Electric adjusting device with scale regulator

Abstract

The invention discloses an electric adjusting device with a scale regulator. The device comprises a threaded sleeve head, a joint, an upper cover, a shell and a gear transmission mechanism, wherein one end of the joint is clamped with one end of the threaded sleeve head, and the other end of the joint is arranged on the upper cover; the other end of the threaded sleeve head is connected with an electrically-adjustable antenna control port; the shell is fixed at the periphery of the bottom of the upper cover; the shell and the upper cover form a cavity which is used for supporting the gear transmission mechanism; the gear transmission mechanism is positioned in the cavity; one end of the gear transmission mechanism is inserted into a bottom hole of the electrically-adjustable antenna control port to control electrical downtilt, and the other end of the gear transmission mechanism drives a scale ring to rotate and indicates the electrical downtilt. The electric adjusting device with the scale regulator has the advantages that under the condition of small overall dimension, manual electric adjustment and angle indication functions of an electrically-adjustable antenna can be realized, angle reading accuracy is improved, an angle reading range is expanded, the working reliability and maintainability of the electrically-adjustable antenna are improved, and the electrical downtilt can be easily adjusted.

Description

technical field [0001] The present invention relates to a device for adjusting the electrical adjustment antenna, in particular to a device for adjusting the electrical downtilt angle of the electrical adjustment antenna with a built-in scale adjuster for the electrical adjustment. Background technique [0002] The electronically adjustable antenna can realize the flexible adjustment of the antenna coverage, which is convenient for network optimization and can effectively suppress the mutual interference of adjacent sectors. Its characteristics and advantages have been widely recognized and recognized by the industry, and the scale of application is getting larger and larger. [0003] The biggest feature of the electronically adjustable antenna is that the electrical downtilt can be adjusted. There are two main ways to achieve this adjustment: [0004] a. Manual ESC mode [0005] b. Remote control ESC mode [0006] The manual electric adjustment method is to control the el...

Problems solved by technology

[0014] From the above, it can be seen that the existing manual electric adjustment device for electric antenna is large in size, the interval between the engraved lines is small, the reading accuracy is poor, the visual range in the circumferential direction is small, and the operation and adjustment steps are cumbersome. , the reliability of the antenna and manual adjustment device is reduced and it is inconvenient to maintain
