Abstract
The utility model relates to a vehicle-mounted omnidirectional antenna take-up and pay-off mechanism used for realizing the simultaneous taking up of a plurality of antennas and applied to the large-scale vehicle-mounted communication equipment. The omnidirectional antenna take-up and pay-off mechanism comprises a base; a motor is mounted in the base and can drive a screw rod above the base to rotate; a nut matched with the screw rod can be driven to vertically move due to rotation of the screw rod; a movable base is connected to the nut; an upper connecting base and a lower connecting base are arranged at the periphery of the root of the screw rod; a plurality of swing links are uniformly arranged at the periphery of each connecting base; the rear ends of the swing links are hinged on the connecting bases; the front ends of two swing links positioned in the position at the same angle on the upper and the lower connecting bases are connected through a connecting rod; the connecting rod is hinged with the two swing links; a vertical antenna is mounted on each connecting rod; a pull rod is connected between each swing link positioned at the upper part and the connected movable base; and two ends of the pull rod are respectively hinged with the middle parts of the movable base and swing links.
Description
Technical field
The utility model relates to a kind of communication equipment, specifically is a kind of many vehicle-mounted omnidirectional antenna jacks that antenna is taken in simultaneously of vehicle-mounted large-scale communication equipment realization that are used for.
Background technology
In ultrashort wave and the microwave communication, run into the situation that many antennas are worked simultaneously through regular meeting.At present, in communication base station, adopt fixed lever to be " ten " word or " rice " word more and intersect and fix many antennas, to reach the purpose that many antennas are worked simultaneously.But on communication vehicle and shelter, make in this way the set-up time longer, weakened the characteristics of its fast reserve, and can not realize automation control.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of many antennas of automatic deploying and retracting simultaneously, easy to operate vehicle-mounted omnidirectional antenna jack are provided.
Vehicle-mounted omnidirectional antenna jack of the present utility model includes a base, motor is installed in the base, the screw mandrel that motor can drive the base top rotates, the rotation of screw mandrel can drive one, and nut engaged is upper and lower mobile with it, has a sliding seat to be connected on the nut and also can together move with nut; The root outer periphery of screw mandrel is equipped with upper and lower two Connection Blocks of fixedlying connected with base, evenly be provided with a plurality of forks around each Connection Block, the rear end of fork is hinged on the Connection Block, the front end that is positioned at two forks of same angle position on upper and lower two Connection Blocks connects by a connecting rod, connecting rod and two forks are and are articulated and connected, and an antenna of holding up is installed on each root connecting rod; Each root above fork and the sliding seat on the above-mentioned nut between be connected with a pull bar, the pull bar two ends are hinged on the middle part of sliding seat and fork respectively, nut upper and lower moved and can drive fork and antenna is packed up and launched by pull bar.
The lower end of described screw mandrel by Bearing Installation on the Connection Block on top, the upper end of screw mandrel by Bearing Installation on a upper bracket, be connected with several columns between the Connection Block on upper bracket and top, have the through hole that passes for column on the above-mentioned sliding seat, column can be led to upper and lower the moving of sliding seat.
Described upper bracket is provided with a lightning rod, so that antenna is carried out lightning protection.
The utility model can pass through many antennas of a motor automatic deploying and retracting, and is easy to operate; Can fall after antenna is packed up,, make things convenient for moving and transportation of mobile unit to reduce space hold; The lightning rod that is provided with in the device can carry out lightning protection to many antennas effectively.
