Description

Technical Field

[0001] The utility model relates to the technical field of antenna signal reception, in particular to an adjustable antenna lifting rod. Background Art

[0002] Antenna is a kind of converter, which converts the guided wave propagating on the transmission line into electromagnetic wave propagating in the unbounded medium, or vice versa. It is a component used to transmit or receive electromagnetic waves in radio equipment. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., all rely on antennas to work when using electromagnetic waves to transmit information. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas.

[0003] The traditional antenna bottom support rod is not convenient for adjusting its height, so its coverage range is fixed. When used in some areas, signals will be blocked by external factors, which is not convenient for adjustment according to actual needs. This may lead to insufficient signal coverage in some areas and affect communication quality. Therefore, those skilled in the art provide an adjustable antenna lifting rod to solve the problems raised in the above background technology. Utility Model Content

The gears are driven to rotate by controlling the forward and reverse rotation of the lifting motor, so that the lifting column can be raised or lowered, which can facilitate driving the top antenna to adjust its height. The user can adjust the antenna height according to actual needs, thereby optimizing the communication quality and coverage range, avoiding the situation where the signal is blocked in certain terrain environments, and ensuring the integrity of the signal.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Through the above technical solution, the gears are meshed with the tooth grooves, and the two bearings provide limited support for the rotating shaft to improve the rotation stability of the rotating shaft.

[0011] Through the above technical solution, the telescopic rod and the spring drive the oblique clamping block to always be stuck in the limiting hole to fix the mounting block. When disassembly is required, the control bar is pushed toward the front end to compress the spring and the telescopic rod, and the oblique clamping block is retracted to realize disassembly, and it can be directly inserted when installing.

[0012] Furthermore, a base is fixedly provided at the bottom end of the sleeve, and fixing holes are provided at four corners of the base;

[0014] Furthermore, an antenna body is fixedly arranged on the top of the connecting block;

[0015] Through the above technical solution, the antenna body receives the signal.

[0016] Furthermore, a rainproof plate is fixedly provided on the top of the sleeve;

[0017] Through the above technical solution, the rainproof plate can prevent the motor from being exposed to rain on rainy days.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model proposes an adjustable antenna lifting rod, in which the lifting column is inserted into the sleeve, and the gears in the middle of the two bearings mesh with the tooth grooves at the front end of the lifting column. The gears are driven to rotate by controlling the forward and reverse rotation of the lifting motor, so that the lifting column can be raised or lowered, which can facilitate the top antenna to be adjusted in height. The user can adjust the antenna height according to actual needs, thereby optimizing the communication quality and coverage range, avoiding the signal being blocked in certain terrain environments, and ensuring the integrity of the signal.

[0020] 2. The utility model proposes an adjustable antenna lifting rod. When the lifting rod is assembled with the antenna, the mounting block is inserted into the mounting groove. When it is fully closed, the spring drives the telescopic rod to pop out, and the oblique clamping block is inserted into the limiting hole to achieve fixation. When the antenna is disassembled, the control bar is controlled to slide toward the front end, thereby compressing the spring and the telescopic rod, and the oblique clamping block is retracted to achieve disassembly. This structure can facilitate the rapid assembly and disassembly of the antenna and the lifting rod, and can facilitate disassembly for maintenance of the antenna, and can save space when disassembled during transportation.
