Description of drawings
Fig. 1 is an antenna fluctuating device of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is an A-A place broken section enlarged drawing.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 and Fig. 2 show the embodiment of the utility model antenna fluctuating device.
Antenna fluctuating device of the present utility model comprises antenna installing rack 1, front band 2, lower catch hoop 3, locating flange 4, column hinged-support 5, antenna column 6, column pin 7 and antenna 8; What present embodiment was adorned is plate antenna, but the also antenna of other shapes, antenna 8 is sleeved on the antenna column 6, on this antenna 8, following two ends are provided with antenna installing rack 1, on antenna installing rack 1, downside refills locating flange 4 respectively, antenna 8 is securely fixed on the antenna column 6, described front band 2 is arranged on the antenna column 6, between the antenna installing rack 1 of lower end, lower catch hoop 3 is arranged on the downside of antenna column 6 lower end locating flanges 8, column pin 7 forms column hinged-support 5 and lower catch hoop 3 hinged, antenna column 6 can rotate around column hinged-support 5, finishes the action of holding up or lodge.Described antenna fluctuating device also comprises electronic column swing mechanism 9, and this electronic column swing mechanism comprises connecting rod 91, motor reducer 92, shaft coupling 93, screw mandrel bearing 94, drive lead screw 95, slide block 96, roller 97, link pin 98, track 99 and block bearing 910.The shaft extension of described motor reducer 92 is fixedlyed connected with an end of drive lead screw 95, two of described drive lead screw 95 is bearing on the screw mandrel bearing 94 at two ends respectively by block bearing 910, this screw mandrel bearing 94 is fixedly connected on the floor 10, described slide block 96 kinks are on drive lead screw 95, these both sides, slide block 96 bottom are provided with roller 97, the periphery of described slide block 96 is enclosed within 99 li on described track, this track 99 is fixed on the floor 10, link pin 98 forms the hinged-support 961 and connecting rod 91 lower ends of slide block 96 end faces hinged, connecting rod 91 upper ends form hinged by link pin 98 with the front band 2 that is fixed on the antenna column 6.
