Abstract

The invention relates to an electric power cross arm. The electric power cross arm comprises connecting rods, a clamping device, a locking device and fixing devices, the connecting rods are symmetrically installed at the left end and the right end of the clamping device, the two connecting rods are connected through the locking device, and the fixing devices are evenly arranged on the upper end faces of the connecting rods. According to the electric power cross arm, the stability of the clamping device is guaranteed through concave-convex matching of clamping protruding blocks and clamping grooves, the locking function is achieved through evenly arranging clamping mechanisms on the inner wall of a stepped hole in the circumferential direction of a stepped hole, and the clamping device is prevented from loosening; and rectangular grooves are formed in the connecting rods, fixing elements are installed in the rectangular grooves, the service life of the fixing elements is prolonged, andthe mounting space is saved due to the detachable design of a rotating handle.

Description

technical field [0001] The invention relates to the technical field of power accessories, in particular to a power cross arm. Background technique [0002] The power crossarm is an important part of the tower. Its function is to install insulators and fittings to support wires and lightning conductors, and to keep them at a certain safe distance according to regulations. [0003] During the installation of the power cross-arm, the following problems generally exist: [0004] (1) During the installation process, since the fixing method of the power cross-arm is too simple, the stability of the power cross-arm during use cannot be guaranteed, and loosening caused by various reasons cannot be prevented. [0005] (2) Since the power cross-arm is installed outdoors, the environment faced is relatively harsh, so the service life of the components on the power cross-arm cannot be guaranteed. [0006] In order to solve the above problems, the present invention provides a power cro...
