equipment outer insulation is born with its both ends, that is to say, that the timing of length one of cross-arm, is set
The cross-arm for having multiple insulation annular protrusions can bear the electric wire of higher voltage without by high electrical breakdown.Certainly, if electric wire
Voltage it is certain, be provided with it is multiple insulation annular protrusions the length that can reduce cross-arm, be arranged on trolley wire phase on cross-arm
