Description

Teledish location adjusting mechanism

Technical field

The utility model relates to a kind of teledish location adjusting mechanism, and particularly a kind of load is light, drive current is low, can use the location of single coaxial cable to adjust structure.

Background technology

The used teledish of existing satellite television is for receiving several above satellite signals, usually install a kind of detent mechanism of adjusting direction, use the reception angle of regulating antenna, to receive the signal of different satellites, and known teledish is because the design of its adjusting mechanism makes gravity load bigger, therefore, when rotating, it needs higher electric current (being about 36V, 1.5-2.5A), so satellite signals and power supply can't be located at same coaxial cable (the anti-electric current of general coaxial cable is 0.5Amax), make in installing, quite to bother and waste material.

Summary of the invention

The purpose of this utility model provides a kind of teledish location adjusting mechanism, make the center of gravity and the body of rod of teledish form same axis, thereby reduce gravity load and overall load is alleviated, to reduce its drive current, and can when installing, use single coaxial cable, thereby material and operating cost have been reduced.

The utility model is to realize like this, a kind of teledish location adjusting mechanism comprises: a fixed mount, generally be the U shape, its apical margin is made as skewed locking part, be provided with fixing hole respectively in locking part, for connecting a body of rod, the leading edge below does not have the fixed lever of a pipe shape, for the teledish locking, the below inner edge then is provided with a brace; One body of rod by upper and lower body of rod institute and close, is provided with forward and backward open-work in the last body of rod, and in this-front and back ends of the following body of rod is respectively equipped with the axle center of projection, for the fixing hole fit locking of fixed mount locking part; Two arcuation lamellar bodies are located at antenna holder, and its surface is provided with arc chute and fixing hole, and, back open-work former for the last body of rod is individually fixed in this chute and fixing hole, can swing shape and be; One electric pushrod is fixed in the brace of fixed mount with locking plate, and its front end is locked on an end of a brake(-holder) block, and makes the end in addition of this brake(-holder) block be locked on down body of rod root edge side; This teledish is by the displacement of the body of rod along the chute of lamellar body, and electric pushrod promotes braking when flexible, forms the pitching of this teledish and the location adjustment of left and right sides angle.

Because teledish is located at lower position, overall load is alleviated, and drive current can be reduced to about 0.2-0.22A, can adopt single coaxial cable when therefore installing.

Below in conjunction with accompanying drawing characteristics of the present utility model are elaborated.

Label declaration: 1 fixed mount; 11,12 locking parts; 111,121 fixing holes; The body of rod on 13; Open-work before 131; 132 back open-works; 14 times bodies of rod; 141,142 axle center; 15 fixed levers; 16 braces; 2 teledish; 3 lamellar bodies; 31 supports; 32 chutes; 33 fixing holes; 4 electric pushrods; 41 locking plates; 5 brake(-holder) blocks.

Embodiment

Referring to Fig. 1, Fig. 2, the utility model is provided with the fixed mount 1 that without exception is the U shape, make the apical margin of this fixed mount be made as

skewed locking part

11,12 and establish respectively with fixing hole 111,121, be locked in this locking part 11 for the body of rod up and down 13,14 that connects in the lump at locking

part

11,12; Wherein, the two ends of this time body of rod 14 are respectively equipped with the axle center 141,142 of projection, after making this fixed mount 1 be sleeved on axle center 141,142 respectively with fixing hole 111,121, be locked on axle center 141,142 with nut, make this fixed mount 1 be able to axle center 141,142 and be fulcrum, constitute rotary shape, it is square tube and lower edge is the fixed lever 14 of pipe shape that the leading edge below of fixed mount 1 connects upper limb, makes a dish-shaped antenna 2 be fixed in this fixed lever 14:

Two arcuation lamellar bodies 3 are locked in antenna holder 31, and its surface is respectively equipped with the chute 32 and the fixing hole 33 of arcuation, make the body of rod 13 of fixed mount 1 be individually fixed in this chute 23 and fixing hole 33 with its forward and backward open-work 131,132, can swing shape and be;

One electric pushrod 4 is fixed in the set brace 16 of fixed mount 1 inner edge with a locking plate 41, and after making its front end be locked on an end of L shape brake(-holder) block 5, makes the fixing root edge side of the body of rod 14 down of doing of end in addition of this brake(-holder) block 5, makes it be rotary shape;

By the combination of aforementioned components, this teledish 2 is by the slippage of the body of rod 13 along the chute 32 of lamellar body 3, bow to constitute it, the adjustment of elevation angle degree, and flexible to drive fixed mount 1 rotation by electric pushrod 4, constitute the left and right sides angle adjustment of teledish 2.

Because whole transmission mechanism is to fall teledish 2 to be located at the position of below and to make the whole center of gravity of antenna very near rotating shaft, make load reduction, when electric pushrod (4) in when action, can reduce its power consumption stream (being about about 0.2-0.22A), therefore, transmission signal and power supply single coaxial cable be can be located at, material and construction cost saved.

Referring to Fig. 3, the utility model moves the body of rod 13 of being located at fixed mount 1 top when adjusting teledish 2 luffing angles along the chute 32 of lamellar body 3; Whole fixed mount 1 is moved up and down thereupon, relatively constitute the luffing angle adjustment of teledish 2.

As shown in Figure 4, the utility model makes electric pushrod 4 be flexible action when the angle of the left and right sides of adjustment teledish 2, relatively makes fixed mount 1 left-right rotation thereupon to promote brake(-holder) block 5, to constitute the whole left and right sides of this teledish angle adjustment.

In sum, the utility model cooperates the arcuation lamellar body with U shape fixed mount, and electric pushrod, makes teledish reduce its drive current because of load reduction, and can use single coaxial cable when installing, to reduce Master Cost and construction cost.
