Description

Technical Field

[0001] The utility model relates to the technical field of angle iron cross arms, in particular to a combined line angle iron cross arm. Background Technique

[0002] The combined line angle iron cross arm is a supporting device for overhead lines such as power lines and communication lines. Its main function is to support conductors, cables, etc., to ensure that they can be stably suspended in the air. Through devices such as insulators on the cross arm, the conductors, cables, etc. can be kept at a certain safe distance to prevent contact or collision between them.

[0003] As described in a combined line angle iron cross arm (the authorized announcement is CN 217652467U) disclosed on the patent network, "A combined line angle iron cross arm includes a cross arm body, and rotating components are arranged at both ends of the cross arm body; the rotating component includes a mounting plate located below one end of the cross arm body, a rotating rod penetrating through the cross arm body is arranged on one side of the mounting plate facing the cross arm body, the rotating rod is fixedly connected to the upper surface of the mounting plate, and mounting holes are formed in the mounting plate."

[0004] Regarding the above description, the applicant believes that the following problems exist:

[0005] During the use of this utility model, the mounting plate and the cross arm body are in a horizontal state, and then the limit insertion rod is restored to further fix the position of the mounting plate. At this time, the rotating nut is rotated to fix the rotating rod on the cross arm body. The two ends of the separately placed insertion plate are inserted between the first fixing plate and the second fixing plate, so that the mounting plate has a certain bearing capacity. However, in actual use, when releasing the fixation of the mounting plate, the rotating nut needs to be rotated to loosen the nut on the surface, and then the limit insertion rod is pulled out, so that the position of the mounting plate can be rotated. Moreover, when the nut is rotated, it needs to be repeatedly screwed with tools, and the pulled-out limit insertion rod is easily dropped outside the device, which easily increases the work complexity of the staff during installation and disassembly, and is not convenient for the quick adjustment of the mounting plate. In addition, the device rotatably connects the mounting plate to the bottom of the cross arm body, so the distance between the mounting plates cannot be adjusted according to on-site requirements, making it impossible to change the distance between the installed insulators. Therefore, the combined line angle iron cross arm needs to be improved. Content of the Utility Model
