Abstract

The utility model relates to a rotating base for a satellite antenna. One end of a cylindrical base is fixed on a foot rest by a fixing element. A lower shell is arranged at the outside of the fixing element. The other end of the base pivots to a gear seat. A speed reducing gear set and a driving element matched with the speed reducing gear set are fixedly arranged in the gear seat. The speed reducing gear set is fixedly connected with the base by the fixing element. The gear seat is sheathed with an upper shell on the driving element. An outer sleeve is sheathed at the outside of the gear seat which rotates on the base to drive the outer sleeve and a dish-shaped antenna to rotate. The utility model has the advantages of simple structure, rain water erosion prevention, exact receiving angle adjustment and convenience.

Description

The rotating seat of satellite antenna

The utility model relates to antenna, refers in particular to a kind of rotating seat of satellite antenna.

The rotating seat of satellite antenna commonly used divides two classes substantially, one class is that very complicated structure-steel framing is located at open-air place, and its major defect is owing to be exposed in the open, is subjected to the rainwater etch, corrosion can take place, and causes that parts damage, the adjustment deviation of rotating seat is big, the transmission power loss is big and it is big to receive noise; Another kind of be the disc of satellite antenna by the linear actuator transmission, the signal of aiming at artificial satellite is adjusted the angle of disc, its major defect is that linear actuator can't accurately be controlled, and causes the deviation of disc angle, it is bad to cause signal to receive.

The purpose of this utility model is to provide a kind of rotating seat of follow-on satellite antenna, design a kind of rotating seat simple in structure, in pedestal, be provided with pinion stand, train of reduction gears, actuated element and with the outer tube of teledish Joint, rotation by the control actuated element reaches the purpose that makes teledish accurately be adjusted to correct reception angle.

The purpose of this utility model is achieved in that a kind of rotating seat of satellite antenna, it is characterized in that: an end of tubular pedestal is fixed on the foot rest by retaining element, and this retaining element is provided with lower house outward, the other end of this pedestal pinion stand that is pivoted; The actuated element that sets firmly train of reduction gears in this pinion stand and match with it, this train of reduction gears is affixed by retaining element and pedestal, and this pinion stand is sheathed upper shell on actuated element; The outer sheathed outer tube of this pinion stand, this pinion stand rotate on pedestal and drive this outer tube and teledish rotation.

This actuated element comprises motor; Be provided with the spline body between the retaining element of this pedestal and foot rest; This lower house one end is provided with for the ccontaining antenna pedestal of antenna; The face that this pedestal and pinion stand join is provided with most balls, and the corresponding ball of this pinion stand is provided with slide rail, and the rolling of this pinion stand mat ball is rotated on pedestal.

Major advantage of the present utility model be have simple in structure, prevent rain erosion and adjust the reception angle accurately, advantage easily.

That the utility model is described in further detail is as follows below in conjunction with drawings and Examples:

Fig. 1 is a perspective exploded view of the present utility model;

Fig. 2 is a combination cross-sectional schematic of the present utility model;

Fig. 3 is the combination schematic diagram of the utility model and satellite antenna;

Fig. 4 is an adjustment spinning movement schematic diagram of the present utility model.

Consult Fig. 1-Fig. 3, the utility model is provided with the pedestal 1 of tubular, the pinion stand 2 that is pivoted of the end in this pedestal 1, and this pedestal 1 is provided with most balls 21 with the face that pinion stand 2 joins, these pinion stand 2 corresponding balls 21 are provided with slide rail 11, and the rolling of pinion stand 2 mat balls 21 is rotated on pedestal 1.Be provided with train of reduction gears 23 in the pinion stand 2, the end of these pinion stand 2 relative pedestals 1 sets firmly actuated element 3, common motor, and train of reduction gears 23 mat retaining elements 25 are affixed mutually with pedestal 1, when actuated element 3 drives train of reduction gears 23 rotations, and driven gear seat 2 rotates on pedestal 1.Pinion stand 2 outer sheathed outer tubes 27, these outer tube 27 mat retaining elements 271 are affixed mutually with pinion stand 2, and it is affixed mutually with the bracing frame 41 of teledish 4, as shown in Figure 3, when pinion stand 2 rotates on pedestal 1, can drive outer tube 27 and teledish 4 and rotate together, reach the reception angle of adjusting teledish 4.This pedestal 1 is affixed mutually by retaining element 15 and foot rest 13 away from the end in addition of pinion stand 2, be provided with lower house 16 outside the retaining element 15, an end of this lower house 16 is provided with antenna pedestal 161, is provided with spline body 17 between pedestal 1 and retaining element 15, as shown in Figure 1, prevent that outer tube 27 from excessively rotating.Sheathed upper shell 18 on actuated element 3 prevents rainwater intrusion damaged member.One side of pedestal 1 is provided with antenna 19, and its terminal mat joint 191 interconnects with the circuit board (not shown), and this circuit board is between upper shell 18 and pinion stand 2, and this circuit board is controlled the rotating speed of actuated element 3.

Consult Fig. 3 and Fig. 4, when using the utility model, actuated element 3 drives train of reduction gears 23 and pinion stand 2 rotates on pedestal 1, drive outer tube 27 and teledish 4 rotations simultaneously, therefore, can directly make teledish 4 transfer to best reception angle, accurately receive the signal that artificial satellite sends by 3 rotations of circuit board control actuated element.
