Abstract
The utility model discloses an azimuth angle adjusting system with a double-spiral-groove shaft for a communication antenna. The azimuth angle adjusting system has a double-spiral-groove shaft structure, particularly a cylindrical shaft structure with two spiral grooves on the surface, is arranged at a lower end position inside a rotating shaft of a communication antenna system, is connected with a screw rod which is fixedly connected with a motor shaft, and is driven by vertical motion transformed from rotating motion of the screw rod; the lower end of the azimuth angle adjusting system is matched and fixed with a fixing sheet arranged on a fixing frame, so that the azimuth angle adjusting system can only move up and down without rotating; and the spiral grooves of the azimuth angle adjusting system is used for clamping a bolt on a rotating shaft shell, so that the rotating shaft is driven to rotate. The azimuth angle adjusting system has a simple structure, is easy to assemble, is convenient to use, and plays a great role in improving the communication antenna system.
Description
Technical field
The utility model relates to communicator, is specially a kind of communication antenna azimuth Adjustment System with double helix fluted shaft.
Background technology
Along with the development that the radio communication cause is maked rapid progress, people are also more and more to the utilization of cordless communication network, though wireless network is gone through wireless optimization personnel's renewal again and again and optimization, still have various problems in many links.
Aspect antenna, antenna is the media that wireless signal receives and sends, and the angular relationship of antenna is good and bad strong and weak to wireless signal, is very important so how to regulate the angle of antenna accurately.But,, be difficult to tackle the problem at its root owing to all be generally after pinpointing the problems by the network optimization and maintenance personal's passive maintenance; General antenna also is difficult to accomplish accurately face correct angle owing to the cause of structure and moulding, thereby the maximization that reaches signal receives.
The utility model content
The technical problem that the utility model solved is to provide a kind of communication antenna azimuth Adjustment System with double helix fluted shaft, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
Have the communication antenna azimuth Adjustment System of double helix fluted shaft, comprise double spiral groove axle construction, be surface band twice spiral fluted cylindrical shaft shape structure, be installed in the lower end position of the rotating shaft the inside of communication antenna system.Described rotating shaft is a hollow structure, and inside is equipped with motor, decelerator, screw rod, bifilar helix fluted shaft from top to bottom successively, and the lower end is with the stator back cover, and there is the fixed mount fixed structure outside, and these devices are formed the azimuth Adjustment System of communication antenna.
Wherein, motor is installed in the top, for the azimuth adjustment of communication antenna system provides initial driving force; Decelerator is installed on the rotation axis of motor, by bolt itself and rotating shaft shell is fixed, and links to each other with screw rod below, is used for rotating speed of motor is slowed down and adjusted, and makes it to drive with a mild speed rotation of screw rod; Screw rod upper end is connected with decelerator, and the lower end is connected with the bifilar helix fluted shaft, utilizes the motion of the vertical direction that its screw thread is converted into the bifilar helix fluted shaft with rotatablely moving of transmitting of motor; The bifilar helix fluted shaft is a cylindrical shaft shape structure, the surface has the twice helicla flute to spiral, corresponding spiral fluted is the fixing bolt on the rotating shaft shell, bifilar helix fluted shaft inside have one screwed hollow, coincide with screw rod, when screw rod drive bifilar helix fluted shaft moves down in vertical direction, by the rotation of helicla flute driven rotary shaft housing, thus the adjustment at drive communication antenna system attitude angle; The bottom of rotating shaft, there is the fixed mount in the vertical rod of being fixed on that rotating shaft is limited, make it to rotate and can not move up and down and wave, bottom at rotating shaft, the stator of band circular hole in the middle of having one, be used for sealing the hollow-core construction of rotating shaft, simultaneously, it fixedlyed connected with fixed mount by bolt.
The lower end of described bifilar helix fluted shaft is provided with a breach, and the stator circular hole also has a breach, and their corresponding and identical blocking guarantees the stable of bifilar helix fluted shaft, makes it only vertically can not rotate to motion.
Beneficial effect
The utility model is simple in structure, and assembling easily, and is easy to use, playing great role aspect the improvement of communication antenna system.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Communication antenna azimuth Adjustment System referring to Fig. 1 with double helix fluted shaft, described communication antenna azimuth Adjustment System comprises motor 1, decelerator 2, screw rod 3, bifilar helix fluted shaft 4, stator 5, fixed mount 8 and rotating shaft shell 7, wherein, motor 1 is installed in topmost, for the azimuthal adjustment of communication antenna provides initial power, the rotation axis of motor 1 links to each other with decelerator 2, be connected to screw rod 3, screw rod 3 is converted into moving up and down on the vertical direction to rotatablely moving of motor shaft and drives bifilar helix fluted shaft 4 and move up and down, and because the helicla flute of bifilar helix fluted shaft 4 is stuck on the bolt 6 that is fixed on the rotating shaft shell 7, rotate so the bifilar helix fluted shaft 4 that moves up and down is driving rotating shaft shell 7.
Described decelerator 2 is fixed on the rotating shaft shell 7 by bolt 6, and simultaneously, bolt 6 also blocks the helicla flute of bifilar helix fluted shaft 4, makes it can not become flexible according to the helicla flute orbital motion.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (1)
1. the communication antenna azimuth Adjustment System that has the double helix fluted shaft, it is characterized in that, comprise bifilar helix fluted shaft structure, be surface band twice spiral fluted cylindrical shaft shape structure, be installed in the lower end position of the rotating shaft the inside of communication antenna system, with link to each other with the fixedly connected screw rod of motor shaft, its helicla flute blocks the bolt on the rotating shaft shell, its lower end coincide fixing with the stator that is installed on the fixed mount.
