Abstract
The utility model provides a but frequency modulation emit antenna that durability is good, includes T shape antenna frame and cup joints the doublet antenna who connects both ends T shape, doublet antenna is including being responsible for and adjustable vice pole of taking the scale, wherein: vice pole one end is provided with a plurality of screw thread through -hole, hexagonal steel ball screw in having tightened in the screw through -hole, vice pole other end noose has the toper to compress tightly the ring, the toper compresses tightly the incision that the ring side is opened has adjustable pitch cone shape size, vice rod cover connects to be fixed in being responsible for and through the locking of annular knurl lock nut, the utility model discloses it is light and handy pleasing to the eye, convenient to carry, tunable frequency to lasting durability is good.
Description
Technical field
This utility model relates to aerial signal gain techniques field, particularly a kind of Frequency Adjustable generation antenna.
Background technology
In the middle of wireless frequency modulation signal transmission technology field, lower powered signal emitting-source can be amplified propagating farther scope by gain antenna, and by the transmitting length of the doublet antenna of conversion gain antenna, the wireless frequency of transmitting can be changed, the patent No. is: the patent of " CN202487738 " indicates a kind of telescopic frequency modulation antenna device, the slip frequency modulation bar of this device can produce very wide arc gap with fixing bar after having used of a specified duration, slip frequency modulation bar can be crooked downwards due to self gravitation, the quality of the transmitting of this meeting strong influence signal, it is thus desirable to improve.
Summary of the invention
In order to overcome the disadvantages mentioned above of prior art, the purpose of this utility model is to provide a kind of frequency-adjustable, lightly attractive in appearance, easy to carry, the Frequency Adjustable transmitting antenna of durable.
This utility model solves its technical problem and be the technical scheme is that
The Frequency Adjustable transmitting antenna that a kind of ruggedness is good, including T antenna frame and the doublet antenna being socketed in T junction two ends, described doublet antenna includes supervisor and adjustable secondary bar with a scale, it is characterized in that: described secondary bar one end is provided with several tapped through holes, interior hexagonal steel Lunella coronata silk has been tightened in described tapped through hole, described secondary bar other end set has taper and compresses annulus, described taper compresses annulus side and has the otch of scalable taper size, and described secondary bar is socketed in supervisor and is locked by annular knurl locking nut.
As further improvement of the utility model: described Frequency Adjustable transmitting antenna adopts aluminium alloy to make.
As further improvement of the utility model: described T antenna frame is additionally provided with the fixing bar being threaded connection, and fixing bar is provided with mounting plate.
Compared with prior art, the beneficial effects of the utility model are:
This utility model adopts aluminum alloy materials to make, lightly attractive in appearance, easy to carry, by regulating the transmitting length of doublet antenna, the signal of different frequency can be launched, compress annulus by regulating interior hexagonal steel column screw and taper, ensure that secondary bar coordinates closely with supervisor, make transmission signal quality better, it is possible to after avoiding long-time use, secondary bar coordinates crooked with supervisor, causes the behaviour in service of transmission signal quality difference.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the enlarged diagram view of local A；
Fig. 3 is the structural representation that taper compresses annulus.
Detailed description of the invention
Illustrate with embodiment, this utility model to be further illustrated in conjunction with accompanying drawing:
Referring to figs. 1 to Fig. 3, the Frequency Adjustable transmitting antenna that a kind of ruggedness is good, including T antenna frame 1 and the doublet antenna 2 being socketed in T junction two ends, described doublet antenna 2 includes supervisor 21 and adjustable secondary bar 22 with a scale, wherein: described secondary bar 22 one end is provided with several tapped through holes 223, interior hexagonal steel Lunella coronata silk 23 has been tightened in described tapped through hole, described secondary bar other end set has taper and compresses annulus 24, described taper compresses annulus side and has the otch 241 of scalable taper size, described secondary bar 22 is socketed in supervisor 21 and is locked by annular knurl locking nut 25.
The length stretched with hexagonal steel Lunella coronata silk 23 in screwdriver adjustment during use with time supervisor internal diameter, then secondary bar 22 is inserted in supervisor 21, it is inserted in taper from the other end and compresses annulus 24 and annular knurl clamp nut 25, when tightening annular knurl clamp nut 25, notice the frequency scale value stretched out on secondary bar, after adjusting secondary bar 22 extension elongation, tighten knurled nut 25, inside thrust is produced by knurled nut, taper is compressed annulus 24 press inside, taper compresses annulus 24 and is subject to inward pressure, produce to shrink and hold tightly secondary bar, so secondary bar 22 will closely cooperate with supervisor 24, even if supervisor produces abrasion can also adjust the extension elongation of interior hexagonal ball screw and the thrust of knurled nut, make secondary bar will not produce crooked.
Described Frequency Adjustable transmitting antenna adopts aluminium alloy to make, carrying portable, and it can be avoided that gets rusty and affect signal launch mass.
Described T antenna frame 1 is additionally provided with the fixing bar 3 being threaded connection, fixing bar is provided with mounting plate 4, by long antenna mount is split, and the element antenna of two ends symmetry is also to shrink, such entirety is prone to take apart carries, it is possible to the area for some remote signal difference provides facility.
In sum, after those of ordinary skill in the art reads this utility model file, conceive according to the technical solution of the utility model and technology and make other various corresponding conversion scheme without creative mental work, belong to the scope that this utility model is protected.
