The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific embodiment
Technical solution described in the utility model is described in further detail in the following with reference to the drawings and specific embodiments, with
Those skilled in the art is allow to be better understood from the utility model and can be practiced, but illustrated embodiment is not as to this
The restriction of utility model.
Please refer to Fig.1,2 and Fig. 3, there is disclosed a preferred embodiments of the utility model antenna for base station.In the present embodiment
In, antenna for base station includes reflecting plate 10, oscillator row 20, phase shifter mechanism 30 and driving mechanism 40.
Reflecting plate 10 is made of metal material.Oscillator row 20 are arranged on 10 one side of reflecting plate, and oscillator row 20 have multiple shake
Son 210.Phase shifter mechanism 30 is arranged on the opposite side of reflecting plate 10.
Referring to Fig. 2, phase shifter mechanism 30 has substrate 310, the band line 320 being covered on substrate 310, is articulated in substrate
Coupling piece 330 and the pull rod 340 that coupling piece 330 is driven to rotate on 310.The signal of input is delivered to accordingly with line 320
Oscillator 210.Pull rod 340 drives overcoupling piece 330 to rotate, and so as to become itself and the distance with 320 both ends of line, therefore can change defeated
Send the phase of the signal to corresponding oscillator 210.
Fig. 2 and Fig. 3 are referred to, driving mechanism 40 has drive motor 410, screw rod 420, limiter 430, support base 440
And pivotal block 450.Drive motor 410 is fixed on reflecting plate 10, and drive motor 410 have can turn under electric drive
Dynamic pivot 411.Screw rod 420 is fixed on pivot 411.The screw rod 420 be equipped with screw thread, and offered on screw rod 420 along
The axially extending fluting 421 of screw rod 420.Limiter 430 being set on screw rod 420 along screw rod 420 in axial sliding.For just
Slide axially and prevent limiter 430 from being rotated around screw rod 420 along screw rod 420 in limiter 430, limiter 430, which has, to be stretched
Enter the sliding block 431 in fluting 421.The limiter 430 is also equipped with mounting hole 432.In the present embodiment, mounting hole 432 runs through
Limiter 430 so as to be fixed on fluting 421 after screw is passed through mounting hole 432, and then is fixed on screw rod 420 by sliding block 431
On.Additionally due to mounting hole 432 runs through sliding block 431, after limiter 430 is fixed on screw rod 420, because of consolidating for limiter 430
Positioning is equipped with when by mistake needing that limiter 430 is fixed on screw rod 420 again again, and the spiral shell on screw rod 420 can be destroyed to avoid screw
Line.
Support base 440 is fixed on reflecting plate 10, and one end being fixed on pivot 411 of support base 440 and screw rod 420
Opposite other end pivot joint, so as to balance screw rod 420.
Pivotal block 450 is articulated on screw rod 420, and it is fixedly connected with pull rod 340.
When drive motor 410 drives pivot 411 to rotate, pivot 411 drives screw rod 420 to rotate, so as to which screw rod 420 drives
Axial movement of the pivotal block 450 along screw rod 420, and then pull rod 340 is driven to move, therefore can change and be delivered to corresponding oscillator
The phase of 210 signal.When needing to set 340 mobile range scope of pull rod, by adjusting limiter 430 on screw rod 420
Corresponding position is moved to, limiter 430 is then fixed on screw rod 420 i.e. 340 mobile range scope of compensation linkage.
Since the utility model antenna for base station by adjusting limiter 430 on screw rod 420 is moved to corresponding position, then
Limiter 430, which is fixed on, can limit the moving range of pivotal block 450 on screw rod 420, be moved so as to adjusting yoke 340
Amplitude range, and then driving mechanism 40 can match different antenna for base station, thus provide the matching of driving mechanism 40.
It these are only the preferred embodiment of the utility model, it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly used in
Other related technical areas are equally included in the patent within the scope of the utility model.
