Usual province, city, radio station at county level broadcast signal transmission be built up on high mountain, adopt custom-designed steel tower to erect a television antenna, its structure, highly, produce, install have special requirement。And ring broadcast for village of emergent village, rural area, adopting wireless frequency modulation to launch is a kind of quick construction, mode with low cost, is particularly suitable for the landform such as hills, mountain area。It is also required to erection transmitting antenna (small-power frequency modulation transmitter antenna) in such cases。Owing to the small-power volume of frequency modulation transmitter antenna own is little, lightweight, adopt steel towers to be set as Ben Gao and inapplicable。The at village level this small-power frequency modulation transmitter antenna in current small towns is all be erected on enclosure wall, trunk or on self-control iron, and for the stability of erection, lightning protection measures, on transmitter power impact etc. all without making consideration。
Utility model content
The utility model proposes a kind of antenna holder, solve in prior art middle low power frequency modulation transmitter antenna installation unstable, nonstandard problem。
A kind of antenna holder of the present utility model, including: base, vertical rod and cross-arm, described vertical rod is fixed in the sleeve of described base, and described cross-arm is perpendicular to described vertical rod, and can be rotationally mounted in described vertical rod along described vertical rod axis；Described cross-arm includes: the first cross bar, the second cross bar and longitudinal rod, described first cross bar and the second cross bar are parallel, first cross bar and respective first end of the second cross bar can be rotationally mounted in described vertical rod along described vertical rod axis by rolling bearing, second end is connected by described longitudinal rod, at least one support bar is installed between described first cross bar and the second cross bar slidably, described base is additionally provided with through hole。
Wherein, described vertical rod is at least two joint and extension type vertical rods, is often equipped with least one set for installing the rolling bearing of described cross-arm in joint vertical rod。
Wherein, described vertical rod is uniformly provided with three bracing wires along its circumference and connects sheet, and bracing wire connects sheet and is provided with hole。
Wherein, described vertical rod top is provided with discharging rod。
Antenna holder simple in construction of the present utility model, easy to assembly, and also cost of manufacture is low, it is possible to small-power frequency modulation transmitter antenna stabilization set up。
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。
Fig. 1 is a kind of antenna holder structural representation of the present utility model；
Fig. 2 is the enlarged drawing that in Fig. 1, bracing wire connects sheet place。
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。
As illustrated in fig. 1 and 2, a kind of antenna holder of the present embodiment, including: base 1, vertical rod 2 and cross-arm 3。Vertical rod 2 is fixed in the sleeve 11 of base 1。Cross-arm 3 is perpendicular to vertical rod 2, and can be rotationally mounted in vertical rod 2 along vertical rod 2 axis。Cross-arm 3 includes: the first cross bar the 31, second cross bar 32 and longitudinal rod 33, first cross bar 31 is parallel with the second cross bar 32, first cross bar 31 and respective first end of the second cross bar 32 can be rotationally mounted in vertical rod 2 along vertical rod 2 axis, and the second end is connected by longitudinal rod 33。Antenna is fixed on cross-arm 3, in order to facilitate the fixing of difformity antenna, is provided with at least one support bar 34 slidably between the first cross bar 31 and the second cross bar 32。Base 1 is additionally provided with through hole 12。
Wherein, the first cross bar 31 is arranged in vertical rod 2 by rolling bearing (the first cross bar 31 and the second cross bar 32 corresponding rolling bearing respectively) with the second respective first end of cross bar 32, so that whole cross-arm 3 can rotate along vertical rod 2 axis。Specifically, vertical rod 2 is passed the interior steel ring of rolling bearing and is fastened in interior steel ring, first cross bar 31 and respective first end of the second cross bar 32 are removably mounted on the outer rim of rolling bearing, can by arranging anchor ear at the first cross bar 31 and respective first end of the second cross bar 32, thus respective first end being removably attached on the outer rim of rolling bearing (other connected modes can certainly be taked)。Antenna is fixed on cross-arm 3, adjusts the orientation of antenna by rotating cross-arm 3, it is possible to find the orientation that antenna is suitable more quickly。First cross bar 31 and the second respective opposite side of cross bar 32 are respectively arranged with a chute, and the two ends of support bar 34 are positioned at chute。
The base of the antenna holder of the present embodiment there is through hole, through through hole, antenna holder is fixed by screw, then small-power frequency modulation transmitter antenna is fixed on cross-arm, simple in construction, easy to assembly, and cost of manufacture is low, it is possible to small-power frequency modulation transmitter antenna stabilization is set up。
In the present embodiment, vertical rod 2 is at least two joint and extension type vertical rods, is often equipped with least one set (two) in joint vertical rod 2 for installing the rolling bearing of cross-arm 3 such that it is able to be conveniently adjusted the setting height(from bottom) of antenna。
In the present embodiment, vertical rod 2 is uniformly provided with three bracing wires along its circumference and connects sheet 4, and bracing wire connects sheet 4 and is provided with hole, and hole is used for wearing bracing wire。Bracing wire is for straining to three directions so that antenna holder is more firm。
In the present embodiment, vertical rod 2 top is provided with discharging rod 5, for lightning protection。
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
