Unload, install, be conveniently replaceable and clean, with high use value.
What the purpose of this utility model was realized in：A kind of cross-arm of insulator with rain cover, including cross-arm, insulation
Son, rain cover, described cross-arm are welded in anchor ear, and described anchor ear is secured by bolts on the body of rod of electric pole, described
Insulator is arranged at the outer end top of cross-arm, and bolt hole is set at described insulator central upper portion, and described rain cover is in umbrella
Shape, the center of described rain cover is provided with connecting rod, and the lower end of described connecting rod is installed in bolt hole.
Described insulator is the big ceramic insulator in the small, two ends in middle part.
It is provided with internal thread in described bolt hole, the lower end of described connecting rod is provided with outer with what internal thread mutually agreed with
Screw thread.
Described rain cover and connecting rod are the integrated formed structure of ceramic making.
Described rain cover mouth diameters are 2 times of the upper end diameter of insulator.
Described rain cover oral area horizontal plane is less than 2 ~ 5cm of insulator upper end facial planes.
The utility model produce beneficial effect be：
1st, the utility model sets rain cover on the top of cross arm insulator, it is to avoid rainwater is by insulator and is erected at insulation
Electric wire on son drenches causes electric wire and cross-arm to form the phenomenon of path, is prevented effectively from the generation of leaky.
2nd, the mouth diameters of rain cover of the present utility model are set to 2 times of insulator upper end diameter, and rain cover
Oral area horizontal plane is less than 2 ~ 5cm of insulator upper end facial planes, it is to avoid rainwater drenches electric wire and insulator, energy under the action of the forces of the wind
Enough effectively play rain-proof, the defencive function to insulator.
3rd, insulator top of the present utility model sets bolt hole, and connecting rod is set on rain cover, and the lower end of connecting rod sets
The external screw thread mutually agreed with bolt hole internal thread is put, is easy to dismount rain cover, be beneficial to the replacing of rain cover and right
The cleaning of insulator.

Specific embodiment
Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.
Embodiment 1
As shown in accompanying drawing 1-4, a kind of cross-arm of insulator with rain cover, including cross-arm 1, insulator 2, rain cover 3, institute
The cross-arm 1 stated is welded in anchor ear 4, and described anchor ear 4 is fixed on the body of rod 6 of electric pole by bolt 5, described insulator 2
The outer end top of cross-arm 1 is arranged at, bolt hole 7 is set at the described central upper portion of insulator 2, described rain cover 3 is in umbrella,
The center of described rain cover 3 is provided with connecting rod 8, and the lower end of described connecting rod 8 is installed in bolt hole 7.
Described insulator 2 is the ceramic insulator that middle part is small, two ends are big.
Internal thread 9 is provided with described bolt hole 7, the lower end of described connecting rod 8 is provided with mutually agrees with internal thread 9
External screw thread 10.
Described rain cover 3 and connecting rod 8 are the integrated formed structure of ceramic making.
The described mouth diameters of rain cover 3 are 2 times of the upper end diameter of insulator 2.
The described oral area horizontal plane of rain cover 3 is less than the upper end facial planes 3cm of insulator 2.
The utility model is when in use：A kind of cross-arm of insulator with rain cover, includes cross-arm, insulator, rain cover.It is first
