[0002] The crossarm is an important component of the pole tower. Its function is to install insulators and hardware to support the conductors and lightning conductors and keep them at a certain safety distance as required.

[0003] For example, the utility model with application number 202022685096.3 discloses a combined insulating crossarm of electric hardware. The combined insulating crossarm of electric hardware proposed in the utility model is provided with an isolating insulating corner plate at the outer corner, and an insulating sleeve is sleeved on the outer side of the crossarm.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of combined power fitting insulated cross arm improves the insulation performance of the cross arm by covering it with an isolating insulating corner plate, but the installation method is still the traditional bolt fixing method. The combined power fitting insulated cross arm is installed on the pole by fixing the clamp, which is not only inconvenient to install but also not suitable for installation on poles of different diameters.

[0006] Therefore, a combined electric power fitting insulating cross arm is designed to optimize the above problems. Utility Model Content

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a combined electric power hardware insulation cross arm. Through the coordinated use of an L-shaped plate, a sliding hole, a sliding rod, a rack, a slider, a fixed block, a rotating shaft, a rack rod, a limit plate, a support plate, an adjusting rod, a limit block, a mounting hole and a movable block, the installation size of the combined electric power hardware insulation cross arm can be adjusted according to the circumference of the installed electric pole, so as to achieve the purpose of a wider installation application range. Moreover, the combined electric power hardware insulation cross arm can be quickly installed on the electric pole by rotating the limit plate, without spending a lot of time on the work of tightening the bolts, thereby improving the installation efficiency of the combined electric power hardware insulation cross arm.

[0017] By using the slide plate, the positioning bolts, the mounting grooves and the mounting holes in coordination, the slide plate is moved laterally along the inside of the L-shaped plate, and after being adjusted to a suitable position, the position of the slide plate is fixed by the positioning bolts, so that the position of the mounting holes and the installation spacing between the insulators can be adjusted. After the slide plate is rotated to a suitable horizontal angle, the positioning bolts are tightened again to adjust the horizontal installation angle of the slide plate, and the installation position of the insulator can be adjusted according to the installation requirements, thereby improving the flexibility of the combined power hardware insulation cross arm;

[0018] Through the coordinated use of the positioning block, the spring and the elastic plate, when the fixing block is fitted to the outside of the pole during installation, the elastic plate on one side of the fixing block will produce a certain deformation according to the diameter of the pole to fit the outside of the pole. Under the elastic force of the spring, the two ends of the elastic plate are pressed against the outside of the pole, increasing the contact area between poles of different diameters and the insulating crossarm of the combined power fitting, thereby improving the firmness of the installation and meeting different installation requirements.
