Abstract

The utility model discloses an antenna diverter. The utility model is mainly composed of a motor, a speed reducer, a gear, a gear sleeve and a rotary supporting frame. The utility model overcomes the defect that the existing antenna diverter can not rotate for 0-360DEG. A plurality of pairs of television receiving antennae can be installed on a supporting rod by the utility model. Thus, the utility model can rotate for 0-360DEG and receive television signals in multi-channel and full direction way. The utility model improves the receiving and watching quality.

Description

Antenna change direction device

The utility model relates to a kind of device of adjusting antenna direction and position, a kind of antenna transfer of more specifically saying so.

Existing television antenna transfer, the general pillar fixed limit that adopts, promptly on motor cover, establish a guide vane end stop, on motor shaft, establish a driving lever, motor automatic reverse rotation when the spacing driving lever of motor shaft touches guide vane end stop, the problem that this mode produces is that the one way corner that motor back and forth rotates can not reach 360 °, has certain dead angle, influences television set signal reception.Present 001 commercially available antenna, reasonable idea, but, can't satisfy user's requirement because of the directional selectivity difference seems stiff, other various bar head dummy steering gear, promptly an installing steering gear in pole top perpendicular to the ground, though also the combination of channel antenna deformation is overpaied in some employing, because oscillator is erected on the same horizontal plane, and receiving phase is identical or differ 180 °, approaching mutually between oscillator, it is little to influence each other, and can't obtain best reception.

The purpose of this utility model provides a kind of Antenna change direction device, can will overpay television receiving antenna installs concentratedly, set up simultaneously, and 0～360 ° turns to, to improve the television reception quality.

Another purpose of the present utility model provides a kind of Antenna change direction device, can set up antenna oscillator in steering gear, realize the multi-faceted reception of multiple spot, and it is minimum to influence each other.

The purpose of this utility model is achieved through the following technical solutions.

A kind of Antenna change direction device, be sleeved on the support bar, include motor-decelerator, runing rest, shell, it is characterized in that locating support is installed on the support bar down, motor-decelerator is installed in down in the cavity of locating support, and gear is installed on the axis of motor-decelerator, the runing rest lower end is set with the tooth cover, gear and tooth cover mesh, and the sleeve of fixed antenna cross bar is arranged on the runing rest, and there is locating cover the runing rest top.

Motor-decelerator is installed on the motor cabinet, and motor cabinet is fixed on down on the locating support.

The aerial yard sleeve is evenly arranged, and has four, and the aerial yard tail end has pullover.

Compare with prior art, the utlity model has following advantage:

1, on a support bar, can install and overpay television receiving antenna, improve the rating quality.

2, the oscillator that erects a television antenna in steering gear can realize the multi-faceted reception of multiple spot, and it is minimum to influence each other.

3, the utility model can make antenna turn to for 0～360 °, does not receive the dead angle.

The utility model is simple in structure, and cost is low, is applicable to that vast rural area and remote districts promote the use of.

Accompanying drawing is the utility model structural representation.

Below in conjunction with accompanying drawing,, the utility model is further described by embodiment.

Embodiment:

Referring to accompanying drawing.The utility model is sleeved on the support bar 1, following locating support 5 is sleeved on the support bar 1, motor-decelerator 4 is installed in down in the cavity of locating support 5, motor-decelerator 4 lower ends are installed on the motor cabinet 3, motor cabinet 3 on following locating support 5, has shell 2 outside the following locating support 5 by screw.Gear 6 is installed on the axis of motor-decelerator 4, runing rest 8 lower ends are set with tooth cover 7, gear 6 and 7 engagements of tooth cover, four sleeves 13 that are used for fixing aerial yard 10 of evenly arranging are arranged on the runing rest 8, the tail end of aerial yard 10 has pullover 9, there is locating cover 11 top of runing rest 8, and locating cover 11 is installed on the support bar 1.Overhead guard 12 only is for needs attractive in appearance and rainproof, is enclosed within the top of support bar 1.

The utility model motor adopts 24V voltage, and power supply and switch place indoor, connects motor-decelerator by electric wire, and electric wire and coaxial wire can be preset in the support bar 1.

During use, only need energized, rotate by motor-decelerator 4 driven gears 6, gear 6 drives tooth cover 7 and runing rest 8 rotates, and then adjusts antenna direction and position.

Claims
