Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1 to 4, according to the technical solution provided by the present invention: the utility model provides a every single move mechanism for air traffic control radar antenna, includes mount 1, fixed part 2 and radar antenna 3 fixed connection on the mount 1, and the cover is equipped with every single move mechanism 5 on the convex flexion 4 on the mount 1.

The inner side of the bending part 4 is provided with a convex tooth 6, the inner side walls of the bending part 4 positioned at two sides of the convex tooth 6 are symmetrically provided with step surfaces 7, and the outer side wall of the bending part 4 is provided with a limiting groove 8.

The pitching mechanism 5 comprises an upper shell 9 and a lower shell 10 which are of circular arc structures, so that the pitching mechanism 5 is of a detachable structure and convenient to install, maintain and replace at a later stage, the upper shell 9 and the lower shell 10 are fixedly connected through locking nuts on edges, the circle where the bending part 4 is located is concentric with the circle where the upper shell 9 and the lower shell 10 are located, so that the bending part 4 cannot interfere with the upper shell 9 and the lower shell 10 in the moving process, the connection and the fixation are simple, an opening 11 is formed in the middle of the inner side surface of the upper shell 9, a convex tooth 6 located at the opening 11 is meshed with an external transmission structure, so that transmission connection is realized, first rollers 12 are arranged on the inner wall of the upper shell 9 and close to two ends, the first rollers 12 are matched with step surfaces 7 on the bending part 4, and the bending part 4 moves in the using process, and as the first rollers 12 are matched with the step surfaces, the bending part 4 is made to pass through the rolling friction of the first roller 12, the friction force is smaller, and the top surface of the step surface 7 is lower than the tooth crest surface of the convex tooth 6, so that the first roller 12 cannot derail or deviate when the step surface 7 is used in cooperation, the lower shell 10 is connected and fixed with an external fixing device, such as a rotating mechanism, and is adjusted in multiple angles in cooperation with the pitching mechanism 5, a plurality of second rollers 13 are uniformly installed on the bottom side of the inner wall of the lower shell 10, the second rollers 13 are matched with the limiting grooves 8, the moving direction of the bending part 4 is limited by the second rollers 13 in the moving process of the bending part 4, the bending fixing frame 1 is prevented from inclining or deviating, in addition, the first roller 12 and the second rollers 13 are mute rollers, the first roller 12 and the second rollers 13 are made of non-metal materials, such as rubber and the like, so that abnormal sound of the radar antenna in the adjusting process can be reduced, in addition, in order to avoid an excessively large adjustment angle of the bending portion 4, travel switches 14 may be disposed at both ends of the bending portion 4, and when the travel switches 14 contact the upper housing 9, the driving mechanism stops transmission, and transmission may be continued only when adjustment is performed in the reverse direction.

The working principle is as follows: during the use, install last casing 9 and lower casing 10 on flexion 4 earlier, be connected lower casing 10 with outside fixed establishment again, fixed part 2 on the mount 1 is connected fixedly with the upper and lower both sides of radar antenna 3, can accomplish the installation.
