Description
Technical field
The utility model belongs to mechanical field, is related to antenna surface anti-rotation device.
Background technology
In the prior art, the antenna surface anti-rotation of portable antenna more using plunger anti-rotation or threaded connection anti-rotation, installation and
Dismantle cumbersome when antenna surface；It is larger to requirements of installation space, the high height for coming out plunger of meeting on antenna surface surface, no
It is easy to the collection of antenna, and easily causes the damage of colliding with of antenna surface；The antenna surface of portable antenna needs the screw thread in installation plunger
The pre-buried aluminium block of hole position, is unfavorable for antenna surface loss of weight.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of antenna surface anti-rotation device, antenna surface
Dismounting is quick；Antenna surface weight saving；Unnecessary collection height is not increased；Antenna surface without plunger, under collection situation to antenna surface without
Damage；Element precision is low, and processing cost is low；It is simple and reliable for structure, it is easy to assembly.
In order to achieve the above object, the technical solution adopted in the utility model is：
Antenna surface anti-rotation device, including antenna surface 5 and feed component 6, pole is provided between antenna surface 5 and feed component 6
Change component 8, anti-rotation device 4 is provided between polarization component 8, feed locking nut 7, feed locking are provided with feed component 6
Nut 7 is arranged on the top of anti-rotation device 4；
Described anti-rotation device 4 includes main body 1, multiple stop pins 2 is provided with main body 1, between main body 1 and stop pin 2
It is provided with spring 3；
Described feed locking nut 7 is in same vertical plane with stop pin 2.
The beneficial effects of the utility model：
1st, the stop pin of anti-rotation device is pushed by feed locking nut, plays a part of preventing antenna surface from rotating, structure letter
It is single reliable, it is easy to assembly；
2nd, feed locking nut is unclamped, stop pin pops up under the action of the spring, after feed of dismantling, antenna surface
It can screw out, antenna surface dismounting is quick, antenna surface not damaged.
3rd, feed locking nut 7, which is arranged on the position of stop pin 2, is in same vertical plane, and element precision is low, processing cost
It is low.
