Detailed Description
The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
The utility model aims at providing a novel pole cross arm embraces the ring through the initiative of articulated setting and embraces the ring passively to and fix the bolt on the initiative armful ring, can make this workman convenient installation on the pole, simplified work flow, improved the stability and the reliability of installation.
A novel electric pole cross arm comprises a cross arm main body 1 and a fixed mounting piece, as shown in figures 1-3. The cross arm main body 1 is made of angle iron, and the upper end face of the cross arm main body is provided with a part mounting hole, so that the cross arm insulator and other parts can be conveniently mounted.
