Specific embodiment

In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.

A kind of spotlight antenna as shown in Figs. 1-2, including bracket 10, shell 20, oscillator unit 30, reflecting curtain 40 and tune Section structure 50；Shell 20 is installed over the mount 10, and has inner cavity；The bottom of chamber of inner cavity is fixed with reflected bottom plate 60；Oscillator unit 30 are mounted on top that is interior intracavitary, and being located at reflected bottom plate 60；Reflecting curtain 40 can be mounted on reflected bottom plate 60 with rotating upwardly and downwardly On, and it is located at the side of oscillator unit 30；Adjustment structure 50 includes telescopic rod, and telescopic rod is located at the top of reflecting curtain 40, and The top of telescopic rod is fixed on the housing 20, and bottom end is connect by connecting rope 53 with reflecting curtain 40, wherein can be by connecting rope 53 One end be fixed on the bottom end of telescopic rod, the other end is fixed on reflecting curtain 40, and realizes telescopic rod and reflecting curtain 40 Connection.

When using this spotlight antenna on the basis of above structure, when needing to adjust the tilt angle of reflecting curtain 40, External force makes telescopic rod trail, at this point, telescopic rod and the total length of connecting rope 53 are elongated, reflecting curtain 40 is made in its own gravity Under, the bending of 53 relative telescopic bar of connecting rope is pulled, to realize that the realization of reflecting curtain 40 rotates down；Telescopic rod is received in external force When contracting, the total length of telescopic rod and connecting rope 53 shortens, and connecting rope 53 pulls up reflecting curtain under the drive of telescopic rod 40, to realize that reflecting curtain 40 is rotated up；Furthermore when telescopic rod is not flexible, telescopic rod, which provides, to be made at reflecting curtain 40 In the pulling force of stationary state；In the above process, the rotation of reflecting curtain 40 is realized, that is, has adjusted the inclination angle of reflecting curtain 40 Degree, realizes the adjustment of lobe width, to be suitable for more application scenarios.

Specifically, oscillator unit 30 includes being installed in interior intracavitary two low frequency single polarization oscillators 32 and a high frequency list Polarize oscillator 31；Low frequency single polarization oscillator 32 and high-frequency monopolar oscillator 31 can reflect the signal of different frequency, so that signal Covering surface it is wider, that is, make this spotlight antenna have ultra-wideband frequency of use section；Furthermore using the setting of single polarization, relatively Dual-polarized setting can reduce volume, simplify structure.

More specifically, high-frequency monopolar oscillator 31 is between two low frequency single polarization oscillators 32, and high-frequency monopolar oscillator It is arranged in a staggered manner between 31 and any one low frequency single polarization oscillator 32, avoids high-frequency monopolar oscillator 31 and low frequency single polarization oscillator 32 Front signal interfere with each other, and improve gain.

Preferably, telescopic rod includes the first telescopic segment 51, the second telescopic segment 52 and bolt, and the top of the first telescopic segment 51 is solid Determine on the housing 20, and offers vertically extending multiple first plug-in openings；Second telescopic segment 52 offers the second plug-in opening； Bolt is plugged in the second plug-in opening and any one first plug-in opening；When needing to stretch the telescopic rod, bolt is extracted, mobile the Two telescopic segments 52 move up or down the second telescopic segment 52 according to actual needs when using, and make the second plug-in opening at this time The first plug-in opening being closer to reappears and bolt is inserted into the first plug-in opening and the second plug-in opening, and it is flexible to can be realized first Section 51 and second telescopic segment 52 it is relatively fixed.

Further, bracket 10 includes retaining mechanism, support base 11 and U-shaped fixed arm 12；What fixed arm 12 was open Opposite end is fixedly connected with shell 20 respectively, and is installed in rotation in support base 11；Retaining mechanism will be for that will fix Arm 12 is fixed in support base 11.When retaining mechanism releases the locking to fixed arm 12, fixed arm can be rotated by external force 12, and the angle of radiation of this spotlight antenna is adjusted, improve the convenient degree used；And be locked on arm 12 in retaining mechanism, it is real The now fixation of this spotlight antenna angle of radiation.

Further, the middle part of fixed arm 12 is hinged in support base 11 by articulated shaft, and offers locking hole 121；The regulating tank 111 around articulated shaft circumferentially extending is offered in support base 11；Retaining mechanism includes tie down screw and locking Nut；The bar portion of tie down screw pass through locking hole 121 and regulating tank 111, and with locking nut threaded；At this point, locking Under the head of screw rod and the cooperation of locking nut, be fixedly clamped arm 12 and support base 11, and then realizes fixed arm 12 is fixed In support base 11；And when needing to release the locking to fixed arm 12, turn locking nut or tie down screw make locking screw It is female separate with the head of tie down screw, it can be realized and unlock.

Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to In the utility model range claimed.
