Abstract

The invention provides a stopping structure and an antenna downward inclination angle adjusting device, and the stopping structure comprises a fixed part, a movable part and a limiting part, the fixed part and the movable part are detachably connected, an accommodation space is formed by the fixed part and the movable part, and the accommodation space is used for being matched with a transmission screw; the limiting part is arranged on the side, facing the movable part, of the fixed part, the limiting part is used for being matched with the transmission screw so that the stopping structure can be kept static relative to the transmission screw, a first stopping protrusion is arranged on the side, facing the transmission sliding block, of the fixed part, and the first stopping protrusion is used for abutting against a second stopping protrusion on the transmission sliding block. According to the stop structure and the antenna downward inclination angle adjusting device provided by the invention, a stop structure positioning tool and a fastening screw do not need to be used, so that the material cost and the labor cost are effectively reduced, the assembly efficiency is improved, and the stability of the performance of the antenna downward inclination angle adjusting device is ensured, thereby ensuring the indexes and the performance of a base station antenna.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a stop structure and an antenna downtilt adjustment device. Background technique [0002] In the base station antenna, adjusting the radiation angle of the antenna can cover different mobile communication areas, and the phase shifter is a necessary component to realize the adjustment of the downtilt angle of the antenna. By controlling the stroke of the medium in the phase shifter assembly, the The phase of the radiation unit is adjusted, so as to control the downtilt angle of the antenna. [0003] In the prior art, it is generally not suitable for each type of base station antenna to fit a screw with a customized length, and a stop block is often used to limit the stroke of the transmission slider on the screw rod. However, the existing transmission stop block The installation is cumbersome. It is necessary to use the stop block tooling to position the stop block...
