Abstract

The invention discloses a rotary joint for antenna erection, relates to the technical field of antenna joints, and aims to solve the problem that the number of microwave signal channels capable of being used by an antenna feed system of an existing radar in the prior art is relatively small, so that an antenna and receiving and transmitting power are limited. A collecting ring is arranged at the top of a seven-way rotary joint mechanism, the collecting ring is connected with the seven-way rotary joint mechanism through bolts, the seven-way rotary joint mechanism comprises seven single-way joint sleeves, the outer sides of the single-way joint sleeves are provided with support hinge edges, the support hinge edge and the one-way joint sleeves are arranged to be of an integrated structure, locking bolts are arranged on the outer surface of the support hinge edge, the one-way joint sleeves are connected through the locking bolts, one-way control joints are arranged in the one-way joint sleeves, and each one-way control joint comprises an inner shaft joint, an outer shaft joint and a metal flange plate. And the metal flange plate is arranged at one end of the inner shaft joint.

Description

Technical field[0001]The present invention relates to the field of antenna joint technique, and is specifically a rotating joint for an antenna.Background technique[0002]The antenna is a converter that converts the guide wave propagating on the transmission line, transformed into electromagnetic waves propagating in the unbounded medium (usually free space), or conversion. The components used to transmit or receive electromagnetic waves in the radio apparatus. Radio communication, broadcast, television, radar, navigation, electronic confrontation, remote sensing, radio astronomical engineering system, all of which use electromagnetic waves to deliver information, relying on the antenna to work. Further, in terms of electromagnetic wave transmission energy, the non-signal energy radiation also needs an antenna. The general antenna has reversibility, i.e., the same pair antenna can be used as a transmit antenna, or as a receiving antenna, the same antenna as a basic characteristic par...
