Description
Technical field
The invention belongs to experiment device for teaching technical field, more particularly to a kind of teaching experiment antenna E-H faces to test
Quick switching device.
Background technology
It is to lift student to experiment in the teaching experiment activity of colleges and universities' Electronics and Information Engineering class skilled antenna class course
The interest and teaching experiment effect of course, deepen understanding of the student to antenna foundation knowledge, make Students ' Learning and grasp antenna survey
Examination technology, the practical operating abilities and engineering sense of training student are, it is necessary to carry out the E-plane and H-plane pattern of various antennas
Test experiments.At present, the fixed form of teaching experiment antenna is to be fixed on by adaptor on antenna rotating platform mostly, and tests day
It is immovable between line, adaptor, antenna rotating platform three.And the extensive use with antenna measurement technology in education activities, it is real
During testing, testing the E faces of antenna and H faces needs frequently to toggle.
At present, during the E-plane and H-plane pattern test experiments of various antennas are carried out, when experiment antenna E faces and H faces
When needing switching, typically by changing different adaptors.And test between antenna, adaptor, antenna rotating platform three and be usually
Screw fastens, and changing adaptor then means at least to turn the fixing screws, adaptor and the antenna that test antenna and adaptor
Fixing screws between platform will dismount one time., it is necessary to which antenna rotating platform is adjusted into suitable height during dismounting, torn open with facilitating
Dress.If antenna is larger, or heavier, then needs the even more people of two people to coordinate and carry out.In addition, traditional adaptor and antenna rotating platform
The connecting rod of docking is usually polished rod, and traditional adaptor leaves the mounting surface for testing antenna for and mounting hole is also more single.
The shortcomings that prior art, mainly includes：1st, because various types of antenna structures are different, cause to carry out different types of
When antenna measurement is tested, when needing to change antenna, it is necessary to change different adaptors.2nd, because antenna structure is fixed, cause out
When opening up antenna E-plane and H-plane pattern test experiments of the same race, it is also desirable to change (or increase and decrease) different adaptor.3rd, adaptor
Increase with the increase of antenna amount, management and the identification difficulty increase of adaptor.4th, either antenna, adaptor or day
The possibility for accelerating damage all be present by frequently dismounting in line turntable, mounting hole.When the 5th, changing adaptor, it usually needs adjustment
The height of antenna rotating platform, further increases unnecessary operations, and efficiency is low.6th, when antenna is larger, or it is heavier when, it is necessary to two
The even more people of people, which coordinate, to be carried out, and is wasted time and energy.7th, the connecting rod of traditional adaptor and antenna rotating platform docking is usually polished rod, when this
After connecting rod insertion antenna rotating platform, holding screw is directly withstood on the smooth, cylindrical peripheral surface of connecting rod, fixed illusive wind be present
Danger.When because fixation is not firm and caused by connecting rod slide up and down when, holding screw can also scratch the face of cylinder of connecting rod.8th, pass
System adaptor and mounting surface, the mounting hole of experiment antenna docking are single, cause part Experiment antenna needs to increase adaptor in addition
It could install.
Therefore, the prior art is defective, it is necessary to improve.
The content of the invention
The technical problems to be solved by the invention are in view of the shortcomings of the prior art, there is provided a kind of teaching experiment antenna E-H
Quick switching device is tested in face.
Technical scheme is as follows：
Using such scheme, the fast conversion method in the antenna E-H faces in teaching experiment is realized.This method is to pass through one
Individual simple 90 ゜ rotations, carry out quick locking by a bearing pin after being rotated in place, so as to realize the switching in antenna E-H faces, cut
Process is changed without other operations, one can complete for several seconds.In addition, the conversion equipment in the present invention, itself and antenna rotating platform dock
Connecting rod, there is anti-skidding groove, can overcome because antenna weights are larger and fix it is not firm produced by slide up and down.
